Use of corn planter

After purchasing, users should read the "Product Usage Introduction" first and master the usage rules. When necessary, you can participate in the corresponding technical training of agricultural machinery, and truly understand the principles and structure; can operate and maintain; can maintain and manage, so that it will be handy when used, to achieve the purpose of increasing production and income.

(1) Before using, you must read the product manual and relevant parts on the planter carefully. You must know the various performances of the corn planter. Perform specific operations in accordance with the main points of the manual to avoid machine failure. Before each operation, you should check whether the lubricating oil in the transmission part of the planter is sufficient, whether the parts are connected tightly, whether the connecting bolts are tight, and whether each rotating part is flexible. If any abnormal sound is found during the planting operation, the parking inspection should be carried out immediately, the failure should be checked, and the necessary maintenance should be carried out.

(2) During planting, the operator fills the sterilized corn seeds into the cabin of the machine, loads the seeds to be planted into the vibrating tray of the planter, at the same time checks the water supply source, checks the connection of the entire set of equipment, and confirms that it is correct. The control switch can be activated for planting operations. When planting, it can be evenly planted into the soil at a certain depth through a series of operations such as ditching, seeding, covering, and cracking.

(3) In strict accordance with the requirements of the product manual, timely repair and maintenance of machinery.

"Prevention is more important than cure, nourishment is more important than repair" is a basic principle of planting machine maintenance. The specific contents of planter maintenance include: checking and tightening the bolts connecting relevant parts in daily work; inspecting the pins, cotter pins and other wearing parts of the planter for defects, and replacing them if necessary; inspecting the planting related parts If the connection is short of oil, replenish it immediately if necessary; check the appearance of the planting equipment and repaint it if necessary to prevent rust.

Planting machine is an important means of agricultural production and plays an important role in China's agricultural production. Through mechanized planting operations, planting quality can be improved, farmers' labor intensity can be reduced, agricultural production efficiency can be improved, and seeds can be saved. Especially in the drought and little rain, after the planter performs the planting operation, with its characteristics of stubbornness and good emergence, it further shows the superiority of mechanized planting technology, which has a direct impact on the increase of agricultural production and farmers' income.

Shopping for corn planters

With the increasing saturation of the agricultural machinery market, corn planters have become another new rich tool for farmers to increase the input-output rate in the process of planting corn. In the face of various types of corn planters, how to choose the corn planters for farmers to plant better and faster is the most concerned issue. Here are a few points that have emerged from years of practice:

(1) Full consideration must be given to the situation of farmers who use corn planters

The corn planter is suitable for different types of agricultural machinery to drive the situation. When purchasing, farmers can fully consider the horsepower of their agricultural machinery and the degree of their own agricultural knowledge. From the current situation of agricultural machinery users using corn planters, when farmers choose to buy, they must according to their own mechanical technology level, that is, the ability to control and maintain corn planters. In practice, we should try to choose corn planters with simple structure, easy to master, convenient operation, affordable and durable. At the same time, we should observe the performance and choose corn planters that meet the conditions of our tractor.

(2) Fully consider the adaptability of corn planting

For a long time, the row spacing of corn planted in different places has been very different, even the row spacing of corn planted in a natural village is not the same. Therefore, it is one of the grounds for users to choose to find the actual conditions suitable for corn planting in different regions. On the other hand, the natural conditions vary widely from place to place, resulting in a long and scattered corn planting area, different varieties of corn planted, and large differences in farmers' farming levels. In this way, you need to consider the method and convenience of corn planter selection, and you should choose those models with good performance and durability.

(3) Fully consider the natural conditions of the land

At present, since the rural households use the household-to-household household contract management system, this will inevitably result in the division of land for planting. Therefore, the area of ​​corn plantation is mostly small, agricultural machinery has narrow roads when walking in the field, and it is very difficult to enter the ground. When using mechanized corn, it is very important to choose a model suitable for local cultivation. Appropriate models can reduce the labor intensity caused by manual operations; second, they can improve work efficiency and increase the seed emergence rate.

(4) Full consideration must be given to the quality and after-sales service of the planting machine

For the majority of farmers, the corn planter is a new product, so when you buy it, you must pay attention to whether the corn planter has an appraisal certificate from an agricultural machinery appraisal department at or above the provincial level. After knowing these certificates, when purchasing the machine, you must also grasp the use of the planter in a specific cultivated land. To understand the past sales volume and distribution of the planting model, if possible, it is best to consult with old users Then decide whether to buy. The quality of after-sales service of corn planters has an important impact on the long-term use of the planters. The quality of after-sales service determines the economic benefits of corn planters to a certain extent.

How corn harvesters work

It is mainly composed of cutting rod device, conveying device and hydraulic lifter. During operation, the machine advances in the direction of the corn ridge, and the cutter cuts the corn stalks. The stalks are output through the right direction of the upper, middle and lower conveying chains and placed naturally to complete the harvest. The separation of power is when the driver operates the hydraulic lifting system of the tractor. After the host is lifted up to the stopped position, the two B-type V-belts will stop turning and cut off the power input of the diesel engine. The conveyor will stop rotating. Otherwise, it will be in the working rotation.

Installation and commissioning of corn harvester

1: Check whether the front bumper of the tractor is horizontal. If it is not horizontal, first correct it before installing the lifting frame.

2: Install the lifting frame on the bumper of the tractor, then use the pressure plate to tighten the screws, and then connect one end of the two inclined flat irons to the lifting frame, and the other end is connected to the connecting seat welded to the tractor beam fixed. Make sure the machine has good stability.

3: The connection between the host and the elevator is through the four U-shaped cards on the host and the two front supports on the lower part of the lifting frame. The two U-shaped cards on the upper part of the lifting frame then pass the four cylindrical pins and two movable lifting plates to the host. Connected to the lifting frame.

4: The diesel engine and the harvester reducer are connected with two B-type V-belts. After installation, do not press the tightening wheel too tightly. Under normal circumstances, as long as the V-belt does not slip.

5: After assembly, run for 5 minutes at idle speed and 6 minutes at high speed. After checking that there are no abnormalities in each part, you can work in the field.

6: The height adjustment of the stubble is achieved by the adjusting screw of the lifting frame. Before harvesting, first adjust the cutter to contact the soil ground, then lock the screw for a trial cut to see if the stubble is suitable, and if it is not suitable, adjust it to meet the requirements and then start harvesting.

7: Because the harvester is transported on the right side, when harvesting in the field, the harvesting method to improve efficiency is to harvest in circles around the plot.

8: The cutter is made of alloy steel. After using for a period of time, especially after using it on sandy ground, the cutting edge of the cutting blade will wear out and become dull. At this time, the cutting edge should be ground with a hand-held polisher to save power when harvesting. , But to prevent overheating when cutting the edge, dripping to cool down, so as not to reduce the durability of the edge. The corn harvester is an agricultural implement that uses machinery to complete the harvest of corn stalks when the corn is mature or close to maturity.

Operation method and precautions of rice mill

Operation method
1. Place the rice mill on the workbench stably and plug in the power plug.
2. Determine the whitening time and adjust the timing knob.
3. Take out the pressed rice in the hopper, take 17-20g of brown rice (the moisture content should not exceed 15%) and put it into the hopper, and let it flow into the white mill room. After pressing the power button to start, then lower the press button.
4. At the specified time, the rice mill will stop automatically, remove the hopper first, and remove the bran. Plug the receiving hopper, then take out the pressure bar, turn the front handle to the right °, so that the polished rice in the white milling chamber falls into the receiving hopper, set the timing knob to 0, press the power button to idle the grinding wheel for a few seconds, so that All the rice grains in the white mill room are dropped, then the rice bucket is pulled out, and the polished rice is obtained after sieving.
Precautions
1. Before the brown rice enters the falling hopper, it should be checked for metal objects and stones, so as not to damage the grinding wheel.
2. After the milling process is finished, pull out the front rotating block to clean up the remaining sugar in the milling chamber to avoid affecting the accuracy of the sample.
3. The precision of white milling needs to be determined by the variety of brown rice. The number of samples and milling time are suitable. The number of low-precision samples is 17-18g, and the milling time is shorter. The number of high-precision samples is 20g, and the milling time is slightly. long.

4. When the machine has been used for a long time and has been milled over high-moisture brown rice, the rice bran bonding wheel affects the whiteness. You can use a wrench to remove the wheel, use a wire brush to remove the bran powder, and reinstall it as it is.

Main components of rice mill

1.Rice milling room

The rice milling room shown in the figure is the core part of the rice mill. There are hollow shafts, sand rollers, iron rollers, rice sieve, etc. in the rice milling room.

Corn thresher manufacturers portable

The corn thresher is divided into two types: side-mounted and backpack-type:



① The side-hanging automatic harvester adopts hard shaft transmission, which is mainly composed of engine, transmission system, clutch, working parts, operating device, and side-hanging belt. A single-cylinder two-stroke air-cooled gasoline engine and a centrifugal friction clutch of 0.75 to 2 kW are arranged at one end of the transmission shaft; a working part composed of a reducer and a cutting tool is installed at the other end. There are many types of working parts, usually circular saw blades, blades or nylon wires. During operation, the shackle on the aluminum alloy sleeve of the transmission shaft is hung on the strap under the operator's shoulder, holding the handlebar, and swinging the hard shaft laterally, the weeds, shrubs and other tasks can be completed. The weight of the machine is about 6-12 kilograms, and the speed is about 4500-5000 rpm.



② Backpack automatic harvester. Driven by a flexible shaft, the general structure is similar to that of a side-mounted brush cutter, except that the engine is carried on the operator's back, and the cutting parts are driven by a flexible shaft. The engine power is generally 0.75 to 1.2 kilowatts. The engine and the back frame are connected at two points and equipped with special rubber parts to isolate vibration. The flexible shaft is a steel wire flexible shaft sleeved in a hose to transmit torque. The hose is a steel pipe wrapped with a steel braid wrapped with a rubber protective sleeve and wrapped with a threaded pipe to prevent dust and dirt from entering the shaft and maintaining the lubricating oil on the shaft surface. The cutting width is generally between 1.5 and 2 meters.



Walk-behind



The weight of the implement is supported by the walking wheels, the machine is pushed forward by a person, and the working part is driven by the engine to perform the cutting and irrigation operation. Its structure and working principle are similar to portable brush cutters.



hanging



Hanging behind the tractor, the working parts are driven by the power output shaft to rotate, suitable for large-area cutting and irrigation operations. It is mainly composed of frame, saw blade, transmission device, suspension device and push plate. During cutting and irrigation, the tractor runs backwards, with a working speed of 5 km / h, and can saw bushes with a diameter of 10 cm.

Working principle of corn thresher

Corn thresher, as its name implies, is a machine that uses corn threshers to separate corn and corn cob, and is a widely used machine in modern agriculture. So what exactly is a corn thresher? When the corn threshing machine performs corn threshing, the gap between the nails of the nailing drum rotating movement and the screen is matched to make the corn kernels drag down.

The kneading action between the nail roller and the sieve removes the corn kernels from the corn cob. With the help of other machinery, the corn kernels and corn cobs are sent out of the body through two different outlets. The core is discharged from the tail of the machine, and corn shreds and dander are discharged from the air vent. Cyclic threshing, the cycle of filling-threshing-discharging the body is continuously performed. This kind of machine, the threshing efficiency is determined by the length and diameter of the drum, people can reasonably choose the appropriate corn thresher according to their threshing efficiency.

Corn thresher threshes are a kind of grain harvested in the field through mechanical milling, rubbing, separation, cleaning and other methods to obtain grain, one time or through auxiliary cleaning and other means to meet the storage requirements Work tools.

Corn thresher products can be divided into fixed and mobile (including traction and hanging) according to the power supply method; according to the crop feeding method, they can be divided into two types: full-feed and semi-feed; The structure can be divided into simple type, semi-duplex type, and duplex type. According to crop applicability, it can be divided into the rice and wheat thresher, corn thresher, soybean thresher, and other models. Generally speaking, stationary threshers are mainly small and household and mobile threshers are mainly large and medium-sized and commercial operations.

How to maintain corn thresher

1. Daily testing of thresher

(1) External overall inspection

Thoroughly clean the outside of the thresher, check whether all the fastening screws are loose, whether all parts are safe, and whether there is welding, cracking or deformation. The feeding inlet should be provided with a safety cover, the feeding plate should be provided with a safety warning sign, and the length should be not less than 30 cm.

(2) Inspection of trial operation

After threshing and rotation, check whether there is air leakage at the feed inlet, and at the same time check the machine for abnormal vibration, and perform full lubrication as required. Carefully observe for collisions, friction, and stagnation. Is there any abnormal sound? Use the power machinery to drive the thresher at a low speed, and observe the operation status of each part.

(3) Inspection of the input device

The conveyor chain must be inspected section by section, and if it is found to be severely worn, deformed, or cracked, it should be replaced. The tension of the feeding chain should be consistent from left to right. It is advisable that the middle of the chain length slightly touches the bottom plate. The main and passive axes of the conveyor chain should be parallel.

(4) Inspection of the clutch device

The safety clutch should be adjusted during work and use, check the wear of the wave tooth, and it should be replaced when the tooth height is worn away by 1/3.

(5) Inspection and adjustment of thresher

The rotation speed of the drum should be different for different threshing crops. General wheat 1500 rpm, soybeans, sorghum 800 rpm. The drum should rotate flexibly, without obvious shaft-to-axis movement, and the radial runout must not be greater than 1.5 mm. The amount of grain height wear of the corrugated rod should not exceed 50%, and the amount of wear of the working area of ​​the nail should not exceed 1/4 of the original size. At the same time, check the fixed condition of the rod or nail. The tightening torque of the bolt is in the range of 40-65 N · m; the deformation of the corrugated rod should not exceed 1 mm in total length. If deformation or crack is found, it should be replaced. Welding repair is not allowed. The threshing interval should be determined according to different crops. Adjust the inlet clearance first, and the clearance should be consistent from left to right.

(6) Inspection of grain cleaning equipment

Check that the screen frame must not be deformed, be welded or damaged, the screen surface should not be torn or blocked, and the slide should be smooth. The inclination angle of the screen surface and the position of the fan air baffle can be adjusted ideally according to the degree of grain cleaning. Grain-lifting, double-removing, and awn-removing devices can be adjusted according to the working conditions.

(7) Correctly adjust the threshing gap

The gap between the drum and the concave plate mainly depends on the structure type, technical status of the thresher and the condition of the crops to be removed. The principle of adjustment is: on the premise of clean removal, use a large gap as much as possible, so as to not only get good threshing quality, but also improve productivity, reduce energy consumption, and prevent the drum from blocking. Note: The gap is not adjusted once and for all. It should be stopped and adjusted at any time according to the requirements of crop type, variety, humidity, maturity, and threshing quality. The gap from the feeding inlet to the straw outlet is gradually reduced from large to small. The gap between the straw outlets should be uniform, otherwise, the threshing quality will be affected.

2.Maintenance of thresher

(1) Pay attention to the lubrication and maintenance of parts. The parts in the threshing machine must run at high speed during the working process. Therefore, each work must be kept in a good lubrication state, that is to say, lubrication is a must-do thing before threshing. Special attention should be paid to the bearing part of the threshing machine. Frequently grease and keep the bearings clean and lubricated. After the end of the operating period, the bearing should be disassembled and cleaned with diesel or metal detergent, and the grease should be replaced at the same time to keep it in good condition and prepare for future use.

(2) After the threshing is finished, the dust and debris inside the machine should be carefully removed; the paint that is peeled off during use should be re-painted as required; the desoldered and cracked parts should be repaired by welding.

(3) After the thresher finishes working for one day, after checking and cleaning, we must cover the whole body with a cloth to prevent rain and snow from entering the machine. Conditional can be stored in the library. At the same time, before the threshing machine is put into operation next time, the machine should be allowed to run for a few minutes, and the sound is used to judge whether the internal operation of the machine is normal and stable. If there is no abnormal sound, it can be put into operation.

(4) Do well in warehouse management. After the thresher operation period is over, the thresher should be cleaned thoroughly. Thoroughly clean the dirt, dust, grains, weeds and other debris inside and outside the thresher, check the nail rollers, bearings and other important components, choose a flat terrain, parked in the leeward, and put them in the house or storage shed if possible If it is not working for a long time, remove the motor and store it separately for storage. At the same time, the chain should be unloaded, cleaned with diesel oil, soaked in oil for 15-20 minutes after being dried in the shade, and then put back in place.

Precautions for using corn thresher

1. Precautions for thresher operation:

(1) Selection of speed

The speed of the thresher should not be too fast. It should be used at the speed specified in the instruction manual, and the speed cannot be arbitrarily increased. Generally, the dewheat is 28-32 m / s, the indica rice is 24-26 m / s, and the japonica rice is 26-30 m / s. If the speed is too high, it will not only take off quickly, but will also cause unfavorable situations such as serious kernel breakage, shortened machine life, and increased unsafe factors. Install a matching electric motor or diesel engine according to the requirements or the signs on the machine, and equip them with suitable pulleys. Be careful not to install them in the opposite direction. The fan cannot be reversed when the pulley is turned, otherwise the cleanliness of the kernel will be affected.

(2) Feeding amount selection

During threshing, continuous and uniform feeding is required. If the feeding amount is too large, it will cause excessive load on the drum, lower the rotation speed, reduce the depuration rate and productivity, increase the number of grains entrained in the stalk, reduce the threshing quality, and cause blockages and shutdowns in severe cases damage. The feed rate is too small, the productivity is low, and sometimes the removal rate is affected. The indicators of clean off, fast off, less broken, and low energy consumption are actually mutually restrictive. If it is to be cleaned well, the crushing rate will increase, productivity will decrease, and energy consumption will increase.

The operator should, according to the actual situation, with the close cooperation of the "hand", "eye" and "ear", the "hand" senses the dryness and humidity of the crop, feed more dry and less wet; Check whether the speed is normal, feed more if the grass is smooth, and feed less when it is not smooth; "ear" listen to whether the sound of the machine is normal, and feed the load loudly and low, otherwise feed more.

2.Precautions for the safe operation of thresher

Threshers must pay attention to the following ten taboos.

A bogey for poor storage. When the summer and autumn harvests are over every year and the thresher is no longer in use, the thresher should be thoroughly scrubbed and placed in the room for storage. It cannot be thrown on the ground or on the side of the field. The wind and rain will cause the parts to rust and damage, leaving Potential insecurity.

Second, do not overhaul before use. Before harvesting the summer and autumn grains, the threshing machine needs to be carefully inspected and repaired to see if the bolts are loose, whether the bars are intact, and if there are any problems with the transmission components. Find out the unsafe factors and eliminate them. Do not run with "illness".

Three bogey overload work. No matter it is powered by an electric motor or diesel engine, it must not be overloaded when working, otherwise, it is very unsafe.

Four bogeys move and install at will. The threshing machine and its powerful machine must be moved and installed by skilled professional technicians. When moving the electric thresher, the power must be turned off first, and the insulated wires must not be dragged on the ground to prevent the insulation layer from being worn out and causing injury due to leakage. The shutdown and start of the diesel engine should be checked by a professional before operating safely.

Five taboo safety devices are incomplete. The safety device on the thresher and its powerful machine must be complete. For example, the transmission belt must have a safety cover, and the motor must be grounded to ensure personal safety.

Six bogeys temporary piece together a threshing staff. People who use threshers should know some mechanical operation and safety knowledge and have practical experience. Don't assemble people temporarily, otherwise, accidents are easy to happen.

Seven bogey straw feeding uneven. When threshing in a threshing machine, pay attention to uniform feeding. The feeding amount is appropriate. Straws must not be fed in bundles, and mixed foreign matter cannot be fed with the straws. Otherwise, the parts will be damaged and the person will be injured. A person's arm must not reach into the feeding port to prevent being injured by a high-speed rotating bar or even interrupting the arm.

Eight bogey people are mixed. The number of people participating in threshing should be appropriate, not as many as possible. Too many people not only waste manpower but also easily lead to unexpected accidents.

Nine continuous operation time is too long. When summer and autumn grains are harvested and threshed, they often need to fight day and night. However, the duration of continuous operation should not be too long. Generally, after 5-6 hours of work, the machine should be stopped and rested, and the thresher and its powerful machine should be inspected for safety so that people can rest The machinery is maintained, otherwise, accidents are likely to occur.

Ten avoid using homemade and eliminated threshers. Some people make their own threshers or use obsolete threshers to save money. Compared with threshers that leave the factory after strict inspection, this type of thresher has poor safety performance and cannot be used.
