In addition to the proper use of the corn thresher, in addition to following certain principles of use, we must remember that Mo stepped into the wrong area of use. The following are six misunderstandings used by threshers for reference.
(A) poor maintenance
The thresher should be overhauled immediately after it is used up and kept in a safe place so that it can be reused next time or next year. However, after being used up, they can be placed on the sidelines, grounds, or courtyards, and exposed to wind, sun, and rain. Many parts are rusted, causing self-destruction or difficult maintenance before the next use. Some even know that there is something wrong, and they don't overhaul or schedule. They think that it will be used for a short time anyway. Therefore, accidents such as loose screws, broken bars, and falling down of the pulleys often occur, which hurts people. Some even "exploded".
(II) Using obsolete models
Some of the small and simple grain-type threshers produced in the early years, although simple in structure and high in efficiency, they have poor safety and frequent injuries. It has been phased out (such as 5TJ-110), and manufacturers do not produce complete machines or accessories. But some owners have a chance to spend money on new machines. As everyone knows, accidents often occur in this situation.
(C) unfamiliar operation
Some places have changed the practice of using an experienced manipulator to uniformly control the threshing machine and threshing in the past, but each family has its own battle. Many operators do not understand mechanical principles and lack of safety knowledge and think that everyone who threshes will use it for only a short time in a year. They are not willing to spend time on training courses. Even one household is organic and operated by everyone in the home and neighborhood. Encountered situations, I do not know how to deal with, repeated accidents.
(four) energy dispersal
People are easily fatigued during the autumn harvest. It is especially prone to sleepiness at night, coupled with poor lighting, which distracts energy and causes accidents. Others are feeding while watching the children. They are not focused and their hands are easily caught by the roller.
(V) Inadequate safety facilities
The drive belt has no protective cover, and people are injured near it; there is no fire extinguishing device on the diesel engine, and Mars spurts out, causing a fire; there is no fire extinguisher or sand, water and other fire extinguishing facilities on the side of the field. Once the fire occurs, it is passive.
(Six) with many hands
When feeding wheat straw, there is no major person to talk about safety knowledge and no unified command from adults. Adults, women, and children all come together. Some wheat straws are fed in groups, and some straws have foreign objects or tools in the center, which cause damage to the thresher. Some hands went too deep and were injured by rollers.

How to fire corn thresher
Corn thresher harvesting season happens to be the hot summer, so fire prevention measures are more important.
1. Do not run overload for a long time during operation. When the water tank is turned on and the engine is overheated, it should be stopped and cooled down.
2. Frequently check the tension of the corn thresher conveyor belt and the sturdiness of each component. Fill the bearing parts with lubricating oil according to regulations, remove the stalks around the bearing in time, and avoid mechanical friction and overheating to avoid causing fire.
3. Check the electrical equipment frequently to see if there is any looseness in the circuit wires and whether the equipment is damaged.
4. Remove mechanical faults on the site and move to a safe place outside the site; repair large-scale machinery that is not easy to move, first remove the combustibles around the body; when welding, add a protective plate and set up a special person to ensure safety.
5, equipped with fire appliances. Wear a fire safety helmet; equipped with a fire extinguisher.
6. When refueling the corn thresher at night, wear a flashlight or work light on the car. It is strictly forbidden to use open flame lighting. Do not start the motor by fire.
7. Persons entering the field are not allowed to bring on fire. It is strictly forbidden to use open flames or electric welding at the harvesting site. It is not allowed to set off firecrackers.

Advantages and disadvantages of vertical rice mills
Advantages of vertical rice mill
1. Gravity has no effect on the centrifugal acceleration of rice grains, and the speed of rice grains and the pressure in the white milling chamber are uniform;
2. When feeding, gravity produces a driving force over the full length of the white milling chamber, and the density of rice grain fluid is relatively uniform;
3. The number of rice knives is large, the material is soft, and the adjustment is convenient.
4. The combined effect of the above 3 points can reduce the broken rice rate;
5. The white roller adopts a series of grinding wheels, which can be replaced and adjusted locally when worn, which improves the service life of the roller;
6. The bran layer is smooth and smooth.
Disadvantages of vertical rice mill
1. High requirements for keeping the operation smooth. During the manufacture and installation of the rice mill, the axis of the white roller must be kept vertical with slight errors. Even with a completely balanced white roller, the center of gravity deviates from the vertical line to generate an unbalanced force;
2. The bearing bears a combination of axial and radial bidirectional forces, which requires high performance, manufacturing and assembly quality of the bearing;
3. The volume and weight of the unit output are relatively large. The use of gravity as the axial driving force is limited, and the axial flow velocity of the ice flow is small. In the case of the same feed material as the horizontal rice mill, the diameter of the white roller must be increased to increase the annular cross-sectional area of the white roller. As the volume and weight of the rice mill increase,
4. It is inconvenient and time-consuming to disassemble the sand roller in the vertical direction of the top of the rice mill;
5. Soft rice knives wear quickly and have large quantities, increasing maintenance costs;
6. It is difficult and unreasonable for two white rollers to be coaxially or non-axially combined on a rice mill.

Advantages and disadvantages of horizontal rice mill
Advantages of horizontal rice mill
1. Smooth running. The bearing only bears the radial force, and the bearing stress and the whole machine torque produced by the unbalanced force are small. Horizontally installed white rollers have low requirements for manufacturing and assembly; the technical requirements for corresponding structural parts are general;
2. The volume and weight of the unit output are small. Due to the large axial driving force and the large grain flow rate, under the same feed material flow condition as the vertical rice mill, the diameter of the white roller and the annular area of the white milling chamber are small, and the whole machine has a small volume and weight Lighter, combined with lower manufacturing technology requirements and lower cost;
3. It is convenient to disassemble the sand roller in the horizontal direction of the rice mill, saving time and effort;
4. The rice production rate is high, and the spiral groove makes the density of the rice grain fluid uniform over the entire length of the white milling chamber, the rolling motion is good, and the parts on the rice grain are evenly milled;
5. It is convenient and reasonable to combine the two white rollers coaxially or in different axes in a rice mill.
Disadvantages of horizontal rice mill
1. Gravity affects the centrifugal acceleration of rice grains, which causes a difference between the upper and lower parts of the whitening room, and affects the uniformity of the whitening degree;
2. The number of rice knives is small, the material is hard, and some are not easy to adjust. For example, the fixed rice knives in the middle and lower parts need to be stopped and adjusted. Although the steel rice knives are wear-resistant, they are easy to damage the rice grains and increase the rice breaking rate.
3. Bran easily accumulates in the upper part of the whitening room;
4. Spiral grooves need to be manually repaired after being worn. The quality of the repair varies from person to person. The grinding rollers are assembled in $ 35 sections. After abrasion, they cannot be interchanged or partially exchanged. The maintenance cost is high.

Understand the preparations before using the peanut sheller
In recent years, with the rapid development of the economy, in recent years, agriculture is trending towards the development of mechanized operations, which not only reduces the burden on farmers but also improves work efficiency. And peanuts account for a large proportion of agricultural production, making peanut shellers become one of the most popular machinery for farmers. So what preparations need to be done before use? Let ’s take a look at it together.
1. Before use, check whether the peanut sheller is placed stably, and ensure that the peanut sheller is placed smoothly to meet the requirements of safe operation.
2. Then check whether the fasteners of the machine are tightened, whether the rotating parts are flexible, and whether there is sufficient lubricant in each bearing. Make sure that the fasteners are moderately tight and the rotating parts are flexible.
3. Also check whether the fasteners of the machine are tightened, whether the rotating parts are flexible, and whether there is sufficient lubricant in the bearings. Make sure that the fasteners are moderately tight and the rotating parts are flexible. Before turning on the power, you should idle a few times to see how flexible it is. If you find an impact sound, you should find out the cause in time, and then turn on the power.
4. Before use, you must connect a 380-volt three-phase power supply and check the power supply voltage. In order to ensure the safety of the operator, if the three-phase power supply is not connected during production, the housing of the motor must be grounded to protect the motor. The shell is connected with a lead and a ground.

Peanut sheller uses two elements
With the improvement of living standards, the use of peanut shellers is becoming more and more frequent, but most people are not clear about its precautions and maintenance methods, which leads to a reduction in the life of the machine and frequent failures. For this reason, taizy machinery is here. Let's explain it.
Inspection and debugging
Before production, the components of the machine need to be inspected, as well as the idling test. During the pressure test of the whole machine, the test pressure is 1.25 times the working pressure. Check that the piston is extended to the maximum working stroke, and stabilized for 15 minutes. The drop value of the pressure gauge reading shall not exceed 4% of the test pressure; all oil circuits shall be free of leakage; after all pressure is removed, the pressure gauge pointer returns to the '0' position, the parts shall not be damaged, and the drawbar shall not have any significant Deformation, no jamming of moving parts. Perform a reliability test on the safety valve, adjust the safety valve to the working pressure (upper left +5, lower left +1) MPa, test continuously for 5 times, the needle valve is sensitive to open and close, and the pressure gauge reading should not be lower than after each trip. Rated working pressure.
Maintenance
The pressure oil in the oil pump should be filtered to save water and irrigation. The concentration should not be too large. It is recommended to use rapeseed oil, soybean oil, and peanut oil. It is prohibited to use gasoline, kerosene and other flammable fuels. The fuel tank must be kept clean, and the fuel tank should be cleaned and replaced with new oil every 3 months or the oil in the tank should be taken out and filtered before use. The impurities in the oil will cause the oil pump to wear and cause the oil circuit to be blocked, affecting normal operation.
