Master the correct use and maintenance of corn thresher

With the increasing development of agricultural mechanization, many countries and regions have achieved mechanization of corn harvesting. In particular, corn threshers are widely used in corn production operations because of their many advantages such as easy installation, high production efficiency, and high safety performance. Mastering the correct use and maintenance of corn threshers and troubleshooting methods has important practical significance.

working principle. After the corn kernels are mature, the link with the corn cob will gradually become loose. After the blades on the drive shaft of the thresher rotate and collide at high speed, they are very easy to fall off. In addition, the spiral structure of the blades can make the corn cob smoothly discharged, and the screen can The corn kernels are cleanly filtered, fully realizing the efficient and energy-saving performance of the corn thresher.

Safe use and maintenance

Prepare before use. One is to conduct a security check. Flatten the four feet of the corn thresher to ensure that the equipment is stable and strong and reduce vibration. At the same time, according to the instructions, check whether the rotating and swinging parts are flexible and without collision, check whether the adjustment mechanism is normal and whether the safety facilities are complete and effective At the same time, each lubricating part should be filled with a sufficient amount of lubricating oil. The second is to conduct a trial operation. After turning on the power, idle for 1-2 minutes, check whether the machine is operating normally, check for jams, collisions, and other abnormal phenomena. Only after everything is normal can the material be fed. The third is to choose the right place to work. The threshing machine operation site should choose a flat and open place, and pay attention to the natural wind direction. The exit should be consistent with the natural wind direction. Reliable fireproof equipment should be provided in the operation. The fourth is to do a good job of safety protection. The safety protection device installed on the thresher is designed to protect the personal safety of the operator and its related personnel, so it cannot be disassembled during operation or work. If it has been disassembled during maintenance, the machine must be reinstalled before operation or work. In addition, when the machine is working, it is necessary to operate in accordance with the relevant safety signs on the machine. The operators must wear compact clothes to prevent accidents caused by clothes or hair getting caught in the rollers or transmission belts.

Use and adjust. First, the feeding amount should be appropriate. If the feeding is intermittent, it will affect production efficiency. Too much feeding will cause overload operation, and even lead to motor damage and equipment damage. The second is to regulate the roller adjustment. Generally speaking, the drum speed is high, the removal rate is high, the crushing rate is high, the rotation speed is low, the removal rate is low, and the crushing rate is low; a High crushing rate. But in the specific drum speed and gap adjustment, we must also judge the dry and wet conditions of corn, adjust the speed and gap according to the moisture content of corn. The third is not a continuous operation. Normally work for about 8 hours to shut down to check, adjust, and lubricate to prevent friction, serious wear, and tear, heat generation, or deformation. The fourth is to stop decisively when a fault occurs. It is strictly forbidden to take off the belt when the machine is running or contact any objects with the transmission parts. The transmission ratio between the supporting power and the thresher must meet the requirements. If the thresher fails during the operation, it should be decisively shut down before maintenance and adjustment.

Maintenance after use of dust-free corn thresher. After the operation of the thresher, the maintenance can be carried out according to the following procedures: First, the dust and other debris attached to the machine should be removed in time, loose screws should be tightened and removed, and the transmission belt, conveyor belt, and chain belt should be removed. The oil stain on the transmission belt should be cleaned with soapy water, dried, and hung on the wall separately to prevent corrosion and aging. Secondly, check whether the threshing board cover is firm and replace the damaged one. Welding and repairing are required for de-soldering and cracks. When installing the grain bar, the small head (inclined surface) should be oriented toward the feeding direction, and the grain direction of the two adjacent grain bars should be opposite to prevent the grain from moving to the end of the drum and causing the uneven load. Finally, add a sufficient amount of lubricating oil to each oil injection point and lubrication point. At the same time, place the machine in a dry warehouse or factory shed. If possible, it is best to use sleepers to cushion and cover with oil cloth to prevent the machine from moisture and exposure. Or rain.
