Safe use of thresher：
(1) Due to the intense work of the threshing machine and the harsh environment, the personnel participating in the threshing operation must be educated on safe operation so that they can understand the operating procedures and common sense of safety, such as tight sleeves, wearing masks and protective glasses, etc.
(2) Before using the threshing machine, you must carefully check whether the rotating and swinging parts are flexible and free from collisions; check whether the adjustment mechanism is normal and whether the safety facilities are complete and effective; ensure that there are no sundries in the machine, and that all lubricating parts should be filled with lubricating oil.
(3) Before starting the threshing machine, the work site should be cleaned up, and some sundries unrelated to threshing should not be placed; children are prohibited from playing on the site to avoid accidents.
(4) The feeding should be uniform during work, and the wheat should be pushed directly into the drum, and it is not allowed to push the wheat into the drum with hands, forks or other tools; strictly prevent stones, sticks and other hard objects from being fed into the machine.
(5) The joint of the transmission belt should be firm; it is strictly forbidden to take off the belt or touch any object to the transmission part when the machine is running.
(6) The transmission ratio between the selected supporting power and the threshing machine must meet the requirements, so as to avoid damage to parts or loosening of fasteners due to excessively high speed and severe vibration of the threshing machine.
(7) The threshing machine cannot work continuously for too long. Generally, it will work for about eight hours. It must be stopped for inspection, adjustment and lubrication to prevent severe friction and wear, heat and deformation.
(8) Threshers are generally powered by diesel engines, and an anti-flammation cover should be worn on the exhaust pipe to prevent fires.
(9) If the threshing machine breaks down during operation, it should be shut down for maintenance and adjustment, and it must not be dealt with to
avoid greater failure.
Daily maintenance of thresher：
(1) After the threshing is completed, the dust and sundries in the machine should be carefully removed; for the place where the paint falls off during use, repaint the paint as required.
(2) Desoldering and cracked parts need to be repaired by welding.
(3) Pay attention to the installation of the grain bar. The small head (slope) should face the feeding direction, and the grain direction of two adjacent grain bars should be opposite to prevent the grain from moving to one end of the drum, resulting in uneven load.
(4) Tighten the threaded rod bolts according to the specified torque. Generally, it is tightened in 3-4 times; check whether each threaded bolt has a lock nut, because when the threshing machine is operating, the roller runs at a high speed, and the nuts are easy to loosen, and the quality of the threaded rod must meet the requirements, and other bolts cannot be used instead.
(5) After the thresher drum is repaired, static balance debugging should be done until the debugging is balanced.
(6) Check whether the shield cover of the threshing machine is firm, and replace the damaged one.
(7) The maintenance is complete, add a sufficient amount of lubricating oil to each oil filling point and lubrication point, and oil the thread of each adjusting screw to prevent rust; place the thresher in a dry and ventilated shed, and be careful not to put it on the thresher Put sundries on it to prevent deformation .
