The safety device of the rice sheller should be complete, and the part of the transmission must have a safety shield. The motor and the thresher should be matched. It is strictly forbidden to operate without training. The number of people should be appropriate, the division of labor should be clear, and the feeding amount should be uniform and appropriate. It is not allowed to push the wheat into the drum with forks, wooden poles and other tools. The human arm must not protrude into the feeding port to prevent it from being injured by the rotating drum.
Common faults of rice sheller and its elimination methods:
1.Unsaturated threshing: common reasons are low drum speed, large threshing gap, large groove and concave plate wear, and too much feeding; elimination method: increase the speed, adjust the gap, replace the concave plate, reduce the feeding amount;
2.Unclear separation: common reasons are insufficient air volume or incorrect wind direction. The rice sheller is damaged or the gap is too large and the grain is too wet. Removal method: adjust the air volume to the proper position to check the machine mesh hole and adjust the gap;
3.The drum is clogged: the reason is that the grain is too wet and the feeding amount is too large, and the rotation speed of the drum is too low. The transmission belt is slippery; the elimination method: turning the crop, feeding evenly and continuously, appropriately increasing the rotation speed, and tightening the belt tension;
4.Grain breakage: the reason is that the threshing gap is too small, the drum rotation speed is too high, and the feeding grain is uneven; the elimination method: appropriately adjust the gap, reduce the rotation speed, and feed continuously evenly;
5.The drum of the rice sheller has noise: the bolts are loose, the concave plate is deformed, and the threshing gap is small; the elimination method: tightening the screws, repairing the concave plate, adjusting the gap;
6.The motor of the rice sheller is overheated: too much feed causes the load to be too large, the ventilation is poor, and the heat cannot be dissipated; the elimination method: reduce the feed amount, remove the debris around the motor, and check the wire and voltage.
