First, the cause of threshing is not clean: the feeding amount is too large or the feeding is not uniform; there is a threshing gap between the pattern bar and the concave plate; the rotation speed of the roller is too low; the grain is too moist. Adjustment methods: 1. Reduce the amount of feed, even feeding. 2. Correctly adjust threshing clearance. Replace worn parts should be replaced in time. 3. The pulley of the power machine and the pulley of the thresher should be reasonable. If the pulley slips and turns, the tension pulley should be adjusted to tighten the belt. 4. Straw over wet grain should be properly ventilated, then drying and then threshing. Second, the reasons for poor seed cleanliness: lack of air flow fan, mostly fan is too loose, forming a belt drive slip, causing the fan speed can not meet the design index, or due to the looseness of the fan pulley screw to form a pulley idling, can not normally drive the fan Rotation; too much crop stalk entry into the drum. Repair methods: 1. Check the tightness of the fan drive belt, too loose should be properly adjusted tension pulley, the pulley tension to the appropriate degree; if the fan pulley fixing screws loose, should be fastened. 2. Reduce the amount of feed or feed the gap correctly. Third, the excessive fragmentation of the seeds: the threshing gap is too small or the drum speed is too high; the feed is uneven or the grain is too dry or too wet. Adjustment method: 1. Check whether the threshing gap is correct, the minimum gap of general wheat threshing should not be less than 4 mm, and whether the matching of the roller pulley and the power pulley should be checked is reasonable and accurate. If something is wrong, it should be adjusted or replaced. 2. As far as possible to ensure uniform feeding, more dry cereal feed, humidity and feed. D. Excessive grains discharged from the dust outlet Cause: The amount of exhaust air is too large; the hole in the concave plate is blocked. Repair methods: 1. First check whether the fan speed meets the requirements, if not meet the adjustment, adjust the fan pulley diameter to check whether it is properly equipped. 2. Shutdown, power off, and clear plug holes in the wells. V. Causes of serious blockage: The grain is too wet and the amount of feeding is too large; the drum speed is too low; the drum pattern is damaged and causes the grass to wrap around; the concave plate is seriously worn or damaged; the feed chain is loose or the clamp gap is too large, causing the drum Too much grass. Adjustment methods: 1. Properly reduce the amount of feed, and keep the feed evenly. 2. Check if the power is sufficient or the voltage is too low and if the power is reasonable. At the same time, it is also necessary to check the power transmission belt tension and whether the belt slips and spins. 3. If the roller bar is damaged, it should be repaired in time. 4. Repair or replace the concave plate. 5. Adjust the tightness of the feed chain, and also check the tension of the suction fan belt and the fan speed.
