Adjustment method for "poor working condition" of combine harvester

uneven feeding is easy to generate strong current interference if it is not well arranged. Weak current causes: the position of the reel is too far away from the feeding auger of the header, the distance between the auger blade in the middle section and the bottom plate is too large, the distance between the feeding key and the telescopic tooth tip is inconsistent, and the crops are lodging or wet. Adjustment method: 1. On the premise that the spring teeth do not touch the cutter, the reel should be moved back as far as possible. 2、 Repair the feeding auger blade of the header to restore its height to the normal value. 3、 The distance between the feeding chain and the telescopic tooth tip shall be kept within cm. 4、 The spring length of the safety clutch of the header feeding auger shall be appropriate, and it can be separated in time when the feeding resistance is too large

causes of conveyor blockage: the conveyor belt is not tensioned enough or deviates, there are many sundries in the conveyor, and the grain stalk is wet. Adjustment method: clear the blockage and tension the transmission belt. When it is confirmed that the belt is worn and the transmission power is insufficient, it shall be replaced in time. If the wheat straw is too wet, reduce the cutting width or harvest it after the wheat straw is dry

cause of clogging of threshing drum: the drive belt is too loose or the feeding is uneven. Crops are thick and stems are wet. Adjustment method: 1. Tension the transmission belt. 2、 Control the feeding amount of header. 3、 Operate with large and medium oil valves. 4、 Select mature and dry crops to harvest or improve the stubble

reason for unclean threshing: crops grow well and advance too fast. The current development status of the domestic plastic machinery industry in the threshing department is that the gap between the bar and the concave plate is too large and the speed is low with low independent innovation ability and few high-grade and personalized special varieties. Adjustment methods: 1. Control the forward speed, and control the cutting width of Haomai field within 2/3. 2、 Adjust the threshing clearance of the thresher, and replace the severely worn parts in time. 3、 Tension the wheel belt of the threshing part linked by the power machine

there are many reasons for grain loss in the field: the wheat is too mature and the straw is too dry. Large opening of threshing part tile screen. Adjustment methods: first, select mature and appropriate fields to harvest. Its market sales are increasing at a rate of 16% every year. 2. Reduce the clearance between threshing tiles and sieves. The opening of the upper sieve is not more than 2/3, and the opening of the lower sieve is generally not less than 1/3. 3、 When the thresher reaches the ground, the header shall be raised quickly, and the remaining wheat in the threshing trough shall be sent with a large throttle. Generally, the structure and working state of the original machinery and equipment are not changed, and the quasi grain loss is maintained at about 5%. (end)
