1. Slopes should be operated as far as possible to avoid cross-slope operation. When harvesting on long-distance slopes, the back of the sieve should be raised. Larger sieve holes should be used. The inlet opening should be reduced to reduce food loss; In the case of a long distance cutting downhill, the back of the sieve should be lowered.
2. The operating unit of windy weather should not run in the wind direction to prevent the unit from working properly; the air inlet on the side of the grain clearing organization should be adjusted to be smaller, and the air inlet on the leeward side should be enlarged. The purpose is to reduce the loss of blown grain and increase Clean grain quality.
3. The operation of low crops should be properly adjusted and modified for the headers and reelers. The height of the headers should be kept at a height of 15cm and the cutting knife should not eat soil. If the cutting is too low, the cutting knife will eat soil. It will speed up the knife wear, break teeth and damage, adjust the reel down and back properly for normal harvesting; increase the unit forward speed to ensure the normal threshing feed amount; follow the sowing direction for harvesting operations, can Reduce the strong vibration of the unit caused by the increase of the forward speed, and also reduce the harvesting loss.
4. Operation of over-dried and over-ripened crops. Adding canvas strips on the wood-turning wheel pressure plate to increase the buffering effect of the reeling wheel in the reeling and reduce the loss of grain; lowering the height of the reeling wheel so that the reeling wheel will not strike. The head of the crop was hit to reduce grain loss; the reel speed was reduced to reduce the number of hits on the cutting crop.
5. When the operation field of harvester is low in wet field, the driving device of harvester shall be converted into track-type or half-track type so as to harvest crops in time. When the depth of mud feet is large, increase the width of ground wheel of unit to enhance anti-skid ability. And expand the grounding area as much as possible to prevent the machine from sagging.
6. The operation of lodging crops should appropriately reduce the forward speed of the unit; correctly select the harvesting direction of the unit, and the direction of flight of the unit should be opposite to the crop fall direction (known as the undercut), or an angle of about 45 degrees with the fallen crop (called the side Cut); appropriate adjustment of the reel forward and downward to ensure smooth reeling and normal cutting.
The six major operating conditions of the combine harvester
The operation of the combine harvester must follow strict operating practices. When encountering special circumstances, it must be performed in accordance with the specific operating instructions.
