Wheat combine harvester operation essentials

Correct operation of the combine harvester can avoid machine failures and improve work efficiency. First, start to increase the throttle steadily, so that the harvester reaches the rated speed, and then cut. When obstacles turn and reversing, you must raise the header, reduce the throttle, and stop cutting. Second, the operating speed Under normal circumstances, the use of II block operation. When the wheat is dense, the plants are large, and the yield is high, the I block operation can be adopted; when the wheat growth is sparse, short, and the yield is low, the III block operation can be adopted. In the morning and evening when there are fog dew and rain after the operation, due to the damp wheat stalks, the speed should be lower. Before and after noon, the wheat stalks can be dried at a higher speed. Third, the reel speed in general circumstances, its circumferential speed should be 1.5 times the unit forward speed, not only to ensure that the reel can effectively cut the wheat to the cutter to cut, but also to avoid the reel speed is too high The loss of wheat grain was caused. Fourth, cutting the extent of the load allows the situation, should try to full or nearly full-scale work, at this time the highest operating efficiency, but do not produce missing cut to reduce harvesting losses. 5. The height of the cutting table is conducive to post-cutting tillage and sowing operations. Cutting shall be as low as possible. This is also an important measure for harvesting the lodging of wheat, reducing ear cutting and ear leakage, but the height of the cutting table must not be less than 6 cm to avoid cutting the soil. Accelerate cutter wear. According to the requirements of operational quality standards, the maximum cutting height must not exceed 15cm. 6. One of the walking routes adopts clockwise rotation and harvesting; the other is counterclockwise rotation and harvesting. In order to facilitate the unloading of grain on the left side, the use of clockwise rotary harvesting has been adopted. For lodging of wheat, harvesting should be reversed or laterally to reduce the loss of wheat harvest.
