In the summer harvest season, there are thousands of mills competing for food and swallowing gold. In the self-propelled combine harvester, there will always be a few “lazy machines†singing unhappily, and other units will harvest 7-12 acres per hour, while “lazy†machines can only harvest 7-8 acres a day. Wheat straw turmoil. The reason for this is mostly the misuse of misuse. Now introduce to you the correct use of operating points:
First, enter the field and turn it around. Before the combine harvester enters the field, it should first smoothly engage the threshing cylinder clutch to slowly rotate the working parts; then place the header and reel wheels to the working position; then select the forward gear according to the growing trend of the wheat ( Generally choose low gear), and make the engine cut at the rated speed, avoid using small throttle cut. When turning in the field, it is necessary to raise the header and reduce the forward speed, but the engine speed cannot be reduced.
Second, to operate a good anti-blocking handle. The self-propelled combine harvester is provided with an anti-blocking handle that increases the gap between the exit and the entrance of the intaglio plate in order to prevent the rollers from being blocked during harvesting. If the blockage of the roller is not completely blocked before harvesting, the deceleration operation is prevented. Handle, then raise the concave plate immediately after the blockage to prevent loss caused by the loss of the net.
Third, to use threshing and unloading food handles. The two handles are the clutches that control the threshing and unloading, respectively, so they are slow and smooth when engaged, and they are quick and thorough to separate. In particular, it should be noted that if there is any obstruction during the unloading of food, it cannot be forced to start. Instead, it must first remove some food from the food unloading mouth, and then press the unloading handle to remove the remaining food in the granary.
Fourth, put the hydraulic lifting handle. When operating the header and reel, it is necessary to move one step to the desired position. When in place, return the handle to the neutral position in time and secure it.
Fifth, pay attention to obstacles in the field. When driving the combine harvester in the field, it is necessary to closely observe the presence of obstacles in front of it to prevent the knife from cutting into hard objects to damage the blade guard or bend the knife bar.
Sixth, it is necessary to solve the common "small problems" at any time. For example, if the cutter is clogged, the gap between the moving and fixed cutters is normal, the matching position is “centeredâ€, and the bolts and arbors are not deformed. Because there are too many weeds in the field, they can be eliminated as long as they are properly increased. In the case of grass clippings in front of the knife, if the reel is not high or forward, it is mainly crops that are short and sparse, dry and slippery. The augers cannot catch the straw, but gather before the cutting knife. At this point, the vehicle should be parked first, and the piled crops should all be fed from the header of the auger. Then, the height of the cutworms should be reduced as much as possible, and then the machine should be turned on. Naturally, there will be no grass in the front of the cutting knife. Again, if the cutting head agitates the blockage, the current forward speed is not too fast, and the tension of the floating slider spring is moderate. The main reason is that the clearance between the spiral blade of the header pushing device and the bottom plate of the header is too large, causing the pushing operation. , Make the cut crops clog up in front of the auger. At this point, only the gap between the spiral blade and the header plate is adjusted to about 10 mm, and then the failure of the header agitating block is eliminated by using a file to pull out the teeth at the edge of the blade.
