(1)Adjusting the tightness of the conveyor chain of the elevator. Open the valve below the elevator and pull the chain by hand. The chain can move left and right on the sprocket. The tightness is appropriate. Otherwise, it can be passed through the upper shaft of the elevator. Move up and down to adjust: loosen the bolt on the elevator housing (one on each side), turn the adjusting nut with a wrench, and move the elevator up or down axially, and tighten the nut until it is adjusted. If the conveying chain is too loose, the squeegee will be worn prematurely; if it is too tight, the lower auger shaft will be damaged. (2) The tightness of the belt of the elevator should be suitable. If it is too loose, it will be thrown and the tight shaft will be damaged. (3) The volume of the grain tank is 1.9 cubic meters. When the grain is full, the grain should be unloaded in time. Otherwise, parts such as elevators may be damaged. (4) The bottom of the grain tank has a grain to feed the auger and the food flowing into the auger is contained. The flow rate is adjusted by the unloading speed adjustment plate. The choice of the gap between the adjustment plate and the bottom plate depends on the dryness and humidity of the grain and the impurity content of the grain. The opening of the food with high humidity should be smaller, and vice versa. These should not be too large in order to prevent the unloading of food too fast, resulting in damage to the unloading grain auger. Combine with unloading grain auger when unloading the grain, the engine When using a large throttle, and to empty the grain once before unloading, turn the unloading drum to the unloading position. If you do not go to the unloading position, unloading the food can easily damage the universal joints and other components. When the tube harvester is unloading food, it is necessary to let the grain flow first. When the gravity is reduced, the grain-unloading clutch is engaged again. It should be pointed out that this must be done, otherwise the components such as the auger will be damaged.
