A Brief Analysis of Some Faults of Knapsack Combine Due to Unskilled Operation(2)
The feeding trough obstructs the working parts of the header and functions well, but if the feeding amount is too large, the trough will be blocked even if the header is not blocked. If the operator is in the harvest, he can stop when he finds that there is a turning phenomenon at the feed inlet of the header. If the operator is to continue to harvest after the phenomenon of the to-be-turned grass is in place, this failure can be avoided. In addition, the looseness of the conveyor belt and the power transmission belt can also cause blockages. The operator should also pay attention to the tightening of the rake teeth on the belt conveyor belt. If the rake teeth fall loose, the amount of grain conveyed will inevitably be uneven. In addition to the blockage, if the rake teeth are entrained in the threshing machine, it will happen. Larger faults will not only damage the pins on the thresher, but also knock back the top cover. Blocking of the barrel in order to minimize the possibility of blockage failure of the barrel, first of all, the medium and large throttles should be maintained during the operation; secondly, when the operator should pay attention to the amount of feed, the majority of the time when the amount of feed is small is mostly in the state of harvesting the fallen grain. At this time, the operator should pay attention to controlling the speed of advancement and use the lifting handle to control the header to evenly enter the grain. In addition to the failure of the drive belt or the large amount of feeding, the row of grass wheels for rowing the grass can produce the following problems. 1 When the stems of the crop are wet and tough, the straw can be transported without breaking the straw, so that the long stem will get caught in the wheel, and the longer the stem is, the longer the stem will be The more bars, until clogging occurs. 2 row of grass entrainment increased dramatically. The secondary phenomenon was caused by the more dead leaves of the crops and the moisture in the grain, which blocked the screen of the gravure screen. In particular, the screen holes near the end of the row of grass wheels blocked the most. If it is checked that there is a lot of loss in the entrainment of the grass, the drum cover on the thresher can be opened and the gravure screen can be cleaned. When a new operator and a new food-receiving person cooperate with each other, it is often easy to block the dragon. For example, when the machine harvested, the food-receiving staff did not prepare the sacks and blocked the grain outlets. As a result, the grain was not fed smoothly, and the grain was agitated by the dragon; if it was too full in the grain bag, or the bags were not replaced, It also caused a blockage.
