Common faults and solutions of combine harvester

The combine harvester is a kind of agricultural machinery that integrates harvesting, threshing and impurity removal. China is a traditional small-scale peasant economic operation, so mechanized agriculture started late, and most farmers do not understand some agricultural machinery and tools. I don't know how to solve the problem for a while, especially for more sophisticated instruments like the combine harvester. Let's introduce the common faults and solutions of the combine harvester.

First, nothing can come out of the threshing mouth.

The threshing mouth is the place where the grain is discharged after impurity removal, and under normal circumstances it will be combined with the function of bagging. Then if the threshing mouth does not produce the goods in other ways are normal, it is very likely that the threshing drum is blocked. The reason for the blockage may be that there are too many weeds in the drum, which seriously hinders the rotation of the drum, so that the engine does not move the roller.

Solution: at this time, it is best to stop the machine in time, then remove the debris inside the drum, and then appropriately increase the distance between the roller and the wall. When starting again, the harvest speed should be reduced to avoid being caused again by too much influx.

Second, accumulate grain before cutting the table

The accumulation of grain in front of the harvester is the entrance after harvest, and carelessness here can easily lead to the accumulation of harvests. There are two general reasons, one is the harvest speed is too fast, the entrance can not be swallowed in time, resulting in intertwined accumulation. Second, the distance between the pusher and the entrance is large, so that the pushed items can not completely enter the opening, forming residues and causing accumulation.

Solution: at this time, the pushing distance of the pusher should be properly adjusted to make the pushing items closer to the entrance.

Third, a large number of missed cuts

Missed harvesting is a common problem in combined harvesting, that is, there are more unharvested items left in the places where the harvester passes, or the harvesting is not complete.

Solution: first check whether the blade is sharp and see if it is caused by the gap. Secondly, check whether the scope of the blade harvesting is comprehensive, and there is a blind area that can not be harvested. Check whether the height of the blade is so high (low) that it cannot be harvested, especially when harvesting in the direction of grain dumping.

Fourth, threshing is incomplete and there are many sundries.

In particular, this problem should attract everyone's attention, otherwise it will be a more tedious thing in the later stage.

Solution: the first thing to solve this problem is to check whether the items in the thresher have been damaged. The bending of some small parts or the concave wall may cause this phenomenon, and if so, replace them in time. If the equipment is in good condition, it may be that the roller rotates faster, so that the harvest can not hit the threshing plate, and the speed of the roller can be reduced appropriately or the distance between the roller and the threshing plate can be reduced.

Fifth, the Arbor is broken and detached

Harvesting blades are extremely prone to problems during harvesting. They can break off because they are not fixed during harvesting, and they can also be damaged by some prominent hard objects in the field that people do not notice.

Solution: when it is useless every day, we should take good care of the blade to avoid its rust and so on. Secondly, we must carefully check the fixed screw before each harvest. It is best to twist it to see if it is loose. When harvesting, it is best to choose a place with flat terrain, or you can check the protruding place around the land in advance so that you can have a number in mind to avoid bumping into it.

VI. the harvest lies in front.

The front of the harvest is the most common problem when harvesting rice and so on, which is mostly caused by the low harvest speed.

Solution: at this time, it is necessary to increase the harvesting speed appropriately, lower the cutting tool a little bit, and tighten the belt to ensure the rotation speed of the blade and to ensure a better harvest.

The above is a brief introduction of the common faults and solutions of the combine harvester by the soil flow network. we should pay more attention to these problems when we operate, and it is best to check and clean up after a certain range of harvesting, so that we can run the machinery more effectively.
