What is the reason for the grain leakage of harvester? How to solve the problem of grain leakage of harvester?

If the wind force is too large, the air inlet adjusting plates on both sides of the fan can be appropriately lowered to reduce the wind force. If the wind direction is wrong, you can adjust the wind direction by adjusting the wind direction adjusting plate. The grain leakage of harvester mainly occurs in three parts. The first part is the grass discharge port of the drum, which discharges too many particles and belongs to entrained particles. The second part is the food leaked from the middle of the sieve box in the clean room. The last place is the end of the sieve box, where the wheat bran is discharged. Now let's take a look at them one by one. Let's talk about the problem of particles escaping from the suction pipe of the drum, which leads to too many particles. There are four main reasons for this. Otherwise, the supporting force of the vehicle will decrease, resulting in poor feeding and particle entrainment. Whether the belt and roller belt are tensioned in place. Harvesters sometimes leak water.

If the tension is not in place, the speed of the drum will decrease, leading to entrainment. We can adjust the belt tension in time. The rotating speed of the axial flow drum is too low or the intaglio under the drum is blocked, which leads to the reduction of the separation area. At this time, it is necessary to increase the drum speed and clean up the excessive feeding. At this time, it is necessary to reduce the forward speed of the machine or increase the stubble clearing height to reduce the load. Let's talk about the problem of water leakage in the middle of the screen box. Because I have a lot of knowledge, I can like it+collect it, which avoids that I can't find it if I want to see it later. The main reason for particle leakage in this part is that the shielding on both sides of the screen box is damaged and the sealing is not tight. It is necessary to replace the shielding sealing plate of the screen box in time.

There are four main reasons for this. The size of the screen is very small, and the opening of the screen hole can be appropriately increased. The air volume is too large and the particles are blown out. The solution is to reduce the opening of the air door. Pay attention to the adjustment of air volume and the opening of the screen here. When the rotating speed of the longitudinal roller is too high, the cleaning load increases. At this time, it is necessary to reduce the speed of the drum. The last point is that the feed is large, the wheat is thick and the yield is high. At this time, the forward speed should be reduced, the stubble height should be increased, and the feeding amount should be reduced. The above points are the main causes of food leakage, so it is necessary to find the specific part of food leakage accurately in order to find a solution quickly.
