There are many straws in the grass, which is mainly caused by the poor matching of fan air volume, screen mesh number and screen vibration frequency. These are design defects that cannot be solved even after sale.
You can only try to increase the air volume and change the mesh of the sieve to a smaller mesh, which will improve it. However, if we change it, it may run out of food. Remember to look at the mesh of the sieve when you change trains next time. The smaller the mesh, the better the design, and the larger the mesh, the worse the design.
In order to prevent the grain from escaping, we can only enlarge the sieve hole, and the bigger the sieve hole, the easier it is to enter the straw. The general experience is that there is almost no straw in the grain collected by the sieve of 1.3- 1.4, and there is straw in 1.6- 1.8, and it is very dirty when it goes up to 2.0.

Precautions for use:
Semi-feed combine harvester is equipped with advanced automatic control device. When the machine appears in the process of operation, such as excessive temperature, full warehouse, traffic jam, poor lawn mowing, abnormal lubrication and control failure, it will warn the operator through the alarm and flashing indicator light. At this point, the operator must check the warning parts, find out the reasons, and then continue to operate after troubleshooting.
(2) Cutting the straw lying on the ground will cause great damage to the straw supporting mechanism and cutting mechanism, so it is not suitable for operation.
(3) It is easy to get stuck when working in paddy fields with too deep mud feet (15cm or more). Don't go to the field to harvest, but pick it by hand after harvesting.
(4) Do not use the high gear of the auxiliary speed control handle for harvesting, otherwise it is likely to lead to the failure of the combine.
(5) Rubber crawler should be protected in daily use. For example, when crossing a ridge higher than 10cm, straw or bridge boards should be laid on both sides of the ridge, and sharp turns should be avoided when walking on gravel roads.
