Product Advantage
After the crops enter the threshing chamber, they are threshed by the drum hitting, rubbing, and twisting, and the grains are mixed with straw and debris. The sieve body (rear concave plate sieve) is responsible for the following tasks:

|
|
Screening out grains The threshed grains fall through the sieve holes (or gaps between the sieve bars) and enter the cleaning system below. | Throwing out straw debris Large, un threshed or straw debris is thrown out of the screen and discharged from the grass outlet. | Prevent grain carryover/running By using appropriate screen and drum clearances and sieve hole specifications, prevent grains from being carried out or mixed into straw discharge. The patent mentions that changing the gap can reduce the phenomenon of "carrying and running grain |

Product Uses
The sieve size matches the crop
Different crops (such as rice, wheat, corn, and beans) have different threshing conditions, and the width, gap, and type of sieve are also different.
When crop stems are thick, have high moisture content, or are severely lodging, large aperture and wear-resistant structures may be required; Fine screening can be selected for light crops to reduce damage
Product Operate Guide
Maintenance and replacement cycle
Regularly check whether the screen surface is deformed, cracked, whether the screen holes are blocked, and whether the screen body fits well with the drum.
If there is incomplete threshing, increased loss, or weeds/stems carrying grain, the status of the sieve body should be checked in a timely manner.
At the same time, check whether the fixed clips, U-shaped locks, locking pins and other accessories are loose
