AI Technical Summary
Existing grain cleaning machines tend to accumulate grains during transport, affecting the screening effect, and the drying process does not effectively promote screening.
The pretreatment device is designed, including an inclined feed box, a dispersing rod, a heating rod, and a fan. It disperses and dries the grain crops to ensure uniform distribution, and performs material separation and screening during the screening process. Combined with a vibrating screen and a dust collection device, it improves screening efficiency and drying effect.
It achieves uniform feeding and efficient screening of grain crops, improves drying rate and screening efficiency, reduces the impact of impurity adhesion, and keeps the environment clean.
