AI Technical Summary
Existing impurity removal devices are ineffective at removing straw and grass clippings from grains and are prone to clogging stainless steel mesh cylinders, affecting the use of the devices.
An extended impurity removal structure was designed, which uses a servo motor to drive a stainless steel mesh cylinder to move inside and outside the impurity removal cylinder, and performs multiple screenings through a screen and vibrator. The stability of the mesh cylinder is improved by combining a cross pin and bearing structure to avoid clogging.
It achieves efficient impurity removal from grains, avoids clogging of the mesh cylinder, improves the efficiency and effectiveness of impurity removal, and ensures the cleanliness of the grains.
