AI Technical Summary
Existing corn threshing equipment lacks a screening structure, causing corn cobs and kernels to fall mixed together, requiring secondary separation by manual labor or other equipment. This increases the complexity of the processing flow and labor costs, and lacks flexibility, making it difficult to adapt to diverse production needs.
A threshing device with a flow-diverting component was designed, including a channel assembly, a positioning mechanism, and a screen frame. It can automatically screen and separate corn kernels and corn cobs after threshing, and has two modes: separate discharge and mixed discharge. The mode switching is achieved through the meshing transmission of synchronous gears and racks.
It enables automated screening of corn kernels and corn cobs, simplifies the processing flow, improves the flexibility and adaptability of the equipment, reduces manual intervention, and adapts to diverse processing needs.
