Semi-automatic corn threshers are commonly used small and medium-sized agricultural machines by farmers. They involve manual feeding, mechanical threshing, and automatic separation of kernels from cobs/impurities, making them far more efficient than manual labor. They are suitable for families, small farms, and scenarios where continuous automation is not required.
Feeding: Corn cobs (with or without husks) are manually fed into the hopper.
Threshing: The corn enters between the drum and the concave plate, where high-speed rotating spikes and teeth strike and knead the kernels, causing them to fall off.
Separation: Kernels fall through the sieve holes, while the corn cobs are discharged from the rear. Lighter impurities are blown out by a blower.
Collection: Kernels are directly bagged/placed in a bin; corn cobs are collected separately.
