In the processing industry of grains such as soybean, corn, rice and the like, threshing is a necessary prerequisite for all deep processing means; taking corn as an example, the technology of rolling corn kernels from a core rod to process corn flour is ancient. Recently, with the development of the mechanical industry, mechanized corn threshing devices are gradually produced.
The corn thresher mainly comprises a roller, a concave plate, a sieve, a fan, a feeding hopper, a seed sliding plate, a spiral guide rod and the like. The corn ears enter the roller through the feeding hopper and are threshed under the impact of the high-speed rotary roller and the interaction of the corn ears, the roller and the concave plate. Most of the seeds and fine impurities removed from the corn kernels pass through the concave plate holes and are cleaned by air flow of the fan. The light impurities are blown out from the impurity discharge port, and the seeds slide out of the machine by the seed slide plate. The cob moves backwards along the axial direction of the roller, is discharged out of the machine through the surface of the vibrating sieve from an outlet at the shaft end, and partial grains carried in the cob leak down through the sieve holes and enter the grain sliding plate to slide out of the machine. Therefore, the impact, extrusion and friction of the roller on the corn ear in the rotating state are direct mechanical effects for realizing threshing.
