Corn threshing and silk removing device

Abstract

The invention discloses a corn threshing and silk removing device which comprises a box body, a threshing rolling shaft, a driving motor and a fixed frame for supporting the box body on the ground. A filter screen plate is arranged at the lower end of the box body; the threshing rolling shaft is arranged between the box body and the filter screen plate; both ends of the threshing rolling shaft are fixedly arranged on the fixed frame by shaft sleeves; a feed hopper is arranged at the upper part of the right end of the box body; a discharge plate extends to the outside of the fixed frame; a bellows is arranged below the discharge plate; a fan is arranged at the lower end of the bellows; the bellows is provided with a receiving plate extending outwards; both a rotating shaft of the fan and a rotating shaft of the threshing rolling shaft are connected and driven by an output shaft of the driving motor through a belt. The corn threshing and silk removing device overcomes the defects in the prior art, is reasonably designed and has a compact structure; threshing throwing hammers adopts a movable structure and springs are arranged between the adjacent threshing throwing hammers, so that the motion trail of each throwing hammer is of a spiral shape, which is more beneficial to corn threshing; when material are stacked, buffering can be carried out, stress impact is reduced and the service life of equipment is prolonged; meanwhile, the fan is arranged at the lower end of the box body, so that the corn threshing and silk removing device is convenient to timely carrying out sorting on corn kernels and corn silk and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a corn threshing and beard removing device. Background technique [0002] Corn is composed of corn cobs, corn kernels, and corn whiskers. After the corn is collected, it is generally necessary to peel off the corn kernels from the corn cobs. The peeling of corn kernels is labor-intensive. In the early days, it was mainly done manually. Some corn threshers peel off the corn kernels by rotating the threshing rollers. In the prior art, the hammer on the threshing rollers is fixed on the fixed shaft, and the resistance received during threshing is relatively large, and the corn cobs are easily broken, which is not conducive to In the later stage of recycling, after the corn kernels are stripped, the corn silk and corn kernels are together, and manual sorting is required again, resulting in low production efficiency. Contents of the invention [0003] The purpose of ...
