Radial-axial bi-directional asynchronous package-type bionic corn husker

Abstract

The invention discloses a radial-axial bi-directional asynchronous package-type bionic corn husker. The radial-axial bi-directional asynchronous package-type bionic corn husker comprises a peeling mechanism, a transmission mechanism, a rack and a feeding mechanism. The peeling mechanism is fixed in front of the upper part of the rack. The feeding mechanism is fixed behind the upper part of the rack. A peeling space is formed by the bottom of an axial peeling copying roller, the exterior of a variable copying press block, the upper part of a copying conveyer belt and the exterior of a radial peeling ribbed roller. The axial and reverse torque to corn ear is formed by the copying conveyer belt and the axial peeling copying roller, and the radial torque to the corn ear is formed by the variable copying press block and the radial peeling ribbed roller. The variable copying press block is capable of, according to the section diameter of the corn ear, automatically adjusting the positive pressure. A narrower space is formed by a directional feeding roller and a standing plate, and a larger space is formed by the directional feeding roller and an arc plate. While the corn ear is loaded to be rotated by the directional feeding roller, the corn ear is directionally captured and unloaded by using the change of the space geometry dimension. The radial-axial bi-directional asynchronous package-type bionic corn husker is capable of improving the peeling efficiency, and reducing the extrusion damage and collision damage of corn grains.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a radial-axis bidirectional asynchronous wrapping type bionic corn peeling machine. Background technique [0002] The corn peeling machine is the main equipment for mechanized harvesting of corn. Its function is to peel off the bracts wrapped on the surface of corn ears. According to the use environment of the corn peeling machine, it is mainly divided into independent type and vehicle-mounted type. The independent type peeling machine mainly uses the electric motor as the power source to peel the corn that has been harvested and dried. This type of machine is mainly planted in small fields and segmented. Applied in the harvesting mode; the vehicle-mounted peeling machine is mainly installed on a large self-propelled combine harvester, using the engine as a power source, to simultaneously realize the peeling operation during the corn field harvesting operation, and to transport material...

AI Technical Summary

Problems solved by technology

The working principle of the corn peeling machine is that the peeling element exerts friction on the corn bracts. When the peeling element rotates, the corn bracts are subjected to alternating friction; from the direction of the bracts, the existing peeling principle is mainly radial peeling. That is, the rotation axis of the peeling element is parallel to the axis of the ear of corn. Under this operating principle, it is difficult to cut off the connection force between the bract leaf and the root of the corn in the axial direction, resulting in unclean peeling and high power consumption for peeling

In addition, in order to improve the peeling effect of corn, in the existing peeling technology, multiple radial peeling rollers are usually added to apply friction to the corn bracts at the same time, but the corn peeling gap is fixed. It is difficult to apply effective peeling stress to the corn bracts in the gap, and it is easy to cause extrusion damage and collision damage to the corn kernels when the gap is fixed
