Orientating, spike-picking and peel-stripping device for corn bionic harvesting

Abstract

The invention discloses an orientating, spike-picking and peel-stripping device for corn bionic harvesting. The orientating, spike-picking and peel-stripping device comprises an orientating mechanism, a spike-picking mechanism, a peel-stripping mechanism, a conveying mechanism, a clamping mechanism, a stem pulling mechanism and a rack, wherein the orientating mechanism is fixedly arranged on the upper part of the rack; the spike-picking mechanism is fixedly arranged above the middle part of the rack; the peel-stripping mechanism is fixedly arranged at the outer side of the middle part of the rack; the conveying mechanism is fixedly arranged below the middle of the spike-picking mechanism and the middle of the peel-stripping mechanism; the clamping mechanism is fixedly arranged below the middle of the rack; the stem pulling mechanism is fixedly arranged on the lower part of the rack; a stem pulling concave roller and a stem pulling convex roller are coupled with each other, so that stalks bear downward pulling force; a spike-picking concave roller and a spike-picking convex roller reversely rotate to realize spike picking; a left rotary orientating auger and a right rotary orientating auger reversely rotate for forming orienting thrust on corn spikes; and a left rotary peel stripping roller is matched with the spike-picking concave roller, and a right rotary peel stripping roller and the spike-picking concave roller are matched, so that orientating peel-stripping operation is completed. The orientating, spike-picking and peel-stripping device is high in spike-picking precision, high in peel-stripping efficiency and is less in spike loss.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a corn bionic harvesting and directional ear picking and peeling device. Background technique [0002] Ear picking and peeling are two important processes in corn harvesting. The existing corn harvesters mainly use the front header and the rear peeling machine to complete the above two processes respectively, which not only increases the cost of machinery manufacturing, but also leads to frequent contact between corn and machinery. The contact of parts will cause a lot of loss and damage, which will seriously affect the comprehensive quality of corn harvest. With the improvement of the mechanization level of corn harvesting, the requirements of corn planting mode on corn harvesting efficiency are increasing. At present, the following problems generally exist in the corn harvesting process: corn ears generally droop after maturity, and the existing ear picking devices cannot effectively ...

[0002] Ear picking and peeling are two important processes in corn harvesting. The existing corn harvesters mainly use the front header and the rear peeling machine to complete the above two processes respectively, which not only increases the cost of machinery manufacturing, but also leads to frequent contact between corn and machinery. Parts contact, resulting in a lot of loss and damage, which seriously affects the comprehensive quality of corn harvest

With the improvement of the mechanization level of corn harvesting, the requirements of corn planting mode on corn harvesting efficiency are increasing. At present, the following problems generally exist in the corn harvesting process: corn ears generally droop after maturity, and the existing ear picking devices cannot effectively exert force on them. , resulting in a large number of missing ears of corn; when the corn with high moisture content is directly harvested, the bracts are tightly wound on the ears, and the structure and installation position of the existing peeling device cause the bracts to hinder corn threshing; the columnar profile of corn causes it to be threshed Rolling randomly after picking, the direction of the ear is not uniform when it is fed into the follow-up operation device, resulting in uneven stress on the ear, resulting in a large amount of loss and damage
