Corn harvester

Abstract

The invention discloses a corn harvester, and belongs to the technical field of agricultural machinery. The corn harvester comprises a power system and a chassis operating system, the chassis operating system has an infinitely variable speed, the front end of an upper frame of a chassis is hinged to a corncob picking table, a main transmission shaft of a stripping machine is positioned on the front side of a main transmission shaft of a corncob elevator, a corncob uniform distribution device is mounted between the corncob elevator and the stripping machine, and a corncob box support and a first power device for driving a corncob box to turn over are positioned in the same vertical plane. The corn harvester is flexible in steering, small in turning radius and convenient to operate, corncob conveying flow is in Z-shaped rotation between the corncob elevator and the stripping machine by the aid of the corncob uniform distribution device, a body is maximally shortened, the corn harvester can be shorter than 7200mm and is particularly suitable for harvesting low crops, high in working efficiency and particularly applicable to harvesting corns in the central plain and wheat rotation areas, and gravity center distribution of the whole harvester is reasonable.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a corn harvester. Background technique [0002] Before the invention of the corn harvester, people used artificial methods to harvest corn, which was time-consuming and laborious. The corn harvester is a kind of agricultural machinery that is used to complete multiple operations such as ear picking, transportation, peeling, collection, and stalk returning to the field at one time when the corn is mature. [0003] At present, the peeling and returning corn harvesters on the market in the Central Plains have the following disadvantages: [0004] 1. The length of the large-scale corn harvester is long (7500mm-8100mm). Limited by the small plots in the Central Plains, harvesting requires multiple turns, which cannot give full play to its effectiveness and low work efficiency; [0005] 2. The small corn harvester has a short vehicle length (5500mm-6500mm) and is flexi...

AI Technical Summary

Problems solved by technology

[0004] 1. The length of the large-scale corn harvester is long (7500mm-8100mm). Limited by the small plots in the Central Plains, harvesting requires multiple turns, which cannot give full play to its effectiveness and low work efficiency;

[0005] 2. The small corn harvester has a short vehicle length (5500mm-6500mm) and is flexible in turning, but its performance is worse than that of the large corn harvester. It is obviously insufficient in field returning effect, power performance, and walking performance configuration, and there is no stepless speed change, so the operation is not good. Convenience, low work efficiency
