Four-wheel driven corn harvester with middle stubble machine

Abstract

The invention discloses a four-wheel driven corn harvester with a middle stubble machine, which belongs to the field of agriculture. The corn harvester comprises two front wheels, a gearbox driving axle, transmission shafts, the stubble machine, a rear driving axle and two rear wheels, wherein the transmission shafts comprise a front transmission shaft and a rear transmission shaft; a transmission shaft carrier gearbox is mounted between the front transmission shaft and the rear transmission shaft; the transmission shaft carrier gearbox consists of an upper transmission gear and a lower transmission gear; the upper transmission gear and the lower transmission are in chain transmission; the lower transmission gear is fixedly connected with a first transmission shaft; the first transmission shaft is connected with the front transmission shaft through a universal joint; the lower transmission gear is fixedly connected with a second transmission shaft; the second transmission shaft is connected with the rear transmission shaft through another universal joint. The corn harvester has the characteristics that the stubble machine is solidly fixed, high in dynamic property, and the like, and the straw crushing effect is good, so that straw turnover is facilitated. The corn harvester is scientific in design, reasonable in structure, simple and convenient to operate, labor-saving and low in cost, and is applicable to popularization and application in corn harvesters.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to the transformation of a corn harvester. Background technique [0002] The corn harvester is an operating machine that uses machinery to complete corn stalk cutting, ear picking, peeling, threshing, straw treatment, and rotary plowing of the land after harvesting when the corn is mature, according to its planting method and agronomic requirements. One of the important links, straw processing has gone through the stages of simple straw processor, harvester front returning machine and post returning machine. If the corn harvester and the straw processing machine operate separately, it will not only be time-consuming, but also increase the amount of manual work, which has gradually been eliminated from the agricultural stage. Among the existing corn harvesters, most of them are front returning machines or rear returning machines. And in the existing corn harvester, m...

Problems solved by technology

[0003] In order to overcome the defects of the above-mentioned prior art, the present invention provides a four-wheel-drive corn harvester with a center-mounted field-returning machine, which can not only drive four-wheels but also install a straw-returning machine in the middle of the frame. In this way, the perfect combination of the harvester and the straw returning machine is realized, which makes up for the shortcomings of the front returning machine and the rear returning machine, and also makes up for the lack of four-wheel drive.
