Stubble collecting and returning machine

Abstract

The invention relates to the technical field of agricultural machinery and provides a stubble collecting and returning machine. The machine comprises a gear box, a tripod, a stander, a stubble collecting device knife pivot, a stubble collecting device knife bed, a stubble collecting knife, a stubble chopping knife, a returning device knife pivot, a returning knife bed, a returning knife, a fixed knife, a case and a copying sliding plate, wherein the gear box is mounted on the stander; the tripod is mounted on the stander by a suspension loop; the stubble collecting device knife pivot is horizontally mounted on the stander; the stubble collecting device knife bed is welded on the stubble collecting device knife pivot according to helix arrangement for mounting the stubble collecting knife and the stubble chopping knife; the returning device knife pivot is horizontally mounted on the stander; the returning knife bed is welded on the returning device knife pivot according to helix arrangement for mounting the returning knife; the case is mounted outside the returning device; the fixed knife is welded at the inner side of the front of the case; and the copying sliding plate is mounted on the case. When the machine works, the stubble collecting device collects the stubbles and throws the stubbles together with the straws into the returning device and the returning device crushes and returns the stubbles and the straws, thus realizing that the machine and the tools enter into the field once and carry out straw stubble collecting and returning operations simultaneously.

Description

Technical field [0001] The invention relates to a stubble-returning machine, in particular to a stubble-returning machine capable of realizing the functions of stubble starting and field-returning at the same time, and belongs to the field of agricultural machinery. Background technique [0002] At present, the removal of corn stubble is an urgent problem in autumn corn harvesting, especially when combined corn harvesting or conservation tillage techniques are used. At present, when corn is harvested, straw returning to the field has been widely used, and there are not many stubble removal operations, mainly due to mechanical problems. Even if there is stubble removal, the method of stubble removal after returning to the field is adopted, or the field returning machine and the stubble removal machine operate separately to complete the field returning and stubble removal operations, or the straw returning and stubble removal machine can be composed of a field returning machin...

AI Technical Summary

Problems solved by technology

This type of machine basically puts the straw returning machine and the rotary cultivator behind the machine (suspended on the tractor) at the rear of the tractor (there are also self-propelled ones that place the returning machine in the middle of the machine), and there are tractors or combine harvesters. There is a serious problem with the tire pressure bar, and the cutting effect of the stalks is poor, which cannot meet the agricultural requirements. In order to improve the operation quality, especially the part of the straw that is overwhelmed by the tires, it is necessary to use a high-speed returning motorized knife to remove the stalks from the soil. When it is picked up and shredded, it must cut the soil seriously, which not only causes serious power consumption, but also increases the slip rate of the transmission system due to the obstruction of the soil, resulting in a decrease in the cutting speed and affecting the shredding quality.
