Corn stubble digging and stalk-stubble smashing device

Abstract

A corn stubble digging and stalk-stubble smashing device comprises a stalk smashing device, a transmission system, a digging-type stubble cutting device, a stalk feeding beater, a power input device, a housing, a side board, a supporting plate, a cutter, a tubular shaft and the like. The corn stubble digging and stalk-stubble smashing device can be used in conjunction with a self-propelled or suspended corn combine harvester, or can be used in conjunction with a tractor singly. The profile modeling supporting plate can lead the digging-type stubble cutting device to dig up and cut off corn stubbles according to a certain depth, the stubbles and stalks are fed to the stalk feeding beater together under the action of the stalk feeding beater, and the stalks and the stubbles are cut up through a high speed revolution crushing cutter, so that stubble digging, stalk smashing and field return operation can be performed by one machine at the same time.

Description

technical field [0001] Herein, the present invention relates to a corn stubble stalk and root stubble crushing device, especially a corn stubble stalk and root stubble crushing device that can realize the functions of stubble starting, stalk crushing and returning to the field 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, the stalks have been generally returned to the field, and there are not many stubble removal operations, mainly due to the problem of mechanical equipment. 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 are operated separately to complete the field returning and stubble removal...

AI Technical Summary

Problems solved by technology

This type of machine basically puts the stalk returning machine and the rotary tiller behind the machine (the hanging type is placed at the rear of the tractor, and there are also self-propelled ones that place the returning machine in the middle of the machine), and there are tractor or combine harvester tires The serious problem of pressing rods is that the cutting effect of the stalks is poor and cannot meet the agricultural requirements. In order to improve the quality of work, especially the part of the stalks that are 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, causing a series of problems such as a decrease in the speed of the cutter and affecting the quality of the shredding.
