A device for returning corn stalks to field

Abstract

The invention discloses a device for returning corn stalks to the field, which comprises a front fixed frame, a hydraulic adjustment device is installed under the front fixed frame, a controller is arranged outside the front fixed frame, and a An elastic driving wheel drive device is provided, and a biaxial straw crushing and returning device is provided at the front center of the front fixed frame. Adjust the elasticity of the compression spring through the electric telescopic rod, so that the rolling wheel can rotate stably to provide power to the device. Through the action of the rolling wheel and the gear accelerator, the crushing shaft is rotated at high speed, so that the straw in the farmland is crushed and returned to the field. It effectively solves the problem of troublesome driving when the straw returning machine is in front; through the staggered and crossed distribution of the transmission gear and the two rotating gears and the straw returning blades, the straw is fully crushed, which effectively improves the crushing of straw Effect, so that the straw can be quickly decomposed.

Description

technical field [0001] The invention relates to the field of equipment related to farmland planting, in particular to a device for returning corn stalks to the field. Background technique [0002] Returning stalks to the field is a measure of fertilizing soil fertility and increasing production that is generally valued in the world today. It can increase fertilizer and increase production while eliminating the air pollution caused by straw burning. Straw returning can increase soil organic matter, improve soil structure, loosen soil, increase porosity, reduce capacity, and promote microbial activity and root development of crops. [0003] In the patent CN201610362137.0, a corn stalk returning machine adopts modern industrial machinery level and is equipped with ventilation device, camera, fertilization device, pushing down device, brake plate, PLC electronic control device, crushing device, air conditioning device, and fertilizer applicator , Ventilation device and air cond...

Problems solved by technology

[0005] The purpose of the present invention is to solve the above problems by designing a device for returning corn stalks to the field, which has the functions of fast straw returning to the field and less residual residue, and solves the troublesome driving problem when the existing straw returning machine is installed in front of the tractor. The problem is that through the staggered distribution of the straw returning blades on the double cutting shaft, the corn stalks can be fully crushed, and at the same time, the power is provided to the device through the movement of the tractor, which effectively avoids the drive mode caused by the installation of the device on the front of the tractor. difficult question
