Field machine for straw smashing and stubble cleaning through biaxial reverse rotation

Abstract

The invention relates to field of farm machinery and particularly relates to a field machine for straw smashing and stubble cleaning through biaxial reverse rotation. The field machine comprises a rack assembly, wherein a transmission shaft is arranged on the rack assembly, a large belt wheel is arranged at the outer end of the transmission shaft, a stubble cleaning knife shaft and a rotary blade shaft are arranged behind the transmission shaft, a small belt wheel is arranged at one end of the stubble cleaning knife shaft, the small belt wheel and the large belt wheel are in transmission linkage, a driving wheel is arranged at the other end of the stubble cleaning knife shaft, a rotary blade knife shaft large belt wheel is arranged at one end of the rotary blade knife shaft, the driving shaft and the rotary blade knife shaft large belt wheel are in transmission linkage, a stubble cleaning blade is installed on the stubble cleaning knife shaft which is provided with a rotary blade, and a levelling roller is arranged at the rear end of the rack assembly. According to the field machine, after crops are harvested, residual straws, weeds and stubbles are subjected to smashing, burying, rotary tillage, and covering by soil at a time, land is flattened so as to be beneficial to mechanical sowing at next season, and meanwhile, addition of devices is not needed. The field machine is simple in structure, good in operation efficiency and strong in adaptability.

Description

[0001] (1) Technical field [0002] The invention relates to the field of agricultural machinery, in particular to a straw crushing double-axis reverse stubble removal and returning machine. [0003] (2) Background technology [0004] At present, the stubble removal and returning machine used by farmers is mainly to crush the stubble and straw left after the crops are harvested. It affects the quality of sowing. Therefore, when cultivating in the next season, it must be picked up by manpower first, and it will be hugged to the field or ridge with a rake, and then burned later, which seriously damages the environment. [0005] (3) Contents of the invention [0006] In order to make up for the defects of the prior art, the present invention provides a straw crushing biaxial reverse stubble removal and returning machine which integrates crushing, stubble removal, burying and leveling. [0007] The present invention is achieved through the following technical solutions: [0008]...
