Rice straw shattering and returning machine

Abstract

The invention relates to a returning machine, in particular to a rice straw shattering and returning machine. A suspension frame is installed in the center of the front end of a machine frame. A gearbox is installed at the front end of the upper surface of the machine frame. An output shaft is arranged at the left end of the gearbox. The output shaft is in transmission connection with one end of a flail knife roller through a first side transmission mechanism, the two ends of the flail knife roller are rotationally connected with the machine frame, the other end of the flail knife roller is in transmission connection with one end of a fixed knife roller through a second side transmission mechanism, the two ends of the fixed knife roller are rotationally connected with the machine frame, the outer circumferential face of the flail knife roller is provided with a plurality of flail knife blade sets, the outer circumferential face of the fixed knife roller is provided with a plurality of fixed knife blade sets, the rear ends of the left and right sides of the machine frame are each detachably and fixedly connected with a land wheel assembly with the adjustable land wheel height, an upper cover plate is detachably fixed to the front portion of the upper end of the machine frame, and a dispersion plate is detachably fixed to the rear portion of the upper end of the machine frame. By means of two-shaft transmission, the rotating speed can be increased, straw can be shattered to be in the shape of filaments or cotton, the shattered straw is sunk in soil, the dispersion effect is good, the dispersion range is wide, and dispersion is uniform.

Description

technical field [0001] The invention relates to a field returning machine, in particular to a rice straw crushing and returning machine. Background technique [0002] Scientific experiments have shown that the straw returning of rice, wheat, corn and other crops can not only increase the organic matter content of the soil, increase fertilizer efficiency, improve soil structure, but also reduce labor intensity and effectively avoid environmental pollution caused by straw burning. Most of the currently used rice straw crushing and returning machines are driven by a single shaft, and the rotation speed is low. In addition, the rice straw crushing and returning machine in the prior art cannot crush the straw, but can only break the straw into segments, and the segmented straws can only float on the water surface and cannot sink into the soil, and now A technical spreader spreads poorly. Contents of the invention [0003] The purpose of the present invention is to provide a r...
