Stubble crushing and throwing machine

Abstract

The invention discloses a stubble crushing and throwing machine, relates to an agricultural machine and aims to provide a stubble crushing and throwing machine which is high in straw crushing and refining degree and beneficial to planting. The stubble crushing and throwing machine comprises a rack, a shell, first-stage crushing hammers and second-stage crushing hammers, wherein the first-stage crushing hammers and the second-stage crushing hammers are respectively fixed on the rack in the axial direction; the first-stage crushing hammers and the second-stage crushing hammers are arranged in parallel front and back; the shell is fixedly arranged on the rack; a top plate of the shell is positioned above the first-stage crushing hammers and the second-stage crushing hammers; the first-stage crushing hammers are semi-wrapped by a left plate of the shell; the second-stage crushing hammers are semi-wrapped by a right plate of the shell.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a device for processing straw. Background technique [0002] Straw pulverizer refers to agricultural machinery used for crushing crops such as straw, which greatly improves the efficiency of straw processing. For example, Chinese patent CN2394420Y discloses a straw pulverizer, which includes a frame and a cutting assembly. Driven by the device, the cutting assembly crushes the straw. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] Its structure is a one-time fast crushing machine, and its principle is to rely on the principle of agricultural machinery transmission to drive the movable hammer to quickly crush the straw and crop stubble in a centrifugal form, so as to achieve the principle of not affecting the next stubble planting. However, so far, no one has Advanced equipment can m...

Problems solved by technology

[0004] Its structure is a one-time fast crushing machine. Its principle is to rely on the principle of agricultural machinery transmission to drive the movable hammer to quickly crush the straw and crop stubble in a centrifugal form, so as to achieve the principle of not affecting the next stubble planting. However, so far, no one has Advanced equipment can meet the crushing requirements, and it will still affect the planting of the next stubble without incineration or manual cleaning;
