Roller cutter-type multi-position adjusting straw crusher

Abstract

The invention discloses a roller cutter-type multi-position adjusting straw crusher. The roller cutter-type multi-position adjusting straw crusher comprises a case with an opening in the rear end, wherein a material receiving plate is transversely arranged in an inner cavity of the case; first electric telescopic rods are vertically arranged on the upper surface of the material receiving plate; and the top ends of the first electric telescopic rods are fixedly connected with the top of an inner wall of the case. The invention relates to the technical field of crushers. According to the rollercutter-type multi-position adjusting straw crusher, the material receiving plate capable of moving up and down is arranged, a mounting frame capable of moving up and down is arranged below the material receiving plate, crushing shafts are arranged in the mounting frame, the heights at which the crushing shafts extend above the material receiving plate can be adjusted, and multi-position adjustingcan be carried out, so that the contact depths and crushing lengths of cutter devices and straws can be adjusted through coordinating action of the crushing shafts and the material receiving plate; and the roller cutter-type multi-position adjusting straw crusher can crush different kinds of straws, simultaneously can control the crushing lengths of the straws, can meet different processing requirements and has wider applicability.

Description

Technical field [0001] The invention relates to the technical field of crushers, in particular to a roller cutter type multi-position adjustable straw crusher. Background technique [0002] Biomass power generation is a kind of renewable energy power generation that uses the biomass energy of biomass. It includes direct combustion power generation of agricultural and forestry waste, power generation of agricultural and forestry waste gasification, waste incineration power generation, and landfill gas power generation. , Biogas power generation. [0003] Biomass power generation mainly includes the incineration of crop stalks for power generation. Due to the small density, large volume, and inconvenience of transportation and utilization, the straws must be pre-processed if they are to be fully burned. The main treatment method is crushing. [0004] When straw is burned for power generation, a crusher needs to be used for pre-crushing. In some existing straw crushers, the knife shaft...
