Abstract

The invention relates to the field of crop harvesting, further relates to a crop processor (namely a machine for crushing or grinding straw), in particular to a reciprocating cutter type straw crushing device which comprises a base, a first rotary drum, a second rotary drum, a conical column and a crushing assembly, and the first rotary drum and the second rotary drum are rotationally installed on the base in opposite directions; the conical column is mounted in the first rotary drum and the second rotary drum; the crushing assembly comprises a plurality of crushing rings which are distributed at intervals from top to bottom along the peripheral wall of the conical column; every two adjacent crushing rings are connected through a pressure spring; second cutter bars extending in the radial direction of the first rotary drum are arranged on the inner walls of the first rotary drum and the second rotary drum; a spiral groove is formed in the outer circumference of the conical column, when straw is stacked between the first rotating cylinder and the conical column, the first rotating cylinder rotates and pushes the whole crushing ring to move upwards along the spiral groove, and when straw is stacked between the second rotating cylinder and the conical column, the second rotating cylinder rotates and pushes the whole crushing ring to move downwards along the spiral groove; and the utilization rate of the cutter bar is improved.

Description

technical field [0001] The invention relates to the field of crop harvesting, in particular to a reciprocating cutter type straw crushing device. Background technique [0002] Straw usually refers to the remaining part of wheat, rice and other crops after harvesting the seeds. Straw is a renewable biological resource with multiple uses and a kind of roughage. my country is a big agricultural country, crops can generate a large amount of straw every year, and comprehensive utilization can promote farmers' income increase, environmental protection and resource conservation. [0003] Straw can be crushed and compressed into solid biomass fuel, which can be used as feed to feed cattle and sheep after cutting and fermentation. straw machinery) to cut and pulverize the straw. When cutting straw, the existing straw cutting device mostly uses a cutter that rotates with the rotating shaft to cut the straw, but the size of the straw is different, and the distribution in the cutting ...
