Elastic mesh type straw compression pair roller

Abstract

The invention provides an elastic mesh type straw compression pair roller and belongs to the technical field of straw compression machines. The pair roller comprises a first compression roller assembly and a second compression roller assembly which are identical in structure and opposite in direction. Each compression roller assembly is composed of a left end cover assembly, a compression roller shaft assembly, a roller cylinder assembly, an elastic piece assembly, a rubber strip assembly and a right end cover assembly. The connection modes of the parts of the two compression roller assembliesare the same, but the elastic pieces are differently arranged. The elastic piece of the first compression roller is arranged in a left-handed mode, the elastic piece of the second compression rolleris arranged in a right-handed mode, and the elastic pieces are spirally meshed and installed to achieve elastic mesh type compression of straw. By means of the pair roller, forced pushing and feedingfor straw compression can be realized; meanwhile, the straw with different shape characteristics is subjected to elastic compression, the problems that in the straw compression process, the straw slides, is difficult to feed into the machine, is subjected to missing compression or is not compacted are solved, continuous high-strength compression can be realized, and the straw compression effect and efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of straw compression machinery, in particular to an elastic meshing straw compression pair roller used for straw pair roller compression. Background technique [0002] Crop straw is an important biomass resource. The world's annual output exceeds 2 billion tons, and my country's annual output exceeds 900 million tons. Straw is rich in organic matter and various nutrients such as nitrogen, phosphorus, potassium, and calcium, and can be used as fuel, feed, and fertilizer. , base materials and industrial raw materials, etc., have high use value. However, due to loose straw, low density and scattered distribution, the utilization rate of straw is low. Compression is a necessary process for the resource utilization of straw, which can increase the density of straw and facilitate the transportation and storage of straw, thereby reducing the cost of resource utilization of straw and improving the utilization rate. ...
