Cutter shaft structure and single shaft crusher

Abstract

The invention discloses a cutter shaft structure. The cutter shaft structure comprises a cutter shaft main body 101, wherein the cutter shaft main body 101 is provided with a cylindrical surface, a plurality of cutter granules 202 arranged in the axial direction of the cutter shaft main body 101 are arranged on the cylindrical surface, every two adjacent cutter granules 202 are tightly attached to each other, and therefore no interval exists between teach two adjacent cutter granules 202, and furthermore compared with a sparse arrangement distribution mode, the larger quantity of the cutter granules 202 are arranged on the cutter shaft main body by adopting the attaching arrangement mode so as to improve cutting efficiency. Additionally, the invention further provides a single shaft crusher. The single shaft crusher comprises a cutter shaft and a stationary cutter 102 which cooperates with the cutter shaft for cutting, wherein the cutter shaft is set to be of the above cutter shaft structure. By rotating a crushing blade towards the stationary cutter 102 and then performing cutting work under cooperation of the crushing blade and the stationary cutter 102, the single shaft crusher greatly improves cutting speed and cutting efficiency, and can meet high yield and low cost requirements of solid waste well by combining with beneficial effects of the above cutter shaft structure.

Description

technical field [0001] The invention belongs to the technical field of crushers, and in particular relates to a cutter shaft structure and a single-shaft crusher adopting the cutter shaft structure. Background technique [0002] With the rapid development of our country's society, economy and industry over the years, the amount of solid waste generated has also become larger and larger. In the process of processing a wide variety of solid waste according to the principle of "harmless, resourceful, and reduced", the single-shaft crusher has uniform crushing size, can control the discharge size through the screen, and has short maintenance time. And other advantages, more and more widely used in solid waste shredding. However, the existing single-shaft crushers have the problems of low cutting and discharging efficiency, fast tool wear and high operating costs. The protruding height of the grains is low, which further leads to insufficient cutting capacity, resulting in low ...

AI Technical Summary

Problems solved by technology

However, the existing single-shaft crushers have the problems of low cutting and discharging efficiency, fast tool wear and high operating costs. The protruding height of the grains is low, which further leads to insufficient cutting capacity, resulting in low feeding efficiency; moreover, there is no effective measure to discharge the crushed materials in time, resulting in low discharging efficiency

If the material cannot be discharged in time, it will increase the wear of the knife grains, resulting in low output and high wear of the knife grains. For customers, it means that the cost of the knife per ton of material is high, and it is difficult to match the high output and low cost of solid waste.
