Description

Technical Field

[0001] The utility model relates to the technical field of crushing devices, in particular to a straw crusher. Background Art

[0002] As a major agricultural country, my country produces hundreds of millions of tons of crop straw every year. Except for a small part of these crop straws that are used, a large amount of them are abandoned, which not only wastes resources but also easily pollutes the environment. For this reason, people have thought of using straw to make livestock feed. Straw crushers can be used to crush corn stalks, straw, bean stalks and other crop waste stalks. The crushed crop debris can be used to make raw materials for various production industries such as organic fertilizer, fuel, particle board, paper, etc.

[0003] Among them, the "a kind of straw crusher" disclosed by the application number "CN219205310U" has solved the various drawbacks that the straw cannot be placed in an orderly manner, resulting in the straw being easy to collapse due to lack of support, causing the straw to fall around the crusher, being very scattered, and resulting in a dirty and messy working environment. After further searching, it was found that the "a kind of straw crusher" disclosed by the application number "CN215122290U" has effectively solved the technical drawbacks such as the straw after the straw crusher is not uniform, and the larger straw and qualified straw cannot be separated after crushing through a specific technical structure setting. However, in actual use, a straw crusher with a similar structure still has many defects, such as: most of the mainstream straw crushers on the market currently adopt a fixed blade design, but their crushing effect is not ideal. The fixed blade is difficult to adapt to the morphological changes of different straws, resulting in low crushing efficiency, high energy consumption, and easy to cause clogging. Therefore, it is necessary to improve the existing technical solutions to improve the adaptability and crushing effect of the straw crusher. Utility Model Content
