Description

Straw crushing device Technical Field The utility model relates to the technical field of straw crushing, in particular to a straw crushing device. Background Straw is used as waste in agricultural production, traditional treatment methods mainly depend on combustion, accumulation or simple composting, the methods not only waste resources, but also can pollute the environment, along with the enhancement of environmental awareness and the progress of science and technology, the crushing and recycling of the straw gradually become a feasible solution, the existing straw crushing equipment realizes the crushing of the straw to a certain extent, but when the feeding is actually carried out, the structure for fixing the straw is lacking, so that the straw is easy to shift and slide on a conveying belt, the feeding is uneven, the manual auxiliary arrangement is needed, and the operation efficiency is influenced. Disclosure of Invention The utility model aims to provide a straw crushing device for solving the problems in the background technology. In order to achieve the above purpose, the present utility model provides the following technical solutions: The straw crushing device comprises a conveying belt and a crushing box, wherein the crushing box is arranged on one side of the conveying belt, supporting legs are fixedly arranged on the lower sides of supports on two sides of the conveying belt, and straw fixing structures are arranged on the upper sides of the supports on two sides of the conveying belt; The straw fixed knot constructs including the fixed band, the both ends of fixed band all rotate there is the backing roll, the mount is installed through the pivot to the both sides of backing roll, and one side of mount is installed on the support of conveyer belt both sides through the montant, hold-down structure is installed to the downside of mount, the tight structure that rises is installed to the upside of mount.
