[0002] Straw is the straw residue left after the crops are harvested, including corn straw, rice straw, wheat straw, etc. In agricultural production, straw usually needs to be crushed for better use. Traditional straw crushers usually use mechanical crushing, but there are some problems in actual use.

[0003] The feeding structure of a general straw crusher is relatively simple. Since the straw is piled up after harvesting, the straw at the feed port is messy and complicated, which is not conducive to smooth feeding and efficient crushing. At the same time, due to the shape and material characteristics of the straw, it is easy to cause the straw to pile up at the feed port, and manual hammering operation is required at the feed port, which not only increases the complexity of manual operation, but also increases production costs and safety hazards, seriously affecting the working efficiency and safety of the crusher.
