Description

Technical Field

[0001] The utility model relates to the technical field of straw crushing, in particular to an agricultural straw crushing machine. Background Technique

[0002] A crusher is a machine that crushes large-sized solid raw materials to the required size. In agricultural work, during the annual harvest season, since the utilization value of straw is not very significant, it is basically discarded or burned arbitrarily. This unreasonable treatment method not only causes waste of straw resources but also leads to serious environmental pollution problems. The use of crushers brings great convenience to people. For the crushing of straw, it needs to be thorough to avoid excessive pollution to the subsequent environment, and the crushed straw can also be used as fertilizer.

[0003] When the existing crushers are in use, manual feeding into the crushing device is required. When manually feeding, the straw needs to be pushed into the interior of the crusher, so it needs to come into contact with the crusher. In this way, there is a risk of the arm being clamped. For this reason, we propose an agricultural straw crushing machine. Content of the Utility Model
