Problems solved by technology

[0003] Straw grinder is a kind of organic fertilizer production equipment. During the production process, the operator needs to manually push the straw, which causes the operator's palm to be too close to the grinder, which reduces the safety of the straw grinder. Not only that, the existing When the advanced straw grinder is in use, the straw usually contains small stones. If the small stones enter the crushing device, it will cause damage to the crushing device and reduce the practicability of the straw grinder.
