In the utility model, the dust generated during the crushing of sand and gravel is sprayed by the anti-dust mechanism, so that the dust is absorbed by water when it overflows the feed hopper, effectively preventing the dust from overflowing.

[0004] In order to solve the problem of preventing dust from being raised during the crushing of sand and gravel, the prior art is to set a baffle at the feed port to prevent dust from floating into the outside world, and then use the water inlet hole in conjunction with a water pump to spray the dust floating in the outside world. However, the water discharged from the water inlet hole is in the form of a water column, and the contact range with the dust is not large enough and it wastes water resources. Moreover, the water flowing out of the water inlet hole is easy to flow into the crusher body in large quantities, affecting the crushing operation of the crusher on the stone. Utility Model Content
