Description

Technical Field

[0001] The utility model relates to the technical field of sand and stone crushers, in particular to a dustproof sand and stone crusher. Background Art

[0002] Sand and gravel are often used as high-quality building materials and concrete raw materials due to their good hardness and stable chemical properties. They are widely used in housing, roads, highways, railways, engineering and other fields. When sand and gravel are used as building aggregates, they need to be crushed. The specifications of the sand obtained after crushing vary according to the fields in which they are used. Crushing and processing sand and gravel with a crusher is currently a common method of sand and gravel processing.

[0003] In the prior art, a patent document with publication number CN214717395U proposes a sand and gravel separation crusher, including a dustproof mechanism, a crusher and a collecting mechanism. The dustproof mechanism includes a dustproof cover connected to the feed port of the crusher, a winding roller and a rubber sheet fixedly connected to the winding roller at one end. A feed port is opened on one side of the dustproof cover, and the dustproof cover covers the feed end of the crusher. The winding roller is rotatably connected to the dustproof cover and is arranged above the feed port, and the rubber sheet covers the feed port. The rubber sheet of the present application covers the feed port, thereby reducing the possibility of dust generated when crushing sand and gravel raw materials causing pollution to the environment.

[0004] In order to solve the problem that a large amount of dust is generated in the process of crushing sand and stone raw materials by the crusher, the dust is easily spread from the top of the crusher to the outside of the crusher, causing pollution to the surrounding environment. The existing technology uses rubber sheets to block the dust drifting to the feed port, thereby reducing the dust generated in the crusher from spreading to the outside of the crusher. However, there is a situation where the device is unable to block fine dust when blocking the dust, which leads to a problem of reducing the practicability of the crusher. Utility Model Content
