[0002] A crusher is a mechanical device used to break materials into smaller particles. They are often used in recycling sites to process waste sand. Crusher usually compresses or squeezes the raw materials by applying force, or breaks the raw materials by impact, shearing, and collision. In the process of recycling waste sand, crushers are often used to crush the waste sand.

[0003] At present, when a crusher is used to crush waste molding sand, a lot of dust is easily generated inside the crusher. In the document with patent number CN220641793U, a dust-proof structure for a discharge port that is easy to replace is proposed, which relates to the technical field of dust-proofing for stone discharge. The dust-proof structure for a discharge port that is easy to replace includes a dust-proof shell, and fan blades are circumferentially arranged inside the dust-proof shell to adsorb dust during the stone feeding process. A driving mechanism is arranged on one side of the dust-proof shell; the fan blades are driven by a driving motor to rotate to generate suction, and dust is sucked onto the inner wall of the filter screen during the falling of the stone. During the rotation of the fan blades, the convex blocks on the top of the filter screen are moved to make the filter screen shake, so that the dust on the filter screen can be shaken off into the dust collecting trough below. A dust removal port is provided on the inner side of the dust collecting trough, which can be opened to discharge dust. The filter screen is fixed on the top of the dust collecting trough, and the dust collecting trough is connected to the dust-proof shell through threads, which is convenient for quick installation and replacement.
