Technical Field

The invention relates to the technical field of material crushing, in particular to a dust-proof material crusher.

Background

The solid waste is a solid which is lost in its original utilization value or discarded or abandoned without losing its utilization value during production, living and other activities, and is generally crushed for more convenient transportation and storage, so that it is also convenient to effectively recover a certain component in the solid waste, but a great amount of dust is easily generated during the crushing of the solid waste to float in the air, thereby affecting the surrounding environment.

Patent publication number CN113477318A discloses a solid waste prevents raise dust reducing mechanism and application method thereof, including smashing the box, prevent raise dust mechanism outward, moving mechanism and interior raise dust mechanism, the top of smashing the box is fixed with the roof, is provided with the feed inlet on the roof, and the both sides of feed inlet all are provided with prevent raise dust mechanism outward, prevent raise dust mechanism outward and fix on moving mechanism, moving mechanism fixes on the roof, and the inside of smashing the box is separated into storage area, equipment area and crushing area through the division board.
