Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to a crawler-type shot blasting machine for fine processing of metal parts. Background Art

[0002] The crawler shot blasting machine is mainly composed of a cleaning chamber, a shot blasting wheel assembly, an elevator, a separator, an electrical system and other parts. During shot blasting, a specified number of workpieces are added to the cleaning chamber. After the machine is started, the projectiles thrown out by the shot blasting wheel at high speed form a stream of shot beams, which evenly hit the surface of the workpiece, thereby achieving the purpose of cleaning and strengthening.

[0003] A search of Chinese patent publication number CN213765456U discloses a crawler-type shot blasting machine in the field of surface treatment technology. This machine solves the technical problem of scattered steel shot near existing crawler-type shot blasting machines, which is difficult to handle. The machine comprises a base and a machine body mounted on the base. The base has an annular collection trough that surrounds the machine body and an annular mounting cover with several slots. This makes it easy to handle scattered steel shot near the crawler-type shot blasting machine.

[0004] Based on the above search and combined with the existing technology, we found that:

[0005] In the existing device, some of the projectiles will be broken during use, and the remaining projectile shells and clean steel shots will be scattered together and concentrated in the collection tank during discharge, which is not convenient for recycling. In addition, the staff must personally clean, collect and screen them for reuse, which adds steps to the staff's work. Utility Model Content
