Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to a shot-residue separation device for shot blasting machines. Background Art

[0002] Shot blasting machine refers to casting equipment that uses high-speed projectiles thrown by the shot blaster to clean or strengthen the surface of castings. Shot blasting machine can simultaneously remove sand, core and clean castings. In some areas, it is also called sandblasting machine or sandblasting machine. Existing shot blasting machines are usually equipped with shot slag separation devices, which can separate shot and slag, so that the shot can be recycled.

[0003] In Chinese utility model patents, for example, the utility model of CN220007406U discloses a shot-residue separation device for a shot blasting machine, which includes a shot blasting machine body, and a screening mechanism is used to separate shot materials of various sizes at one time, thereby saving the floor space of the workshop. A chip removal mechanism is used to separate shot materials from slag materials, and a rotating brush enhances the separation effect, so that the shot materials and slag materials are fully separated.

[0004] The above technology accumulates the shot on the screening part with the smallest sieve diameter, and pushes the push plate forward through the telescopic rod and the spring, so that the accumulated material gradually moves upward, and then the shot is separated through different screening parts. However, when too much shot is accumulated, the gaps in the accumulated shot will be filled with impurities, resulting in the push plate being unable to insert from the gap in the middle of the shot and contact the top surface of the sieve plate, thereby failing to push the shot from the bottom, and thus only the shot above can be taken away each time. Moreover, as more shot enters the feed port, the worse the screening effect is, which in turn affects the subsequent shot-residue separation operation. Utility Model Content
