Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to a shot blasting screening and recovery device of a shot blasting machine. 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. The shot blasting machine can simultaneously remove sand, core and clean castings. In some areas, it is also verbally called a sandblasting machine or a sandblasting machine. Compared with other surface treatment technologies, it is faster and more effective. The shot blasting machine needs to screen and recycle the shot after use. Since different steps have systematic use requirements for projectiles of different diameters, a screening device is required to classify and recycle the projectiles.

[0003] When the shot blasting machine is finished, workers need to screen the shot blasting machine produced and clean up the waste on the shot blasting machine. This not only increases the labor intensity of the workers, but also reduces the screening efficiency.

[0004] To this end, we propose a shot blasting screening and recovery device for a shot blasting machine. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The shot blasting screening and recovery device of the shot blasting machine is provided with a first screen plate and a second screen plate. The driving motor drives the main shaft to rotate through the first synchronous wheel, the second synchronous wheel and the synchronous belt, thereby rotating the eccentric wheel, so that the supporting roller in rolling contact with the eccentric wheel moves up and down while rotating, so that the second screen plate vibrates, and at the same time, the first screen plate is driven to vibrate synchronously through the connecting roller and the supporting frame, so as to screen the mixed waste and shot blasting, reduce the labor intensity of workers, and improve the screening efficiency.

[0015] 2. The shot blasting screening and recovery device of the shot blasting machine is equipped with a collection box. The waste is screened by the first sieve plate and the second sieve plate and finally falls into the collection box. When the collection box is full, the worker pulls the collection box out of the screening box through the buckle. This not only prevents the waste generated when screening the shot material from being scattered all over the place, but also makes it convenient for the workers to deal with the waste.
