Description

Technical Field

[0001] The invention discloses a belt-driven high-efficiency shot blasting machine, belonging to the technical field of shot blasting equipment. Background Art

[0002] Shot blasting machine is a device that sprays steel shot evenly and hits the surface of the workpiece to remove rust from the workpiece surface. Shot blasting machine is divided into two types: belt drive and motor direct connection, both of which have their own advantages. Steel shot needs to be fed into the shot blasting machine through a steel shot conveying pipe. Since the pipes for conveying steel shot have various angles at the site of use, the angle of the steel shot conveying pipe needs to be adjusted. The steel shot conveying pipe is usually set on the shot blasting machine by rotating the pressure plate to adapt to pipes of various angles. However, the vibration of the belt-driven shot blasting machine is greater than that of the direct-connected shot blasting machine. During the operation of the shot blasting machine, the vibration can easily cause the steel shot conveying pipe to deflect. It is difficult to ensure that the angle of the steel shot conveying pipe is fixed and stable by relying solely on the pressure plate. Once deflection occurs, it will affect the normal operation of the shot blasting machine. Utility Model Content
