Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, and in particular to a material feeding and conveying structure for shot blasting machines. Background Technology

[0002] Shot blasting is a common surface treatment equipment. It uses a shot blaster to propel shot (such as steel shot, sand, etc.) at high speed onto the surface of a workpiece. The impact of the shot removes impurities such as oxide scale, rust, and dirt from the workpiece surface. At the same time, it can also give the workpiece surface a certain roughness, improve the adhesion of subsequent painting, coating and other processes, and can also be used to strengthen the workpiece surface and improve the mechanical properties such as fatigue strength.

[0003] The feeding and conveying structure of a shot blasting machine is mainly used to feed the workpieces or materials to be treated into the shot blasting chamber for surface treatment. Its design aims to ensure that the workpieces can enter the shot blasting area evenly and stably, and be effectively transported throughout the shot blasting process. Shot blasting machines have various feeding and conveying structures, including belt-type, chain-type, and spiral-type feeding and conveying structures.

[0004] Hook-type shot blasting machines are a common type of shot blasting cleaning equipment. Their transport structure includes a hook, a lifting mechanism, and a rotating mechanism. The hook is used to suspend workpieces and generally has sufficient load-bearing capacity to accommodate workpieces of different weights and sizes. During operation, the hook needs to enter the shot blasting chamber along with the machine; prolonged impact can easily damage it.
