Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, specifically to an explosion-proof hook shot blasting machine. Background Technology

[0002] A shot blasting machine is a machine that uses a high-speed rotating shot blaster to project shot particles onto the surface of a workpiece. Through impact and cutting, it removes dirt, oxide layers, rust, and other impurities from the workpiece surface, thereby achieving the purpose of cleaning, strengthening, or pre-treating the workpiece surface. The working principle of a shot blasting machine mainly relies on a motor driving the shot blasting wheel to rotate at high speed, generating centrifugal force and wind force, which accelerates the shot particles and projects them onto the workpiece.

[0003] Existing Chinese patent CN119501829A, published on February 25, 2025, discloses an explosion-proof hook-type shot blasting machine, relating to the field of shot blasting machine technology. It includes a shot blasting chamber with an opening at the top. The outer surface of the top of the shot blasting chamber is provided with cover plates on both sides of the opening. The two cover plates rotate to open and close, and in the closed state, the side walls of the two cover plates abut against each other. A first guide plate is connected to one end of the cover plate outside the shot blasting chamber, and a second guide plate is provided at the center of the top of the cover plate. A guide ring is provided on the lifting device, and an accommodating opening is provided between the two second guide plates for the lifting device to pass through.

[0004] However, the hook of the above-mentioned device lacks a corresponding hook positioning structure when it is lifted and moved, so it cannot be effectively positioned during transportation and overall displacement, which causes instability when placed.

[0005] Therefore, we propose a new type of explosion-proof hook shot blasting machine to solve the above-mentioned technical problems. Utility Model Content
