Description

Technical Field

[0001] The utility model relates to the technical field of top sealing, and more specifically, to a linkage type top sealing device of a hook shot blasting machine. Background Art

[0002] During operation, high-speed steel shot blasting machines clean or strengthen the surfaces of castings, forgings, and welded components. However, if the top notch is not tightly sealed, shot blasting can splash out, potentially causing damage to personnel and equipment. The hook shot blasting machine's linked top sealing device tightly seals the notch, effectively preventing shot blasting.

[0003] In existing public literature, patent publication number CN208100144U discloses a novel top sealing device for the cleaning chamber of a hook-type shot blasting machine. This technology maximizes the sealing of the hook slot by providing a fan-shaped cover plate and a movable sealing cover plate. The movable sealing cover plate is made of steel and has a wear-resistant rubber layer attached underneath. This improves the sealing performance while making the movable sealing cover plate more wear-resistant. When severe wear occurs, only the wear-resistant rubber layer needs to be replaced, which is low-cost. However, this technology still has the following problems when used:

[0004] During the linkage process of the hook shot blasting machine, it is necessary to implement a sealing operation on the top. However, it is difficult to perform a flexible sealing connection according to the linkage position during the top sealing process. Direct hard connection will cause greater wear, making the sealing device less durable. Utility Model Content
