Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, and in particular to a detachable sound-absorbing and noise-reducing cover structure. Background Technology

[0002] Hook-type shot blasting machines are key equipment widely used in metal surface treatment. They achieve multiple process objectives such as cleaning, strengthening, and deburring by impacting the surface of workpieces with a high-speed shot stream.

[0003] Most existing overhead rail shot blasting machines have a chute at the top of the shot blasting chamber located at the hook system. However, most of these chutes do not have a cover assembly. When the shot blasting machine is working, the shot moves at high speed in the chute, collides with each other, and impacts the chute wall, generating strong mechanical noise. This noise will spread directly to the surrounding environment without any obstruction. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A detachable sound-absorbing and noise-reducing cover structure includes a shot blasting machine body 1. The shot blasting machine body 1 includes a shot blasting cleaning chamber and a hook unit. A slide groove is provided at the top of the shot blasting cleaning chamber at the hook unit. Multiple limiting components 23 are symmetrically provided at equal distances on both sides of the slide groove at the top of the shot blasting cleaning chamber. A cover component 2 is provided at the slide groove at the top of the shot blasting cleaning chamber. The cover component 2 and the shot blasting cleaning chamber are connected by multiple limiting components 23.

[0023] It is worth noting that the specific structure, connection method and working principle of the shot blasting machine body 1 are all existing technologies that are currently publicly available on the market, and are not the main technical problems to be solved in this utility model. Therefore, this utility model will not elaborate on them.

[0024] The cover assembly 2 includes a main cover 21, an auxiliary sliding groove is provided at the top center of the main cover 21, and an auxiliary cover assembly 22 is inserted into one side of the main cover 21. The auxiliary cover assembly 22 and the main cover 21 are magnetically connected.

[0025] Meanwhile, extension plates 211 are symmetrically installed at both ends of the main cover 21. An inlet / outlet groove is provided in the extension plate 211 at the limit component 23, and a through hole is provided at one end of the main cover 21. T-shaped guide blocks 213 are symmetrically installed on both sides of the inlet / outlet groove.

[0026] Meanwhile, the limiting component 23 includes a T-shaped fixing block 231, which includes a fixing part and a limiting part. The limiting part is fixedly installed on one side of the fixing part, and one end of the fixing part is connected to the shot blasting chamber. The height of the fixing part is twice the thickness of the extension plate 211.

[0027] Furthermore, limiting protrusions 232 are symmetrically installed at both ends of the outer wall of the fixed part on the side near the shot blasting chamber, and the height of the limiting protrusions 232 is consistent with the thickness of the extension plate 211.

[0028] Furthermore, a limiting member 233 is fitted around the T-shaped fixing block 231, and the thickness of the limiting member 233 is the same as the thickness of the extension plate 211. The limiting member 233 includes a mounting ring, on both sides of which extension blocks are symmetrically mounted. A locking groove is formed through the inner side of the mounting ring at the corresponding limiting protrusion 232, and the locking groove is at the same horizontal line as the extension block. At the same time, an extension rod is installed on the top of each extension block, and a handle 234 is connected to one side of the extension rod. The length of the extension rod is the same as the length of the fixing part.

[0029] Furthermore, the auxiliary cover assembly 22 includes a fixing plate 221. Limiting grooves are formed on both sides of the fixing plate 221 at the T-shaped guide blocks 213. The bottom of the fixing plate 221 is located at the main sound-absorbing cotton body 212. A magnetic limiting plate 222 is installed on one side of the fixing plate 221, and a groove is formed on one side of the main cover 21 at the magnetic limiting plate 222. The groove is made of a material that magnetically attracts the magnetic limiting plate 222. The length of the fixing plate 221 is less than the length of the auxiliary grooves. The auxiliary grooves ensure that the hook unit can be used normally after the auxiliary cover assembly 22 is removed.

[0030] In this embodiment, by rotating the limiting member 233 to align its locking groove with its limiting protrusion 232 and inserting it, the main cover 21 is then inserted, and the limiting member 233 is moved by holding the handle and positioned above the extension plate 211. Then it is rotated until the limiting member 233 is rotated to an intersecting state with the inlet and outlet groove, thus completing the installation of the main cover 21.

[0031] When the hook unit is needed, the auxiliary cover assembly 22 is disassembled. After the hook unit is located in the shot blasting cleaning box, the auxiliary cover assembly 22 is inserted into the main cover 21 and magnetically attached to complete the installation of the overall cover assembly 2.

In conjunction with the installation of the main sound-absorbing cotton block 212 and the auxiliary sound-absorbing cotton block 223, the noise reduction effect is further enhanced.

[0033] In this utility model, a detachable cover assembly 2 is provided outside the slide groove located at the hook unit of the shot blasting machine body 1 to enclose the slide groove area, thereby limiting the propagation path of noise. In conjunction with the setting of the main sound-absorbing cotton block 212 and the auxiliary sound-absorbing cotton block 223, the noise reduction effect is further enhanced.
