A collection frame is fixedly installed on the lower surface of the device main body. A filter frame is fixedly installed on the lower surface of the collection frame. A first filter screen is movably installed inside the filter frame. A filter cylinder is fixedly installed on one side of the device main body. A motor is fixedly installed on the lower surface of the filter cylinder. This steel track continuous passing type shot blasting cleaning machine can automatically clean the residual shot and impurities above the steel plate and steel track after shot blasting. And after the shot is used, the dust and impurities on the surface of the shot can be preliminarily cleaned while the shot is reloaded, avoiding the dust and impurities on the surface of the shot from entering the shot blasting bin again.

[0004] Based on the above search and combined with the prior art, it is found that when the prior art shot blasting cleaning machines similar to the above are cleaning, there are cleaning dead corners on the bottom surface of the workpieces, resulting in incomplete cleaning, and the workpieces need to be turned over for secondary cleaning, reducing the cleaning efficiency. Therefore, a continuous track shot blasting cleaning machine is proposed to improve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0025] Embodiment: Refer to Figures 1-4 A continuous track shot blasting cleaning machine shown, including a frame 1, a cleaning chamber 2 installed at the top of the frame 1, a shot blasting machine 3 installed at the top of the cleaning chamber 2, and a steel mesh track 4 horizontally installed inside the frame 1 and passing through the cleaning chamber 2.

[0026] Among them, the shot blasting machine 3 and the steel mesh track 4 can respectively adopt conventional shot blasting devices and steel mesh tracks in the prior art. The shot blasting machine 3 extends into the cleaning chamber 2, and the shot blasting sand is put and the shot blasting treatment is realized by using the shot blasting machine 3.

[0027] Among them, protective soft curtains 5 are installed at both ends of the cleaning chamber 2 along the conveying direction of the workpiece, which can effectively prevent the floating dust generated during the cleaning process from overflowing.

[0028] A turning device is installed at the side end of the frame 1 in the conveying direction of the steel mesh track 4. The turning device includes a protective housing 8, a driving mechanism and a clamping mechanism.

[0029] Specifically, the protective housing 8 is installed at the side end of the frame 1, the clamping mechanism is rotatably installed inside the protective housing 8 to clamp the workpiece, the driving mechanism is installed at the side end of the protective housing 8, and the output end of the driving mechanism is connected to the clamping mechanism to drive the clamping mechanism to drive the workpiece to rotate along the axis of the workpiece.

[0030] Regarding the clamping mechanism, more specifically, as Figure 2 and Figure 3 shown, the clamping mechanism includes a rotating ring 9 and a plurality of clamping driving devices 10. The rotating ring 9 is rotatably installed inside the protective housing 8, the driving mechanism is connected to the rotating ring 9, and the plurality of clamping driving devices 10 are equidistantly installed on the circumferential side of the rotating ring 9, and the output end of the clamping driving device 10 extends towards the center of the rotating ring 9 to clamp the workpiece.

[0031] Among them, a roller 11 is rotatably installed at the output end of the clamping driving device 10. The rotation axis of the roller 11 is perpendicular to the conveying direction of the workpiece. While the workpiece is clamped by the roller 11, the workpiece can be stably and continuously conveyed under the transmission of the steel mesh track 4. Among them, the clamping driving device 10 can adopt a conventional electric push rod in the prior art.

[0032] Regarding the driving mechanism, more specifically, as Figure 2 and Figure 3 shown, the driving mechanism includes a driving motor 12, a driving gear 13 and a driven external tooth ring 14. The driving motor 12 is fixed on the outside of the protective housing 8, the output end of the driving motor 12 extends into the inside of the protective housing 8 and is coaxially fixed with the driving gear 13, and the driven external tooth ring 14 is coaxially fixed and sleeved on the outside of the rotating ring 9 and meshes with the driving gear 13.

[0033] In the state where the workpiece is clamped by the roller 11, the driving motor 12 drives the rotating ring 9 to rotate through the driving gear 13 and the driven external tooth ring 14, so that the workpiece rotates along its own axis, so that the surface of the workpiece is cleaned more comprehensively and thoroughly, without secondary cleaning, and the cleaning efficiency is improved.

[0034] It should be further explained that the arrangement of multiple clamping drive devices 10 in conjunction with the roller 11 can meet the clamping requirements of workpieces with different cross-sectional shapes and can be well applied to continuous crawler shot blasting operations.

[0035] In addition, it needs to be further explained that the clamping effect between the roller 11 and the workpiece mentioned in this scheme is not a conventional tight clamping effect, but the roller 11 is used to limit the workpiece. On the one hand, multiple rollers 11 are used to limit the workpiece so that the workpiece rotates with the rotating ring 9. On the other hand, the roller 11 can rotate when the workpiece is transported by the steel mesh crawler 4, and rolling friction occurs between the roller 11 and the workpiece, thereby reducing the friction during the workpiece transportation process.

[0036] In order to better adapt to the clamping requirements of workpieces with different cross-sectional shapes, a lifting drive device 7 is vertically installed on the side end of the frame 1, and a lifting seat 6 is installed on the top output end of the lifting drive device 7. The upper end of the lifting seat 6 is connected to the protective shell cover 8. The lifting drive device 7 can adopt a conventional electric push rod in the existing technology.

[0037] In order to improve the stability during the workpiece conveying and cleaning process, two flipping devices are provided. Both flipping devices are located on the conveying path of the workpiece and are located on both sides of the cleaning chamber 2. The two flipping devices can balance the force on the workpiece and make the rotation smoother.

[0038] The working principle of the utility model is as follows: according to the actual cross-sectional shape of the workpiece, the height of the lifting seat 6 is adjusted by the lifting drive device 7, and the workpiece is clamped by the clamping drive device 10 in cooperation with the roller 11. The driving motor 12 rotates the rotating ring 9 through the driving gear 13 and the driven outer gear ring 14, so that the workpiece rotates along its own axis, and the shot blasting machine 3 is used to realize the delivery and shot blasting of shot sand, so that the surface cleaning of the workpiece while being transported while rotating is more comprehensive and thorough, without the need for secondary cleaning, thereby improving the cleaning efficiency.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
