Detailed Description of the Preferred Embodiments

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figures 1-4, an embodiment provided by the present utility model: a drum shot blasting cleaning machine, including a collection bottom box 1. A cavity is provided inside the collection bottom box 1. The right end of the outer cylinder 3 is fixedly connected with a connecting pipe 10. A blower 11 is fixedly connected to the inner wall of the connecting pipe 10. The right end of the connecting pipe 10 is fixedly connected with a filter box 12. A connecting plate 16 is provided on the inner wall of the top end of the filter box 12. A handle 17 is fixedly connected to the top end of the connecting plate 16. A screen 18 is fixedly connected to the bottom end of the connecting plate 16. The bottom end of the filter box 12 is fixedly connected with a second collection pipe 15. The bottom end of the second collection pipe 15 is fixedly connected to the top right side of the collection bottom box 1. The right end of the filter box 12 is fixedly connected with an air outlet 13. A dust-proof cover 14 is fixedly connected to the inner wall of the right end of the air outlet 13. Fixed blocks 19 are slidably connected to the front and rear ends of the filter box 12. The fixed blocks 19 are connected to the filter box 12 through springs 20. One end of the spring 20 is connected to the fixed block 19, and the other end of the spring 20 is connected to the inner wall of the filter box 12. The bottom ends of the paddles 21 are fixedly connected to the top ends of the fixed blocks 19;

[0025] Specifically, when the workpiece needs to be taken out, by starting the blower 11, the dust floating in the outer cylinder 3 is driven to enter the filter box 12 through the connecting pipe 10 and is blocked by the screen 18. The subsequent air can be discharged through the air outlet 13, and dust prevention can be achieved through the dust-proof cover 14. The dust blocked by the screen 18 can enter the collection bottom box 1 through the second collection pipe 15 for collection. And when the screen 18 needs to be replaced, by pulling the paddles 21 on both sides outwards, the fixed blocks 19 on both sides are driven to move outwards, thereby releasing the fixation of the fixed blocks 19 on the connecting plate 16. By pulling the handle 17, the screen 18 on the connecting plate 16 is driven to move outwards to disassemble the screen 18. When the screen 18 needs to be installed, by placing the connecting plate 16 in a suitable position, the elastic force of the spring 20 drives the fixed block 19 to move inwards, thereby fixing the connecting plate 16 and enabling the installation of the screen 18.

[0026] Support plates 2 are fixedly connected to the front and rear sides of the top end of the collection bottom box 1. Outer cylinders 3 are respectively fixedly connected to the top ends of the support plates 2. A driving motor 4 is fixedly connected to the front end of the outer cylinder 3. A cleaning drum 5 is fixedly connected to the driving end of the driving motor 4. A plurality of filter holes 6 are provided on the outer wall of the cleaning drum 5. A feed inlet 7 is fixedly connected to the rear end of the cleaning drum 5. The front end of the door cover 8 is rotatably connected to the rear end of the feed inlet 7. The bottom end of the outer cylinder 3 is fixedly connected with a first collection pipe 9. The outer wall of the feed inlet 7 is rotatably connected to the inner wall of the rear end of the outer cylinder 3. The bottom end of the first collection pipe 9 is fixedly connected to the top left side of the collection bottom box 1;

[0027] Specifically, by opening the door cover 8, shot and workpieces are put into the cleaning drum 5 through the feed inlet 7. Then, by starting the driving motor 4, the cleaning drum 5 is driven to rotate, thereby cleaning the dust and impurities on the surface of the workpiece. While the cleaning drum 5 is rotating, the dust and impurities can be discharged through the filter holes 6 and collected into the collection bottom box 1 through the first collection pipe 9 to prevent impurity accumulation and re - adhesion of impurities to the workpiece.

[0028] Working principle: First, by opening the door cover 8, shot and workpieces are put into the cleaning drum 5 through the feed inlet 7. Then, by starting the driving motor 4, the cleaning drum 5 is driven to rotate, thereby cleaning the dust and impurities on the surface of the workpiece. While the cleaning drum 5 is rotating, the dust and impurities can be discharged through the filter holes 6 and collected into the collection bottom box 1 through the first collection pipe 9 to prevent impurity accumulation and re - adhesion of impurities to the workpiece. When the workpiece needs to be taken out, by starting the blower 11, the dust floating in the outer cylinder 3 is driven to enter the filter box 12 through the connecting pipe 10 and blocked by the screen 18. The subsequent air can be discharged through the air outlet 13, and dust prevention can be achieved through the dust - proof cover 14. The dust blocked by the screen 18 can enter the collection bottom box 1 through the second collection pipe 15 for collection. And when the screen 18 needs to be replaced, by pulling the paddles 21 on both sides outwards, the fixed blocks 19 on both sides are driven to move outwards, thereby releasing the fixation of the fixed blocks 19 on the connecting plate 16. By pulling the handle 17, the screen 18 on the connecting plate 16 is driven to move outwards to disassemble the screen 18. When the screen 18 needs to be installed, by placing the connecting plate 16 in the appropriate position, the elastic force of the spring 20 drives the fixed blocks 19 to move inwards, thereby fixing the connecting plate 16 and enabling the installation of the screen 18.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
