Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art 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 lifting device for a shot blasting cleaning machine includes a device box 1. A movable door 2 is rotatably connected to the left side of the front end of the device box 1. Transmission shafts 9 are rotatably connected to the upper and lower inner walls of the rear end of the device box 1 and penetrate through the front side. A motor 19 is fixedly connected to the upper side of the rear end of the device box 1. The front end of the upper transmission shaft 9 penetrates through the device box 1 and is fixedly connected to the driving end of the motor 19. Opposite ends of the outer diameter of the transmission shaft 9 are meshed with a conveyor belt 14. A plurality of hoppers 10 are fixedly connected to the outer wall of the conveyor belt 14. When the motor 19 is started, the upper transmission shaft 9 rotates, and then under the driving action of the conveyor belt 14, the lower transmission shaft 9 rotates synchronously, thereby realizing the rotation of the conveyor belt 14 and driving the multiple hoppers 10 on the outer wall to rotate in sequence. A discharge port 6 is opened on the upper left side of the device box 1, and a feed port 11 is opened on the lower right side of the device box 1.

[0025] Specifically, a second material guiding frame 12 is fixedly connected to the bottom end of the inner wall of the feed inlet 11. When the hopper 10 passes through the second material guiding frame 12, abrasive grains are put into the feed inlet 11. Along the guiding of the second material guiding frame 12, they enter the hopper 10. Then, with the rotation of the conveyor belt 14, they are lifted upward. A first material guiding frame 8 is fixedly connected to the inner wall of the left end of the device box 1 near the lower side of the discharge port 6. A receiving box 15 is detachably connected to the inner wall of the bottom end of the device box 1. A chip removal box 3 is fixedly connected to the left end of the device box 1 near the lower side of the discharge port 6. A placement groove 4 is formed in the middle of the front end of the chip removal box 3. A metal mesh plate 17 is fixedly connected to the top of the inner wall of the chip removal box 3. The mesh holes of the metal mesh plate 17 are relatively large, allowing chips to fall. When the hopper 10 filled with abrasive grains passes through the first material guiding frame 8, as the hopper 10 tilts, the abrasive grains are thrown towards the discharge port 6. Along the guiding effect of the first material guiding frame 8, the abrasive grains will roll onto the top of the metal mesh plate 17. Side protection frames 7 are fixedly connected to the front and rear sides of the top end of the chip removal box 3. The side protection frames 7 prevent the abrasive grains from rolling out and falling to the outside. A suction fan 16 is fixedly connected to the inner wall of the bottom end of the chip removal box 3 and penetrates through the upper and lower sides. A collection box 5 is detachably connected to the inner wall of the placement groove 4. A dust filter screen 13 is fixedly connected to the inner wall of the bottom end of the collection box 5. The suction fan 16 is started to draw the top airflow into the chip removal box 3. The impurities or chips on the surface of the abrasive grains, under the action of the negative pressure airflow, fall into the chip removal box 3 along the gaps of the metal mesh plate 17 and finally fall into the collection box 5 and are blocked in the collection box 5 by the dust filter screen 13. Some of the remaining impurities and chips in the hopper 10 will fall into the receiving box 15 due to gravity. The abrasive grains after surface cleaning are discharged along the through holes of the side protection frames 7. Support plates 18 are fixedly connected to the inner walls of the left and right ends of the chip removal box 3 near the lower side of the placement groove 4. The top ends of the support plates 18 are respectively in contact with the left and right sides of the bottom end of the collection box 5. Then, the movable door 2 is opened and the receiving box 15 is taken out for cleaning. The collection box 5 can be directly pulled out of the chip removal box 3, and the impurities and chips collected on the top of the dust filter screen 13 can be cleaned up.

[0026] Working principle: First, start the motor 19 to rotate the upper transmission shaft 9. Then, under the driving action of the conveyor belt 14, the lower transmission shaft 9 rotates synchronously, thereby realizing the rotation of the conveyor belt 14 and driving the multiple hoppers 10 on the outer wall to rotate in sequence. When the hopper 10 passes by the second material guiding frame 12, the shot is put into the feeding port 11, and under the guiding of the second material guiding frame 12, it enters the hopper 10. Then, with the rotation of the conveyor belt 14, it is lifted upward. When the hopper 10 filled with shot passes by the first material guiding frame 8, as the hopper 10 tilts, the shot is put into the discharge port 6. Under the guiding action of the first material guiding frame 8, the shot rolls onto the top of the metal mesh plate 17. At the same time, start the exhaust fan 16 to suck the top air flow into the chip removal box 3. The impurities or debris on the surface of the shot, under the action of the negative pressure air flow, fall into the chip removal box 3 through the gaps of the metal mesh plate 17, and finally fall into the aggregate box 5 and are blocked in the aggregate box 5 by the dust filter net 13. Some of the remaining impurities and debris in the hopper 10 will fall into the receiving box 15 due to gravity. The shot after surface cleaning is discharged through the through hole of the side guard frame 7. Then, open the movable door 2 to take out the receiving box 15 and clean it. The aggregate box 5 can be directly pulled out from the chip removal box 3 to clean the impurities and debris collected on the top of the dust filter net 13.
