The sliding tube is slidably connected to the feeding pipe. The output end of the electric push rod is fixedly connected to one end of the sliding tube, which improves the ease of use of the device.

[0006] Preferably, the control terminals of the motor and the electric actuator are both electrically connected to an external power source via an external switch, which facilitates the operation of the device.

[0007] Preferably, the dust collection mechanism includes a dust collection tank, which is installed on one side of the main body. A negative pressure fan is also installed on one side of the main body, and the input end of the negative pressure fan is connected to the output end of the dust collection tank. A second feeder is installed at the bottom of the dust collection tank, and a waste cart is provided at the output end of the second feeder.

[0008] Preferably, the control terminals of the negative pressure suction fan and the second conveyor are both electrically connected to an external power source via an external switch, which facilitates the operation of the device.

[0009] Preferably, the recycling mechanism includes a collection box, which is installed at one end of the main body.

A third feeder is installed at the bottom of the collection box, and a fourth feeder is installed at the output end of the third feeder. A hoist is installed on one side of the main body, and the input end of the hoist is connected to the output end of the fourth feeder. The output end of the hoist is located at the top of the material box. An overflow pipe is connected to the upper middle part of the material box, and the bottom end of the overflow pipe is located at the top of the collection box, thereby reducing the user's workload and improving the utilization rate of the projectiles.

[0010] Preferably, the auxiliary mechanism includes a distribution duct, two distribution ducts are fixedly connected to the top of the collection box, inclined nozzles are evenly connected to the bottom of the distribution duct, a blower is installed at one end of the main body, and the output end of the blower is connected to a connecting pipe connected to one end of the distribution duct, which facilitates cleaning debris and shot that fall onto the surface of the workpiece plate.

[0011] Preferably, the control terminals of the blower, the third conveyor, the fourth conveyor, and the elevator are all electrically connected to an external power source via an external switch, which facilitates the operation of this device.

[0012] The operating method of this device is as follows: Step 1: Size adjustment. The user sets the size of the first and second acceleration plates according to the width of the workpiece, controls the electric actuator to work, and moves the sliding ring through the sliding tube, slide plate and slider. The sliding ring causes the second acceleration plate to slide inward into the first acceleration plate, thereby adjusting the spray size. Step 2: Surface treatment. The output end of the motor drives the first and second acceleration plates to rotate at high speed through the rotating ring. At the same time, the shot inside the material box is fed through the first feeder, enters the inside of the discharge pipe through the feed cylinder and sliding tube, and is finally discharged downward through the discharge port. It is accelerated by the rotating first and second acceleration plates and finally sprayed through the bottom of the acceleration box. At this time, the high-speed shot can polish the surface of the workpiece plate and remove impurities from the surface of the workpiece plate. Step 3: Recycling and reuse. The grooving allows the shot to roll towards the collection box. The baffle can scrape off some of the shot and debris from the surface of the workpiece plate. The air generated by the blower enters the air distribution pipe through the connecting pipe and blows the surface of the workpiece plate clean through the nozzle, ensuring that the shot falls into the inside of the collection box. It is filtered by the filter plate and then transported to the bottom of the elevator by the third and fourth feeders. Finally, the elevator lifts the shot and transports it to the inside of the material box for recycling. Step 4: Negative pressure vacuuming. The suction force generated by the negative pressure fan creates a negative pressure state inside the vacuum canister. At this time, the suction force, through the vacuum pipe and vacuum head, can suck away the dust generated during processing. The dust is then filtered through the vacuum canister, and the filtered dust is discharged into the waste cart through the second conveyor for centralized storage. Compared with the prior art, the beneficial effects of the present invention are: When using this device, the user first places the projectile into the material box. The user sets the dimensions of the first and second acceleration plates according to the width of the workpiece. The user controls the electric actuator, which moves the sliding ring via the sliding tube, slide plate, and slider. The sliding ring causes the second acceleration plate to slide inwards towards the first acceleration plate, thus adjusting the spray size. Simultaneously, the sliding tube and slide plate also control the projectile's descent through the discharge port, ensuring the descent size matches the spray size. After setting the dimensions, when the workpiece plate passes through the slot, the motor output drives the first acceleration plate via a rotating ring. The first and second accelerator plates rotate at high speed, while the shot inside the material box is fed through the first feeder, enters the discharge pipe through the feed cylinder and sliding tube, and is finally discharged downwards through the discharge port. Accelerated by the rotating first and second accelerator plates, the shot is finally ejected from the bottom of the accelerator box. At this point, the high-speed shot can grind the surface of the workpiece plate, removing impurities. Because the inner wall of the bottom of the groove is inclined, the shot can roll towards the collection box. Simultaneously, some of the debris remaining on the workpiece plate surface and the shot are scraped off by the baffle as they pass through it, and the blower generates... Air enters the distribution duct through connecting pipes, and finally, the inclined nozzles clean the surface of the workpiece plate, ensuring that the shot falls into the collection box. Large impurities are filtered out by a filter plate, and then the shot is conveyed to the bottom of the elevator via the third and fourth feeders. Finally, the elevator lifts the shot and transports it to the material box for recycling. If there is too much shot in the material box, it will be discharged into the collection box through an overflow pipe to prevent overflow. Simultaneously with the surface treatment of the workpiece plate, the negative pressure suction fan is activated, and negative pressure suction... The suction generated by the machine creates a negative pressure inside the dust collection tank. Under this pressure, the suction pipe and dust head can remove the dust generated during processing. The dust is then filtered through the dust collection tank and discharged into the waste cart via the second conveyor for centralized storage. This device can operate fully automatically without the need for multiple operators. It can not only set different spray sizes according to the size of the workpiece plate to maximize efficiency, but also automatically recycle and reuse the shot, reducing workload. It can also effectively treat the generated dust, ensuring the user's working environment and safety. Attached Figure Description

A dust collection head 30 connected to the dust collection pipe 29 is installed on the inner wall of the through groove 3. When the negative pressure fan 26 is started, the suction force generated by the negative pressure fan 26 makes the inside of the dust collection tank 25 a negative pressure state.

The upper middle part of the 5 is connected to the overflow pipe 40, and the bottom end of the overflow pipe 40 is located at the top of the collection box 31. The bullets fall into the collection box 31 and are filtered by the filter plate 32 to filter out large impurities. The bullets can be conveyed to the bottom end of the elevator 39 by the third feeder 37 and the fourth feeder 38. Finally, the elevator 39 lifts the bullets and conveys them to the inside of the material box 5 for recycling. If there are too many bullets in the material box 5, they will be discharged into the collection box 31 through the overflow pipe 40 to avoid overflow, reduce the user's workload, and improve the utilization rate of bullets. Please see Figure 2 , Figure 6 and Figure 7 In this embodiment, the auxiliary mechanism includes a distribution pipe 33. Two distribution pipes 33 are fixedly connected to the top of the collection box 31. Inclined nozzles 34 are evenly connected to the bottom of the distribution pipes 33. A blower 35 is installed at one end of the main body 1. The output end of the blower 35 is connected to a connecting pipe 36 connected to one end of the distribution pipe 33. The air generated by the blower 35 enters the interior of the distribution pipe 33 through the connecting pipe 36. Finally, the inclined nozzles 34 can blow the surface of the workpiece plate 7 clean, ensuring that the projectiles fall into the interior of the collection box 31, which is convenient for cleaning the debris and projectiles that fall on the surface of the workpiece plate 7. It should be noted that auxiliary roller frames 2 are fixedly connected to both ends of the main body 1, and the height of the auxiliary roller frames 2 is adapted to the height of the through groove 3. Baffles 4 are fixedly connected to both ends of the through groove 3. The first acceleration plate 14 and the connecting rod 11 are distributed at intervals. One end of the conveying cylinder 16 is rotatably connected to a set of rotating rings 10. One end of the feeding pipe 18 is connected to another set of rotating rings 10 through a bearing. The sliding pipe 20 is slidably connected to the feeding pipe 18. The output end of the electric push rod 21 is fixedly connected to one end of the sliding pipe 20 to improve the ease of use of this device. The control ends of the motor 12 and the electric push rod 21 are electrically connected to the external power supply through an external switch to facilitate the operation of this device. The control ends of the negative pressure suction fan 26 and the second feeder 27 are electrically connected to the external power supply through an external switch to facilitate the operation of this device. The control ends of the blower 35, the third feeder 37, the fourth feeder 38 and the elevator 39 are electrically connected to the external power supply through an external switch to facilitate the operation of this device. The device operates as follows: Step 1: Size adjustment. The user sets the size of the first acceleration plate 14 and the second acceleration plate 15 according to the width of the workpiece, controls the electric push rod 21 to work, and moves the sliding ring 13 through the sliding tube 20, the sliding plate 24 and the slider 23. The second acceleration plate 15 slides into the inside of the first acceleration plate 14 through the sliding ring 13, thereby adjusting the spray size. Step 2: Surface treatment. The output end of motor 12 drives the first acceleration plate 14 and the second acceleration plate 15 to rotate at high speed through the rotating ring 10. At the same time, the shot inside the material box 5 is fed through the first feeder 17, enters the inside of the discharge pipe 18 through the feed cylinder 16 and the sliding tube 20, and is finally discharged downward through the discharge port 19. It is accelerated by the rotating first acceleration plate 14 and the second acceleration plate 15, and finally sprayed through the bottom of the acceleration box 8. At this time, the high-speed shot can polish the surface of the workpiece plate 7 and remove impurities from the surface of the workpiece plate 7. Step 3: Recycling and reuse. The groove 3 allows the projectiles to roll towards the collection box 31. The curtain 4 scrapes off some of the projectiles and debris from the surface of the workpiece plate 7. The air generated by the blower 35 enters the air distribution pipe 33 through the connecting pipe 36 and blows the surface of the workpiece plate 7 clean through the nozzle 34, ensuring that the projectiles fall into the collection box 31 and are filtered by the filter plate 32. The third feeder 37 and the fourth feeder 38 can transport the projectiles to the bottom of the elevator 39. Finally, the elevator 39 lifts the projectiles and transports them to the inside of the material box 5 for recycling. Step 4: Negative pressure dust collection. The suction force generated by the negative pressure fan 26 creates a negative pressure state inside the dust collection can 25. At this time, the suction force can remove the dust generated during processing through the dust collection pipe 29 and the dust collection head 30. The dust is filtered through the dust collection can 25 and discharged into the waste cart 28 through the second feeder 27 for centralized storage.

[0017] When using this device, the user first places the projectile into the material box 5. The user sets the dimensions of the first acceleration plate 14 and the second acceleration plate 15 according to the width of the workpiece. The user controls the electric push rod 21 to work, and the output end of the electric push rod 21 extends, pushing the sliding tube 20 to slide inside the feed cylinder 16. One end of the sliding tube 20 drives the slide plate 24 to slide inside the discharge port 19. At the same time, the sliding tube 20 extends into the discharge pipe 18. The sliding tube 20 can block one end of the discharge port 19, thereby adjusting the size of the projectile falling. The slide plate 24 drives the sliding ring 13 to slide on the surface of the connecting rod 11 through the slider 23. At the same time, the sliding ring 13 drives the second acceleration plate 15 to move into the first acceleration plate 14. The movement allows for adjustment of the spray size. Simultaneously, the sliding tube 20 and slide plate 24 control the size of the projectile falling through the discharge port 19, ensuring the falling size matches the spray size. After setting the size, when the workpiece plate 7 passes through the slot 3, the output of the motor 12 drives the rotating ring 10 to rotate. The rotating ring 10 drives the first acceleration plate 14 and the second acceleration plate 15 to rotate at high speed. Simultaneously, the slider 23 slides inside the slot 22. The projectile inside the material box 5 is fed by the first feeder 17, enters the discharge pipe 18 through the feed cylinder 16 and sliding tube 20, and finally exits downwards through the discharge port 19. The rotating first acceleration plate 14 and second acceleration plate 15 accelerate the projectile inside the acceleration box 8. Finally, the projectiles are ejected from the bottom of the acceleration box 8. At this point, the high-speed projectiles can grind the surface of the workpiece plate 7 and remove impurities from the surface of the workpiece plate 7. Since the inner wall of the bottom of the through groove 3 is inclined, the projectiles can roll towards the collection box 31. At the same time, the debris remaining on the surface of the workpiece plate 7 and the projectiles are scraped off by the baffle 4 when they pass through the baffle 4. The air generated by the blower 35 enters the interior of the air distribution pipe 33 through the connecting pipe 36. Finally, the inclined nozzle 34 can blow the surface of the workpiece plate 7 clean, ensuring that the projectiles fall into the interior of the collection box 31. They are filtered by the filter plate 32 to filter out large debris. The projectiles can be transported to the bottom of the elevator 39 by the third feeder 37 and the fourth feeder 38. Finally, the projectiles are transported by the elevator 39. 9. The projectiles are conveyed to the material bin 5 for recycling. If there are too many projectiles in the material bin 5, they will be discharged into the collection bin 31 through the overflow pipe 40 to prevent overflow. While the workpiece plate 7 is being treated, the negative pressure suction fan 26 is started. The suction force generated by the negative pressure suction fan 26 creates a negative pressure state inside the dust collection tank 25. At this time, the suction force can suck away the dust generated during the process through the suction pipe 29 and the suction head 30. The dust is filtered through the dust collection tank 25 and discharged into the waste cart 28 through the second conveyor 27 for centralized storage. This device can work fully automatically without the need for multiple operators. It can not only set different spray sizes according to the size of the workpiece plate 7, but also maximize efficiency.It can also automatically recover and reuse projectiles, reducing workload, and effectively treat the generated dust, ensuring the user's working environment and safety.

A marine profile shot blasting device according to claim 6, characterized in that: The auxiliary mechanism includes a distribution pipe (33), two distribution pipes (33) are fixedly connected to the top of the collection box (31), and inclined nozzles (34) are evenly connected to the bottom of the distribution pipe (33). A blower (35) is installed at one end of the main body (1), and a connecting pipe (36) connected to one end of the blower (35) is connected to the output end of the blower (35).

8. A marine profile shot blasting device according to claim 7, characterized in that: The control terminals of the blower (35), the third feeder (37), the fourth feeder (38) and the elevator (39) are all electrically connected to an external power source via an external switch.

9. A method for operating the marine profile shot blasting device as described in claim 8, characterized in that: Step 1: Size adjustment. The user sets the size of the first acceleration plate (14) and the second acceleration plate (15) according to the width of the workpiece, controls the electric push rod (21) to work, and makes the sliding ring (13) move through the sliding tube (20), the sliding plate (24) and the slider (23). The second acceleration plate (15) slides into the inside of the first acceleration plate (14) through the sliding ring (13), thereby adjusting the spray size. Step 2: Surface treatment. The output end of the motor (12) drives the first acceleration plate (14) and the second acceleration plate (15) to rotate at high speed through the rotating ring (10). At the same time, the shot inside the material box (5) is fed through the first feeder (17), enters the inside of the discharge pipe (18) through the feed cylinder (16) and the sliding tube (20), and is finally discharged downward through the discharge port (19). It is accelerated by the rotating first acceleration plate (14) and the second acceleration plate (15), and finally sprayed through the bottom of the acceleration box (8). At this time, the high-speed shot can polish the surface of the workpiece plate (7) and remove impurities from the surface of the workpiece plate (7). Step 3: Recycling and reuse. The groove (3) allows the projectile to roll toward the collection box (31). The curtain (4) scrapes off some of the projectile and debris on the surface of the workpiece plate (7). The air generated by the blower (35) enters the air distribution pipe (33) through the connecting pipe (36). The nozzle (34) blows the surface of the workpiece plate (7) clean, ensuring that the projectile falls into the inside of the collection box (31). It is filtered by the filter plate (32). The third feeder (37) and the fourth feeder (38) can transport the projectile to the bottom of the elevator (39). Finally, the elevator (39) lifts the projectile and transports it to the inside of the material box (5) for recycling. Step 4: Negative pressure dust collection. The suction force generated by the negative pressure fan (26) makes the inside of the dust collection can (25) negative pressure. At this time, the suction force can remove the dust generated during processing through the dust collection pipe (29) and the dust collection head (30). The dust is filtered through the dust collection can (25), and the filtered dust is discharged into the inside of the waste cart (28) through the second feeder (27) for centralized storage.
