DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-4 , the specific implementation methods of the utility model are further described in detail to make the technical solution of the utility model easier to understand and grasp.

[0031] The embodiment of the present application discloses a shot blasting machine with a leakage prevention mechanism:

[0032] Reference Figures 1-4 A shot blasting machine with a leakage prevention mechanism includes a shot blasting structure 1 and a shot blasting box 2 with a door panel 21. Multiple pulleys 22 rotate in the shot blasting box 2. The multiple pulleys 22 are staggered up and down and connected by the same crawler 23. The crawler 23 is concave. The shot blasting structure 1 is fixed above the concave part of the crawler 23. It also includes a leakage prevention mechanism 3. The leakage prevention mechanism 3 includes a movable rod 31 and a driving structure 32. The movable rod 31 slides on the surface of the concave part of the crawler 23 through the driving structure 32. The sliding trajectory of the movable rod 31 fits with the concave part of the crawler 23. When the material is unloading operation is carried out, the driving structure 32 drives the movable rod 31 to scrape the concave part of the crawler 23 in parallel, thereby scraping the workpiece out of the shot blasting box 2, reducing the situation where the workpiece is trapped in the concave part of the crawler 23 and increasing the working stability.

[0033] Referring to Figure 4 , the drive structure 32 includes a drive rod 33 and a motor 34. The crawler 23 is recessed to form an arc, and the motor 34 is fixed at the center of the arc. One end of the drive rod 33 is fixed to the output end of the motor 34 and rotates around the motor 34. The ends of the two drive rods 33, away from the motor 34, are fixed to either side of the movable rod 31. The motor 34 drives the drive rod 33, which in turn drives the movable rod 31 to rotate in close contact with the crawler 23, ensuring smooth movement and stability during operation.

[0034] Reference Figure 3-Figure 4 Baffles 4 are also fixed at both ends of the crawler 23. The baffles 4 are circular and have a clearance groove 41 at one end of the contact surface between the baffle 4 and the crawler 23. The width of the clearance groove 41 is slightly larger than the diameter of the drive rod 33. The design of the baffle 4 reduces the possibility of workpieces and shot blasting hitting the motor 34 and drive rod 33, ensuring safety during the shot blasting cleaning process.

[0035] Reference Figure 1-Figure 2 , further comprising a feeding structure 5, which includes a feeding box 51 with a discharge port 511 and a hydraulic flip structure 52. The hydraulic flip structure 52 is used to abut the discharge port 511 of the feeding box 51 against the crawler 23. The hydraulic flip structure 52 ensures the accurate docking of the discharge port 511 of the feeding box 51 with the crawler 23, prevents the workpiece from falling, and ensures the continuity and stability of the feeding process.

[0036] Reference Figure 2 The hydraulic turning structure 52 includes a turntable 521 with a turning rod 522 and a cylinder 523. The feeding box 51 is rotated on the turntable 521 by the turning rod 522. The length direction of the turning rod 522 is parallel to the width direction of the feeding box 51. The turntable 521 is located outside the shot blasting box 2. The cylinder 523 rotates below the turning rod 522. The telescopic rod of the cylinder 523 is set toward the feeding box 51. The telescopic rod of the cylinder 523 is fixedly connected to the feeding box 51. When the telescopic rod of the cylinder 523 is extended, the feeding box 51 rotates in the direction of abutting against the crawler 23 toward the discharge port 511. The cylinder 523 is retracted to drive the turntable 521 to rotate, making the turning process of the feeding box 51 smooth and preventing the workpieces from falling. At the same time, the cylinder 523 controls the turning process, reducing the labor intensity of the operator and improving work efficiency.

[0037] Reference Figure 2 , further comprising a material discharge structure 6, which comprises a material discharge chute 61 with a material discharge port 62 and a vibration motor 63. The material discharge chute 61 is located directly below the door panel 21, and the vibration motor 63 is fixed below the material discharge chute 61. When discharging, the track 23 transports the workpiece outward and directly drops it onto the material discharge chute 61. The vibration motor 63 transports the workpiece in the material discharge chute 61 to the material discharge port 62 through vibration. A collection box 64 is also placed below the material discharge port 62 for collecting workpieces after shot blasting. After the track 23 transports the workpiece to the material discharge chute 61, the vibration motor 63, through vibration, transports the workpiece in the material discharge chute 61 to the material discharge port 62 in a direction, ensuring the continuity and stability of the material discharge process. At the same time, the vibration discharge method is fast and efficient, shortening the workpiece transportation time, and can effectively prevent the workpiece from getting stuck in the chute, ensuring that the workpiece falls smoothly into the collection box 64.

[0038] Reference Figure 3 The crawler 23 is provided with a plurality of leakage holes for the shot to pass through. A collection trough 7 is also provided under the crawler 23 for collecting the shot. At the same time, an opening and closing plate is hinged on the side of the shot blasting machine to facilitate the operator to take the collection trough 7. The leakage holes allow the shot to pass through the crawler 23 and fall into the collection trough 7, thereby realizing the recovery and reuse of the shot and reducing the cost of consumables.

[0039] Reference Figure 1-Figure 3, also includes a negative pressure exhaust structure 8, which can extract dust and debris from the shot blasting box 2 and remove impurities, thereby ensuring that the debris does not affect the use of the workpiece in the shot blasting box 2 and extending the service life of the workpiece.

[0040] An automatic shot loading structure can also be designed at the collection trough 7, and the shot can be transported to the elevator through a pipeline, and then the elevator lifts the shot and transports it to another pipeline connected to the shot blasting structure 1, so as to realize automatic shot loading and increase work efficiency.

[0041] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
