Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to a double-hook shot blasting cleaning machine. Background Art

[0002] The prior art discloses a novel double-hook shot blasting cleaning machine (CN202220389792.6), comprising a supporting base plate, wherein a spiral conveying cleaning box and a dust collector are fixedly arranged on both sides of the upper surface of the supporting base plate, arc grooves are provided on both sides of the upper end surface of the spiral conveying cleaning box near the front end, and synchronous cylinders are fixedly arranged on the upper end surface of the spiral conveying cleaning box near the edges on both sides, and a top plate is fixedly arranged on the upper ends of the two synchronous cylinders, and a connecting flange is fixedly arranged at the center of the upper surface of the top plate by a plurality of fixing bolts, and a No. 1 protective shell is fixedly arranged on the upper end of the connecting flange, and a No. 2 motor is fixedly arranged inside the No. 1 protective shell, and a No. 2 rotating rod is fixedly arranged at the output end of the No. 2 motor.

[0003] The prior art improves efficiency by setting two hooks to alternately convey workpieces, and the hooks enter and exit the machine body from the top. If a normally open design is adopted, steel balls will splash and dust will escape during the shot blasting process. If a baffle is used to block the opening on the top of the machine body, the entry and exit of the workpieces will be subject to certain interference. It is inconvenient to repeatedly push the cover plate with the baffle at the top, and it is necessary to climb up to reach the baffle. There is a certain room for optimization in the way that the cover plate moves and blocks the opening on the top of the machine body.

[0004] For this reason, we propose a double-hook shot blasting machine. Utility Model Content

[0015] 1. A double-hook shot blasting cleaning machine, by setting a frame, two baffles sliding on the top surface of the frame are inclined and distributed. In the absence of external force, they will slide towards each other until they fit together to cover the top opening of the shot blasting machine body, and the wall surfaces of the two baffles are provided with rectangular grooves for avoiding cables. When the hook hoists the workpiece into the cavity of the shot blasting machine body, the toggle rod can be pushed to flip and drive the corresponding baffle to slide along the top of the frame, so that the two baffles move away from each other, and the workpiece can be placed between the two baffles.

The top of the shot blasting machine body 10 is provided with a shielding structure for sealing the opening. The shielding structure includes a frame 20, a baffle 21 and a toggle rod 22. The frame 20 is fixedly connected to the shot blasting machine body 10. The top of the frame 20 is slidably connected to two baffles 21 distributed inwardly eight. The side wall of the shot blasting machine body 10 is rotatably connected to the two toggle rods 22. The two baffles 21 are movably connected to the corresponding toggle rods 22. The toggle rods 22 are flipped to push the corresponding baffles 21 to slide along the top surface of the frame 20 to expose the opening of the shot blasting machine body 10. The frame 20 forms a rectangular frame structure. A V-shaped notch is provided on the top surface of the frame 20. The two baffles 21 are both slidably connected to the top inclined surface of the frame 20 and the two baffles 21 conflict with each other. The toggle rod 22 forms an L-shaped rod structure. The two toggle rods 22 are outwardly Eight distribution, by setting the frame 20, the two baffles 21 sliding on the top surface of the frame 20 will slide towards each other due to the inclined distribution without the action of external force until they fit together to cover the top opening of the shot blasting machine body 10, and the wall surfaces of the two baffles 21 are provided with rectangular grooves for avoiding cables. When the hook hoisting workpiece enters the cavity of the shot blasting machine body 10, the toggle rod 22 can be pushed to flip and drive the corresponding baffle 21 to slide along the top of the frame 20, so that the two baffles 21 move away from each other, and the workpiece can be placed between the two baffles 21. After the workpiece enters, the toggle rod 22 can be released, and the baffle 21 can be reset under gravity to cover the opening at the top of the shot blasting machine body 10, thereby reducing the escape of dust during the shot blasting process. It has the characteristics of sealing the chamber of the shot blasting machine body 10 and not interfering with the workpiece entering and exiting the chamber of the shot blasting machine body 10. It is easy to operate and flexible to use.

[0026] like Figure 4 As shown, the shielding structure also includes a limit groove 23 and a connecting column 24. The wall surface of each toggle rod 22 is provided with the same limit groove 23. The connecting column 24 is located in the limit groove 23 and is fixedly connected to the baffle 21. The limit groove 23 forms a rectangular notch. The connecting column 24 is cylindrical. The diameter of the connecting column 24 is smaller than the width of the limit groove 23. The end of the connecting column 24 is fixedly connected to the side wall surface of the baffle 21. By providing the limit groove 23 and utilizing the limit groove 23 to limit the connecting column 24, when the toggle rod 22 is flipped, the connecting column 24 can slide in the limit groove 23 and be pushed by the toggle rod 22, so that the connecting column 24 can drive the baffle 21 to slide along the top of the frame 20, thereby ensuring the stability of the movement of the baffle 21 and reducing interference.

[0027] like Figure 5As shown, the shielding structure also includes a side plate 30, a pedal 31 and a limiting column 32. The side plate 30 is fixedly connected to the shot blasting machine body 10. The pedal 31 is slidably connected to the side plate 30 through the limiting column 32. A cable is provided between the pedal 31 and the toggle rod 22. A limiting hole is provided on the wall surface of the side plate 30. The limiting column 32 slides in the limiting hole.

The two free ends of the cable are fixedly connected to the nose ring of the toggle rod 22 and the wall surface of the pedal 31, respectively. Fixed connection, in this scheme, as a supplement to the above scheme, by setting a pedal 31, when you want to push the baffle 21 to slide, you can press the pedal 31 with your hand or foot, and the pedal 31 drives the limit column 32 to slide vertically along the side plate 30, and the pedal 31 will pull the cable and then pull the two toggle rods 22 closer to each other, thereby pushing the baffle 21, and the outer wall of the shot blasting machine body 10 is also rotatably connected to the roller guiding the cable, which can push the two toggle rods 22 to flip at the same time, which is more convenient to push the two baffles 21 to slide at the same time, and it is easier to miss.

[0028] The working principle of the utility model is as follows: the pedal 31 is pressed down by the hand or foot, and the pedal 31 drives the limiting column 32 to slide vertically along the side plate 30, and the pedal 31 will pull the cable and then pull the two toggle rods 22 closer to each other, and the limiting groove 23 is used to limit the connecting column 24. When the toggle rod 22 is flipped, the connecting column 24 can slide in the limiting groove 23 and be pushed by the toggle rod 22, so that the connecting column 24 can drive the baffle 21 to slide along the top of the frame 20. The two baffles 21 move away from each other, and the workpiece can be placed between the two baffles 21. After the workpiece enters, the toggle rod 22 can be released, and the baffle 21 can be reset under gravity to cover the opening at the top of the shot blasting machine body 10, thereby reducing the escape of dust during the shot blasting process and will not interfere with the workpiece entering and exiting the shot blasting machine body 10.
