[0002] Shot blasting machine is a common type of processing equipment. It mainly uses high-speed projectiles thrown by the shot blaster to clean or strengthen the surface of castings. The machine body can process more castings at one time. After processing, it will be unloaded, and the unloading mechanism of the shot blasting machine will be used.

[0003] After consulting the literature, it is learned that the currently published patent: CN219882229U discloses a shot blasting machine unloading mechanism including a bottom plate, a mounting plate welded and installed on the top of the bottom plate, the number of mounting plates is two groups and they are arranged in parallel and corresponding manner, the corresponding side walls of the mounting plates are provided with unloading conveying mechanisms, and a movable opening is opened on the front side wall of one group of mounting plates. By arranging the unloading conveying mechanism in conjunction with the steel shot collecting mechanism, the device can effectively separate the workpiece from the steel shot automatically, avoiding the situation where the steel shot and the workpiece are mixed together and the staff need to manually separate the workpiece from the steel shot.

[0004] However, the following problems will arise during the use of this solution: when the steel shots and workpieces are unloaded after processing, the waste slag generated by the processing will be unloaded together with the steel shots and the workpieces, making it easy for the waste slag to adhere to the surface of the steel shots. Since there is no waste slag separation device in the device, the staff needs to manually separate and clean the steel shots from the waste slag after collection, which increases the labor intensity of the staff to a certain extent. In view of the above situation, technical innovation is carried out on the basis of the existing device. Utility Model Content

[0019] See also Figure 1-4, the present utility model provides a technical solution: a quantitative feeding structure for a shot blasting machine, including an equipment body 1. The equipment body 1 is an existing structure and will not be elaborated here. The equipment body 1 can separate steel shots and workpieces. A maintenance groove 4 is opened on one side of the equipment body 1. Two symmetrical rotating shafts 7 are rotatably connected inside the equipment body 1. Fixedly connected to the opposite sides of the two rotating shafts 7 are transmission frames 8. The cross-section of the transmission frame 8 is in a C shape. A connecting shaft 9 is fixedly connected between the two transmission frames 8. The two transmission frames 8 can be connected through the connecting shaft 9. A motor 21 is fixedly connected to the rear side of the equipment body 1. The motor 21 is an existing structure and will not be elaborated here. The output end of the motor 21 rotates through the rear side of the equipment body 1 and extends into the interior of the equipment body 1. The output end of the motor 21 is fixedly connected to the surface of the rotating shaft 7. A collecting box 5 is arranged inside the equipment body 1. The collecting box 5 can collect steel shots. Two symmetrical T-shaped frames 10 are fixedly connected to the top of the collecting box 5. An activity groove 19 is opened inside the T-shaped frame 10. The surface of the transmission frame 8 is movably connected to the interior of the activity groove 19. The transmission frame 8 can rotate and move inside the activity groove 19. A first collecting groove 13 communicating with the inside of the collecting box 5 is opened on the front side of the collecting box 5. A first collecting frame 11 is slidably connected inside the first collecting groove 13. Mesh holes are opened on the bottom plate of the first collecting frame 11. Through the mesh holes on the bottom plate of the first collecting frame 11, steel shots and waste residues can be separated.

[0020] Furthermore, a second collecting groove 14 communicating with the inside of the collecting box 5 is opened on the front side of the collecting box 5. A second collecting frame 12 is slidably connected inside the second collecting groove 14. The second collecting frame 12 can collect the separated waste residues.

[0021] After the equipment body 1 is started by the staff, after the equipment body 1 separates the steel shots and workpieces, the steel shots fall into the interior of the collecting box 5 under the restriction of the inclined plate 20. The staff starts the chute 6 through an external control device. The chute 6 drives the transmission frame 8 and the connecting shaft 9 to rotate through the rotating shaft 7. Due to the C-shaped cross-section of the transmission frame 8 and the restriction of the limiting plate 16, the rotating shaft 7 can drive the T-shaped frame 10 to move up and down through the transmission frame 8, so that the collecting box 5 can shake up and down. At the same time, through the mesh holes on the bottom plate of the first collecting frame 11, steel shots and waste residues can be separated, making the collection of steel shots more convenient and the cleaning of steel shots more convenient. There is no need for manual cleaning and manual shot cleaning, improving the safety of equipment use and making it more convenient for the staff to use the device.

[0022] Furthermore, two symmetrical inclined plates 20 are fixedly connected inside the equipment body 1. The inclined plates 20 are arranged obliquely inside the equipment body 1. Due to the inclined setting of the equipment body 1, the steel shots can more smoothly enter the interior of the collecting box 5 for collection.

[0023] Furthermore, two symmetrical limit plates 16 are fixedly connected inside the equipment body 1, and the collecting box 5 is located between the two limit plates 16. The limit plates 16 can limit the moving direction of the collecting box 5, and the limit plates 16 can move up and down more smoothly, so that the steel shots can be separated from the waste slag more smoothly.

[0024] Furthermore, a box body 2 is fixedly connected to the top of the equipment body 1, and the box body 2 can hold steel shots and workpieces. A slide groove 6 is opened on the top of the box body 2, and a first baffle 3 is slidably connected inside the slide groove 6. The cross-section of the first baffle 3 is a cross, and the steel shots and workpieces can be blocked by the first baffle 3. The lower surface inside the box body 2 is an inclined surface, and the box body 2 can be used to quantify the unloaded steel shots and workpieces, so that the equipment body 1 can separate the quantified steel shots and reduce the unquantified steel shots and workpieces to a certain extent, so that the equipment body 1 is more difficult to separate more steel shots from the workpiece, so that the staff can use the device more conveniently.

[0025] Furthermore, a rotating groove 18 is opened on the front side of the collecting box 5, and the internal rotating groove 18 is rotatably connected with a retaining frame 15 extending to the outside of the rotating groove 18. The cross-section of the retaining frame 15 is L-shaped, and the positions of the first collecting frame 11 and the second collecting frame 12 can be positioned and fixed by the retaining frame 15. A torsion spring 17 is fixedly connected to one side of the retaining frame 15, and the torsion spring 17 is movably sleeved on the retaining frame 15. The end of the torsion spring 17 away from the retaining frame 15 is fixedly connected to the inner wall of the rotating groove 18. The torsion spring 17 can be compressed and reset by the rotation of the retaining frame 15. When the staff rotates the retaining frame 15 to be parallel to the first collecting frame 11, the retaining frame 15 releases the positioning of the first collecting frame 11 and the second collecting frame 12, so that the first collecting frame 11 and the second collecting frame 12 can slide out more smoothly, and the staff can more smoothly take out the separated steel shots and waste slag.

[0026] Working principle: For this type of shot blasting machine with quantitative feeding structure, the staff first starts the equipment body 1, and after the equipment body 1 separates the steel shot from the workpiece, the steel shot falls into the collection box 5 under the restriction of the inclined plate 20. The staff starts the chute 6 through the external control device, and the chute 6 drives the transmission frame 8 and the connecting shaft 9 to rotate through the rotating shaft 7. The cross-section of the transmission frame 8 is in the shape of a Chinese character and the restriction of the limit plate 16, so that the rotating shaft 7 can drive the T-shaped frame 10 to move up and down through the transmission frame 8, so that the collection box 5 can enter. The first collecting frame 11 is swayed up and down, and the mesh holes on the bottom plate of the first collecting frame 11 can separate the steel shots from the waste slag, making the collection of the steel shots more convenient and the cleaning of the steel shots more convenient without manual cleaning and manual shot cleaning. When the staff rotates the baffle 15 to be parallel to the first collecting frame 11, the baffle 15 releases the positioning of the first collecting frame 11 and the second collecting frame 12, so that the first collecting frame 11 and the second collecting frame 12 can slide out more smoothly, and the staff can take out the separated steel shots and waste slag more smoothly.
