Technical Field

[0001] This invention relates to the field of shot blasting equipment technology, specifically to a circulating tracked shot blasting equipment and its usage method. Background Technology

[0002] Shot blasting equipment is a specialized surface treatment device that uses a high-speed rotating shot blaster to directionally and at high speed propel abrasive materials such as steel shot and iron shot onto the surface of a workpiece. It is often used in conjunction with dust removal, conveying, and sealing protection structures as a complete set. It is mainly used for rust removal, oxide scale removal, casting sand removal, surface strengthening, and burr removal of metal workpieces.

[0003] In existing shot blasting equipment, the workpieces to be processed are usually poured directly onto the conveyor belt surface by hand during loading. This causes the weight of the workpieces and the acceleration due to gravity to directly impact the track surface. After prolonged use, this can easily damage the track surface and reduce the service life of the track. Summary of the Invention

[0010] Preferably, the adjusting component includes a turntable, the interior of which is fixedly connected to the end of the transmission rod away from the fan blade, and a plurality of centrifugal blocks are slidably connected inside the turntable, with elastic elements fixedly provided on the outer wall of the centrifugal blocks.

[0011] Preferably, the turntable has multiple grooves inside, and the size of the grooves is adapted to the centrifugal block.

[0012] Preferably, the fixed frame has multiple sliding grooves inside, and the storage box is slidably connected to the sliding grooves.

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see the appendix Figure 1 - Appendix Figure 3 This invention provides a circulating tracked shot blasting equipment, including a tracked conveyor 1. A shot blasting machine 2 is fixedly installed on the outer wall of the tracked conveyor 1. A through pipe 3 is installed inside the shot blasting machine 2 and connected to an external dust collector. A fixed frame 4 is fixedly connected to the outer wall of the tracked conveyor 1 away from the shot blasting machine 2. A motor 5 is fixedly installed on the outer wall of the fixed frame 4. A rotating rod 6 is fixedly installed at the drive end of the motor 5. A traction rope 7 is fixedly connected to the outer wall of the rotating rod 6. A storage box 12 is fixedly installed at the end of the traction rope 7 away from the rotating rod 6. A plurality of gears 8 are fixedly connected to the outer wall of the storage box 12. The teeth of the gears 8 are meshed with toothed plates 9. An air guiding assembly 10 is installed in the middle of the rotating rod 6. The air guiding assembly 10 includes an air bladder 104. A buffer pad 23 is fixedly connected inside the air bladder 104 through an external air guiding pipe.

[0023] Specifically, the dust collector, the elevator in shot blasting machine 2, the shot blaster in shot blasting machine 2, and the crawler conveyor 1 are started sequentially through the main control equipment. The crawler conveyor 1 is made of wear-resistant rubber, which can not only bear heavy workpieces but also prevent steel shot from getting stuck and damaging the roller surface. The inlet and outlet of shot blasting machine 2 are equipped with multi-layer sealed brushes and rubber curtains to effectively prevent steel shot splashing and dust leakage. First, the workpiece to be processed is poured into the storage box 12. Then, the motor 5 is turned on to drive the rotating rod 6 to rotate inside the fixed frame 4, further winding the traction rope 7. When the rotating rod 6 winds the traction rope 7, it will cause the storage box 12 to slide upward inside the fixed frame 4. When in operation, the storage box 12 and the gear 8 are fixed together, which drives the gear 8 to move upward synchronously. After the gear 8 moves upward a certain distance, it will mesh with the toothed plate 9, which will further drive the storage box 12 to flip over, so that the workpiece to be processed can be poured onto the crawler conveyor 1. While the rotating rod 6 is rotating, it will also inflate the buffer pad 23 through the air guide component 10. This achieves automatic feeding of the workpiece to be processed, which reduces the workload of the workers. At the same time, the automatic inflation of the buffer pad 23 through the air guide component 10 can prevent the workpiece to be processed from directly hitting the surface of the crawler conveyor 1, thereby preventing damage to the crawler conveyor 1 and improving the service life of the crawler conveyor 1.

[0024] Please see the appendix Figure 1 - Appendix Figure 3 The air guiding assembly 10 also includes a threaded rod 101. The outer wall of the threaded rod 101 is fixedly connected to the middle of the rotating rod 6. A threaded block 102 is threadedly connected to the outer wall of the threaded rod 101. A housing 103 is slidably connected to the outer wall of the threaded block 102. The side of the threaded block 102 away from the motor 5 is attached to the outer wall of the airbag 104. The airbag 104 is installed inside the housing 103. A limit rod 11 is slidably connected inside the threaded block 102. The outer wall of the limit rod 11 is fixedly connected to the inside of the fixing frame 4. The housing 103... The internal fixed connection is to the outer wall of the limiting rod 11; the internal of the fixed frame 4 is provided with multiple sliding grooves, and the storage box 12 is slidably connected to the sliding grooves; the outer wall of the rotating rod 6 is rotatably connected to the internal of the fixed frame 4, the outer wall of the storage box 12 is slidably connected to the internal of the fixed frame 4, the outer wall of the toothed plate 9 is fixedly connected to the outer wall of the fixed frame 4, the lower surface of the buffer pad 23 is fixedly connected to the upper surface of the crawler conveyor 1, the internal of the outer shell 103 is provided with multiple sliding grooves, and the threaded block 102 is slidably connected to the internal of the outer shell 103 through the sliding grooves.

[0025] Specifically, when the rotating rod 6 rotates, the fixing action of the rotating rod 6 and the threaded rod 101 will drive the threaded rod 101 to rotate synchronously, further driving the threaded block 102 connected to its outer wall to slide on the outer wall of the limiting rod 11. After sliding a certain distance, the threaded block 102 will slide into the interior of the outer shell 103 through multiple grooves opened inside the outer shell 103, further squeezing the airbag 104 installed inside the outer shell 103, and the gas generated by squeezing the airbag 104 will be transported to the interior of the buffer pad 23 through the external air guide pipe. Thus, when the storage box 12 is unloading, the buffer pad 23 will move and buffer the workpiece to be processed to prevent it from directly hitting the surface of the crawler conveyor 1. At the same time, when not in use, there is no gas in the buffer pad 23, which prevents the buffer pad 23 from always being in an expanded state, which would increase the corrosion damage to its surface caused by the external environment and reduce the service life of the buffer pad 23. The groove opened inside the fixing frame 4 is used to limit the movement trajectory of the storage box 12, thereby improving the stability of the storage box 12 when it moves.

[0026] Please see the appendix Figure 1 Appendix Figure 4 and attached Figure 5 Inside the pipe 3, a fan blade 13 is rotatably connected. Inside the fan blade 13, a transmission rod 14 is fixedly connected. The outer wall of the transmission rod 14 is rotatably connected inside the pipe 3. An electrostatic adsorption roller 15 is fixedly connected to the outer wall of the transmission rod 14. The electrostatic adsorption roller 15 and the pipe 3 rub against each other to generate static electricity. A filter plate 16 is rotatably connected to the outer wall of the transmission rod 14. A reciprocating screw 18 is fixedly connected to the outer wall of the transmission rod 14. A guide plate 19 is threadedly connected to the outer wall of the reciprocating screw 18. A limit rod 20 is slidably connected inside the guide plate 19. The outer wall of the limit rod 20 is fixedly connected to the inner wall of the pipe 3. Multiple push rods 21 are fixedly connected to the outer wall of the guide plate 19. The push rods 21 correspond one-to-one with the holes opened inside the filter plate 16. Multiple rubber rings 22 are installed inside the filter plate 16. The rubber rings 22 have cross-shaped openings inside.

[0027] Specifically, when the external dust collector is turned on to clean the gas generated during operation, the gas flow rate drives the fan blades 13 to rotate inside the pipe 3, which in turn drives the transmission rod 14 to rotate. As the transmission rod 14 rotates, the fixed action between the transmission rod 14 and the electrostatic adsorption roller 15 causes the electrostatic adsorption roller 15 to rotate inside the pipe 3. During this rotation, the friction between the electrostatic adsorption roller 15 and the pipe 3 generates static electricity. This static electricity, generated by the rotation of the electrostatic adsorption roller 15 and the filter plate 16, along with the rotation of the transmission rod 14, and the fixed action between the transmission rod 14 and the reciprocating screw 18, drives the reciprocating screw 18 to rotate... The rotation further drives the guide plate 19, which is threadedly connected to its outer wall, to slide on the outer wall of the limiting rod 20. When the guide plate 19 slides, the fixing action of the guide plate 19 and the top rod 21 will drive the top rod 21 to move synchronously. After the top rod 21 moves a certain distance, it will slide into the interior of the filter plate 16 through the multiple filter holes opened inside the filter plate 16. At this time, the gas breaks through the rubber ring 22 and continues to flow. Thus, while efficiently filtering larger and smaller impurities in the gas, the top rod 21 can also automatically clean the filter holes in the filter plate 16, preventing larger impurities in the gas from clogging the filter holes in the filter plate 16, and ensuring that the filtration operation can be carried out normally and stably.

[0028] Please see the appendix Figure 4 and attached Figure 5 An adjustment component 17 is installed at the end of the transmission rod 14 away from the fan blade 13. The adjustment component 17 is used to adjust the gas flow rate inside the pipe 3. The adjustment component 17 has multiple through holes inside. The adjustment component 17 includes a turntable 171. The turntable 171 is fixedly connected to the end of the transmission rod 14 away from the fan blade 13. Multiple centrifugal blocks 172 are slidably connected inside the turntable 171. Elastic elements 173 are fixedly provided on the outer wall of the centrifugal blocks 172. Multiple grooves are opened inside the turntable 171, and the size of the grooves is adapted to the centrifugal blocks 172.

[0029] Specifically, when the gas flow rate inside the pipe 3 is too high, the fan blade 13 rotates faster, further increasing the rotation rate of the turntable 171 and its internal centrifugal block 172. When the centrifugal force generated by the centrifugal block 172 exceeds the deformation threshold of the elastic element 173, the centrifugal block 172 will slide inside the turntable 171, adaptively sealing the multiple grooves inside. The elastic element 173 can be a steel leaf spring, a coil spring, a torsion bar spring, a rubber spring, etc., preferably a coil spring. By adaptively adjusting the gas flow rate and velocity, the effect of avoiding the electrostatic adsorption roller 15 being unable to efficiently adsorb and filter fine particulate impurities in the gas due to the fast gas flow is achieved.

[0030] Please see the appendix Figure 1 - Appendix Figure 5 A method for using a circulating tracked shot blasting equipment, the method comprising the following steps: S1. The dust collector, the elevator in shot blasting machine 2, the shot blaster in shot blasting machine 2 and the crawler conveyor 1 are turned on in sequence through the main control equipment. S2. Pour the workpiece to be processed into the storage box 12, start the motor 5 to drive the rotating rod 6 to rotate, and wind up the traction rope 7 to pull the storage box 12 to slide upward along the fixed frame 4. S3, the storage box 12 drives the gear 8 to move upward and mesh with the toothed plate 9, causing the storage box 12 to flip and pour the workpiece onto the crawler conveyor 1; S4. Rotating rod 6 synchronously drives threaded rod 101 to rotate, drives threaded block 102 to slide and squeeze airbag 104, airbag 104 inflates into buffer pad 23 to buffer the falling workpiece; S5. After the dust collector is started, the airflow in the pipe 3 drives the fan blades 13, transmission rod 14 and electrostatic adsorption roller 15 to rotate, which in turn filters the waste gas impurities with the filter plate 16. S6, the transmission rod 14 drives the reciprocating screw 18 to rotate, so that the guide plate 19 drives the top rod 21 to reciprocate to clean the filter holes of the filter plate 16; S7. When the flow velocity in the pipe 3 is too high, the transmission rod 14 drives the turntable 171 and centrifugal block 172 to rotate at high speed. The centrifugal block 172 overcomes the elastic force of the elastic element 173 and slides, adaptively sealing the groove of the turntable 171.

[0031] Working process: When the rotating rod 6 rotates, it drives the threaded rod 101 to rotate synchronously, which in turn drives the threaded block 102 to slide along the outer wall of the limiting rod 11. After sliding a certain distance, the threaded block 102 will slide into the inner shell 103, further squeezing the airbag 104. The gas generated by the airbag 104 is sent into the buffer pad 23 through the air guide pipe. Thus, when the storage box 12 is emptying, the buffer pad 23 can buffer the impact of the falling workpiece and prevent the workpiece from directly hitting the surface of the crawler conveyor 1. At the same time, when the equipment is idle, there is no gas inside the buffer pad 23, which avoids long-term expansion, aggravates environmental corrosion, and extends the service life of the buffer pad 23.

[0032] When the dust collector purifies the waste gas generated during operation, the airflow speed drives the fan blades 13 inside the pipe 3 to rotate, which in turn drives the transmission rod 14 to operate. When the transmission rod 14 rotates, it drives the electrostatic adsorption roller 15 to rotate synchronously. The electrostatic adsorption roller 15 generates static electricity through friction with the pipe 3, which, together with the filter plate 16, adsorbs and filters large and small particles of impurities in the gas. At the same time, the rotation of the transmission rod 14 also drives the reciprocating screw 18 to rotate, which further causes the guide plate 19 to slide along the limit rod 20 and drives the top rod 21 to move and insert into the filter hole of the filter plate 16. The gas can push open the rubber ring 22 and flow normally. Thus, it can not only efficiently filter large and small particles of impurities in the gas through the electrostatic adsorption roller 15 and the filter plate 16, but also automatically clean the filter hole of the filter plate 16 by the top rod 21 to prevent impurities from clogging the filter hole, thus ensuring the stable and continuous operation of gas filtration.

[0033] When the gas flow rate inside the pipe 3 is too high, the fan blade 13 rotates faster, further increasing the rotation speed of the turntable 171 and the centrifugal block 172. When the centrifugal force generated by the centrifugal block 172 exceeds the deformation limit of the elastic element 173, the centrifugal block 172 slides inside the turntable 171 and adaptively seals the groove, thereby automatically adjusting the gas flow rate and speed to avoid the effect of the electrostatic adsorption roller 15 being unable to efficiently adsorb and filter fine particulate impurities in the gas due to excessively fast airflow.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
