There is a pulse electromagnet 11, which is connected to the control panel 5 through an internal circuit. Multiple groups of springs 12 are installed on the inner wall of the sliding groove 8. The other end of the spring 12 is fixedly connected to the side wall of the connecting ring 9. Two groups of limit grooves 13 are opened on the outer wall of the filter tube 6. The limit blocks 14 are assembled in the limit grooves 13, and the limit blocks 14 are fixedly connected to the inner wall of the circular hole. When working, the existing dust removal device needs to frequently disassemble and clean the internal filter 7 to avoid clogging in the process of cooperating with the mining drill rig for dust removal. However, the steps of disassembling the filter 7 are cumbersome, which makes it difficult to clean the filter 7. The control panel 5 is used to pass the sinusoidal current through the wire into the pulse electromagnet 11, so that the pulse electromagnet 11 is magnetized and the sinusoidal current switches between positive and negative half cycles. Whenever the sinusoidal current switches between positive and negative half cycles, the sinusoidal current disappears. The frequency of the switching between positive and negative half cycles of the sinusoidal current is very high, so the frequency of the magnetic field generated by the pulse electromagnet 11 is also very high. The magnetic force generated by the pulse electromagnet 11 is also instantaneous. The moment the pulse electromagnet 11 generates magnetic force, it attracts the iron sheet 10 to move toward the pulse electromagnet 11, and the iron sheet 10 drives the connecting ring 9 to move horizontally to the right. The connecting ring 9 drives the filter tube 6 to move horizontally to the right, and then the magnetic force disappears. Under the thrust of the spring 12, the spring 12 pushes the connecting ring 9 to move horizontally to the left, and the connecting ring 9 drives the filter tube 6 to move horizontally to the left. Since the switching frequency of the generation and disappearance of the magnetic field is extremely high, the filter tube 6 generates high-frequency vibrations, and the filter tube 6 drives the filter screen 7 thereon to generate high-frequency vibrations. The dust accumulated on the filter screen 7 is shaken off and falls into the collection box 22, thereby realizing efficient and convenient cleaning of the filter screen 7, avoiding frequent disassembly and cleaning of the filter screen 7, and being conducive to improving the convenience of cleaning the filter screen 7.

[0020] See also Figure 3-5As shown, a driving motor 15 is installed in the exhaust box 3 through the machine base, a rotor 16 is installed on the output shaft of the driving motor 15, and a fan blade 17 is installed on the rotor 16. An exhaust slot 18 is provided on the side wall of the exhaust box 3, and two sets of movable slots 19 are provided on the bottom plate of the collecting box 1. A movable block 20 is assembled in the movable slot 19, and a movable plate 21 is installed on the movable block 20. A collecting box 22 is placed on the movable plate 21, and a handle 23 is installed on the side wall of the collecting box 22. A box door 24 is rotatably installed on the side wall of the collecting box 1, a buckle 25 is installed on the outer wall of the box door 24, a card plate 26 is rotatably installed on the outer wall of the collecting box 1, and a tripod 27 is installed on the bottom side of the collecting box 1; when working, the existing dust removal device is difficult to efficiently clean a large amount of dust in the process of dust removal in conjunction with a mining drill. The dust removal effect is poor. The dust generated by the drilling rig during operation is driven by the driving motor 15, which drives the fan blades 17 to rotate at high speed. The air inside the collection box 1, the dust collection box 2 and the exhaust box 3 is discharged from the exhaust slot 18. The collection box 1, the dust collection box 2 and the exhaust box 3 are instantly vacuumed, and there is an air pressure difference with the outside world. Under the action of the pressure difference, the outside air and the dust generated by the drilling rig are sucked into the dust collection box 2 from the dust collection pipe 4, and the particulate dust in the air is intercepted by the filter 7. The clean air is discharged from the exhaust slot 18, thereby achieving dust removal of the air. The particulate dust intercepted by the filter 7 will fall down into the collection box 22 and be collected by the collection box 22. The collection box 22 has a large capacity and can collect a large amount of dust, which is beneficial to improving the dust removal effect.

[0021] Working principle: In the process of dust removal in conjunction with a mining drill, the existing dust removal device needs to frequently disassemble and clean the filter 7 to avoid clogging. However, the steps of disassembling the filter 7 are cumbersome, resulting in poor convenience in cleaning the filter 7. A sinusoidal current is passed through the wire to the pulse electromagnet 11 through the control panel 5, so that the pulse electromagnet 11 is magnetized, and the sinusoidal current switches between positive and negative half cycles. Whenever the positive and negative half cycles of the sinusoidal current are switched, the sinusoidal current disappears. The frequency of switching between the positive and negative half cycles of the sinusoidal current is very high, so the pulse electromagnet 11 The frequency of the magnetic field generated is also very high, and the magnetic force generated by the pulse electromagnet 11 is also instantaneous. The moment the pulse electromagnet 11 generates magnetic force, it attracts the iron sheet 10 to move toward the pulse electromagnet 11, and the iron sheet 10 drives the connecting ring 9 to move horizontally to the right, and the connecting ring 9 drives the filter tube 6 to move horizontally to the right. After that, the magnetic force disappears. Under the thrust of the spring 12, the spring 12 pushes the connecting ring 9 to move horizontally to the left, and the connecting ring 9 drives the filter tube 6 to move horizontally to the left. Since the switching frequency of the generation and disappearance of the magnetic field is extremely high, the filter tube 6 generates high-frequency vibration, and the filter tube 6 drives the filter mesh thereon The dust collecting box 22 is convenient for cleaning the filter 7 and avoids the need to frequently disassemble and clean the filter 7, which is beneficial to improving the convenience of cleaning the filter 7. The existing dust removal device is difficult to efficiently clean a large amount of dust in the process of cooperating with the mining drill to remove dust, resulting in poor dust removal effect. The dust generated by the drilling machine during operation is driven by the driving motor 15 to drive the fan blades 17 to rotate at high speed, and the air inside the collection box 1, the dust collection box 2 and the exhaust box 3 is discharged. The air is discharged from the exhaust groove 18, and the interior of the collection box 1, the dust collection box 2 and the exhaust box 3 are instantly vacuumed, and there is an air pressure difference with the outside world. Under the action of the pressure difference, the outside air and the dust generated by the drilling rig are sucked into the dust collection box 2 from the dust collection pipe 4, and the particulate dust in the air is intercepted by the filter 7. The clean air is discharged from the exhaust groove 18, and the dust removal of the air is realized. The particulate dust intercepted by the filter 7 will fall down into the collection box 22 and be collected by the collection box 22. The collection box 22 has a large capacity and can collect a large amount of dust, which is beneficial to improve the dust removal effect.
