[0025] The movable support part 10 can adjust the dust removal position of the dust removal part 20, so that the dust removal device can adapt to a variety of mining machines.

[0026] See also Figure 1 and Figure 2The mobile support part 10 includes a top frame 110, a support leg 120 and a mobile frame 130. The support leg 120 is arranged below the top frame 110 by welding, the mobile frame 130 is located above the top frame 110, and a roller 140 rolling on the top frame 110 is installed below the mobile frame 130. A motor 150 for driving the roller 140 to rotate is installed on the mobile frame 130. The shaft end of the motor 150 is connected to the roller 140 to drive the roller 140 to rotate. The dust removal part 20 includes a dust hood 210, a fan 220 and a dust box 230. The fan 220 and the dust box 230 are respectively installed above and below the mobile frame 130, the dust hood 210 is located below the top frame 110, and an air inlet pipe 240 is connected between the back of the dust hood 210 and the air inlet port of the fan 220, and an air outlet pipe 250 is connected between the air outlet port of the fan 220 and the dust box 230.

[0027] The operation of the fan 220 generates negative pressure, and the dust generated by the operation of the mining machinery is sucked into the dust hood 210. The dust in the air finally enters the dust box 230 through the air inlet pipe 240 and the air outlet pipe 250 and is collected, thereby reducing the dust generated by the operation of the mining machinery and protecting the safety of the operator. By controlling the motor 150 to drive the roller 140 to rotate, the roller 140 rotating above the top frame 110 drives the mobile frame 130 to move, that is, drives the dust removal part 20 on the mobile frame 130 to move as a whole, so as to realize the movement and adjustment of the dust hood 210. According to different mining machinery and equipment, the position of the dust hood 210 is adaptively adjusted to improve the applicability of the device when in use.

[0028] For further information, see Figure 1 , guide rails 160 are arranged on both sides above the top frame 110, and the roller 140 is fixedly arranged above the guide rails 160. The guide rails 160 are used to improve the stability of the roller 140 when rolling. The mobile bracket part 10 also includes positioning blocks 170, and two positioning blocks 170 are respectively fixedly arranged at both ends of the guide rails 160. The positioning blocks 170 are arranged to prevent the roller 140 from falling off from the ends of the guide rails 160.

[0029] For specific settings, see Figure 2 The air inlet pipe 240 includes a connecting pipe 241, a lower bellows 242 and an upper bellows 243. The two ends of the connecting pipe 241 are respectively connected to the lower bellows 242 and one end of the upper bellows 243. The bottom end of the lower bellows 242 is connected to the back of the dust hood 210, and the top end of the upper bellows 243 is connected to the air inlet port of the fan 220. The dust removal part 20 also includes a handle 260, which is set at the back of the dust hood 210. The setting of the upper bellows 243 and the lower bellows 242 can achieve a certain degree of adjustment of the angle of the dust hood 210, that is, holding the handle 260 and turning it to adjust the dust hood 210 to accurately face the dust discharge area of ​​the mechanical equipment, thereby improving the dust removal effect.

[0030] In the above specific implementation, please refer to Figure 3 and Figure 4 The dust box 230 includes a box body 231 and a conduit 232. The bottom end of the air outlet pipe 250 is connected to the top of the box body 231, and the conduit 232 is connected to the top of the box body 231, and a filter cloth 233 is arranged on the top of the conduit 232. The dust box 230 also includes a filter plate 234, and the filter plate 234 is arranged at the bottom of the conduit 232. The dust mixed with the air enters the box body 231, and the over-pressure air is discharged through the filter plate 234 and the filter cloth 233, so that the box body 231 collects dust.

[0031] Furthermore, the dust box 230 further includes a bracket 235 , the box body 231 is fixed on the bracket 235 , and the top of the bracket 235 is fixedly arranged with the movable frame 130 . The bracket 235 is used to support the box body 231 .

[0032] It should be noted that the specific model specifications of the motor 150 and the fan 220 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail. The power supply and principle of the motor 150 and the fan 220 are clear to those skilled in the art and will not be described in detail here.

[0033] The working principle of the mining machinery dust removal device is as follows: when in use, the fan 220 generates negative pressure when the mining machinery is in operation, and the dust generated by the operation of the mining machinery is sucked into the dust hood 210. The dust in the air finally enters the dust box 230 through the air inlet pipe 240 and the air outlet pipe 250 and is collected, thereby reducing the dust generated by the operation of the mining machinery and protecting the safety of the operator. By controlling the motor 150 to drive the roller 140 to rotate, the roller 140 rotating above the top frame 110 drives the mobile frame 130 to move, that is, drives the dust removal part 20 on the mobile frame 130 to move as a whole, realizes the movement and adjustment of the dust hood 210, and according to different mining machinery and equipment, the position of the dust hood 210 is adaptively adjusted to improve the applicability of the device when in use.
