[0054] A protective ventilation assembly 6 is installed at one end of the mobile box 1. The protective ventilation assembly 6 includes a spring damper 601, a mounting plate 602, a cylinder 603, a protective plate 604, a spring telescopic column 605, a start switch 606, an insertion rod 607, a support column 608, a spring telescopic rod 609, an adjustment frame 610, a ventilation sleeve 611, a closing frame 612, and a push plate 613;

[0055] At one end of the mobile box 1 and one end of the protective box 5, a plurality of spring dampers 601 are installed by screws. At the top of the plurality of spring dampers 601 at one end, they are connected by a mounting plate 602. At one end of the bottom of the mounting plate 602, a cylinder 603 is installed by screws.

[0056] At the top of the mobile box 1, a plurality of spring telescopic rods 609 are installed by screws. The tops of several spring telescopic rods 609 are connected by an adjustment frame 610. Between one end of the adjustment frame 610 and the closing frame 314 at one end of the mobile box 1, they are connected by a ventilation sleeve 611. The ventilation sleeve 611 includes a fixed sleeve and a movable sleeve. The movable sleeve is slidably connected inside the fixed sleeve. The fixed sleeve is fixedly connected to the closing frame 314 at one end of the mobile box 1.

At the bottom of the adjustment frame 610, a closing frame 612 is installed by screws. The closing frame 612 includes an adjustment plate and two closing strips. Ventilation holes are provided in the guide frame 302 and the box cover 2 corresponding to the positions of the closing strips. The closing strips close the ventilation holes. At both ends of the adjustment frame 610, push plates 613 are installed by screws. One end of the bottom of the push plate 613 is fixedly connected to the top surface of the mounting plate 602.

[0057] Personnel can move by pushing the mobile box 1. After moving the mobile box 1 to a suitable position, turn on the dust suction fan 301 to conduct dust suction treatment inside the coal mine roadway. During the dust suction process, due to the dust blocking the light, the light receiver 310 cannot receive the signal from the light emitter 309. At this time, the water pump 311 is turned on to pump out the water at the bottom of the mobile box 1 and spray it out from the nozzle 313 to conduct dust suppression treatment on the dust sucked into the suction guide frame 302, so that the dust enters the inside of the collection box 303, and the dust is collected and processed, realizing the dust removal treatment inside the coal mine roadway and conducting dust suppression treatment on the dust, avoiding the problem that dust splashes during the dust removal process and requires secondary collection. During the dust collection process, the driving gear 308 is meshed and connected with the connecting gear 307. The driving gear 308 fixedly connected to the output shaft inside the dust suction fan 301 rotates to drive the connecting gear 307 to rotate, and then the reciprocating threaded rod 305 rotates, realizing the reciprocating movement of the two compression plates 306, compressing the dust inside the collection box 303, so that more dust can be collected inside the collection box 303, without personnel frequently cleaning the collection box 303, reducing the labor intensity of personnel, and being able to clean the top surface of the bearing filter net 304, enabling the water flow to quickly flow to the bottom end inside the mobile box 1, facilitating continuous dust suppression treatment on the dust;

[0058] During the dust removal process, the reciprocating threaded rod 305 rotates to drive the cam 401 to rotate. When the cam 401 rotates, it contacts the moving frame 403, causing the moving frame 403 to move up and down, and then realizing the movement of the cleaning rod 404. The inner wall of the collection box 303 is cleaned by the cleaning rod 404, avoiding the problem that the water-carrying dust adheres to the inner wall of the collection box 303 and affects the dust suppression of the dust. At the same time, it avoids the problem that the dust solidifies on the inner wall of the collection box 303, resulting in inconvenient cleaning. During this process, the tooth bar 405 is meshed and connected with the driving gear 406. When the tooth bar 405 reciprocates, it drives the driving gear 406 to reciprocate, and then realizes the reciprocating rotation of the rotating shaft 407. At this time, the connecting rope 408 straightens and rotates due to the centrifugal force, causing the knocking ball 409 to continuously knock on the barrier net 410 to conduct ash cleaning treatment on the barrier net 410, avoiding the problem that the dust causes the barrier net 410 to be blocked and affects the dust adsorption. And through the blocking of the barrier net 410, it can prevent the dust from directly contacting the dust suction fan 301 and causing damage to the dust suction fan 301;

[0059] When a coal mine roadway collapses, the collapse above the equipment will fall to the top of the adjustment frame 610 and press the adjustment frame 610, causing the spring telescopic rod 609 to compress. The movement of the adjustment frame 610 drives the movement of the closing frame 612 and the pushing plate 613. The movement of the closing frame 612 closes the end of the guiding frame 302, opens the guiding frame 302 and the top of the box cover 2, and realizes the ventilation treatment of the dust removal equipment from the top of the moving box 1. The movement of the pushing plate 613 drives the movement of the mounting plate 602, so that the mounting plate 602 contacts the start switch 606, and the air cylinder 603 can be started immediately to push the protection plate 604 to rotate. The end of the protection plate 604 will contact the inner wall of the roadway to support the collapse and form an effective protection space for people to hide. The collapse is buffered by the spring damper 601 to reduce the damage to the equipment caused by the collapse and extend the service life of the dust removal equipment. When people hide under the protection plate 604, the dust suction fan 301 is turned on, so that the wind passes through the bottom of the closing frame 314 and enters the top of the guiding frame 302, and then is discharged through the inside of the guiding frame 302 to form a ventilation environment to ensure the safety of people's lives.

[0060] The input ends of the dust suction fan 301, the light emitter 309, the light receiver 310, the water pump 311 and the start switch 606 are all electrically connected to the output end of the storage battery 7.

[0061] Finally, it should be noted that the above are only preferred examples of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
