When the up-and-down position of the crushing box 42 is adjusted according to mining requirements, the motor 25 is started first, the motor 25 rotates to drive the rotation shaft four 26 to rotate, the rotation shaft four 26 rotates to drive the rotation shaft seven 31 to rotate, the rotation shaft seven 31 rotates to drive the rotation of the spline gear 36, the rotation of the spline gear 36 drives the rotation shaft six 32, the rotation of the gear six 32 drives the rotation shaft six 61 to rotate, the rotation shaft six 61 rotates to drive the rotation shaft intermediate belt wheel 63 to rotate, the rotation shaft two 67 rotates to drive the rotation shaft belt wheel 68 to rotate, the rotation shaft 68 rotates to drive the rotation shaft five 69 to rotate, the rotation shaft five 69 rotates to drive the rotation shaft four 70 to rotate, the rack push rod 55 to slide close to the rotation shaft six 61 side, the adjusting belt wheel 60 and the slide block two 57 to slide close to the rotation shaft six, the fifth gear 66 rotates and slides the third counter slide block 65 upwards, so that the first slide block 41 is driven to slide upwards along the first slide cavity 23, the first rotating shaft 40 and the crushing box 42 are driven to move and adjust upwards, the second pulley cavity 62 is always kept in a tight state, and the transmission is not influenced while the adjustment is carried out.

When the coal mine wall is mined, firstly, the first electromagnet 34 and the second electromagnet 38 are powered off, so that the spline gear 36 slides leftwards under the action of the tension of the third expansion spring 35, the spline gear 36 is disengaged from the seventh gear 31 and the sixth gear 32, then the motor 25 is started, the motor 25 is started to drive the fourth rotating shaft 26 to rotate, the fourth rotating shaft 26 rotates to drive the lower belt wheel 43 to rotate, the lower belt wheel 43 rotates to drive the first transmission belt 29 to rotate, the first transmission belt 29 rotates to drive the upper belt wheel 39 to rotate, the upper belt wheel 39 rotates to drive the first rotating shaft 40 to rotate, the first rotating shaft 40 rotates to drive the rotating plate 74 to rotate, the rotating plate 74 rotates to drive the transmission ring 46 to rotate, the transmission ring 46 rotates to drive the second rotating shaft 48 to rotate, meanwhile, the first rotating shaft 40 rotates to drive the first gear 52 to rotate, the first gear 52 rotates to drive the third gear 50 to rotate, and the, the crushing drill bits 44 arranged in an array are driven to rotate, so that the crushing box 42 is driven to move by driving the vehicle body 10 to move integrally, and the crushing drill bits 44 are used for performing wall breaking mining on a coal mine to be mined; meanwhile, the rotating shaft IV 26 rotates to drive the bevel gear I27 to rotate, the bevel gear I27 rotates to drive the bevel gear II 30 to rotate, the bevel gear II 30 rotates to drive the rotating shaft IV 19 to rotate, the rotating shaft IV 19 rotates to drive the hinge rod 17 to rotate, so that the hinge rod 17 is driven to slide left and right in the pump cavity 13 to suck air, external coal dust is sucked in, then the external coal dust enters the guide pipe IV 15, enters the guide pipe IV 12 through the pump cavity 13, and finally enters the collection box 11 to recycle the coal dust, so that the air dust density in a working environment is protected to the maximum extent, and the harm to a human body is reduced.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and scope of the present invention are intended to be included therein.
