The working principle is that when the shield machine excavates the tunnel, the belt frame 1 is arranged on the shield machine, used for conveying the excavated soil outwards, the excavated soil blocks fall on a conveying belt arranged at the end part of the conveying wheel 11, the conveying belt is driven to rotate on the side wall of the conveying wheel 11 along with the driving of a motor, the hardened soil blocks are conveyed outwards along with the conveying belt, when the hardened soil blocks are conveyed to the bottom end of the fixed frame 12, the larger soil blocks enter the bottom end of the fixed plate 13 and are driven by the conveying belt to rub the wire netting 14, because the soil blocks are loose and are cut and crushed into small blocks by the iron net on the iron wire net 14, the soil blocks are conveyed outwards along with other small soil blocks from the bottom end of the fixed frame 12, the machine is prevented from being damaged by falling of the large soil blocks on the other group of belt frames 1, and even the soil recovery in the later period is influenced, meanwhile, the arc-shaped net surface of the wire netting 14 is utilized to crush the large soil blocks attached to a larger area; the motor drives the conveying belt to rotate, the conveying belt drives the conveying wheel 11 to rotate, meanwhile, the connecting belt 22 on the side wall of the conveying wheel 11 rotates to drive the rotating shaft 2 to rotate, the cam 21 fixedly connected with the side wall of the rotating shaft 2 rotates to jack the conveying belt, and the large soil blocks are jacked by the cam 21 and are extruded by being attached to the bottom end of the wire netting 14, so that the large soil blocks are crushed rapidly, the situation that the large soil blocks are smashed on the belt frame 1 and impact on soil recovery due to the fact that the large soil blocks are large is avoided; when the large soil blocks are conveyed to the bottom end of the fixed shaft 3, the large soil blocks are in friction with the rolling roller 31 along with the driving of the conveying belt, the large soil blocks can be rolled by the rolling roller 31 if being large, the large soil blocks are decomposed by matching with the barbed heads 32, the decomposed soil blocks are jacked up by the cam 21 and are in friction crushing by being attached to the bottom end of the wire netting 14, and the large soil blocks are prevented from falling to damage the belt frame 1 and even influence the subsequent recovery of soil; water is filled into the water tank 4, the water in the water tank 4 is pumped by the water pump 41 and is conveyed to a plurality of groups of atomizing nozzles 43 through a first conveying pipe 42 for spraying, water mist sprayed by the atomizing nozzles 43 is sprayed on the surface of soil blocks on a conveying belt, the soil blocks are soaked and softened by the water mist, and are ground by the grinding roller 31 and rubbed and crushed by the wire netting 14, so that the grinding effect on the soil blocks is enhanced, meanwhile, dust generated when the soil blocks are ground by the water mist is sprayed, the dust falling effect is achieved, and the conveying belt is repeatedly jacked up by the cam 21 along with the rotation of the conveying wheel 11, so that the soil blocks are prevented from being adhered to the conveying belt; when water is poured into the water tank 4, the sealing plug 53 is screwed by the screw threads to open the water tank 4, a water pipe penetrates into the water tank 4 to be added with water, the water flows into the filter screen plate 51 on the side wall of the filter tank 5 to achieve the effect of filtering impurities, the atomizing nozzle 43 is prevented from being blocked to influence the sprayed water mist to soften soil blocks, the flowing water impacts the end part of the knocking plate 52, the knocking plate 52 rotates on the side wall of the filter tank 5 and knocks the side wall of the filter tank 5 to drive the filter screen plate 51 to vibrate, and the end part of the filter screen plate 51 is prevented from being blocked by impurities to influence the water pouring; the water pump 41 pumps water and is conveyed from the first conveying pipe 42, part of the water flows into the second conveying pipe 6, the water in the second conveying pipe 6 accumulates and presses the punching plate 61 to slide downwards, the spring 62 is contracted and stressed, the punching plate 61 drives the rotating plate 63 to rotate on the inner side wall of the fixed frame 12, the knocking block 64 is lifted up, when the water flows through, the knocking block 64 knocks the side wall of the fixed plate 13 to vibrate, the soil on the wire netting 14 is driven to fall off, the soil block crushing effect is prevented from being influenced, and meanwhile, when the water flows through too much, the water can flow back to the inside of the water tank 4 from the water guide groove formed in the fixed frame 12, the effect of valve release is achieved, and along with the change of the water flow speed, the knocking block 64 is driven to knock the side wall of the fixed plate 13 repeatedly to vibrate; the rotating plate 63 is extruded and rotated by the stamping plate 61 to drive the knocking block 64 to be lifted, the elastic pull rope 7 is pulled to extend, when the water flow is too small, the elastic pull rope 7 quickly pulls the rotating plate 63 to reset, the stamping plate 61 is jacked by the aid of the spring 62, the knocking block 64 also quickly knocks the end portion of the fixed plate 13, the friction pad 71 prevents the knocking block 64 from directly impacting the end portion of the fixed plate 13 to cause serious abrasion for a long time, and the vibration effect on the side wall of the wire mesh 14 is enhanced; the fixing plate 13 vibrates to drive the wire netting 14 to vibrate, the multiple groups of lifting ropes vibrate and swing along with the vibration of the magnetic balls 8, the multiple groups of magnetic balls 8 impact the side wall of the elastic sheet 81, the elastic force of the elastic sheet 81 is utilized to drive the multiple groups of magnetic balls 8 to impact and swing, and the wire netting 14 is driven to vibrate at the same time, so that the effect of enhancing the vibration of the wire netting 14 is achieved, and the influence on the crushing effect of soil blocks due to the adhesion of soil to the side wall of the wire netting 14 is avoided; the rotor plate 63 rotates and drives the piece 64 perk of strikeing, strikes when the piece 64 of strikeing and strikes at fixed plate 13 tip, and cooperation magnetic ball 9 and 8 magnetism repellents of multiunit magnetic ball, and the power of repellence is less, drives the lifting rope on the magnetic ball 8 and sways, and magnetic ball 8 strikes on the shell fragment 81 and produces vibrations repeatedly to wire netting 14, plays reinforcing vibrations and to the clear effect of wire netting 14 lateral wall soil.
