Further, the cover is equipped with second thrust spring 54 on the vertical square pole 53 of second, second thrust spring 54 is located and connects between the backplate 51 on vertical fixed cover 14 and the second, under the thrust effect of second thrust spring 54, make screw axis mounting 5 and spiral pivot pole 6 have decurrent effect reason extrusion subaerial, be equipped with spiral pivot pole 6 between two pivot fixed plates 52, be equipped with spiral pivot piece 61 on the face of cylinder of spiral pivot pole 6, spiral pivot piece 61 is with middle demarcation, the spiral opposite direction of demarcation both sides, the equal coaxial fixed band pulley 62 that is equipped with in both ends of spiral pivot pole 6, be convenient for realize pushing garrulous cement to both sides through the rotation of spiral pivot piece 61.

In this embodiment, the caterpillar tracks are connected between the belt wheel 62 and the central transmission wheel 43 and between the central transmission wheels 43, so as to facilitate the transmission between the structures.

The working principle of the invention is as follows: the fixing plate at the front side of the frame 1 is fixed on the tail of the motor vehicle through bolts, during the running process of the motor vehicle, the gear motor 25 is started, the output shaft of the gear motor 25 rotates to drive the gear 241 to rotate, the gear 241 is meshed with the large gear 24 to drive the rotating shaft 21 and the absent gear 22 to rotate, so that different absent gears 22 rotate along with the rotating shaft, the hitting prong 26, the lower slide bar 27, the upper slide bar 28 and the rack bar 29 are driven by the rotating absent gear 22 to move upwards, the accelerating thrust spring 281 is compressed, when the toothless area 221 on the absent gear 22 is mutually jointed with the rack bar meshing teeth 291, the teeth on the absent gear 22 are not mutually meshed with the rack bar meshing 291, the hitting prong 26, the lower slide bar 27, the upper slide bar 28 and the rack bar 29 move downwards rapidly under the action of the self weight and the thrust of the accelerating thrust spring 281, the striking tips 26 strike the ground, so that the ground is broken, the positions of the toothless areas 221 on different segmental gears 22 are different, so that the time for attaching different toothless areas 221 to the rack bar engaging teeth 291 corresponding to the positions is different, the time for the different striking tips 26 to land is different, meanwhile, the first belt wheel 23 rotates along with the rotating shaft 21, the central driving wheel 43 rotates through crawler transmission, the rotation of the central driving wheel 43 drives the central gear 432 to rotate, the central gear 432 is meshed with the plurality of turnover gears 42, the turnover gears 42 are meshed with the internal gear 311 at the same time, the revolution and the rotation among the plurality of turnover gears 42 are realized, so that the revolution and the rotation of the breaking rotating shaft 41 are driven, the breaking pieces 411 on the adjacent breaking rotating shafts 41 move in a staggered manner, so that the breaking pieces 411 scrape broken cement blocks on the ground, the broken cement blocks enter between the mutually staggered crushing pieces 411, the broken cement blocks are further crushed, when the ground broken cement is scraped by the crushing rotating shaft 41 and the crushing pieces 411, the crushing rotating shaft fixing part 3 and the planetary stirring device 4 slightly float up and down under the elastic action of the first thrust spring 34, and the first vertical square rod 33 slides up and down in the vertical fixing sleeve 14 corresponding to the position;

in addition, the central driving wheel 43 transmits kinetic energy to the belt wheel 62 through the caterpillar track, so that the belt wheel 62 rotates, the spiral rotating shaft rod 6 pushes crushed cement to two sides because the spiral directions of the two ends of the spiral rotating shaft piece 61 are opposite, the cleaning is convenient, and the spiral rotating shaft rod 6 floats up and down under the thrust action of the second thrust spring 54 so as to avoid a hard cement bulge; it is worth noting that the floating distance between the planetary stirring device 4 and the helical rotating shaft 6 is so small as not to cause the slipping of the caterpillar.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
