[0025] The four moving groups 6 are fixed by four fixed cylinders 22, the crushing group 4 is fixed by the rotating cylinder 23 and the fixed block 25, and the cooling group 5 is fixedly installed on the upper end of the bottom plate 21, so as to achieve the purpose of fixing other components.

[0026] In order to achieve the purpose of breaking the road and adjusting the height of the cutter head 44, as Figure 3As shown, the crushing group 4 includes two telescopic rods 41, the upper ends of the two telescopic rods 41 are fixedly connected to the lower ends of the two fixed blocks 25 respectively, the opposite surfaces of the two telescopic rods 41 are commonly fixedly connected to a motor 42, the middle part of the upper end of the motor 42 is fixedly connected to a rotating block 45, the inner cavity of the rotating block 45 is rotatably connected to a threaded rod 46, the outer surface of the threaded rod 46 is meshedly connected to the inner cavity of a threaded groove opened in the middle part of the upper end of the rotating cylinder 23, and the output end of the motor 42 is fixedly connected to a cutter disc 44.

[0028] Because the rotating cylinder 23 is fixed and cooperates with the fixed block 25, the threaded rod 46 is rotated to cooperate with the rotating block 45, and the threaded rod 46 rotates upward or downward to drive the telescopic rod 41 to contract or stretch. At the same time, the rotating block 45 drives the motor 42 and the cutter disc 44 to move upward or downward. When it moves to a suitable position, the motor 42 can be started to break the ground through the cutter disc 44, thereby achieving the purpose of breaking the road and adjusting the height of the cutter disc 44.
