[0044] like Figure 6The main rod 8 is fixedly connected to the front and rear exteriors of a main gear 21, which is meshed with a track 22 on the exterior. This meshing connection between the main gear 21 and the track 22 allows the entire device to travel on various terrains while maintaining stability.

[0047] Working steps

[0048] Step 1: When in use, by starting the hydraulic cylinder 4 to reciprocate and extend, the extrusion plate 6 can be driven to rotate with the roller 5 as the center, and the top of the extrusion plate 6 contacts the crushing plate 3. At this time, the material to be crushed is introduced through the hopper 2, and the extrusion plate 6 and the crushing plate 3 can crush the material through the relatively protruding grinding bars.

[0049] Step 2: During the start-up of the crusher, the user can start the motor 12, and let the motor 12 drive the belt 20 to pull the main rod 8 through the support shaft 14, the auxiliary disk 15, and the turntable 13, so that the main gears 21 at both ends of the main rod 8 engage with the teeth on the inner side of the crawler 22, and cooperate with the slave rod 23 and the slave gear 24, so that the crawler 22 can drive the entire device to move. And during the movement of the device, the air pump 16 can be turned on to inflate the support shaft 14, allowing the air pressure to squeeze the piston rod 18 through the sealing cylinder 17, so that the main rod 8 pushes the grinding block 19 to expand, changing the inner diameter of the grinding block 19, so that the top part of the rotating belt 20 contacts the grinding block 19 with a larger area, and the main rod 8 drives the main gear 21 through the connection of the belt 20 to change the speed steplessly, so that the user can accurately control the walking speed according to needs.

[0050] During the movement of the device, the main rod 8 and the ring block 25 mounted on the outside of the slave rod 23 pull the movable cylinder 26, so that the crusher drives the movable cylinder 26 through the limit block 28 to pressurize the limit block 28 to slide on the outside of the guide rod 29, and drives the auxiliary gear 31 to slide on the inside of the crawler 22, and then through the elastic force of the strong spring 27 between the movable cylinder 26 and the limit block 28, drives the limit block 28 and the guide rod 29 to reset, thereby reducing the vibration of the crusher during movement and effectively reducing the vibration generated during walking.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
