A discharge door 6 is installed at one end of the hopper 2, and an opening and closing hydraulic cylinder 7 is connected between the middle two sides of the discharge door 6 and the two sides of the hopper 2. The extension and contraction of the opening and closing hydraulic cylinder 7 controls the opening and closing of the discharge door 6, and the discharge door 6 opens when the hopper 2 is tilted to discharge.

[0016] The lower side of the walking frame 3 is hingedly installed with multiple groups of V-shaped support seats 14, and the two ends of the lower part of the support seat 14 are respectively installed with road wheels 4. The top of the support seat 14 is provided with a through shaft 15, and the middle section of the shaft 15 is fixedly installed with the walking frame 3. The two sides of the support seat 14 are respectively fixedly installed with sleeves 17, and the sleeve 17 is concentrically sleeved on the end of the shaft 15. A torsion spring 16 is connected between the end of the shaft 15 and the sleeve 17. The support seat 14 rotates relative to the shaft 15 to adapt to the uneven ground and reduce the impact caused by the uneven ground. The torsion spring 16 is used to reset the support seat 14 after swinging, and the spiral directions of the torsion springs 16 at both ends are opposite. Two motors are provided and are respectively installed on the symmetrical sides of the base 1. The output shaft of the motor is fixedly installed with a driving wheel 8, and the driving wheel 8 is meshed with the crawler 5. The motor drives the driving wheel 8 to operate, and the driving wheel 8 drives the crawler 5 to operate to achieve walking.
