[0035] Specifically, in use, the hopper is located above the end of frame 1 close to rear wheel group 2, and the frame 1 is controlled to rotate around the hinge point on one side, so that the discharge port of frame 1 is located at the stockyard position;

[0036] When the device is moved into a warehouse or a culvert or other related facilities with an opening, by controlling the rotation of the frame 1 around the hinge point on the side of the rear wheel set 2, the angle formed by the frame 1 and the supporting surface 10 is minimized, so that the height of the entire device is minimized, which can effectively pass through the opening; of course, the height of the entire device can also be adjusted to be the lowest during movement, so that the center of gravity of the entire device is lower and the movement is more convenient;

[0037] In some possible embodiments, in order to effectively adjust the distance and position between the front wheel set 3 and the bottom of the frame 1 through the pitch driving mechanism 4;

[0038] The pitch driving mechanism 4 comprises a transmission bracket 41 hingedly connected with the front wheel set 3 and installed at the bottom of the frame 1, and a pitch driving device 42 installed at the bottom of the frame 1 and in transmission cooperation with the transmission bracket 41.

[0039] The transmission bracket 41 comprises a hinge arm 412 hingedly connected with the front wheel set 3 at one end and with the bottom of the frame 1 at the other end, and a sliding arm 411 slidably connected with the bottom of the frame 1 at one end and hingedly connected with the front wheel set 3 at the other end; the sliding arm 411 is slidably connected with the frame 1 in the axial direction of the frame 1.

[0040] The hinge arm 412 is arranged between the rear wheel set 2 and the front wheel set 3, and is hingedly connected with the hinge seat arranged at the bottom of the frame 1 at one end and with the front wheel set 3 at the other end.

[0041] The sliding arm 411 is arranged on the side of the hinge arm 412 away from the rear wheel set 2, and is slidably connected with the bottom of the frame 1 at one end and hingedly connected with the front wheel set 3 at the other end.

[0042] The pitch driving device 42 is in transmission cooperation with the sliding arm 411 and the hinge arm 412, and according to the use requirement, the sliding of the sliding arm 411 at the bottom of the frame 1 is controlled, so as to adjust the angle A formed between the hinge arm 412 and the sliding arm 411, and further change the relative position between the front wheel set 3 and the bottom of the frame 1, so that the frame 1 rotates around the hinge point of the rear wheel set 2, and the angle formed by the frame 1 and the supporting surface 10 is changed.

[0043] When the device passes through a door or a culvert, the frame 1 will be in an initial state, at which time the height of the entire device is minimized and the center of gravity is the lowest;

[0044] When in use, according to the distance between the hopper and the stockyard, the angle formed by the vehicle frame 1 and the supporting surface 10 is adjusted, so that the discharge port of the vehicle frame can effectively deliver the material to the stockyard; specifically, when the distance between the hopper and the stockyard is less than the distance when the vehicle frame 1 is in the initial state for delivery, at this time the sliding arm 411 is controlled to slide towards the side close to the hinged arm 412, the angle formed by the sliding arm 411 and the hinged arm 412 is reduced, the discharge port of the vehicle frame 1 is lifted by counterclockwise rotation around the hinge point of the vehicle frame 1 and the rear wheel set 2 to meet the distance between the hopper and the stockyard, so that the material can be delivered to the designated position.

[0046] Specifically, when the sliding arm 411 abuts against the limiting block 12 close to the hinged arm 412, the angle A formed between the hinged arm 412 and the sliding arm 411 is the smallest, that is, the angle A is the smallest, at this time the distance between the vehicle frame 1 and the rear wheel set 2 is the farthest, and the angle B formed by the vehicle frame 1 and the supporting surface 10 is the largest, that is, the angle B is the largest; on the contrary, when the sliding arm 411 abuts against the limiting block 12 away from the hinged arm 412, the angle A formed between the hinged arm 412 and the sliding arm 411 is the largest, at this time the distance between the vehicle frame 1 and the rear wheel set 2 is the closest, the angle B formed by the vehicle frame 1 and the supporting surface 10 is the smallest, and the overall height is the smallest, at this time the vehicle frame 1 is in the initial state.
