[0033] The discharge hopper 2 is installed on the vehicle frame 1, and the discharge mechanism 3 enables the discharge hopper 2 to rotate around its hinge point with the vehicle frame 1, so as to perform the discharging operation of the materials in the discharge hopper 2; the handle mechanism 4 is slidably matched with the vehicle frame 1 along the Z-axis direction. Before the construction personnel move the vehicle frame 1, the height position of the handle mechanism 4 can be adjusted according to the personal height, so as to facilitate the construction personnel to move the entire device and the materials.

[0034] In some possible implementation manners, in order to effectively control the discharge hopper 2 to act around its hinge point with the vehicle frame 1 through the discharge mechanism 3, so as to realize loading or unloading;

[0040] The guide groove is slidably matched with the slider 32 , and the guide groove can effectively limit the rotation of the slider 32 , so that the slider 32 can only make a linear motion on the lead screw 31 along the length direction of the lead screw 31 without rotating.

[0041] In some possible implementations, in order to effectively enable the handle mechanism 4 to adapt to the operation requirements of different construction workers, it is prevented that the handle mechanism 4 is too high or too low to affect the construction workers in pushing the entire frame 1 to move, making transportation more convenient and efficient;

[0042] The handle mechanism 4 is arranged on the side of the vehicle frame 1 away from the hinge point between the vehicle frame 1 and the discharging hopper 2; the handle mechanism 4 includes two groups of guide rods 41 arranged along the Z-axis direction, and a handle assembly 42 arranged between the two groups of guide rods 41 and slidably matched with the guide rods 41; on the side where the two groups of guide rods 41 are close to each other, there is a guide groove with a U-shaped cross-section; the two groups of guide rods 41 are installed on the vehicle frame 1.

[0046] During transportation, the construction personnel slide the sliding plate 421 vertically according to personal needs, and then use the locking mechanism 43 to lock the sliding plate 421 and the guide rod 41; so that the vehicle handle 422 moves to the height position that meets its own needs, and then hold the vehicle handle 422 to realize the transportation of materials.

[0047] In some possible implementation manners, in order to effectively realize the locking of the sliding plate 421 and the guide rod 41 through the locking mechanism 43.

[0048] The locking mechanism 43 includes two groups of clamping members 431 arranged along the Y-axis direction and elastically connected to the sliding plate 421 respectively, a locking member 432 installed on the clamping member 431 and used to control the movement of the clamping member 431 along the Y-axis direction, and clamping holes 411 arranged on the two guide rods 41 respectively and inserted and matched with the clamping member 431; the locking member 432 is arranged between the two groups of clamping members 431.
