Specific implementation method:

[0030] The present invention is further described below with reference to specific embodiments. Figure 1 —11:

[0031] The utility model provides a soil loading vehicle, which includes a soil feeding mechanism 1, a soil storage box 2 located above the soil feeding mechanism 1, and a traveling mechanism 3 that drives the soil feeding mechanism 1 to move. The soil feeding mechanism 1 is a conveyor belt transmission mechanism. A guide hopper 4 is provided at the output end of the soil feeding mechanism 1. The axis of the outlet end of the guide hopper 4 is arranged in the vertical direction. A soil throwing nozzle 5 is rotatably provided at the outlet end of the guide hopper 4. The outlet of the soil throwing nozzle 5 is located on one side of the axis of the outlet end of the guide hopper 4. The soil throwing nozzle 5 can be rotated on the guide hopper 4 to adjust the soil throwing position, that is, the outlet of the soil throwing nozzle 5 rotates 360 degrees around the axis of the outlet end of the guide hopper 4. A soil fullness sensor 6 is provided on the soil throwing nozzle 5. The soil fullness sensor 6 can realize that after the soil pile reaches a certain height, the soil loading vehicle can automatically retreat or advance to carry out the next soil throwing.

[0032] The outlet of the soil-throwing nozzle 5 of the utility model can rotate 360 ​​degrees around the axis of the outlet end of the guide hopper 4, so as to adjust the soil-throwing position by 360 degrees and realize soil-throwing at different positions.

[0033] Furthermore, the upper end of the soil-throwing spout 5 is mounted on the outlet end of the guide hopper 4, an upper convex edge 7 is radially extended from the outer side wall of the upper end of the soil-throwing spout 5, and a limiting ring 8 is mounted on the upper end of the soil-throwing spout 5, the limiting ring 8 includes a lower convex edge 9, the limiting ring 6 is fixedly connected to the guide hopper 4, and the upper convex edge 7 is limited on the lower convex edge 9.

[0034] In addition, the utility model further forms a step surface 10 on the inner wall of the upper end of the soil throwing nozzle 5 , and the lower end surface of the guide hopper 4 is limited to the step surface 10 .

[0035] The upper and lower limits of the soil-throwing spout 5 can be achieved by the upper convex edge 7 , the lower convex edge 9 and the step surface 10 .

[0036] It should be noted that the rotation of the soil injection nozzle 5 of the present invention is achieved manually. After rotation, it needs to be positioned. The present invention has a plurality of spherical grooves circumferentially arranged on the upper convex edge 7, and a threaded hole is radially arranged on the upper edge of the limiting ring 6. The adjusting screw 11 is screwed into the threaded hole, and a spring and a limiting bead 12 are arranged between the adjusting screw 11 and the spherical groove. Generally speaking, the limiting bead 12 is a steel ball. The spherical grooves are evenly distributed circumferentially, and the specific number of spherical grooves is set according to actual needs. When rotating, the limiting bead 12 comes out of the spherical groove, compresses the spring, and after rotating the corresponding angle, the limiting bead 12 enters the corresponding spherical groove for positioning.

[0037] The outer side wall of the guide hopper 4 of the utility model is provided with a plurality of mounting columns 13 arranged in the vertical direction, and threaded holes are provided on the bottom surfaces of the mounting columns 13 facing upward. The limiting ring 6 is provided with through holes 14 whose positions and numbers correspond to the mounting columns 13 one by one. Screws pass through the through holes 14 and are screwed into the threaded holes of the mounting columns 13 to achieve a fixed connection between the limiting ring 6 and the guide hopper 4.

[0038] Furthermore, the soil full sensor 6 is a through-beam photoelectric sensor, including a transmitting end 15 and a receiving end 16. The transmitting end 15 is arranged at the upper end of the outlet of the soil injection nozzle 5, and the receiving end 16 is located on one side of the transmitting end, or the positions of the transmitting end 15 and the receiving end 16 are swapped with each other.

[0039] When the soil is pushed to the height of the outlet of the soil-feeding nozzle 5, part of the soil will be squeezed and block the transmitting end 15 and the receiving end 16. At this time, the soil full sensor 6 sends the signal to the controller, and the controller controls the soil-feeding mechanism 1 to stop feeding the soil, and controls the walking mechanism 3 to move the soil vehicle backward a corresponding distance, and starts the soil-feeding mechanism 1 to feed the soil again, and feeds the soil from the soil-feeding nozzle 5, and this cycle continues.

[0040] Of course, the soil full sensor 6 of the present invention can also be a micro switch. The micro switch is set at the bottom of the soil injection nozzle 5. When the soil is injected to a certain height, the top of the soil pile triggers the micro switch, and then the controller sequentially controls the soil feeding mechanism 1 and the walking mechanism 3 to move.

[0041] The lower end of the soil storage box 2 of the present invention is open, and the opening is located above the soil feeding mechanism 1. A vibrator is provided in the inner cavity of the soil storage box 2 near the opening. The vibrator includes a shell and a vibration motor 17 arranged in the shell. The shell includes a first soil guide plate 18 and a second soil guide plate 19 for guiding the soil to the soil feeding mechanism 1. The shell is fixed to the inner cavity of the soil storage box 2 through a support rod 20.

[0042] The vibrator supports the weight of the soil, preventing the entire weight of the soil in the soil storage box 2 from acting on the soil delivery mechanism 1. The soil is introduced into the soil delivery mechanism 1 via the first and second soil guide plates 18 and 19. However, if soil accumulates on the vibrator or the amount introduced into the soil delivery mechanism 1 is too small, a weight sensor or other sensing structure will send a signal to the controller, which will control the vibration motor 17 to activate the soil, causing the soil to fall onto the soil delivery mechanism 1.

[0043] In addition, in order to facilitate manual movement, the present invention provides a handle 21 on the guide hopper 2 for easy pushing and pulling.

[0044] It should be noted that the traveling mechanism 3 of the present invention includes a frame 22, and the soil feeding mechanism 1 is installed on the frame 22. The front traveling wheel assembly 23 and the rear traveling wheel assembly 24 are arranged on the frame 22, and the front traveling wheel assembly 23 and the rear traveling wheel assembly 24 are respectively driven to rotate by corresponding motors, forming a four-wheel drive structure. The front traveling wheel assembly 23 and the rear traveling wheel assembly 24 run on a track. A wheel axle 25 is provided on the frame 22 between the front traveling wheel assembly 23 and the rear traveling wheel assembly 24. The two ends of the wheel axle 25 are connected to the wheels (not shown in the figure) through swing arms. A driving arm 26 is provided on the wheel axle 25, and one end of the driving arm 26 is connected to a push rod, which is fixed to the frame 22. The telescopic arm of the push rod 22 drives the driving arm 26 to move and then drives the wheel axle 25 to rotate, and the swing arm connected to the wheel axle 25 moves accordingly to drive the wheel to rise and fall.

[0045] When the wheels are in the raised state, the wheels are not in contact with the ground, and the walking of the utility model is achieved by the front running wheel assembly 23 and the rear running wheel assembly 24. When the utility model tilts to one side, the wheels in the raised state can abut against the ground, play a supporting role, and prevent rollover.

[0046] When the wheels are in the lowered state, the wheels are in contact with the ground and the vehicle is moved by the wheels.

[0047] The above embodiment is only one of the preferred embodiments of the present invention and is not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes made based on the shape, structure, and principle of the present invention should be included in the scope of protection of the present invention.
