When the pressure sensor 6 detects that the pressure value of the sand and gravel on the inner wall of the sand shoveling bucket 2 reaches the set pressure value, it sends a signal to the controller 8. After receiving the signal, the controller 8 sends a closing signal to the second drive device 15, and at the same time sends an operation signal to the first drive device 5. After receiving the signal, the first drive device 5 drives the sand shoveling bucket 2 to flip and input the sand and gravel into the storage bag. When the pressure sensor 6 detects that the pressure is 0, it sends a signal to the controller 8. After receiving the signal, the controller 8 sends a signal to the first drive device 5. The first drive device 5 resets after receiving the signal. When the position sensor 17 detects that the distance between the box and the sand shoveling bucket reaches the set value, it sends a stop signal to the first drive device 5, and at the same time sends an operation signal to the second drive device 15. When the weighing device 7 detects that the mass of sand and gravel in the storage bag reaches the set value, it sends a signal to the controller 8.
