[0010] Furthermore, an electric shield is provided between the two guide rails. The electric shield includes a wedge-shaped end and a telescopic end. The wedge-shaped end of the electric shield is in contact with the limiting wheel.

[0011] Furthermore, the telescopic end of the electric shield is provided with a displacement sensor, the moving unit of the displacement sensor is fixedly mounted on the moving unit of the telescopic end, and the fixed unit of the displacement sensor is fixedly mounted on the fixed unit of the telescopic end.

[0012] The beneficial effects of the present invention are:

[0013] 1. This automated belt conveyor unloading vehicle uses a power wheel to drive the frame and hopper to reciprocate along the guide rails. Pre-set limiters are installed at corresponding positions in the silo and on the frame. When the two limiters are in the same position, the hopper and the silo correspond, and the corresponding chute and baffle can be opened to discharge the material. Angle sensor 1 detects the rotation angle of the chute to determine the opening angle of the chute, and angle sensor 2 detects the rotation angle of the baffle to determine the opening angle of the baffle. This section is the discharge detection section, equipped with a blockage detection unit to detect whether the hopper is blocked, and a positioner to simultaneously detect whether the frame is located at the designated silo. This section is the pre-discharge detection section, and if an abnormality occurs in the pre-discharge detection section, the corresponding chute and baffle are closed. This enables automated unloading and prevents material leakage.

[0014] 2. The automatic belt conveyor unloading vehicle is fixedly equipped with a power wheel and a limit wheel rotatably connected to the guide rail through a set frame. The blocking end of the limiter is fixedly installed on the frame. The limiter has two blocking ends, and the two blocking ends are aligned with the power wheel and the limit wheel respectively. When the first blocking end is blocked by the fixed unit of the limiter, the power source driving the power wheel reduces the conveying power. When the second blocking end is blocked by the fixed unit of the limiter, the power wheel stops working. Through such a setting, it can be avoided that the frame is unable to stop in time due to the large inertia during the stopping process, which leads to the inability to align.

[0022] The chute 5 includes a fixed part 501 fixedly mounted on the outside of the chute hopper 3, and the outer side of the fixed part 501 is rotatably connected to the rotating part 502, the rotating part 502 and the traction mechanism 6, the traction mechanism 6 includes a motor 601, the output end of the motor 601 is fixedly mounted with a traction wheel 602, the outer surface of the traction wheel 602 is fixedly wrapped with a traction rope 603, the traction rope 603 is fixedly connected to the rotating part 502, and the winding and loosening of the traction rope 603 can drive the rotating part 502 to swing, thereby realizing the rotation of the chute 5.

[0023] The frame 2 is respectively fixedly mounted with a power wheel 201 and a limiting wheel 202 which are rotatably connected to the guide rail 1. The blocking end of the limiter 14 is fixedly mounted above the frame 2. There are two blocking ends of the limiter 14, and the two blocking ends are aligned with the power wheel 201 and the limiting wheel 202 respectively. When the first blocking end is blocked by the fixed unit of the limiter 14, the power source driving the power wheel 201 reduces the transmission power. When the second blocking end is blocked by the fixed unit of the limiter 14, the power wheel 201 stops working.
