DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-3, the present utility model provides a technical solution: a coal shed discharging trolley device, which includes a belt conveyor 2. A belt conveyor discharging trolley 1 is movably arranged on the top of the belt conveyor 2. A discharging chute 5 for discharging materials is arranged at the end of the belt conveyor discharging trolley 1. Cameras 7 and radar level gauges 6 are respectively installed outside the discharging chute 5 at the bottom end of the belt conveyor discharging trolley 1. Position positioning code devices 8 are equidistantly installed on the side wall of the belt conveyor 2. Wireless communication base stations 9 are installed at both the end of the belt conveyor 2 and inside the belt conveyor discharging trolley 1.

[0019] It should be noted that when the present utility model operates, coal falls on the belt surface of the belt conveyor 2 and is transported to the head through the belt conveyor discharging trolley 1, and falls into the coal shed through the discharging chute 5 to form a stockpile 3. As the stockpile 3 continuously increases in height, the height of the stockpile 3 can be accurately measured by the radar level gauge 6 and the camera 7 installed on the belt conveyor discharging trolley 1. When the stockpile 3 reaches the set value, the DCS program will start the movement of the discharging trolley traveling device 4. The traveling distance can be set by itself according to the position positioning code device 8 or can be set as a fixed distance according to the working conditions. After the belt conveyor discharging trolley 1 moves, the height of the material directly below it decreases, and the stockpile 3 can continue to be discharged. When the material reaches the set height after being stored for a period of time, the belt conveyor discharging trolley 1 will continue to move. Thus, the automatic discharging operation of the belt conveyor is realized cyclically. The height of the stockpile 3 is collected by the radar level gauge 6 and the camera 7 and transmitted to the intelligent control base station DCS control system, and the equipment performs automatic operations according to the programming; at the same time, the measured value will be transmitted to the control system in the factory central control room through the wireless communication device, and the staff can remotely control the traveling direction and distance of the belt conveyor discharging trolley 1, and can switch among the three modes of remote control, automatic control, and local control at any time.

[0020] A yard is arranged below the belt conveyor 2, and the materials output by the discharging chute 5 form a stockpile 3.

[0021] It should be noted that a yard is arranged below the belt conveyor 2, and the materials fall into the coal shed through the discharging chute 5 to form a stockpile 3. As the stockpile 3 continuously increases in height, the height of the stockpile 3 can be accurately measured by the radar level gauge 6 and the camera 7 installed on the belt conveyor discharging trolley 1. When the stockpile 3 reaches the set value, the DCS program will start the movement of the discharging trolley traveling device 4. The traveling distance can be set by itself according to the position positioning code device 8 or can be set as a fixed distance according to the working conditions. After the belt conveyor discharging trolley 1 moves, the height of the material directly below it decreases, and the stockpile 3 can continue to be discharged. When the material reaches the set height after being stored for a period of time, the belt conveyor discharging trolley 1 will continue to move. Thus, the automatic discharging operation of the belt conveyor is realized cyclically, thereby realizing automatic discharging and saving labor costs.

[0022] Discharging trolley traveling devices 4 are symmetrically installed at the bottom of the belt conveyor discharging trolley 1.

[0023] It should be noted that when the stockpile 3 reaches the set value, the DCS program will start the movement of the unloading trolley walking device 4, and the walking distance can be set by the position positioning code device 8 or can be set to a fixed distance according to the working conditions.

[0024] The belt conveyor 2 includes a support frame 10, an active roller 11, a driven roller 12, a driving motor 13 and a conveying belt 14. The active roller 11 and the driven roller 12 are rotatably connected at both ends of the support frame 10. The driving motor 13 is fixedly installed at one end of the side wall of the support frame 10, and the output shaft end of the driving motor 13 extends into the support frame 10 and is fixedly connected to the active roller 11. The conveying belt 14 is symmetrically arranged on the outside of the active roller 11 and the driven roller 12, and the active roller 11 and the driven roller 12 are connected through the conveying belt 14.

[0025] It should be noted that the control system provided in the device controls the drive motor 13 to rotate the active roller 11, and through the transmission connection between the active roller 11 and the driven roller 12, the coal on it is driven and transported to the belt conveyor unloading trolley 1 under the action of the conveyor belt 14.

[0026] A conveyor belt 15 is arranged on the top of the belt conveyor unloading trolley 1, and the conveyor belt 15 is arranged obliquely. The height of the conveyor belt 15 at one end of the unloading chute 5 is higher than the height of the conveyor belt 15 at one end of the belt conveyor 2.

[0027] It should be noted that the coal transported to the belt conveyor unloading trolley 1 can be lifted to a certain height through the conveyor belt 15 so that it can be placed at the unloading chute 5. The material can be dropped into the stockpile through the unloading chute 5 to form a pile 3. At the same time, the inclined conveyor belt 15 saves more length space.
