Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] like Figure 1 and Figure 2 As shown:

[0037] Example 1: This utility model provides a novel intelligent raw coal loading and unloading device for coal mines, including a support platform assembly 1, a first conveyor belt 2, a second conveyor belt 3, a coal bunker mechanism 4, a first monitoring mechanism 5, and a second monitoring mechanism 6.

[0038] Support platform assembly 1 includes a support platform body 11, and a mounting bracket 12 is provided on the support platform body 11;

[0039] The first monitoring unit 5 and the second monitoring unit 6 are both fixedly installed on the mounting frame 12. The first transmission belt 2, the second transmission belt 3 and the coal bunker mechanism 4 are all set on the support platform body 11. The first transmission belt 2 transfers the raw coal to the second transmission belt 3 via the coal bunker mechanism 4.

[0040] Weighing sensors are installed on both conveyor belt 1 (2) and conveyor belt 2 (3);

[0041] The first monitoring agency 5 monitors the raw coal on conveyor belt 2, and the second monitoring agency 6 monitors the raw coal on conveyor belt 3.

[0042] As can be seen from the above, raw coal is placed on conveyor belt 2, and through the operation of conveyor belt 2, the raw coal is transported to coal bunker mechanism 4.

[0043] During the transmission process, the first monitoring agency 5 monitors the raw coal on the conveyor belt 2 in real time, including the flow rate and accumulation of the raw coal. The weighing sensor on the conveyor belt 2 measures the weight of the raw coal in real time to ensure that it will not be overloaded.

[0044] After the raw coal enters the coal bunker mechanism 4, it falls from the mechanism onto the second conveyor belt 3 for continued transport. Simultaneously, the weighing sensors on the second conveyor belt 3 measure the weight of the raw coal in real time to ensure that it is not overloaded.

[0045] During this process, the second monitoring agency 6 monitors the raw coal on the second conveyor belt 3 to ensure the stability and safety of the raw coal during the transmission process. The entire transfer process is automated, continuous and intelligent, which improves the transfer efficiency and safety.

[0046] like Figures 1 to 7 As shown:

[0047] Example 2: This example is basically the same as the previous example, except that the coal bunker mechanism 4 includes a coal bunker body 41. The bottom of the coal bunker body 41 is fixedly connected to a first shaft bracket 42 and a second shaft bracket 43. One end of the first shaft bracket 42 is rotatably connected to a sealing plate 44, and one end of the second shaft bracket 43 is rotatably connected to a hydraulic cylinder 45. The end of the hydraulic cylinder 45 is rotatably connected to the sealing plate 44.

[0048] The bottom of the coal bunker body 41 is equipped with drainage holes to prevent excessive water accumulation from causing the bunker walls to absorb too much coal, which could lead to a bunker collapse.

[0049] The hydraulic cylinder 45 can drive the sealing plate 44 to rotate around the shaft frame 42 and open and close the bottom of the coal bunker body 41.

[0050] Specifically, the first monitoring unit 5 includes a support assembly 51 and a material level monitoring assembly 52;

[0051] The bracket assembly 51 includes a bracket 511, on which a plurality of positioning holes 512 are provided;

[0052] The material level monitoring component 52 includes a radar level gauge 521. A sliding frame 522 is fixedly connected to the outside of the radar level gauge 521. A positioning rod 523 is slidably connected to one side of the sliding frame 522. A spring 524 is sleeved on the outside of the positioning rod 523.

[0053] The sliding bracket 522 is slidably embedded in the outside of the bracket 511, and the spring 524 drives the positioning rod 523 to move and embed into the positioning hole 512 for positioning;

[0054] The sliding frame 522 is slidably embedded in the outside of the bracket 511. The spring 524 drives the positioning rod 523 to move and embed into the positioning hole 512 for positioning, so that the operator can adjust the height of the radar level gauge 521 as needed.

[0055] Specifically, the first monitoring agency 5 also includes camera 53;

[0056] Camera 53 is fixedly mounted on bracket 511, and bracket 511 is fixedly mounted on mounting frame 12 after being passed through by screws.

[0057] Specifically, the second monitoring unit 6 includes a bracket 61 and a camera 62. The camera 62 is fixedly installed on the bracket 61, and the bracket 61 is fixedly installed on the mounting frame 12 through a screw.

[0058] Specifically, it also includes hydraulic control systems, electrical control systems, and display systems;

[0059] The hydraulic control system is used to drive the hydraulic cylinder 45 in the coal bunker mechanism to work;

[0060] The electrical control system includes a programmable logic controller (PLC). The PLC is responsible for processing data from the weighing sensor, radar level gauge, and camera, and judging the transfer status of the raw coal based on the data. It then issues corresponding control commands, and controls the hydraulic cylinder 45 to work and the start and stop of the first and second transmission belts 2 and 3 through the hydraulic control system.

[0061] The display system is used to display working status, monitoring data, and alarm information.

[0062] As can be seen from the above, after the operator starts the new intelligent raw coal loading device in the coal mine, the raw coal is sent into the coal bunker mechanism 4 through the conveyor belt 2.

[0063] The bottom of the coal bunker mechanism 4 is controlled by a sealing plate 44 driven by a hydraulic cylinder 45 to ensure that raw coal falls into the conveyor belt 2 3 as needed;

[0064] Meanwhile, the radar level gauge 521 of the first monitoring agency 5, combined with the sliding frame 522 and the spring 524 for positioning, monitors the raw coal level on the conveyor belt 2 in real time and provides visual monitoring through the camera 53.

[0065] The second monitoring agency 6 monitors the raw coal on the conveyor belt 2 3 through camera 2 62;

[0066] The electronic control system receives information from the weighing sensor. When it detects that there is too much raw coal on conveyor belt 2, it can appropriately reduce the speed of conveyor belt 2 or stop conveyor belt 2. When it detects that there is too much raw coal on conveyor belt 3, it can appropriately reduce the speed of conveyor belt 3 or stop conveyor belt 3. It can also control the hydraulic cylinder 45 through the hydraulic control system to realize the opening and closing of the coal bunker mechanism 4. Throughout the process, the display system displays the working status, monitoring data and alarm information in real time to ensure the safety and efficiency of the transfer process.
