Description

Technical Field

[0001] This invention relates to the field of coal loading technology, specifically to a coal transportation and loading equipment. Background Technology

[0002] With the increase in mine output and the intensification of safety management, the efficiency of local sales and transportation has become one of the factors restricting mine production. The traditional method of transporting local coal uses engineering vehicles for loading, which is not only inefficient and labor-intensive, but also poses a great threat to the safety management of coal yards, thus creating limitations and bottlenecks in the transportation of local coal and seriously restricting the transportation of local coal from mines.

[0003] Currently, in existing coal transportation and loading equipment, the coal bunker's unloading opening is mostly fixed. However, the cargo compartments of engineering vehicles are long, meaning that only a portion of the cargo compartment can be loaded at a time. After loading, the vehicle must be repositioned for even distribution, which is time-consuming, labor-intensive, and results in uneven loading, thus affecting the efficiency of coal transportation. Therefore, to improve the efficiency of coal transportation and loading, and to promote technological advancement and enhance core technological competitiveness in the industry, this application proposes a new implementation scheme that differs from existing coal transportation and loading structures and application methods. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a coal transportation and loading device, mainly to solve the problem that the unloading ports of existing coal bunkers are mostly fixed installations, while the cargo compartments of engineering vehicles are long, so only a part of the cargo compartment can be loaded during loading. After loading, the position of the engineering vehicle needs to be adjusted to ensure even loading, which is not only time-consuming and labor-intensive, but also results in uneven loading.

[0041] The working principle of this embodiment is as follows: In use, the coal truck is first driven to a position below the unloading hopper 201. At this time, the discharge valve 103 of the coal bunker 1 outlet 102 opens, and coal falls into the receiving box 2. Then, it falls along the unloading hopper 201 into the coal truck's carriage. Simultaneously, the motor 502 on one side of the unloading hopper 201 starts, driving the rotating disk 503 to rotate. The sliding shaft 504 on the rotating disk 503 slides along the guide hole 506 on the guide plate 505. Therefore, the rotation of the rotating disk 503 can drive the guide plate 505 and the dispersing plate 5 to swing back and forth, allowing the coal to be evenly loaded into the carriage. The radar level gauge 9 can accurately monitor the coal height in the car. When the height reaches the set value, the drive motor 302 starts, which drives the gear 301 to start. The gear 301 meshes with the tooth groove 207, thereby driving the first sliding plate 205 to slide left and right along the first slide rail 3, thereby adjusting the position of the hopper 201 above the car. Due to the position shift, the coal falling from the discharge port 102 may fall onto the first conveyor belt 202 or the second conveyor belt 203. The first conveyor belt 202 and the second conveyor belt 203 are set opposite to each other, carrying the coal into the hopper 201, and thus into the car.

[0042] At the same time as the material is discharged from the discharge port 102, the spray pump 603 starts, spraying liquid through the coil 601 along the atomizing nozzle 602 to reduce dust on the coal being discharged.

After the detection is completed, the material is unloaded. The overall weight of the vehicle can be monitored. By subtracting the weight of the vehicle itself, the loading weight of the coal can be accurately detected.
