Description

Technical Field

[0001] This invention relates to the field of coal mining equipment technology, specifically to an automatic unloading coal loading device for coal mining. Background Technology

[0002] Coal, as one of my country's important basic energy sources, has long occupied a dominant position in industrial production and energy supply. With the continuous increase in coal mining depth and the increasing complexity of the mining environment, the safety, efficiency, and labor intensity of underground coal mining operations have become increasingly prominent issues. Traditional coal mining operations mainly rely on coal mining machines or tunneling machines to cut coal, which is then loaded and transported manually or by loaders.

[0003] However, the above solution still has the following problems: Traditional buckets have a fixed angle: they cannot dynamically adjust the tilt angle according to the height and slope of the coal pile, resulting in low loading efficiency and poor adaptability; Additional water trucks are required, but the coverage is uneven and the water consumption is high. External dust suppression equipment is inefficient. The pure diesel power design makes the equipment movement dependent on the fuel engine, and it cannot operate in areas where underground power supply is difficult, which cannot meet the needs of normal use. Therefore, the present invention needs to design an automatic unloading coal mining and loading device to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic unloading coal loading device for coal mining, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic unloading coal loading device for coal mining, comprising a bottom fixing frame: An electrical control box is fixedly connected to the top of the bottom fixed frame. A fixed base is fixedly connected to one side of the electrical control box. A loading mechanism, including a loading bucket, is installed above the fixed base.

[0011] In a preferred embodiment of the present invention, valves are fixedly connected to the outer side of each spray nozzle, a drain valve is installed on one side of the spray mounting bracket, and a water inlet is provided on one side of the water storage tank. Water is supplied to the inside of the water storage tank through the water inlet.

[0012] In a preferred embodiment of the present invention, a bottom support frame is installed at the bottom of the rotating baffle, and a counterweight rod is installed inside the bottom support frame. An internal limiting plate is fixedly connected to one side of the first rotating frame, and both sides of the internal limiting plate are connected to the corresponding rotating baffle.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention features a bottom fixed frame, an electrical control box, and a water storage tank. During outdoor operations, solar energy is collected and processed using solar panels, then converted into electrical energy with the assistance of a charging controller. DC power is stored in a battery compartment, and AC power is assisted by an inverter when needed, thus improving the equipment's flexibility. Four moving wheels drive the entire device for easy movement. A mounting plate secures the wheels and the bottom of the fixed frame, while multiple positioning bolts position the loading mechanism and the bottom fixed frame, facilitating quick assembly and disassembly during maintenance and reducing manual labor intensity. An internal limiting plate connects the first rotating frame and the rotating baffle. The operation of two first electric telescopic rods causes the rotating baffle to rotate slightly, while the operation of the second electric telescopic rod causes the first adjusting plate to rotate inside the first rotating frame, thereby adjusting the angle of the loading bucket's water storage tank and the first mounting block on one side. This allows for adjustment of the loading bucket's angle during loading. A bottom support frame and counterweight rod at the bottom of the rotating baffle are used for flexible adjustment of the loading mechanism. The loading mechanism automates coal mining operations, facilitating remote equipment control; the drive mechanism ensures the overall equipment can move normally to different work locations, meeting various scenarios and improving equipment flexibility; the power supply mechanism provides power to some electrical equipment during outdoor operations, saving overall operating costs to some extent; and the sprinkler system assists in cleaning the work site after mining, reducing the labor intensity of manual cleanup.
