Description

Technical Field

[0001] This utility model relates to the field of coal mine mining technology, specifically to a high-efficiency sidewall mining equipment for mining. Background Technology

[0002] Coal mines are areas where humans extract coal resources from coal-rich areas, generally divided into underground coal mines and open-pit coal mines. In underground coal mines, the coal seams are far from the surface, typically requiring the excavation of underground tunnels. In open-pit coal mines, the coal seams are closer to the surface, allowing for direct extraction by stripping away the surface soil. Open-pit coal mines offer advantages such as shorter construction time, lower investment per unit of ore, higher labor productivity, lower mining costs, higher mining intensity, and larger production scale, leading to their widespread application globally. During open-pit mining, to ensure slope safety, a certain slope angle must be maintained as the mine gradually descends from the surface. However, this slope protection results in some coal resources being buried beneath the slope; this stagnant coal is known as slope coal. Slope coal is a problem that cannot be avoided by existing stepped, slope-retaining open-pit mining methods and processes in my country, causing significant resource waste. Furthermore, the buried coal also poses a potential risk of spontaneous combustion.

[0003] Sidewall coal mining technology maximizes the extraction of coal resources from sidewalls while minimizing damage to surface soil and vegetation. This technology has significantly lower extraction costs than conventional open-pit coal mining. A utility model patent with application number 202122011711.7 discloses a high-efficiency sidewall coal mining device. By incorporating a lifting and extending mechanism and a drill bit, it can first fracture harder coal before using digging rollers for extraction, thus improving the recovery rate of sidewall coal to some extent. However, because this patent uses a lifting mechanism inside a connecting plate to drive the digging rollers up and down, and uses a third hydraulic cylinder inside a connecting block fixed to the left side of the lifting mechanism as the power source for the digging rollers' extension and retraction, the movement range of the drill bit and digging rollers is limited, making it impossible to flexibly adjust the working angles of the drill bit and digging rollers according to different slope conditions. Utility Model Content

[0004] To address the technical problem that existing side slope coal mining equipment has limited movement range of drill bits and digging rollers, making it impossible to flexibly adjust the working angles of drill bits and digging rollers according to different slope conditions, this utility model provides a high-efficiency side slope coal mining equipment for mining. It utilizes a first servo motor to drive the sleeve frame to rotate, thereby achieving drill bit angle adjustment, and utilizes a second servo motor to drive the second connecting plate to rotate, thereby achieving roller shaft angle adjustment, thus expanding the mining range of side slope coal.

[0005] The technical solution of this utility model is as follows:

[0006] A high-efficiency sidewall mining equipment for mining includes a mining vehicle body. A movable slot is opened at the front end of the mining vehicle body.

[0037] Working Principle: During operation, the mining vehicle is driven to the sidewall position. The hydraulic telescopic rod in the support assembly controls the fixed base plate to press against the ground, lifting the mining vehicle to a preset height. The first servo motor is activated, driving the drive rod to rotate. The drive rod, through a drive shaft of the socket frame fixedly connected to it, drives the socket frame to rotate around the output axis of the servo motor. Since the first and second limit sliders are fixed to the right and left front ends of the socket frame respectively, these sliders can slide along the first and second slide grooves. The front end of the socket frame can rotate within a certain angle range and accurately stop at any position corresponding to any rotation angle within that range. After adjusting the rotation angle of the socket frame's front end, the electric telescopic rod is controlled to adjust the extension length of the drill rod and drill bit. Then, the first drive motor is activated. The output end of the first drive motor drives the transmission rod to rotate, which in turn drives the drill rod and drill bit to rotate. The rotating drill rod and drill bit are used to mine the coal from the sidewall. During the mining process, after the coal on the sidewall is crushed and falls, the electric telescopic rod is returned to its original position, and the height of the mining vehicle is adjusted by the hydraulic telescopic rod. Then, the second servo motor is started. The output of the second servo motor drives the rotating rod to rotate, which in turn drives the connecting plate to rotate. This allows the roller to rotate to the position where the crushed coal falls in front of the mining vehicle. The second drive motor is then started, and its output drives the second movable rod to rotate. The second movable rod drives the roller to rotate, and the roller drives the digging plate on the surface to dig out the crushed coal. During the digging process, the angle of the digging plate can be adjusted as needed to facilitate coal digging. After digging is completed, the second servo motor can rotate the roller back to the top of the mining vehicle.
