Energy-saving coal mine large-batch mining equipment and method thereof

Abstract

The invention discloses energy-saving coal mine large-batch mining equipment which comprises a walking mechanism. Lifting oil cylinders are fixedly arranged on a chassis of the walking mechanism and located at the four corners of the chassis, a lifting plate is fixedly arranged on a plane formed by the action ends of piston rods of the lifting oil cylinders, and a feeding swing arm mechanism is further arranged on the lifting plate; the feeding swing arm mechanism comprises a pitching oil cylinder, a swing arm and a hydraulic motor, one end of the swing arm is hinged to the top surface of the lifting plate, the other end of the swing arm extends leftwards to the outer side of the lifting plate, a cylinder barrel of the pitching oil cylinder is hinged to the lifting plate, a piston rod of the pitching oil cylinder is hinged to the swing arm, and a platform is fixedly arranged at the bottom of the mounting plate; and the hydraulic motor is fixedly arranged on the top surface of the platform, an output shaft of the hydraulic motor penetrates through the platform, a truss is installed at the extending end, and a drilling device and a fracturing device are arranged at the left side and the right side of the truss correspondingly. The energy-saving coal mine large-batch mining equipment has the beneficial effects of saving energy consumption, improving the economic benefit of a coal mine plant, mining coal in batches and improving the mining efficiency.

Description

technical field [0001] The invention relates to the technical field of coal seam mining, in particular to energy-saving coal mine mass mining equipment and a method thereof. Background technique [0002] Coal mines refer to coal-rich mining areas. Coal mines are divided into underground coal mines and open-pit coal mines. Compared with underground coal mines, open-pit coal mines are easier to mine, and open-pit coal mines are distributed on the surface and mountain slopes. The coal mines on the mountain slopes are It is more difficult than the coal mines on the surface, but the slopes are also resources, no matter how difficult it is, we must find a way to mine them. At present, the coal mine mining method of the coal mine on the slope of the mountain is: the driver first drives the crushing engineering vehicle to the front of the mountain, and then operates the crushing engineering vehicle to make the crushing head on the crushing head continuously chisel towards the coal s...

AI Technical Summary

Problems solved by technology

Yet, although this mining method can realize the mining of coal mine, some practitioners or mining engineers still find that there is following defect in this mining method: 1, there is only a crushing head on the crushing engineering vehicle, and the coverage area of ​​the coal seam is relatively small. Large, so it takes a long time to work to knock down all the coal in the coal seam, which reduces the mining efficiency

2. When the coal seam is hit every time, only a small amount of coal falls, and there is a technical defect of a small amount of mining, which further increases the mining time and reduces the mining efficiency

3. The screening machine also needs to consume a lot of power to vibrate the screen when it is working, which undoubtedly increases the power consumption and thus increases the mining cost
