Description

Technical Field

[0001] The utility model relates to the technical field of coal seam mining equipment, in particular to a coal seam mining device. Background Art

[0002] Coal drill rods are used in conjunction with various pneumatic anti-burst drills. They use spiral drilling technology and have the characteristics of fast drilling speed, good hole forming, and high drilling efficiency. Compared with traditional drilling, the speed is greatly increased. The impact of drilling construction on the progress of coal seam excavation is reduced to the minimum, and it is widely used in drilling and mining of coal mines, gypsum mines, etc.

[0003] The existing Chinese utility model patent with reference announcement number CN221002731U discloses a deep coal seam mining device, including an operating table, a fixed plate is fixedly installed on the left side of the operating table near the bottom, a lifting device is arranged on the fixed plate, a power device is arranged on the mining device, a first circular groove is opened in the middle position of the fixed plate, the mining device is arranged on the first circular groove, a conveyor belt is arranged on the left side of the operating table, two first grooves are opened at the front and rear ends of the fixed plate, first reversing motors are fixedly installed inside the two first grooves, the output ends of the two first reversing motors pass through the upper surface of the fixed plate and are fixedly connected with first threaded rods, and the two first threaded rods are rotatably installed on the upper surface of the fixed plate, which solves the problem that when multiple drill rods are connected to increase the length of the drill rods, there is a certain probability that the connection between two or more drill rods will loosen when the threaded connection is basically rotated in the opposite direction, so that coal mine powder enters the interior and has a certain impact on the drill rod.

[0004] The existing coal seam mining equipment has insufficient stability during use. When the drill rod drills downward, the reaction force easily lifts the mining equipment, thereby affecting the use and mining of the equipment. At the same time, the existing coal seam mining equipment is not easy to guide and discharge the soil mined during coal seam mining, and it is easy to accumulate at the drilling position.
