Abstract

The invention is suitable for the technical field of coal mining equipment, and provides a coal mine roadway angle adjusting type tunneling system. The tunneling system comprises a base, wherein a driving structure is arranged in the base, a buffer structure, an angle adjusting structure and a tunneling structure are sequentially arranged on the upper portion of the base, the angle adjusting structure comprises an angle adjusting plate, the angle adjusting end of the angle adjusting plate is movably connected with an arc-shaped groove of the auxiliary adjusting plate, a plurality of angle adjusting assemblies are arranged at the bottom of the angle adjusting plate, the tunneling structure comprises a supporting table, the supporting table is rotationally connected with a main rotating shaft, one end of the main rotating shaft is fixedly connected with a rotating seat, a plurality of branch rotating shafts are rotationally connected to the rotating seat, and the ends, away from the rotating seat, of the branch rotating shafts are provided with spiral blades. According to the tunneling system, tunneling operation at different heights can be conducted in the mine, the tunneling effectis good, meanwhile, the safety and stability of the tunneling system are high, and the service life of the tunneling system is prolonged.

Description

technical field [0001] The invention relates to the technical field of coal mining equipment, in particular to an angle-adjustable tunneling system for coal mine roadways. Background technique [0002] Areas where humans exploit coal resources in coal-rich mining areas are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far away from the surface, it is generally selected to excavate the coal by digging the roadway underground, which is an underground coal mine. The vast majority of coal mines in my country are underground coal mines. Coal mines include large areas above and below ground and associated facilities. A coal mine is a reasonable space excavated by humans when excavating geological layers rich in coal, usually including roadways, shafts, and mining faces. [0003] When the coal mine excavation work in the prior art is in progress, it can only be excavated at a single point normally, and it cannot be excavated at mult...
