Roadway slotting machine for coal mine

Abstract

The invention provides a roadway slotting machine for coal mines, which belongs to the technical field of underground equipment for coal mines, and includes a traction part, a cutting part, and a steering assembly connecting the traction part and the cutting part for providing power for the roadway slotting machine for coal mines And the supporting leg system for supporting the traction part and the cutting part; the cutting part includes a frame and a cutting arm assembly; the cutting arm assembly includes a base, an angle adjustment cylinder, a main arm, a main arm rotary drive assembly, a swing arm, Connecting rod Ⅰ, connecting rod Ⅱ, swing arm cylinder and cutting head. The above-mentioned roadway slotting machine for coal mines has a simple structure and a wide range of roadway adaptability. It is equipped with an intelligent cutting system, which can realize automatic cutting, and can open all the grooves around the roadway after one positioning.

Description

technical field [0001] The invention belongs to the technical field of coal mine underground equipment, and specifically discloses a roadway slotting machine for coal mines. Background technique [0002] In coal mine underground roadway construction operations, based on ventilation or safety requirements, it is necessary to install dampers or airtight roadways in the roadway. These two operating procedures need to be slotted around the roadway first. At present, the slotting operation mainly relies on manual labor. The use of breaking hammers for construction is not only inefficient, but also has great potential safety hazards. Some mines use mechanized slotting equipment. Among them, the equipment described in the patent "Underground Slotting Machine for Coal Mine (201710990248.0)" has the disadvantage of complicated mechanism for manipulating the mechanical arm, and it is impossible to slot directly under the equipment after one positioning. The patent "A Coal Mine Roadwa...

[0002] In coal mine underground roadway construction operations, based on ventilation or safety requirements, it is necessary to install dampers or airtight roadways in the roadway. These two operating procedures need to be slotted around the roadway first. At present, the slotting operation mainly relies on manual labor. Using a breaker for construction is not only inefficient, but also has great potential safety hazards

Some mines use mechanized slotting equipment. Among them, the equipment described in the patent "Underground Slotting Machine for Coal Mine (201710990248.0)" has the disadvantage of complex manipulation of the mechanical arm mechanism, and it is impossible to slot directly under the equipment after one positioning

The patent "A Coal Mine Roadway Grooving Machine (201510818526.5)" describes that the mechanical arm needs to be stretched and stretched with load during the working process, and the wear is serious, and neither of the two solutions has a material cleaning device, that is, for the width of the groove to be greater than the width of the cutting drum In certain working conditions, multi-knife operations are required, and manual cleaning of blanking is required between two operations.

According to market research, there is currently no effective slotting equipment on the market
