Abstract

The invention discloses a mining roadway grooving machine which comprises a fixed base, an overturning base, a rotary drive, a cantilever and a milling and digging head. The fixed base comprises two fixed beams which are arranged in parallel, and a connecting beam is fixedly arranged between one ends of the two fixed beams; the bottom face of an overturning frame of the overturning base is hinged to the fixed beam. An overturning hydraulic cylinder is arranged between the overturning frame and the fixed base; the rotary driver is fixed on a cylinder barrel of a double-rod hydraulic cylinder of the overturning base; a fixed arm of the cantilever is hinged with a rotary disk of the rotary drive; a cantilever swing hydraulic cylinder is arranged between the rotary disc and the fixed arm, a cylinder barrel of the cantilever swing hydraulic cylinder is hinged to the rotary disc, and a piston rod of the cantilever swing hydraulic cylinder is hinged to the fixed arm; and a milling and digging head is arranged on a rocker arm of the cantilever. The device has the advantages of reducing heavy physical labor, being safe and efficient, ensuring engineering quality, increasing mine production and construction speed, improving working benefits, reducing labor input, replacing people with machines and reducing link cost.

Description

Technical field: [0001] The invention relates to underground mining equipment, in particular to a mining roadway slotting machine. Background technique: [0002] Coal is the cornerstone of my country's energy security and is of great importance to national economic security. The occurrence conditions of coal seams in my country are various, including medium-thick coal seams and thin coal seams, and the mining conditions are different. There are great differences in the mining scale, technical equipment and mining methods of coal mines in different regions. [0003] Thin coal seams account for a large proportion of the current proven reserves. Since the thin coal seam brings greater difficulty to mining, all the downhole equipment must be miniaturized. At present, the existing slotting machines in China are not suitable for slotting operations in thin coal seam roadways. Temporary building of wind walls, slotting of permanently sealed walls, digging of water pump nests in j...
