Dust-free rock electric drill for rock and soil exploration

Abstract

The invention relates to the field of rock electric drills, in particular to a dust-free rock electric drill for rock and soil exploration. The dust-free rock electric drill comprises a rock electricdrill and a dust removal mechanism, wherein the dust removal mechanism is arranged on the side of the rock electric drill and comprises a dust removal box and a dust catching hood; the dust catching hood is arranged on one surface, far away from an electric drill driving device, of a drill rod support frame, and is arranged outside a drill rod and a drill bit in a sleeving manner; the dust removalbox is arranged on a guide rail support; the dust removal box and the dust catching hood are connected through a dust removal pipeline; the dust removal box comprises a collecting box, a draught faninstalling box, a baffle plate and a filter; the draught fan installing box is arranged on the top end of the collecting box; the baffle plate is arranged inside the collecting box; a certain gap is formed between one end of the baffle plate and the collecting box; and the filter is arranged at the gap. By arranging the dust removal mechanism, the dust-free rock electric drill effectively reducesthe splashing of dust on the working surface, improves the environments of the working surface and the working environment of workers, reduces the potential safety hazards of the working surface, andeliminates the hidden danger of coal dust in wells.

Description

technical field [0001] The invention relates to the field of rock electric drills, in particular to a dust-free rock electric drill for rock and soil exploration. Background technique [0002] Rock electric drill is a tool for rock blasting, which is suitable for underground coal mine roadway excavation, mining, water conservancy construction, road construction and stonework engineering operations. It can also drill water injection holes, deep water holes and visit gas holes in coal seams. In actual production, when the top-coal loosening blasthole is arranged, the cinder and dust withdrawn from the blasthole will slide and scatter freely, which will generate more dust. The current dust reduction and dust removal method still uses spray treatment, but the drill bit rotates at high speed during the drilling process, and its The amount of dust generated is large, and there may be large air volume and high wind speed on the working surface. The spray method can only deal with p...
