Abstract

A spraying and dust falling device for a rock drill comprises the rock drill, water storage chambers and mechanical seals. A rock drill towing rod is connected to the head end of the rock drill. An annular atomizer A is fixedly connected to the outer wall of the head end of the rock drill and is connected with an annular atomizer B rotationally in a sealed mode through the two sets of mechanical seals. The annular atomizer A and the annular atomizer B are each internally provided with one water storage chamber. An atomization nozzle is inlaid in the annular atomizer B. An annular protective cover is connected to the outer wall of the annular atomizer B. The annular atomizer B and the rock drill towing rod through six connecting rods. According to the design of the annular atomizers, when the rock drill is used, water spray sprayed out by the annular atomizers makes contact with dust diffused at the rock drill towing rod, thus the effect of dust falling through water is achieved, the dust does not block the sight of an operator, and the problems that the dust is breathed into the body by the operator, and an adverse effect occurs to the body of the operator can also be avoided.

Description

technical field [0001] The invention relates to the technical field of dust removal, in particular to a spray dust suppression device for a rock drilling machine. Background technique [0002] The rock drill is a rock drilling equipment widely used in mining. When the rock drill is working, the engine drives the blower to run. The blower supplies the rock drill with high-pressure gas continuously. The high-pressure gas reaches the bottom of the hole through the drill rod center hole and the drill nozzle in the rock drill. The rock slag produced during the perforation process is blown out of the hole, which is convenient for further drilling. Some rock drills also use high-pressure water to clean the rotor hole. No matter what the method is, there will always be dust flying out of the rotor hole opening, especially when the rotor hole is cleaned with high-pressure air. [0003] The inventors have found that during the drilling process of existing rock drills, under the actio...
