Abstract

A novel shake-proof noise-reduction rock drill comprises a shock absorption handle, a cylinder cover, a cylinder block, a movable plug, a drill rod, a cylinder seal cover and a locking ring, wherein the movable plug is connected with a power part of the rock drill, the drill rod is connected with a work part of the drill rod, an oil retainer on the movable plug is provided with a certain number of small holes, a liquid cavity between the cylinder block and the movable plug and a buffering cavity between the movable plug and the drill rod are filled with hydraulic oil, and a spring is arranged between the cylinder seal cover and the locking ring. The novel shake-proof noise-reduction rock drill is simple in structure, firm, durable, small in resistance coefficient, and high in noise reduction quantity, reduces vibration impact and noise interference to an operator during drilling operation, makes the operator fell more comfortable, and prevents the operator from mind and body injury and health hidden danger.

Description

technical field [0001] The invention relates to a rock drill, in particular to a novel shockproof and noise-reducing rock drill. Background technique [0002] Rock drills are mainly used for roadway operations in mining and roadway excavation, and are also important tools in railway, water conservancy construction and national defense masonry projects. A rock drill is a machine that drills holes in rocks. Its main working principle is to use air pressure as the power to control the reciprocating motion of the piston through a passive valve, constantly hitting the fiber tail, and crushing the rock under the impact force to form a strong force. Shock noise and vibration. Since the rock drill is a light-duty manually operated machine, the operator needs to directly hold the operating handle with his hands. Under long-term operation, the vibration and noise will bring physical and mental harm to the operator and hidden health risks. Contents of the invention [0003] The tec...
