Abstract

The invention discloses an eccentric rock drill which comprises a frame, a first motor, a rotating flexible shaft, a rotating shaft, an eccentric block, an impact piston, an end cover and a shank. The eccentric rock drill is ingenious in structure, powerful in function, simple to operate, low in cost and convenient to maintain. By use of the eccentric rock drill, a series of problems that a conventional hydraulic rock drill is high in machining and manufacturing difficulty and poor in high pressure sealing effect, stepless frequency modulation cannot be achieved, and the efficiency of linear impact energy is low are solved thoroughly, and the using efficiency of the eccentric rock drill and users' working efficiency are greatly improved.

Description

technical field [0001] The invention relates to a rock drilling machine, in particular to an eccentric rock drilling machine. Background technique [0002] Hydraulic rock drills use the principle of high-pressure hydraulic oil to force the impact piston to reciprocate at high speed in the cylinder body. Therefore, there are relatively high requirements for materials, heat treatment, and machining accuracy, which results in high manufacturing costs and high maintenance costs for current hydraulic rock drills. , and the processing and manufacturing of hydraulic rock drills is difficult, the high-pressure sealing effect is poor, the stepless frequency modulation cannot be realized, and the efficiency of linear impact power is low. In view of the above defects, it is necessary to design an eccentric rock drill. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an eccentric rock drilling machine to solve the problems of...
