Abstract

The invention discloses a hydraulic oil oil-return device for a hydraulic type drilling machine. The hydraulic oil oil-return device comprises a hydraulic oil oil-return inlet pipe (1) and a hydraulic oil oil-return outlet pipe (2). An inlet (11) is formed in one end of the hydraulic oil oil-return inlet pipe (1). A first installing hole (12) is formed in the upper end of the inlet (11). An outlet (21) is formed in one end of the hydraulic oil oil-return outlet pipe (2). A second installing hole (22) is formed in the upper end of the outlet (21). A plurality of middle oil-return pipes (3) are arranged between the hydraulic oil oil-return inlet pipe (1) and the hydraulic oil oil-return outlet pipe (2). The hydraulic oil oil-return device for the hydraulic type drilling machine has the advantages of being reliable in oil-return transportation, not prone to blocking, convenient to use, long in maintenance period, simple in structure and low in cost.

Description

technical field [0001] The invention relates to a hydraulic oil return device for a hydraulic drilling machine. Background technique [0002] The hydraulic drilling machine is a drilling operation machine based on hydraulic pressure. In actual work, it is found that the return oil of the hydraulic oil of the hydraulic drilling machine often contains more sundries in the oil pipeline, so the sundries accumulate and precipitate, which may easily cause blockage of the oil return pipeline. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hydraulic oil return device for a hydraulic drilling machine which has reliable oil return transmission, is not easy to be blocked, is convenient to use, has a long maintenance period, simple structure and low cost. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A hydraulic oil retur...
