Problems solved by technology

[0002] Existing drilling equipment used for oil exploration generally realizes drilling through drill bits, and realizes collecting soil through air pipes while drilling holes, but air pipes can only realize the absorption of small particles of earth. The trachea can’t absorb the granular soil well, and it’s easy to make the drill bit stuck. At the same time, the drill bit works for a long time, which makes the drill hair hot, which will reduce the service life of the drill bit.

Abstract

The invention relates to a drilling device for oil exploration. The drilling device comprises a connecting rod, a first rotating rod, a second rotating rod and a connecting mechanism, wherein the connecting mechanism comprises a driven assembly and a limiting assembly. According to the drilling device for oil exploration, the first rotating rod and the second rotating rod are rotated through the connecting mechanism, when the first rotating rod rotates forwards, the second rotating rod is rotated reversely through the driven assembly, meanwhile, the second rotating rod is accelerated, so that the second rotating rod can better realize hole rotation, a pull rope is always in a tightened state through the restoring force of a torsional spring; meanwhile, the first rotating rod and the second rotating rod are elastically fixed through an abutting assembly, so that the use practicability is improved; and moreover, the soil can be cut through the opposite rotating directions of the first rotating rod and the second rotating rod, so that the soil can be better absorbed by an air pipe, and the mud discharging effect is improved.

Description

technical field [0001] In particular, the invention relates to a drilling device for oil exploration. Background technique [0002] Existing drilling equipment used for oil exploration generally realizes drilling through drill bits, and realizes collecting soil through air pipes while drilling holes, but air pipes can only realize the absorption of small particles of earth. The trachea can't absorb the granular soil well, and it is easy to make the drill bit stuck. At the same time, the drill bit works for a long time, which makes the drill hair hot, which will reduce the service life of the drill bit. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a drilling device for oil exploration in order to overcome the deficiencies of the prior art. [0004] The technical solution adopted by the present invention to solve the technical problem is: a drilling equipment for oil exploration, including a connecting rod, a f...
