Embodiment Construction

[0017] see figure 1 , figure 2 and image 3 In this embodiment, the structural form of the pneumatic rotary guiding and propelling drilling rig is as follows: a guiding and positioning sleeve 3 in the shape of a barrel is provided, an air motor 4 is fixedly arranged in the guiding and positioning sleeve 3, and the tail air intake duct 6 of the air motor 4 is guided The tail end of the positioning sleeve 3 protrudes and is externally connected to the air intake drill pipe 2. The front exhaust orifice plate 1 of the air motor 4 is fixedly installed on the front end of the guiding positioning sleeve 3 by using lugs. The rotating shaft of the air motor 4 is positioned on the guide The front end of cover 3 protrudes, and drill bit 5 is installed.

[0018] The diameter of the inner cavity of the guide positioning sleeve 3 is set to be larger than the outer diameter of the air motor 4, so that an axially penetrating annular channel is formed between the guide positioning sleeve 3 ...

Abstract

The invention discloses a pneumatic rotating guide propulsion drilling machine, which is provided with a guide positioning sleeve in a round barrel body shape. A pneumatic motor is fixedly arranged inthe guide positioning sleeve; a tail part air inlet guide pipe of the pneumatic motor convexly extends from the tail end of the guide positioning sleeve; an air inlet drilling pipe is externally connected; a front end exhaust hole plate of the pneumatic motor is fixedly arranged on the front end surface of the guide positioning sleeve through a convex lug; a rotating shaft of the pneumatic motorconvexly extends from the front end of the guide positioning sleeve and is provided with a drill bit. The horizontal directional propulsion can be effectively performed in real time, and is particularly applicable to the construction of underground perforation horizontal directional hole drilling and reaming.

Description

technical field [0001] The invention relates to a directional propulsion tool used in a horizontal directional drilling machine. Background technique [0002] At present, the method of trenchless horizontal directional drilling for laying pipelines has been widely used. However, due to the rear power of the horizontal directional drilling machine, the horizontal direction of the drilling machine cannot be effectively controlled. Contents of the invention [0003] The present invention is to avoid the shortcomings of the above-mentioned prior art, and provides a pneumatic rotary steerable propulsion drilling rig, which can effectively carry out horizontal directional propulsion in real time, and can be applied in the construction of underground drilling horizontal directional drilling and reaming. [0004] The present invention adopts following technical scheme for solving technical problems: [0005] The structural features of the pneumatic rotary guiding and propelling d...
