Abstract

The invention relates to devices for drilling horizontal wells. The goal is to increase the productivity of transportation and reduce metal consumption. The drilling rig for horizontal drilling machines includes a shaft 1 with rotary cutting knives 2 and conveying blades (TL) 3. Each TL 3 is made in the form of a flat blade and set at an acute angle. The TL 3s are fixed on the shaft 1 by means of a hinge assembly with the possibility of fixed rotation relative to the shaft 1. The TL 3s are located along a helical line with a certain pitch and are installed with partial overlapping one another to form a continuous flow of the transported material. The hinge assembly is connected to the TL 3 with the shaft 1 suspended in the form of the shaft 1 placed in the through holes of the shaft 1 and rigidly connected to the TL 3 finger. The shank of the latter has a U-shaped notch for placement of the latch-latch plate. The plate has a dihedral angle. When drilling a well, stavu rotate in one direction or another and serve to the bottom. Cutting knives 2 destroy the face. Products of destruction interact with TL 3, which rotate around the longitudinal axis of the fingers. The angle of rotation of the TL 3 is limited by the dihedral angle of the latch plate. 1 hp f-ly, 5 ill. 8 s% KOVB39

The invention relates to the mining industry, in particular to devices for drilling horizontal wells.

The purpose of the invention is to increase the productivity of transportation and reduce metal consumption.

FIG. 1 shows a drilling rig, a general view; in fig. 2 - view A on

FIG. one; in fig. 3 shows the transport scheme for products of destruction by a paddle; in fig. 4 — node I in FIG. one; in fig. 5 is a section BB in FIG. four.

A drilling rig for a horizontal drilling machine consists of a shaft 1 with rotary cutting knives 2 and conveying blades 3, which are made in the form of flat blades and fixed in planes perpendicular to the longitudinal axis of the shaft 1 along a helical line with a certain pitch. The blades 3 are installed at an acute angle to the longitudinal axis of the shaft 1 and are connected to the latter by means of a hinge assembly, which is made in the form of fingers 4 placed in through holes of the shaft 1, with which the blades are rigidly connected.

The front faces 5 of the transporting blades are directed towards the bottom of the well, and the rear faces 6 are directed toward the transport side. To the outer surface of the shaft 1 from the side of the protruding shank of the finger 4 there is a rigidly attached latch-cap 7.

In the cylindrical surface of the body of the finger 4, a U-shaped groove 8 is formed, the two planes of which are perpendicular to the longitudinal axis of the finger, and the perpendicular to the conveying surface of the blade parallel to the longitudinal axis of the finger and can be pressed to one of the faces 9 of the dihedral angle the latch plate 10 krshpsi 7.

The plate 10 is placed in the U-shaped groove 8, and the shank of the finger 4 is placed inside the latch cover 7. The distance between the face 9 of the dihedral angle of the plate 10 and the opposite inner surface of the latch clamp 7 is not less than the diameter of the finger 4.

The device works as follows.

in a way.

When drilling a well, the drill station is rotated around its axis in one or the other direction and is fed to the bottomhole. In this case, the cutting knives 2 destroy the blade, and the destruction products interact with the transport blades, which as a result of the interaction rotate around the longitudinal axis of the fingers 4, and their angle of rotation is limited by a two-sided angle of the Kr-blade-clamp plate 10 7. In this case, the transport blade 3 deviates from the longitudinal axis of the drill rod in the opposite direction of rotation.

Claims (1)

1. A drilling rig for horizontal drilling machines, including a shaft with rotary cutting knives, on which, in planes perpendicular to its longitudinal axis, transporting blades are arranged along a helical line with a certain pitch, characterized in that, in order to increase transport performance and metal consumption reduction; each transporting blade is made in the form. flat blades and installed at an acute angle to the longitudinal axis of the shaft, while the blades are fixed on the shaft by means of a hinge assembly with the possibility of a fixed rotation relative to the latter and installed with partial overlapping one another to form a continuous stream of material being transported. 2, A drilling rig as claimed in claim 1, characterized in that the hinge assembly is designed as placed. in the through holes of the shaft and a finger rigidly connected to the blade, the tail of which has a U-shaped cut-out for placement in the latter having a dihedral angle plate of the retainer-krppki.
