Description

12

The invention relates to the mining industry, namely to the executive bodies of auger-drilling machines, drilling minerals with the breaking of interwell wells.

The purpose of the invention is to increase the productivity of a drilling machine by enabling the use of one size of a movable rod, regardless of the center-to-center distance of the cutting crowns.

Figure 1 shows the Executive body, located in a passable development, a general view; figure 2 - section aa in figure 1, with the extreme left position of the cutting rod; on fig.Z - the same, with its extreme right position.

The executive body of the auger screw maschina consists of drill bits I and 2, parallel to the located branches of the transporting screw sections.

3 and 4, supporting lamps 5 and 6 with a clamp 7, a break rod 8 fixed to the front wall of the slide 9 mounted on the clip 7 attached to the rear wall of the slide 9, a connecting rod 10 with a sleeve 11 covering the crank 12 in as an eccentric mounted on the shaft 13 of one of the branches of the conveying screw sections (figure 1 shows the right

Branch 4).

The slider 9 is connected to the connecting rod 10, and the latter - with the sleeve 11 spatial hinges 14 and 15 (for example, ball bearings).

The proposed executive body of the auger machine works as follows.

The drill bits 1 and 2 are supplied to the bottom by the branches of the transporting screw sections 3 and 4 and, while rotating the latter, they destroy the mineral massif. At the same time, as a result of the interaction of the sleeve 11 with the crank 12 of the shaft 13 of the right 4 branch of the conveying screw sections, the connecting rod 10 sets in motion a slider 9 mounted on the stitch 7.

During the reciprocating movement of the slider 9 fixed on its front wall, the rod 8 destroys the interwell ridges (or pillars) of the angle.

In this way, the interwell well ridges from the pillars of the coal are expanded in all cases, regardless of the ratio of the drill bit diameter and the center-to-center spindle distance of the rotary machine of the buroshka machine, which makes it possible to use one of its standard size with drill crowns of different diameters and thereby increase the efficiency of application of the known executive body. Due to the fact that the connecting rod 10 is connected with the slider 9 and the sleeve 1I by the spatial hinges 14 and 15, cases of deformation of these parts with the relative movement of the branches of the screw sections are excluded.

Claims (3)

I. EXECUTIVE BODY OF THE WOODEN MACHINE, including cutting crowns, conveying screws with support lamps connected by a coupler, a movable rod fixed between the lamps to break off the inter-bore ridges, and a rod drive made in the form of a connecting rod connected by an eccentric crank shaft with augers, characterized in that, in order to increase the productivity of a screw-screw machine by providing the possibility of using one size of a movable rod, regardless of In the center distance of the cutting crowns, the executive body is equipped with a slider that is mounted on the screed, rigidly connected to the movable rod and connected to the connecting rod by means of a spatial hinge. 2. The executive body according to claim 1, characterized in that the movable rod is made in the form of two trapeziums, symmetrically attached to the slider with smaller bases. 3. The executive body according to claim 1, characterized in that the connecting rod is connected to the eccentric sleeve by means of a spatial hinge.
