Abstract

The utility model relates to mining machines. The technical result is the possibility of drilling on the move and the regulation of the distance between the holes within the possible drilling zones. The mining machine includes a running gear, a conveyor, an executive body, two fenders located in the lower and upper parts, a boring and anchoring unit. The drilling-anchoring unit consists of a spacer frame, the legs of which are placed in the gaps between the conveyor and the executive body, and the guides with the drilling-anchoring heads, hinged on the frame racks. Moreover, the spacer frame is pivotally mounted on hydraulic cylinders fixed on the conveyor or the executive body, providing spacer and retention of the frame with guides during the movement of the combine. The axes of rotation of the guides are directed along the movement of the combine to the face. 2 ill.

Description

The field of technology to which the utility model belongs.

The utility model relates to the mining industry, namely to continuous miners, and is intended for mining in underground mining.

State of the art

A known selective excavation machine (patent No. MX2012005440A), including a frame, a cutting device on a rotary arm and a drilling and anchoring unit located on the frame.

The disadvantage of this design is the impossibility of the drilling rig to work on the move and the presence of only one drilling rig.

Also known tunneling complex (AS No. 617592), containing a tunneling machine on caterpillars with a working body, a loader with a conveyor and a fastener. The fastener consists of a spacer beam, spacer cylinders with support skis and drilling tools mounted on manipulators on both sides of the combine. This device is taken as a prototype.

The disadvantage of the prototype, despite the articulated manipulators with a spacer beam, is also the lack of the possibility of drilling on the move and a limited drilling area - a fixed distance between the holes.

Disclosure of utility model.

The technical result of this utility model is the possibility of drilling on the move and the regulation of the distance between holes within the possible drilling zones.

This is achieved by the fact that the drilling-anchoring block consists of a spacer frame, the racks of which are placed in the gaps between the conveyor and the executive body, and the guides with the drilling-anchoring heads, pivotally mounted on the frame posts, and the spacer frame is pivotally mounted on hydraulic cylinders mounted on the conveyor or an executive body, and the axis of rotation of the guides is directed along the movement of the combine to the face.

Comparison of the proposed mining machine with the prototype allows us to conclude that the latter does not have features similar to the essential distinguishing features of the claimed utility model.

Also, the utility model does not follow explicitly from the prior art, so the authors believe that the object is new. Since with the elimination of such a technical solution as a spacer frame pivotally mounted on hydraulic cylinders mounted on a conveyor or an executive body, drilling on the move is impossible, and with the exclusion of an improvement in the form of a hinged fastening of the guides on the racks of the spacer frame, the rotation axes of which are directed along the movement of the combine on the bottom hole will not be provided with adjustment of the distance between the holes within the possible drilling zones, and, consequently, the technical result will disappear.

Description of drawings

The essence of the utility model is illustrated by graphic materials, which show:

Fig. 1 - mining machine, side view;

Fig. 2 - drilling anchor block, cross section.

A mining machine, including a running gear (1), a conveyor (2), an executive body (3), two fenders (4), a boring and anchoring block (5). The boring-and-anchoring block (5) consists of a spacer frame (6), the rack (7) of which is placed in the gaps "B" between the conveyor (2) and the executive body (3) and guides (9) with the boring-and-anchoring heads (10) , hinged on the racks (7), and the spacer frame (6) is hinged on the hydraulic cylinders (8) mounted on the conveyor (2) or the executive body (3).

The utility model works as follows. The mining machine with the help of the running gear 1 (Fig. 1) moves in the direction of the face, destroying the rock mass with the executive body 3 (Fig. 1) and forming the soil and roof with the fenders 4 (Fig. 1), the rock mass is shipped by the conveyor 2 (Fig. one). At the same time, drilling and anchoring is carried out with a drilling and anchoring block 5 (Fig. 1), by spreading the expansion frame 6 (Fig. 2) with hydraulic cylinders 8 (Fig. 1) into the roof, while the guides 9 (Fig. 2) with drilling and anchoring heads 10 (Fig. 2) are set to the required distance between the holes in the areas of possible drilling, turning around the axis of rotation, for example, hydraulic cylinders 11 (Fig. 2). Hydraulic cylinders 8 (Fig. 1) provide compression of the spacer frame 6 (Fig. 2) into the roof when the combine moves at a distance "B" from the beginning to the end of drilling and anchoring.

It should be noted that the given configuration of the mining machine and its elements are a special case and can be performed differently, the very possibilities that such a configuration gives and which, nevertheless, can be achieved by a number of other design features, are essential. The mechanisms for adjusting the movement of the guides can be made in different ways, for example, in the form of hydraulic cylinders that allow you to deflect the guides to the desired position.

Also, for the claimed mining machine in the form as it is described in the claims of the utility model, there is the possibility of manufacturing and using means and methods known before the filing date of the application.

The claimed utility model can be widely used in the mining industry for rock excavations, in particular continuous roadheaders used in underground mining.

Claims (1)

Mining machine, including a running gear, a conveyor, an executive body, two fenders located in the lower and upper parts, respectively, and a drill-and-anchor block, characterized in that the drill-and-anchor block consists of a spacer frame, the racks of which are placed in the gaps between the conveyor and the executive body, and guides with boring and anchoring heads, hinged on the racks of the frame, and the spacer frame is hinged on hydraulic cylinders fixed on the conveyor or the executive body, providing expansion and retention of the frame with guides during the movement of the combine, and the axes of rotation of the guides are directed along movement of the combine to the slaughter.
