Abstract

The invention relates to equipment for mountain production. The purpose of the invention is to increase the rate of penetration of workings of various heights of arch form 1 to ensure smooth contours. The heading machine includes self-propelled gaassi associated with the; frame 3, the main boom 10 and the additional boom (DS) 12 with the bogie bodies 11 and 13. The frame 3 is connected to the platform 15 ryuch 13 / fy ////// /// П W 1721 20 15 M //// U // u ///// //////////// / //// // {/////. gami (P) 17.18.

Fi.g

The invention relates to mining, and more specifically to selective action harvesters for drilling horizontal and low-angle workings in rocks of medium strength,

The purpose of the invention is to increase the rate of penetration of workings of various heights of the arched shape, ensuring smooth contours.

FIGS. 1 and 2 show a combine, respectively, in a side and top view in FIG. 3 — a combine, rear view.

The proposed combine is arranged blowing.

On the self-propelled chassis 1 with outriggers 2 and frame 3, there is a sock-feeder 4 with conveyors 5 and 6, and the tagok is turning the turret 7 with hydraulic cylinders 8 of rotation. The turret 7 is articulated with the help of hydraulic cylinders 9 for lifting the main boom 10 with the breaker body P, is fixed. 13 in the vertical plane, and the other end of the additional boom 12 is harned on the platform 15 and connected with it by the hydraulic cylinder 16 turning the additional boom in the vertical plane. The platform 15 is connected to the frame 3 by means of levers 17 and 18, which are parallel to each other with an inclination in the direction opposite to the bottom hole, and can make a reciprocating movement along the axis of the combine through the feed hydraulic cylinder 19. The platform 15 is provided with a drive 20 rotating the shaft 21, on the end of which the L-shaped holder 22 is fixed, on one end of which an additional boom 12 is hinged, and on the other - a hydraulic cylinder 16 of turning the additional boom in a vertical plane. Figs, 2 and 3 are marked: 23 - overload conveyor (loading crane); 24 - transport vehicles, for example, the composition of trolleys; 25 - rail track (cola); 26 and 27 - possible production contours

The combine works as follows.

With the help of the chassis, the combine supplies the face and clears out outrigger 2. Under the loading crane 23 serves

the composition of the trolleys 24 and include the fender body 11 on the boom 10, moving it through the hydraulic cylinders 9 and 8 along the slaughterhouse.

DGG imparting the desired shape with the smoothness of the walls of the excavation and the required configuration using the hydraulic cylinder 19 and the levers 17 and 18 set the platform 15 to the desired height, for example, in the center of curvature of the roof of the excavation. Then using the hydraulic cylinders turn 16 and 14, an additional fender body 13 is installed at the required height and put it into operation.

Forced by turning the drive 20, shaft 21, the roof and the sides of the excavated workings are processed to obtain a smooth contour in the required dimensions. The beaten-off rock is loaded with a sock-feeder 4 on conveyors 5 and 6 and then re-loaded by a loading truck 23 into vehicles 24, for example, the composition of trolleys mounted on track 25 under a loading device 23.

If it is necessary to change the working height with the help of a hydraulic cylinder 19, lower or raise the platform 15, on which the boom 12 is fixed, and also change the angles of the boom through the hydraulic cylinders 16 and 14.

In the absence of the need for careful processing of the arch of development, the boom 12 with the fender body is used to destroy bottom rocks, which leads to a higher penetration rate.
