Abstract

The invention relates to the mining industry. The purpose of the invention is to increase the productivity during the excavation of complex formations with rock formation. The harvester consists of a hull (K) 1 with skis and grippers for connecting to the bottomhole conveyor with screws (Ø) 2 and 3 for excavating the mineral and cutting drum (RB) 9 with a vertical axis of rotation for excavating the rock formation. The latter is installed with the engine 11 with the possibility of adjusting the height of the additional support frame (RR) 14, pivotally connected to K 1. When turning relative to the RR, 14 RB 9 occupies an advanced position of W 2 and 3 to the side of the bottom and is installed behind them during the development . In this case, the loading plate 17 is installed behind the latter in the direction of movement W 3 and is rotatable 180 ° around W 3. In the operating position, W 2 is above, W 3-below, RB 9 is hacked with an oblique approach when turning to the side . Destructible minerals W 2 and 3 are loaded onto the conveyor with the help of a flap 17. The rock layer is emitted by the RB 9 from the notch gap and folds on the soil. At the end of the excavation of the RB 9 with the help of the hydraulic jack 15, they pull out of the notch slot, and the flap 17 is moved 180 ° around W 3. When the combine is moved to the other side, W 3 and the flap 17 is loaded onto the conveyor, the destroyed layer is at shunting speed. At the end of the lava, the cycle repeats. 3 hp f-ly, 4 ill.

Description

The RB 9 is from the notch gap and folds on the soil. At the end of the excavation of the RB 9 by means of a hydraulic jack 15, they are pulled out from the notch gap, and the flap 17 is moved 180 ° around the Sh 3.

When the combine moves to the other side of the Sh 3 and the shield 17 loads t on the conveyor, the destroyed layers are at shunting speed. At the end of the lava, the cycle repeats. 3 hp f-ly, 4 ill.

The invention relates to mechanization for underground selective mining of minerals with the help of shearers and can be used, for example, in the conditions of the Starobinskoye potassium salt deposit, the layers of which contain in the middle part of the mineral layer of the rock.

The purpose of the invention is to increase the productivity of the combine when excavating layers of complex structure,

Figure 1 shows the scheme of the combine "top view, the position when the working stroke; figure 2 - the same., the position when the distillate; in Fig „3 - view A in Fig.1; figure 4 - view B in fig.Z.

The combine for selective excavation includes an 1S4 body, an executive body consisting of two height-adjustable cutting augers 2 and 3 driven by an electric motor 4, placed on rocking gears 5 and 6, and height-adjustable by hydraulic jacks 7 and 85, and also of the cutting drum 9, which is driven through the gearbox 10 of the electric motor t1. The cutting drum 9, the gearbox 10 and the electric motor 11 are made in the form of an actuating unit 12 (Fig. 2) connected by means of a hinge connection 13 to the support frame 14 (Fig. 3).

The rotation of the Executive unit 12 in the plane of the reservoir to be removed is carried out by a hydraulic jack 15. The support frame 14 is connected to the housing 1 by a hinge 16 (FIG. 3).

The screw 3 is equipped with a loading flip flap 17 (Fig.1,2).

Skis 18, 19, 20 (FIG. 3) and grippers 21, 22 23 (FIG. 1) are provided to connect the hull 1 and the support frame 14 to the downhole conveyor.

A hydraulic jack is provided for adjusting the roaring drum relative to the rock layer.

If necessary, a loading shield 24 can be installed behind the cutting bar 9.

The excavation of the mineral and rock layer is carried out simultaneously. For this, the actuating unit 12 is installed in the working position with the help of a hydraulic cylinder 15 (FIG. 1). The position of the cutting drum 9 relative to the rock layer is controlled by the hydraulic cylinder. The screw 2 is installed with a hydraulic cylinder 7 in the upper position. The screw 3 is lowered with a hydraulic jack 8 in the lower position. After this, the combine is reported. Movement along arrow G (Fig. 1). Augers

2 and 3, the mineral is destroyed, which is loaded on the conveyor by screw 3 and flap 17 installed behind screw 3 as the combine moves. The destructible cutting drum 9, the rock interlayer, is ejected from the notch slot and stored on the previously cleaned soil between the conveyor board and the bottom.

At the end of the excavation of the mineral and rock layer, the cutting drum 9 is pulled out of the notch slot by means of a hydraulic clamp 15, and the flap 17 is moved around the auger 3 in the 180s (FIG. 2). After that, the combine is told to move in the other direction (along the arrow In fig, 2). Auger

3 and the loading flap 17, the destroyed rock layer is loaded onto a conveyor belt for transport to the storage site. The movement of the combine is carried out at the maneuvering speed, which in conditions of potash faces is 5-6 times more than the working one.

At the end of the lava, using a known technology, a notch is cut into a new strip by an oblique approach, after which

the work cycle is repeated.
