Abstract

Use: for mechanized sinking of horizontal and weakly inclined openings. The invention: the combine contains a working body, the main and additional drill rigs. The scraper pivoting in the vertical plane is installed on the additional gate. . The main stage rotates and axial reciprocating movement of the working body. In the direct course, scrapers transport the destroyed rock along the mine. During the return stroke, the scrapers turn and the rock is not transported 5 sludge.

Description

The invention relates to mining and can be used in mechanized, penetration of horizontal and weakly inclined workings, as well as in mining enterprises in the underground mining of minerals from thin layers and vein deposits.

The purpose of the invention is to increase efficiency by improving the cleaning of wells from broken rock.

Figure 1 shows the harvester at the time of sinking production; figure 2 - section aa in figure 1; on fig.Z - section bb in fig, 1; figure 4 is a view In figure 1; figure 5 - node I in figure 1.

The drilling machine contains frame 1, rotator 2, feeding cylinders 3 with oil station, drilling station 4, working body 5, guide 6, t gu 7 with scraper 8, additional oil station 9 and hydraulic cylinder 10.

The guide 6 consists of sections and is attached to the working body 5 with the possibility of rotation.

In the guide 6, a ha is mounted 7 with the possibility of axial movement. T ha 7 consists of sections to which the scrapers 8 are fastened with the possibility of limited rotation in the vertical plane.

The combine works as follows.

The frame 1 of the combine and the frame 11 of the additional oil station 9 are fixed in the main 12 and auxiliary 13 mines and begin to drill the advanced well 14, while the torque from the rotator 2 and the force from the feed cylinders 3 is transmitted through the drill bit 4 to the forward bit. After the bit reaches the auxiliary output 13, instead of it, the working body 5 is hung on the drill stand 4, and the output is drilled 15. After drilling 15 is drilled, a section 6 with a connecting section 7 is attached to the working body, one end of which is attached to an additional 1U hydraulic cylinder. But as far as penetration of the output 15 is produced, the sections of the guide 6 and 7 are increased.

With the help of an additional hydraulic cylinder, 10 tons ha 7 with scrapers 8 reciprocates. When moving the scrapers 8 in the direction of auxiliary excavation 13 (working stroke), the destruction products 16 are transported; during the return stroke, during which the scrapers can turn in a vertical plane, no degradation products are transported. Since the stroke of the additional hydraulic cylinder 10 is greater than the distance between adjacent scrapers 8. this ensures the maximum

possible performance of transportation of products of destruction.

After the excavation of the excavation, the sections of the guide and the tie rod are dismantled.
