Abstract

The invention relates to mining. The goal is to increase the stability of the combine in the unformed slaughter. The executive body includes a four-beam crosspiece (K) 1, a drill 3 with a drill 4. Cutters 5 and 7 with tool holders 6, 8 rays 2 and a drill 3 in zone 11 are pulled out of the maximum approach to the body K 1 along the organ axis. As the radial distance from the zone 11 of maximum approaching is reached, the cutters are located with understatement toward the body K 1. Regardless of the initial shape of the working tool, the tool body cuts into the array of the zone 11 of maximum approach of the cutters 5, 7. As a result, in an unformed bottomhole 3 array was equilibrated drill reluctance torque K full burial 1. When an array central portion slaughtering treated cutters 9 on the toolholder 10 x borer.

Description

The invention relates to mining l. It can be used in roadheaders.

The purpose of the invention is to increase the stability of the combine in the unformed slaughter,

FIG. 1 schematically shows the executive body; FIG. 2 is a view A of FIG. one.

The executive body contains a crosspiece 1 with four beams 2, coaxially located in front of the crosspiece of a drill 3 with a borer 4. On the beams 2 of the crosspiece 1 around the drill 3 there are cutters 5 by means of tool holders 6. On a storm 3 there are cutters 7 with tool holders 8, and indent A - incisors 9 with tool holders 10. The executive unit also contains a drive for rotating the cross and the drill in the opposite direction relative to each other (not shown), made in the form of a motor with mechanical transmission. Cutters 5 and 7 with toolholders 6 and 8 rays

2 and the drill 3 in zone 11 of the maximum alignment are expelled along the axis of the organ in the direction opposite to the body of the cross 1, and as they radially move away from the zone 11 t (the axial approximation is located with an understatement towards the body of the cross 1).

The executive body works as follows.

In the process of working the executive upratn drive rotates the crosspiece 1 and the drill

3c with a driller 4 in opposite directions relative to each other, as shown in FIG. 2, In the course of the tunneling miner, the body is set on the face to be slaughtered. However, regardless of the original

Claims (1)

the body forms is cut into the array by zone 11 of maximum approach of the incisors 5 and 7 on beams 2 and storm 3. As a result, in an unformed bottom, the reactive moment from interacting with the array of drill 3 is balanced by the reactive moment of the cross 1. As the array deepens into the array, the number of incisors 5 and 7 on the tool holders 6 and 8, interacting with the array, increase, and the said reaction moments increase proportionally. With full penetration into the massif, the central part of the bottom is machined by the cutters 9 on the tool holders 10 of the borer 4. The shape of the executive organ balances the reactive torques from the interaction with the face in the unformed bottom, increases the stability of the combine during this period, transverse vibration decreases and does not require preparation of the slab in the form of the executive body. The invention of the Executive body of the tunnel a full section mining machine, including a four-beam cross with tides on the beams located around the drill with a burr, cutters with tool holders fixed on the downhole face surfaces of the drill and tides, driving the cross and the drill in opposite directions, different In order to increase stability in the operation of the combine in the unformed bottomhole, the end surfaces of the drill and tides are made with radial inclinations one from the other in the direction opposite to the bottomhole.
