Description

GERMAN

The more and more used planes for the extraction of coal in mining Operated, especially in connection with face conveyors, on which the planes are guided and in alternation Direction to be pulled back and forth, have proven themselves in soft and medium-strength charcoal. As long as the pressure of the cutting edges of the plane against the coal face is not too great and the weight of the planer and, if applicable, the conveyor bearing thereon is sufficient to support the The force components generated by the contact pressure do not give the opportunity to turn the planer off in its direction, especially to prevent the plane from climbing or lying down is running, proper operation is guaranteed. Since usually with not too hard coal that When lying down is harder than the coal itself, all that is needed is a force on the coal plane, which takes him after the lying down urges, in most cases, to keep him close to the surface at all times. To do this with To achieve safety, it is sufficient to move the cutter carrier of the plane at an angle to the lying person to arrange standing pin rotatable. This has the consequence that the one lying in front in the direction of movement Do not only cut against the coal face, but also against the lying surface.

In the meantime it has also been shown that it is possible to cut even very hard coal with a suitable planer to win in. It turned out, however, that the mentioned pivotability of the cutter carrier alone not yet sufficient to guide the plane so perfectly in the coal that it deviates from the hanging wall or lying down is avoided. This disadvantage occurs in particular in the case of wavy reclining in Wells and saddles of storage in appearance. In addition, with hard coal, what is lying on it is often softer when the coal itself is, it no longer seemed to be useful under such conditions.

Although it has already been proposed to produce the plane from parts arranged in layers, their individual parting lines at different angles run diagonally to the coal face and one or another layer of the plane can be moved from or after the coal face. But how through Tests could be determined, such a device is sufficient in connection with the pivotability of the plane is not enough to ensure that it is safe and flawless under the conditions described To give leadership in coal.

It has also been proposed a plane-like extraction device in which on the Machine body on the face and cantilevering knives are attached to the coal face, the down to Coal plow guided by a conveyor with planing tool pivotable about an axis

Joints that are right to the joint can be swiveled. When planing, the knives are spring loaded sliding along the lying and hanging walls. Only if these mountain strata are sufficiently hard, the charcoal on horizontal or hanging walls can peel off in this way can be achieved. In the case of soft mountains, on the other hand, there is a risk of the plane getting lost.

According to the invention, the planer is attached to the conveyor in its longitudinal direction by a running, approximately curved slide rail, so that an automatic one according to the curve Adjustment of the planing tool which can be pivoted about an axis running parallel to the conveyor is effected. By suitable training or setting of the curve can therefore be achieved that the Always plan at the optimum height at every point on the face, either directly on the lying surface or more or less above it, peeling, is moved along the coal face. Even so, it becomes an undesirable Deviation downwards or upwards is prevented. Setting or adjusting the curve can be effected by hand or mechanically by means of screws, thumbs, eccentrics and the like will.

An exemplary embodiment of the invention is shown in the drawing.

The planer 1 is guided laterally on the conveyor 2. The guidance takes place essentially through a The floor plate reaching under the conveyor 2, to which the planer 1 is connected by the joint 4, the pivot pin of which runs parallel to the longitudinal direction of the conveyor 2. An additional tour of the Planing is done by the curved slide rail S. By appropriate training or setting the same can be achieved that the planing cut on the coal face 6 either directly on the lying

the 7 or any other suitable place between the lying 7 and the hanging wall 8 is performed so that With the least effort, the coal over the entire thickness of the seam is as free as possible from impurities is won.
