The main patent relates to a coal plane for two peeling directions, which by in particular endless traction means can be pulled back and forth on the working joint and is slidably mounted in the planer body Has peeling tools that can be propelled by spring-loaded impact bodies, the springs and the impact body depending on the cutting resistance of the tools by the planing traction device an interposed cam wheel drive can be moved in the clamping position. The main patent identifies in that each between two oppositely arranged peeling tools or tool groups, a double impact body common to both tools is provided is clamped at both end areas by a set of springs in the plane body and in the middle part is geared coupled to the cam wheel with simultaneous tensioning of both sets of springs, wherein however, the double impactor only the tool held back by the resistance of the coal impact apply.

With this coal plow activated by the traction device, the prevailing view was initially that with regard to the cooperation of the traction means with the cam gear drive the plane body must maintain its basic position. This leads to the fact that the rear, i. H. the Grind the tools you have drawn on the excavation joint and the base. With the simple static coal planes or coal plows in which there is no pulling strand opposite the plow body Performs relative movement, it is known to either move the tool carrier on the guide bar Pivot pivotable or to be mounted in sliding guides partly longitudinally and partly transversely. With these known designs, the traction mechanism engages at the end of the guide bar. Another well-known The construction of this statically working coal plane uses a kind of disk-like tool carrier, on a vertically directed longitudinal side of the planer guide body by means of two in the Horizontal plane limited pivotable lever is mounted, which in the direction of the working face too are arranged converging. These two short levers make the cutting edges dependent of the change in the direction of movement of the coal plow either in the direction of the working face pressed or pulled to the planer guide body, which is located directly on the side wall of the Conveyor slides. Essential for these static planes is the basic training according to which is the planer guide active jerter coal planer sliding on the conveyor

body detected by the traction device and then transmitted the tensile forces to the tool carrier via the storage will.

The invention is based on the object of developing a suitable structural solution that allows also with the activated coal plows, which are controlled by the traction mechanism and which work temporarily To create possibilities for the automatic adjustment of the tools.

According to the invention this object is achieved in that the planing traction means while maintaining the its direction of pull corresponding position by the pivoting non-hindering guide channels of the Tool carrier is passed, in which the flywheel and the cam gear including Sprockets are arranged.

In this structural configuration of the activated coal plow, in contrast to the conventional type of connection of the traction means, this is now through a correspondingly wide guide channel of the pivotable tool carrier passed through. on In this way, the traction means is advantageously relocated in the vicinity of the cutting plane. The swivel range this tool carrier penetrated by the traction means does not yet lead to disruptive Influences on the transmission connection of the traction mechanism and the cam drive. Working together the traction mechanism with the sprockets of the cam drive is therefore preserved. An essential one The advantage of the invention is that this direct connection of the planing traction means relieves the articulated connections to the planer guide housing with the swiveling tool carrier stay. The planer guide housing is thus in the

In contrast to earlier designs, the tool carrier is drawn in the longitudinal direction of the conveyor taken away. Since the loads on the joint connections are small in this case, this results in the possibility of simple connections or guided tours.

In the drawing, the subject matter of the invention is illustrated by way of example.

F i g. 1 shows a coal plane in view;

F i g. 2 shows part of the coal plow according to FIG. 1 partly in view, partly in vertical longitudinal section;

F i g. 3 and 4 show the coal plow in plan view, specifically in two different exemplary embodiments.

The coal plow is shown in the FIGS. 1, 3 and 4 by means of an endless pull chain pulled back and forth along the coal face. This coal plow consists essentially of the Planer body 1, in which device parts described in more detail below for coupling the traction means are housed with the planer body and for driving the tools. The tools are arranged at both ends of the planer body 1.

The return strand 2 and also the tension strand 4 are through a channel-like recess 3 of the tool carrier 1 felt through. The traction strand 4 is arranged one behind the other via three in the planer body 1 Chain wheels 5 and 6 out. The two outer chain wheels 5 are loose on their axes rotatably arranged; they only serve to guide the chain and to increase the angle of wrap at the middle sprocket 6. On the shaft of the sprocket 6 is a serving as a tensioning wheel Cam wheel 7 attached.

The coal plane has two groups of tools (chisels or paring knife) 8, 8 'or 9, 9'. In the planer body there are several, in particular at a distance from one another arranged flywheel 12,13 arranged axially displaceable. These flywheels are mounted in spring assemblies 15 in their end regions. The flywheels transfer their balancing energy into appropriately on the tools. The balancing energy is thereby in the flywheels 12,13 generated that as a result of the rotational movement of the tensioning wheel generated with greater resistance of the tools 7, which act on this cam 10 attached to rocker arms 11 and 14, which have a limited Force axial displacement of the flywheel against the action of the spring assemblies. The ones in the Energy stored in spring assemblies is released as soon as the cam 10 of the tensioning wheel passes over the counter cam or a counter roller slides, which is assigned to the rocker arms.

The rocker arms 11 and 14 are each below their flywheel on transverse axes in the planer body stored. The upper rocker arm 14 is formed at an angle.

ι As shown in FIGS. 3 and 4 can be seen, is the from the traction means or the traction means sections 2 and; 4 · plow body 1 penetrated by an additional housing 20 assigned, which serves as a guide or guide bar, which is on the longitudinal side of the conveyor 21 supports. The additional housing has a length approximately corresponding to the plane body 1 and is in a in the drawing not shown in detail manner with the planer body in the sense of a take-away coupled.

In the embodiment according to FIG. 3 is between the additional housing 20 and the planer body 1 a sliding guide 22 is provided which lies on a sector of a circle. The planer body 1 leads to this Sector from a pivoting movement, such that, depending on the direction of pull, either the one or the other tools are in contact with the working joint and are swiveled into the operating position. the The pivoting movement is chosen so that the tools are directed towards the working face and the longwall face perform limited movement.

The guide channel 3 is dimensioned such that the planer body 1 opposite the tensioned traction means can perform sufficient pivoting and that the engagement of the traction means on the sprockets 5 and 6 is maintained. There are also stop elements 23 'at the ends of the planer body. provided, while cutouts with mating surfaces 23 are attached to the additional housing.

In the embodiment according to FIG. 4 is the planer body 1 with the additional housing by two short, differently arranged handlebars 24 connected. There are stop surfaces on the additional housing 24 'provided, through which the pivoting dimension of the handlebars and thus also the longitudinal displacement of the planer body 1 is limited. Otherwise, the overall design corresponds to this exemplary embodiment that according to FIG. 3. It is therefore dependent on the different position of the handlebars from the direction of pull one tool group in each case in the operating position, and that at the same time pivoted against the working face and against the longwall face, while the other tool group is in the rest position is withdrawn.
