Abstract

Apparatus for extracting mines with a planing-type basic body struck on both sides by a traction means, which receives pressure against the excavation by a pressure means and a tool body is slidably movably mounted on the guide body on a guide between laterally guide-limiting, adjustably mounted stops. The tool body is dismantled abbrustossseitig rooftop. Each area is equipped with extraction tools necessary for the extraction. The tool body automatically adjusts itself to one of the stops in every pulling direction and uses one of the surfaces equipped with extraction tools, while the angled part of the tool is lifted off the excavation shaft.

Description

Pressure component occupies the working face as employment, preferably 15 °. Under these conditions, all tools effectively engage the chamfer at the chamfer facing the respective pulling direction. The sliding path of the tool body on the guide on the planing body limiting on both sides stops are designed so that they slide powerless in the working position of the device, the tool body is opposite to the direction of pull at the local stop, at the abutment. However, they limit the rotational movement of the device with changing forces and prevent an ineffective employment at the excavation, in which not all extraction tools that are kept ready for it are used. By adjusting the attacks, it is possible to change the sliding path of the tool body and thus the employment of the device on the working face when required in one or both directions.

embodiment

The invention will be explained in more detail below by way of example. In the accompanying drawing mean:

Fig. 1: representation of the device in its technical means;

Fig. 2: View of the device in the working position on the mining face.

The device consists of a posted to a traction means 1 base 2, the abboustoßseitig has a rail as a guide 3, which is bounded at both ends of the body 2 by a respective stop 4. A tool body 5 is provided with a groove 6. Guide 3 and groove 6 are formed so that both brought into engagement, allow a sliding movement of the tool body 5 on the guide 3 between the stops 4 on the abboustoßseitigen surface of the base body 2. The tool body 5 has directed to the working face 8 a symmetrically beveled, roof-shaped front, which is angled on both sides 15 ° to the guide 3. Each of these surfaces is equipped in the same way with cutting tools 7.

If the device attached to a cable as traction means 1 and brought by a pressure means 10 via a pressure roller 9 with a Andruckkomponente device is brought to the excavation 8, it comes to this used. The tool body 5 adjusts itself to a stop 4, which limits the Gleitweg on the guide 3 in the direction opposite to the pulling direction, fixed, the entire device pivots so that all on the pulling direction facing beveled surface of the tool body 5 attached cutting tools 7 evenly on Attack the deconstruction 8 and perform the given extraction work. The cutting tools 7, which are mounted on the tapered surface of the tool body 5 facing away from the pulling direction, are lifted off the excavation 8 in this working position. When changing the train direction of the tool body 5 slides on the guide 3 to the stop located at the other end 4, the device pivots in the opposite direction, and so far lifted off the excavation 8 Schneidkwerkzeuge 7 are used while the previously active from the mining face 8 take off.

Claims (3)

1. Apparatus for mining extraction with a posted on both sides of a traction means hobeiförmigen body, which receives a Andruckkompomente via a centrally located pinch roller of a tensioned pressure means that pushes it areden Abbaustoß, and with a attached to the body tool body to which all for the extraction required tools or certain groups of tools are arranged, characterized in that the base body (2) abbaustoßseitig a guide (3) which is eccentrically bounded on both sides by a stop (4) that a tool body (5) with a guide member (6) on the guide (3) between the stops (4) is slidably movable, that the tool body (5) formed abboustoßseitig roof-shaped flattened and that each surface is equipped with extraction tools (7). 2. Apparatus for mining extraction according to item 1, characterized in that the roof-shaped beveled surfaces on the tool body (5) have a bend of preferably 15 ° to the course of the guide (3) on the tool body (5). 3. A device for mining extraction according to item 1, characterized in that the stops (4) on the guide (3) adjustably mounted and are designed so that, when the extraction tools (7) attack at effective working position on the mining face (8) , do not reach the working face (8). For this 1 page drawings Field of application of the invention The invention is intended for use in mining underground where recovering by not necessarily guided at the mining face of a traction device pulled along planer-like devices that are pressed by a pressure means, a tensioned rope or a chain, against the quarry, proceeds. Both the dissolution of rock from the solid dressing and the removal of the rock thus obtained are carried out. Characteristic of the known technical solutions The mechanized mining extraction of seams in longwall mining is most effectively achieved by planing, peeling, cutting or tearing extraction devices which loosen and remove the mining rock to be extracted from the rock formation. A planing-type extraction device is pulled on both sides of a traction device, a chain or a rope struck along the excavation and leads when it is mediated by the tension of a pressure medium center a pressure, the required extraction by. The respective tool body is equipped with appropriately designed and arranged extraction tools. A special design of planing bodies is to make them so that they can do extraction work in both traction directions and no Leerzüge arise. However, such devices are known only from the technical direction of the positively driven planing body. By pivoting devices, e.g. In DE-OS 2918465, such changes are effected on the hollow body, which result in a functional capability in both directions of pull. The tools required for the respective pulling direction are used, while those intended for the opposite direction lie in the shadow of the planer body. When changing the pulling direction, the pivoting takes place, in which the previously available tools are used on the excavation, while the previously used occupy a raised position from the excavation. When pulled, not forcibly guided devices, the technical condition arises that the planing body arranges in the pulling direction in switching a Andruckkomponente with a job at the excavation. It follows that the tools must be designed and arranged accordingly, especially if under these conditions a uniform mode of action in both directions is to be achieved. Object of the invention The aim of the invention is a device in such a way that it works in both directions of pull with equal effectiveness and that the tools are used in a manner in which their life increases significantly. Explanation of the essence of the invention The invention has for its object to provide a device that automatically ensures effective use of active tools on the mining face for each direction of pull, while the tools intended for the opposite direction are lifted from the excavation. According to the invention, this object is achieved in that the main body of a planing-like mining device, which is posted on both sides of a traction means and receives a pressure against the excavation head in the center of a taut pressure means facing the excavation wall has a guide which is bounded on either side by an adjustable stop , On this guide, preferably designed as a rail is, sliding between the stops, a tool body arranged, which is equipped with the tools required for the extraction. The tool body is roof-shaped. The required tools are attached to the beveled surfaces. The chamfers secure on both sides of the angle, the device in the train under the action of the center adjacent
