They are devices for loading coal known, which consists of a Qüerfördermittel and a exist to this parallel bar, which rises like a ramp from the lying down and back and forth is moved forward. With the help of his lying down located cutting teeth, this beam cuts a slot in the working face, in which it by the return movement of the cross conveyor together with a downstream, between him and the side wall of the cross conveyor cherishing device occurs. The device is in a vertical position Direction hydraulically adjustable and moves up and down. In doing so, she expands the slot until that Qüerfördermittel can enter this and so gets under the loosening coal.

It has already been proposed clearing devices that led to a relocatable face conveyor and of a mining machine or a reel. These clearing devices do it Between the face conveying means and the coal face located pile by means of the lying to the face conveying means top edge rising surfaces and hand it over to the face conveyor. Because this clearing device has a limited length and is therefore for the pile task when moving in the longitudinal direction of the face always in the one in the direction must be located on the coal face moving section of the face conveyor, it is from a Operator controls and performs a reciprocating motion along the length of the face.

The main patent relates to a sliding face conveyor made of directly one behind the other, articulated interconnected members of an existing clearing device. The latter is supposed to loosen up any debris between the face conveyor and the coal face and the face conveyor in cooperation with the taking place under the influence of the rear cylinder, on the Bring the working face backward. The links consist of individual plates that are attached to a pulling element, which preferably consists of a round link chain, side by side or as Groups of members are attached. With this clearing device you can work on the entire length of the face at the same time clear and therefore also the face conveyor along its entire length at the same time or also the Following the extraction machine in one continuous move. However, the disadvantage is the high Weight of the chain strand that runs back empty and also has links or groups of links.

To remedy this and the structural and procedure for the operation of a relocatable Face conveyor guided clearing device

The aim of the invention is to reduce the expenditure in terms of weight for the clearing device.

The inventive solution to this problem is characterized in that the members or the Groups of limbs only moved back and forth with a relatively small deflection (amplitude) will. As a result, you only need the working strand of the endless pulling organ with links or limbs. To occupy groups of members in order to achieve the desired clearing effect, and thereby reduced the weight and also the structural complexity of the device is considerable. Instead of an endless one The device can also be pulled over the length of the face conveyor with a single pulling element Extending section of this pulling organ get by if you have one at both ends Provides drive.

If one occupies the working stretch of the pulling organ only with individual ones, at more or less large intervals If the limbs are distant from one another, the relatively short back and forth movement must be Movement of the groups of members from a distance that corresponds at least to the distance between the groups of members. and moving motion to be superimposed in order to absorb the pile over the entire length of the face can.

In the case of scraper systems, it is known to have several scraper boxes that are spaced apart from one another Ropes are attached, pulled back and forth by two reels on the coal pile, the one of each Scraper box distance to be covered is a few meters greater than their mutual distance.

Claims (1)

The pulling element can be driven pneumatically or hydraulically with the aid of pressure cylinders. However, it is also possible to use swivel drives or other drives suitable for this purpose. - Patent claims: 1. Procedure for the operation of a moveable face conveyor-guided clearing device, which consists of directly one behind the other, articulated links are made between the face conveyor and loosen the pile of debris located in the coal face and the face conveyor in cooperation with the under influence ;; of the return cylinder taking place, return movement directed towards the working face and on an endless traction element, preferably a round link chain, side by side or as Link groups are attached, according to patent> 1.222005 / - ^ .dad.uxch-. marked, that the members or groups of members only go back and forth with a relatively small deflection be moved. • 2. The method according to claim 1, in which; the The working line of the endless traction organ is occupied by individual groups of members, characterized in that that the relatively short to-and-fro movement of the limb groups of a reciprocating movement that corresponds at least to the distance between the groups of links is superimposed.
