The main patent relates to an extraction and conveying device for short-front mining, which with a transversely displaceable, extending over the length of the front, designed as a guide support Machine frame or frame is provided for longitudinally moved tearing tools, which an in Direction to the end of the beam discharging, in particular assigned additional short-front conveying means is.

The main patent is characterized in that the machine frame is composed of floor boxes lower guide beam and an upper guide beam composed of roof boxes possesses and both guide supports by one arranged in their longitudinal center plane Row of support elements, in particular hydraulic rams, are spaced, with under Inclination of the roof boxes of the upper guide beam facing away from the mining joint Side parts of these roof boxes can be coupled with side parts of the floor boxes by means of short locking bodies are.

According to a further feature of the main patent, the guide supports are in the longitudinal direction Central plane formed by attached profile iron beams with a strong longitudinal rib are provided, in which bearings are provided for the articulated support of the support elements are. Further features are aimed at the fact that the longitudinal edges of the floor boxes and the roof boxes are provided with guide rails or guide channels for the tearing tools. On the Floor boxes are still on both sides of the central longitudinal rib, between this and the outer guide rails or guide channels, conveyor troughs arranged and fastened.

A device of this type can be used without difficulty forward or Used in reverse and in a simple manner to the required operating position of the individual Components are prepared.

The invention relates to a further embodiment of the device according to the main patent and is characterized in that the tearing tool guide rails assigned to the long sides of the flat bottom boxes are attached to the bottom plate of the bottom box and can be pivoted together with the bottom box, the bottom box each on the axis opposite the pivot axis Long side lifting elements, e.g. B. screw spindles are assigned. and. that in the middle of the soil-extraction and conveying device for short-front mining

boxes provided supports in recesses of the floor boxes mounted vertically displaceably and with are vertically displaceable sliding shoes on the face sole can be supported in relation to the floor box.

It is the type of construction according to the invention

ao about an appropriate training for setting and regulating the cutting depth of the ripping tools. The guide rails for the ripping tools can be securely attached to the side areas of the floor boxes, and the swiveling and setting of the inclined position of the ripping tools are carried out on a particularly long lever arm. At the same time the ^r floors boxes ¹ is formed a rearwardly opening slot at each other, moving on which stones or the apparatus came materials.

Another designation feature is that that the supports in the sliding shoes in radial circumferential areas, at a distance from Base point, are pivotably mounted against spring-like return elements. This storage enables the supports, even when the floor boxes are raised, is a useful tool for heavier roof loads resilient evasion and thus contributes to increasing the stability and operational safety of the device.

The device according to the invention is further characterized in that the lifting elements their lower end with a lever-like design, preferably on the base plate of the floor boxes articulated straightening runners are coupled. These straightening runners not only secure underneath the floor boxes the wedge-shaped opening gap, but also facilitate when pressing the device against the excavation thrust the sliding movement on the lying person.

According to a special feature of the invention, the lifting elements are in one between the conveyor side wall and the guide rails provided
