BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coal plow especially provided on a scraper conveyor equipped with a truss with extraction devices arranged at an angle to each other, with the pivoted lower cutter heads disposed on the sides of the beam in vertical planes. connecting knives arranged with one another, which, when the direction of movement of the coal plow is changed, are brought to the working position in a rotational fashion. German Patent Specification No. 1,059,285 describes an embodiment of a coal plow which is guided on a rake conveyor and which is provided with mining devices disposed relative to one another and arranged at the ends of the longitudinal beam and provided with knife heads pivotable Both the cut-out devices are formed in such a way that their lower part, approximately at the height of the scraper conveyor, which is left behind, the free ends of the coal plow, is only covered by the cutter blades and the cutting blades are slightly above them, while the cutter blades are provided with disconnecting blades. that plow the middle and top of the coal pillar. Correspondingly constructed mining equipment is provided on its mutually adjacent sides in the lower part, approximately up to the upper edge of the nail conveyor, with individual disassembling knives, whereby the inclined rising pile shields are attached to these surfaces, the coal being disconnected from the corridor lifted up and loaded onto the ridge conveyor across the side profile. The living device is thus mounted so that it can be folded down when the coal plow is turned. The forward-facing mining unit moves freely with its lower blades and cutting blades in its lower part and continues in its upper part with the interconnecting knives arranged on top of each other on the coal pillar, while the lower part of the mining device is a coal-pillar vest only with disengaging knives arranged from the top to the top edge of the scraper conveyor. Above all, the action of the scissors and the scoring knives eliminates the charcoal. The plow extraction is carried out by dissolving knives, which are placed on the forward mining equipment above the scraper conveyor and on the second mining equipment only laterally adjacent the scraper conveyor.

Coal plows are also known in which the knives are arranged in groups in the direction of movement of the coal plow one above the other such that the knives of the first group form 205066 203066 in the coal pillar of only parallel grooves and the remaining coal between these grooves is distributed by knives of the following group of knives.

SUMMARY OF THE INVENTION The object of the present invention is to provide a coal plow with a plurality of, and more distally spaced, construc- tion devices formed in such a way that both home furnaces, more or less identical, are involved in the mining and loading operations and simultaneously cut the coal pillar. more or less smooth surfaces. In addition, in any direction of movement of the coal plow, all the blades that are not in the working position are to be moved away from the coal pillar so that they do not deteriorate on the surface being created and thus do not wear out inefficiently, thereby increasing energy consumption.

SUMMARY OF THE INVENTION The present invention solves the object of the present invention by providing a coal plow which comprises, on the lower cutter heads, interlocking shields and scraper blades which are formed with a molded mesh occupying the entire height of the coal plow and corresponding to the depth of cut. the depth of the cutter blades of the lower cutter head of the cutter blades of the upper cutter head.

According to a preferred embodiment of the invention, each lower blade head plow mounted pivotally has an upper knife head arranged above its opening knives by pivotably mounted knives on one side and has a scraper blade provided above the pile shield on the other side. the upper knife head and the wiper blade are connected together by a tie rod.

According to a further preferred embodiment of the invention, the pivot axis of the upper cutter head and the oscillation of the scraper blade are arranged in a downward direction to the lower cutter head. An exemplary embodiment of the invention is shown in the accompanying drawings wherein the giant. 1 is a perspective view of a coal plow in the direction of the coal pile, and FIG. 2 is a corresponding coal plow cross section in the direction of movement of the plow.

The coal plow 12 is slidably guided on the rack conveyor 11, which is located by the preload pillar 10. The plow body of the coal plow 12 is designed as a beam 13, which is supported at its ends by means of support arms 14 on the guiding lip 15 of the blade side of the scraper conveyor 11 An additional bearing of the coal plow 13 is provided by means of at least one rearwardly directed horizontal burner 16, which arms 16 extend over the entire conveyor conveyor 11 and a guide rail 18 is supported by the supports 17, which is fastened to the load side of the conveyor 11 .

The coal plow is provided on both ends with mining devices which are mounted on the two support legs 14 of the beam 13 or in front of them.

Each mining apparatus comprises, in the exemplary embodiment of the invention shown in the drawings, a pivoted lower head 19 which can perform a noticeable oscillation motion about the horizontal pin 20 at its upper end. At the lower end, the lower cutter head 19 is still guided in an arc-shaped guide 21. The pivoting movement of the lower cutter head 19 is limited by a fixed stop 22 on the left side. 23. On the lower knife heads 19 of the two coal plow extraction devices 12 there are disengagement blades 24 at the free ends of the coal plow 12. A knife 23 is also arranged below the disengagement blade group 24 and can be rotatably adjusted from the base side. In the illustrated embodiment of the coal train 12, a picking knife 27 is further provided with the cutting knife 25, which is jointly adjustable with the starter blade 25.

Shielding shields 28 are arranged on adjacent sides of the lower leg heads 19 of the two mining coal plow 12.

When the angle plow 12 travels along the coal pillar 10, the coal is mined in the lower region of the disengagement knives 24, the picking knife 27, and the scoring knife 25, approximately to the height of the scraper conveyor 11, or to the height of the guiding profile 15, the screed 18 which is on the latter, while the lower shear bar 28 of the lower cutter head 19 of the second coal plow extraction apparatus 12 is operated as a loader, especially when moving through a corridor between the coal pillar 10 and the ridge conveyor 11. The refill shield 28 lifts the corrugated coal to the entrance and extends it above the guide profile 15, but below the beam 13 from the side to the crest conveyor 11. At the same time as the reel plate 28, it detaches the remaining coal on the coal pillar 10 which remains between the scraper-shaped cutter blades. In the coal plow 12 of the present invention, the upper cutter head 19 with the cutter blades 24 and above the cutter plate 28 is further provided with an upper cutter head 29 and a cutter blade 30, which are hinged to the lower cutter head 19, for reasons of clarity of drawing. are shown the pivot axis 31 of the upper cutter head 29a oscillating axis 131 of the scraper blade 30, which downwardly extends downwardly to the lower cutter head 19 at an acute angle about which each lower cutter head 19 can be deflected parallel to coal pillar 10 from one extreme position to another extreme position. Furthermore, the upper knife head 29 and the knife 30 are joined together by a rod 32 which is connected to the upper knife head 29a on the wiper blade 30 by pivoting the pivot axles 21 and 131 respectively.

The upper cutter head 29 is provided with a plurality of interconnecting tabs 33 disposed one above the other on the free end plow 12. When the upper cutter head 29 is in the working position, the cutter blades 33 lie approximately vertically one above the other and their row is attached to the upper end of the cutter blade cutter blade group 24. The cutter blades 33 of the upper cutter head 29 move on displacement as well as the cutter blade 24 of the lower cutter head 19 and plow longitudinally on the coal pile 10, forming parallel grooves therein. A portion of the coal that is disengaged by the splitting knives 33 of the top cutter head 29 is fed to the ridge conveyor. The remainder of the coal falls off the ridge conveyor 11 and is collected in the corridor between the rake conveyor 11 and the coal pillar 10. This coal as was As mentioned above, it is captured by the reclaiming shield 28 of the second mining apparatus of the coal plow 12a being fed laterally to the ridge conveyor 11. While the opening knives 33 of the upper knife head 29 lying in front in the direction of the moving plow 12 are in the working position, the rearwardly extending scraper blade 30 is of the same lower cutter head 19 is tilted as shown in FIG. 1. This wiper blade 39 is thus in the working position, but is deflected by its pivot axis 131 from the coal pile 10 towards the pile. Therefore, as mentioned above, the retractable shield 28 of the mining device, which is in the rearward position of the coal plow 12 in the rear position, is deflected into its working position as shown in FIG. in this case, with the respective wiper blade Pt EDM Ě T CLAIMS 1.
