    The invention relates to the mining industry, in particular to a combined structure for the extraction of minerals, in particular coal in underground mining. A combined plow is known, the BkjB04aroi4Hfi are two simple plows equipped with tool holders with cutting tools and pivotally interconnected 13. The disadvantage of this combined plow lies in its low productivity, especially when excavating coals with higher cutting resistance. The closest to the technical essence and the achieved effect to the proposed is a combined plan for the extraction of minerals, including two simple planes having tool holders with cutting tools and interconnected by means of hinged joints of the fastened plank, made of rigid joints another with the possibility of bending in a vertical plane around hinge bolts 2 transverse to the direction of movement of the plow. The disadvantages of the known plow are limited Increased productivity at a given speed of movement, the complexity of application in low-thickness formations and the implementation of excavation of higher cutting resistance. The purpose of the invention is to increase the productivity at a given speed of movement and the use of plow in thin layers. This goal is achieved by the fact that in a combined plow for the extraction of minerals, mainly for the extraction of coal in underground mining, containing at least two moving plow chains along the guide, simple plows that have tool holders with cutting tools and are connected to each other by means of hinged joints made of rigid connecting plates, entering one into the other with the possibility of bending in a vertical plane around passing across the direction of movement of the strugo pivot bolts Tool holders with cutting tools in the direction of movement of the plow are installed with increasing overhang on one cutting line from one simple plow to another. In addition, the plow chain is connected to the front end in the direction of movement of the plow end of each plow. Simple strugues in the hinge area have horizontal rollers and one common vertical roller mounted on the hinge bolt, with the rollers mounted on the guide plow with working surfaces. Fig, 1 shows a combined plow with two simple strugs, view from the side of the bottom; in fig. 2 the same, a kind of reconciliation; FIG. 3 is the same, front view; Fig. 4 shows a combined plow with a portal guide, top view; Fig. 5 is the same, front view, Combined Plow 1, for the extraction of minerals, namely, coal plow for underground workings, has plow guide 2 and simple plows 3-5 with at least one tool holder 6 of the cutting tool being moved along a plow chain guide 2, to which simple pins 3-5 are connected. The plow guide 2 is attached to the sidewall 8 of the section of the chain scraper conveyor 9, the combined plow consists of two or more simple pads 3-5 connected to each other by hinges tO, the tool holders 6 of the plow 3-5 cutting tool are respectively aligned along the vertical axis 11 to the front 12 in such a way that the cutting depth T, T and Tj of the cutting tools 13 on the holders 6 increases in the direction of movement from one simple plow to another, and finally, a predetermined total depth is reached for cutting T, Due to this, the total cutting depth T is divided into separate cutting tools 13 simple plows 3-5, the Combined plow is made of two simple plows 3 and 4 of the same height, however it can also consist of a larger number of plows, for example three 3-5 simple planes, the average of 4 of which are made 3 in the form of a tower plow (not shown). The plow chain 7 is connected to the front end of a simple plow 3 or 4. The pivot joints 10 are rigidly attached to the simple pins 3 and 4 of the connecting pads 14, which are inserted one into another with the possibility of bending around in a vertical plane around that transverse to the direction of movement. the pivot bolt plow 15. The pivot joints 10 have, in the interaction zone of the connecting pads 14, a predetermined horizontal clearance S, due to which a ram effect is provided between simple strugs 3-5, if the speed of A simple struga 3 suddenly decreases. This is the case, for example, when a simple plow 3 going ahead is wedged unconsciously at face 12 or is prone to this. The following simple strugues 4 and 5 collide with the jammed strug and one against the other with a predetermined gap S between them, due to their kinetic energy, push the stuck strug 3. Then the gap S is set automatically, so that you can again achieve the push effect if the front plain stru it starts to jam. Therefore, the horizontal gap S between simple strugs is of great importance.
    Fmg, g 53 .4 Simple plows 3-5 have, in the area of the articulated joints 10, horizontal rollers 16 and one common pivot roller supported on the pivot bolt 15, moving along working surfaces 18 and 19 guides 2 plows, which serve to using simple plows 3 and 4 on the plow guide 2. In another form of implementation, simple plows 3-5 have a portal support 20 on the side of the open space, which is recommended for large structural heights of simple plows. In this case, the portals of 21 simple plows are connected with one another by spring elements 22. The latter are rigidly fixed on one portal and connected to the other portal with a horizontal gap. When performed with three simple strugami 3-5 spring elements 22 mounted on the portal 21 of the average struga 4 and combined into one or more packages of flat springs. The proposed constructive embodiment allows increasing the performance at a given speed of motion, destroying the increased resistance with each individual plow successively with a greater overall chip thickness, having a more balanced design with good soil unevenness and applying the plow in thin layers.
