Изобретение относитс к горной промышленности -и предназначено, в частности, дл механической зачистки рудной мелочи с почвы отработанных блоков, камер и т.д. при подземной разработке месторождений полезных ископаемых.The invention relates to the mining industry - and is intended, in particular, for the mechanical stripping of ore fines from the soil of waste blocks, chambers, etc. in underground mining of mineral deposits.

Известен скрепер, содержащий боковые стенки, рабочий орган, включенный в виде набора секций, поперечину, установленную с возможностью перемещени в стенках, и т говый канат 1.A scraper is known, comprising side walls, a working member included as a set of sections, a cross-member mounted for movement in the walls, and a haul rope 1.

Недостатком этого скрепера вл етс уменьшение объема скрепера и затруднение его заполнени вследствие наличи перемещающейс внутри него поперечины, а также ухудшение проходимости и возможность поломки отдельных секций.The disadvantage of this scraper is a reduction in the volume of the scraper and the difficulty of filling it due to the presence of a cross member moving inside it, as well as the deterioration of the permeability and the possibility of breakage of individual sections.

Известен также скрепер, включающий заднюю и боковые стенки, рабочий орган, выполненный в виде набора отдельных секций с выступами, поперечину дл подъема секций, расположенную .под выступами, и т говый канат, прилем поперечина дл подъема секций выполнена в виде поворотной лопасти с рычагами, закрепленными на ее концах и установлена между задней стенкой корпуса и рабочим органом под выступами секций 2,Also known scraper, including rear and side walls, the working body, made as a set of separate sections with protrusions, a crossbar for raising sections, located under the protrusions, and a haul rope, a crossbar for raising sections made in the form of a rotary blade with levers, mounted on its ends and installed between the rear wall of the housing and the working body under the projections of sections 2,

Недостатком известной конструкции скрепера вл етс сравнительно низка его производительность , ввиду того, что часть объема скрепера (18-20%), заключенного между секци ми рабочего органа и задней стенкой , не заполн етс рудой при рабочем ходе скрепера.A disadvantage of the known scraper design is its relatively low productivity, due to the fact that a part of the scraper volume (18-20%), enclosed between the sections of the working body and the rear wall, is not filled with ore during the working stroke of the scraper.

Целью изобретени вл етс повышение The aim of the invention is to increase

10 производительности скрепера.10 performance scraper.

Поставленна .цель достигаетс тем, что в скрепере, включающем заднюю и боковые стенки, рабочий орган, выполненный в виде набора отдельных секций с выступами, поперечину дл подъема секций, расположенную The goal is achieved by the fact that in the scraper, including the back and side walls, the working body, made as a set of separate sections with protrusions, is a cross member for raising sections, located

15 под выступами, и т говый канат, задн стен ка выполнена с вертикальными прорез ми, в которых размещены выступы секций рабочего органа, снабжённого эластичными перекрывающими элементами, а поперечина 15 under the protrusions, and the traction rope, the rear wall is made with vertical slits, in which the protrusions of the sections of the working body with elastic overlapping elements are placed, and the cross member

20 is mounted so that it is movable from the outside of the side walls while the scraper has a cross member movement restrictor located in its lower part. FIG. 1 shows a scraper, side view; in fig. 2 is the same, top view; in fig. 3 section aa in FIG. 2; in fig. 4 is a view of B (parts 1.6, 1.4) in FIG. 2. The scraper consists of a back wall 1, two side walls 2, a carrier 3, a working body, which is a set of separate L-shaped sections 4, which are freely fitted at one end on a common axis 5. The back wall of the scraper, which are fixed at one end common axis 5. The rear wall of the scraper has vertical slots 6 in which the projections 7 of the working body sections are placed, provided with elastic (for example rubber) covering elements 8. The length and width of the covering elements 8 are received within the limits providing vertical cut-outs of the rear wall when lowering the sections to the lowest position, thereby preventing ore fines from falling into the slots, and the elasticity of the elements allows the scraper to maintain permeability in the block with a small height of the cleaning space. On the outer side of the side and rear walls of the scraper, under the protrusions of the sections, a cross bar is installed, made in the form of a bracket 9, movably fixed on the outer side of the side walls 2. At both ends of the bracket, the arms 10 are rigidly fixed, which are connected to the blank 11 and working 12 branches. The working branch of the rope is preliminarily freely passed through the guides 13. The length of the vertical slits of the rear wall is received within, ensuring, on the one hand, the rotation of the L-shaped sections by the pivot bracket to the upper edges of the notches, and on the other hand, by allowing the l-shaped sections to drop down a certain amount. On the outer side, on the back and side walls of the scraper, in the lower part of the scraper, there is a limiter 14 for moving the cross member, which also serves to protect it from damage during operation of the scraper. The limiter is made in the form of a metal strip of triangular cross section rigidly fixed on the back and side walls of the scraper. The scraper works as follows. When the scraper is in operation, the clamp 9 is lowered to the lowest position by the levers 10 under the tension of the working branch of the 12th rope line to the limiter 14. Under the action of its own weight, the L-shaped sections are lowered into the excavations of the soil, the ore fines are captured and removed. When the scraper is idling, the clamp 9 by means of the levers 10, under the tension of the idler branch of the 11th pull rope, rises to its highest position, lifts the L-shaped sections and presses them to the upper edge of the vertical cuts of the rear wall, while the upper edge of the wall 1 protrudes elastic overlapping elements 8, which, when meshed over the irregularities of the roof, are smoothly deflected, ensuring the passage of the scraper. The proposed design allows a scraper to increase productivity by 20% by increasing its capacity. Claims of the Scraper, including rear and side walls, a working body made as a set of separate sections with protrusions, a cross member for raising sections, located under the protrusions, and a haul rope, characterized in that in order to increase the performance of the scraper, the rear wall is made with vertical slits, in which the protrusions of the sections of the working member are placed, provided with elastic overlapping elements, and the cross member is mounted for movement from the outer side of the side walls, while clamping p has a movement limiter cross member disposed at a lower portion thereof.
