Abstract

A DEVICE FOR THE EXTRACT OF A PLANE OF PLAINS OF THE USEFUL FOSSIBLE, including a harvester with a swept executive body and a loading unit, made in the form of an inclined receiving table with a toe and scooping paws, characterized in that, in order to reduce losses and dissipate the extracted mineral, it can be used by the use of a non-hazardous mineral and it also has a suitable item, and it can be used by the use of a non-stop item, and it also has to be used by the object. prikregSheny. guide bars and on its toe there are two pairs of rollers, one of which is fixed on the axis of the guide bars, and the other is fixed above the guide bars, and under the receiving table there is a sliding tray with fixed deflectors on it installed with the possibility of moving along the guide bars and turning around the specified pairs of rollers.

Description

The invention relates to the mining industry and can be used in the combined processing of powerful flat seams of minerals of complex structure with a well-resistant top layer, mainly potash.

The purpose of the invention is to reduce the loss and dilution of the mineral to be extracted.

FIG. 1 shows the loading device of the combine in the working position, top view; in fig. 2 - the same, with the tray injected; in fig. 3 - tray extension and rotation; in FIG. 4, section A-A in FIG. 2; Fig. 5 shows a calculation scheme for determining the distance between the guide rail and the guide roller, which is necessary for turning the sliding tray; in fig. 6 is a diagram of the excavation of the lower layer of the mineral layer; figure 7 - the collapse of the rock interbed; in fig. 8 - excavation of the upper mineral layer.

The device consists of a receiving, table 1, hydraulic cylinder 2, guides. bars 3, slide 4, bonded to tray 5, deflecting stops 6, support rollers 7, guide rollers 8, stoppers 9, and side walls 10 of tray 5.

The device works as follows.

Before excavating the top layer 11 of the mineral, the receiving table 1 is lifted. Then, the hydraulic cylinders 2 of the combine 1 2 from under the receiving table 1 along the guide bars m 3 on the slide 4 pull the tray 5 and, at the time of the run of the slide 4 from the guide bars 3, the deflecting abutment 6 rests on the support rollers 7. Under the action of the pressure force of the hydraulic cylinder 2, the movable chute rotates around the guide rollers 8, which are mounted on the same axis with the guide rods at a distance ensuring the rotation of the sliding chute and l emoe the expression

where S is the distance between the guide bar and the guide roller, which ensures the rotation of the tray;

E is the projection of the distance from the heading to the support rollers in the direction of upward movement of the tray;

L is the thickness of the deflector; h is the distance from the support roller to the guide rail; oi is the angle between the deflecting abutment and the upward direction of the tray;

I is the diameter of the guide roller;

02 is the diameter of the support roller. The distance between the guide bar 3 and the guide roller 8 ensures that the sliding tray rotates at the moment of its exit from the guide bars.

The rotation occurs until the angle of inclination of the tray 5 to the horizontal approaches the angle of repose of the recovered mineral. Further rotation of the tray 5 is limited by the stoppers 9 installed in the upper part of the deflecting lugs 6. After the sliding tray 5 is brought into its working position, the receiving table 1 is lowered and I proceed to the excavation of the upper layer 11. At the same time, the mineral resource is beaten off from the upper layer 11 to the tray 5 and it is transported by gravity to the receiving table 1, with the rowing legs loaded onto the material handler and further to the delivery vehicles.

To prevent repatriation of the recovered mineral, side walls 10 are attached to the tray 5. After the upper layer 11 is removed, the loading member is reset, for which the receiving table 1 is lifted and the sliding tray 5 is pushed under the receiving table 1. Then the receiving table 1 is lowered and The harvester is ready to crush the rock layer when the loading body is not working.

The method consists in excavation by the combine 12 of the lower layer of the mineral 13, the collapse of the rock interrogation 14 and the excavation of the upper layer of the mineral 11 11. The collapse of the rock intercalation 14 and the excavation of the upper layer 11 are conducted in succession. No more than the length of the harvester takes in, because of the need to ensure the safety of the working conditions of the driver of the combine, which, when the rock spill breaks down and dredging the upper weakly resistant upper layer, is located under stable overlying rocks.
