Description

Known coal miners working with the frame of the conveyor, as well as with the executive body in the form of shearing bar. However, these combines do not provide separate excavation of coal and rock.

A distinctive feature of the proposed combine is the separation of coal and rock packs of the reservoir during the excavation process, for which the chipping bar is rotating about a horizontal axis parallel to the bedding of the reservoir and perpendicular to the bottom of the lava, simultaneously transporting the material and coal above the conveyor.

In order to transport the material along the bar, it is provided with a tray through which the bar chain moves, equipped with scrapers-fists. Separation of coal and rock flows produces a rotary shield, mounted on the body of the combine above the main conveyor. The shield is kinematically associated with the bar and automatically closes the conveyor when the rock is dispensed.

For the convenience of transporting the combine at the bar, the base attached to the rotating block is curved at an angle of 45 ° to the plane of the bar.

FIG. 1 shows a harvester in lava; in fig. 2 is a diagram of a formation excavation by a working body operating on the principle of large cleavage; in fig. 3 - kinematic scheme of the combine.

The combine consists of the feed part 1, the electric motor 2 of the gearbox 5 for the drive of the cutting chain and the rotational feed of the bar, the shearing bar 4, the fire shield 5, the rotary shield 6 with hydraulic drive, the receiving funnel 7 and the irrigation unit 8.

The working and loading body of the combine is the shearing bar 4, which produces a large chip from the bottom surface and at the same time transports coal and rock to the conveyor side along the chute .9.

The movement of the combine to the bottom, to a depth of 200-250 mm, is carried out frequently and is synchronized with the rotation of the bar with the help of the profile disk W and the lever system 11, which acts on the friction clutch 12 of the feeding part. The broken material is carried away by a 13 bar cutting chain fitted with scraped-fists on a tray. From the tray, the materials along the curved part of the bar are guided to the conveyor.

Separate excavation of the material is achieved by separating the packs of coal by stratification until they are completely trimmed. Separation of coal from waste rock produces a shield 6, which is driven by a pump hydraulic cylinder and a hydraulic accumulator. The lifting and onus of the shield is carried out by the hydraulic system during the transfer of the spool by sectors fixed on the rotating bar.

The movable shield in the vertical position reflects the flow of coal and unloads it onto the conveyor. When the shield is lowered, the destructible rock layer is thrown by the chain of the bar beyond the conveyor into the worked-out space. In this case, the shield only protects the conveyor from accidentally hitting rock.

The barbed shield 6 consists of a base 14, a removable upper part 15 and serves to protect the maintenance personnel of the mounting of the irrigation unit, as well as stripping the soil from the falling upper coal pack. The funnel 7 serves to receive and guide the material being transported along the curved portion of the bar. The irrigation device is powered by a pump from the tank-wagon and produces light extinguishing at the bottom when coal and rock are broken. The harvester can be assembled both for the right and for the left aabo. For seams of different thickness, appropriate bar sizes are set.

Subject invention

1. Coal harvester working with. Frames: s of the conveyor, with an executive organ in the form of a shearing bar, OI I: 1: and with the fact that, for the purpose of separate excavation of the corners and along), the shear bar is made rotating with respect to the horizontal axis, parallel to the bed of the reservoir and the perpendicular E face of Lava slaughter, with simultaneous transport of the material along the b: a; pa and subsequent separation of the coal and rock flows.

2. -Performance-by-comb. It is characterized by the fact that, with the purpose of transporting the material along the ba; pa, the ice cream is provided with a tray along which the i6apa is moved, it is abraded by transporting scrapers.

3.-The form is executed by the i-kayna lo pp. il-l 2, about tl and h.atascha with the fact that, in order to separate coal and rock flows, "hell, the conveyor-line is hinged and fortified a: the body of the combine shield, kinematic-I connected with a bar and: Pvcr: ivyayuSHCHY pipeline when issuing the breed.

4. Far-ma. Combine performance by 1-3, that is, in order that the bar can be rotated for the iCnyoKa combine, a bar is used, at which the base attached: to the rotating block, is curved At an angle of 45 ° to the plane the bar.
