Description

Self-collapsing conveyor heads are known for mechanized excavation of coal niches. However, they do not provide mechanized coal extraction across the entire thickness of the seam, and the burr out of the coal pack at the roof is carried out with the help of jackhammers.

The proposed self-cutting drive head of the conveyor, due to the vertical arrangement of the axis of the working body, provides for excavation of the angle across the entire thickness of the reservoir due to the use of removable disks, the length of the string being determined by the radius of rotation of the axis of the working body. An electric motor and a conveyor drive reducer are used to rotate the cutting body when digging depleted.

FIG. 1 shows a device of the proposed self-collapsing conveyor drive head; in fig. 2 shows a diagram of the operation of a self-cutting head with a KSP-3 conveyor and with the MK-1 multi-combine complex in the following positions: a) before shifting the excavation machines and the conveyor; b) after shifting and self-cutting of all organs; c) the grooves of the poor and strips of coal maschine; d) advancing and self-cutting machines for removing the next strip of coal.

The self-destructive drive head of the conveyor consists of a vertically located rotary drum 1, a reservoir adjustable in capacity by interchangeable discs 2, a conveyor drive gear 5, an electric motor 4 of the conveyor, a coupling 5 turning on the upper sprocket 6 of the loading shield 7, a rotary jack 8, a drum 9.

The recess of the poor W in the area of the drive heads And the conveyors 12 is made by means of a vertically arranged rotary drum /, mounted on the body of the drive head of the conveyor.

To rotate the drum, an electric motor 4 and a reducer 3 of the drive head of the conveyor are used during its operation without load. A hydraulic jack 8 is used to rotate the drum / at an angle of up to 30 ° to both sides of the axis of the gearbox.

No. 144806-2. The executive bodies 13 of the excavation machines 14, as well as the drum / self-hauling into the coal seam during the shifting. Self-cutting coal is removed by conveyor scrapers.

The proposed head is designed to work on seams with a thickness of 0.7-1.2 m with a dip angle of 0-15 °.

The Giprouglemash Institute, in its conclusion, notes that the proposed self-destructive head is new in design and allows the use of excavation machines MK-1 in combination with it.

The proposed head, noted at the conclusion of the Sibgiprogormash Institute, will speed up and facilitate the excavation of coal in niches and eliminate downtime of excavation machines.

In addition, niches that are removed by known methods are usually well advanced, which requires the use of a fastener. The proposed head allows for niche excavation without attachment.

Subject invention

Self-tapping with a horizontally closed chain conveyor drive head, for mechanization of niche excavation in the drive heads area, loading coal onto a conveyor, consisting of a vertical cutting drum, a power-adjustable reservoir, the bar of which is fixed on the drive of a KSP-3 conveyor operating in a complex with a multi-combine installation MK-1, characterized in that an electric motor and a conveyor drive reducer are used to rotate the cutting body when digging a niche, and the cutting body is made to dig a niche of a certain length rotary around the vertical axis of the gearbox drive head conveyor.
