SU71690A1 - Belt conveyor to coal miner - Google Patents

Description

The disadvantages of the known constructions of belt conveyors to the coal combine are that as the combine progresses along the slaughter, the conveyor must be dismantled and transferred to the place of the new work of the combine.

Distinctive feature

the proposed belt conveyor is C-shaped; the lower branch of the conveyor is connected directly to the combine, and the upper is connected to the combine by means of a carat, which bends around the roller with the axis fixedly fixed in the drift.

Such a conveyor design creates the possibility of following it behind the combine as the latter moves in the face.

The drawing schematically shows the installation of the proposed belt conveyor.

The proposed belt conveyor has two tensioning heads / and 5. The lower head / is a small scraper conveyor, which serves to clean the harvested harvester 3

coal In order to avoid the impact of transfers of the combine on the work of the conveyor, the lower head / is attached to the combine on a hinge. The upper tension head 2, located above the combine, is fastened to the latter by means of a rope 4, rounding, its roller 5 with an axis fixedly fixed in the drift. To create the tension of the conveyor, the leading part of the upper cutting machine of the combine is used. The drive 6 of the conveyor is located above the collecting conveyor 7 on a special device with a window 8 through which the coal is unloaded. The coal is unloaded using a drop knife from the cargo branch 9 of the conveyor to the collecting conveyor 7. The rollers 10 and // are supporting and guiding.

During operation, combine 3 moves in the direction of the arrow (see drawing) and there is no lower tension head / conveyor behind it. In this case, the upper head 2 of the conveyor moves in the direction opposite to the movement of the combine, i.e. to the assembly

transporter. The extension of the cargo branch 9 of the conveyor is due to the slave branch J2.

The tension of the conveyor remains unchanged, since the upper tension head 2 sweat is not behind the rope, which is released due to the movement of the combine.

At the end of the combine operation cycle, the lower tensioning head / conveyor will be located at the driftway opposite to drive 6. The chassis stopper of the upper cutting machine of the combine is released, while the conveyor belt is loosened and disconnected at the joining point. By means of a manual winch mounted on the actuator 6, the conveyor belt is wound into a coil. Then drive the conveyor through

the ropes thrown over the blocks are connected to the combine and, together with the latter, moves to a new place where the conveyor belt is unwound and a new work cycle begins.

Subject invention

The belt conveyor to the coal combine is distinguished by the fact that in order to follow the combine as the latter moves into the face, the conveyor is given a C-shaped form, the lower branch of the conveyor being connected directly to the combine, and the upper branch is connected to the combine by means of a rope bending around roller with an axle fixed in the drift.
