Description

Technical Field

[0001] The utility model relates to the technical field of bridge-type transfer machines, in particular to a bridge-type transfer machine with a controlled coal flow automatic conveyor. Background Art

[0002] The transfer machine is an indispensable mechanical equipment used in conjunction with scraper conveyors and belt conveyors in underground coal mining. In the coal comprehensive mining process, the coal mined by the coal mining machine is first sent to the tail of the transfer machine, the flexible trough, the middle trough, the crusher, the climbing section, the head and the coal outlet through the scraper conveyor and then to the belt conveyor.

[0003] The bridge-type transfer machine is installed in the lower chute of the comprehensive mining working face. It is an important equipment that transfers the coal transported from the working face to the belt conveyor. There are two unloading baffles on the left and right at its unloading end to guide the coal flow to be unloaded to the center line of the belt to prevent the unloaded coal blocks from sliding to the outside of the belt. However, when the coal blocks fall into the trough of the bridge-type transfer machine for transportation, the coal blocks are piled up together, making the coal pile high and falling from the coal baffles on both sides, causing transportation waste.
