Description

Technical Field

[0001] The utility model relates to the technical field of mine transportation equipment, in particular to a transfer machine groove with replaceable wing plates. Background Art

[0002] The transfer machine is underground transportation equipment in coal mines. It has large transportation capacity and high strength requirements for structural parts. It is widely used in coal transportation in various coal mines. The transfer machine is used in conjunction with the scraper machine on the working face. When the coal is cut off by the drum cutter of the coal mining machine, the scraper conveyor transports the coal to the transfer machine, and then the transfer machine transports the coal to the belt conveyor, and the belt conveyor transports the coal to the ground coal bunker, completing the cycle of coal mining, transportation and becoming industrial raw materials. The groove is the first section of the chute of the raised slope section of the transfer machine. Its wing plate adopts a large arc transition, which can reduce the wear during use and increase the amount of coal passing.

[0003] Since the wing plate is in an arc shape, the scraper chain and the scraper will be tightened due to tension during operation, causing the scraper and the wing plate to run in close proximity for a long time. After a period of time, the wing plate will be severely worn and the scraper may have hidden dangers such as chain jumping. The wing plate of the traditional groove is directly welded to the trough body, which is difficult to replace. Utility Model Content
