Zusammenfassung: | The invention relates to a dual-purpose belt conveyor with a variable wheel tread and a variable elevation, in particular to a belt conveyor which is applied in an integrated coal mining machine of a coal mine and is connected with a one-purpose belt conveyor for transportation. The belt conveyor comprises a body formed by connecting a plurality of rack units, and one end of the body is provided with a device connected with a heading machine. The belt conveyor is characterized in that the other end of the body is provided with a pulley with a variable wheel tread device which rolls on the pulley track of a primary belt conveyor or the pulley track of a scraper conveyor, and a variable elevation device is arranged at the connection part of two adjacent rack units on the upper middle section of the body. Due to the use of the variable wheel tread device, the dual-purpose belt conveyor can conveniently switch between the scraper conveyor and the master belt conveyor, thereby increasing the operating efficiency a |
