The invention discloses a telescoping mechanism, a belt conveyor and a crushing and screening device, relates to the technical field of engineering machinery and solves the technical problems in the prior art that a belt is prone to loosening and being damaged. The telescoping mechanism comprises a mounting base, a first sliding rail, a first support, a first telescoping device, a second support, a second sliding rail and a second telescoping device. The first sliding rail is connected with a base body of the first telescoping device and the mounting base. The first support is connected with the telescopic portion of the first telescoping device and the second sliding rail. The second sliding rail is connected with the base body of the second telescoping device. The second support is connected with the telescopic portion of the second telescoping device. The belt conveyor and the crushing and screening device are respectively provided with the telescoping mechanism. The telescoping mechanism is used for prolonging the service life of the belt of the belt conveyor and improving use convenience.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a telescopic mechanism, a belt conveyor provided with the telescopic mechanism, and crushing and screening equipment provided with the belt conveyor. Background technique [0002] The mobile crushing station is mainly composed of crushing host, receiving hopper, belt conveyor, frame, feeder, chassis and other components. Belt conveyor is a kind of machinery that is driven by friction to transport materials in a continuous manner. It is mainly composed of frame, conveyor belt, idler roller, roller, tensioning device, transmission device, etc. [0003] During the working process of the mobile crushing station, the main crushing machine crushes the incoming materials, and the belt conveyor transports the crushed materials from the main crushing machine to the storage point for crushed materials. [0004] In actual production, after the crushing station works for a cer...
