Background

The buried scraper conveyer is a conveyer which adopts scraper chain traction and transports bulk materials in a groove body, and is widely applied to industries such as coal, chemical industry, ports, metallurgy and the like. When the buried scraper conveyor conveys bulk materials with high humidity and high viscosity, such as coal, mud and the like, the materials are very easily adhered to the surface of the bottom plate of the groove body, the scraper chain running to the position is heightened by the adhered materials, the problem of chain floating is caused, the more the adhered materials are gathered, and the conveying capacity of the buried scraper conveyor is reduced; meanwhile, after the scraper on the scraper chain is abraded, the adhesion of materials is further aggravated, the scraper must be replaced in time, and the operation and maintenance cost of the buried scraper conveyor is increased.

Disclosure of Invention

Aiming at the problems that the existing scraper chain of the buried scraper conveyer is easy to float and the equipment maintenance and operation cost is high due to the replacement of a worn scraper, the invention provides the buried scraper conveyer with the anti-floating chain. This bury scraper conveyor's the leading flank of preventing floating the scraper blade and the bottom plate contained angle of the cell body of traffic direction is for being greater than 110 degrees and being less than 130 degrees obtuse angles, the material will prevent floating the scraper blade to the effort of the leading flank of preventing floating the scraper blade and compress tightly on the bottom plate of cell body, and simultaneously, the acute angle between the leading flank of preventing floating the scraper blade and the bottom surface will adhere in time to scrape the material on the surface of the bottom plate of cell body, the floating chain problem that leads to on the surface of the bottom plate of cell body because of the material adhesion has been avoided, the cleaning work efficiency of bulk material has been improved. In addition, after the anti-floating scraper is worn, the anti-floating scraper is pressed on the surface of the bottom plate of the groove body all the time by adjusting the position of the fixing bolt in the countersunk long and narrow adjusting hole, so that the worn anti-floating scraper can still keep good transportation performance, the service life of the anti-floating scraper is prolonged, and the operation and maintenance cost of the buried scraper conveyor is reduced.

The specific technical scheme is as follows: an anti-floating chain embedded scraper conveyor comprises a groove body, a driving chain wheel assembly, a tensioning device, a driven chain wheel assembly and an anti-floating scraper chain; the trough body consists of a feed inlet, a left side plate, a right side plate, a bottom plate, a sliding clamping groove and a discharge opening; the driving chain wheel component consists of a driving chain wheel, a left sliding supporting seat, a right sliding supporting seat and a power source; a left sliding support seat and a right sliding support seat of the driving chain wheel assembly are respectively and slidably supported in sliding clamping grooves at two sides of the rear end of the groove body; the tensioning device is used for tensioning the anti-floating scraper chain through the left sliding supporting seat and the right sliding supporting seat; the anti-floating scraper chain is meshed with the driven chain wheel shaft and the gear teeth on the driving chain wheel.

The anti-floating scraper chain consists of an anti-floating scraper, an inner side plate, a T-shaped side plate, a fixing bolt, a rotating shaft and a pin shaft; the rotating shaft is hinged with the inner side plate and the T-shaped side plate of the adjacent chain link through a pin shaft; the anti-floating scraper is fixed on the T-shaped side plates at two sides of the chain link by fixing bolts.
