The scraper chain of the anti-floating chain can avoid the problem of floating chain caused by the adhesion of materials on the surface of the bottom plate of the conveying groove, and improves the working efficiency of cleaning bulk materials; meanwhile, after the anti-floating scraper is worn, the anti-floating scraper is pressed on the surface of the bottom plate of the conveying groove all the time by adjusting the position of the fixing bolt in the long and narrow countersunk adjusting hole, so that the worn anti-floating scraper can still keep good conveying performance, the service life of the anti-floating scraper is prolonged, and the operation and maintenance cost of equipment is reduced.
Description
Technical Field
The invention relates to the technical field of bulk material conveying, in particular to scraper conveyor equipment for bulk materials.
Background
The scraper conveyer is a conveyer which adopts scraper chain traction and transports bulk materials in a transport tank, and is widely applied to industries such as coal, chemical industry, ports, metallurgy and the like. When the scraper conveyor conveys bulk materials with high humidity and high viscosity, such as coal, mud and the like, the materials are very easy to adhere to the surface of the bottom plate of the conveying groove, 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 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 scraper conveyor is increased.
Disclosure of Invention
The invention provides a scraper chain capable of preventing chain floating, aiming at the problems that the existing scraper chain of a scraper conveyor is easy to generate chain floating and the equipment maintenance and operation cost is high due to replacement of a worn scraper. Because the included angle between the front side face of the anti-floating scraper and the bottom plate of the transportation tank in the running direction is an obtuse angle which is larger than 110 degrees and smaller than 130 degrees, the anti-floating scraper is pressed on the bottom plate of the transportation tank by the acting force of the material on the front side face of the anti-floating scraper, and meanwhile, the material adhered to the surface of the bottom plate of the transportation tank is scraped by the acute angle between the front side face and the bottom face of the anti-floating scraper in time, so that the problem of floating chains caused by the adhesion of the material on the surface of the bottom plate of the transportation tank is avoided, and the cleaning work efficiency of the scattered materials. In addition, after the anti-floating scraper is worn, the anti-floating scraper is pressed on the surface of the bottom plate of the conveying groove all the time by adjusting the position of the fixing bolt in the long and narrow countersunk adjusting hole, so that the worn anti-floating scraper can still keep good conveying performance, and the service life of the anti-floating scraper is prolonged.
The specific technical scheme is as follows: a scraper chain of an anti-floating chain comprises 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.
The anti-floating scraper comprises a front side surface, a rear side surface, a bottom surface, a top surface and a countersunk long and narrow adjusting hole; the front side surface faces the running direction of the scraper chain, and the included angle between the front side surface and the bottom surface is more than 30 degrees and less than 50 degrees; the included angle between the front side surface and the bottom plate of the transportation tank in the running direction is more than 110 degrees and less than 130 degrees.
The included angle between the front side surface and the bottom surface of the anti-floating scraper is an acute angle.
The included angle between the front side face of the anti-floating scraper and the bottom plate of the transportation tank in the running direction is an obtuse angle.
The floating-prevention scraper has the beneficial effects that because the included angle between the front side surface of the floating-prevention scraper and the bottom plate of the transportation tank in the running direction is an obtuse angle which is more than 110 degrees and less than 130 degrees, the floating-prevention scraper is tightly pressed on the bottom plate of the transportation tank by the acting force of materials on the front side surface of the floating-prevention scraper, and meanwhile, the materials adhered to the surface of the bottom plate of the transportation tank are timely scraped off by the acute angle between the front side surface and the bottom surface of the floating-prevention scraper, so that the floating chain problem caused by the adhesion of the materials on the surface of the bottom plate of the transportation tank is avoided, and the cleaning work efficiency of the. In addition, after the anti-floating scraper is worn, the anti-floating scraper is always pressed on the surface of the bottom plate of the conveying groove by adjusting the position of the fixing bolt in the long and narrow countersunk adjusting hole, so that the worn anti-floating scraper can still keep good conveying performance, the service life of the anti-floating scraper is prolonged, the cleaning work efficiency of bulk materials is improved, and the operation and maintenance cost of equipment is reduced.

Detailed Description
As shown in fig. 1, 2 and 3, the scraper chain of the anti-floating chain comprises an anti-floating scraper 1, an inner side plate 2, a T-shaped side plate 3, a fixing bolt 6, a rotating shaft 4 and a pin shaft 5; the rotating shaft 4 is hinged with the inner side plate 2 and the T-shaped side plate 3 of the adjacent chain link through a pin shaft 5; the anti-floating scraper 1 is fixed on the T-shaped side plates 3 at two sides of the chain link by fixing bolts 6.
The anti-floating scraper 1 comprises a front side surface 11, a rear side surface 12, a bottom surface 13, a top surface 14 and a countersunk long and narrow adjusting hole 15; the front side surface 11 faces the running direction of the scraper chain, and the included angle between the front side surface 11 and the bottom surface 13 is more than 30 degrees and less than 50 degrees; the angle between the front side 11 and the trough floor 7 in the direction of travel is greater than 110 degrees and less than 130 degrees.
The included angle between the front side surface 11 and the bottom surface 13 of the anti-floating scraper 1 is an acute angle.
The included angle between the front side surface 11 of the anti-floating scraper 1 and the bottom plate 7 of the transportation groove in the running direction is an obtuse angle.
When scraper conveyor transports bulk material, because the contained angle between the leading flank 11 of preventing floating scraper 1 and the transport vechicle bottom plate 7 of traffic direction is for being greater than 110 degrees and being less than 130 degrees obtuse angles, the material compresses tightly on transport vechicle bottom plate 7 to the effort of the leading flank 11 of preventing floating scraper 1, and simultaneously, the acute angle between the leading flank 11 of preventing floating scraper 1 and bottom surface 13 in time scrapes the material of adhesion on transport vechicle bottom plate 7 surface, avoided because of the material adhesion float the chain problem that leads to on the surface of transport vechicle bottom plate 7, the clearance work efficiency of bulk material has been improved. In addition, after the anti-floating scraper 1 is worn, the anti-floating scraper 1 is always pressed on the surface of the bottom plate 7 of the conveying groove by adjusting the position of the fixing bolt 6 in the countersunk long and narrow adjusting hole 15, so that the worn anti-floating scraper 1 can still keep good conveying performance, the service life of the anti-floating scraper 1 is prolonged, the cleaning work efficiency of bulk materials is improved, and the operation and maintenance cost of equipment is reduced.
