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
Aiming at the problems that the existing scraper chain of the scraper conveyor is easy to float and the equipment maintenance and operation cost is high due to the replacement of a worn scraper, the invention provides an adjustable chain scraper for preventing the chain from floating. Because the contained angle between the transport tank bottom plate of the front side of the chain scraper blade of the adjustable floating-proof chain and the running direction is an obtuse angle which is larger than 110 degrees and smaller than 130 degrees, the acting force of the material on the front side of the chain scraper blade of the adjustable floating-proof chain compresses the chain scraper blade of the adjustable floating-proof chain on the transport tank bottom plate, and meanwhile, the acute angle between the front side and the bottom surface of the chain scraper blade of the adjustable floating-proof chain timely scrapes the material adhered to the surface of the transport tank bottom plate, so that the floating problem caused by the adhesion of the material on the surface of the transport tank bottom plate is avoided, and the cleaning work efficiency of the bulk material is improved. In addition, after the chain scraper of the adjustable floating-proof chain is worn, the position of the fixing bolt in the countersunk long and narrow adjusting hole is adjusted, so that the chain scraper of the adjustable floating-proof chain is always pressed on the surface of the bottom plate of the conveying groove, the good conveying performance of the worn chain scraper of the adjustable floating-proof chain can be ensured, and the service life of the chain scraper of the adjustable floating-proof chain is prolonged.
The specific technical scheme is as follows: an adjustable chain scraper for an anti-floating chain 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 face and the bottom face is an acute angle.
The included angle between the front side face and the bottom plate of the transportation tank in the running direction is an obtuse angle.
The chain scraper of the adjustable anti-floating chain is fixed on the T-shaped side plates at two sides of the chain link of the scraper chain after penetrating through the countersunk head long and narrow adjusting hole by the fixing bolt.
The adjustable floating-proof chain scraper has the beneficial effects that because the included angle between the front side surface of the adjustable floating-proof chain 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 chain scraper of the adjustable floating-proof chain is tightly pressed on the bottom plate of the transportation tank by the acting force of materials on the front side surface of the adjustable floating-proof chain scraper, and meanwhile, the acute angle between the front side surface and the bottom surface of the adjustable floating-proof chain scraper can timely scrape off the materials adhered on the surface of the bottom plate of the transportation tank, so that the floating 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 bulk materials is improved. In addition, after the adjustable floating-proof chain scraper is worn, the position of the fixing bolt in the countersunk long and narrow adjusting hole is adjusted, so that the adjustable floating-proof chain scraper is always pressed on the surface of the bottom plate of the conveying groove, the good conveying performance of the worn adjustable floating-proof chain scraper can be ensured, the service life of the adjustable floating-proof chain scraper is prolonged, the cleaning work efficiency of scattered materials is improved, and the operation and maintenance cost of equipment is reduced.

Detailed Description
As shown in fig. 1, 2 and 3, an adjustable anti-drift chain scraper 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 3 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 is an acute angle.
The angle between the front side 11 and the transport trough floor 3 in the direction of travel is obtuse.
The chain scraper of the adjustable anti-floating chain is fixed on the T-shaped side plates 2 at two sides of the chain link of the scraper chain after penetrating through the countersunk head long and narrow adjusting hole 15 by the fixing bolt 2.
When the scraper conveyor transports the bulk materials, because the included angle between the front side surface 11 of the adjustable anti-floating chain scraper and the transport groove bottom plate 3 in the running direction is an obtuse angle which is larger than 110 degrees and smaller than 130 degrees, the chain scraper of the adjustable anti-floating chain is pressed on the transport groove bottom plate 3 by the acting force of the material on the front side surface 11 of the adjustable anti-floating chain scraper, and meanwhile, the materials adhered to the surface of the transport groove bottom plate 3 are scraped in time by the acute angle between the front side surface 11 and the bottom surface 13 of the adjustable anti-floating chain scraper, so that the problem of floating of the bulk materials caused by the adhesion of the materials on the surface of the transport groove bottom plate 3 is avoided, and the cleaning work efficiency of the bulk materials is improved. In addition, after the adjustable floating-proof chain scraper is worn, the position of the fixing bolt 2 in the countersunk long and narrow adjusting hole 15 is adjusted, so that the adjustable floating-proof chain scraper is always pressed on the surface of the bottom plate 3 of the conveying groove, the good conveying performance of the worn adjustable floating-proof chain scraper can be ensured, the service life of the adjustable floating-proof chain scraper is prolonged, the cleaning work efficiency of bulk materials is improved, and the operation and maintenance cost of equipment is reduced.
