Description

Technical Field

[0001] The utility model belongs to the technical field of material transportation equipment, in particular to a belt protection device for a belt conveyor. Background Art

[0002] At present, belt conveyors are common material conveying equipment in various mining areas. Existing belt conveyors generally include components such as frames, rollers, tension rollers and belts. When the belt conveyor is running, the material load is almost entirely applied to the belt surface. When sharp metal objects are mixed into the material, the density of the metal objects is greater than that of common ores, which will cause the belt to be overloaded, affecting the safe and stable operation of the belt conveyor. When the belt is overloaded, it will also be torn, causing damage to the belt, and the machine has to be shut down for maintenance or replacement, which seriously affects the continuity of production and transportation.

[0003] In the prior art, the patent document with publication number "CN217837255U" discloses a comprehensive protection device for preventing belt tearing, comprising a reciprocating coal conveying belt, a de-ironing device being arranged above the upper belt of the conveying belt, a longitudinal tearing sensor platform of the conveying belt being arranged between the upper belt and the lower belt of the conveying belt in front of the de-ironing device along the running direction of the upper belt, a touch sensor for detecting metal objects penetrating the upper belt being arranged between the upper belt and the lower belt below the de-ironing device, a baffle being arranged on the upper end face of the lower belt, a coal pile sensor being arranged at the corresponding baffle outside the side of the conveying belt, the longitudinal tearing sensor platform of the conveying belt, the coal pile sensor and the touch sensor being respectively connected to the start-stop control alarm system of the conveying belt. By adopting this patented technical solution, a large number of sharp iron objects mixed in the material are sucked out by setting up an iron remover, which can prevent the belt from being pierced by sharp iron objects to a certain extent. It can provide protection for the belt conveyor belt to a certain extent. However, when the belt conveyor is running, if too much material accumulates in a local area on the belt surface, it will also cause the belt surface to be overloaded, causing the local area of ​​the belt surface to be overloaded and torn and damaged, which will still affect the safe operation of the belt conveyor.

[0021] By adopting the technical solution of the present invention, when the belt conveyor is running, on the one hand, the relative height between the frame and the belt surface is kept constant, and the frame can smooth the material accumulated on the belt surface, so that the material is evenly distributed on the belt surface, and the belt surface is loaded as evenly as possible; on the other hand, when the material is fed to the belt surface through the screening roller, the screening roller evenly distributes the material, so that the material can fall as evenly as possible to at least the belt surface, avoiding unbalanced loading on the belt surface, and preventing the belt surface from being torn due to unbalanced loading, thereby ensuring continuous, safe and stable operation of the belt conveyor.

[0022] Specifically, the belt conveyor belt protection device also includes a second telescopic rod 5, one end of which is fixedly connected to the belt conveyor frame 4, and the other end of which is connected to the belt conveyor's tensioning roller 6.
