An anti-blocking chute device at the transfer point of a belt conveyor

Abstract

The invention relates to an anti-blocking chute device of a belt conveyor transferring point, and relates to a large belt conveyor for a surface mine. The anti-blocking chute device solves the current technical problem that a chute is easily blocked at the belt conveyor transferring point. The anti-blocking chute device comprises a feeding belt conveyor, a receiving belt conveyor connected with the feeding belt conveyor and a transferring chute at the transferring point of the feeding belt conveyor and the receiving belt conveyor. The transferring chute is installed on the head of a discharging point of the feeding belt conveyor and moves along with the feeding belt conveyor. The transferring chute comprises a planar receiving plate, a curved surface receiving plate, a tooth type synchronous belt, a buffering and material blocking rubber belt, a fixed scraper plate, a belt driving wheel, a buffering belt supporting plate, a supporting frame, a main support, a side baffle, a belt driven wheel and a driving motor. The anti-blocking chute device enables the belt conveyor transferring point to effectively resist impact of materials and prevents the materials from accumulating through movement.

Description

technical field [0001] The invention relates to a large-scale belt conveyor used in open-pit mines, in particular to an anti-blocking chute device at the transfer point of the large-scale belt conveyor. Background technique [0002] With the large-scale mining of open-pit mines, the application of large-capacity, high-speed belt conveyors for rock drainage operations in mines is becoming more and more widespread. Such as figure 1 As shown, for the large-scale belt conveyor used in open-pit mines, it includes two high-speed (belt speed greater than 4m / s) belt conveyors: feeding belt conveyor 1, and connecting belt conveyor 2 connected with the feeding belt conveyor. Material and dust suppression, the transfer point of the feeding belt machine 1 and the receiving belt machine 2 is provided with a transfer chute 3, and the transfer chute 3 is installed at the head of the feeding belt machine 1 discharge point, and moves together with the feeding belt machine. When the materia...

AI Technical Summary

Problems solved by technology

When the material is blocked by the chute baffle during high-speed movement, it will harden and hang on the baffle. Due to the viscosity and moisture content of the material, the hardened material on the baffle will continue to increase, often causing a large amount of material to stick to the chute during the work process. Especially in the winter in the north and the open-air operation in the rainy season in the south, the chute is more likely to be blocked, causing accidents and major economic losses
