Technical Field
[0001] The utility model relates to the technical field of material conveying anti-blocking, in particular to an anti-blocking slide pipe structure connecting a scraper conveyor and an elevator. Background Art
[0002] At the connection between the scraper and the elevator, due to the fluidity of the material, blockage is prone to occur, resulting in production interruption or even equipment damage.

[0003] To this end, the patent with publication number CN212449177U discloses a multi-section detachable anti-blocking chute suitable for bucket elevator material transportation. Since the limestone material transported by the bucket elevator is relatively hard and contains impurities, the chute that serves the transportation function is very easy to wear, and it is difficult to replace the chute as a whole. In the rainy season or when the limestone material has a small particle size and is wet, the chute is very easy to get blocked. A multi-section detachable anti-blocking chute suitable for bucket elevator material transportation, comprising: an anti-blocking chute body (1), the chute is composed of an inlet chute (1-1), a middle chute (1-2) and an outlet chute (1-3), wherein the middle chute is composed of three chute pipes of the same size, and the three chute pipes are interconnected by flanges, one end of the inlet chute is fixedly connected to one end of the middle chute by a flange, and the other end is connected to the bucket elevator outlet pipe by a flange, and the other end of the middle chute is fixedly connected to one end of the outlet chute by a flange. The utility model is applied to bucket elevators;
[0004] Although the multi-section detachable anti-blocking chute used in the bucket elevator can be divided into multiple sections for easy disassembly during use, it is impossible to detect blockage immediately, which may damage the machine. Therefore, it is necessary to design an anti-blocking chute structure that can detect whether there is blockage and connect the scraper conveyor to the elevator. Utility Model Content
