CONVEYING PIPELINE, BOOM SYSTEM AND OPERATING EQUIPMENT

摘要

A conveying pipeline for boom system comprises a first pipe (231), a second pipe (233) and a rotating pipe (31), wherein the first pipe (231) and the second pipe (233) are fixed relative to each other. The inlet of the rotating pipe (31) communicates with and is connected rotatablely to the outlet of the first pipe (231). The rotating pipe (31) can be rotated to at least a first operating position and a second operating position. The outlet of the rotating pipe (31) communicates with the inlet of the second pipe (233) in the first operating position, and the communication is cut off in the second operating position. A boom system and an operating equipment provided with the conveying pipeline are also provided. The conveying pipeline can be used for long-distance or short-distance distribution, and can reduce wear on the components and operation cost.
