Description

Technical Field

[0001] The utility model relates to the technical field of concrete construction equipment, in particular to a telescopic rotary material distribution device. Background Art

[0002] The construction of water conservancy and hydropower projects often involves a large amount of concrete pouring construction, and the way concrete is put into the warehouse will directly affect the construction speed and quality of the dam body. Conventional ways of putting concrete into the warehouse include pumping and belt conveyor transportation. Pumping generally uses pipelines to transport concrete. Pipeline transportation has strict requirements on the gradation, particle size, slump, and workability of concrete. First-grade and second-grade concrete can be transported by pipeline, while dam construction often involves third-grade or fourth-grade concrete.
