The invention relates to a hose retracting device used when coal slime is transported by pipelines, which integrates material transportation and hose retraction into a whole. The structure of the invention comprises a hose, a rotary table, a power head and a frame; wherein, the hose twines on the rotary table; the power head and the rotary table which can rotate are both arranged on the frame. The device not only solves the problem of the flexible connection between a fixed tube and an advancing pump; the pump can also advance without stop and a power driving shrinking hose is adopted in the hose twining, thus reducing labor intensity; the retracting device is simple in structure, thus reducing the occupying space of the hose and being flexible in distribution.
