The invention discloses a hose coiler device which comprises a supporting seat. The supporting seat can support a main shaft pipe in a rotatable way; the outer side of the main shaft pipe is sheathed with an outer shaft disk which is fixedly connected with a hose reel which is mainly coaxial to the outer shaft disk; the outer shaft disk is supported by the supporting seat in a rotatable way, and is connected with the main shaft pipe through a shaft coupling. The invention also provides an engineering machine comprising the hose coiler device. The hose coiler device provided by the invention and the outer shaft disk and the main shaft pipe of the engineering machine are mutually and separately supported by the supporting seat in a rotatable way. When high-pressure oil seal damage and other faults occur in the hose coiler device, only the main shaft pipe instead of together with the outer shaft disk simultaneously is dismounted. Thereby the hose coiler device provided by the invention has the advantages of obvious reduction of the work load of maintenance operation, time conservation and labor conservation, and reduction of maintenance cost, and greatly improves the work efficiency of engineering machines.
