The invention relates to a multifunctional hose pump. The multifunctional hose pump comprises a hose pump body and a motor, a transmission shaft, two hoses with different diameters and two rotor devices are arranged in the hose pump body, one hose, two rotors and two fixed hose bolts are arranged on the front segment of the hose pump body, one hose, three rotors and three fixed hose bolts are arranged o the rear segment of the hose pump body, the two hoses with the different diameters convey media with different concentrations, the hose with the large diameter and located on the front segmentis used for conveying water, the hose with the small diameter and located on the rear segment of the shell is used for conveying liquid fertilizer, the transmission shaft drives the two rotor devicesto extrude the hoses in the hose pump body, and the conveying media are extruded to a discharging opening from a feeding opening. The multifunctional hose pump facilitates feeding, can convey two sameor different media at the same time, and is high in work efficiency. The problem that a hose pump is single in use function is solved.
