Washing vortex pump with material size selection structure

The invention relates to the technical field of vortex pumps, in particular to a washing vortex pump with a material size selection structure. The vortex pump comprises a pump shell and an impeller, the pump shell is communicated with a water inlet pipe and a water outlet pipe, the water inlet pipe is provided with an anti-reflux body, the water outlet pipe is provided with a selection body, the selection body comprises an adjusting structure and an adjusting plate, the pump shell is provided with a transmission opening, the impeller is connected with a transmission shaft, and the impeller is connected with a fluid breaking body. By arranging the adjusting structure, a shifting rod is shifted to drive a gear ring to rotate in an annular groove, so that the gear ring drives a gear rod meshed with the gear ring to rotate in a vertical groove, and then a screw sleeve in threaded connection with the gear rod drives an adjusting plate to rotate in a side opening, so that the deflection angle of the adjusting plate
