the secondary cutting shaft 26, so that the waterweeds stripped from the impeller 42 can be cut secondarily, and further the cut waterweeds can be output outwards from the water outlet pipe 64 along with the water flow, and further the winding of the, at this time, the sensor 63 stops detecting the water flow in the water inlet pipe 62, and then the power on the electromagnetic switching iron core 38 is cut off, the pushing head 39 moves rightwards under the elastic force of the electromagnetic switching spring 40, and then pushes the sliding ring 36 to move rightwards, and then the sliding rod 35 drives the spline shaft 33 to move rightwards and compresses the spline shaft spring 32 to reset, at this time, the connecting shaft 48 and the reciprocating bevel gear 49 drive the rotating roller 46 to move rightwards, and then the reciprocating bevel gear 49 is disengaged from the positioning bevel gear 59, at this time, the reciprocating push disc 52 and the fixed disc 53 move rightwards and reset under the action of the rotating roller 46, and then the stripping plate 55 is pushed by the stripping rod 54 to extend into.

The invention has the beneficial effects that: according to the invention, the space inside the water pump is refined, the waterweed filter screen and the primary cutting knife are added inside the water pump, the waterweed entering the pump is blocked and cut, the reciprocating movement of the stripping plate is realized by utilizing the rotating roller capable of reciprocating left and right, the waterweed wound on the upper side of the impeller is stripped and secondarily cut, the blockage of the whole water pump caused by the waterweed entering the water pump is effectively prevented, the winding of the impeller by the waterweed is also prevented, the overlarge output power of the motor is further caused, and the equipment is damaged.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
