Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the embodiment provides an efficient three-blade cutting type sewage pump, which includes a motor 1, a casing 2 is installed on one side of an output end of the motor 1, a water inlet is formed in an end surface of the casing 2, a water outlet 6 is formed in an outer side of the casing 2, a rotating shaft 10 is installed on an output shaft of the motor 1, one end, away from the motor 1, of the rotating shaft 10 extends out of the casing 2, an impeller 11 is fixedly installed on the outer side, located inside the casing 2, of the rotating shaft 10, the motor 1 provides power for the rotating shaft, and the rotating shaft 10 can drive the impeller 11 to rotate to generate suction to water so as to enable the water to flow.

The end outside fixed mounting that stretches out of axis of rotation 10 has cutting knife 5, and same motor 1 provides power for cutting knife 5, at the in-process of water pump work, because aquatic can mix there are various rubbish: for example disposal bag, leaf, paper handkerchief or pasture and water etc. lead to going on of water pump mouthful jam easily, can lead to 11 stall of impeller in serious time, cause the condition that the motor burns out, and the cutting knife then can smash rubbish, avoids rubbish to influence the normal work of water pump. The inner side of the cutting knife 5 is provided with a protection ring fixedly connected with the shell, the other end of the cutting knife 5 is fixedly provided with a protection cover 3, and the protection ring can prevent water from entering the water pump between the cutting knife 5 and the shell 2, so that garbage can be prevented from entering the water pump between the cutting knife 5 and the shell.
