fig. 2 is a schematic structural view of a knife cutting device of a sewage delivery pump with a knife cutting device provided by the utility model.

In the figure: 1 base, 2 pump bodies, 3 water inlets, 4 connecting discs, 5 cutting devices, 501 through holes, 502 cutting teeth and 503 extrusion bumps.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a sewage delivery pump with a knife cutting device comprises a base 1 and a pump body 2, wherein the pump body 2 is installed on the base 1, a water inlet 3 is formed in one side of the pump body, a connecting disc 4 is arranged at the joint between the water inlet 3 and the pump body 2, an accommodating cavity 6 is formed in the connecting disc 4, the knife cutting device 5 is detachably installed in the accommodating cavity 6, through holes 501 are formed in the knife cutting device 5 in a circular array, three through holes are formed in the knife cutting device 5, two sides of the inside of each through hole are provided with convex cutting teeth 502, and an extrusion bump 503 is arranged in the middle of the outer side of each through hole;

more specifically, sword is cut device 5 and is circular structure, the internally mounted of the pump body 2 has the main shaft, the middle part of sword is cut device 5 is provided with the groove of wearing with main shaft looks adaptation, the outside of sword is cut device 5 and is circular array and is provided with the fixed mounting hole, the internally mounted locking screw of fixed mounting hole, sword is cut device 5 and is installed in the chamber 6 that holds between connection pad 4 and the pump body 2 through fixed mounting hole and locking screw, connection pad 4 and the pump body 2 are through Luo jin screw demountable installation, sword is cut device 5 and is installed in the one side that is close to the pump body 2 inside, be provided with the space between the inner wall of connection pad 4 and the sword is cut device 5.
