Further, the screw rod is being provided with connecting portion with being connected shaft connection place, and the connecting portion size is less than screw rod
Size and it is solidified as a whole structure with screw rod, screw rod is threadedly coupled by connecting portion with connecting shaft.
Specifically, the cutter include being enclosed on annulus on connecting portion, and it is solidified as a whole structure and along circle with annulus
The uniform blade of ring center circumferential, circle ring center hole match with connecting portion.
Specifically, the filter mechanism is provided centrally with the through hole for being easy to screw rod to pass through, and along filter mechanism center circle
Zhou Junbu and the three arc vias passed through for medium.
Further, filling pumping hole is additionally provided with the pump case, the filling pumping hole is provided with plug.
Further, the pump case is provided with supporting mechanism by discharge room one end.
Compared with prior art, the utility model has the advantages that：
The utility model uses screw pump, and simple and compact for structure, convenient disassembly, appearance and size is small, has higher lift,
Filter mechanism can filter to larger fiber, weeds, waste paper etc., and cutter can be to filter before being arranged on filter mechanism
Larger fiber that structure intercepts, weeds, waste paper etc. carry out cutting and blended, and ensure the debris chokelesspump after filter mechanism
Body, set on the pump housing discharging hole can well in discharging pump residual sewage, in case of emergency can also release pressure in time, subtract
Few accident.Pump increase suction can be filled by filling being arranged on when pump is declined using rear sealing effectiveness for a long time and caused self-priming effect to be deteriorated for pumping hole
Upper ability, for screw rod with connecting shaft to be threadedly coupled convenient disassembly, the setting of supporting mechanism causes pump to be fitted in installation or use
Answering property is more preferable.
