Technical field
The utility model is related to water pump technology more particularly to a kind of cutting pumps being conveniently replaceable blade.
Background technology
Sewage cutting pump, is also submersible cutting pump, draws water for blowdown, due to addition of advanced cutting knife, making to cut
Pump is cut under severe conditions by dross, plastic products and the fibrous object chopping in catch pit and smooth discharge, is not necessarily to
It is artificial go cleaning to cheat in dross and suspended matter, saved city and had stable political situation engineering spending.
Solid waste in sewage is more, the work of the high intensity of cutting pump so that cutter head is very easy to damage, becomes
It is blunt.The cutter head of cutting pump especially moving knife changes very cumbersome.Wasting manpower and material resources, or even the cutting pump more tool changing that has
Head needs impeller wheel portion to replace together, and cost increases.Pump body structure is complicated simultaneously, and dismounting component is excessive, increases pump damage
Probability.
Utility model content

Connect one end of the motor；The stationary knife is set on the pump cover.
Compared with prior art, the beneficial effects of the utility model are mainly reflected in：Moving knife is set among impeller, follows leaf
Wheel rotates together, and when pump operates, the reciprocal of moving knife and stationary knife ensure that thoroughly smashing to pieces for solid waste.Moving knife upper slitter
The design of handle and elastic collet, causes stubbed in moving knife damage or use for a long time, need to unscrew elasticity
Collet takes out moving knife, is conveniently replaceable, while the moving knife also allows for batch production batch production.
Description of the drawings
Fig. 1 is the structure chart for the cutting pump that blade is conveniently replaceable in one embodiment of the utility model；
Fig. 2 is the combination assumption diagram of elastic collet and moving knife in one embodiment of the utility model；
Fig. 3 is the structure chart of moving knife in one embodiment of the utility model.
Specific implementation mode
It, below will be to the technology of the utility model to keep the purpose of this utility model, technical solution and advantage clearer
Scheme is further described.
As shown in Figure 1, Figure 2 and described in Fig. 3, the utility model proposes a kind of cutting pump being conveniently replaceable blade, including the pump housing 1,
