Background technique

At present; be used to pump the sewage pump of sewage because cutting device is not set; can be got lodged in the liquid entering hole of sewage pump and stop up liquid entering hole by solids such as some branches, weeds using sewage pump to pump in the process of sewage; even be stuck in and influence motor on the water wheels and rotate; cause motor to burn out when serious, successfully pump and clean out obstruction after sewage then must be shut down, row starts sewage pump extraction sewage again; promptly lose time the operating difficulties of feasible again cleaning dirt.

Summary of the invention

The purpose of this utility model provides a kind of sewage pump of not blocked band cutting device.

The purpose of this utility model is achieved in that

The sewage pump of band cutting device, include the pump housing and be installed in motor on the pump housing, the pump housing is provided with feed pathway and liquid outlet channel, feed pathway is communicated with the formation sewage routeway with liquid outlet channel, motor shaft stretches in the feed pathway and water wheels is installed, on the pump housing in feed pathway the center is installed axis hole is arranged, axis hole circumferentially is evenly equipped with the water port outward, there is the cutting disk of a cutting planes exterior edge face, feed pathway is communicated with liquid outlet channel by the water port, and the outer end that the motor shaft of water wheels is installed is passed to be fixed with described cutting disk behind the axis hole of cutting disk and cooperated the slitting wheel that cut foreign material.

Above-mentioned slitting wheel are radioactive three cutting blades that are provided with, and the upstream face of each cutting blade and the corresponding part of the water port on the cutting disk are provided with the semicircle tank of crossing.

The corner of crossing tank on the corner of the water port on the above-mentioned cutting disk and the slitting wheel is provided with the cutting cutting edge.

Above-mentioned cutting disk by the outside mounting hole and be bolted on the pump housing in the feed pathway, the attachment face that the cutting planes on the cutting disk exceeds the mounting hole place forms an annular boss.

The axis hole of above-mentioned slitting wheel is provided with keyway, and slitting wheel are by keyway, flat key and be bolted on the motor shaft.

The utility model gives prominence to compared to existing technology and beneficial technical effects is:

1, the cutting device of the present utility model solid matters such as branch, weeds that rest on sewage pump liquid entering hole place in the working procedure of sewage pump suck the cutting device place by broken while sucking, cutting with sewage, can not stop up the liquid entering hole of sewage pump and the sewage routeway in the pump housing, do not have bigger solid in the sewage that is drawn out of, make things convenient for next step sewage treatment.

2, the utility model sewage pump of having solved prior art need be shut down the work of wasting time and energy of cleaning dirt, the working life of having guaranteed motor again.

3, of the present utility model simple in structure, working stability is reliable, and long service life is applicable on various sewage pumps and uses.
