As optional embodiment, it can be separately matched with power motor, not directly transmitted to cutting unit 12 by power distribution box.
[0029] Specifically, cutting tooth disc 121,122 each includes a plurality of axially spaced knife plates, the surface of the knife plate is provided with cutting teeth, the cutting teeth of cutting tooth disc 121 extend into the gap between adjacent cutting teeth of cutting tooth disc 122, and the cutting teeth of cutting tooth disc 122 extend into the gap between adjacent cutting teeth of cutting tooth disc 121, so as to extrude, tear and shear the solid waste or residue in water, thereby being broken, improve the passability of sewage in water in pipeline and suction pump body, and play the role of anti-clogging.
[0030] Further, the main body 1 further comprises an auxiliary feeding device 14 arranged in the main frame 11 and located at the side of the input port 111, for feeding solid garbage or sludge in water into the occlusion 13 between the cutting tooth discs 121 and 122. Since the solid garbage or sludge is mixed in water, it is difficult to enter the occlusion 13 only by the power of water flow. By means of the pushing and extruding force of the auxiliary feeding device 14, the solid garbage or sludge can be pushed and extruded into the occlusion 13, greatly improving the efficiency of the crushing and cutting and avoiding the problem of accumulation.
[0031] Further, the auxiliary feeding device 14 comprises a plurality of cam dials 141 arranged at intervals along the axial direction. The power of the power part 2 is transmitted to the rotating shaft of the auxiliary feeding device 14 through the power distribution box, and the cam dials 141 can rotate along the rotating shaft, thereby extruding and pushing the solid garbage or sludge in water into the occlusion 13 between the cutting tooth discs 121 and 122, facilitating the crushing and cutting. As an optional embodiment, the power of the auxiliary feeding device 14 can also come directly from the power motor.

A rotating drum grid 15 is arranged at the gap position, and the rotating drum grid 15 is provided with a gap 151 through which water flows. The power distribution box transmits power from the power part to the rotating shaft of the rotating drum grid 15 to rotate the rotating drum grid 15, so that the solid waste or slag can be smoothly introduced into the occlusion 13, avoiding the formation of dead angle area and the problem of accumulation. The gap 151 of the rotating grid 15 ensures stable suction flow area, prevents the suction capacity of the suction pump from being affected by insufficient water flow, and the high-speed rotation of the rotating grid 15 also realizes high-speed self-cleaning.
[0038] As an optional embodiment, the power of the rotating drum grid 15 can also be separately matched with a power motor.
[0039] Preferably, the above-mentioned gap is less than or equal to the diameter of the rotating drum grid 15.

For various objects such as ropes and cloth pieces that are prone to entanglement, the occlusion cutting disc 121 and 122 can effectively cut and shred the corresponding objects. During the rotation of the cutting disc 121 and 122, the side grid 16 has the effect of cleaning the gap between the cutting disc 121 and 122.
[0042] Further, at least one conversion joint 31 and 32 is further included for connecting the input port 111 and / or the output port 112.
