[0030] The stirring assembly 4 includes a second connecting rod 42, both ends of which are rotatably connected to connecting shafts 45, one of the connecting shafts 45 is rotatably connected to the first connecting rod 41, the first connecting rod 41 is rotatably connected to the mounting sleeve 24, and the other connecting shaft 45 is rotatably connected to the third connecting rod 43, the other end of the third connecting rod 43 is rotatably connected to the dredging pipe 2.

[0031] Stirring blades 44 are provided on the first connecting rod 41 and the second connecting rod 42. The stirring blades 44 are distributed in a ring shape on the first connecting rod 41 and the second connecting rod 42. The stirring blades 44 increase the contact area with the sludge, thereby improving the stirring effect. Under the structural design of the stirring blades 44, when sewage flows, it contacts with the stirring blades 44 and generates thrust, so that the first connecting rod 41 and the second connecting rod 42 rotate irregularly on the third connecting rod 43, thereby improving the dredging effect.

[0032] Example 2

[0033] like Figure 2-4 As shown, a guide plate 46 is provided on the third connecting rod 43 above the guide groove 31, and there are four guide plates 46 in total, and the four guide plates 46 are distributed in a ring shape, and the angles between two adjacent guide plates 46 are equal. Through the design of the guide plates 46, when the motor drives the third connecting rod 43 to rotate, under the action of the guide plates 46, the sewage above the connecting pipe 3 is accelerated to be discharged downward, thereby increasing the sewage passing speed and preventing sludge from clogging the pipeline.

[0034] A driving motor 21 is provided at one end of the dredging pipe 2 located at the connecting pipe 3. The output end of the driving motor 21 passes through the dredging pipe 2 and is connected to the third connecting rod 43. The driving motor 21 provides power for the rotation of the third connecting rod 43. At this time, the third connecting rod 43 in a rotating state drives the guide plate 46 to accelerate the downward flow of sludge.

[0035] A mounting plate 22 is provided at one end of the dredging pipe 2 close to the mounting sleeve 24, and mounting holes 221 are opened on the mounting plate 22.

Through the guide groove 31 provided in the connecting pipe 3, under the action of the guide groove 31, the sewage entering the connecting pipe 3 flows downward in a vortex shape, and the auxiliary flow pushing of the guide plate 46 further improves the passing speed of the sewage.

[0037] Working principle:

[0038] like Figure 1-4 As shown, first, the dredging pipe 2 is connected to the water inlet pipe through the mounting plate 22, and then the connecting pipe 3 is connected to the input end of the sewage pump. When the sewage enters the dredging pipe 2, it contacts the stirring blade 44. Under the action of the thrust of the water flow, the stirring blade 44 is driven to rotate, so that the first connecting rod 41 and the second connecting rod 42 and the third connecting rod 43 rotate irregularly. At this time, the stirring blade 44 can not only provide power for the rotation of the first connecting rod 41 and the second connecting rod 42, but also increase the contact area with the sludge in the sewage through the stirring blade 44, so as to stir and dredge the blocked sludge. Turn on the driving motor 21, and drive the third connecting rod 43 to rotate through the driving motor 21. At this time, the sewage above the connecting pipe 3 is accelerated to be introduced into the connecting pipe 3 under the action of the guide plate 46, so as to avoid the dredging pipe 2 from having too slow a flow rate inside, resulting in sludge accumulation and blockage. The sewage in the connecting pipe 3 is spirally guided through the guide groove 31, so that the sewage flows downward in a vortex shape, further improving the circulation speed.
