Problems solved by technology

[0004] In the actual use process, if the impurity belongs to the cloth strip with high toughness, it is difficult to cut off the single meshing cutting between the cutting edge d and the cutting strip b. If it is not cut off, the cloth strip is easy to get stuck between the cutting edge d and the cutting strip b, causing the water inlet to be blocked and affecting the water inlet

Embodiment 1

[0033] A floating cutting assembly, including a rotating shaft 1 rotated by a driving source, a cutting blade 2 docked with the end of the rotating shaft 1, and a cutting disc 4. Cutting bars 5 are arranged on the top, and the cutting bars 5 are radially distributed with the middle part of the cutting disc 4 as the center. The cutting blade 2 is provided with a cutting edge 3 near the end of the cutting disc 4. sundries.

[0034] In order to further improve the cutting effect, a movable shaft 6 is provided on the cutting blade 2, and the movable shaft 6 is slidingly sleeved on the end of the rotating shaft 1, and the movable shaft 6 and the rotating shaft 1 are coaxially arranged. A tension spring 7 is connected with the rotating shaft 1, and the tension spring 7 is used to pull the cutting blade 2 to the side away from the cutting disk 4.

[0035] A driving part 8 is provided on the rotating shaft 1, and a transmission part 11 is connected between the driving part 8 and the ...

Embodiment 2

[0042] A water pump includes the floating cutting assembly in the first embodiment, and the floating cutting assembly is installed at the water inlet of the water pump.

Abstract

The invention relates to a water pump and a floating type cutting assembly. The floating type cutting assembly comprises a rotating shaft rotated by a driving source, a cutting blade and a cutting disc in butt joint with the rotating shaft, a cutting strip is arranged on the cutting disc, a cutting edge is arranged at the end of the cutting blade, the cutting edge can mutually mesh with the cutting strip to cut sundries, a movable shaft is arranged on the cutting blade and slidably and movably connected to the end of the rotating shaft in a sleeving mode, and a tension spring is connected between the end of the movable shaft and the rotating shaft; a driving part is arranged on the rotating shaft, a transmission part is connected between the driving part and the movable shaft, and the driving part is transmitted to the transmission part in a power mode. Meshing force between the cutting strip and the cutting blade can act on different positions of cloth, even though cloth strips in thefirst meshing action position are firm and tenacious, as the cutting meshing position changes, the cloth can eventually be cut off, and compared with fixed cutting assemblies, according to the cutting effect of the water pump and the floating type cutting assembly, the cutting effect is relatively good in actual use.

Description

technical field [0001] The invention relates to the technical field of pumping equipment, in particular to a water pump and a floating cutting assembly thereof. Background technique [0002] A water pump is a machine that transports or increases liquid. [0003] In order to prevent long-fiber impurities from clogging the water pump, cutting components are also installed at the water inlet in existing water pumps, see figure 1 , the cutting assembly includes a cutting disc a, a cutting bar b is installed on the cutting disc a, and a cutting blade c is also installed on the pump shaft of the water pump. The cutting blade c is also located at the water inlet, and the cutting blade c is close to a side of the cutting disc a There is a cutting edge d on the side; the pump shaft will drive the cutting blade c to rotate circumferentially, and the cutting edge d of the cutting blade c will be attached to the cutting strip b. When impurities enter the water inlet, the cutting edge d...
