The crushing mechanism 2 includes a crushing box and a crushing knife mechanism. The crushing knife mechanism includes a secondary knife drive rod 201, a primary knife drive rod 202, secondary blades 203, primary blades 204, a secondary knife fixed end 205, a primary knife fixed end 206, a secondary knife primary knife head 207, secondary knife secondary cutting edges 208, a primary knife primary knife head 209, and primary knife secondary cutting edges 210. The secondary knife drive rod 201 and the primary knife drive rod 202 are arranged in an array and rotatably disposed inside the crushing box. One end of the secondary knife drive rod 201 and the primary knife drive rod 202 is fixedly connected to the output end of the motor inside the crushing box, and the other end is rotatably connected to the other side inside the crushing box. A number of secondary blades 203 are arranged in an array on the surface of the secondary knife drive rod 201, and a number of primary blades 204 are arranged in an array on the surface of the primary knife drive rod 202. The other side of the lift pump body 1 is fixedly connected through penetration with a water outlet pipe 3. The other side of the crushing mechanism 2 is fixedly connected through penetration with a water inlet pipe 4. One end of each of the water outlet pipe 3 and the water inlet pipe 4 is fixedly connected to a connecting flange 5. A number of fixing holes 6 are circumferentially and arrayedly penetrated through the periphery of the surface of the connecting flange 5.

[0026] During operation, the water outlet pipe 3 and the water inlet pipe 4 are respectively hermetically and fixedly connected to the sewage inlet end and the outlet end through the connecting flange 5 and the fixing holes 6. After the sewage mixed with sundries enters the inside of the crushing box through the water inlet pipe 4, at this time, the crushing knife mechanism is started, and the secondary knife drive rod 201 and the primary knife drive rod 202 start to rotate, thereby driving all the secondary blades 203 and the primary blades 204 to start rotating, and starting to crush the sundries. And at this time, when encountering sundries such as being wrapped by garbage bags and fabrics, since the secondary blades 203 and the primary blades 204 are arranged in an arc shape, the materials will be rotated and thrown off by the secondary blades 203 and the primary blades 204 without edges and corners, so as to ensure that they will not be entangled. After being crushed, the sewage mixed with sundries is transported to the water outlet pipe 3 through the lift pump body 1 and discharged, completing the phased transportation of the sewage.

[0027] Embodiment Two:

[0028] On the basis of Embodiment One, a secondary knife fixed end 205 is snap-fitted at both ends of the secondary knife drive rod 201. The two secondary knife fixed ends 205 limit and fix the inner secondary blades 203. A primary knife fixed end 206 is snap-fitted at both ends of the primary knife drive rod 202. The two primary knife fixed ends 206 limit and fix the inner primary blades 204. A number of secondary knife primary knife heads 207 are fixedly connected to the periphery of the secondary blades 203. A number of secondary knife secondary cutting edges 208 are opened at one end of each of the secondary knife primary knife heads 207. A number of primary knife primary knife heads 209 are fixedly connected to the periphery of the primary blades 204. A number of primary knife secondary cutting edges 210 are opened at one end of each of the primary knife primary knife heads 209;

[0029] When the crushing knife mechanism crushes sundries, when encountering a large area of sundries, the main knife secondary blade 210 and the secondary knife secondary blade 208 can provide a tearing effect when contacting the sundries, so as to tear sundries such as garbage bags, effectively reducing the situation of sundries such as garbage bags blocking the lifting pump, further improving the crushing effect of the device and the practicability of the device.

[0030] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the application shall be included in the protection scope of the present application.
