[0023] The crushing mechanism 7 includes a rotating column 71, a supporting ring body 72, a fixed sleeve 73, a cutting blade 74, a driving assembly 75 and a base assembly 76. The base assembly 76 is fixedly installed inside the frame 1, and two rotating columns 71 are rotatably installed inside the base assembly 76, and the supporting ring bodies 72 on the surfaces of the two rotating columns 71 are located at the top of the base assembly 76, and the surface of the rotating column 71 is fixedly installed with a fixed sleeve 73 by bolts, and the surface of the fixed sleeve 73 is fixedly installed with three cutting blades 74, and the top of the top plate 3 is provided with a driving assembly 75 for rotating the rotating column 71.

[0024] The driving assembly 75 includes a second motor 751, an output convex shaft 752 and an insertion groove 753. Two second motors 751 are fixedly installed on the top of the top plate 3. The output ends of the two second motors 751 both penetrate the bottom of the top plate 3 and are fixedly installed with the output convex shaft 752. The tops of the two rotating columns 71 are both provided with an insertion groove 753 adapted to the output convex shaft 752.

[0025] In this embodiment, starting the second motor 751 drives the output cam 752 to rotate, and the output cam 752 is engaged with the insertion groove 753 at the top of the rotating column 71. When the output cam 752 rotates, it can drive the rotation adjustment of the rotating column 71, and the two second motors 751 may not be synchronous motors, and the convex portion on the surface of the output cam 752 is adapted to the insertion groove 753.

[0026] In order to enhance the stability of the rotating column 71 during rotation, a protective sleeve 9 is movably sleeved on the surface of the rotating column 71 to make the rotating column 71 rotate more stably. The tops of the two rotating columns 71 are movably sleeved with a protective sleeve 9, and the tops of the two protective sleeves 9 are fixedly mounted on the bottom of the top plate 3.

The particles in the crushed sludge are smaller, which extends the service life of the sewage suction pump 81. The design of the sewage suction pump 81 enables it to discharge various solid and long-fiber impurities without clogging it.

[0031] Since the first motor 6 is in a relatively humid working environment, which may easily lead to a shortened lifespan, a sealing shield 10 is provided to provide better sealing protection for the first motor 6 . A sealing shield 10 for protecting the first motor 6 is installed on the frame 1 .

Two handles are fixedly installed on the top of the top plate 3, and the tops of the four guide rods 2 are all threadedly installed with limit nuts 11.

[0033] The device starts the first motor 6 to drive the rotating roller 4 to rotate, and then drives the digging shovel 5 to dig the sludge in the river channel into the frame 1, and starts the second motor 751 to drive the output cam 752 to rotate, so that the rotating column 71 drives the surface cutting blade 74 to rotate, and the large particles of debris in the sludge are fully crushed. The crushed sludge will be concentrated at the bottom of the frame 1, and the treated sludge will be discharged through the conveying pipe 82 by using the sewage suction pump 81. When disassembling and maintaining the rotating roller 4, the limit nut 11 is removed from the guide rod 2, and the top plate 3 is lifted by the handle, so that the output cam 752 at the output end of the first motor 6 is disengaged from the insertion groove 753, and the rotating column 71 is pulled out from the supporting sleeve 762, so as to take out the rotating column 71, and the bolts on the fixing sleeve 73 can also be removed to replace the cutting blade 74.
