[0019] Example 1

[0020] like Figure 1 and Figure 2As shown, a cantilever truss scraper includes a truss 1, a fixed drum 2, a slag remover 3, a scraper blade 4 and a central cylinder 5. The fixed drum 2 is connected to the truss 1 through a driving assembly, the central cylinder 5 is connected to the top of the fixed drum 2, the slag remover 3 is connected to the central cylinder 5, and the slag remover 3 is in communication with the central cylinder 5; the scraper blade 4 is connected to the fixed drum 2, and the scraper blade 4 is located below the slag remover 3. The slag remover 3 has a cavity, and the slag remover 3 is connected to the central cylinder 5 through a rotating assembly, and the slag remover 3 sends the floating slag into the central cylinder 5. A slag external discharge receiving bucket 6 is provided on the top of the central cylinder 5, and the slag external discharge receiving bucket 6 can better receive floccules and prevent the floccules from leaking out. The slag remover 3 is driven by the rotating assembly, and the slag remover 3 collects the floccules floating on the water surface into the slag remover 3 during the rotation process, and then sends them to the central cylinder 5, and finally the floccules are transported to the first mud discharge pipe 7 through the central cylinder 5. The scraper 4 collects the sludge at the bottom and finally discharges it, thereby achieving the purpose of cleaning the floccules on the sewage surface and the sludge at the bottom of the sewage at the same time, improving the work efficiency and ensuring the degree of purification of the sewage.

[0021] The central tube 5 is provided with a first cantilever 8 and a second cantilever 9, the outer side of the scraper blade 4 is connected to the central tube 5 via the first cantilever 8, and the inner side of the scraper blade 4 is connected to the central tube 5 via the second cantilever 9, and a mud-catching plate 11 is arranged at the bottom of the scraper blade 4.
