When the servo motor 302 drives the rotating shaft 303 to rotate forward, a set of No. 3 sprockets 406 drives the No. 2 one-way bearing to rotate forward, and the No. 2 one-way bearing locks a set of stirring shafts 401, so that the stirring shafts 401 rotate forward while the stirring shafts 401 drive another set of stirring shafts 401 to rotate forward synchronously through two sets of No. 2 sprockets 404 and a set of No. 2 chains 405, so that the multiple sets of stirring rods 402 drive the multiple sets of The stirring blade 403 mixes and stirs the wastewater and the flocculant in the sedimentation tank 101. After a period of rest, the servo motor 302 is reversed, and the second sprocket 404 is also reversed, so that the third sprocket 406 and the stirring shaft 401 rotate relative to each other, so that the two groups of stirring shafts 401 remain stationary, and at the same time, the first one-way bearing 304 locks the front end of the first rotating shaft 201, so that the rotating shaft 303 drives the first rotating shaft 201 to rotate through the first one-way bearing 304, so that the two groups of first chains 2 05 drives multiple groups of scraper blade assemblies to scrape the sludge at the bottom of the sedimentation tank 101. The second rotating shaft 202 drives the rotating shaft 501 to rotate through the cooperation of two groups of fourth sprocket wheels 503 and a group of fourth chains 504, so that the spiral blade 502 discharges the sludge scraped into the mud collecting tank 103 by the scraper assembly, thereby improving the discharge efficiency. When the stirring assembly is started, the mud discharge assembly and the scraper assembly are also in a static state. After the bottom end of the scraper blade body 604 contacts the bottom end of the sedimentation tank 101, it works The personnel rotate the butterfly bolt 606 with the cooperation of the fixing seat 605, so that the butterfly bolt 606 tightens and fixes the outer wall of the scraper blade body 604. When friction loss is generated between the butterfly bolt 606 and the bottom end of the sedimentation tank 101, the personnel releases the fixation of the butterfly bolt 606 on the scraper blade body 604, so that the scraper blade body 604 adjusts its length under the action of the elastic force of the spring 603, so that the bottom end of the scraper blade body 604 contacts the bottom end of the sedimentation tank 101 again.
