Detailed Description
The technical scheme of the utility model is further explained by combining the drawings and the embodiment.
The novel center transmission mud scraper comprises a working bridge 4 arranged at the top of a pool 1 in a crossing mode, and a driving assembly is arranged in the middle of the working bridge 4. The driving assembly comprises a speed reducing motor 5, the speed reducing motor 5 drives the skimming assembly to rotate through a rotating main shaft 6, and the skimming assembly cleans sludge at the bottom of the water tank 1 to the sludge discharge pit. The mud discharging pit is communicated with a mud discharging pipeline 10 for discharging the mud in the mud discharging pit.
The skimming element comprises a crossed main boom 13 and an auxiliary boom 12, which are tensioned by a tie rod 3, and the main boom 13 is also connected to the rotating main shaft 6 by the tie rod 3. The main cantilever 13 is arranged parallel to the bottom of the tank, and the angle between the main cantilever 13 and the main rotating shaft 6 is 86.4 degrees. The main cantilever 13 is provided with eight oblique-crossing mud scrapers 9 along the length direction, and the oblique-crossing mud scrapers 9 have good continuity and high mud collection efficiency. The oblique crossing type mud scraper 9 comprises a stainless steel bottom plate 16 and a rubber plate 15, and the bottom end of the rubber plate 15 protrudes out of the bottom end of the stainless steel bottom plate 16, so that mud scraping is thorough and clean, and mud floating is avoided.
