Truss structure of central rotating mud scraper

The truss structure of the center-rotating mud scraper. The center-driven mud scraper usually places the main beam between the central support and the poolside wheels, above the water surface, and people can walk on the main beam. The truss extends from the lower part of the main beam to the bottom of the pool, and a mud scraper is installed on the lower part. With the rotation of the whole machine, the mud scraping and mud collecting work is completed. Because the main beam of the peripheral drive scraper is above the water surface and has a large windward area, the impact of wind load on the operation of the whole machine must be considered in the design
The center drive scraper is installed between the edge of the pool and the central pier. A fixed working bridge is used not only for maintenance, but also for fixing the supports of motor reducers, etc. The large ring gear is fixed on the central pier, and is connected to the main frame. It rotates accordingly and drives the scraper arm connected to its lower part, so that the scraper installed at the lower end of the scraper arm completes the work of scraping and collecting mud. . The main frame and scraping arms of the central drive mud scraper are both in the form of trusses, which saves materials. The truss part is almost entirely in the water, and there is no large windward surface above the water surface. Therefore, the role of wind load is very small and can be ignored in the design. However, it requires strong symmetry and balance of the truss. It is generally used for diameters no larger than On the sedimentation tank, when the size is larger than 10%, a peripheral drive mud scraper that is easy to process should be considered.
