The traveling mud scraper is suitable for advective sedimentation tanks in water supply and drainage projects. The scum scraper can be set according to the user's requirements. According to the direction of water flow, it can be divided into reverse mud scraping and reverse slag discharge and reverse mud scraping and slag discharge in the same direction. When the mud scraping mechanism does not scrape the mud, the mud scraping rake is fully lifted. When returning to the starting position of scraping the mud, the scraping rake falls down, and the work goes round and round.

Structure and working principle
The driving type mud scraper is mainly composed of a transmission device, a driven shaft device, a driving shaft device, an adjustment device device, a bracket, an electric control box and other components.

The main structure
(1) The transmission device is installed at the travel wheel bracket, and consists of an asynchronous induction motor, a cycloidal pinwheel reducer, a gear and a machine base. The transmission device has high transmission efficiency, large torque, stable operation and low noise. A safety shear pin is arranged in the sprocket of the output shaft of the reducer, so as to realize the function of mechanical overload protection. The motor deceleration device has sufficient output torque, its rated torque is greater than 1.25 times of the scraping torque of the scraper, and the upper and lower adjustment mechanism of the scraper and the bottom of the pool is set to control the distance between the scraper and the bottom of the pool. The adjustment range is 0-50mm.
(2) After the transmission device is installed, it is not adjusted up and down, and it is mainly driven by the transmission gear, and the gear engagement gap is required to be compact and even without noise.
(3) The mud scraper [1] and the traveling motor are required to not interfere with each other during operation, and their respective operations do not interfere with each other.
(4) There are oil injection holes in each lubricating part.

working principle
The mud scraper and the traveling motor perform their own duties in operation without interfering with each other. The bottom of the mud scraper is equipped with an underwater traveling wheel structure to ensure smooth operation. The two traveling motors use synchronous motors to ensure the walking on both sides. Consistently stable.
