The energy-saving cleaner is a rotating brush cleaner, powered by an angled roller, and does not require an additional power source. It has the characteristics of almost no wear to the belt, good cleaning effect, long service life, high economic efficiency, safety and reliability. Not only can it have a good environmental protection effect, but more importantly, it reduces the labor intensity of workers and prolongs the service life of the belt. Through the trial on the installed machine, compared with the ordinary cleaner, it is found that it has the following advantages: 1. The cleaning and mud cleaning effect is obvious, which greatly reduces the labor intensity, and at the same time, the reversing drum has no mud adhesion, which reduces the bulging factor of the belt joint; 2. The original H Type P cleaner, once damaged, it will scratch the belt, or tear the belt if it is damaged. The new cleaner uses polyester fiber to clean the material and the belt wear is negligible, safe and reliable, and can greatly improve the service life of the belt. 3. The cleaner is externally installed in the unloading bin, which is convenient and safe to replace and maintain. 4. Long service life. Compared with ordinary cleaners, the service life of this cleaner is 12-15 months, and ordinary cleaners are generally one to three months. 5. The new energy-saving cleaner has low cost and high cost performance.
