Mine three continuous rollers
Mining triple rollers often have inflexible operation during work, and are not resistant to impact and have a short service life. The utility model has a simple structure. One universal joint is connected to each end of the bottom roller, and the two side rollers are integrated with each other through a spring shaft. The side roller and the supporting roller frame are connected by a suspended floating bearing box. The utility model replaces the original six bearings with two bearings, which not only reduces costs but also reduces power consumption. The use of a spring shaft improves impact resistance and extends service life.
