Background The feeding device is a key link for uniformly and quantitatively conveying bulk materials from a storage bin to downstream equipment in industrial production, and is widely applied to industries such as mines, metallurgy, building materials, chemical industry and the like. Along with the development of production diversification, one production line is often required to process materials from various sources and batches, and the materials have obvious differences in granularity (from massive ore to fine powder), moisture content and viscosity (from dry particles to wet mud), density and polishing property (from light grain to high-density ore) and the like, so that high requirements are put on the adaptability of a feeding device. The main stream feeding mode at present mainly comprises three modes, namely 1) a screw feeder which is suitable for powdery and small-particle materials, but is easy to block when being used for processing viscous materials, is fast in abrasion of processed polished materials and is easy to wind and block when meeting fiber impurities, 2) a belt feeder which is stable in operation and low in breaking rate, but is not resistant to large sharp materials, is not resistant to high temperature, and is easy to cause return belt materials and deviation when being used for viscous materials, and 3) a vibrating feeder which is simple in structure and resistant to high temperature, can be used for processing large materials, is easy to block when being used for wetting viscous materials, is easy to block when being used for sticking grooves, is also easy to secondarily break fragile materials when being used for dust control when being vibrated at high frequency. Aiming at the problems, the method for adjusting exciting force, adding anti-blocking structures and the like is adopted at present, but the method is mainly applicable to single material working conditions, and when the material types are frequently switched, self-adaptive adjustment cannot be realized.
