Mobile device for continuous cleaning of granular materials

摘要

The mobile cleaning device for granular materials esp. sand consists of a crawler tool (3), a supporting frame (5) and a production unit (1). On both sides of the machine direction there is a continuously adjustable hydraulic drive (18) of the production unit through which the cleaned material is grabbed from the floor and put through a vibrating serve. The conveyor band (19) may have conveyor shovels (15) stuck to it and the turning angle, gamma, of the conveying shovels may be between (50) and (90) degrees and the floor edge may deviate between 0.5 and 2 cm. The propulsion roller (13) may be a shaft with a rubber or a plastics ring (21).
