Earth-moving machine loosening mechanism - has buckets and shutters in wheel extending to central shaft

摘要

The loosening mechanism is for an earth-moving machine, having a bucket wheel (25) with rear shutters (5) hinging on the buckets (4) at the outside end. These swing inwards in the digging position and outwards to unload under control of a guide (7), their inner ends (17) being guided along the front of the following buckets. The buckets and shutters are so arranged that their inner ends extend to the central shaft (1) of the wheel. There can be a spoil-conveyor alongside the wheel, receiving it from the buckets. ADVANTAGE - Light weight and high capacity.
