Concrete slab joint filling equipment - has conveyor transporting slabs through raking, smoothing, brushing and cleaning stations

摘要

The equipment fills in the joints between concrete pavement or roadway slabs covered on one side with ceramic material etc. A conveyor (2-5) continuously transports the slabs in the longitudinal direction, and has a sequential arrangement of loading (7) and selection (8) stations, and trowelling stations (9,9') for soft and solid mortar. Then follow smoothing stations (11,12), using cement and quartz sand, and finally brushing stations (13,14). Edge cleaning stations (16,17) have a slab-inverting mechanism between them, and a further brushing station (20) is followed by a discharge station (22).
