CONTINUOUS VERTICAL CONVEYOR DEVICE

PURPOSE:To eliminate the fear of residual material slipping down from the inside of an empty container so as to improve reliability by providing the empty container descending path part of a vertical path with a container position control means disposed abreast so as to keep the conveyor container in the horizontally erected position in a continuous vertical conveyor device having a Z-shape circulating path. CONSTITUTION:At the time of conveying sediment, dug in underground digging work or the like, onto the ground, conveyor containers 4... are suspended oscillatingly around horizontal supporting shafts 23a, 23b in relation to a pair of driving chains and moved circularly along a Z-shape circulating path. At the time of moving in a discharge part reaching a lower horizontal path part 3c from a tip turn part, the container 4 is put in a horizontally turned-over position from a horizontally erected position through a vertical position so as to discharge the sediment. The container 4 is then rotated again while being kept in the horizontally erected position and approaches as it is the descending path part 2b of a vertical path 2. At this time, the guide rails 25A, 26A of a container position control means 31 come in contact with the inside of guide rollers 19a-20b, so that the container 4 is guided downward while being kept in the horizontally position.
