1,164,702. Conveyers for unloading. CRONE & TAYLOR (ENG.) Ltd. 29 April, 1968 [12 May, 1967], No. 22225/67. Heading B8A. Material in a coal or like wagon is discharged, via bottom doors 17, 18 on to vibratory pans 15, 16 which are mounted on a carriage 10. This is power-driven or moved by a pressure fluid so that the carriage can be traversed and a section of rail track 14 aligned with rails 13 of a railway siding. A wagon is run along the rails 13 until its wheels straddle the carriage 10 which is then moved to the position shown in full lines. Material discharges with little or no free fall on to the pans 15, 16 before passing on to a belt conveyer 19. The carriage 10 having been traversed to the position shown in dotted lines, the empty wagon is able to continue along the rails 13 and a further wagon moved up for discharging. The discharge procedure may be automated by means of level indicators or weight sensitive devices. In Fig. 3, an intermediate conveyer 20 connects vibratory pans 15, 16, mounted in line with the rails 13, with the conveyer 19. In Fig. 6, a vibratory or belt type conveyer 21 is in a fixed position between the rails 13 and spill or guide plates 22 are provided. When the conveyer is vibratory flexible strips 23 seal the gap between the rails and the conveyer. The latter discharges on to a belt conveyer 24. There may be two vibratory conveyers 21 to permit simultaneous discharge into conveyer 24. Material from conveyers 19 or 24 may be transferred by an adjustable loader (27) into hoppers (28), Fig. 7 (not shown). |
