Abstract: 862,956. Earth excavators. ROEMERT, E., and VENTER, H. Oct. 4, 1957, No. 31147/57. Class 68(1). In a travelling plant for loosening picking up and loading surplus material on the'side of a rail track in which a scarifier and a bucket elevator are arranged on one longitudinal side of a platform truck running on the rail track and on which truck cross and longitudinal conveying devices are provided the bucket elevator is supported by a structure capable of being swung into a longitudinally directed horizontal position in known manner above the platform truck within the prescribed clearance profile for travelling and arranged so that it can run out laterally of the platform truck by means of transversely adjustable and fixable carrier girders, the scarifier is adjustable in height on transversely adjustable and fixable carrier girders and can swivel in a vertical plane and a cross-conveyer belt is provided as a cross-conveying device and is mounted on carrier girders adjustable transversely relative to the longitudinal axis of the truck and fixable and is capable of being turned about a vertical axis. The bucket elevator 7, adjustable in height by a rack 6 driven by an electric motor through a worm gear 28 and pinion 29, is mounted on a flange 8 so as to be capable of being swung in a vertical direction parallel to the platform truck 1. The bucket elevator 7 and the height adjusting device are mounted on an arm 31 so to be given the inclination of the side way or to be swung, after being pivoted on the flange 8, to a horizontal position above the level of the platform truck 1 when it is then moved transversely, to the dot-dash position shown in Fig. 5, on two girders 3 driven by an electric motor 28 and worm 4 and guided on a guide bed and held in position by fixing devices 23. The arm 31 can be attached to setting segments 32 provided with a series of holes 33 to hold the arm 31 in the desired position. The bucket elevator 7 when in the horizontal position shown in Fig. 5 lies within the travelling profile 34. The upper end of the bucket elevator 7 is located above a hopper 10 which feeds the conveyer belt 11 arranged at right angles to the longitudinal direction of the platform truck 1. The conveyer belt 11 feeds one or more.conveyer belts 12, Fig. 1, supported by frames 13 mounted on loading trucks 14 coupled to the platform truck 1 and fitted with scrapers or strippers 15 which uniformly distribute the load over the trucks 14. The platform truck 1 is driven forward by a separate driving arrangement on the truck I or by a capstan or a tractor travelling on the rail track. The scarifier 17, Fig. 7, arranged in the front of the bucket elevator 7 is pivotally mounted, so that it can turn about a vertical plane, on an axle 19 carried on an "1" girder 16. The girder 16 is arranged so that it can be moved laterally to the longitudinal axis of the platform truck and held in the adjusted position by a fixing device 23. The scarifier, which can be adjusted in height by a rack 40, pinion 41 and a worm 42 which can be driven by hand or an electric motor 43, is held in the operative position by a pull element 20 extending forwardly and laterally and provided with a safety device 21 which will brake in the event of the fork 18 of the scarifier 17 striking a heavy obstacle. The fork 18 is mounted on a flange 44 so that it can be turned through 90 degrees thus enabling the scarifier to be drawn, as shown in dot-dash lines Fig. 7, within the travelling clearance profile 34. A pair of guide blades 22 pivotally mounted on side cheeks 35 on the bucket elevator supporting structure extends forwardly to the scarifier forks 18 to guide the, bedding material 9 on to the bucket elevator 7, The guide blades 22 are attached to the lower end of the scarifier 17 by pull elements 36 which can be adjusted to vary the angle of the guide blades 22 one with the other. The cross conveyer belt frame structure is mounted on "I" girders 26 which are transversely adjustable and fixable similar to that previously described for the elevator bucket 7. The cross conveyer I is pivotally and fixable about a vertical axis by means of a flange connection 37 carried by a parallelogram link system 38 provided with a screw tensioning stay 39. The arrangement is such that the cross conveyer 11 can be swung to a position parallel to the longitudinal axis of the truck 1 and moved by means of the girders 26 and the link system 39 to the position shown in dotdash lines in Fig. 6 beside the bucket elevator 7 and within the travelling profile 34. The drive for the bucket elevator 7, cross conveyer I and the conveyer belt or belts 12 can be derived from a diesel-electric unit on the platform truck 1.
