PURPOSE:To realize formation of a small and simple portable conveyor easily changeable in a direction of conveyance by fitting a horizontally rotatable receiving conveyor and a feed conveyor around a common support shaft on a movable machine underframe. CONSTITUTION:A fulcrum shaft cylinder 5 is upwardly provided in the center of a freely movable machine underframe 1, and a base end part of a swivelling arm frame 2 is fitted to said cylinder 5 by means of a pivot. The fulcrum shaft, supported so as to freely turn in the fulcrum shaft cylinder 5, is fitted with a base part of a receiving conveyor 3 on its upper end, while a feed conveyor 4 and conveyance rollers 8, supported by means of a horizontal arm frame 7, are provided on a free end side of a swivelling arm frame 2. A rail annulation 9 is laid round an axis of the fulcrum shaft cylinder 5 on the surface of the machine underframe 1, and support rollers 10 rolling on said annulation 9 are provided on the swivelling arm frame 2 and the receiving conveyor 3 respectively. Thus, the receiving conveyor 3 and the feed conveyor 4 are made capable of freely setting their directions with respect to carrying in and out conveyors 23, 24 arranged with any angles. |
