PCT No. PCT/GB94/02800 Sec. 371 Date Jun. 12, 1996 Sec. 102(e) Date Jun. 12, 1996 PCT Filed Dec. 20, 1994 PCT Pub. No. WO95/17318 PCT Pub. Date Jun. 29, 1995A vehicle discharge system for a vehicle (1) provided with a rearwardly tippable bed (2) which includes a tailgate (3) is constituted by a housing (5) mounted at the rear of the bed (2) adjacent to the tailgate (3), a discharge auger (4) rotatably supported within the housing (5) and arranged to receive material which passes the tailgate (3) when the bed is tipped, an auger drive (9) to drive the auger and discharge material carried within the vehicle bed (2) to the side of the vehicle (1) as the bed is tipped and flow control structure (1) capable of differentially exposing material held within the vehicle bed (2) to the discharge auger (4). The flow control structure is constituted by a flow control gate (1) which is capable of being moved in a plane substantially perpendicular to the plane of the base of the vehicle bed (2) and tilted to form a tapered and adjustable opening which exposes material within the vehicle bed to the auger as the bed is tipped. The nature of an auger is to preferentially pick up material from one end remote from that at which material is discharged and so the flow control gate is tilted to expose less of the auger to the material at that end. The combination of varying the opening height and degree of tilt of the flow control gate ensures that material is discharged evenly and controllably across the width of the vehicle bed. |
