Vehicle discharge system

A vehicle comprising a system for discharging material from a vehicle, said system comprising

• a material holding container mounted on said vehicle,
• a first material transport means, arranged under said material holding container, to transport material from said material holding container, said first material transport means being propelled by a first propulsion means,
• a second material transport means, arranged adjacent said first material transport means and comprising a conveyor having a second endless belt with an upper surface to receive material from said first material transport means and to deliver material from said first material transport means to a desired location remote from said vehicle, said second endless belt being propelled by a second propulsion means,
• a material hold-down means arranged and held on said second material transport means by supports, movable between a raised position and a lowered position by being manipulated by at least one swivel arm, to bias material securely onto said upper belt surface of said second material transport means, in the lowered position, until the material has been accelerated up to a travel speed of said second material transport means, wherein said material hold-down means has a first wheel shaft with a first wheel and a second wheel, a second wheel shaft with a third wheel and a third endless belt running from said first wheel shaft to said second wheel shaft and resting upon said first wheel, said second wheel and said third wheel, said first and second wheel shafts being mounted on a frame means, and where said third wheel is arranged substantially centred on said second wheel shaft and said first wheel and said second wheel are substantially equidistant from the centre of said first wheel shaft, said frame means being securely mountable on said second material transport means and said at least one swivel arm pivotably connected at one end of said at least one swivel arm to said support and at an opposite end of said at least one swivel arm to said frame means of the material hold down means so that, when said material hold-down means is in said lowered position, said third endless belt of said material hold-down means is propelled by frictional forces between said third endless belt and said second endless belt of said second material transport means, so that said third endless belt tends to be self-tracking when it is propelled by said second endless belt of said second material transport means.
