Rolling device, in particular for placing bulk materials on the ground

A rolling device for depositing bulk materials on the ground in the form of a bed, the rolling device including a rolling chassis equipped with a reservoir for storing and distributing bulk materials and a smoothing table, the smoothing table having a leading edge arranged along the width of the device, transversely to the direction of movement of the device, and the reservoir being provided, in the lower part forming the bottom of the reservoir, with a discharge opening arranged between the leading edge of the smoothing table and the wheels of the rolling chassis of the device, in order to deposit a bed of bulk material with a controlled thickness, wherein the rolling chassis is mounted so as to be able to tilt around a rotation axis of the wheels by which the rolling chassis rests on the ground in order for the device to go from a so-called working configuration in which the smoothing table is in bearing contact with the ground to a so-called transport configuration, in which the smoothing table is separated from the ground, wherein that the wheels of the rolling chassis are driving wheels, and wherein the reservoir and the smoothing table form a movable assembly, the position of the movable assembly being adjustable via adjusting means configured to allow, at least in the position in which the wheels of the rolling chassis rest on a horizontal flat ground and the smoothing table extends parallel to the ground, separated from the ground, on the one hand, an adjustment of the height of the smoothing table and the discharge opening by raising, respectively lowering the assembly so as to move the assembly further from the ground, respectively closer to the ground, and on the other hand an adjustment of the incline of the smoothing table so as to form a non-nil angle between the plane of the smoothing table and the rotation axis of the wheels.
