Bale collector with rollers

Bale collector, comprising a frame provided with wheels, bale carrying means, coupling means which are suitable for coupling the frame to a mobile baler in order to receive bales onto the carrying means from a bale outlet of the baler via a front end, viewed in the direction of travel of the carrying means, and also control means for taking the carrying means into a collecting state or into an unloading state, for collecting bales on the carrying means or unloading bales from the carrying means and depositing them on the ground, the carrying means comprising rollers with parallel horizontal axes, and the rollers being suitable for collecting a row of two or more bales thereon between the front end and a rear end of the carrying means, wherein the rollers form a two-part bottom which can be moved from beneath bales collected thereon, each bottom part being fixed to a corresponding sub-frame which is coupled by way of corresponding rotary means to the frame, while the axes of rotation of the rotary means extend horizontally and parallel to the direction of travel at a distance from each other which is greater than a dimension of the row of bales in a direction at right angles to the direction of travel, and for reaching the unloading state from the collecting state the control means control the rotary means for tuning the bottom parts in order to allow the row of bales to go through between the bottom parts and to be deposited on the ground.
