Device for picking up forage bales from the ground and self-loading forage bale machine comprising this device

A device for picking up bales of forage on the ground comprising a frame capable of being coupled to a self-loading forage bale machine, the device comprising:

• a first bale traction unit and a dragging mechanism of said first bale traction unit mounted on a first chassis of the frame in such a way as to define a first upward stretch;
• and
• a second bale traction unit and a dragging mechanism of said second bale traction unit mounted on a second chassis of the frame in such a way as to define a second upward stretch coming from the first upward stretch,
• wherein:
• the first chassis is configured to articulately attach in a rotating manner to the second chassis, so that it is capable of rotating around a rotating axis due to an impact force of a bale, from an extended initial position to a retracted position intended to bring the first bale traction unit closer to the ground in order to maximise contact with bales on the ground,
• the device comprises a damper assembly configured to compensate on the first chassis an effect of the impact force of the bale, and to actuate a return to the extended initial position when the impact force ceases, and
• said first chassis comprises a plurality of sub-chassis on which is distributed the first bale traction unit, and wherein said plurality of sub-chassis are attached in a rotating way to the second chassis so that each one of the plurality of sub-chassis is configured to rotate independently around its respective pivoting axis, from the extended initial position to the retracted position.
