Abstract: A tubular structure of rectangular plant arranged mounted on the distal end of both pairs of rotating arms (13/14) (15/16) that extend backwards from a lower sector of the machine, below the tunnel (C). The rotating arms constitute a system of distorting parallelograms that define a lifting equipment capable of displacing the cradle to be arranged over the external surface of the tunnel. The pairs of rotating arms extend from respective elongated plates (8) fixed to the machine body, extending towards outside, exceeding the line of the back edge of the tunnel. From the free end of the plates there extend the pairs of rotating arms, and extend up to connecting with the curved side (6) further away from the tubular structure that constitutes the cradle, keeping the same oriented towards the machine.

Abstract: An extracting machine has a transverse roll that rolls a silage bag up as grains stored therein are extracted, to be discharged to a hopper truck. An extracting head placed in the interior of the bag has a lifting auger centrally arranged at the bottom thereof, and transverse augers extending to both sides move the grains to the lifting auger, which elevates and discharges them. A central transmission box supported at the bottom of the bag has plural output shafts extending in different directions, lying in a single vertical plane, and coupling to, respectively, the transverse augers and the lifting auger. A pusher shovel extending transversely the width of the bag has a hydraulically-adjustable transverse plate.
