Abstract
A baler for forming round bales of crops, includes: a frame providing an internal volume; a plurality of guide rollers placed inside the internal volume; a plurality of belts placed side by side in the internal volume and wound around the guide rollers so to define an endless loop; a belt divider to divide each belt of the plurality of belts from the adjacent one, wherein each belt of the plurality of belts lays in a plane which is oriented longitudinally so that the plurality of belts, when stretched between the plurality of rollers, are oriented along a longitudinal direction and wherein at least a part of the belt divider is movable in a direction parallel and transversal to the longitudinal direction.

A baler for forming round bales of crops, including
- a frame providing an internal volume;
- a pick up unit attached to the frame and configured for picking up crops from the ground and for feeding it into the baler, the feeding unit having an inlet facing the ground and an outlet facing the internal volume;
- a compression chamber for compressing the crops to form the bale, the compression chamber being of a variable diameter, wherein the crops is fed to the compression chamber from the outlet of the feeding unit in a feeding direction;
- a plurality of guide rollers placed inside the internal volume and including a pair of entrance rollers;
- a plurality of belts placed side by side in the internal volume and wound around the guide rollers so to define an endless loop, the loop being flexible for delimiting the compression chamber, wherein the guide rollers are rotatable for driving the belts around the loop,
- wherein the baler further comprises a belt divider to divide each belt of the plurality of belts from the adjacent one, the belt divider having divisions corresponding in number to the number of the plurality of belts, wherein each belt of the plurality of belts lays in a plane which is oriented longitudinally so that the plurality of belts, when stretched between the plurality of rollers, are oriented along a longitudinal direction, wherein at least a part of the belt divider is movable in a direction parallel and transversal to the longitudinal direction.
A method for forming round bales, comprising the following steps:
- providing a baler with a plurality of guide rollers placed inside an internal volume of the baler and including a pair of entrance rollers;
- placing a plurality of belts side by side in the internal volume and wind them around the guide rollers so to define an endless loop, the loop being flexible for delimiting a compression chamber;
- rotating the guide rollers for driving the belts around the loop;
- feeding the crops into the compression chamber of the baler through a pick up unit in a feeding direction,
- compressing the crops to form the bale in the compression chamber;
- dividing each belt of the plurality of belts from the adjacent one through a belt divider, the belt divider having divisions corresponding in number to the number of the plurality of belts;
- placing each belt of the plurality of belts in a plane which is oriented longitudinally so that the plurality of belts, when stretched between the plurality of rollers, are oriented along a longitudinal direction,
- characterized in that at least a part of the belt divider is movable in a direction parallel and transversal to the longitudinal direction.
