General Information

BALER OPERATION

FIG. 2
FIG. 2: The illustration shows the windrowed crop being
picked up. The crop moves across the pickup assembly
(1) into the bottom of the open throat bale chamber. The
windguard (2) holds the crop against the pickup
assembly. In the bale chamber the crop contacts the
rough top surface of the forming belts (3), which are
moving upward. The forming belts carry the crop to the
top of the starting chamber which is formed by the bale
density rolls (4). The downward motion of the forming
belts turns the crop downward against the starting roll (5).
The starting roll folds the crop rearward into the crop
coming in. The core is started and begins to roll.

Springs and hydraulic cylinders pull down on the tension
arm (6). The bale density rolls are held down to reduce
the size of the bale chamber to a starting size. The belt
tension roll (7) is held down to remove the slack from the
forming belts. As the bale increases in size, the bale
density rolls are forced upward moving the bale size
indicator (8) downward. The belt tension roll puts an
increasing downward force against the belts. This force
keeps tension on the belts and compresses the crop
coming into the baler.
The stagger roll (9) holds the outside forming belts in front
of the other forming belts. This releases crop deposits
from behind the forming belts.
The forming belts are driven by the drive roll (10).
