ABSTRACT:
An agricultural baler (1) having a duct (26) for the transportation of crop material to a bale case (10), wherein it is compressed into bales. Above the duct (26) is provided a loading device comprising a pair of cyclically rotating cranks (74), pivotably connected to a pair of levers (72) of a stuffing fork assembly (66). During operation the levers (72) are moved along journals (88) which fit in oblong slots (90) of said levers (72). The journals (88) are installed on pivotable members (94) which are forced upwardly in a first position against stop members (98, 100) by springs (99). Upon rotation of the cranks (74) the tines (70) of the fork follow a generally kidney-shaped path (92). When the tines enter the duct (26), the pivot members (94) are forced downwardly to a second position by the abutment of the journals (88) against plugs (106) in the slots (90), whereafter they are force upwardly by the cam member (102) of the cranks (74). The proper dimensioning and location of plugs (106) and pivot members (94) allows a substantial reduction of the peak speed of the tines (70) during the stuffing of the bale case (10). The forces applied by the crop material to the stuffer mechanism are reduced accordingly.
