Abstract
An agricultural baler has a plunger for compressing harvested material to a bale in a chamber, a crank mechanism connected to the plunger for the purpose of driving the plunger, wherein the crank mechanism comprises at least one first crank and at least one second crank, a drive mechanism for driving the first crank and the second crank, wherein the drive mechanism is configured such that, when the first and second crank are driven, the first crank and the second crank rotate in opposite directions.
Claims14
An agricultural baler, comprising:
- a plunger for compressing harvested material to a bale in a chamber;
- a crank mechanism connected to the plunger for the purpose of driving the plunger, the crank mechanism comprises:
- at least one first crank and at least one second crank and a drive mechanism for driving the first crank and the second crank;
- the drive mechanism comprises, a first drive line for driving the first crank and a second drive line for driving the second crank, the first drive line comprises a first toothed wheel and the second drive line comprises a second toothed wheel;
- wherein the drive mechanism is configured such that, when the first and second crank are driven, the first crank rotates in a first direction and the second crank simultaneously rotates in a second direction, the first direction opposite from the second direction;
- wherein the first drive line and the second drive line being coupled for simultaneous driving of the first crank and the second crank;
- wherein the first toothed wheel and the second toothed wheel are both in engagement with a coupling toothed wheel for a simultaneous driving of the first crank and the second crank;
- and
- wherein at least one of the first toothed wheel, the second toothed wheel and the coupling toothed wheel is a bevel wheel.
