Abstract
An agricultural baler includes: a frame; a feeder system coupled with the frame and including: a cutting assembly coupled with the frame and including: at least one knife configured for cutting a crop material; an overload protection mechanism associated with a single one of the at least one knife and including a pivot device including an engagement device including an offset configuration; and a displacement apparatus configured for selectively forcing the at least one knife to occupy a first position and for selectively forcing the at least one knife to occupy a second position, each by way of the engagement device.
Claims17
A feeder system of an agricultural baler, the feeder system being coupled with a frame of the agricultural baler, the feeder system comprising:
- a cutting assembly coupled with the frame and including:
- at least one knife configured for cutting a crop material;
- an overload protection mechanism associated with a single one of the at least one knife and including a pivot device including an engagement device having an offset configuration, the engagement device including a slot including a first leg and a second leg, wherein the first and second legs extend in different directions;
- a displacement apparatus configured for selectively forcing the at least one knife to occupy a first position and for selectively forcing the at least one knife to occupy a second position, each by way of the engagement device;
- and
- a pivotable actuation arm having (i) a first end that is rotatably coupled to an output of the displacement apparatus and (ii) a second end that is moveably positioned within the slot.
An agricultural baler, comprising:
- a frame;
- a feeder system coupled with the frame and including:
- a cutting assembly coupled with the frame and including:
- at least one knife configured for cutting a crop material;
- an overload protection mechanism associated with a single one of the at least one knife and including a pivot device including an engagement device having an offset configuration, the engagement device including a slot including a first leg and a second leg, wherein the first and second legs extend in different directions;
- a displacement apparatus configured for selectively forcing the at least one knife to occupy a first position and for selectively forcing the at least one knife to occupy a second position, each by way of the engagement device;
- and
- a pivotable actuation arm having (i) a first end that is rotatably coupled to an output of the displacement apparatus and (ii) a second end that is moveably positioned within the slot.
A method of using an agricultural baler, the method comprising the steps of:
- providing a frame and a feeder system coupled with the frame, the feeder system including a cutting assembly coupled with the frame, the cutting assembly including (i) at least one knife configured for cutting a crop material, (ii) an overload protection mechanism associated with a single one of the at least one knife, the overload protection mechanism including a pivot device having an engagement device including an offset configuration, the engagement device including a slot including a first leg and a second leg, wherein the first and second legs extend in different directions, (iii) a displacement apparatus, and (iv) a pivotable actuation arm having (a) a first end that is rotatably coupled to an output of the displacement apparatus and (b) a second end that is moveably positioned within the slot;
- forcing selectively, by the displacement apparatus of the cutting assembly, the at least one knife to occupy a first position, by way of the engagement device;
- and
- forcing selectively, by the displacement apparatus, the at least one knife to occupy a second position, by way of the engagement device.
