Abstract
An agricultural device is movable in a direction of advance and includes: a cutter bar equipped with cutting elements intended to cut a standing crop product; a conditioner positioned behind the cutter bar; and a grouping device intended to move the product transversely to the direction of advance and located behind the cutter bar, in an active position. A retraction actuator is configured to transpose the grouping device between the active position and a passive position in which the product is deposited at the rear of the device. A collecting device extends partially under and partially behind the conditioner in active position of the grouping device.
Claims13
An agricultural device being movable in a direction of advance and comprising:
- a cutter bar equipped with cutting elements intended to cut a standing crop product,
- a conditioner positioned behind the cutter bar, and
- a grouping device intended to move the product transversely to the direction of advance and located, in an active position, behind the cutter bar,
- a retraction actuator being configured to transpose the grouping device between the active position and a passive position in which the product is deposited at a rear of the grouping device, and
- a collecting device which extends, in the active position of the grouping device,
- partially under and partially behind the conditioner,
- wherein a movable part of the collecting device is fastened to the grouping device, and
- wherein in the active position of the grouping device, the collecting device and the cutter bar are adjacent to each other,
- wherein in the active position of the grouping device, the collecting device extends from the cutter bar to the grouping device along the direction of advance,
- wherein the conditioner comprises a drum driven in rotation around a rotation axis forming a path, and
- wherein the movable part covers, in the active position, an angular sector of at least one eighth of the path, viewed along the rotation axis.
A method providing access between a conditioner and a grouping device belonging to an agricultural device, the agricultural device being movable in a direction of advance and including a cutter bar equipped with cutting elements intended to cut a standing crop product, the conditioner being positioned behind the cutter bar, and the grouping device being intended to move the crop transversely to the direction of advance, the grouping device being transposable between an active position and a passive position, wherein at least one movable part of a collecting device is fastened to the grouping device and is located partially under and partially behind the conditioner in the active position, the method comprising:
- transposing the grouping device by a retraction actuator between the active position and the passive position,
- wherein in the active position of the grouping device, the collecting device and the cutter bar are adjacent to each other,
- wherein in the active position of the grouping device, the collecting device extends from the cutter bar to the grouping device along the direction of advance,
- wherein the conditioner comprises a drum driven in rotation around a rotation axis forming a path, and
- wherein the movable part covers, in the active position, an angular sector of at least one eighth of the path, viewed along the rotation axis.
