A baler including a needle yoke driven via a needle coupling device including a connection member pivotally mounted around a fixed pivot axis for swinging around the fixed pivot axis. The swinging corresponds to movement of the needle yoke. The connection member is cooperative with the needle yoke by (i) a shearbolt adapted to transfer a force from the connection member to the needle yoke during a forward movement and (ii) by a protrusion, formed at one of the connection member and the needle yoke, to abut against the other one of the connection member and the needle yoke during a backward movement of the needle yoke.

Baler with needle overload protection

A knotter system for a baler includes a needle and a tucker arm for delivering a needle twine and tucker twine respectively, a twine receiver for holding the needle and the tucker twine, a billhook assembly including a billhook with a lower and an upper lip being mounted rotatably around an axis and being arranged for receiving the needle and the tucker twine, a twine finger for guiding the twine. Further, a driver is foreseen to make the billhook perform a first full rotation during the first knot forming cycle and a second full rotation during the second knot forming cycle. The knotter system is configured such that, at the end of the second knot forming cycle, a bale movement of a bale in the baler exerts a pulling force on the twines which removes the twines from the billhook.

Knotter system for a baler

Cam gear

A baler including a bale chamber; a plunger configured to compress crop material in the bale chamber in order to form a bale; a needle yoke with a plurality of needles configured to deliver twine through the bale chamber; a plurality of knotters configured to receive the twine from the plurality of needles; a bale length measurement and trigger device configured to measure the length of the bale in the bale chamber and to generate a trigger when a predetermined length is reached; a driving shaft located above the bale chamber and extending in a traverse direction of the baler; a needle coupling device between the driving shaft and the needle yoke, the needle coupling device being configured for moving the needle yoke from a rest position to a twine delivery position and back, when the bale length measurement and trigger device generates a trigger.

Agricultural baler with improved needle coupling device

A baler including a bale chamber; a plunger to compress crop material in the bale chamber to form a bale; a plurality of knotters; a needle yoke with a plurality of needles to deliver a plurality of lower strands through the bale chamber to the plurality of knotters; a tucker arm shaft carrying a plurality of tucker arms to deliver a plurality of upper strands to the plurality of knotters; a driving shaft located above the bale chamber and extending in a traverse direction of the baler; wherein the tucker arm shaft extends parallel to the driving shaft; a tucker arm coupling device to covert the rotation of the driving shaft into a rotation of the tucker arm shaft; a needle coupling device to convert a rotation of the driving shaft into a movement of the needle yoke from a rest position to a twine delivery position and back.

Needle coupling device for an agricultural baler

A rectangular baler comprising a bale chamber delimited by a plurality of walls including a movable wall section, an actuator for exerting a pressure on the movable wall section, a plunger for compressing crop material in the bale chamber, and a density control system including: a position calculating module configured to calculate a new position for the movable wall section based on an input representative for bale density of compressed crop material in the bale chamber, and a position control module configured to control the actuator to position the movable wall section in the calculated position.
