| Abstract | An agricultural baler including a bale case, a plunger, a duct, and a stuffer unit, operably associated with the duct. The stuffer unit includes a fork assembly including tines, a drive mechanism acting on the fork assembly, and a clutch arrangement for selective coupling the drive mechanism to a power source of the baler. The clutch arrangement includes a selectively operable dog clutch including a driving clutch member and a driven clutch member. The driving and the driven clutch member are configured for selectively engaging each other in one direction of rotation of the driving clutch member relative to the driven clutch member. The clutch arrangement furthermore includes an overrunning clutch associated with the driving clutch member and the driven clutch member. |

| Claim | An agricultural baler comprising: a bale case comprising a wall portion having an entrance opening for introduction of crop material; a plunger disposed for movement in the bale case to thereby compact the crop material into bales; a duct for transporting the crop material to the entrance opening; a stuffer unit operably associated with the duct and comprising: a fork assembly comprising tines; a drive mechanism acting on the fork assembly; and a clutch arrangement for selective coupling the drive mechanism to a power source of the agricultural baler, the clutch arrangement comprising: a selectively operable dog clutch comprising a driving clutch member and a driven clutch member that are arranged for rotation about a shared axis of rotation, wherein the driving clutch member and the driven clutch member are configured for selectively engaging each other in one direction of rotation of the driving clutch member relative to the driven clutch member; and an overrunning clutch associated with the driving clutch member and the driven clutch member, the overrunning clutch configured for engaging in an opposite direction of rotation of the driving clutch member relative to the driven clutch member. The agricultural baler according to claim 1 , further comprising a cam arrangement comprising a cam and a cam follower, wherein one of the cam and the cam follower is associated with the driven clutch member and another one of the cam and cam follower is arranged such that when the driven clutch member is rotated about its axis of rotation, the cam follower is in biased contact with and follows a cam surface of the cam over at least part of the angular positions of the driven clutch member about its axis of rotation, wherein the cam surface comprises a stop that is engaged by the cam follower when the driven clutch member is in an angular position about its axis of rotation that corresponds to a rest position thereof. The agricultural baler according to claim 2 , further comprising a resilient member that is at least partly compressed or stretched when the cam follower is in contact with the cam surface of the cam. The agricultural baler according to claim 1 , wherein the drive mechanism comprises at least one first crank that is rotatable about a first axis of rotation and that is associated with the driven clutch member. The agricultural baler according to claim 4 , wherein one of the cam and the cam follower is connected to or arranged on the first crank. The agricultural baler according to claim 5 , wherein: the fork assembly further comprises at least one fork lever having arranged thereon the tines; and the fork lever is acted upon by the first crank at a first pivot point on the one hand, and operably supported at a second pivot point on the other hand. The agricultural baler according to claim 6 , wherein the fork lever is operably supported at the second pivot point by a guide, allowing movement of the fork lever relative to the second pivot point along a predetermined path relative to the fork lever. The agricultural baler according to claim 7 , wherein: the second pivot point is fixed to a support member that is movable relative to the first axis of rotation of the first crank; and one of the cam and the cam follower is connected to or arranged on the first crank and another of the cam and the cam follower is connected to or arranged on the support member. The agricultural baler according to claim 7 , wherein the stuffer unit further comprises at least one second crank rotatable about a second axis of rotation, and wherein the second crank acts upon the fork lever at the second pivot point for moving the second pivot point relative to the second axis of rotation. The agricultural baler according to claim 7 , wherein: the guide comprises a journal coaxial with the second pivot point and cooperating with an oblong slot provided in the fork lever, the journal fits closely between the longitudinal sides of the slot, and upon rotation of the first crank, the second pivot point travels to and fro along a single line relative to and within the slot. The agricultural baler according to claim 9 , wherein the first crank acts upon the fork lever at the first pivot point via a cam track and an associated cam track follower. The agricultural baler according to claim 11 , wherein a position of the first pivot point is defined by the cam track, wherein the cam track is arranged on the fork lever and is engaged by a cam track follower that is acted upon by the first crank. The agricultural baler according to claim 11 , wherein a position of the first pivot point is defined by the cam track, the cam track acted upon by the first crank, the cam track engaged by a cam track follower on the fork lever. The agricultural baler according to claim 1 , wherein the overrunning clutch is one of a roller ramp overrunning clutch, a sprag overrunning clutch, and a wedge ramp overrunning clutch. The agricultural baler according to claim 1 , wherein the selectively operable dog clutch is a radial dog clutch. The agricultural baler according to claim 1 , wherein the selectively operable dog clutch is a single revolution clutch. |
