Agricultural baler with hay dogs - has dogs pivotally mounted on opposite sides of bale case wall and biassed by spring to normal position

摘要

The hay dogs for an agricultural baler penetrate deeper into the bale case than is usual so as to prevent the compressed crop from expanding back into the bale case when the baling plunger retracts. Each hay dog comprises a fixed dog portion (37) of reduced height, combined with a movable dog portion (38) which, in its normal position penetrates the bale case beyond the fixed hay dog portion. Each movable portion may comprise a pair of arms (44, 45) pivotally mounted at (46) and urged against a stop (43) by a spring (51). A needle passes a binding medium around the bale may pass through the opening (50).
