摘要： The dog clutch for a square baler is normally retained in a disengaged position as a continuously driven sprocket rotates around it during baling operations. When a retainer for the dog is released, the dog is released by the retainer and flips out to an engaged position so as to be driven through one knotter revolution by a driving lug on the rotating sprocket, whereupon it is reset by the retainer into its disengaged position. An external lobe on the rotating sprocket blocks releasing movement of the retainer if the driving lug of the sprocket is in the immediate vicinity of the dog, which could otherwise cause an insecure engagement of the lug with the dog. The dog-engaging seat on the retainer is spring-loaded to provide yieldable relief in the event binding starts to occur between the retainer and the dog.
