Abstract: A device and method which implements a preferred embodiment of the present invention includes a means for controlling the door of a shovel bucket. In one embodiment, an adjustable connecting rod may be configured to pivotally connect to a shovel bucket. A fixed connecting rod may be configured to pivotally connect to the adjustable connecting rod and pivotally connect to the door of the shovel bucket. The proximal end of the adjustable connecting rod may move in a direction towards the shovel bucket when the door is closing in order to lock the door. An eccentric assembly may be configured to move the proximal end of the adjustable connecting rod in a direction away from the shovel bucket after the door has closed in order to unlock the door.
