A dipper assembly includes a dipper, a dipper door, a closure mechanism, and one or more block assemblies. The dipper door is pivotally mounted to the dipper, and has a closed position in which the dipper door covers the dipper bottom. The closure mechanism has a locked position and an unlocked position, and is coupled to the dipper back and the dipper door. In the locked position, the closure mechanism holds the dipper door in the closed position. In the unlocked position, the closure mechanism allows the dipper door to swing away from the closed position. The block assemblies are coupled to the dipper back and limit a rotation of the side link plate to a pre-defined angle that corresponds to the closed position.

Dipper door assembly

A dipper assembly includes a dipper, a dipper door, a closure mechanism, a trip assembly, and a camshaft support assembly. The dipper door is pivotally mounted to the dipper for movement between an open position and a closed position in which the dipper door covers the dipper bottom. The closure mechanism is configured to retain the dipper door in the closed position. The trip assembly is configured to release the dipper door for movement to the open position, and includes a trip arm coupled to a camshaft and also coupled to a trip rope. The camshaft support assembly is configured to receive the camshaft, and includes a bearing block receiving a rotatable bearing member, and a sealing mechanism.

A dipper assembly includes a dipper, a dipper door, and a closure mechanism. The dipper door is coupled to the dipper, and has a closed position in which the dipper door covers the dipper bottom. The closure mechanism has a first position and a second position. In the first position the closure mechanism is configured to permit movement of the dipper door away from the dipper bottom. In the second position, the closure mechanism is configured to retain the dipper door in the closed position. The closure mechanism includes a link having a first leg and a second leg, one or more side link plates coupled to the link and to the dipper back, and a closure mechanism pin assembly configured to adjust the position of the link relative to the dipper door.
