Benefits of technology

This patent describes a snubber for a dipper door and a linkage assembly for controlling the movement of a door relative to a body. The snubber is a mechanism that provides resistance to the door when it is closing, and the linkage assembly is designed to pivotally connect the door to the body and control the movement of the door. The technical effects of these inventions include reducing the likelihood of damage to the door, improving the stability of the door in its open and closed positions, and enhancing the overall performance of the door assembly.

Problems solved by technology

If the door is allowed to swing freely it can slam into the body which has a deleterious effect on the working life of the dipper.

Abstract

A linkage assembly is provided for a bucket in which a door is coupled to a body of the bucket at a pivot mount. The linkage assembly includes a first link, a second link, and a snubber. The first link is pivotally coupled to the body and disposed in a spaced-apart relation to the pivot mount. The second link is pivotally coupled to the door and disposed in a spaced-apart relation to the pivot mount. The first and second links are also pivotally coupled together at a link pivot. The snubber is disposed between the pivot mount and the first link.

Description

TECHNICAL FIELD[0001]The present disclosure generally relates to a snubber for a dipper door. More particularly, the present disclosure relates to a snubber for a dipper having a body and a movable door coupled to the body.BACKGROUND[0002]Many industrial machines such as rope shovels, diggers, excavators, and the like employ dippers to dig, haul, and transport materials in a given job site. Each of these machines may employ a specific configuration or type of dipper to meet the particular requirements of an application. In the case of a rope shovel, the dipper may typically be configured to have a body and a door that is pivotally coupled to the body so as to allow a swinging movement of the door in relation to the body. If the door is allowed to swing freely it can slam into the body which has a deleterious effect on the working life of the dipper.[0003]Numerous designs and mechanisms of linkages have been developed by various manufacturers of such industrial machines to allow the ...
