Abstract
A hopper for an automatic weighing apparatus has a link mechanism for opening and closing a hopper gate and an attachment mechanism for attaching a hopper body to the automatic weighing apparatus. The link mechanism includes a drive link pivotably mounted on a bracket, a follower link angularly movable in unison with the gate, and an intermediate link interconnected between the movable ends of the drive and follower links. When the gate is closed, the drive and intermediate links are aligned along a substantially straight line to prevent the weight of articles in the hopper from opening the gate. The attachment mechanism includes a pair of brackets attached to and projecting from the hopper, two parallel shafts mounted on and between the brackets, at different distances from the hopper body, and an attachment member mounted on the automatic weighing apparatus and having upwardly opening recesses for receiving the shaft closest to the hopper body and downwardly opening recesses for receiving the shaft farthest from the hopper body.
