The apparatus comprises a hydraulic unit mounted directly on the wall of the bottom of a rotary hopper and supplying hydraulic fluid to each of the jacks mounted on the hopper wall. This hydraulic unit is connected to an energy source on a fixed bracket located in the region of the bottom of the hopper, but which is independent therefrom. As the rotary hopper rotates, the hydraulic unit retains its connection with the energy source. The energy source activates the hydraulic unit, which subsequently opens the hopper. |
