  • Patent number: 7712632
    Abstract: This invention is a material discharge apparatus for controlling the flow rate of flowable material being conveyed through a hopper, the apparatus includes a hopper with an inlet at the top to receive flowable material and a discharge outlet at the base of the hopper, a valve configured and arranged in the hopper, the valve has a lower end portion adjacent the discharge outlet forming a gap between the hopper and the valve for material discharge, with the valve fixedly connected to a fixed support beam, the hopper elastically connected to the same fixed support beam such that as the more material is received by the inlet, the more the hopper sags, the larger the gap formed between the valve and the hopper grows, thereby increasing the rate of flow of material discharge.
