Feeding device and discharging system

The invention discloses a feeding device and a discharging system. The feeding device comprises a first hopper (10), a chute (21) communicated with a discharge port of the first hopper (10) and formed obliquely, and a wedge disc (40) installed at an outlet of the chute (21) in a vertical moving mode so as to close and open the chute (21). According to the feeding device, due to the fact that the wedge disc is arranged in the vertical direction, when materials fall down from the first hopper, the acting force, acting on the wedge disc, of the materials is greatly reduced compared with the prior art, friction force needing to be overcome when the wedge disc moves is also greatly reduced accordingly, deformation of the wedge disc is avoided, and working efficiency is prevented from being affected by deformation of the wedge disc.
