The invention relates to a vibrating feeding box, comprising a material box, a buffer board, a screen mesh, an impurity-removing door and a discharging pipe, wherein the buffer board is obliquely placed in the middle of the material box and located below a discharge outlet of an ore pipe pipeline; the screen mesh is horizontally placed in the middle of the material box and connected with the buffer board; the impurity-removing door is arranged on the sidewall, located at the side away from the buffer board, of the screen mesh; the discharging pipe is located below the impurity-removing door, and communicated with the inner bottom of the material box; a vibrator is mounted on the inner lower end of the material box at a position corresponding to the lower end of the screen mesh; and the vibrator is connected with the screen mesh and is connected with a power supply through a time relay. Compared with the prior art, the invention has the advantage that since the time relay is turned on at a fixed time to periodically transmit the electric energy of the power supply to the vibrator and the vibrator drives the screen mesh to vibrate, the feeding efficiency is enhanced.
