Feeding device with automatic proportioning function for livestock raising

The invention relates to a livestock feeding device with an automatic matching function. The livestock feeding device comprises a feed trough. Feed grids are placed in the feed trough, and a feed mixing disc is arranged on the feed trough. A plurality of feeding bins are arranged on the mixing disc; an opening and closing mechanism is arranged in each feeding bin; a rotary mixing mechanism is arranged in the mixing disc; the rotary mixing mechanism is provided with a receiving bin corresponding to each feeding bin; a weighing assembly is arranged in the material receiving bin; the receiving bin is connected with the rotary mixing mechanism through a turnover mechanism; and a discharge hole is formed in the bottom of the mixing disc. The rotary mixing mechanism is started, and the turnover mechanism is started in the rotating process of the rotary mixing mechanism, so that the receiving bin is turned over, and raw materials in the receiving bin can naturally fall into the mixing cavity, namely, on the surface
