Anti-segregation steady flow bin

The invention relates to an anti-segregation steady flow bin. The anti-segregation steady flow bin comprises a bin body and a round-to-square elephant trunk fixed to the opening position in the bottom of the bin body, a vertically-arranged rectangular pyramid feeding hopper is further connected to the top of the bin body in an inserted mode, a first feeding pipe and a second feeding pipe which are obliquely arranged are further connected to the left side and the right side of the rectangular pyramid feeding hopper in an inserted mode correspondingly, and a square-to-round elephant trunk is further fixed to the opening position in the lower end of the rectangular pyramid feeding hopper and arranged inside the top of the bin body. According to the anti-segregation steady flow bin, three strands of materials which are larger in particle size difference and enter the bin body can be fully mixed in the rectangular pyramid feeding hopper in advance, then fall into the bin body by means of the square-to-round elepha
