An energy-saving particle distributing device comprises a rotating shaft, a rotating plate, a funnel, an upper partition plate, a lower partition plate, movable baffles, fixed baffles, gears, an upper outlet, a lower outlet and a shell. The energy-saving particle distributing device is characterized in that the funnel is of a symmetrical structure, the rotating shaft is located on the symmetrical sections of the funnel, the rotating plate can adjust the rotation angle under the drive of the rotating shaft, and after entering the shell from the funnel, particles fall to the inclined upper partition plate and the inclined lower partition plate correspondingly from the two sides of the rotating plate due to partition of the rotating plate; and the movable baffles are provided with racks, and the movable baffles can be driven by the gears to move up and down along hollow structures of the fixed baffles so that the sizes of the gaps between the movable baffles and the partition plates can be changed. According to the energy-saving particle distributing device, the fallen particles are distributed to the two partition plates through the rotating plate arranged below the funnel, distribution of the particles to the two partition plates can be adjusted through the control over the angle of the rotating plate and the sizes of the gaps between the movable baffles and the partition plates, reciprocating swinging is not needed, the energy consumption is small, and the structure is simple.
