The invention discloses a feeding device with a bird-repelling and rat-preventing function. The feeding device comprises a box body, a first motor is fixedly connected to the left side surface of theinner wall of the box body, a threaded rod is fixedly connected to an output shaft of the first motor, a threaded nut is in threaded connection with the surface of the threaded rod and is clamped on the left side surface of a sliding block, and the bottom of the sliding block is slidingly connected to the interior of a sliding groove formed in the lower surface of the inner wall of the box body. According to the feeding device with the bird-repelling and rat-preventing function, through the arrangement of the first motor and a second motor, when the first motor works, a feeding box can be pushed out of or retracted into the box body, after poultry are fed, remaining feed is preserved and cannot be eaten by rats, when the second motor works, a bird-repelling device can be driven to rotate,and after the bird-repelling device rotates, birds can be repelled and prevented from flying down from air to steal the feed; thus, the feed can be preserved, the waste of the feed cannot be caused, and convenience is brought to the people during poultry breeding.
