Precise feeding device for caged animals and control method

The invention discloses an accurate feeding device for caged animals and a control method. The feeding device comprises an auger conveying assembly arranged at the bottom of a hopper, a constant-speed walking feedback assembly used for feeding back the traveling condition of a feeding machine and a channel variable feedback assembly used for feeding back the discharging condition of channel feed. According to the control method, a constant-speed cruise control unit, a precise feeding control unit and a single-chip microcomputer are adopted. The auger conveying assembly actively pushes the feed, the problem that the feed is arched and blocked in a feed pipe is solved, and discharging obstacles are avoided; the single-chip microcomputer regulates and controls the running speed and the feeding amount of the feeding machine according to fed-back constant-speed walking feedback information and channel variable feedback information, constant-speed cruising and accurate feeding are achieved, and good practical and p
