The invention discloses a fishpond feeding device and relates to the technical field of aquaculture. The fishpond feeding device comprises a floating ball, supporting frames are symmetrically installed on one side of the floating ball, buoyancy plates are fixedly connected to the ends, away from the floating ball, of the supporting frames, charging openings are symmetrically formed in one side of the floating ball, discharging openings are formed in the sides, away from the floating ball, of the charging openings, a partition plate is fixedly connected to the inner wall of the floating ball and is a hollow plate, a first magnet block is slidably connected into the partition plate, connecting ropes are symmetrically installed on one side of the partition plate, scraping devices are symmetrically installed on one side of the partition plate, quantity control devices are fixedly connected to the ends, away from the partition plate, of the connecting ropes, and discharging devices are symmetrically installed at the positions, close to the charging openings, of the inner wall of the floating ball. According to the fishpond feeding device, the purpose of scraping feed accumulated on the surface of the partition plate is achieved, and the problem that the feed is accumulated in the device and cannot be scattered is effectively solved.
