Broadcast feeder
View Patent ↗A feeder assembly for dispensing feed to wildlife and other animals. The assembly includes a hopper, such as a conventional gravity-feed hopper. The assembly includes a broadcast feeder that sprays feed from a spinning tray driven by a motor. The feeder housing includes domed plates above and below the tray to direct the spray of feed peripherally and prevent varmints from operating the tray manually. The feeder housing may include an attachment plate to attach the feeder to the inside or outside of the bottom of the hopper. The housing may include a collar that is threadedly connectable to a downwardly extending neck on the attachment plate so the housing can be easily connected to and disconnected from the hopper. A chute control plank in the neck of the housing opens and closes the chute to allow removal of the feeder from the hopper without spilling feed.
1 . A broadcast feeder for dispensing granules of feed from a feed hopper, the feed hopper having a bottom with a bottom surface defining a central opening therethrough, the feeder comprising:
a housing comprising:
an attachment plate having a feed opening and attachable to the bottom of the feed hopper;
a chute depending from the attachment plate and configured to receive feed from the feed hopper through the central opening in the bottom of the feed hopper;
a dispenser rotatably supported in the housing and positioned to receive feed from the chute and to throw feed radially by centrifugal force when the dispenser rotates;
wherein the housing further comprises an upper guide plate above the dispenser and a lower guide plate below the dispenser, wherein each of the upper and lower guide plates defines an outer circumferential edge, wherein each of the upper and lower guide plates extends a distance beyond the dispenser, wherein each of the upper and lower guide plates is domed forming a surface that slopes downwardly toward the outer circumferential edge, and wherein the outer circumferential edges of the upper and lower guide plates are spaced from each other a distance selected to prevent selected varmints from reaching the dispenser; and
a motor supported in the housing and operatively connected to the dispenser to rotate the dispenser.
2 . The broadcast feeder of claim 1 wherein the lower guide plate is imperforate to the feed granules.
3 . The broadcast feeder of claim 1 wherein the slope of the upper guide plate is greater than the slope of the lower guide plate.
4 . A feeder assembly comprising the broadcast feeder of claim 1 and a feed hopper.
5 . The broadcast feeder of claim 1 wherein the chute is cylindrical.
6 . The broadcast feeder of claim 1 wherein the upper guide plate has an uppermost surface and wherein the uppermost surface of the upper guide plate is spaced a distance below the bottom surface of the feed hopper.
7 . The broadcast feeder of claim 3 wherein the dispenser has a bottom and wherein the circumferential edge of the upper guide plate is below the bottom of the dispenser.
8 . The broadcast feeder of claim 7 wherein the dispenser comprises a tray.
9 . The broadcast feeder of claim 1 wherein the attachment plate has a bottom surface, wherein the chute has an upper end and a lower end, and wherein the upper end of the chute is attached to the bottom surface of the attachment plate.
10 . The broadcast feeder of claim 9 wherein the upper guide plate has an upper surface attached to the lower end of the chute.
