Abstract
An animal feeding device, especially for pigs, has an overhead feed metering or regulation mechanism formed of a cylindrical member resting in a slot across the bottom of a feed hopper to close the slot and prevent feed from falling from the hopper. The bottom of the member is accessible from below the slot and the pig causes feed to fall from the slot by pushing the member up with its nose to open the slot. When the member is released by the pig, it falls back down into the slot to close same. The member can be a tube or pipe retained in operable open and closed position by a rod extending therethrough.
Claims6
An animal feeding device for automatically supplying feed to the animal as the animal desires, comprising:
- A. a vertically extending rear wall and a pair of opposed side walls joined to said rear wall and together forming a frontwardly opening chamber;
- B. a bottom wall extending between said rear and side walls at the lower margins thereof and forming a feed trough therewith adapted to receive and retain feed therein from which the animal can eat;
- C. a hopper wall extending between said opposed side walls and adjacent said rear wall at the top of said chamber to form a feed hopper adapted to receive and retain therein feed to be supplied to said feed through, said hopper wall and rear wall forming a slot therebetween extending from side wall to side wall, said slot adapted to be above the shoulders of said animal and having a uniform width along its length;
- and,
- D. regulation means located in said slot selectively to open and close said slot in response to operation by said animal at a location above its shoulders to regulate the flow of feed falling from said hopper to said trough under action of gravity, said regulation means including a cylindrical member having a length substantially the length of said slot and a diameter greater than said slot width with the cylindrical member arranged in said hopper and resting in said slot to close same and prevent feed from falling through said slot from said hopper, said cylindrical member being adapted to be raised from below said hopper by the nose of the animal to open said slot and allow feed to fall from said hopper, said cylindrical member is hollow through the length thereof and said regulation means further include a rod extending from side wall to side wall above said slot with the cylindrical member arranged with the rod extending through the hollow thereof to limit the movement of said rod upwardly from said slot.
An animal feeding device for automatically supplying feed to the animal as the animal desires comprising a generally vertically-extending rear wall and a pair of opposed side walls joined to said rear wall, a hopper wall extending between said opposed side walls and cooperating therewith to form a feed hopper, said hopper wall and said rear wall forming a slot of substantially uniform width along its length, and regulating means in and above said slot and vertically movable to open and close said slot in response to operation by said animal, said regulating means including hollow cylindrical means having a length substantially equal to the length of said slot and a diameter greater than said slot width, said hollow cylindrical means arranged in said hopper and resting in said slot to close said slot and prevent feed from falling through said slot, and support means extending from said opposed side walls into said hollow cylindrical member to limit the upward movement of said hollow cylindrical means in response to movement by said animal.
