Abstract

A gate valve unit that can be used with existing animal feeders that have a feed container and aperture in the feed container for allowing the feed to be dispensed. Generally, the feed is gravity fed through the aperture and contacts a spinning feed dispensing member throwing the feed about the animal feeder. The invention includes a plunger-type gate that is solenoid actuated and is closed by one or more return springs. The spinning member and the plunger gate can be actuated together by either a timer or by a wireless command from a remote location.

Claims

1. A plunger gate attachment that can be added to an animal feeder, said animal feeder having a feed container with an aperture in the bottom of said feed container, wherein feed contained in said feed container tends to pour through said aperture and exit said feed container, said plunger gate comprising:

a housing, wherein said housing is attachable to said feed container at a location adjacent to said aperture;

a plunger, wherein said plunger is generally elongated and has a plunger end proximal to said housing attachment location and has a second end distal from said housing attachment location;

wherein said plunger is operatively connected with said housing such that said plunger moves in a generally perpendicular direction from said housing attachment location;

a top cap, said top cap having a solenoid in operative communication with said plunger and causing said plunger to move to either an open or closed position;

wherein said solenoid is in electrical communication with a power source;

wherein said plunger end is sized and shaped such that when said plunger is in said closed position said plunger end fills said aperture to the extent that said aperture is blocked from allowing feed to exit said feed container; and

wherein when said plunger is in said open position, said aperture is open allowing feed to exit said feed container.

2. The plunger gate attachment of claim 1 further comprising:

a return spring in operative opposition to said plunger moving to said open position;

wherein when said solenoid is activated by said power source, said plunger moves against said return spring opposition to said open position; and

wherein when said solenoid is deactivated, said return spring opposition causes said plunger to move into said closed position.

3. The plunger gate attachment of claim 2, wherein said housing is further comprised of:

a main housing containing said plunger;

a base, wherein said base is connectable to said feed container;

at least one support member having a first end connected to said main housing and a second end connected to said base; and

wherein said base has a base aperture.

4. The plunger gate attachment of claim 1, wherein said housing is attached to said feed container on the inside of said feed container.

5. The plunger gate attachment of claim 1, wherein said housing is attached to said feed container on the outside of said feed container.

6. The plunger gate attachment of claim 1, wherein said housing is attached to said feed container by one of:

fasteners, magnets, or adhesives.

7. The plunger gate attachment of claim 3, wherein said base is attached to said feed container on the inside of said feed container.

8. The plunger gate attachment of claim 3, wherein said base is attached to said feed container on the outside of said feed container.

9. The plunger gate attachment of claim 3, wherein said housing is attached to said feed container by one of:

fasteners, magnets, or adhesives.

10. A plunger gate attachment comprising, in combination:

a feed exit aperture in an animal feeder;

an attachable plunger gate located over said aperture;

said attachable plunger gate containing a plunger, said plunger being solenoid actuated;

wherein when plunger is unactuated, said plunger staying in a closed position that closes said aperture; and

wherein when plunger is actuated, said plunger staying in an open position that opens said aperture.

11. The plunger gate attachment of claim 10 further comprising a return spring attached to said plunger, wherein said return spring opposes said plunger moving to said open position.

12. The plunger gate attachment of claim 10 wherein said solenoid is adapted to be actuated by a timer.
