Abstract
An automatic pet feeding system contains a first hopper adapted to contain food and an inner second hopper adapted to receive food from the first hopper. A movable screw operably communicates with the second hopper, and is configured to rotate at a predetermined time, and extrude food therethrough. The movable screw includes a periphery, an inlet, and an outlet. A screw housing contains the movable screw such that the movable screw is adapted to slidably engage an inner wall of the screw housing. A dish for receipt of the food is also included. Food is provided at a predetermined weight depending on the rotation of the movable screw.
Claims17
An automatic pet feeding system comprising:
- a first hopper adapted to contain food;
- an inner second hopper adapted to gravitationally receive and obliquely convey food from said first hopper;
- a movable screw adapted to rotate at a predetermined time, and extrude food received from said inner second hopper therethrough, said screw containing a periphery, an inlet, and an outlet;
- a screw housing containing said movable screw and an annular inner wall defining an inner diameter, whereby the periphery of said movable screw is adapted to slidably engage said annular inner wall of said screw housing completely across said inner diameter of said screw housing;
- and
- a dish for receipt of said food,
- whereby said food is provided at predetermined weights depending on the rotation of said movable screw.

- a movable screw adapted to rotate at a predetermined time, and extrude food obliquely conveyed from said inner second hopper therethrough, said screw containing a periphery, an inlet, and an outlet;
- a screw housing containing said movable screw and an annular inner wall defining an inner diameter, whereby the periphery of said movable screw is adapted to slidably engage said annular inner wall of said screw housing completely across said inner diameter of said screw housing;
- a process control board for transmission and receipt of signals, said process control board operably communicating with said movable screw to drive rotation of said screw;
- and
- a touch screen containing control buttons in operable communication with said process control board,
- whereby food portions and feed times as selectively determined on said touch screen;
- and
- a dish for receipt of said food,
- whereby said food is provided at predetermined weights depending on the rotation of said movable screw.

- a movable screw adapted to rotate at a predetermined time, and extrude food received from said inner second hopper therethrough, said screw containing a periphery, an inlet, and an outlet;
- a screw housing containing said movable screw whereby said movable screw is adapted to slidably engage an inner wall of said screw housing;
- a dish for receipt of said food;
- a process control board for transmission and receipt of signals;
- a dosage regulator for predetermining the weight of disbursed food;
- and
- a variable resistor weight control in operable communication with said dosage regulator,
- whereby adjustment of said dosage regulator drives the variable resistor weight control to send a signal to the process control board, and
- whereby said food is provided at predetermined weights depending on the rotation of said movable screw.
