DETAILED DESCRIPTION
Referring to FIG. 1, the present invention, an automatic animal feeder (10), comprises a barrel (20), spinner assembly (70), spinner plate (40), and control unit (60).
Barrel (20) is generally, a free-standing large container for storing the feed. Barrel (20) is surrounded by an upright circular base wall (25) with a bottom that forms funnel (27). Funnel (27) has a cone shape with opening (29) at the apex point. Funnel 27 conducts the feed through the opening (29) into spinner plate (40).
As shown in FIG. 2, spinner assembly 70 further comprises rod 75 centrally, perpendicularly and rigidly mounted upon the topside of base 80. As depicted in FIG. 7 elongated rod 75 extends vertically upward along the central axis to a predetermined distance into opening 29 of funnel 27. As shown in FIG. 2, bore 77 is disposed within base 80 extending vertically upward along the central axis of base 80 from the under side of base 80 to a predetermined distance within base 80.
Spinner plate (40) is circular in the preferred embodiment with surrounding upright walls (43) extending a short distance upward. As shown in FIG. 7, disposed within the center of spinner plate 40 is aperture 41 for receiving rod 75 therethrough as shown in FIG. 1.
As depicted in FIGS. 1 and 2, elongated shaft (45) is fixably mounted upon the top of control unit (60) and extends vertically upward through spinner plate (40) and into the bore 77 of base 80. On one side of base 80 is a set screw 82 which extends horizontally therefrom into bore 77. Set screw 82 is adapted to secure shaft 45 within bore 77 of base 80.
Referring to FIG. 3, there is shown an alternative embodiment for spinner assembly 70. In this embodiment bore 77, is adapted with internal threads. As depicted, shaft 45 is adapted with mating threads for engagement with the internal threads within bore 77.
As shown in the preferred embodiment of FIG. 1, the upright wall (43) of spinner plate (40) can flare outward in an arc, alternatively at an obtuse angle or alternatively at a right angle. Upright wall (43) extends a predetermined distance approximately below the height of the funnel (27). This configuration allows the rate and amount of flow of feed through the opening (29) of the funnel (27) as the spinner plate (40) rotates in conjunction with shaft (45).
As shown in FIG. 6, spinner plate 40 can be adapted with a plurality of spaced apart fins (85) circumferentially surrounding the peripheral edge (46) of spinner plate 40. Each fin (85) extends vertically upward to a predetermined distance below funnel (27).
Control unit (60) incorporates a conventional motor disposed below spinner plate (40). Control unit (60) can be adapted with a conventional timer for automatically setting the time for the elongated shaft (45) to rotate. In the preferred embodiment the conventional timer is set to rotate periodic throughout the day.
The rotation of the elongated rod 75 within the opening 29 prevents the stoppage of the feed from flowing through funnel 27. The rotation of rod 75 within funnel 27 causes vertical movement therein thereby preventing the stoppage of the funnel 27. This is the main advantage of this invention over the current automatic feeders in the market place today.
Control unit (60) can be adapted with a switch having control settings for controlling the movement of elongated shaft 45. The elongated shaft (45) can be adapted to rotate 360 degrees at a predetermined rate, can be adapted to pivot back/forth, can be adapted to move up/down or a combination thereof. The rate of movement of the elongated shaft (45) can be adjusted relative to the stirring rate of the feed within the funnel (27). In the preferred embodiment shaft (45) can be geared to rotate at different speeds through switch (64) of control unit (60).
As depicted in FIG. 5, the tip of the elongated rod (75) can be adapted with a plurality of spaced stirring spikes (87) or at least one. Each spike (87) is mounted to the external surface of elongated rod (75) not shown and protruded outwardly a short distance therefrom. Alternatively, the tip of the elongated rod (75) or the entire surface area of elongated rod (75) can be embedded with recesses forming a helical shape stirrer (90). With each rotation of elongated rod (75), helical shape stirrer (90) provides the capability of metering an exact amount of feed into spinner plate (40). In alternative embodiments both stirrer (90) and spikes (87) can be affixed to rod (75). The base (119) of rod (75) extends underneath rod (75).
As shown in FIG. 4, stirrer spikes 87 and/or helical shape stirrer spike 90 can be affixed to cover 100. In this embodiment, cover 100 comprises base 110 with a centrally located hollow shaft member 115 extending linearly upward therefrom. Hollow shaft member 115 is adapted to engage with elongated rod 75 shown in FIG. 2. In the preferred embodiment, hollow shaft member 115 is slidably engaged with elongated rod 75. In use, hollow shaft member 115 is engaged with elongated rod 75. Then, hollow shaft member 115 in conjunction with elongated rod 75 extends into the opening 29 of the funnel 27 as shown in FIG. 1.
