Description

SPECIFICATION Animal feeding apparatus This invention relates to improvements in animal feeding apparatus and is more particularly directed to an animal actuated apparatus in which the flow of the feed and water, as desired by an animal, is completely under the control of the animal whereby the nutritional and life sustaining elements of food and water may be obtained according to the needs of an individual animal.

The prior art is replete with examples of various and sundry apparatus and devices for feeding and watering animals which supply varying amounts of particulate feed material as well as liquids, such as water, to a bunk or trough, for consumption by the animals.

The following is a list of prior art noted as pertinent to the invention of this disclosure: Patent No. Inventor Issue Date 1,334,075 Borton 16/3/20 1,362,974 Wagner 21/12/20 1,396,257 Corington 8/11/21 1,553,502 Boyes 15/9/25 2,234,112 Emrick 4/3/41 2,513,200 Pax 27/6/50 3,067,722 Strong 11/12/62 3,144,003 Jacobs 11/8/64 3,536,046 Lippi 27/10/70 3,812,823 Ridderetal 28/5/74 4,242,985 Freeborn 6/1/81 Of the patent numbers noted above, the Wagner patent 1,362,974 for Automatic Stock Feeder is illustrative of one of the many devices for delivering feed to an animal and the Lippi patent number 3,536,046 for Combination Feeder and Waterer for Hogs illustrates a combined water and feed device. The Freeborn patent number 4,242,985 for Animal Actuated Feeder illustrates still another recent feeder of substantial complexity.

Controlled trials by scientific institutions have demonstrated an advantage in the feeding of mixtures of dry meal food with water in the improvement of feed conversion figures, i.e. fewer units of feed meal are required to achieve one unit of liveweight gain.

It is an object of this invention to provide an improved livestock feeding and watering apparatus that is reliable and uncomplicated in operation while permitting the stock to select portions and proportions of this solid and liquid dietary components in a manner determined by their needs and desire.

On one hand, my apparatus provides an animal controiled liquids dispensing feature that is operative to prevent the accumulation of excessive amounts of liquids in relation to the amount of feed that may be dispensed into the feeding bunk, or trough. The apparatus of this invention further provides a simple, positive, dispensing-agitating function which ensures that feed from a hopper is delivered under the control of the animal when needed or desired. As will be explained in more detail below, my invention further includes a means for agitating the feed contained in a hopper to prevent bridging or the like that may interfere with the continuous dispensing of the feed from the bottom of the supply hopper.

With these and other objects of this invention in mind, it may be seen that feed and water dispensing mechanisms are disposed over a trough, or bunk, whereby a hopper is provided with a longitudinally extending slot adjacent one bottom side and a plurality of feed dispensing elements containing portions that are operable through the slot between positions on either side of the slot and which may also include upwardly extending feed agitating means in the form of grates extending upwardly from and driven by the dispensing elements.Liquids dispensing means depend downwardly from the bottom of the hopper to actuators, therefor, that are disposed, with relationship to the bunk, to provide liquid dispensing operation, by an animal's snout, for example, in such a manner that the level of liquid that may be dispensed into the bunk is limited, through the animal's behaviour, to a predetermined level.

Fig. 1 is a side elevational view of an animal actuated feed and water dispensing apparatus; Fig. 2 is a top plan view of the apparatus shown in Fig. 1; Fig. 3 is a sectional view of the apparatus shown in Fig, 1 taken along section line 3-3; Fig. 4 is a sectional view of a portion of Fig. 3 taken along section line 4-4; and Fig. 5 is an enlarged sectional view of a portion of Fig. 1 taken along section line 5-5.

Referring to the drawings a feeding and watering apparatus is indicated generally by reference character 10 and is comprised of a bunk or trough 11, disposed underneath a hopper indicated generally by reference character 20.

Bunk 11 may be of generally rectangular shape and is adapted to receive a volume of water and/or feed in amounts determined by the stock to be fed and includes a bottom portion 1 3 and a top portion 12 having suitable means, shown in the form of a peripherally disposed metallic angle 30, while the bunk itself may be comprised of suitable material, such as concrete or plastic.

Hopper 20 includes a front sloping wall 21 having a top 22 and a bottom 23; a sloping rear wall 25 that is provided with a bottom portion 26 of lesser slope, with respect to the horizontal plane of bunk 11 and which terminates in a forwardly extending edge 27, that is disposed underneath and adjacent the lower portion 23 in front wall 21 to define an elongated slot 24, and a pair of end walls 28 and 29 suitably shaped to extend downwardly into mounting engagement with a frame 30 on the top portion 12 of bunk 11 and are joined to front and rear walls 21 and 25 by suitable connectors, welding or the like. A plurality of leg members 33 are angularly disposed intermediate frame 30 on bunk 11 and suitable locations on front and rear walls 21 and 25 on hopper 20 so as to properly support the hopper in operative dispensing position above bunk 11.

A further vertical support plate 32 is shown disposed extending upwardly from a horizontally disposed angled support member 31 on frame 30, and is suitably connected to bottom portion 26 on rear wall 25.

A cruciform shaped dispenser-agitator bar 35 is shown rotatably disposed on a bolt 37 extending upwardly through bottom portion 26 of rear wall 25 and includes sidewardly extending wing portions 38 forming the principal cross-member, a forwardly extending tongue portion 39 for engagement with an actuator, and an upstanding pin member 40 extending toward the interior of hopper 20. The forward end of tongue 39 may be suitably shaped for engagement by an actuator and it may be noted that the wings 38 are disposed for movement into and out of slot 24 in front wail 21 as bar 35 is caused to rotate about bolt 37. The relative thickness of dispenseragitator bar 35 may be determined, at least in part, by the relative size of the particulate feed material that is customarily supplied in the form of a dried granular food product.A plurality of hopper agitator grates 43 are shown disposed for rotation about bolt 45, extending through the top of front wall 21, at their top ends and are provided with an appropriate disposed aperture 46 at their lower ends, for operative engagement with pin 40 on dispenser-agitator bar 35 for actuation thereby.

Hopper agitator grates 43 are shown as having a plurality of vertically extending bar members 47 and the entire grate may be seen to be operative in a plane substantially adjacent to and parallel with front wall 21 on hopper 20.

A feed regulator 49 is shown adjustably slidably disposed adjacent to slot 24 in front wall 21 and includes a generally horizontally disposed longitudinally elongated gate, or bar 50, that is mounted on the lower end of an upwardly extending rod 51 that is provided with an adjustment means 52 (shown in the form of a threaded socket) that coacts with a bolt 53 extending through a flange at the top edge of front wall 21.

An actuator arm 55, for dispenser-agitator bar 35, is shown having a bifurcated top end 56 in operative engagement with tongue 39 and is rotatably disposed on a bolt 57 extending through vertical support plate 32 and includes a downwardly depending portion 58 emanating in a generally horizontally extending finger member 59 that is adapted to be engaged by an animal. It may be appreciated that actuator arm 55 provides a side to side motion that is limited in angular extent by the provision of stop members 34 disposed on centre frame member 31.

A liquids manifold 62 is shown extending from the top and horizontally underneath hopper for connection to a plurality of valves 65, in cylindrical support tubes 63 mounted upon and carried by centre frame 31. Valves 65 having downwardly extending actuators 67, are removably disposed in the lower end of valve support tube 63 through one or more retaining bolts 66 and are shown connected to manifold 62 through hoses 64.

Valve 65 and the lower end of support tube 63 are disposed a suitable vertical distance above the bottom 13 of bunk 11 to tend to inhibit the stock from actuating the valve after the level of liquid in bunk 11 has reached a predetermined desired depth.

A front cover plate 32A may be disposed to extend horizontally in opposed relationship with vertical support plate 32 to form a channel therebetween so that feed existing from slot 24 in hopper 20 may fall downwardly therebetween and into the centre of bunk 11.

With the above description in mind, it may be seen that my invention provides a multi-station animal feeding apparatus that may be used on the front and rear sides by a plurality of animals wherein a liquids dispensing means is disposed between adjacent feed stations and each of the feed stations is provided with a solids feed dispenser and both the liquids and solids dispensers may be operated by, for example, the snout of an animal from either the front or rear sides of the food receiving bunk, or trough. The liquids dispensing means provides an adjustable control over the normal level of fluid to be maintained, by the animals, in bunk 11 and may be reached from all sides and the feed dispensing means, including actuator arm 55 and finger 59 may be actuated from either the front or rear sides of bunk 11.

With the apparatus assembled as indicated in Figs. 1 and 2, manifold 62 is connected to a suitable source of liquids under pressure and hopper 20 is filled with dry particulate feed material, appropriate for the type of livestock to be fed. Through instinct, hunger and thirst, the livestock may approach bunk 11 and engage valve finger 67 or actuator arm finger 59 to cause a flow of liquids and/or solids into bunk 11.The level of the liquids will be determined, to a large extent, by the dispositions of the lower end of valve tube 63 above the bottom surface 1 3 on bunk 11 whereby when the liquid rises to a level at which the nostrils of the snout of an animal become immersed, the animal will be inhibited from actuating valve finger 65 and the animal may then merely drink or may then direct its attention to finger 59 on actuator arm 55, again with its snout, causing dry feed to be dispensed from slot 24 into bunk 11. The dispensing of the feed from hopper 20 is effected by the to and fro sidewise motion of actuator arm 55 which causes a rotation of dispenser-agitator bar 35 about bolt 37 to cause wings 28 to alternately oscillate into and out of slot 24. The oscillatory, rotation motion of cruciform shaped dispenser-agitator bar 35 also causes a rotating oscillating motion of agitator grates 43 about bolts 45 to loosen material adjacent front wall 21 on hopper 20 and allow it to flow freely into proximity of dispenser-agitator bar 35. The opening defined by slot 24 at the bottom of front wall 21 on hopper 20 is adjustable and may be sized to coact with the thickness of dispenser-agitator bar 35 in relationship to the granular size of the particulate feed material.

When suitably dimensioned and sized, the oscillating action of dispenser-agitator bar 35 through slot 24 effects a positive displacement, "pumping" action of the material sliding down the inside of front wall 21 into proximity of the inner portion of slot 24.

Thus, according to the needs and desires of the livestock, the individual animals may either drink or feed, or both, and may act according to their learning capacities to satiate their appetites in a manner that is pleasing to their tastes.

The invention is not confined to the embodiment described with reference to the drawings. For example the bunk or trough may be integral with the rest of the apparatus. The apparatus may advantageously be constructed either wholly or in part from corrosion resistant materials such as aluminium stainless steel, glass fibre, rubber or plastics materials.

A plurality of apparatus according to the invention may be supplied by means of a mechanised feed distribution system adapted to deliver feed to each hopper.
