A FEEDING DEVICE

Abstract: A feeding device (1) for feeding hogs and pigs. The feeding device (1) consists of a tube (2) mounted on a frame (7) which is fixedly mounted on a base (3). The tube (2) is suspended in at least two members (5, 6); in a suspension member (5) and a guiding member (6). The tube (2) is suspended freely rotatably in the suspension member (5). The guiding member (6) may be displaced in vertical direction on the frame (7) and is provided on its inner side with an elastic, flexible, annular body (10). The elastic, flexible, annular body (10) of the guiding member (6) will actuate the tube (2) so that after a swing it will return to its neutral, vertical original position. This feature combined with the vertical displacement of the guiding member (6) makes the feeding device easily adaptable to animals of different sizes.

Description: A FEEDING DEVICE Background of the invention The present invention relates to a feeding device for feeding animals, especially hogs and pigs, said feeding device comprising a base designed with a trough over which, on a frame fastened to the base, a tube is suspended, said tube constituting at its upper end a container for storing feed and at its lower end a dispenser unit for dispensing the feed, said tube being suspended and guided in at least two members, an upper suspension member and a lower guiding member, the lower guiding member being mounted on the lower part of the frame and being movable in vertical direction whereas the upper suspension member is fixedly mounted on the upper part of the frame. A feeding device for feeding hogs and pigs is known from WO-93/13652. The feeding device comprises a base on which a trough is formed. Mounted on this base is a frame partitioning the trough. On this frame and directly over the centre of the trough a tube is mounted. This tube serves as a feed dispenser at its bottom and as a feed container at its top. The function of the feeding device is such that the animal, when hungry, presses its snout against the dispenser part in order to displace it. This is possible since the dispensing part is made from an elastic flexible material. The deflection of the tube will result in a larger opening between the trough and the opening of the tube, and feed will be dispensed onto the trough. However, a feeding device of the above-mentioned type involves disadvantages. Among other things, it has turned out to be difficult to provide an elastic flexible tube for a young pig. Firstly, it is hard to modify the physical properties of the feeding device so as to adapt it optimally to the forces which the animals exert on the tube, i.e. the sizes of the animals. Secondly, the tube will be costly in production since an elastic flexible material is relatively expensive. Thirdly, it is not possible in a simple manner to adjust the amount of feed to be dispensed from the tube. It is the object of the present invention to provide a feeding device which is simple and inexpensive in production, a feeding device wherein it is easy to adjust the dispensed amount of feed, and a feeding device which is adaptable so as to suit the sizes of the animals. This object is achieved by a feeding device of the kind mentioned in the introduction which is characterized in that the tube is suspended freely rotatably on the frame in the upper suspension member, that the tube is essentially stiff, and that the lower guiding member comprises an elastic, flexible, preferably annular, member so that the lower end of the tube may be displaced in relation to the trough. The feeding device according to the present invention is an improved and alternative solution to the problems underlying the above-mentioned feeding device according to WO-93/13652 and all measures and indications therein will also apply to the feeding device according to the present invention and are hereby incorporated by reference into the present application. With a feeding device of this type it is possible to produce a feeding device - wherein the tube may be produced from an inexpensive stiff material, - wherin the adjustment of the desired amount of feed being dispensed is uncomplicated simply by displacing the tube vertically, and - wherein the adaptation to the sizes of the animals is accomplished in an uncomplicated manner simply by exchanging the elastic flexible annular body. The above-mentioned features are obtained by suspending the stiff tube, at its upper end, in an annular suspension member, freely rotatably on the frame, and by guiding it underneath said suspension member in the lower flexible elastic guiding member. The desired swing of the tube and the resulting dispensing of feed is obtained in that the inner side of the annular body which contacts the tube comprises an annular flexible elastic material. After a swing and dispensing of feed this causes the tube to become actuated so that it resumes its neutral vertical original position. The vertical position of the guiding ring on the frame may be varied, and the inside diameter of the guiding ring may be varied, and the elasticity of the elastic flexible material may be varied. This makes it possible for a standard feeding device according to the present invention to be adapted to animals of virtually all sizes. Thus, the feeding device may also be adapted for use by other animals than pigs. Description of the drawing The present invention will be explained in further detail below with reference to the accompanying drawing showing a feeding device according to the present invention. The drawing shows a feeding device 1 according to the present invention. The feeding device comprises a tube 2 located immediately above a base 3 which is formed with a trough 4. The tube 2 is mounted on a frame 7 by means of two annular members 5 and 6. The upper member is a suspension member 5 mounted freely rotatably on the frame 7. The lower one is a guiding member 6 mounted on me frame 7. The guiding member 6 may be displaced in vertical direction on the frame 7. The member 8 is an assembly member between the two halves of the frame 7. This member may be omitted if the frame 7 is stiff in itself. The guiding member 6 of the illustrated embodiment consists of a stiff annular circular holder 17 in which an elastic flexible annular body 10 is mounted. By means of a handle 11 the suspension member 5 may be displaced in vertical direction in relation to the frame 7 so as to place the tube in the desired position, i.e. from totally closed (contacting the trough) to its maximal height above the trough 4. A feeding device of this type is connected at the top of the tube 2 to a pipe 12 for automatic filling of feed and a water pipe 13. The water pipe 13 is connected to a hose 14 fixed to the frame 7. The hose 14 is bifurcated further down the frame 7. Either of these two branches lead into a hollow 15 formed in the base 3. The hollows 15 are provided on either side of the trough 4. At its end the hose 14 is equipped with a nozzle 16 which, when actuated, e.g. by a snout, allows the passage of water. Inside at its bottom the holder 17 according to a particularly preferred embodiment is provided with an annular recess extending toward the centre of the holder 17. This is advantageous since it is then not necessary to fasten the elastic flexible annular body 10 to the holder 17, e.g. by means of glue. The elastic flexible annular body 10 will thus be easily replaceable if it is desired to use a different body 10 with modified flexibility. This makes it possible easily to adapt the feeding device to animals of different sizes. It is easy to form the body 10 from a rod-shaped flexible body which is folded and placed in the recess of the holder 17. The holder 17 may further be provided with a bead at its upper edge in order to ensure that the body 10 does not unintendedly slide out of the holder. This easy access to exchange of the elastic flexible annular body 10 of the guiding member 6 is what ensures that the feeding device may quickly be adapted to different sizes of animals. Alternatively, the guiding member 6 is made of a ring provided with elastic flexible straps which are fastened to the frame 7. A guiding member of this type will normally be provided with 2, 4 or 6 straps.
