DESCRIPTION:
BRIEF SUMMARY
The invention provides a mash-feed trough as stated in claim 1.
If the feature of claim 2 is applied, a solid trough will be obtained which is easy to clean and which will not be destroyed by the animals biting it. Known plastic troughs are destroyed by being bitten, starting at the corners. Metal troughs are expensive since they have to be manufactured from stainless steel. The trough according to the invention can be manufactured at a low cost price, is easily cleaned and yet is not destroyed by being bitten. This trough has no corners in which feed which has not been consumed can deposit and decay. The mash-feed trough according to the invention preferably contains closing and delivery means, this as indicated in one or more of the claims.
The invention will now be elucidated in the description following hereinafter with reference to a drawing. In the drawing:
FIG. 1 shows a perspective, broken away view of a preferred embodiment of a mash-feed trough according to the invention;
FIG. 2 shows on a larger scale a perspective, broken away view of detail II from FIG. 1;
FIG. 3 shows on a larger scale a top view, partially in section, of the mash-feed trough from FIG. 1;
FIG. 4 shows on a larger scale a section along line IV--IV from FIG. 1;
FIG. 5 shows a perspective view of a fraction of another mash-feed trough according to the invention corresponding to FIG. 4; and
FIG. 6 shows a vertical section through a fraction of yet another mash-feed trough according to the invention.
Mash-feed trough 1 from FIGS. 1-4 comprises a casing 2 of which the external bounding consists of a corner-free plastic envelope 3. This is preferably a piece of round PVC piping like that for example available on the market as drain-pipe. The height h is such that the animals cannot reach upper edge 4 with their paws. For pigs this may be for example 125 cm or in this order of magnitude. The diameter d in the case of pigs is for example 315 mm and the wall thickness f for example 5 mm. The bottom edge 5 of envelope 3 rests on and closes off the floor. Attached on the rear of envelope 3 is a bracket 6 of stainless steel, curved inward through a dimension k, so that the feed trough can be secured firmly by means of one central screw 8 and two support points 9. Envelope 3 is attached to the previously fastened bracket 6 by means of nut and bolt connections 10 at the location of the storage reservoir 11 which is encased by the upper part 12 of envelope 3. Storage reservoir 11 is closed off on its underside by closing means 13 comprising a curved closing partition 14 of plastic, for example PVC, a sloping part of which links up with a horizontal bottom part 16. The closing partition 14 is fastened for connection inside envelope 3, for example with bolted and/or adhesive joints.
Attached by means of two bolted joints 19 against the underside of bottom plate 16 around the passage opening 15 is the frame 17 of a feed delivery device 18. Frame 17 consists of a downward inclining baffle plate 20, a slightly sloping closing plate 21, two vertical sidepieces 22 with fastening edges 23, a curved sloping guide plate 48 and a bent front edge 24. Inserted through round openings 25 of sidepieces 22 is a shaft 26 to which a curved plate 27 is welded. This plate 27 comprises a discharge member 28 in the form of a downward directed strip, the bottom edge thereof brushing over closing plate 21.
A control plate 30 to be swivelled in the direction of arrow 29 by the snout of an animal is connected to discharge plate 28 since both form part of one and the same plate 27 pivoting around horizontal axis 31. Control plate 30 protrudes with end-pieces 33 sideways outside discharge member 28 to connect up to envelope 3 with a tolerance of about an inch, so that the animals cannot reach the rear part of control plate 30. Also for this purpose the end-pieces 33 have short curved top edges 34, control plate 30 connects at its top to upper edge 24 with a close tolerance, and control plate 30 has a bottom edge 35 that is curved round to the rear. Control plate 30 has
