Abstract

A feed-mixing wagon includes a container for receiving feed. The container includes a bottom, and a peripheral wall which is closed off at a bottom end by the bottom. A mixing element is provided for mixing the feed to be accommodated in the container. The peripheral wall is provided with a wall covering which extends at least along a bottom, ring-shaped part of the inner surface of the peripheral wall. The wall covering includes a plurality of wall plate parts with upwardly extending side edges. Two adjoining side edges of at least two respective adjoining wall plate parts are clamped to the inner surface of the peripheral wall by clamping strips which overlap these adjoining side edges and which are attached to the peripheral wall of the container by means of detachable fasteners.

First claim

The invention claimed is:

1. A feed-mixing wagon, comprising:
a container for receiving feed, the container being provided with a bottom and a peripheral wall that is closed off at a bottom end thereof by the bottom, wherein the container is provided, at a top end situated opposite the bottom, with a supply opening for supplying feed to the container, wherein the bottom and the peripheral wall each comprise an inner surface extending in the container, wherein the peripheral wall is provided with a wall covering extending at least along a bottom, ring-shaped part of the inner surface of the peripheral wall, and wherein the wall covering comprises a plurality of wall plate parts; and
a mixing element for mixing the feed accommodated in the container, the mixing element being fitted in the container so as to be drivable and rotatable about a substantially vertical rotation axis,
wherein the wall plate parts each comprise two upwardly extending side edges, and wherein the wall plate parts are arranged with the extending side edges adjoining each other, and wherein two adjoining side edges of at least two respective adjoining wall plate parts are clamped against the inner surface of the peripheral wall by clamping strips that overlap the adjoining side edges and that are attached to the peripheral wall of the container by detachable fasteners.

2. The feed-mixing wagon according to claim 1 , wherein the bottom is provided with a bottom covering extending substantially across an entire inner surface of the bottom, and wherein the bottom covering comprises at least one bottom plate part releasably attached to the bottom of the container.

3. The feed-mixing wagon according to claim 2 , wherein each of the clamping strips is provided with a stop face at a bottom end thereof, and wherein the at least one bottom plate part of the bottom covering is retained in a height direction between the stop face of the clamping strip and the bottom for securing the bottom covering in the height direction.

4. The feed-mixing wagon according to claim 3 , wherein the bottom covering comprises a plurality of bottom plate parts arranged such that the bottom plate parts adjoin each other and wherein each bottom plate part is provided with at least one recess situated adjacent to the peripheral wall of the container, and wherein a bottom end of the clamping strips extends into the recesses of the bottom plate parts, wherein said bottom end is provided with two lateral stop edges which, viewed in a peripheral direction, extend on either side of a respective clamping strip in order to secure the bottom plate parts in the peripheral direction, and wherein each of the bottom plate parts is retained in the height direction between the stop faces of the clamping strips and the bottom in order to secure the bottom plate parts in the height direction.

5. The feed-mixing wagon according to claim 4 , wherein the clamping strips that extend into the recesses of the bottom plate parts with bottom ends of the clamping strips thereof each comprise a lateral projection protruding in the peripheral direction above the bottom plate parts so as to form the stop face of said clamping strips in order to secure said bottom plate parts in the height direction.

6. The feed-mixing wagon according to claim 4 , wherein the bottom plate parts each comprise two corners arranged adjacent to the peripheral wall, and wherein the bottom plate parts in each case comprise a corner recess on the corners, and wherein the corner recesses of, in each case, two adjoining bottom plate parts together, in each case, form a compound recess, into which the clamping strips extend with a bottom end thereof, and wherein each of the bottom plate parts is retained in the peripheral direction between two lateral stop edges of two different clamping strips in order to secure the bottom plate parts in the peripheral direction.

7. The feed-mixing wagon according to claim 6 , wherein the clamping strips that extend into the compound recesses with the bottom ends of the clamping strips thereof each comprise two lateral projections protruding on either side of the respective clamping strips in the peripheral direction above, in each case, two adjoining bottom plate parts so as to form the stop faces of said clamping strips in order to secure said bottom plate parts in the height direction.

8. The feed-mixing wagon according to claim 1 , wherein the wall plate parts and/or the clamping strips are made of stainless steel.

9. The feed-mixing wagon according to claim 1 , wherein the bottom of the container and/or the peripheral wall of the container are made of low-carbon steel with a carbon content of less than 0.3%.

10. The feed-mixing wagon according to claim 1 , wherein the fasteners, by which the clamping strips are attached to the peripheral wall of the container, comprise bolt/nut connections, and wherein the bolts of the bolt/nut connections extend through first securing holes in the clamping strips and through second securing holes provided in the peripheral wall and aligned with the first securing holes, and wherein the side edges of the wall plate parts are arranged substantially adjacent to the second securing holes in order to form a seam between, in each case, two adjoining wall plate parts, and wherein said seams are substantially completely covered by the clamping strips.

11. The feed-mixing wagon according to claim 1 , wherein the peripheral wall of the container comprises two substantially flat parts connected to each other by a weld seam, and wherein the fasteners, by which the clamping strips are attached to the peripheral wall of the container, comprise bolt/nut connections, and wherein the bolts of the bolt/nut connections extend through first securing holes in the clamping strips and through second securing holes provided in one of the flat parts next to the weld seam and aligned with the first securing holes.

12. The feed-mixing wagon according to claim 5 , wherein each of the bottom plate parts comprises a radial projection that cooperates with the lateral projection of the clamping strips.

13. The feed-mixing wagon according to claim 12 , wherein the bottom and the peripheral wall of the container are connected to each other by a continuous weld seam, and wherein the radial projection is provided with a slanting bottom edge in order to form a receiving space underneath the bottom plate parts for a part of the continuous weld seam.

14. The feed-mixing wagon according to claim 1 , wherein the wall covering is provided with a moisture-proof seal provided between the wall plate parts and the peripheral wall of the container.

15. The feed-mixing wagon according to claim 14 , wherein the moisture-proof seal of the wall covering comprises a plurality of continuous, moisture-proof strips, each being arranged between, in each case, one of the wall plate parts and the peripheral wall of the container and each of running at a distance from and substantially parallel to the edge of said wall plate part.

16. The feed-mixing wagon according to claim 2 , wherein the peripheral wall of the container comprises a lateral discharge opening that is closable by a hatch, wherein the discharge opening is provided with two substantially vertical side edges and an intermediate bottom edge substantially in one plane with the bottom of the container, and wherein at least one bottom plate part comprises a protruding edge part protruding above the bottom edge of the discharge opening wherein said protruding edge part is provided with two stop edges which, viewed in a peripheral direction, extend on either side
