Abstract

A livestock feed wagon includes a frame, a feed container which is fitted on the frame, in particular provided with a feed mixer, a gripper construction having a movable arm construction and a gripper fitted thereon for grabbing an amount of animal feed from a pile of animal feed, and a weighing device. The weighing device is arranged and configured to weigh a grabbed amount of animal feed by determining a change in the weight of at least the feed container and the gripper construction with the grabbed amount of animal feed. As a result thereof, it is possible to determine both the total loaded weight in the feed container and the weight of a grabbed chunk of animal feed using the same weighing device, so that the chunk, if it is either too heavy or too light, can be returned prior being unloaded, if desired.

First claim

1 . A livestock feed wagon, comprising:
a frame; a feed container which is fitted on the frame; a gripper construction having a movable arm construction and a gripper fitted thereon for grabbing an amount of animal feed from a pile of animal feed; and a weighing device, wherein the weighing device is arranged and configured to weigh a grabbed amount of animal feed by determining a change in the weight of at least the feed container and the gripper construction with the grabbed amount of animal feed.

2 . The livestock feed wagon according to claim 1 , further comprising an intermediate plateau which is fitted between the frame on one side and the feed container and the gripper construction on the other side.

3 . The livestock feed wagon according to claim 1 , wherein the gripper construction is attached to the feed container.

4 . The livestock feed wagon according to claim 1 , further comprising a gripper control which is configured to control the gripper construction on the basis of the measured weight.

5 . The livestock feed wagon according to claim 1 , further comprising a 3D device for recording a spatial image containing distance information, wherein the 3D device is arranged on the gripper construction.

6 . The livestock feed wagon according to claim 5 , wherein the 3D device is configured to determine a volume of the grabbed amount of animal feed.

7 . The livestock feed wagon according to claim 5 , further comprising a memory for storing the weight of the grabbed amount of animal feed, and also of the determined volume of the grabbed amount of animal feed.

8 . The livestock feed wagon according to claim 5 , wherein the 3D device is configured to perform an analysis of a surface of the pile of animal feed which is situated in front of the 3D device, and wherein the gripper control controls the gripper construction on the basis of at least one of the analysis, the determined volume and the weight of the grabbed amount of animal feed, and the determined volume and the weight of a previously grabbed amount of animal feed.

9 . The livestock feed wagon according to claim 1 , wherein the gripper comprises two mutually pivotable gripping jaw halves or wherein the gripper comprises a movable blade for cutting a chunk of animal feed from a pile of animal feed, and also a movable support for supporting the chunk of animal feed.

10 . The livestock feed wagon according to claim 1 , further comprising:
one or more drives configured to drive the livestock feed wagon, a feed mixer provided in the feed container and/or the gripper construction; and a control for autonomously controlling the one or more drives.

11 . The livestock feed wagon according to claim 1 , wherein the feed container includes a feed mixer.

12 . The livestock feed wagon according to claim 11 , wherein the feed mixer includes one or more horizontal or vertical augers.

13 . The livestock feed wagon according to claim 1 , wherein the weighing device includes a plurality of load cells.

14 . The livestock feed wagon according to claim 2 , wherein the gripper construction is attached to the feed container.

15 . The livestock feed wagon according to claim 2 , further comprising a gripper control which is configured to control the gripper construction on the basis of the measured weight.

16 . The livestock feed wagon according to claim 3 , further comprising a gripper control which is configured to control the gripper construction on the basis of the measured weight.

17 . The livestock feed wagon according to claim 2 , further comprising a 3D device for recording a spatial image containing distance information, wherein the 3D device is arranged on the gripper construction.

18 . The livestock feed wagon according to claim 3 ; further comprising a 3D device for recording a spatial image containing distance information, wherein the 3D device is arranged on the gripper construction.

19 . The livestock feed wagon according to claim 4 , further comprising a 3D device for recording a spatial image containing distance information, wherein the 3D device is arranged on the gripper construction.

20 . The livestock feed wagon according to claim 6 , further comprising a memory for storing the weight of the grabbed amount of animal feed, and also of the determined volume of the grabbed amount of animal feed.
