A livestock feed wagon includes a moving frame, a feed container which is fitted on the frame for accommodating animal feed, in particular provided with feed mixer, and a movable arm construction having an operable gripper fitted thereto for grabbing an amount of animal feed. The arm construction is configured in such a way that the arm construction can pivot the gripper only in one plane from a first position for grabbing animal feed next to the livestock feed wagon to a second position for releasing the animal feed above the feed container. This makes it possible to provide a very simple and compact construction.

The invention provides a mixer feeder (1) comprising a mobile chassis (3), a tub (4) provided on the chassis (3) and at least one auger provided for rotation about a respective vertical axis of rotation. in the tub (4). Seen in vertical cross-section, the wall (12) of the tub (4) extends at least substantially upright from the bottom (6) of the tub (4). The wall (12) of the tub (4) curves inward at the upper side of the tub (4), sloping up and then extending downward.

A feeding system for feeding animals, in particular cows, includes a feed storage system for keeping feed for the animals in store, and a feed loading device for loading a batch of feed from the feed storage system into a receptacle of an autonomous feeding device in order to teed the animals. The feed loading device is provided with a feed grabber including two grab buckets which are hingeable between an open position and a closed position. The feed grabber includes an actuation device for actuating the grab buckets from the open position to the closed position. The actuation device includes a rotatably drivable winding-up body which is connected to one of the grab buckets and includes a winding circumference, and an arm which is connected between the winding-up body and the other grab bucket. The arm includes a plurality of mutually, hingeably connected arm sections which are made from stainless steel or a material having substantially the same strength and corrosion-resistant properties as stainless steel. The arm sections, in the open position of the grab buckets, extend substantially in line with one another. The arm sections, from the open position of the grab buckets, when the winding-up body is rotatably driven, are wound about the winding circumference of the winding-up body in order to pull the grab buckets towards the closed position. The arm sections are configured in such a way that the winding circumference of the winding-up body can be covered substantially in its entirety by at most 8 arm sections, preferably at most 6 arm sections, in particular 2 or 3 or 4 or 5 arm sections.

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.

The present invention is directed generally to a demountable silo (10) comprising a series of interconnected silo modules (12A to 12F) constructed in accordance with a preferred embodiment of this invention. The silo modules such as (12A) are each of a substantially identical configuration and interconnected in a side-by-side and end-to-end relationship. The demountable silo (10) is designed to contain particulate material and configured depending on the nature of the material and its storage requirements. It will be appreciated that the provision of multiple silo modules such as (12A to 12F) together contains significantly more particulate material in a heap than a single silo module. The maximum storage capacity for the demountable silo (10) is determined largely by the angle of repose of the heaped particulate material.

An extractor apparatus for moving grain from a grain bag has a frame mounted for movement along the ground in a rearward direction, and an upright oriented main auger attached to a rear end of the frame. A knife extends rearward from the main auger to cut the grain bag. A feed auger extends horizontally right and left of the intake end of the main auger, and is configured to auger grain to the intake end of the main auger. A disintegrator shaft is mounted rearward of the feed auger and parallel to the feed auger, and a plurality of disintegrator blades are spaced along a length of the disintegrator shaft and extend outward from the disintegrator shaft. A drive system is operative to rotate the main auger, feed auger, and disintegrator shaft. The length of the disintegrator shaft can be adjusted to suit the width of a particular bag.

A system for filling a feed mixer, the system comprising: a feed intake device configured to take in a feedstock from a stockpile; a feed processing system for processing the feedstock and directing the processed feedstock into a container of the feed mixer; and a controller associated with the feed processing system, the controller configured to control processing of the feedstock by the feed processing system based on a prescribed recipe.
