A control system for mixing materials for livestock feed including a container that receives the materials, agitators that mix the materials in the container, a driveline that drives the agitators at an output speed with an output torque, a power source that provides an input speed at an input torque, a continuously variable transmission that connects the driveline and the power source and having a hydrostatic loop to provide a speed ratio between the input speed and the output speed, a plurality of sensors positioned between the power source and the agitators that provides mixing signals commensurate to mixing parameters, and an electronic control unit configured to receive the mixing signals, extract mixing parameter values from the mixing signals, and actuate the continuously variable transmission and adjust the speed ratio based on the mixing parameter values to enhance efficiency of the mixing of the materials.

A transmission system for a feed mixer including a continuously variable transmission (CVT) is provided. The CVT includes a mechanical loop and a hydrostatic loop. The CVT is operated so that the mechanical portion of the CVT is prevented from overtaking the hydrostatic portion of the CVT at start up of the CVT.

A process for reliable detection of the top edge of the heading face of a pile of product(s) for animal feeding, from an extraction vehicle. It consists of positioning the vehicle in front of the heading face, then continuously controlling the upward motion of the extraction arm so as to vertically scan the plane of the heading face with the axes of measurement of at least two measurement sensors, then, as soon as at least any information is acquired indicating the absence of target, ordering the motion of the arm to stop, possibly ordering the detection of presence of an obstacle on the pile of product(s), then ordering the actuation of the extraction tool. Its object is also such a vehicle for implementing the process.

The invention provides a feed-mixing wagon (1) for animal feed, comprising a frame with a drive, a container (4) with a continuous wall (5) with a feed-unload opening, a feed auger which is arranged in the container for mixing and cutting animal feed and comprising an auger shaft (8) and an auger body (10) which is arranged around it in a spiral which has several blades, wherein the blades comprise at least one blade (11) of a first, long type and at least one blade (12) of a second, short type, and wherein at least one blade of the short type is situated closer to the bottom (6) than at least one blade of the long type. As a result of the various blades in the described configuration, the cutting and mixing behaviour can be adjusted in an optimum way.

A feed-mixing device for receiving, mixing and dispensing animal feed includes a frame with a mixing bin for receiving and mixing the animal feed therein and dispensing it therefrom, at least one mixing device rotatably drivable in the mixing bin using a drive, in particular a vertical mixing auger, for mixing the received animal feed, and a weighing device for determining the weight of the animal feed received in the mixing bin, comprising N weighing elements, with N≥2, each of which emits a weighing signal, and a control system for controlling the feed-mixing device and for processing the weighing signals from the weighing elements to produce the determined weight. The control system is configured to perform an, in particular fully automatic, calibration action of the weighing elements. The calibration action includes driving the at least one mixing device, reading out the respective weighing signal of each of the N weighing elements in each of M different positions of the mixing device, with M≥N, calibrating the weighing elements on the basis of the read-out weighing signals, wherein the calibrating at least includes determining a respective correction factor for the weighing signal of each weighing element by analysing the read-out weighing signals of all weighing elements. Thus, all weighing elements may be calibrated without having to detach the weighing elements, which provides very reliable weight measurements in a very simple manner.
