Abstract

An animal feedstuff processing system for processing animal feedstuff includes an animal feedstuff storage device for storing a pile of animal feedstuff, a separating device for removing a quantity of feedstuff from the pile and including a rotatable separating element and a first drive for the separating element, a movement device with a second drive, and configured for moving the separating device and the pile of feedstuff towards each other. A sensor is arranged for determining a relative position of the separating element with respect to the pile of feedstuff. A controller is configured to control the animal feedstuff processing system. During at least a part of the movement of the separating device and the pile of feedstuff towards each other, the separating device is driven in an idle mode by the first drive, wherein the separating element has no operable contact with the pile of feedstuff. The sensor measures a sensor signal representative of an operating parameter of the first drive, and the controller is configured to determine contact between the separating element and the pile of feedstuff based on the sensor signal. The animal feedstuff processing system is controlled on the basis of the determined contact.

Dependent claims

A feed-processing system for processing animal feed, comprising:

a feed storage bin for storing a pile of animal feed;
a remover for releasing an amount of animal feed from the pile of animal feed in the feed storage bin, the remover comprising a rotatable removing member and a first drive for the rotatable removing member;
a displacer with a second drive, the displacer configured to move the remover and the pile of animal feed towards each other;
a sensor for detecting a first sensor signal;
and
a control unit configured to control the feed-processing system,
wherein the control unit is configured to cause the first drive to drive the rotatable removing member in a freewheeling mode during at least a part of the movement of the remover and the pile of animal feed towards each other, wherein the rotatable removing member is not in any operative contact with the pile of animal feed,
wherein the sensor measures the first sensor signal relating to a first operating parameter of the first drive,
wherein the control unit is configured to:
detect whether the rotatable removing member and the pile of animal feed are in contact on the basis of the first sensor signal;
control the feed-processing system, partly on the basis of whether or not contact is detected;
and
cause the first drive to drive the rotatable removing member in a removing mode when the control unit has detected said contact, wherein the rotatable removing member releases animal feed and removes it from the pile of animal feed, and wherein the first drive operates at a higher rotary speed and/or power than in the freewheeling mode,
wherein the feed storage bin comprises a storage floor in a fixed position with respect to the outside world,
wherein the remover comprises a displaceable vehicle which carries the rotatable removing member, and
wherein the vehicle is autonomously self-propelled.
