Abstract

An unloading apparatus is arranged to direct material to a container. A controller determines a build-up speed of the material in the container; in accordance with the determined build-up speed, determine a rate of change to be applied when setting an attribute of at least one of the unloading apparatus and container; and set an attribute of at least one of the unloading apparatus and container in accordance with the determined rate of change in order to direct the material from the unloading apparatus to the container.

First claim

The invention claimed is:

1. An unloading system comprising
an unloading apparatus configured to direct material to a container that is movable relative to the unloading apparatus, and
wherein the controller is configured to:
determine a build-up speed of the material in the container;
in accordance with the determined build-up speed, determine a rate of change to be applied when setting an attribute of at least one of the unloading apparatus and the container;
set an attribute of at least one of the unloading apparatus and container in accordance with the determined rate of change in order to direct the material from the unloading apparatus to the container; and
wherein the controller is further configured to process the work of an engine associated with the unloading apparatus is doing, in order to determine the build-up speed of material in the container.

2. The unloading system of claim 1 , wherein the controller is further configured to process a material setting indicative of the type of material that is being unloaded in order to determine the build-up speed of the material in the container.

3. The unloading system of claim 1 , wherein the controller is further configured to process a measurement of fuel consumption of the engine associated with the unloading apparatus in order to determine the build-up speed of the material in the container.

4. The unloading system of claim 1 , wherein the controller is further configured to process a flow sensor signal in order to determine the build-up speed of the material in the container.

5. The unloading system of claim 3 , wherein the controller is further configured to process a travelling speed of a vehicle associated with the unloading apparatus in order to determine the build-up speed of the material in the container.

6. The unloading system of claim 3 , wherein the controller is further configured to process images of the material in the container in order to determine the build-up speed of the material in the container.

7. The unloading system of claim 3 , wherein the controller is further configured to determine a value for the build-up speed of the material in accordance with one or more measured parameters, and wherein the controller is configured to determine the rate of change in accordance with the determined value for the build-up speed.

8. The unloading system of claim 7 , wherein the controller is further configured to determine the value for the build-up speed of the material in accordance with an algorithm.

9. The unloading system of claim 3 , wherein the controller is configured to apply a material build-up control algorithm in order to determine the rate of change in accordance with the determined build-up speed.

10. The unloading system of claim 3 , wherein the controller is configured to use a look-up table or database in order to determine the rate of change in accordance with the determined build-up speed.

11. The unloading system of claim 1 , wherein the controller is operatively connected to the movable unloading apparatus of an agricultural harvesting machine, and the controller is configured to determine a rate of change to be applied when setting an attribute of the unloading apparatus.

12. An agricultural harvesting machine having a harvesting header and unloading system comprising:
an unloading apparatus connected to a frame of the harvester, the unloading apparatus configured to direct material to a container that is movable relative to the unloading apparatus, and
a controller configured to:
determine a build-up speed of the material in the container;
in accordance with the determined build-up speed, determine an adjustment to be applied when setting an attribute of at least one of the unloading apparatus and the container;
set an attribute of at least one of a position of a portion of the unloading apparatus with respect to the frame and container in accordance with the determined build-up speed in order to direct the material from the unloading apparatus to the container; and

wherein the build up speed of the material in the container is determined using a header usage parameter, wherein the header usage parameter is indicative of the amount of material entering the harvester and wherein the controller is further configured to process the work of an engine associated with the unloading apparatus in order to determine the build-up speed of material in the container.

13. A method of controlling an unloading system to direct material from an unloading apparatus associated with an engine to a container, wherein the unloading apparatus and container are movable relative to each other, the method comprising:
determining using a controller a build-up speed of the material in the container;
in accordance with the determined build-up speed, determining a rate of change to be applied when setting an attribute of at least one of the unloading apparatus and container;
setting an attribute with the controller of at least one of the unloading apparatus and container in accordance with the determined rate of change in order to direct the material from the unloading apparatus to the container; and,
determining the work of the engine to determine the build-up speed of material in the container.
