Abstract
A sensor arrangement for detecting properties of a mixture including grain and contaminants in a cleaning device of a combine harvester. The sensor arrangement is equipped with a sensor element for providing an output signal in respect of a property, detected by the sensor element, of the mixture adjacent to the sensor element. The sensor element is configured to be brought operationally continuously in succession into different positions in relation to the mixture in order to sense different points of the mixture in the different positions of the sensor element.
Claims14
A sensor arrangement for detecting properties of a mixture including grain and contaminants in a cleaning device of a combine harvester, the sensor arrangement comprising:
- a sensor element for detecting a property of the mixture adjacent the sensor element, the sensor element providing an output signal based on the property, wherein the sensor element interacts with the mixture on a conveying device, and wherein the sensor element is configured to be brought operationally continuously in succession into different positions in relation to the conveying device in order to sense different points of the mixture in the different positions of the sensor element,
- wherein the different positions of the sensor element in relation to the conveying device are achieved by a movement of a driven element of the cleaning device on which the mixture is processed, and
- wherein the sensor element is mechanically coupled to the driven element and to a chassis, and an oscillating movement of the driven element is mechanically converted into a movement of the sensor element in relation to the driven element, and in relation to the conveying device.
A cleaning device of a combine harvester, comprising;
- a sensor arrangement for detecting properties of a mixture including grain and contaminants in the cleaning device, the sensor arrangement further including:
- a sensor element for detecting a property of the mixture adjacent the sensor element, the sensor element providing an output signal based on the property, wherein the sensor element interacts with the mixture on a conveying device, and wherein the sensor element is configured to be brought operationally continuously in succession into different positions in relation to the conveying device in order to sense different points of the mixture in the different positions of the sensor element
- wherein the different positions of the sensor element in relation to the conveying device are achieved by a movement of a driven element of the cleaning device on which the mixture is processed, and
- wherein the sensor element is mechanically coupled to the driven element and to a chassis, and an oscillating movement of the driven element is mechanically converted into a movement of the sensor element in relation to the driven element, and in relation to the conveying device.
