Foreign Body Detector For An Agricultural Harvester
First Claim
1. A foreign body detector for an agricultural harvester, comprising a sensing element fitted such that it is movable transversely to a direction of conveyance of a crop and which, during the harvesting operation, bears against the received crop, wherein the foreign body detector comprises a position sensor set up to register the position of the sensing element, and an evaluation circuit, which can be operated to calculate on the basis of the signals of the position sensor information relating to at least one of the velocity or acceleration of the sensing element and, for the purpose of generating a signal value indicating the presence of a foreign body, to make a comparison with a threshold value.

Abstract
A foreign body detector for an agricultural harvester is provided having a sensing element which is fitted such that it is movable transversely to a direction of conveyance of the crop and which, during the harvesting operation, bears against the received crop. The foreign body detector has a position sensor set up to register the position of the sensing element, and an evaluation circuit, which can be operated to calculate, on the basis of the signals of the position sensor, information relating to the velocity and/or acceleration of the sensing element and, for the purpose of generating a signal value indicating the take-up of a foreign body, to make a comparison with a threshold value.
