AGRICULTURAL CENTRIFUGAL SPREADER AND METHOD FOR DETERMINING THE SPREAD PATTERN OF AN AGRICULTURAL CENTRIFUGAL SPREADER

摘要

Agricultural centrifugal spreader (1) with two spreading discs (2.1, 2.2) and in each case at least one sensor (10.1, 10.2), preferably radar sensor, per spreading disc to determine the mean throwing distance (MW1, MW2) of the spreading disc, the sensors being arranged on the spreader that the throwing distance measurement is carried out at a distance from the spreading discs of the centrifugal spreader at which there is a significant overlap of the spreading areas (15.1, 15.2) of the two spreading discs. In order to provide a centrifugal spreader with which an improved setting of a desired spreading pattern is possible that the measuring directions of the at least two sensors in the horizontal plane are aligned at least approximately in the direction of the mean throw angle (MA1, MA2) of the respective spreading disc. In addition, a method for determining the spreading pattern in an agricultural centrifugal spreader is provided in which to reduce the Influence sses of wind strength and / or wind direction on the determination of the spread pattern, a determined first variable (MW1) and at least one second determined variable (MW2) is taken into account.
