Abstract

Yield mapping technology is considerably well established for grain combines, but not as readily available other harvesting machinery; therefore, researchers have been developing systems to map crops other than grain. Moreover, cost effective alternatives of mapping systems are desired for lower cost harvesting machines such as the pull type dry edible bean harvester. Previous studies have presented low cost alternative for measuring torque on a drive chain driven shaft. This concept of drive torque measurement was implemented on a clean grain bucket elevator of a dry bean harvester, and evaluated as mass flow sensor. Tests were conducted in the Yield Monitor Test Facility (YMTF) of University of Kentucky following the recommendation of ASABE Standard S578. Device was tested within the flow rate range of 0 to 3.4 kg-s-1. At two standard deviation level, the deviation at 3.3 kg-s-1/ was ± 4.2% and the deviation at 1.6 kg-s-1 was ± 4%. The average accumulated mass errors were less than 3.1% and the maximum accumulated error was 4.9% at a flow rate of 1.8 kg-s-1.
