Development and Modeling of an Onion Harvester with an Automated Separation System

One of the most important problems during implementation any technology is to reduce labor costs, energy, and resource conservation while increasing yield cultivated crops and, as a result, reducing cost production. Despite significant amount scientific research devoted problem energy in cultivation harvesting agricultural development mechanization tools that ensure high-quality performance technological operations, there remain issues have not been fully resolved date. In addition, all results known theoretical experimental studies can be directly applied intensify process root since quality indicators marketable products depend on type parameters separating working bodies. This article presents design rod elevator with an adjustable angle inclination web, which reduces damage commercial bulbs maximum completeness separation. A laboratory facility has developed substantiate system web angle. Based studies, machine for onions blade developed, provides increase onion at optimal values parameters: (1) translational speed movement 1.7 m/s 98.4% separation 1.7% bulbs; (2) 1.0 98.5% 1.1% (3) digging depth plowshare equal 0.02 m, heap more than 98% product less 1.4%. The its interaction are presented. Basic studied substantiated, namely, distance S1 actuators, a1 longitudinal surface relative horizon, differential equations motion onion-sowing pile element web.
