Abstract: The existing machinery for harvesting root crop and onions do not ensure high quality separation of root crop heaps which causes violation of the agroengineering standards during their harvest. To improve the quality of root crop separation, new solutions must be found, namely, increasing the separation completeness and reduction of damage. This study presents a laboratory equipment design that can determine intensity of separation of onion set trashed heap on a rod elevator. The study describes the research method and the experimental research results for onion set heap separation on a rod elevator. It shows the results of experimental research for a rod elevator in order to determine the intensity of onion set heap separation which can be used as input data for designing secondary separation equipment. It was found that the maximum intensity of onion set heap separation is 600 kg/sec with obtained optimum values of the considered factors: onion set heap feed = 24.8, ..., 28.8 kg/sec and the traveling speed of a rod elevator of 1.58, ..., 1.76 m/sec. The obtained experimental data will ensure designs of secondary separation machinery for onion set harvest both for the first and the second harvest stages and the high quality of the separation technical process.
