RESULTS OF LABORATORY INVESTIGATIONS OF SOIL SCREENING ABILITY OF A CHAIN DIGGER WITH ASYMMETRIC VIBRATOR ARRANGEMENT
Journal Title: INMATEH-Agricultural Engineering - Year 2019, Vol 57, Issue 1
Abstract
The increased yield of onion sets through the use of high-yielding hybrids as seed material entails an increase in weight and number of onion bulbs per one running meter. Consequently, the onion set heap supply from the surface of modern harvesters digging over the separating working parts is also increased. However, these harvesters do not ensure complete removal of soil impurities during onion set harvesting in the traditional onion set production conditions. In this regard, it is necessary to carry out investigations to identify areas on the surface of a chain digger with asymmetric vibrator arrangement and minimum value of soil screening, as well as to develop recommendations and proposals for their improvement. The paper describes a procedure and results of laboratory tests of a chain digger with asymmetric vibrator arrangement to determine soil screening ability on its surface. It was found out that the greatest value of the screened soil mass, regardless of the supply of soil impurities, was observed at the wave length attenuation section of the loaded strand in the chain digger due to elliptical vibrator impact relevant to the length of the chain digger L_EL=1020 mm. The paper provides the results of laboratory tests of a chain digger with asymmetric vibrator arrangement and determines the length-width soil screening relationship.
