ACTIVE SIDE DIVIDER OF THE COMBINE HEADER FOR HARVESTING PEAS

Abstract

The article concerns the problem of reducing losses during harvesting of tangled and dowm leguminous crops, particularly peas. This scientific research describes the proposed active side divider of the combine header made in the form of a disc cutter, which is mounted on the hydraulic motor shaft, and a counter-cutting plate fixed to the angled surface of the header sidewall. A methodology for determining the losses of the combine harvester header with the proposed active side divider has been developed. Also we have presented the results of laboratory and field studies to justify the design and operating parameters of the active side divider, conducted in accordance with GOST 28301-2015 "Grain harvesters. Test methods" on pea harvesting. After processing the experimental data, we obtained function equations and drew graphs of pea loss value dependencies on design and operating parameters of the active side divider. The findings have shown that the header with the proposed active side divider steadily performs the technological process at a disc cutter rotation frequency of n 120 min-1, a number of disc cutter teeth z – 8 pcs., and an operational speed of the combine v – 7 km/h. In this case, pea losses do not exceed the agronomic permissible losses.
