Improving combine harvester productivity as the main factor of increasing the economic efficiency of grain-harvesting process

Abstract

The research of the topical issue related to the improvement of air-sieve cleaning separation of the modern high-producing combine harvester is presented in the article. The calculation of economic efficiency of equipping combines with the suggested pneumatic and inertia separator is conducted in the paper. Research presented indicates the estimated efficient functioning of the cleaning design for small grain heap which helps to reduce grain losses and leads to the increase of combine harvester productivity.
