THEORETICAL JUSTIFICATION OF THE PARAMETERS OF THE COPYING CROP LIFTER OF A COMBINE HARVESTER HEADER

Abstract

The article deals with an important topic – reduction of grain losses during harvesting of lodged crops. It analyzes the designs of existing crop lifting devices for harvesting lodged crops and reveals their main drawback. The design and operating principles of the proposed copying crop lifter for combine harvester are described. The results of theoretical studies on justification of design parameters of copying crop lifter are given, in particular, theoretical dependencies determining the length of the slide and the base and the force required to match plated spring of the copying crop lifter are presented.
