“…Once used in a fractionation mode, the OZF cleaners sort out from the harvested mass more biologically defective, crushed and damaged grains and in husk, as well as weeds, than similar machines from the "Petkus" and "Cimbria" companies [12].…”

The paper presents the data of long-term research on the composition of harvested mass coming for post-harvest processing from grain harvesters, outlines possible ways to improve the technology of postharvest grain and seed processing. It proposes a number of engineering solutions and describes grain separators for sorting and grading all types of grain. A secondary aspiration channel with a double grain cleaning capacity and an installed pendulum valve was developed, providing high-quality cleaning of grain heaps in all types of processing and increases the sorting of biologically defective grain up to 20 %. Some solutions are proposed to reduce air and energy consumption by 20–30 % by mounting a sieve boot onto a corrugated elastic pneumatic cylinder and sequential use of air flow in a fractional separator for secondary cleaning of seeds, as well as a fundamentally new scheme of machines servicing air.

“…The quality of the grain obtained during harvesting depends on a number of factors: the physical and mechanical properties of the harvested crop, the design features of the threshing-separating device (TSD) its operating modes [12][13][14][15]. The results of studies on the qualitative composition of the grain heap obtained from grain harvesters with different types of TSDs are presented in Table 2.…”

Our own research and analysis of the literature cited in the work have identified a number of different factors that affect the quality of the harvested grain. The paper provides an assessment of the influence of such indicators as the physical and mechanical properties of the harvested crop, the design features of the threshing-separating devices, the relative humidity of the processed heap, the size of the openings of the screens of the separating device. Studies carried out for machines with various types of threshing and separating devices have shown the advantage of rotary machines. The heap obtained on them with minimal contamination contains 2.2 times less crushed grain and 1.5 times more grain with the film. The sowing qualities of seeds, both germination energy and laboratory germination, are higher than those of seeds obtained from combine harvesters with a classic threshing-separating device. Investigations of the distribution of the components of the grain heap coming from the combine harvesters were carried out at five different moisture levels of grain on sieves with a hole width of 2.0 to 3.2 mm. The experimental results showed that the relative humidity of the grain does not significantly affect the distribution of the grain heap. At the same time, studies have shown that the bulk of the heap entering post-harvest processing in a grain cleaning machine is allocated on sieves with a hole diameter of 2.4–3.0 mm. The largest amount of whole grain is allocated on sieves 2.4–3.0 mm. With an increase in the grain moisture content of the initial heap from 14.1 to 18.9% and the size of the sieve openings from 2.0 to 3.2 mm, an increase in the amount of grain with the film is observed. The results presented can be used in organizing the activities and substantiating the design and technological schemes for post-harvest grain cleaning.

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.
