In the article the analysis of existing designs of flat-row separators is carried out. Hypotheses are put forward, which allow to eliminate existing disadvantages of constructions. Their essence is reduced to the feeding of grain perpendicular to the direction of air flow. This is provided by the slope of the walls of the aspiration canal at an angle close to 45°, so that the aspiration channel acquires the shape of a truncated hollow cone, coaxially inside a scattered installed, in the form of a truncated cone, which is turned with a larger base upward. The equation of regression of efficiency and clarity of the process of pneumatic separation from the regime parameters of the aspiration chamber is obtained. The regression equation of the purification and precipitation of light impurities has been obtained by an improved aspiration chamber.

The article presents the results of field experimental studies to establish the effect of the speed of displacement of the metering element on the probability of the appearance of gaps and twins when sowing seeds with a pneumatic-mechanical seeding device equipped with directional cells. The object of the study is a seeding device with a directional metering unit, an innovative design solution of which will improve agricultural production based on resource conservation. As a result of the use of a new constructive solution of the dispenser, the increased accuracy of the technological process of forming a regular single-grain flow of seeds.

“…The latter lead to an increase in inertial loads in comparison with their average values, which are determined by the laws of motion of an absolutely rigid body [6]. In the conditions of inconsistency of speeds of all or some elements of the car such sizes, as duration of the periods of start (acceleration) and braking [7], overload of the engine and transfers, can be defined only on the basis of dynamic calculations at which both instability of speed during movement [8], and inertia of masses, involved in the movement process [9].…”

Development of new steels in mechanical engineering to create alloys with predetermined properties that can minimize material and labor costs during their processing. Optimization of the chemical composition of the alloy based on the analysis of the impact of complex alloying on the structure and consequently on the manufacturability of steel. This will reduce the level of internal intensities in the heat treatment process. Based on the analysis of existing trends in mechanical engineering, it is established that the complexity of modern parts of gearweels imposes on the material increasing technological requirements for stamping, machinability, weldability, hardenability, cementation and gouging in the hardening process which explains the need for alloying steel via a certain group of chemical elements. The influence of different compositions of steels for gearweels on the level of internal intensities occurring in parts during heat treatment is studied. The optimal composition of complex-alloyed cementing steel is established.
