Establishing theoretical regularities of oscillatory movements of the disc colter assembly of a direct seeding planter to justify its rational modes, which ensures high-quality sowing of seeds in the soil.\u0000Methods. During the research, methods of the theory of agricultural machines and modeling of technological processes performed by them, methods of higher mathematics, theoretical mechanics, as well as numerical calculations using a personal computer were used.\u0000Results. Compiled differential equations of translational and angular oscillations of the colter unit of the direct seeding planter, which arise under the action of reactions from the soil surface during the movement of the seeding unit along the unevenness of the field surface. The analytical solution of the specified differential equations made it possible to obtain expressions for calculating the frequencies and amplitudes of the studied oscillations depending on the structural and kinematic parameters of the colter unit and the parameters of the soil surface irregularities. On the basis of the obtained analytical expressions, graphical dependences of the amplitude of oscillations of the colter unit of the direct seeding planter on the speed of its translational movement with different stiffness of the springs of the double-spring suspension were constructed.\u0000Conclusions\u00001. A rational combination of the design parameters of the seeding unit, the speed of its translational movement, and the parameters of the unevenness of the soil surface, which achieve the necessary quality of seed sowing, is ensured by their determination using the obtained new analytical dependencies.\u00002. The obtained expressions for determining the amplitudes and frequencies of vertical oscillations of the colter assembly make it possible to minimize the magnitude of these oscillations and their impact on the quality of seed sowing.\u00003.

Experimental methods to estimate the flight range of mineral fertilizer granules, to determine the shape of the fertilizer scattering torch, to compare the results of practical research with theoretical calculations of the flight range.\u0000Methods. Full-scale experimental studies of a mock-up sample of a fertilizer spreader.\u0000Results. To improve the quality of sieving, a multi-disc device for sifting mineral fertilizers over the field surface is proposed. It is proposed to make the device in the form of independent, functionally independent modules. Each module consists of three independent units: a fertilizer tank with an agitator; horizontal disc dispenser with calibration holes; a horizontal spreader plate. Each of the modules is equipped with its own electric drive, allowing them to be individually adjusted to a specific operating mode. As a result of studies of a prototype dispenser with active forced-batch dosing of bulk mineral fertilizers, its satisfactory performance was obtained. This makes it possible to regulate the dosage of fertilizers on the spreading disc within the specified limits, and the range of spreading the fertilizers through the individual setting of a certain number of rotational speed of the spreading disc. This arrangement does not limit their number and attachment points on the frame, and the working width of the unit will be regulated only by their number and the range of fertilizer spreading by each individual block.\u0000Conclusions. The flight range of mineral fertilizer granules depends on the frequency of rotation of the spreading disc, its height above the surface of the field, and the coefficient of windage of the fertilizers.\u0000With a change in the location of the spreading disc height from 0.2 to 1 m, at a spreading disc speed of 46.6; 33.3; 50 s-1, the spreading range for granular superphosphate (double) varies from 1.56 to 7.65 m, granular superphosphate from 1.54 to 7.24 m, granular ammonium nitrate from 1.46 to 6 m. \u0000The flight ranges of pellets obtained by practical and theoretical methods coincide within the limits of the requirements.

To increase the degree of adequacy of the mathematical model of contact heating of seeds in a vacuum due to the refinement of the overall coefficient of thermal conductivity.\u0000Methods. The study of the mathematical model of the process of contact heating of seeds in vacuum was carried out using the methods of optical physics, planimetry, thermal physics. Mathematical dependencies were developed using algebraic transformations. The analysis of the obtained mathematical dependencies was carried out by the methods of technical analysis and graphic-analytical methods by comparing the graphs of the seed heating kinetics.\u0000Results. The total heat flow in the vacuum chamber, which exits the heating surface and is divided into two flows, has been studied, one of them transfers heat due to heat conduction through the touch of seeds with a heating surface and between themselves, and the second transfers heat through radiation in the cavities between the seeds. Calculation formulas for these heat fluxes have been developed, through which the formula for calculating the total thermal conductivity coefficient has been determined. This formula shows that the overall thermal conductivity is less than the theoretical value and depends on the equivalent seed diameter and seed characteristics.\u0000Conclusions. It has been established that the total thermal conductivity coefficient of seeds is less than the theoretical one due to voids between seeds, in which the heat of less heated layers propagates through radiation.
