Amosov V. Substantiation of the parameters of the universal seedmeter for the tilled crops.

Research object - process of dosage and sowing of seeds of the cultivated cultures. The purpose of work is expansion of functional possibilities of sowing vehicle and rise of exactness of sowing of the cultivated cultures. Research methods. At the analysis of influencing of sizes of the suction opening on effort which attracts a seed to opening, the method of indignations is used. The ground of form and sizes of surface of reflector of superfluous seeds is conducted by means mathematical vehicle of differential geometry. The analysis of co-operation of seed with the surfaces of the suction opening of a different form is executed by the methods of analytical mechanics. Planning of experiment and regressive analysis are used for conducting and treatment of results of experimental researches. In work the dependences for determination of diameter of the suction opening of pneumomechanical sowing vehicle depending on the diameter of seed are shown out, conformity to the law of co-operation of spherical seedwith the surfaces of the suction opening of cylindrical, conical and tore form is set, analytical communication between the sizes of seeds and form and sizes of reflector of superfluous seeds is got, motion of seed is explored at the separation from the suction opening and the rational form of his surface is definite. Job performances are accepted to introduction on VAT "Red star", Kirovograd. A sowing technique and cultivated planters is the sphere of the use, in particular.
