Studying of Energy Consumption of Multielement Combined Soil-cultivating Sowing Unit

Abstract

The paper investigates the power of functioning of the multielement combined soil-cultivating sowing unit. Energy expenses of tractor John Deere 8345R, the bunker for sowing material John Deere 1910 and seeder John Deere 1895 are calculated. Search of effective decisions of use of such units demands probe of power indicators of functioning and search of ways of power savings has been carried out. Increase of power efficiency of agricultural machinery and units is a challenge because of multigradualness of its structure and through a significant amount of the steered and uncontrollable indicators influencing process of functioning. A significant amount of designs of the combined multielement agricultural units demands creation of effective remedies and methods of probe of power expenses and not only for single-element cars. The variety of designs and layout schemes of units demands an estimation of influence of structure on power expenses. Probe of power of functioning demands the formation of energy-dynamic models of soil-cultivating sowing units. A tractor, a seeder and a bunker have a consecutive joint. Tractor wheels transfer energy from tractor transmission to its skeleton in parallel. As steering influences the angle of rotation of steered wheels of a tractor is chosen. Dispersal of the unit and steady movement on a rectilinear trajectory is investigated. For both modes of movement the seeder spends the greatest energy. At dispersal of the unit energy consumption by all elements raises linearly with corresponding increase of speed of movement to the worker. Block diagrams of investigated machines are formed of elements which settle down concerning others consistently, in parallel or with feedback. Scheme change of aggregation of units is flexibly investigated by means of change of a relative positioning of structural elements of energetically dynamic model.
