AGROTECHNICAL AND ENERGY ESTIMATION OF EXPERIMENTAL WIDE-CUT SEEDING-MACHINE WITH ELECTRONIC CONTROL UNIT FOR THE GRAIN CROPS SEEDING PROCESS

Abstract

The development of the country's agro-industrial complex directly depends on the development of agricultural engineering industry. For which reason, the modernized agricultural machines are presently topical today for mastering advanced techniques of the agro-technologies in the agro-industrial complex. In the crop-growing sector of Kazakhstan for the production of high-quality ecological products that compete in the foreign market it is necessary to use digital technologies in agriculture. An analysis of advanced seeding machines suggests that there are seeders with designs that perform some technological operations with elements of automation. In this connection, the essence of our scientific research and the practical significance consists in the establishment of a “smart” seeder with an electronic control unit that solves complex problems: supporting two seeding modes; automatic control of the intensity of grain sowing depending on the speed of the tractor; automatic control of the intensity of fertilizer dispersion depending on the speed of the tractor and control of the filling of the bunker. When developing a wide-cut seeder with an electronic control unit, the basic principles of mechanical engineering technology and classical mechanics technologies were used; the working parts and components of the seeder were designed in Autodesk Inventor, and the electronic control unit was developed jointly with the POTTINGER Austrian company. In view of the foregoing, a wide-cut seeder with an electronic control unit for the process of sowing grain crops has been developed, consisting of a trailed module and a combined pneumatic mechanical system. In terms of quality, the developed experimental seeder meets the agrotechnical requirements for sowing grain crops under the conditions of Northern Kazakhstan and is quite competitive in the agricultural machinery markets.
