CLASSIFICATION OF DISC COULTERS ACCORDING TO TECHNOLOGICAL AND DESIGN PARAMETERS

When cultivating agricultural crops, pre-sowing tillage and sowing are of primary importance. The quality of these operations is determined by the choice of technological means and technical condition, adjustment and alignment, as well as compliance with all the agrotechnical requirements. Nowadays foreign and local seeding machines are often equipped with disc combined coulters. These units allow to combine operations of soil preparation, intrasoil application of initial dose of phosphorus fertilizers and sowing of agricultural crops. This article presents structural and morphological classification of coulters in 2 basic, 12 constructive and 6 engineering features. Application of this classification table is presented for description of purpose and characteristics of sowing operating units, as well as formation of digital indication record for them. The possibility of reproducing digital information about seeding operating unit in the form of variety of its characteristics is considered under specific examples of the existing combined disc coulters. The advantage of this classification table in comparison with the available ones is that its structure and form allow to easily supplement the features characterizing the studied operating unit without changing the algorithm for digital code generation. The proposed classification of combined disc coulters will contribute to a deeper solution of problems of synthesis and analysis of these operating units, will allow to use the digital coding to describe the entire diversity of features thereof.
