Abstract
Tillage is considered to be the methods of mechanical impact on the soil, contributing to the improvement of its fertility and the creation of better conditions for the growth and development of plants. Layerless processing without cover takes one of the most significant operations carried out during the preparation of the soil. This is confirmed by the fact that layer-by-layer processing promotes the accumulation of moisture inside the soil layer, the separation of the seam into layers, and the reduction of soil erosion. The aim of the research is to improve the design features of the main elements of the working body for layer-by-layer soilless tillage. Based on the methods of analysis and synthesis of research, as well as modeling, an improved design of the working body was proposed. It provides for the possibility of replacing almost all the main elements as they wear out, which in turn indicates a high level of wear resistance of the developed structure and a significant reduction in labor costs during its maintenance. In addition to the use of metal basic elements of various shapes (flat-cutter, curvilinear ripper) in the design of the working body, the use of ultra-high-molecular polyethylene inserts partially or completely replacing the main structural elements of the working body is also provided. Experimental studies have found that the traction resistance of the working body using a flat-ripper in the construction is 9,30 kN, with a curvilinear ripper 8,04 kN, which is 13,56 % lower than the flat-cutter. With the use of ultra-high molecular polyethylene inserts, a decrease in traction resistance of up to 7,6 kN was observed, which is 18,28 % lower compared to a flat-ripper. The proposed design allows layer-by-layer soilless tillage, carrying out at the same time a deep 25-35 cm and shallow 12-16 cm tillage, and also allows to obtain an aligned field background after the passage of the unit.
