Simulating the Process of Vertical Tillage with a Turbo-Disc Cultivator for the Territories of Crimea

Introduction. A promising means for cultivating the arable layer is vertical tillage using agricultural machinery with disc working tools. This agricultural machinery is used to crush and partially embed plant residues into the soil with minimal soil damage that results in increased yields. However, there have not enough studies been conducted on simulating the vertical tillage process using a turbodisc cultivator. Aim of the Study. The study is aimed at simulating the process of vertical tillage with a developed turbodisc cultivator to increase the cultivator performance. Materials and Methods. The object of the study is the upgraded turbo-disc cultivator (RF Patent No. 2825223). The research method is based on the principles of theoretical mechanics and mathematics. There was used the Cochran criterion to confirm the reliability of the obtained dependences of the cultivator performance on the number of waves on a wave disc at a speed of 18 km/h and needle lengths of 0.2565 and 0.3195 m. Results. There is presented a block diagram of algorithms for vertical tillage with a developed turbodisc cultivator and the cultivator performance optimization. There have been found the projections of the point velocity. Discussion and conclusion. When the the tractor-machine unit speed is of 15 km/h, the needle length is 0.2565 m and the wave disc diameter is from 0.343 to 0.559 m, the productivity increases from 3.72 to 4.37 ha/h with 4 blades on the needle disc, from 5.46 to 6.41 ha/h with 6 blades and from 7.20 to 8.45 ha/h with 8 blades. The practical significance of the research is the substantiation of the rational performance of the turbo-disc cultivator for vertical tillage, as well as the block diagram of the algorithm, which will allow you to choose the optimal performance of the turbo-disc cultivator under various regime indicators and design parameters of the needle and wavy discs. The prospects of the research are the development and search for new technical solutions to improve the design of the working bodies of the turbo-disc cultivator, which will reduce its energy consumption and increase its productivity.
