Optimization of the main parameters of the support-lump-breaking coil

Abstract

Agricultural land plays an important role in ensuring food security and employment in rural areas. For many years, the planned economy has forced Uzbekistan to grow water-intensive crops, which has led to declining land productivity and increased crop yields. In a market economy, new innovative technologies are in high demand not only in agriculture but also in other sectors. In order to solve the above-mentioned problems, our research has found it necessary to set goals and objectives. The purpose of the study was to substantiate the parameters of frontal plowing slope, which provides high-quality execution of the technological process in accordance with the agro-technical requirements with minimum energy consumption without furrow plowing, agrotechnical and energy performance of variable frontal forks. The following results were achieved by performing the tasks identified in the study: a – humidity V=16–17 % and load conditions with elastic rods of 3 mm, 4 mm, 5 mm; b – humidity V=13–14 % and the diameter of elastic rods is 3 mm, 4 mm, 5 mm; c – humidity V=9–10 % and the diameter of the elastic rods is 3 mm, 4 mm, 5 mm. The experiments were performed on lumps with different humidity conditions: 9–10 %, 13–14 % and 16–17 %. The speed of the installation was 1.0 m/s. The recommended technology was to destroy soil fragments with a moisture content of 16–17 % at a vertical load of 400 N with 3, 4 and 5 mm elastic rods at 86.6, 81.5, 75.1 %, respectively, and the vertical load equal to 1,000 N – 94.4, 89.2, 81.2 %, respectively
