Abstract
The purpose of the study is to substantiate the design scheme and parameters of the working bodies of a combined machine for tillage and sowing grain on sloping lands. The authors have developed a machine that performs technological operations for tillage, grain sowing, and ridge formation to prevent water erosion. The design diagram is given. The basic principles and methods of classical mechanics, mathematical analysis, and statistics were used in this study. Theoretical and experimental studies have established that using a chisel-shaped ripper with loosening knives as a loosening working body provides high-quality loosening of the soil. When the longitudinal and transverse distances between the rippers are 62.5 and 15 cm, respectively, the longitudinal distance between the rear ripper and the housing is 60 cm, and the transverse distance between the buildings is 90 cm, high-quality soil loosening, and grain sowing are achieved with minimal energy consumption.
Highlights
Great attention is paid to the development of combined machines for water and wind erosion tillage [28] and soil erosion tillage and sowing in one pass from the field [29]
It is necessary to develop machines equipped with working bodies that form ridges at the bottom of the slope and on the field surface, which protect sloping soils from water erosion [30]
(1) We find that the longitudinal distance between the softeners casting the values l0 = 16.7 cm, lt = 10 sm φ = 25o [34], αi = 30o, known to the expression, must be at least Li=62.45 cm
Summary
The development and application of energy-efficient, labor-intensive, and combined machines for pre-sowing tillage is a world leader [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27]. Great attention is paid to the development of combined machines for water and wind erosion tillage [28] and soil erosion tillage and sowing in one pass from the field [29]. It is important to develop machines and justify the technological process for planting and ensure resource efficiency in the interaction of working parts with the soil [29]. For this reason, it is necessary to develop machines equipped with working bodies that form ridges at the bottom of the slope and on the field surface, which protect sloping soils from water erosion [30]
