Abstract
The authors have developed a row-crop cultivator equipped with a ridge former, which allows performing high-quality operations of row crop cultivation in one pass. The inter row cultivation is carried out with a row-crop cultivator, on each section of which two ridge formers are mounted so that their flat discs are directed towards the row of plants at an acute angle, and the extreme edges of the wings of the V-shaped sweeps are located at the lower base of the soil ridge. When the row-crop cultivator moves, the V-shaped sweeps loosen the soil to the required depth and cut the weeds, and the flat discs move the soil layer coming off the wings of the V-shaped sweeps towards the rows of plants, hilling them and burying the weeds. In the presented article, the authors theoretically substantiate the angle of attack of a flat disc for burying weeds with a layer of soil of the required thickness. It was found that the angle of attack depends on the radius of the flat disc and the depth of its movement in the soil, the initial dimensions of the ridge and the physical and mechanical properties of the soil.
Highlights
Cultivating row crops according to the traditional cultivation technology provides for two or three times of inter row cultivation with row-crop cultivators that have special working bodies or spraying with chemical solutions - herbicides
The thickness of the layer h1, m, on the soil ridge depends on the angle of attack α, deg., flat discs, as well as the depth h, m, their travel in the soil (Fig. 3b)
Having substituted (8) and (12) into (7), we determine the area of contact of a flat disc with the soil: SUWZ = 0,5 rпд2 θ – rпд sin θ
Summary
Cultivating row crops according to the traditional cultivation technology provides for two or three times of inter row cultivation with row-crop cultivators that have special working bodies or spraying with chemical solutions - herbicides. The width of the protective zone is. Https://doi.org/10.10 51/matecconf /202134603102 increased with each subsequent tillage, as a result, the uncultivated area along the cultivated plants increases. The use of herbicides, in addition to the positive advantage - the elimination of weeds by 70 ... 80 %, has a negative side - a decrease in the yield of cultivated plants up to 15 % [1, 2, 3, 4, 5, 6] The use of herbicides, in addition to the positive advantage - the elimination of weeds by 70 ... 80 %, has a negative side - a decrease in the yield of cultivated plants up to 15 % [1, 2, 3, 4, 5, 6]
