Comb Former Parameters for a Cotton Seeder

Abstract

Success in cultivating cotton largely depends on the timing and quality of soil preparation for sowing and sowing, and the latter, in turn, depends on how it is carried out and on the perfect design of the machines. The aim of the study is to justify the shape of the ridges and the parameters of the moulder to the cotton seeder. The authors proposed a new technology for sowing with the simultaneous formation of ridges. The shape and parameters of the ridge are theoretically substantiated. When performing the shape of the ridge in the form of an isosceles trapezoid and, accordingly, with a height and width of the ridge surface of at least 100 mm and 160 mm, the seed bed is protected from flooding by rain streams. The design of the developed comb moulder to a cotton seeder for the implementation of the proposed technology is given. Theoretically substantiated the main parameters of the crest moulder. It was found that when the input edge of the moulder is 290-320 mm wide, the output edge is 160 mm, the angle of inclination of the side blade to the direction of movement is 20°, the length of the runner of the moulder is 203-215 mm, the height of the side blade is 100 mm and the angle of installation of the side blade to horizon 42-45° ensures highquality implementation of the technological process of formation of ridges. When sowing cotton seeds on the ridges with the simultaneous formation of the ridge, the seedlings of the plants increase, and the cotton yield increases compared to the smooth sowing method of 9.9%.

Technology and machine parameters for preparing the soil for sowing cotton

“…At a p =0,45 m, h n =0,15 m, l n =0,26 m, and ψ 1 =40º by expression (7), the longitudinal distance between subsoilers should be no less than 0,375 m.…”

“…Research on creation and application of machines for tillage and preparation of soil for seeding on ridges, study of their performance and justification of parameters, as well as study of processes of interaction of working bodies with soil were carried out by F.Mamatov [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16], [18][19][20][21][22][23], [28][29], B.Mirzaev [5][6][7][8][9][10][11][12], [14][15][16][17][18][19][20][21], [23], [28][29] U.Umurzakov [4,19], N.Aldoshin [3,10,11,19,20,…”

Traction resistance of the combined machine plough

“…Soil deepeners designed for subsurface loosening of the soil are widely used on plows [1][2][3][4][5][6][7][8][9][10][11], combined tillage machines . As a result of the subsurface loosening of the soil, the most favorable conditions are created to grow and develop plant roots.…”

Ripper for processing slope fields

“…It is relevant to conduct targeted scientific research on the development of dump and non-dump anti-erosion working bodies, ensuring resource conservation in the processes of their interaction with the soil. Research on the development and application of machinery to protect the soil from water and wind erosion, in particular machinery working bodies of the "paraplu", studying their performance and justification of the parameters studied F.Mamatov , B.Mirzayev [4][5][6][7][8][9][10][11][12][14][15][16][17][18][19][20][21][22][23] V.Alexandrian [28], A.Vagin [29], N.N.Nagorny [30], V.Svetlichniy [30], V.M.Drinca [32], D.A.Tryapitsyn [34], Pazova T [33], B.Borisenko [32] and others. The machines and tools created as a result of these studies are used with certain positive results in the tillage of the slopes.…”
