Justification of the parameters of the lister body

Abstract

At present one of the leading places in the world is the development and mastering the production can simultaneously strip tillage and formation of irrigation throws and their use in the sowing of cucurbitaceous crops. The aim parameters the lister body combined strip-till of cucurbitaceous. Methods of classical mechanics have been applied in the research. In the process of research, the degree of layer turnover and soil crumbling by the lister body were determined, a special laboratory unit and strain gauge methods were used. Constructive the preparation fields from under cereals for strip sowing of gourds is the scheme with the lister body, ripper, right- and left-turning extreme bodies and furrow former located along the axis of symmetry. According to the results of theoretical studies, analytical dependences and mathematical models, allowing to determine the width of the lister body, the height of its blade, the size of the layer processed by the body, were obtained. Theoretical and experimental researches show that to provide the width of lister body should be 46 cm and its height 45.

Technology of ridge formation on cotton fields with simultaneous fertilization

“…To determine the reflection rate according to A.Kh. Khadzhiev and S. Khusainov [9], we plot the graphical dependence and find an empirical formula for different fertilizers: for ammophos…”

“…for ammonium nitrate V 0 = 0.027 T sub + 0.73 (10) where T sub is angle of incidence, deg; V 0 is reflection velocity, m/s. Using formulas (8), (9), and (10), let's determine the incidence angle, reflection angle, and reflection velocity for the above ten sites and plot the fertilizer reflection velocity (Table 2). Having an initial velocity equal to the reflection velocity, the fertilizer particle moves along the surface of the half-crown.…”

Parameters of the furrow cutter with levellers of the combined machine

“…b a = b T = 0,1 m. The length of the skimmer L k is the sum of the lengths of the lower (l1) and side (l2) edges of the skimmer, i.e. (6) The length of the lower edge of the flipper is equal to the following (7) Stipulate the long tipper according to next formula (8) . 2…”

“…Mamatov on investigating of process mutual influence machine-gun furrow, which prepares the soil for planting on the basis of advanced technologies for planting polys crops and its parameters F iviatov [1,2], B Mirzaev [3, 6-10, 12, 13, 21], N Aldoshin [8,22], Z Uzakov [16,20]. O Research works were carried out by F Mamatov [9][10][11][12][13][14][15][16]18, 25], B Tulaganov [9,12], S Toshtemirov [6,7] and others. In these studies, taking into account the soil-climatic conditions of the Republic of Uzbekistan, issuance of substantiate the argument furrow, which prepares the soil by turning it over and without turning it, preparing it for planting field crops in one pass, have not been sufficiently studied [1].…”

Placement of working bodies on the frame of the tool plow-ripper

“…As evidenced by domestic and foreign experience, chisel plows for non-moldboard soil are widely used. Promotes the preservation and concentration of humidity, improve processes of aeration infiltration, and avoid the growth of water and breeze erosion of soils [6][7][8][9][10][11][12][13][14][15]. A variety of chisel implements that provide a reduction in the degree of damage to the surface vegetation and a better leveling of the cultivated field are plows-rippers with racks of working bodies inclined in the transverse vertical plane F Maiviatov [1,2], I Ergashev [3], N Rashidov [5,8,21], B Mirzaev [6, 7-9, 12, 13], O Hamroyev [4,7], N Aldoshin [8,22], F Mamatov [3, 7-18, 20, 21, 24] and other songwriters.…”
