Study on plowing of cotton soil using two-tier plow

Abstract

The purpose of the study is to substantiate the parameters of a two-tier plow for plowing soil from under cotton. The basic principles and methods of classical mechanics, mathematical analysis and statistics were used in this study. The effects of the cotton field relief on the tillage and traction resistance of a two-tier plow were studied theoretically and experimentally. Analytical expressions are obtained for determining the uniformity of the course, the load of the bodies and the center of resistance of the plow, depending on its main parameters and the roughness of the relief of the cotton field. It is established that serial two-tier plows, due to the discrepancy between their width of the gripper and the width of the row spacing, do not meet the requirements of agricultural technology: the plowing depth is not stable, the coefficient of variation of the plowing depth reaches 16% for a trailed plow, and for a mounted plow - 25.8%; the transverse direction of the plough the bottom of the furrow turns out to be stepped; the value of the traction resistance changes at each pass of the plow. To improve the quality of plowing fields from under cotton, a new plowing method has been developed, carried out by a two-tier plow, the width of which is a multiple of the width of the row spacing of cotton. The width of the plow bodies is equal to half the width of the row spacing.

Parameters of slitter for embedding manure in soil for melon crops

“…Such a change in angles contributes to the rise of the formation and intensive soil loosening [18]. In this case, the angle of inclination of the ploughshare blade to the field side should be θ0=42º [20].…”

Pulling resistance of the front plow cornercutter

“…The main advantage of a disc cornercutter cutter is that it has a lower energy consumption than other cornercutter cutters. The disadvantage of the disc cornercutter cutter is that it mainly cuts the lateral surface of the blade during operation, has a complex design and consumes a lot of metal compared to traditional cornercutter cutters [37].…”

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.…”

“…In these studies, the issues of placing improved working bodies of a plow-ripper on its frame were not considered [11,19]. In this regard, the research work devoted to the substantiation of the scheme and parameters of a moldboardless plow-ripper with inclined racks of working bodies, which provide an increase in labor productivity and improve the quality of tillage, is appropriate in research and practical names.…”
