Study on machine for processing and preparing the soil for sowing potatoes on ridges

Abstract

The technologies used to prepare the soil for sowing potatoes on ridges, consisting of numerous soil preparation operations, lead to loss of moisture, prolonging the sowing period and increasing operating costs. The aim of the research is to develop a machine for processing and preparing the soil for sowing potatoes on ridges. The authors have developed a technology for preparing fields for sowing potatoes on ridges and a machine for its implementation. The basic principles and methods of classical mechanics, mathematical analysis and statistics were used in this study. On the basis of multifactorial experiments, the following parameters are justified: the angle of inclination of the ploughshare blade in the range of 6-70, the height and length of the guiding knife in the range of 94-110 mm and 107.2-136 mm, respectively. The main parameters of the working bodies of the machine and its technical characteristics are given. The results of the tests have established that the proposed machine for preparing the soil for sowing on the ridges reliably performs the specified technological process and its performance indicators fully meet the requirements. The use of the machine provides a reduction in operating costs for processing 1 hectare of area in comparison with the technical means used by 33.8 %.

Ridge forming machine for sowing cereals on sloping fields

“…Based on the analysis of the conducted research work, the use of slope field processing and grain sowing technologies and technical tools in developed countries, as well as the requirements of agrotechnical for grain planting, a combined machine for processing and sowing grain on sloped Fields was developed [3,4,7].…”

“…Analysis of research has shown that prevention of water erosion during seeding of grain crops on sloping fields and conservation of moisture in the soil, as well as reduction of fuel, labor, and material costs, can be achieved by applying technologies of soil treatment with simultaneous seeding of grain seeds and formation of anti-water erosion ridges and machines for its implementation [3][4].…”

Parameters of the soil-holding part of the slurry spreader

“…Uzbekistan is one of the leading countries in the world in the production of melon products and especially valuable varieties of melons, which are famous for their taste qualities not only in our country but also far beyond its borders [1][2][3][4]. Therefore, it is necessary to increase the production volume of melons.…”

Parameters of slitter for embedding manure in soil for melon crops

“…There is a lot of data in the literature regarding the fact that it is most rational to apply organic fertilizers for melon crops locally, which accelerates the formation of the root system, reduces the negative effect of the diversity of natural soil fertility, promotes the alignment of plant development, simultaneous and earlier fruit ripening, increases by 10-30% yield, by 1.0-1.5% sugar content in fruits and others [1][2]. However, this method is practically not used in production due to the lack of tools for the local application of organic fertilizers for melon crops.…”

“…To do this, it is necessary that when the soil interacts with the elements of the slitter, its vertical movement prevails. The well-known works, D. Chuyanov [1][2], F. Mamatov , B. Mirzaev [4-7, 12-19, 21, 23, 26], K. Ravshanov [9,22,25,28,33], U. Kodirov [1,21,28,33], I. Temirov [9,11,33], on substantiating the parameters of plow hulls, are mainly aimed at studying the process of lifting and complete rotation of the formation, in which horizontal soil movement prevails. Studies of moving the soil along the oblique blade have been carried out.…”
