The machine for the preparation of the soil in sowing of plow crops under film

Abstract

In the world much attention is paid to the development and application of machines that perform all technological processes of soil cultivation and preparation of soil for sowing crops in one pass on the field. The aim of the research is to substantiate the constructive scheme and mutual arrangement of the working elements of the machine for preparing the soil for sowing melon crops under the tunnel-type film. The authors proposed new technology for preparing the soil for sowing melon crops under the film of the tunnel type in one pass of the machine, including the surface loosening of the covered soil, milling-free loosening and formation of irrigation furrow along the axis of symmetry of the sowing zone, preparing the strip of soil for sowing melon crops under the film of the tunnel type. The design of the developed combined machine for the realization of the offered technology is resulted. The basic principles and methods of classical mechanics, mathematical analysis, and statistics were used in this study. It is established that the most optimal design scheme of the machine is considered to be a scheme with a sequential installation of a lancet leg, pairs of deep loosening machines, furrow cutters, and rotary working elements inclined to each other. It is theoretically proved that qualitative preparation of the field for sowing melons with minimum energy consumption is provided with the longitudinal distance between the deep loosened and the lancet leg of 40 cm, the transverse distance between the deep loosened and the support wheel of 10 cm, the longitudinal distance between the deep loosened and the furrow cutter of 50,6 cm, the longitudinal distance between the furrow cutter and the rotary working device of 123 cm.

Traction resistance of a ripper with a current distribution line

“…Inside each branch pipe, movable reflective plates 6 and 7 are installed, which cut the fertilizers moving along the tool-conducting channel into parts, followed by their direction to the corresponding soil horizon. The reflective plates of the conductive channel do not completely block it, so some of the fertilizers enter the lower distributor of 8 [25][26][27].…”

“…Also, one of the important tasks in agriculture is the development of technical means for the formation of ridges with the simultaneous introduction of mineral fertilizers in the zone of development of the root system of plants [8,24]. In agricultural production, special attention is paid to reducing labor and energy costs, saving resources based on advanced technologies, and developing high-performance agricultural machines [8,[24][25][26].…”

“…The development of new tillage technologies and the improvement of machinery to prepare crops, including gourds, is an urgent task in agriculture . The problems of developing improved tillage technologies and tillage machines are considered in many scientific papers [24][25][26][27]. Research on the development of tillage machines and machines for preparing soil for sowing crops, including gourds, and the study of the interaction of working bodies with soil were carried out by F.Mamatov , B.Mirzaev [4][5][6][7][8][9][10][11][12], [14][15][16][17][18][19][20][21], [28][29], U.Umurzakov [4,19], N.Aldoshin [3], [10][11], I.Ismoilov [3], [10][11], D.Chuyanov [5,27], U.Kodirov [6,24], H.Ravshanov [4][5], [6,20], [25][26], I.Ergashev [2,6,12,23,30], P.Berdimuratov…”
