APPLICATION OF ENERGY AND RESOURCE ENGINEERING SOFTWARE IN COTTON FIELDS
Annotation. This article is devoted to the mechanization of agriculture and is aimed at achieving resource savings through the effective use of machinery and technology in lightening the burden on farmers in field farming.
Keywords: Flexible, technical device, technology, aggregate, softening fingers.
Research work is being carried out around the world to develop new scientific and technical bases of resource-saving technologies and technical means for softening the crust in the fields planted with agricultural crops. One of the important tasks in this direction is the development of a constructive scheme of working bodies and substantiation of technological processes, quality of work and development of resource-saving working bodies in the process of interaction with the soil. At the same time, it is necessary for the cotton cultivator to develop disk working bodies that soften the layer at the required level without damaging the cotton seedlings. Extensive measures are being taken in the agricultural production of the Republic to save resources, cultivate agricultural crops on the basis of advanced technologies and develop high-efficiency agricultural machinery [1,2]. The Action Strategy for the further development of the Republic of Uzbekistan for 2017-2021 includes, among other things, "Modernization and accelerated development of agriculture, further improvement of the reclamation of irrigated lands, development of reclamation and irrigation networks, intensive methods of agricultural production, especially water and resources. introduction of modern saving agro-technologies, use of high-yielding agricultural machinery ". One of the important tasks in the implementation of these tasks, including the maintenance of agricultural crops and the technical and technological modernization of post-precipitation mitigation equipment [3].
Irrigated lands in cotton-growing areas are focused on natural-climatic and soil conditions, mechanical composition of soil, tillage technology, machine types and agro-technical requirements. In the early development of agricultural crops should be provided with soil, air, heat environment for the growth of young seedlings. The onset of spring rains prevents the young seedlings from growing, developing, and sprouting, that is, the rain turns the soil into a muddy layer and prevents the sprouting seedlings from developing by squeezing the roots. Our
farmers try to create a comfortable environment by mowing the lawn, but it takes a lot of time and physical effort. Mechanized complex cultivation, on the other hand, takes a long time and prevents the fine compaction of the resulting hard soil, as well as the formation of lumps .
The proposed utility model applies to the field of agricultural mechanization, in particular the process of primary processing between rows. The structure of the new device will consist of the following. A metal profile with a total length of 3.5 meters (1), 4 handles (2) are welded, one (3) working body is mounted on each handle. This means that when each working body processes cotton seedlings sprouted from one row, it is possible to further increase the number of rows with a total processing capacity of up to 5 rows. We determine the width of the unit depending on the power of the tractor. Tractors with 80-100 horsepower can handle up to 8 rows. The main part of the working body is mounted on small frames prepared by welding (4) with soil softening fingers (5). The softening fingers are attached to the small frame by means of rotating hinges or bearings. From the forward motion of the traction tractor, the softening fingers rotate and rub the fold (picture 1).

As for the technology of operation of the unit, the device aggregated on the tractor TTZ-80 is adjusted for processing the grids by means of adjustable traction. It is necessary to ensure that the working body is parallel to the grid and lies flat on the ground, otherwise the quality of the processed field will not be good.
Picture 2. The appearance of the working bodies of the hardening device in
the process of work.
It should be noted that the range of 0.18-0.48% damage to cotton seedlings meets the initial requirements . Therefore, on the basis of the above data, it can be said that the diameter of the toes should be in the range of200-250 mm for quality softening of the layer at the required level with minimal damage to cotton seedlings. (picture 2)
By using this device, the quality of work can be improved by reducing the consumption of metal, energy and fuel consumed in the process of softening the coating.
