05.20.01 Technologies and means of mechanization of agriculture (technical sciences)
DescriptionThe article presents results of theoretical and experimental studies on the justification and experimental confirmation of the influence of hydraulic seeding process modes on the parameters of row seeding technology for seedling crops. It is hypothesized that it is possible to ensure a uniform depth of seeding within 0.5...1.5 mm by feeding seeds into the soil by hydraulic means using a liquid. We have compiled a nomogram of the influence of the height of the initial level of the liquid and its density on the amount of pressure exerted by it on the soil. It was found that the pressure of the polydisperse system on the soil increases with both the density of the liquid and the height of the initial liquid level. Experimental studies have been conducted to study the effect of the pressure exerted by the liquid on the soil and the speed of the drill on the depth of furrow formation and the depth of wetting the soil. The article determines empirical dependences of furrow depth on the pressure exerted on it for different types of soils. It is found that the depth of soil wetting decreases with increasing speed of the drill

TEMPERATURE REGIME OF THE TREATED SOIL LAYER
DescriptionThe article discusses the influence on the thermal regime of soil by agricultural activities, as well as the results of studies on determination of temperature in different soil layers under conditions of insufficient and unstable moistening of southern Russia. Experiments were performed in the experimental field in FSRI of the «ASC «Donskoy» (Zernograd, Rostov oblast) in terms of long-term stationary experience in the cultivation of soybeans with different technologies (traditional, zero). We performed the soil temperature checking at a depth of 30 and 60 cm using the temperature sensors with a measurement range from -40S to + 85S with a measuring accuracy of ±0,6S. For accumulation of data were used in the logger (weather station) Watch Dog 1400 series Micro. The purpose of the research was to determine and compare the influence of technologies of processing of soil on the temperature of the soil at different levels. On the basis of the conducted researches it is established that the average value of the ambient temperature stood at 23,8S a standard deviation of 3,1S. These figures are higher than the temperature of the soil at the background processed by traditional technology, and the raw background. The lowest average soil temperature at a depth of 30 cm (21,2S) recorded at zero background, obviously due to the presence on the soil surface of plant residues that protect the soil from solar radiation. Thus, the soil as a dynamic system converts the input signal (the ambient temperature) so that it is reduced in size and the rate of change (dynamic). These soil characteristics are determined by the technologies of soil processing

CURRENT STATE OF MECHANIZATION OF TOBACCO HARVESTING
DescriptionThe article presents results of studies of the present state of mechanization of tobacco harvesting. The aim of the research was to assess the state of the technical equipment of the tobacco farms in the current economic conditions. We have performed an analysis of the technologies of harvesting tobacco. Main problems of harvesting tobacco leaves were shown. We have analyzed the main constructive scheme of tobacco harvesters used for different technologies of harvesting tobacco leaves. The article gives main advantages and disadvantages of the applied technical solutions and lists tobacco harvesters used in foreign tobacco farms. A disadvantage was the impossibility of adaptation to the domestic types of tobacco. In the end, we have developed a project for solving scientific and technical problems of complex mechanization of technological processes of preparation of plantations to drying process, carrying out machine harvesting and preparing tobacco leaves harvested by the machine. This involves three stages. This will solve the problem of insufficient technical equipment of production of raw tobacco

RESISTANCE OF THE SOIL UNDER THE INFLUENCE OF HORIZONTAL DISK WORKING BODY
DescriptionTillage plays an important role in the production of cereal and grains. The issues of improving the methods applied for soil treatment aimed at improving its quality significantly influencing crop yield have been considered. Reducing of all types of costs: energy, labor, money was also taken into consideration. In this article, based on numerous studies we have proposed to use the effect of oscillatory motion in the working body of tillage, improving the design of tillage machines, reducing the metal consumption of the machine, the intensity of the process while increasing quality of work. The article reveals issues related to embedding of the new tillage of the working body running in a horizontal plane and having special tabs (blade), allowing it to make a reciprocating rotational motion. This working body provides the undercutting of a soil layer and root system of weeds, the crumbling of the soil layer and its interaction with the working surfaces of the blades. The conditions of the sliding soil layer on the surface of the working body and reducing the pressure of the reservoir to the working body are proposed. It decreases the compression of the reservoir and the tractive resistance. We have substantiated the conditions for reciprocating rotational motion of the proposed disk of the working body in the working plane close to the horizontal, when interacting with a layer of the soil

RESOURCE CONSERVATION IN THE PRODUCTION OF SPRING BARLEY
DescriptionThe article discusses the possibilities and presents the results of research on the cultivation of spring barley with different production technologies in conditions of insufficient and unstable wetting of the south of Russia. Experimental studies were carried out in a stationary experiment with a four-field crop rotation with different variants of tillage (dump, flat-cut, layered, without tillage – no-till). It is established that the most expensive is the waste treatment of the soil (PN-5-35), and the least expensive is the technology excluding the impact on the soil. At the same time, the operating costs of labor and fuel consumption at no-till are lower, respectively, by 82-107, 23-48, 131-188% in comparison with traditional types of technology. Hectare fuel consumption with zero technology is 131-188% less than with traditional technologies and amounted to 22.8 kg / ha. The cost of production of spring barley using no-till is 8-41% lower compared to flat-cut, layer-by-layer, and dump technology and amounts to 285 rubles per cent. Calculated per 1 hectare, labor costs, fuel consumption, wages, fuel costs, deductions for renovation and repairs, as well as total operating costs for traditional basic tillage technologies increase, respectively, 1,23-1,48; 2,31-2,88; 1,30-1,56; 3,1-3,81; 1,65-1,85; 1,81-1,96; 1,83-2,09 times compared with no-till. The use of spring barley cultivation technology that excludes impact on the soil provides a fairly high efficiency even at lower yields

PRINCIPLE OF DIFFERENTIAL THRESHING DEVICE OPERATION
05.20.00 Processes and machines of agroengineering systems
DescriptionPlanetary mechanisms are used to create the working movement of the Executive bodies of metallurgical and mining machines. Roller working bodies, for the drive of which planetary mechanisms are used, are increasingly being used in the designs of harvesting machines. The processes occurring in the differential threshing devices of harvesting machines are poorly understood, due to the lack of information about the properties of the material in the event of rapidly changing stresses in them. This work is the result of the analysis of previous theoretical as well as experimental studies in the field of threshing. We describe the technological scheme of the shock-vibration threshing device and the principle of its operation. The possible variants of arrangement of drum rolls and drumming are considered. The relationship between the angular velocities of the drum, the drum rolls and the sub-drum is elucidated. Installation of three-sided rollers on the threshing device according to the scheme proposed by us allows additional shaking of the whole threshed rice mass from 75 to 110 times per second
