THEORETICAL INVESTIGATIONS OF STRAW PARTICLES MOTION WHEN LEVELING HAY ROLLS
DescriptionOne can see some density irregularity within the roll in the baler with a chamber of constant volume. We have found out that the maximum density of hay roll width (the baler width) is observed in the middle part. This is due to the shape of the hay roll entering the baler. To even the hay rolls they have mounted some rotating disks having some inclined spring pins above the baler. To improve the roller distribution the disks above the baler have been pushed forward forming a tapering gap. The evening discs rotating above the moving roll will cause some relative motion of hay particles. The interaction of the evening disks with the hay roll in the vertical plane will be determined by the elasticity of the hay roll and the weight of the frame with the disks. We have studied the trajectories of hay particles motion with the help of MathCad program. We have had the following initial parameters: the degree of compaction (decrease of the roll height when evening), the friction coefficient, the angle rate of the evening disks, the number of pins and the speed of the hay roll. As a result we have got the trajectories of the hay particles motion when the evening disks functioning. The analysis of the trajectories has allowed to establish some basic parameters of the evening device such as the distance of 0.15…0.2 m between the pins; the degree of compression while evening 20...25 %, the angle rate of the evening discs 23...30 rad / s and the diameter of the evening disc 0.74 m. The application of the evening device in the form of the disks with pins provides a uniform distribution of hay particles edgewise of the baler ensuring preliminary hay roll seal press before passing to the baler pressure chamber that contributes to getting the rolls with larger mass and a uniform distribution of hay density inside the roll

REDUCING ENERGY CONSUMPTION IN AGRICULTURAL PRODUCTION (POTATO EXAMPLE)
DescriptionIn recent years, in many countries around the world, much attention is paid to the issues of ensuring of rational use of energy resources, due to a number of objective factors, chief among which are: the lack of own energy resources to meet domestic energy needs; the sharp increase in the cost of production and the production of energy resources; further growth in energy needs; the presence of large potential opportunities to reduce unproductive losses of fuel and energy. In the world, the challenge now is to ensure a gradual but steady transfer of the economy on energy saving way of development. To achieve the goal of reducing energy costs we might use two ways: firstly, the widespread introduction of energy saving technologies, and secondly, the reduction of material production, improving its quality and service. In agriculture, the improvement of the technological process can be carried out using new tillage methods, improving the organization of production and tools. Further development of mechanization in agriculture will contribute to further growth of electrification in the agricultural sector, which will significantly reduce the use of the most expensive and limited energy resources. The article offers a technique of the estimation of the efficiency of consumption of energy in agricultural production. In order to compare the efficiency of machines in the cultivation and harvesting of potatoes, there was conducted an energy assessment of the operations of modern technology. As variables, there were investigated different operation modes of the machine: working speed and working width, depth of stroke of the working bodies. In the process of evaluating energy operations, modern technology to prepare the soil for planting potatoes was determined humidity, mechanical composition and soil type. As a main factor in the analysis of technological methods, we have taken the overall specific energy consumption and specific energy consumption for the digging below tuber formation. Analysis of theoretical researches of agricultural machinery has led to the conclusion that the energy cost of implementing the technological process in the machines of different designs varies

THE METHOD FOR CONTROLLING POTATO TUBERS HIDDEN DAMAGES
DescriptionWhile mechanical harvesting of potatoes, about 20-40% of the tubers get damages. Dynamic loads, injuries of the tubers, causing internal damage – which is browning of the flesh of the tuber, which occurs in the process of its storage. At the same time, ways to express control of damage to potato tubers will allow both reducing damage during harvest, and promptly sending damaged potatoes for recycling before the results of mechanical stress for the tubers during harvesting. The definition of internal damage to the potatoes is possible because of the analysis of the different elasticity of the tissues of damaged and undamaged tubers. The value of overpressure of the device is chosen such way that during deformation of tubers there mainly has been compression of the damaged tissues of the tuber, with the least turgor. The degree of damage of samples of tubers is determined by the ratio of the volume of damaged tissues of tubers to the total volume of the sample. We have given the mechanical properties of tissues of tubers, fruits and root vegetables, their structure, dimensional characteristics, it can be assumed that the use of this method of determining internal damage possible for apples, carrots, beets and harvest of other crops. Use of damage control will enable timely identification of hidden damage and make it possible to eliminate their causes, which lead to increase loss products
