INVESTIGATION OF ADVANCED MEANS TO REDUCE THE DAMAGE OF TUBERS WHILE POTATO MACHINE HARVESTING
Description
The most labor- and energy-intensive part of potato machine production technology is harvesting which is done mainly with harvesters. Modern potato harvesters meet the required efficiency data in favorable conditions. In erroneous conditions (primarily characterized by high or low soil moisture) the efficiency of separating the tubers from impurities is reduced, and the loss and damage of the products increase. This situation is due to the imperfection of the separation device of potato harvesters. Up to 1000 tons of soil per 1 ha is separated at the separation device in the process of harvesting. As a result, the potato harvesters capacity on the whole is determined by their separators output. Nowadays, rod elevators are most widespread and used. One of the main drawbacks is the significant increase of tubers damage in a case of low soil moisture mainly caused by the contact of the tubers pile with the side frames of the harvesting machine. From the above reasoning, one can confirm that the increase of capacity and functioning quality of potato harvesters’ separation devices is an urgent scientific-and-technical task of agriculture

Description
The effectiveness of disinfection depends on used disinfecting materials for vans, their actions and technological parameters of the installation for applying disinfectants. Hot mist generators provide uniform distribution of particles of disinfectant solution inside the van for transportation of agricultural products. The parameters of the generator of hot mist affecting the quality of disinfection were investigated. Tests were conducted for the vans used to transport agricultural products. For studies we used the vans in operation, which transport farm animals (pigs) and had been disinfected before. Sampling for the research on contamination was performed with pre-prepared swabs. Factorial experiment was planned with using scheme #32, and as a result of significant factors in the univariate experiments we set a temperature of the aerosol disinfectant solution and the duration of surface treatment. As an optimization function we have chosen disinfection efficiency of bodies of vehicles carrying agricultural products. Comparing the results of the experiments on different groups of microorganisms we have found that the optimal mode of hot mist generator with a dispersing device are: the processing time of 1 m2 - 8.5 at the processing temperature - 65º C

Description
Based on the previous investigations we have underlined the need to increase fruit and vegetables preservation quality while transporting them from the producer to the consumer at the expense of improving the road transport operation for its intended purpose. We have made a conclusion about the need to develop strategies for maintenance and repair as for the actual technical state at the expense of developing the diagnosis system based on the development of a math model of changing the technical state of the diagnosis object, developing a method of rational set of objects to be diagnosed and determining the technical state optimal control frequency. We have confirmed that the above mentioned is possible when considering the system of technical operation of road transport as an organization-production system and applying the engineering-cybernetic approach to improve this system. We have considered the basic requirements for the efficiency indexes when investigating and improving the operation system that will allow achieving the aim we have had and can be described mathematically. We have made a conclusion about the urgency of the issue we studied and the possibility to develop the efficient operation system of road transport based on the provided criteria

THE METHOD FOR CONTROLLING POTATO TUBERS HIDDEN DAMAGES
Description
While 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

THEORETICAL INVESTIGATIONS OF STRAW PARTICLES MOTION WHEN LEVELING HAY ROLLS
Description
One 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
