INVESTIGATION OF ADVANCED MEANS TO REDUCE THE DAMAGE OF TUBERS WHILE POTATO MACHINE HARVESTING
DescriptionThe 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

LABORATORY-FIELD TESTS OF EXPERIMENTAL DIGGER WITH MODERNIZED DIGGING THE WORKING BODIES
DescriptionPotatoes in our country are one of the most cultivated cultures in agriculture. The most time-consuming process in the production of potatoes is harvesting. Currently for potato harvesting potato harvesters or diggers are used. Existing machines are not sufficiently well-behaved in adverse operating conditions such as the high and low humidity. Quality of work of the units and devices of potato harvesters depends on the digging working parts. In the process of potato harvesting up to 1000 tons of heaps from 1 hectare go through the units of the machine, which includes plant residues and dense soil out of row spacing. To eliminate or reduce the impact of this lack, on either side of the coulter we set cutting discs which prevent ingress of heaps out of row spacing. However, due to the imperfections of the design they are slipping during operation what causes accumulation and enhancing traction resistance. Based on these facts, the work on improving the digging working parts in the actual and future challenges for the country's agriculture

PROBLEMS AND PROSPECTS OF TRANSPORT TECHNOLOGY FOR VILLAGES
DescriptionModern condition agricultural transport (a significant part of it about 70%) is characterized by a strong deterioration of the rolling stock, the unsatisfactory state of the production base. More than 30% of vehicles operated outside the normative service life, the rest approaching to that state. In general, the provision of agrarian and industrial complex with agricultural vehicles is way below agrotechnical requirements. In the long term, farm machine engineering should focus on indicators of the technical level achieved by best samples of foreign agricultural machinery. Priority development is likely to receive the development of innovative technologies that provide a significant increase in productivity, efficiency and resource conservation in agriculture. To address the shortcomings of transport services agrarian and industrial complex we should improve transport technology with the use of transport logistics, expand and update the existing vehicle fleet, but due to the low solvency of agricultural companies and high prices for of automotive engineering, the problem of providing agricultural vehicles becomes most acute. Thus, the creation of new science-based solutions in technology and engineering for transportation farm produce in terms of Russia's AIC is the actual scientific and technical task that contributes significantly to the development of the country, as well as enhances the enjoyment of breakeven, competitive manufacturing

APPLIANCES, TECHNOLOGIES AND EQUIPMENT FOR HAULING OF FRUIT OUT THE GARDEN
DescriptionAn integral part of technological process for the cultivation of agricultural crop is the transportation issues. For their execution, we require significant energy and labor costs. The statistics show that the proportion of expenses for transportation of goods in agriculture reaches 25-40% of the total costs for ready-to-sale production, when the proportion of farm tractor transportations reaches 60% of the total. Thus, there are considerable losses of production, reaching in separate cases up to 50%. They are especially great in the harvesting and post-harvest cycles of crop production which is connected with crop damage during transportation. Large losses of fruit and vegetable products when transporting might be connected with their mechanical damage level during loading, unloading and transportation. This causes the urgency of the problem of preservation when transporting fruit and vegetables. One of the prior national issues is "... the development of directions to improve road transport maintenance with the aim of improving the quality of the transport process, which includes increasing commercial speed of freight flows by 2-3 times, increase productivity and profitability of road transport systems by 2-3 times, reducing the environmental load on nature by 20% ... " and others mentioned in the "Transport Strategy of Russia until 2020"

Description
Efficient dairy cattle breeding are largely dependent from technology content and service animals. Most farms use a tethered way content. With this method of milking, the technology requires the introduction of new techniques to increase productivity on the farm and cost reduction of dairy products. The most rational is improving the design of existing milking machines. Regarded device for automatic removal of hanging part of a milking machine, its structure and working principle. The main unit of the device is a pneumatic motor that operates from the vacuum system of the milking plant. In the housing mounted on the shaft of the pneumatic motor rotor with curved vanes, there are magnetic elements. These elements should have the necessary geometrical and force parameters to ensure the normal operation of the device for automatic removal of hanging part of milking machine. The article describes a laboratory research and an analysis of the magnetic elements. In laboratory studies, we have revealed a dependence of the traction capacity of pneumatic motor from linear and power parameters of the magnetic elements, as well as established necessary geometric parameters and the magnetic field strength of the elements for normal operation
