MODERNIZATION OF ZIL-5301 FOR USE IN AGRICULTURE
DescriptionThe role of transport in agricultural production is considerable. It is a connecting link in a single technological chain of agroindustrial complex of the country. The successful production activity of agricultural enterprises depends largely on the proper use of available forces and means. One of such means is machine-tractor fleet relating to technical basis of agricultural production. Its functioning is reflected in the whole cycle of production, from planting and ending with cleaning. Therefore, the use of the machine and tractor must ensure receipt of the highest possible efficiency at the lowest cost, as production cost agricultural production includes in its membership the costs of mechanized and transport works, which should be kept to a minimum. In this regard, transport processes should be carried out the most rational means. Rational application of those or other vehicles is based on ratios of basic load ratings, adaptability to the changing road conditions, terrain, improving functionality, improved adaptation to technical operation in the conditions of agricultural production. When choosing a vehicle, special attention must be paid to the size of the economy, the direction of its activities, the structure of commodity products, and the degree of its centralization. For successful economic activities of the agricultural enterprise it requires a different carrying capacity and terrain vehicles. At present, the majority of the automobile park of agricultural enterprises is cars and trains of general purpose, which have large load capacity and low permeability. In the agricultural enterprises of the Ryazan region today there are about 4.5 thousand commercial vehicles, mostly models of GAZ, KAMAZ and ZIL. The issue of reducing the cost of transport operation should be individualized for each sector because of its distinctive features (activity, volume of traffic, the structure of commodity production, the state of farm roads, etc.)

SOME ASPECTS OF REDUCING FRUIT DAMAGE DURING HARVESTING AND TRANSPORT OPERATIONS
DescriptionFruit harvesting is the final and decisive operation in the general work plan for growing fruit, which largely determines the qualitative and quantitative indicators of production and economy of industry in general. Increasing productivity by improving the safety of fruits and vegetables is a priority and not an easy task. For example, the use of cleaning technologies with the use of machinery for harvesting of apples by shaking can significantly reduce the time of gathering fruit compared to hand harvesting. This technology may be applicable, if the fruit is grown for the manufacture of juices, jams, etc. Currently, in several European countries and in the USA, they widely use fruit harvesting platforms and machines. The leader in the production of fruit harvesting platforms is Italy. To reduce the damage to fruit in agriculture, the analysis of the traumatic factors is of great importance, with the analysis of available machines and their subsequent modernization with the aim of improving the reliability and quality of harvesting and transport process, taking into account of the algorithm for solving these problems, the creation of new varieties of fruits and vegetables suitable for machine processing, strict compliance with deadlines and agronomic requirements for the performed technological operations, taking into account the savings of energy and resources when using mobile technology. In addition to the modernization of the machines for efficient operation, it is necessary to improve also the scheme of planting of gardens and methods of cultivation, transfer horticulture to intensive way of development

NEW TECHNICAL SOLUTIONS FOR A SEPARATION OF THE ORGANS OF POTATO MACHINERY
DescriptionOne of the promising directions of development of agriculture of the Russian Federation is to increase the production, improve the quality and decrease the cost of potato cultivation. Annual cleaning is one of the most intense and costly in transport and technological processes. Potatoes - blending high culture and very picky about cleaning. The highest yields and income from potato production get where embedded technology to optimize energy and labor costs. The main (though not only) the special technical means used during machine harvesting potatoes, are potato harvesters. The main problem when cleaning is a problem of balancing conflicting requirements to the process and possibilities of agricultural machinery. Including increasing the purity of the tubers in the container with one hand, minimization of losses and damages of tubers on the other hand, when the performance of equipment. In this article we propose a circuit-design solution separating the working body of the potato harvester that allow for cleaning to significantly reduce the amount of traumatized potatoes in the process of separating soil and vegetable impurities, creating the preconditions for the elimination of damage to the tubers on the hard side of the working bodies of harvesting machines. Informed choice and timely use of plug-in modules (separating working bodies) in modern potato harvesting machines at work in specific climatic conditions allows them to fully match the list of regulated agronomic requirements. Thus, the creation of new science-based technical solutions for a separation of the organs of potato harvesters is an actual scientific-technical task, which makes a significant contribution to the development of the country

Description
The transportation process plays an important role in the delivery of agricultural products to the consumer. On how well the fruits are preserved, their grade will depend, and, consequently, the price of them. It is known, that the annual damage from losses of agricultural products in the agro-industrial complex amounts to 8 billion rubles, according to various estimates. A large number of different factors affect the safety of fruits during transportation: temperature, humidity, smoothness of the vehicle, type of container, etc. The more factors will have a negative impact on fruit and vegetable products, the more losses will ultimately be. The appearance of dents and abrasions on the fruits gives rise to the formation of foci of rot, leading to damage to the transported products, and, as a consequence, reducing the grade. In order to reduce the losses of fruit and vegetable products in the process of transportation, the USSR and the Russian Federation have been and are working on the creation of containers and ways of transporting pomegranates. All of them, according to the authors, are able to reduce the dynamic loads that arise during the transportation process and have a negative impact on the transported products. However, due to various circumstances in commercial gardening all these developments have not been extended

JUSTIFICATION OF THE RIGIDITY OF COMPOSITE BARS OF A POTATO HARVESTER ELEVATOR
05.20.01 Technologies and means of mechanization of agriculture (technical sciences)
DescriptionHigh-strength steels are used to increase the reliability of potato harvesters. With the advent of new materials and new technologies in agricultural engineering, it is possible to significantly reduce the mass of working bodies, to reduce energy costs. The elastic system of the composite elevator bar, unbalanced by the impact of the component of the potato heap, is in oscillatory motion. An increase in the height of the fall, and hence the speed of collision with the bar of the component of the potato heap, determines the amount of deflection of the composite bar. During vibrations, in addition to static deformations, dynamic ones are added, depending on the magnitude of the impact force. It was established that a bar made of composite material should have the following parameters: elastic modulus E = 55000 MPa; the diameter of the composite bar d = 0,012 m
