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

Description
The role of transport in agricultural production is significant. It is the connecting link in the technological chain of the agro-industrial complex (of the APC). On-farm transport in the APC together with cars and tractor transport are widely used. The rationality of the use of wheeled tractors for farm transport substantiates the possibility of their movement on asphalt and on dirt roads. The specific gravity of the tractor transport in the domestic agriculture is 22-27% of the total volume of transport and 50-60% of the volume of farm traffic. A high level of use of tractor transport has been observed in the countries of Western Europe and the USA. In the farms of leading countries of Western Europe (Germany, Italy, France, etc.) about 70- 90% on-farm transport of agricultural goods is done by tractor transport. Tractor transport in a live environment is running on roads with varying terrain, a wavy profile cover, on soils with different hardness and humidity. When driving vehicles at high speeds, the trailer is wobbling from side to side, constantly accompanying tractor transport during its operation. As a result, it is bad for propulsion, transmission, and it deteriorates the dynamic performance properties of equipment, working conditions of the operator. To reduce the amplitude of oscillations of the trailer, the operator is forced to work strenuously with the steering wheel or to slow down the speed, which in turn affects operator fatigue, as well as the performance and maneuverability of the vehicle. Thus, advanced technologies in electronics, sensor technology and software will determine the nature of agro-technical innovations and will lead to increased automation of business processes in crop production with the aim to organize the work more effectively, efficiently, accurately, environmentally friendly and economically feasible. When working with intelligent technologies, understanding the development of high-tech, precision engineering requires a revision to the personnel policy and education in agriculture, which should be based on the relevant organization of farms and their proper new type engineering solutions

ASSESSMENT OF COST EFFICIENCY OF USE OF DEVICES OF ULTRASONIC HANDLING OF FUEL
DescriptionOne of important features of development of modern society is special attention world the public to problems of rationality and efficiency of use of the existing energy resources, universal implementation of technologies of energy saving and search of renewable energy resources. Gradual depletion of world reserves of oil, increase in prices for traditional motor fuels, adverse ecological situation and other factors prove the relevance of more urgent use of the available resources and works promoting development of this direction. Deterioration in a global ecological environment requires adoption of more strict requirements imposed to the fuel used in an agro-industrial complex. According to the principle of cost accounting, each entity can rely only upon itself and consume only the resources it has. It is known that fuel costs constitute a considerable part in an expense structure of agricultural enterprises. In this case, the reduction in fuel consumption can be achieved through improved processes of fuel mixing and fuel processing (fuel dearomatization, ultrasonic treatment, magnetic, electrostatic and electromagnetic processing). Bench tests of a diesel engine equipped with an experimental device for ultrasonic treatment, showed good results, confirming the relevance of the use of such devices. Devices for processing are compact enough and consume little energy, while having a sufficiently high coefficient of performance. Having small size and relative simplicity of design that does not cause complex technical issues in production, these devices can be used on virtually any type of equipment that is used for the solution of agricultural problems. The purpose of this article is to evaluate the economy of the diesel fuel when ultrasonic treatment on the example of the motor transportation enterprise

RECYCLING OF TIRES AND THEIR ELEMENTS
DescriptionIn the world, recycling processes have recently become more common in order to save material and energy resources. Currently, in connection with the level of motorization, there grew a problem of recycling waste tires and their elements which is of great importance for many regions of the country. Decommissioning worn tires is a source of environmental pollution, bearing the prolonged character; they are not a subject to biological destruction and require constant increase of storage facilities. There is a continuous accumulation of used tires and we can recycle only about 20% of their amount. Worn tires represent very large-capacity products of polymer-containing waste, virtually resistant to natural degradation. Therefore, the problem of processing and secondary use, emerged from the operation of tires is of great economic and environmental significance. However, the worn tires are a source of valuable secondary raw materials: rubber, soot (essentially pure carbon), metal and synthetic cord. 90% of all waste of rubber are tires and represent a vast reserve of raw materials. In the emerging in the industry nonrenew- material resources the efficient use of secondary raw materials is of great importance. There are improved technologies for processing rubber goods, and the equipment used for it
