Итоги международной специализированной выставки АГРОСАЛОН 2016

    С 4 по 7 октября в Москве прошла международная выставка сельхозтехники АГРОСАЛОН 2016, которая в очередной раз подтвердила статус самого посещаемого, самого масштабного отраслевого события в России.

В МВЦ «Крокус Экспо» 543 компании из 32 стран представили свои передовые разработки и флагманские машины.

Уникальное мероприятие подготовлено совместными усилиями профессиональных объединений сельхозмашиностроителей России и Германии – Ассоциации «Росагромаш» и VDMA Landtechnik.

Выставка позволила 33 168 посетителям увидеть и оценить прогрессивные технические решения и новинки мирового сельхозмашиностроения от ведущих российских и зарубежных производителей. На АГРОСАЛОН приехали 136 делегаций со всей России, от Калининграда до Якутии. Такой интерес не случаен – АГРОСАЛОН дает гостям уникальную возможность лично провести переговоры с топ-менеджментом мировых лидеров сельхозмашиностроения. Особенно интересна выставка была профессионалам аграрной отрасли – сельхозтоваропроизводителям, ученым и машиностроителям.

27-я международная выставка «АгроКомплекс-2017»

    С 14 по 17 марта 2017 года в г. Уфа в ВК «ВДНХ-ЭКСПО» состоится 27-я международная выставка – «АгроКомплекс-2017», ставшая уже главным выставочным форумом Приволжья и Урала России.

Выставку организуют Правительство Республики Башкортостан Министерство сельского хозяйства Республики Башкортостан и Башкирская выставочная компания. Выставка проходит при поддержке Министерства сельского хозяйства Российской Федерации.

Сегодня, в контексте взятого страной курса на импортозамещение и развитие собственных аграрных рынков, выставка обретает особое значение. «АгроКомплекс» дает масштабную картину рынка новейшего оборудования, технологий, химии, удобрений и ветеринарных препаратов.

Ежегодно «АгроКомплекс» подтверждает свою роль главного делового Форума и основной площадки для диалога бизнеса и аграрной политики Приволжья, Урала и Сибири России.

За 4 дня дискуссий более 2000 представителей политики, бизнеса и смежных отраслей посетят деловые площадки Форума. В мероприятиях примут участие более 100 спикеров – экспертов отрасли из городов РФ, стран СНГ, Европы и Азии.

Noise in cab of a crawler agricultural tractor

Abstract
The working conditions of operator are considered as one of the most important indicators of technical level of a machine and its competitiveness in agricultural machinery market. The article presents the measuring data of noise level on operator workplace, based on the results of long-term tests of crawler agricultural tractors of 3 drawbar category for general purposes. Measurements of noise level in tractor cabs were carried out according to the requirements of state standards when performing the main type of works, namely the stubble tillage after harvesting of spiked cereals. Tractors produced by Volgograd tractor plant in 1993-2000 conformed to the sanitary regulations of tractors’ and agricultural machines’ technology and had the noise level about 78-80 dBA. Subsequent upgrading of crawler tractor’s cab led to worsening of work conditions in respect of noise. Noise level in cab of the Agromash-90TG 1040А tractor produced by Volgograd tractor plant in 2012-2015 reached 88-90 dBA. The analysis of the results of measurement of noise levels allows to make a conclusion that the main noise source in upgraded cab is the exhaust tube of engine. The construction of cab does not protect the operator against the noise of engine. Furthermore, the use of microclimate normalization system in cab of the Agromash-90TG tractor does not provide the reduction in air temperature to a comfortable level of 24-27 degrees C. Test results revealed that working conditions on the new tractor do not conform to the requirements of standards. Specialists of tractor industry organizing a new production of crawler agricultural tractors should take into account the previous experience of engineering developments in Volgograd tractor plant and results of state tests of tractors.

Experimental research of conditions of cylinder oil supply in high-speed four-stroke internal-combustion engine

Abstract
The research is relevant because oil supply processes in the cylinders of four-stroke piston engines with traditional cranking mechanism and combined lubricating system are understudied. The research aims to receive the experimental data on pattern of motor oil distribution by circumference of cylinder for the specified type of internal-combustion engine. The measurement method is based on organization of drainage and following quantity control of oil that is removed by piston rings from internal surface of the cylinder. Experimental device corresponding to this method represents the low-sized high-speed four-stroke air-cooled TMZ-450D diesel engine having a cylinder with six oil-catch through holes executed in its bottom support belt and supplied with thin-walled tubes. Tests were performed under rotation of crankshaft by means of outside source (balanced engine) with nominal speed. The oil filling of any first of six tubes was considered as a moment of ending for each experience. The quantity of oil in tubes was controlled by measuring of oil column length in every tube. During cranking both with air compression and without it, experiments show that quantity of motor oil removed by piston rings from non-loaded cylinder wall side in all cases is more by 15-18% than from the loaded one. Such pattern of oil distribution by circumference of a cylinder at which non-loaded side receives more oil than the loaded one, points to the infringement of principle of coordination between lubricating and loading conditions. That increases the risk of wear and bore scuffing in cylinder-piston unit. In spite of limitation by only one method and one object, the received results show the expediency of following studies of features of cylinder oil supply for the specified type of engines to increase their work reliability.

Unmanned mobile power unit for agricultural purposes

Abstract
It is shown that the basis of robotic technologies in plant cultivation is an unmanned mobile power unit for agricultural purposes on wheeled or tracked platform with hybrid power plant, motion control and machine vision equipment. Description of software algorithm and schematic circuit diagram of motion control are given. It is noted that machine vision is an integral part of working organs, because much of the information about the state of plants (growth rate, maturity degree, disease) is received through visual contact, as well as through systems of motion control and precise positioning. This information allows the robotic working organs to find the technological solutions and implement the required operations, and the unmanned mobile power unit to move on process route. Another fundamental function of unmanned mobile power unit is positioning and motion control on required trajectory. A brief analysis of implementation of this function by means of satellite navigation or ground facilities of positioning including machine vision and target indication is given. Satellite navigation systems provide positioning and identification on large areas, but do not work indoors. Network wireless system of local positioning allows to control the location and motion of objects and reliably identify them both outside and inside the premises. Combined application of such systems allows to extend the motion control of vehicles and agricultural machines to areas not directly visible for satellites: covered yards, buildings. That creates additional opportunities for control of local movements of products and personnel in industrial and non-industrial premises of closed and open type.
