Надійшла 2.06.2020 Мета. Оцінити технічну реалізацію і виробничу ефективність мостових засобів механізації для колійної системи землеробства в технологічних процесах обробітку ґрунту та внесення технологічних матеріалів на прикладі агрозасобу з розробленою нами конструкцією. Методи. Експериментальні дослідження проводили як за загальноприйнятими, так і за розробленими методиками з використанням сучасного тензометричного і контрольно-вимірювального обладнання з аналогово-цифровим перетворенням сигналів від датчиків інформації. Результати. За результатами експериментальних досліджень мостового агрозасобу у складі сільськогосподарських знарядь для поверхневого обробітку ґрунту доведена висока пристосованість до виконання технологічних процесів з обробітку ґрунту. Побудовано порівняльні графіки нормованих кореляційних функцій і нормованих спектральних щільностей профілів нерівностей слідів постійної технологічної колії і профілів нерівностей агрофонів після проходу зубової борони, S-подібного пружинного розпушувача, а також ротаційної борони.

In terms of the future development of the mechanization and automation of the agricultural production, the transition from the narrow-gauge towing tractor to the wide-span (gantry) traction and power unit, also called the agricultural gantry system, seems to be a promising trend. For the purpose of combining implements with the agricultural gantry system with the use of a manifold power take-off system, it is necessary to undertake theoretical research into such power units with regard to their suitability for their functional purpose. The aim of the investigations was to analyze the laws governing the effect that the parameters and operation conditions of agricultural gantry systems have on their power balances and at the same time to outline the principal trends for the development of the theory of such machines with that aim in view. As a result of the investigations, it has been established that the power intensity rate of such agricultural gantry systems travelling at working speeds within a range of 10 km•h -1 is equal to 23.5 kW•t -1 . Also, the agricultural gantry system is capable of producing a traction force of 6.37 kN•t -1 of its operating mass provided that a sufficient grip of its undercarriage on the surface of the permanent process track is ensured.

“…Sustainable highly efficient development of track and bridge agriculture [1][2][3][4][5][6] in the world is possible provided the widespread implementation of scientific and technological progress. At the same time, the problem of finding new tillage implements, machines and tools for their effective use in track and bridge systems of agriculture becomes extremely relevant [7,8].…”

Goal. To assess the technical implementation and production efficiency of bridge mechanization for the track system of agriculture in the technological processes of tillage and application of technological materials (on the example of an agricultural tool with a developed design). Methods. Experimental studies were performed according to both conventional and developed methods using a modern strain gauge and control measuring equipment with the analog-to-digital conversion of signals from information sensors. Results. According to the results of experimental studies of the bridge agricultural unit as a part of agricultural tools for surface tillage, high adaptability to the implementation of technological processes for tillage has been proved. Comparative graphs are built of normalized correlation functions and normalized spectral densities of profiles of irregularities of traces of a constant technological track and profiles of irregularities of agrophones after the passage of a toothed harrow, as well as a S-shaped spring ripper, and also a rotary harrow. Based on them, it is established that the work of agricultural tools for surface tillage has a good effect on the nature of the non-uniformity of oscillations of their traction resistance. Conclusions. The main generator of the formation of irregularities of the longitudinal profile of the soil traces of the constant technological track is the parameters of the soil hooks of the tires of the wheels of the bridge agricultural unit. The oscillations of the irregularities of the profiles of the treated agrophones by the bridge agricultural unit with attached agricultural tools (S-shaped spring ripper and rotary harrow) are smoother as a result of the movement of the agricultural unit along the compacted traces of a constant technological track. The quality of tillage with units based on bridge agricultural unit is approximately the same as in similar traditional machine-tractor units. But the specific energy consumption per 1 ha of the cultivated area with new units is lower by 40%.
