The Role of Technical Services in Management of Innovation Activities at Ukrainian Agricultural Enterprises
The ways of introducing innovations into production were found as a result of conducted research on innovative activity at agricultural enterprises in the Ukraine. By means of the developed schemes, the stages of selecting an innovative product were shown and the need to transform the decision-making system in agricultural production was justified. In order to improve the information flow system, it was found that the innovative activity of agricultural enterprises is influenced by the presence of innovation media and innovation-active staffing support of production. The low level of innovation activity of agricultural enterprises is due to the low level of scientific support of agricultura…
Justification of Construction Parameters of the Screen in the Small-Sized Household Biomass Chopper
The mechanism of influence of screen design parameters on the technological process and the particle size distribution of the chopped biomass were determined in this research. The presented engineering solutions make it possible to design the screen for chopping the given biomass material. The modernized construction expands the scope of application of small-sized chopper, especially when used in private farm households. Size control of the chopped material allows to use material as fuel, material for mulching of berry plantations and gardens, material for production of constructional and insulating wood concrete.
Modeling of Resonance Phenomena in Self-Oscillating System of Agricultural Machines
Factors affecting the interaction of the active cultivator paw with the soil environment are considered in this article. It was established that the active oscillating effect of tillage machines on the environment leads to reduction in its traction characteristics, and the design of symmetrical movable paw is capable of self-oscillation in a horizontal plane. It was developed the theoretical model of oscillatory movements that takes into account the main structural parameters of working bodies represented by symmetrical cultivator paws of the active type. For laboratory studies, a circular soil channel is used, which ensures the movement of the soil relative to the stationary working body f…
