Solution of problems of potatoes and stones pneumatic separation and bed stone separation during potatoes planting. In framework of the proper work in this thesis were obtained the following information" Pneumatic separation problems, problems of bed soil separation before potatoes planting, concrete conclusion for realisation in practice.Available from STL Prague, CZ / NTK - National Technical LibrarySIGLECZCzech Republi
Analyza faktoru ovlivnujici vykonnost stroju na hnojeni, zpracovani pudy a seti.
Machines are being equipped by monitors and controlling units able to receive the GPS data. They record a real time, speed vector and selected data about machine work for geographical coordinates (material flow, working, resistance, diesel fuel consumption e.t.c.) These data can be used for evaluation of the field efficiency, working speed and idle time within individual plots. The skilled operator can analyse machine operations during work shift at graphical display of machine trajectory (GIS-geographical information system). The GIS tools enable also to classify technical and productive conditions of the plots (communication access, size and shape). Just evaluation of the machines exploitation parameters in relationship to these operative factors is a qualitative contribution of that method compared with classical time photographs. At the records evaluation of machine aggregates work soil tillage and fertilization the effect ov operational factors onto operative efficiency reached on individual plots was proved. The theoretical efficiency given by the machine exploitation characteristics decreases due to larger share of non-productive travels within smaller and irregular plots. There is a correlation between average working speed or traveled unit way within plots and defined classes of size, length and plot shape. From that correlation results knowledge of operative efficiency dependence upon plots operative properties which enable to make more accurate the machines planned exploitation.Available from STL Prague, CZ / NTK - National Technical LibrarySIGLECZCzech Republi
Technologicke systemy pro poskliznovou upravu a skladovani zrnin
The report presents a basic requirements for corn crops storage, summarized information principal technological knots of storage and past-harvest lines at the prior-producers with storage capacities created in tower a hall storing spaces. There were evaluated chosen storage sites of capacities created in hoppers "LIPP and VITKOVICE", and other tower containers of unit storage capacity 50t - 70t and above 100 tons. There also were evaluated the hall storage sites. In the tables are presented dta about total storage capacities, their age and age of their last reconstruction, storage equipment and possibilities to the corn past-harvest processingAvailable from STL Prague, CZ / NTK - National Technical LibrarySIGLECZCzech Republi
Objektivizace normativu spotreby pohonnych hmot a energie na vyrobu zemedelskych produktu a tvorba jejich databaze
Collection and analysis of current normatives and known values of fuels of fuels and energy specific consumption in working processes of production of plant and animal products. Working-up of detailed methodics for total time of solutin determining products related to the normative s finding out.

Vyzkum aktualnich problemu technologii vyroby krmnych smesi
The report is articulated into theoretical and laboratory parts and into investigation in agricultural practice. In the first theoretical part is dealt with comparison of storage and cylinder method of corn crops processing from point of view of specific energy consumption and creation of acquired product structure as well as width of crushing gap and performance for various types of corn crops. The report also evaluates the moisture effect onto energetical balance of crushing and milling and the feeding mixtures dispersity according. To the law No 91/1996 concerning feedshuffs. The second part present results of operative investigation of suggested and realised line for production of feeding mixtures of output 3 t.h-1 in agricultural enterprise. The part also presents verification of newly developed technological knot, i.e. sectional equalizing bin for macrocomponents enabling continual operations of the crusher and milling divide for feedshuffs. This method proved its high effectiveness and contrilented significantly to the better performance of whole technological line. The report also presents the economical assessment of the line. In the third part are presented results of investigation of the maize storage of higher harvest moisture up to 35% in protective atmosphere of CO_2 in tower silos. The feeding corn crops in CO_2 atmosphere storage maintains the corn quality within all time of storage, the CO_2 concentration is changing phighty. Within 11 month there was formed out this CO_2 in range 75-805. The unfavourable moulds and bacteria development has not been proved, the corn fermentation process was realized to the 10 th day after the tower silos closureAvailable from STL Prague, CZ / NTK - National Technical LibrarySIGLECZCzech Republi
