ANALYSIS AND DESIGN PARAMETERS FOR INCLINED ROTORS USED FOR MANURE DISPERSAL ON BROADCAST SPREADERS FOR SOLID MANURE

摘要

The process of manure spreading is an important step in cultivating land for agricultural production. For this reason, the technical process of manure spreading was studied using various methods of scientific research and analysis. The focus was primarily on improving the working principles of manure spreading, using so-called wide-angle manure spreaders. Results of the analysis of material transport along the rotor revealed the most relevant parameters of manure spreading. It was found that friction is not the most important parameter. The initial position of pieces of manure and the rotational frequency of the rotor are far more important. The coefficient of friction between the rotor and pieces of manure has a minimum influence on the tangential speed of a piece on the rotor, which in turn also means a minimum influence on the range of spreading. The initial position of the piece on the rotor has an influence on the tangential speed and travel of the piece on the rotor. The tangential speed of the piece as it departs from the rotor is influenced by the size of rotor and the rotational frequency of the rotor. Included are recommendations regarding the process of constructing a new spreading device or improving existing methods of spreading manure
