Abstract

Abstract. The purpose of the research: to determine the effect of the threshing mechanism parameters of combine harvester on the efficiency of the threshing process of grain crops according to the analysis of the threshing mechanism process. The object of research is the operation of the drum threshing mechanism for combine harvester. The subject of research is the correlation between the threshing mechanism parameters for combine harvester and the efficiency parameters of grain crops threshing.
The simulation of the threshing mechanism process investigated the selection of grain from the ear by blow and moving in the threshing mechanism, as well the grain separation through concave. 

There are analyzed during research of the threshing and separation process of grain in the threshing mechanism the kinetics of the process to take into account the resulting blow speed of the threshing drum on the ear and the speed of mass movement and pressure in the threshing area. The relationship between the main parameters of threshing mechanism is established during the analysis of the technical characteristics for modern grain harvesters according to information brochures of firms.
Results: the model of the threshing process in all stages; the unevenness of grain threshing and separation in threshing mechanism along the concave; the correlation between the basic parameters of threshing mechanisms of modern grain harvesters.
Key words: combine harvester, threshing, separation, threshing mechanism, concave, parameter.
