摘要：
FIELD: agriculture.SUBSTANCE: invention relates to devices for cleaning grain and seeds of various agricultural crops by means of an air flow and can be used by design organizations in determining the optimal design and technological parameters of the pneumatic separating channel and other elements of the pneumatic system connected to it. Method for determining the path of movement of a particle of grain material in a pneumatic separation channel includes simulating the distribution of airflow velocity vectors in a longitudinally vertical plane, calculation and construction of the trajectory of the particle of grain material, taking into account the uneven distribution of the velocity vectors. Simulation of the distribution of airspeed velocity vectors is carried out by an experimental-analytical method containing the measurement of the actual magnitude and direction of airflow velocity vectors at a nominal grain load in the centers N of equal rectangles located in the longitudinal-vertical plane.EFFECT: incr
