In this work, a study of the gravitational movement of grain mass along the shelves of a cascade installation was carried out, aimed at developing and substantiating an analytical model of controlled gravitational movement of grain along three adjustable transfer sections with the corresponding ratios of their inclination angles.When loading, grain falling from a considerable height, hitting the bottom and walls of the container, can be injured.This problem requires the development and study of a technical solution that would provide regulation of the speed of grain movement when loading it into the container. Devices designed to reduce and stabilize the loading speed should not be complicated in their manufacture and operation. The proposed model takes into account the initial height of the grain fall onto the first acceleration section, the height of the grain fall from one shelf to another, the length of the transfer shelves, as well as the friction coefficient between the grain layer and the material of the shelves.Based on the developed analytical model of grain movement and the proposed equations for finding the relationships between the three angles of inclination of the transfer shelves, a schematic diagram of a gravity installation with three shelves was proposed. The shelves can freely rotate on their axes to the required angle relative to the horizontal plane.For the first shelf, the angle of inclination α was chosen from the variational series of 45°, 55°, 65° and 75°. For the angle β, its maximum variation does not exceed 0.59°, and the angle γ changes in its maximum value by 1.4°. At the same time, the difference between the values of the angle γ for different ranges can differ by more than 10°. The results obtained and their analysis indicate that the presented analytical model and the corresponding gravity-cascade installation due to three sections allow solving the problem of controlled grain velocity movement for loading it into containers without injury.
