Modeling the parameters of a screw-type conveyor-distributor

Loading grain crops into various containers is not easy due to the impossibility of filling the entire required capacity, uneven distribution of material, restrictions on the container design, etc. The article considers the design of a screw-type conveyor-distributor used for uniform loading. The device consists of a screw placed in a casing. From below, along the entire length of the conveyor-distributor, there is a discharge hole of a particular geometric shape. The study task was to obtain the parameters of the screw-type conveyor-distributor, to determine their effect on the production parameters of the screw with known parameters of the loading capacity for ensuring uniform grain loading. In the course of a computer experiment, screws with diameters of 100, 160, 200, 250, 315, and 400 mm were examined. While their speed changed from 50 to 600 min-1 at intervals of 50 min-1, the screw length varied from 1 to 14 m in increments of 1 m. The results obtained revealed acceptable diameters and speeds of screw-type conveyor distributors depending on the dimensions of the loaded containers to ensure uniform distribution. Using the example of a rectangular warehouse with a size of 14 by 20 m, the authors determined the technical characteristics of a screw-type conveyor-distributor and determined the appropriate geometric shape of the screw casing hole to ensure uniform grain distribution.
