The paper presents data on the separation of two-component mixtures of agricultural seeds by means of low-frequency horizontal vibration. Experiments were carried out with beans, peas and sunflower seeds. Modelling of the separation process of mixtures by the method studied in this work shows that the trajectory of a particle is a vortex along an ascending or descending line, depending on the combination of the properties of the components and operating parameters. The studies have shown that the minimum time for complete separation of the mixture into components is achieved when the container inclination angle is approximately equal to the repose angle of mixture components. The separation process is carried out only at amplitudes smaller than the particle size of the mixture.

“…And bulk materials under the influence of vibrations and vibrations, under certain conditions can behave both as a solid and as a liquid [7,8,9]. In this work, an attempt is made to use the above-mentioned properties to describe aspects of the process of cleaning planting seed material from weed seeds [10]. Let's consider a vibrating cylindrical container of seed material.…”

The article deals with the optimization of cleaning grains and seeds of agricultural crops from weed seeds. The process of cleaning grain material by one-dimensional horizontal vibrations depends on the friction coefficients of the seeds against each other. It is optimized by selecting the amplitude and angle, relative to the vertical, under which the cylindrical container containing the grain mixture is located. Experiments were carried out with almost all types of seeds most widely used in the domestic agricultural industry. The cleaning process was investigated only at amplitudes smaller than the seed size. The seeds of cultivated plants and weeds move upward or downward, depending on the specific gravity. Calculations show that with correctly selected values of the amplitude and angle, the average trajectories of the grains are practically straight lines parallel to the generatrix of the cylinder containing the seeds. Studies have shown that the maximum cleaning speed is achieved under the condition that the angle of inclination of the cylindrical vessel is equal to the natural slope of the seeds with the highest specific gravity.
