The article presents theoretical studies to substantiate some parameters of the dielectric sorting device of alfalfa seeds, in particular: the width of the outlet slot of the hopper, the step and depth of the metering groove, the length of the limiter and the angle of its installation. When developing a theoretical study to substantiate the parameters of the sorting device, the physical and mechanical properties of a heap of alfalfa seeds were taken into account. Substantiated parameters make it possible to improve the design and thereby improve the technological process of sorting and cleaning of alfalfa seeds of a dielectric sorting device.
Existing plows do not provide high-quality tillage between rows of orchards and vineyards. The purpose of the study is to develop and justify the parameters of the plow for cultivating the soil between rows of gardens to tractors of class 0.9 kN. A design scheme of a single-body plow for smooth, rowless plowing of garden aisles has been developed. The proposed plow consists of a movable and fixed frame, a disc knife, a screw body with a hostage. The research uses the laws of agricultural mechanics, mathematical statistics, and methods of strain measurement. The technology of cultivating the soil between rows of gardens with a single-body plow for smooth plowing is justified. To implement the proposed technology, the position of the plow body changes relative to the tractor during operation. It is established that when equipping a plow with a movable and fixed frame and performing a body width of 45-52. 5 cm, the required plowing quality is achieved with the lowest energy consumption.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
