New resource-saving design of the sowing device for fodder crops
The creation of a solid fodder base is based on the rational use of arable lands for meadows and pastures. In the system of measures to strengthen feed production, a selection of reliable, high-yielding fodder crops that can become a source of inexpensive and high-grade fodder, as well as the development and introduction into production of highly efficient agricultural machinery that provides the implementation of new technologies for sowing, growing, harvesting the process of harvesting quality forage, balanced on all elements of nutrients. A sowing device has been developed that allows without additional material and time costs to pass from the dotted sowing to the combined method without using additional sowing discs. The structural features of the device prevent seed from crushing and crumbling. The developed method and design of the pneumatic sowing device for the combined sowing of two crops in the same row with the same intervals between the seeds and their placement at different depths of the embankment allows to obtain savings in sowing areas, improve the environmental situation of the environment, by reducing the number of passes of the unit and obtaining a balanced feed for animal protein to simplify the design, making it easy to use and financially profitable. With such a sowing device it is possible to transfer relatively easily from the combined sowing to the dotted and, conversely, without additional costs (including temporary ones), which gives significant savings in terms of material and time indices. The seeder, equipped with pneumatic sowing devices of a new design, makes it possible to obtain fodder with the content of digested protein to 105-110 g, which increases milk yield per cow to 3000 kg per year.
