Machines used in world practice for surface application of mineral fertilizers are often equipped with centrifugal devices with vertical or horizontal location of the axis of rotation. Having high productivity and reliability of technological process, they cannot always provide reception of a necessary dose and uniformity of scattering of fertilizers on width.
In Ukraine, currently produced machines for the application of mineral fertilizers, which we have not previously produced. Since about 2/3 of all available mineral fertilizers, as well as most of the limestone and gypsum-containing materials are applied in a continuous manner, it is necessary to have a certain fleet of machines for applying fertilizers available to consumers. Fertilizer application in a continuous manner is carried out by land and aviation.
One of the main agrotechnical requirements for machines for the application of bulk materials (mineral fertilizers) is their uniform distribution on the field surface. From uneven application of fertilizers, the reduction in grain yield reaches 10 ... 15%.
The main disadvantages of the machine for applying mineral fertilizers are: imperfect design of the spreading mechanism, which leads to uneven scattering of fertilizers on the field surface; a large number of gears, which affects the metal content and cost of manufacture and complicates the design.
Chain transmissions that drive the spreading device and the conveyor (during operation the chain is stretched, which requires the use of tension rollers, and take-off from the sprockets, especially on the drive of the spreading device); significant uneven application of fertilizers due to imperfect design of the spreading disc.
The main reason for the low quality of fertilizer distribution by scattering machines, most researchers see a significant impact on the technological process of external random factors: field relief, wind speed and direction, humidity, elastic, frictional, hygroscopic and particle size distribution of fertilizers. Therefore, the improvement of the technological process of fertilizer scattering, in order to ensure a given uniformity of their distribution on the field surface in the conditions of real functioning, is an urgent scientific and practical task. In order to eliminate these shortcomings, a new spreading working body is proposed.
