Compliance with the sowing technology is the basis for the cultivation of any agricultural crop, since the yield and product quality, material and monetary costs, the seeding rate, the area of plant nutrition, as well as the design features of the machines used, depend on it. When sowing sugar beet, this issue is most relevant because recently, the sowing of this crop has undergone major changes. Most of the seeds used in Russia are both granulated and single-sprout. The seeding rate is set at the final density and, therefore, a delay in the growth of individual plants is not permissible. In this regard, serious requirements are imposed on the design of the seed sowing apparatus, one of the indicators of which is to ensure the placement of seeds on the loose bottom of the sowing furrow, backfilling it with soil from above with subsequent compaction creates unfavorable conditions for seed germination.

The paper presents and describes the developed design of the working elements of the roll-belt press. The theoretical dependences of the energy parameters of the press are found. The optimal operating parameters are substantiated, which allows the most efficient berry juicing. The data of experiments on berry juicing, depending on the juicing pressure and the holding time of the pulp under pressure, are given.

In the Tambov region, due to the widespread introduction of promising technologies for growing sugar beets, its yield has significantly increased, at the same time, the used seeding machines are not always able to provide the required depth of planting seeds, which leads to loss of yield and difficulty in applying fertilizers. In the course of previous studies, it was determined that with an increase in the angle of the scraper over 60 degrees, an increase in the percentage of filling the cells of the disc with seeds in various hybrids occurs, so research has established that in the hybrid PMC-120 at an angle of installation of the scraper of 70 degrees, 100 percent of the cells are filled with seeds, while in hybrids XM-1820 and Troika, the cells were filled only by 93.3%. It should also be noted that the PMC-120 hybrid with a scraper angle of 70 degrees had the lowest damage to the pellets - 0.67%, while the XM-1820 and Troika hybrids had 0.83 and 0.73%, respectively. With an increase in the angle of installation of the scraper over 80 degrees, the percentage of damaged seeds increased from 0.4 to 0.66%, on the basis of this, the design of the seeding device was proposed and theoretically substantiated, a feature of which is the reverse rotation of the seeding disc, while the rear wall of the opener is made in the form of a parabola appropriate trajectory of movement of seeds, which ensures their distribution in the immediate vicinity of its rear wall, thereby reducing the risk of falling asleep to the bed of the furrow before the granules get there. It has been determined that the trajectory of the granule movement directly depends on the angular speed of the seeding disc, which in turn depends on the geometric characteristics of the cells of the seeding disc. It is theoretically substantiated that the speed of the seed in the disc cell is determined by the sum of the projections, which makes it possible to calculate the curved surface of the opener.
