STUDYING A DISK SOWING DEVICE AND JUSTIFICATION OF ITS PARAMETERS
05.20.01 Technologies and means of mechanization of agriculture (technical sciences)
Description
In recent years, in the conditions of the Tambov region, thanks to the widespread introduction of innovative technologies, the yield of root crops of this culture has significantly increased. The scheme of sowing is the basis of technology of cultivation of any crops depend on the productivity and quality of products, material and monetary and energy costs, density of sowing, supply area and design features used cars. According to academician V. I. Edelstein, the optimal sowing scheme is able to provide an increase in crop yields up to 40%. It was noted that the most optimal scheme of sowing is a tape, with the use of which it is possible to achieve a reasonable compromise between the possibility of rational thickening of plants in order to increase yields and improve the working conditions of agricultural machines. The relevance of the research lies in the modernization of the sowing apparatus of the beet seeder SST-12B, under the belt scheme of sowing with a staggered arrangement of plants in two adjacent lines of the tape and the study of its design parameters. The analysis shows that with an increase in the angle of installation of the scraper over 60 degrees, there is an increase in the percentage of occupancy of the disk cells with seeds in all studied hybrids. Studies have found that the hybrid RMS-120 at the angle of installation of the scraper 70 degrees is 100 percent filling cells with seeds, while hybrids XM-1820 and Troika cells filled only 93.3%. This is due to the fact that the seeds of the domestic hybrid were more aligned in diameter compared to the seeds of foreign firms. It should also be noted that the hybrid RMS-120 with a scraper angle of 70 degrees was marked by the lowest damage dragees-0.67%, while hybrids XM-1820 and Troika values of this indicator were 0.83 and 0.73%, respectively. By increasing the angle of installation of the scraper over 80 degrees, the percentage of damaged seeds increased from 0.4 to 0.66%
