| الوصف: | The article is devoted to the current issue – improving the quality of planting seeds of grain crops. It is noted that the major designs of shovel and disc coulters have significant traction resistance, form a wide furrow, which is difficult to close, and do not provide high-quality following of the field relief. All this negatively affects the uniformity of the distribution of grain seeds, both along the length of the row and the depth of placement. The most promising direction for improving the quality indicators of the sowing unit is to equip grain planters with combined coulters. The article presents a brief description and results of acceptance tests of the S-7,2PM4 (С-7,2ПМ4) grain planter with new combined single-disc coulters developed by the Penza State Agrarian University in cooperation with JSC (AO) "Radiozavod", Penza. Acceptance tests were conducted by the Federal State Budgetary Institution "Volga MIS" (Kinel, Samara Oblast) in the fields of LLC Agro-Industrial Complex "Komsomolets" Kinelsky district of the Samara Oblast in accordance with GOST 31345-2017 "Agricultural machinery. Tractor seeders. Test methods" [1-6]. At the same time, an agrotechnical, energetic, operational, technological and economic assessment of the seeder was carried out. During acceptance tests, it was found that the combined single-disc coulters with gauge-wheels and the S-7,2PM4 (С-7,2ПМ4) seeder reliably perform the technological process. At the working speed of the unit – 7.5-10.0 km/h, the number of seeds covered at a given depth was 87.2-89.2 %, the traction resistance was within 9.45-9.47 kN. It corresponds to tractors of the traction class 1.4. Labour costs were 0.27 work h/ha, while the total cost of money at the price of the seeder – 1241.67 rubles, amounted to 885.69 rubles/ha. |
