METHOD OF CALCULATION AND DESIGN OF SOIL DISPENSER

The article considers a dispenser-distributor with soil-transporting elements, substantiates and determines its technological and design parameters. As a result of the theoretical studies carried out, analytical dependences were obtained to determine the diameter of the disk of the soil dispenser-distributor, the height of the soil-transporting element and the volume of soil required to cover potato tubers. The results of work in the field of theory and calculation of potato planters are systematized and generalized, analytical dependences are obtained to determine the main design and technological parameters of the soil dispenser-distributor of the potato planter. Based on literary sources, to obtain digital values, we chose the row spacing (70 cm), the distance between tubers (25 cm), the weight of the tuber is average (55 ... 60 g), the width at the bottom of the furrow, equal to the width of the nest, is the smallest (0 06…0.07 m), tuber planting depth (0.19 m), potato fraction – seed (50…80 g), operating speed – within (2.9…9 km/h). According to the calculations, the following results were obtained: the diameter of each disc (D=35…40 cm), the height of the soil-transporting element (hpe = 0.025 m) and the volume of soil (Ω= 0.004 m3) required to cover potato tubers.
