Laboratory studies of the sowing unit with the grooves of the coil made in the shape of a torus

Abstract

The article is devoted to improving the quality of sowing seeds of grain crops and contains the results of laboratory studies of the coil sowing apparatus with the grooves of the sectional coil made in the form of a torus. The paper presents the optimal design and operating parameters of the coil sowing machine with the grooves of the sectional coil made in the form of a torus to ensure the best uniformity of the distribution of seeds along the length of the row. A multifactorial experiment was carried out to substantiate the optimal values of the design and operating parameters of the coil sowing apparatus. The dependences of the uneven distribution of seeds along the length of the row on the speed of the coil, the radius of the forming circle of the torus and the thickness of the separation disk of the spool-sowing apparatus are established.
