The quality of seed dosage to the furrow depends on the uniformity of seeds location on the seed disk. A new design of a seeding machine which provides better sowing was suggested at the Department of Agricultural Machinery of Central Ukrainian National Technical University. The main feature of the new seeding machine is the application of the seed disk with a peripheral arrangement of cells with the blades on its inner surface. The blades are used for the forced seizure of the seeds by the disk in the working chamber and their further transportation to the dropping zone. In order to determine the rational parameters of the seed cells of the seed disk, an experimental appliance was made and studies were conducted to determine the desired value of the coefficient of filling cells with seeds of different sizes. The experiments were conducted using disks with cell radii of 5.0 mm and 6.0 mm which correspond to their areas of 9.6 mm2 and 16.3 mm2, respectively. The vacuum in the vacuum chamber was 0.2 kPa and the peripheral velocity of the cells was 2 m/s. Taking into account the experiments conducted, it can be stated that in order to ensure the seeding of sugar beet, the radii of the cells' rounding should be within the limits of 5…6 mm which in general is consistent with the results of theoretical studies. According to them the radius of the whole is 5.7 mm. [ABSTRACT FROM AUTHOR] |
