THEORETICAL JUSTIFICATION OF FORCE NEEDED TO MOVE THE SOWING SECTION OF THE PLANTER RAISED BED

Abstract

Developed by ridge planter, each section of which is equipped with paw-Coulter, two working bodies with flat discs and roller. Application of raised bed planter allows for simultaneous pre-sowing cultivation, sowing seeds, education on line sown seed tubercle of the soil, compaction of mound soil on three sides, and finally form a ridge of soil to the desired dimensions and density of soil in it. The article considers the process of formation of the crest of the soil working bodies of the planter raised bed, as well as in theory the force required to move one section of the raised bed seed planter. The research identified that each of the sowing section is in the process of rectilinear movement raised bed planter works in «floating» mode, therefore, the weight of the sowing section, with mounted working bodies, the support-drive wheels raised bed planter does not have significant influence and can be neglected. The weight of the frame sides of the sowing section, installed on the paw-opener and two working bodies with flat discs, have on the support wheel of the sowing section, and loosening the soil with a paw-coulters and sweeps the working bodies with flat discs occurs without a turnover of the reservoir. Additional vertical load of the compression of the spring roller, evenly distributed on the press ring (50 %) and spherical discs (50 %). Theoretical studies of the process of ridge for sowing allowed to reveal that the force required to move one of the sowing section of the planter raised bed, hanging from the weight of the seed section, the speed of displacement of the depth of the tines and coulters of the Lancet paws working bodies with flat disks in the soil, the geometrical dimensions of the wheels, the parameters of working bodies, as well as physico-mechanical properties of the soil.
