Soil-cultivating ripping-separating machine working bodies of stratifier practically exclude soil lumps possibility larger than 10 mm getting into seeding zone and create necessary surface layer possibility. However, at a working depth of 3 to 12 centimeters, soil movement along ploughshare is difficult due to soil swath formed. Soil is piled-up and crumbles to sides, soil movement to ripping-separating device is deteriorating. To exclude that, passive rotating disks were installed on both sides of ploughshare. When machine is moving, flat rotating disks contribute to soil separation pressed between them from the solid mass, and to its movement along ploughshare, limit soil pileup. Distance between guide discs, which ensures soil separation, was determined depending on soil physical and mechanical properties and their course depth. As a result of the experiment at a given disks depth and soil moisture, it was determined that soil moisture of 72.1% has the greatest influence on maximum distance between disks, influence of the disks depth is 19.9%. With positive and negative angle increase of disks wheel alignment within 0°±4°, their traction resistance to movement increases. Guide discs installation at an angle to each other in two mutually perpendicular planes soil pileup increase on ploughshare and traction resistance. [ABSTRACT FROM AUTHOR] |
