Pneumatic single-grain seeder, has deployed pipes with frontal ends aligned perpendicular to central line, where line in longitudinal extension of region with its straight extension cuts circumference of drum

摘要

The seeder has deployed pipes (17) with frontal ends aligned perpendicular to a central line and linearly led into a sectional region (22) till a drum (6). The line adjacent the drum encloses an angle of 25 degrees to 30 degrees to a tangent at a peripheral surface of the drum in a seed separating apparatus. The ends have a maximum insulation thickness of less than 0.6 millimeter to a length of 25 millimeter, measured from an intersection opening (18). A line in longitudinal extension of the region with its straight extension cuts circumference of the drum.
