摘要
A stand for investigating the characteristics of the apparatuses of precise sowing the seeds is executed in the form of a frame with a housing of seeding machine, seed bunker, conical drum with cells concentrically placed on the periphery of its lower base, said cells are placed evenly along the circle to match the size with rear wall at an angle ? to the radius of conical drum, vertical drive shaft and drive. The groove is executed in the middle of thickness of outside diameter of conical drum, in which is mounted the pusher of seeds with sheared end at an angle to the direction of ejection of seeds. Opening for removal of seeds from the bunker is executed under pusher in the area of ejection. Under opening on hinges through parallelogram suspension with vibration drive at an angle to thehorizon, value of which exceeds the angle of friction of material, several sieves-separators are mounted with possibility of oscillatory motion, for example, three sieves-separators. In this case, the openings of upper sieve-separator is less than the greatest fraction of seed material, the openings of the second sieve-separator is less than the smallest fraction of seed material, and the openings of the third sieve-separator is equal to half of the external diameter of seeds. On the sieves-separators from two sides are mounted the limiting laths for guaranteeing the retention of seeds, under each sieve separator are installed the containers for collection of corresponding fractions according to their size.
