DETERMINING THE VELOCITY RESTORING FACTOR IN SEEDS STRICKEN AGAINST THE OPENER SPLITTER

Abstract

There was developed a method for determining the velocity restoring factor in seeds stricken against the splitter of a seeding machine by simulating a real process of seed distribution under the blade of the opener. To ensure the desired velocity of seeds when impacted, the seeds were thrown off the shelves installed at the heights of 50, 100, 150, and 200 mm to a metal plate installed at the angle of 45° and the height of 50 mm from the surface. The velocity restoring factors of seeds after hitting the plate were calculated based on average distances of rebounds. Experiments were carried out on seeds of wheat, oats, rye, barley, buckwheat, and peas. The average values of distances, at which seeds were rebounded from the splitter, and the confidence intervals were determined. The area of seed distribution relative to the average rebound was constructed. There were determined the average values of seed velocity restoring factors after the impact: wheat seeds 0.54, oats 0.46, rye 0.51, barley 0.56, buckwheat 0.51, and peas 0.65. It has been found that the seed velocity restoring factor depends on a shape of seeds, their surface, and a velocity of their attack on the plate.
