Abstract

A machine for applying pellets and powder, especially micropellets, to the soil, incorporating, first, a reservoir with outlets, second, ridge wheels that are rotated by a drive shaft at varying rates and the distribute uniform volumes of the material flowing out of the reservoir through the outlets into exit pipes that communicate with a blower and that have outflow openings, and, third, base plates below the ridge wheels. To ensure uniform application of material that tends to clog up the ridge wheels the machine is provided with scrapers that are intended for cleaning the ridge wheels, that engage the depressions between the ridges, which are positioned one after the other in the sense of rotation, and that are appropriately constructed to scrape the depressions out.
