Abstract

The qualitative indicators of seed dressing in the pre-sowing autumn or spring periods depend on the degree of their contamination with impurities. The essence of the presented development is aimed at improving the technological process and working parts of modern seed treaters, ensuring the removal of dust and impurities from their flow when entering from the loading inclined auger into the bunker, by supplying and placing above it a receiving dust-air chamber in the form of a tetrahedral regular pyramid with oval corners. The pyramid is connected through a window to a loading auger and windows placed on two opposite side faces with sockets built into them - air intake and dust intake, connected by an elastic sleeve to a cyclone attached to the side of the hopper. Its upper part is connected through an air duct to an electric exhaust fan, and the lower part is connected to a removable dust collector. The degree of cleaning of seeds from dust and impurities in this position before they enter the dressing chamber promotes the penetration of drugs into the inside of the seed and, accordingly, increases their germination and the yield of the cultivated crop by 15-20%. In addition, the machine is easy to use both during operation and during maintenance in general, including storage.
