High-performance Sieves (UVR), which significantly increase productivity, significantly reduce losses and obtain cleaner and higher-quality grain during the operation of grain-harvesting equipment. The set of Universal High-Performance Sieves consists of an upper, lower and extension sieve made of high-alloy steel with a polymer coating, which increases the service life several times longer than serial ones. With installed UVR grates, the production potential of theharvester is used to the maximum. UVR combs are tin plates with multiple aerodynamic channels. Air passing through separately open UVR combs is distributed, stabilized from the beginning to the end of the sieves, evenly distributing the straw mass over the entire area of ​​the sieves. Eliminating traffic jams, intensively moving the mass (during turns, slopes), UVR grates (ver. lower) open more strongly than ordinary grates, and require a more powerful air flow (the number of revolutions of the fan is increased by 200-350 revolutions). The increased wind flow increases throughput (when turning, slopes), reduces losses on sieves up to 30-50%, cleans grain approximately 30-50% more accurately than the original ones. Sieves with UVR combs have a high level of self-cleaning, they practically do not become clogged (barley ears, wet rapeseed, haircorns for grain, short straw, etc.). UVR sieves are almost always used forharvesting grain crops with a permanently set maximum fan power for all types of crops. In this way, UVR sieves significantly increase the profitability of threshing and contribute to increased productivity.
