The inventor ofHocuicH is for the harvesting of raw materials & production / production, in particular for biodynamic structures, and can be used primarily in dual-drum iodotide devices.

A well-known golden device containing a rotating double drum and located under the Institute of Science of the Dec ;, formed by rods

However, such a device, when using UTB in a two-drum version (for example, after iodized devices), provides the output of biodogically valuable grains from under the first iodotyl drum as a percentage of the total number of grades of biodogically valuable grain, for iodot; as well as characterized by

1borebore; dov dv; hbarabannogo iodotidnogo device dd to undress the grain after obdomodot in two streams.

The quantitative yield of bio-grain valuables after the first drum is explained by the fact that when harvesting seed plots, a two-drum iodide device is tuned to a soft mode of operation, which is characterized by a lower linear velocity of the drum scourges and increased clearances at the entrance and exit between the laths and the drum scars.

The first threshing drum is set up in a gentle mode of operation to reduce crushing and traumatizing the bio-rich valuable grain supplied to the threshing in the first modular drum, and to weaken the impact of the whip of the drum and laths on the grain, which is wheeled in the threshing process . However, setting the operation mode to a soft mode for the first threshing drum significantly reduces the separation of the threshed grain through the concave and, accordingly, reduces the yield of the biologically valuable grain after the first threshing drum in quantitative terms. The purpose of the invention is to increase quantitatively the yield of biologically valuable grain from the threshing device, as well as to reduce the damage to the grain during threshing. This is achieved by the fact that the proposed two-drum threshing device is equipped with a concave, designed so that the transverse threshing strips of the concave are installed at different heights through one. At the same time, the tcpoMKa of each rolling plan is located under the longitudinal bars of the secondary drum, passing through the holes of the speakers, threshing 1 p: x plenok concave. This reduces the number of blows ae on the bar of the drum and drum whips, and consequently, reduces its damage4, which, in turn, increases the energy of the seed. The drawing shows a two-drum threshing vatroysevo. It contains threshing drums I and 2, intermediate b ry ter 3 about intermediate grate 4, demolition beater 5, concave mi b and 7. The last cocTOHf of protruding threshing bars B, drowning threshing thrusts 9 and rods 10 passing through the holes of the protruding threshing bars 8. When a threshing device is in operation, the bread mass is supplied by any other device under Araban I, where the most ripe grain is threshed, and the grain of the threshing grain is extracted through the concave 6, the bread mass after threshing is removed I promeutochnym beater drum 5 is provided under the drum and ii, which threshes and delivers it to the Impeller 5, Last directs the grain mass into the other working organs, e.g. solomotr p. Due to the fact that the thrashing bars of concaves b and 7 are installed at different heights through one periodically, the bread mass will make wave motion, and this, in turn, increases the amplitude of the bread grain oscillations as it moves along the wind. separation of grain through the concave. The number of protruding thrashing strips is two times less in comparison with the similar existing concave, therefore the number of grain strikes on the concave and drum flaps is reduced, which increases the seed quality of the grain. THEME OF THE INVENTION A threshing device containing a rotating mobile bar and a deck located under it, formed by transverse strips, characterized in that, in order to reduce the damage to the grain during threshing, the strips are made different in height and mounted on alternating rods.
