Abstract: 1. A method of gathering grain, comprising before threshing branch of a grain from the oblique biomass by its stirring in a combine harvester, gathering of the separated grain and its submission on the clearing, characterized in that preliminary a biomass is forward move on grater-detaching surfaces, sift and collect the separated grain, then these operations combine with stirring a biomass then in addition carry out periodic squeezing a biomass with an opportunity of regulation of its intensity and frequency. 2. The method of gathering grain as claimed in claim 1, characterized in that the gathered grain is separated according to its quality standards- separately elite grain, a grain high, average and poor quality, and also seeds of weeds. 3. A device for gathering the grain, comprising the inclined chamber with the bottom having a working surface for moving of a biomass and a trench for gathering of a separated grain and its submission in grain receptacle, the conveyor with cross rods on a tape and grain receptacle for gathering and tap (removal) of the separated grain, distinguished by what the working surface of the bottom of the inclined chamber is executed goffered, and curvilinear surface have W and V a figurative structure and settle down on a working surface of the bottom as branches within the limits of which wavy change height from h1=>10mm up to h2 = 5mm, in each branch curvilinear surface the step of a wave curvilinear surface is increased aside troop landing part edges of the bottom by size (f-r) => 10mm where f and r - steps of two adjacent curvilinear surface on a branch, from them f - are closer to troop landing part to an edge, and distances between branches curvilinear surface δ => 50mm, thus in a reception zone of the conveyor the inclined chamber contains demountable grater-detach a lattice connected with grain receptacle. 4. The device as claimed in claim 3, characterized in that branches of curvilinear surfaces are V and/or W shaped, and in V -shaped the central corner α =>15 degree , and in W -shaped internal corners β and φ => 10 degree . 5. The device as claimed in claim 4, characterized in that the working surface of the bottom of the inclined chamber is punched in hollows curvilinear surface for receipt of the separated grain through punching in a trench located under a working surface of the bottom. 6. The device as claimed in claim 5, characterized in that V and/or W shaped branches of curvilinear surfaces are directed to tops aside, opposite to a direction of moving of the bottom branch of the conveyor, and the trench is located in an average part of the bottom of the inclined chamber and executed with the width increased aside of a reception zone of the conveyor. 7. The device as claimed in claim 6, characterized in that the bottom of the inclined chamber contains two lateral trenches in addition to a trench in the average part, executed with an opportunity of receipt in them grains on inclined branches curvilinear surface, punching of a working surface of the bottom are executed on an axial line of the bottom in hollows curvilinear surface, and V and W -shaped branches of curvilinear surfaces are directed to tops aside troop landing zones of the conveyor. 8. The device as claimed in claim 5, characterized in that a trench the bottom of the inclined chamber contains an additional trench, and both trenches are executed lengthways troop landing edges of the bottom with an opportunity of receipt in them grains on inclined branches curvilinear surface, and branches of curvilinear surfaces are V -shaped with the tops directed aside troop landing of a zone of the conveyor. 9. The device as claimed in claim 3, characterized in that the trench of the bottom of the inclined chamber is located along the right or left lateral edge of the bottom with an opportunity of receipt in it grains on inclined branches curvilinear surface, and branches curvilinear surface are executed rectilinear, inclined to the right or to the left with a corner of an inclination to a plane of cross section of the bottom θ => 10 degree . 10. The device as claimed in claim 9, characterized in that the trench of the bottom of the inclined chamber is executed with division into compartments for gathering a grain of different quality. 11. The device as claimed in claim 3, characterized in that the working surface of the inclined chamber has branches curvilinear surface, executed V and W figurative with different orientation of an orientation of tops, and also rectilinear inclined to the left and to the right in any combinations. 12. The device as claimed in any of claims 3-11, characterized in that the bottom of the inclined chamber is executed demountable. 13. The device as claimed in claim 3, characterized in that grater-detach the lattice is fixed to the case of the inclined chamber with the help of the hinge with an opportunity of regulation of a backlash for the miss of a biomass between the mentioned lattice and rods of the conveyor. 14. The device as claimed in claim 3, characterized in that grater-detaching the lattice is executed as rod or penetrative separable, or jalousie sieve with an opportunity of regulation of a degree jalousie a venetian blind. 15. The device as claimed in claim 3, characterized in that in different height curvilinear surface case use a set, connected among themselves, bent alike shelf corner, and the degree of increase of wear resistance of the bent part is more than at high-altitude corner. 16. The device as claimed in claim 3, characterized in that with the purpose of decrease (reduction) of power consumption of process of submission of a grain, top V-shaped curvilinear surface with a trench transportations of a grain capacity are executed on a diagonal aside. 17. The device as claimed in claim 3, characterized in that curvilinear surface are executed with extending aside a reception zone of the conveyor. 18. The device as claimed in claim 5, characterized in that with the purpose of increase of mechanical orientation fast sliding grains to sifting apertures, the last are executed as figured opening with inclination downwards aside an entrance part openings and a ledge upwards on their opposite parts. 19. The device as claimed in claim 5, characterized in that with the purpose of activization of allocation of a free grain a bottom of the inclined chamber is supplied with the punched sheet, established from both sides of a goffered surface or on its middle. 20. The device as claimed in claim 5, characterized in that with the purpose of decrease (reduction) of a contamination of grain lots, the trench is supplied fixed on it separable with a surface established with an inclination aside to sideways the inclined chamber. 21. The device as claimed in claim 16, characterized in that the power shaft of working body, for the subsequent transportation of a grain is supplied safety muff, and capacity for a grain - the signalling gauge. 22. The device as claimed in claim 21, characterized in that the working body for the subsequent transportation of a grain is attached to the bunker hinge, with an opportunity of moving concerning it. 23. The device as claimed in claim 21, characterized in that in quality transportation grains use flexible working bodies, for example flexible worm conveyor etc., and capacities of a grain - parts of the bunker of a harvester (combine). 24. The device as claimed in any of claims 3-23, characterized in that with the purpose of separate clearing a grain the trench is supplied transportation grain lots, and system of clearing (roars and sieving base) - adjustable on width directing dividing surfaces with reflectors and " the shared zone of clearing " with transportations in the grain bunker; except for that the part of the bunker contains dashboard revealed at a unloading worm conveyor grains from "the shared zone of clearing" in the module of a vehicle.
