Abstract
To reduce losses and improve the quality of harvesting of pasture plant seeds by isolating biologically valuable seeds and reducing the degree of their injury, it is necessary to re-equip the serial inclined chambers of the combine harvester. By dismantling the necessary components of the inclined chamber with the spacer of the experimental installation, it is possible to study the leveling of the granary biomass by each of the feeding organs separately, and when they are put in place - in a complex. The principles of reducing the loss of seeds and their injury by preliminary isolation of free seeds from the mown crop mass, as well as pre-threshing destruction of the connection of ripened seeds with the stem are implemented in the design scheme of the combine harvester. With a quadratic regression equation of four independent variables, we can convert it to canonical form and analyze multi-dimensional view of the response surface in the investigated region of the factor space, and find the zone settings in which the response is extreme. Sum of squares due to regression (SSR) to complete the destruction of com double µ and the degree of leveling wheatgrass biomass v, is about 93% of the total sum of squares (SST), and for the degree of separation of spikes λ - 89,5%. Therefore, taking these coordinates for the optimal solution and converting them into natural scale, the following parameters improved feeding channel: supply of biomass q = 2,57 kg / pm; the length of the fracture L = 58,73 cm; angle of attack a = 25,76 corrugation deg.; height of the corrugation h - 19,62 mm
