METHOD OF SETTING WORKING BODIES OF SELF-PROPELLED GRAIN HARVESTING COMBINE Russian patent published in 2015 - IPC A01D41/127 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture and can be used in regulation of the working bodies of grain combine harvesters. The method of setting the working bodies of self-propelled grain harvesting combine is characterized in that the common discrete statistical information is entered to the on-board computer of the combine harvester, collected according to the test results of similar models of self-propelled grain combine harvesters, on the parameters: the efficiency of the combine work Y (W, q_m, q_a, C, D, T), where W is the performance on grain, q_m is the loss behind the thresher, q_a is the loss behind the adapter, C is the value of foreign impurity in the hopper, D is the value of crushing grain, T is specific fuel consumption; agricultural background Z (Y, M_g, M_s, D, D_s, S), where Y is grain yield, M_g is grain moisture, M_s is straw moisture, D is debris of field, D_s is down standing crops, S is shrivelling of grain; setting of the combine X (V, n_b, n_o, s_e, s_a, s_o, s_u), where V is velocity of the harvester, n_b is speed of the threshing drum, n_o is the speed of cleaning fan, s_e is the gap at the inlet of the threshing device, s_a is the gap at the outlet of the threshing device, s_o is the value of opening of the upper sieve blinds, s_u is the value of opening of the lower sieve blinds. The mathematical model is made taking into account this information Y (W, q_m, q_a, C, D, T)=f{Z (Y, M_g, M_s, D, D_s, S), X (V, n_b, n_o, s_e, s_a, s_o, s_u)} ensuring the implementation of the technological process on the parameters (W, q_m, q_a, C, D, T). The settings parameters (V, n_b, n_o, s_e, s_a, s_o, s_u) are calculated, solving the problem of optimisation on one of the performance indicators, with restrictions on the parameters of agricultural background (Y, M_g, M_s, D, D_s, S) and settings (V, n_b, n_o, s_e, s_a, s_o, s_u). Then according to the results of the ongoing work of the combine a new discrete statistical information of Yi, Zi, Xi is obtained, with the subsequent restructuring of the mathematical model Yi=f (Zi, Xi) and the calculation in it of new setting parameters (V, n_b, n_o, s_e, s_a, s_o, s_u)_i, with the solution of the optimisation problem according to one of performance indicators each time at regular intervals.

EFFECT: when setting up the working bodies of the combine its efficiency of operation is increased.
