The materials of the article are devoted to an urgent problem - to reduce losses and crushing of grain by the threshing apparatus of a combine harvester by improving the design and substantiating the operating mode of the conveyor inclined chamber of the header. It describes the design of the proposed chain-slat conveyor for the feeder chamber of the combine harvester, the methodology and results of laboratory studies to substantiate its design parameters and operating mode. Laboratory studies were carried out on a developed experimental setup using the method of planning a multifactor experiment. As an optimization criterion, the degree of uniformity of the distribution of the stalk mass was taken when feeding it into the threshing apparatus of a combine harvester. As a result of laboratory studies, the optimal values of the following parameters were established: the pitch of the stamped strips of the conveyor of the header feeder chamber t_p = 307.2 mm; feeder chamber conveyor speed ϑ_tr = 3.5 m/s; working speed of the combine ϑ_k = 2.0 m/s.
