Abstract
Preliminary separation minimizes damage of free grain by the working parts of the thresher when stripping standing crops. For this purpose, it is advisable to use the inclined chamber of a combine harvester. The purpose of this study is to evaluate the separating ability of a rotary separator depending on its design parameters and operating mode. The research included two stages. In the first series of experiments, the distance between the rod rings was changed (6; 8; 10; 12, and 14 mm), in the second series: the peripheral speed of the rotor surface (1 to 3 m/s). Experimental studies were carried out on winter wheat of the “Moskovskaya 56” variety with a moisture content of 12%. The inclination angle of the experimental installation body in all variants of the experiment was 45°, and the supply of stripped grain heap was 1 kg/s. Based on the results of laboratory studies, it was established that the intensity of separation of free grain increases as the distance between the rod rings of the device increases and the peripheral speed of the rotors decreases. The maximum passage of loose grain (100%) corresponds to a peripheral speed of the rotors of 1 m/s and a distance between the rod rings of 14 mm. The reserves for increasing the productivity of a rotary separator are an increase in the diameter of the rotors and a decrease in their peripheral speed. When these parameters change by 30 to 35%, the transport capacity of the inclined chamber remains at an acceptable level.
