“…Речь идет об устройствах отвода скошенной хлебной массы от колес МЭС. Для перемещения срезанных стеблей от технологических разрывов транспортера порционной жатки, соответствующих расположению колёс МЭС, целесообразно применять устройства отвода массы, которые представляют собой шнековые делители [2]. Витки шнеков могут быть правого и левого направления [7,8].…”

“…4). Тогда, учитывая геометрические размеры ширины с части транспортёра, на которую шнек перемещает массу (ширина боковой ленты транспортера порционной жатки) и ширины захвата шнека b, можно записать условие, при котором стебли не будут испытывать излишнего трения о названную выше стенку [2]. На схеме, представленной на рисунке 4, стенка, располагающаяся за шнеком, обозначена линией BC.…”

In this paper we consider the structural and technological process of the combine used in the process of separate harvesting of grain crops, as well as a number of its parameters. Among the main units of the combine, we allocate a conveyor and devices for removing beveled stems from under the wheels of the vehicle. The principle of operation of the conveyor at different phases of the Reaper and especially the removal of cut stems from under the wheels of the vehicle during operation of the Reaper. The results of theoretical studies on the establishment of the optimal design of the parameters of the belt conveyor are presented, the ranges of their optimal values are considered and determined. Studies on the establishment of optimal parameters of the screw divider in the Reaper, which is the main component of the device for removal of beveled stems, are presented. Taking into account the optimal design and mode of operation of the screw divider, the correct work is provided to remove the cut stems from under the wheels of the harvester.

BACKGROUND:The 15-20% of the product of machine harvesting of cabbage are cabbage leaves and the remains of weeds. Known devices installed at cabbage harvesters for separating associated waste products do not operate with sufficient quality. In this regard, a new separating device has been developed. AIMS:Assessment of the effectiveness of operation of a new separating device in assembly with a cabbage harvester in laboratory conditions. MATERIALS AND METHODS:In order to carry out the research, a separating device made in the form of a rotating roller is in-stalled above the web of the conveyor-cutter of the experimental cabbage harvester with a gap be-hind the unloading zone of the cutting device at the angle to the direction of the cabbage flow. Under laboratory conditions, the working process of the device was studied by supplying a mass of cabbage (heads and cabbage leaves) to the rotating roller, driving the blocks of the cutting device and the conveyor-cutter of the cabbage harvester from the electric motor. RESULT:As a result of the experiments carried out under the PFE-22program, the dependence of the opera-tion quality (the degree of separation of cabbage leaves from heads) on the leaves percentage and the size-mass characteristics of heads in the flow was studied. At the same time, it was found that the developed device as a whole operates steadily, the process of separation of associated waste products proceeds most successfully with small and medium sizes of heads and a lower content of cabbage leaves in the flow. CONCLUSIONS:The developed device separates the associated waste products from heads of cabbage sufficiently in the entire range of their content in the flow from 10 to 20%, which is typical for real field conditions.
