Research of high-performance harvesting and transport equipment

“…This is explained by the fact that at high speeds, the bulk material (grain), thrown by the centrifugal force to the inner surface of the pipe, fills the grooves [6]. Since they are located quite close to each other (after 30°), a braking layer is formed at the surface, under the influence of which the circumferential component of the speed of the absolute movement of the grain decreases, and the axial component increases [6,7,10]. Let's analyze the flow of grain into the screw depending on the speed of the screw.With some assumption, we assume that the condition under which the largest amount of material will pass into the intake chamber is expressed in [11,13]:…”

“…The grain harvested during this period has the best sowing and food qualities.Grain harvesting by modern combine harvesters begins no earlier than 7-10 days after reaching the maximum yield by dry weight of grain. To ensure the sustainability of the process of harvesting and processing the grain crop in various regions of the country, a complex of technological, technical and organizational measures is necessary, the implementation of which should determine the economically justified degree of risk, taking into account the natural, climatic and production conditions.The most rational way to increase the productivity of a screw screw conveyor, which allows you to create a small-sized structure, is to increase its speed [1,8,15]. The productivity of the screw also depends on the uniformity of the grain supply.…”

“…In addition, when working with them during loading directly from the shoulder, manual labor or additional equipment is required. When the grain is captured from the mound, with an increase in the speed of rotation of the spiral, it is scattered, and resistance to axial movement is created inside the casing [3,7,9]. As a result of excessive mixing of the material and turning of the grain inside the spring screw.…”
