BACKGROUND: Mechanized pulling of crops is carried out by the most efficient flax milling machines with transverse belt-disc channels. At the same time, the analysis of the works showed that the action of the inertia forces of plants when moving in curved pulling channels is not analyzed, their effect on the quality of the technological process is not found, the condition for pulling all plants from the soil without their excessive flattening, which reduces their effectiveness, is not determined.
OBJECTIVE: Theoretical and experimental study of the process of pulling flax plants with devices with transverse belt-disc channels.
METHODS: Experimental studies were carried out according to well-known and developed methods, with an assessment of flax products according to the GOST standards. The influence of the centrifugal inertia forces of plants on the bending of the plant belt, stretching of its upper part and loss of flax balls, and the condition of pulling all plants, taking into account the maximal strength of the tearing resistance of plants, were determined. Standard equipment and developed installations were used.
RESULTS: Dependences were obtained for determining the inertia forces of plants in the zones of pulling pulleys and deflecting rollers, and bending moments created by the inertia forces of plants and acting on plants, as well as the speed of the pulling belt, to prevent greater inertia forces of plants, negatively affecting the quality of work, and the condition of pulling all plants from the soil with taking into account the maximal strength of the stretching resistance. The limit value of the bending angle of the plant belt, which should not exceed 20°, has been found experimentally.
CONCLUSIONS: When designing flax milling machines with belt-disc channels to reduce the inertia forces, it is necessary that the elements of adjacent milling sections have the same size and shape as possible, which will reduce the forces of inertia of plants, eliminate peak pressures in a channel, increase the durability of the belt, reduce losses of flax products.
