Study of injury of loose material of agro-industrial production by working bodies of flexible screw conveyors

Abstract

Purpose. Determination of the rational parameters of the process of transportation by the working bodies of flexible screw conveyors with the least trauma to the loose material of agro-industrial production. Methods. The methods of probability theory, mathematical statistics and regression analysis were used for research. Experimental studies of injury of loose material of agro-industrial production depending on the mass of the flexible working body, its rotation frequency and the height of lifting the material. Results. In order to determine the injury of loose material, an experimental setup was developed to study the process of material transportation by flexible wire conveyors. When conducting a multifactorial experiment to determine the injury of loose material of agro-industrial production by the working body of a flexible screw conveyor, the variable factors were: the mass of 1 m of the working body m, the frequency of rotation of the flexible working body n, and the height of lifting the material h. Based on the results of experimental studies, appropriate regression equations and response surfaces were constructed to establish the influence of controlled factors on the injury of loose material of agro-industrial production. The obtained regression equation can be used to determine the injury of grain Y during transportation by a flexible screw conveyor with a sectional working body. Conclutions 1. The method of conducting experimental studies of injury of loose material of agro-industrial production by the working bodies of a flexible screw conveyor has been developed. 2. It was established that the mass of the working body has the maximum influence on the injury of loose material. The next in intensity of influence is the frequency of rotation of the working body. The height of the unloading main has the least significant influence. 3. However experimental studies were conducted for the maximum lifting height of the unloading line h = 1.8 m, which is sufficient for loading machine planters. With a further increase in the value of h, there is a significant increase in the coefficient of filling with the material of the flexible casing, which will obviously lead to more significant damage to the material.
