MULTICOMPONENT VIBRATORY BATCHER OF LOOSE FEED

The design and the development of resource-saving machines and the technologies for the high quality bulk feed mixtures preparation directly in agricultural enterprises is one of the main tasks at present. Batching is a crucial process in the bulk mixture preparation since a high quality of the final product will not be achieved without the precise input of the components. High-precision dosing of loose components for obtaining a homogeneous mixture is a research and production problem. From the analysis of existing designs, a device of multicomponent vibratory batcher of loose feed is developed. It consists of a body in the form of wedge with sections. It is firmly mounted to the frame. Excitation system includes an eccentric vibration exciter with rods which have different eccentricities. Some activators are installed to avoid congestion of the material in each section of the batcher. Desired delivery of each section is set by the dampers placed vertically on the front wall of the batcher and moved along the guides whose position determines the layer thickness of the material dosed. The material within each batcher section is provided in a state of “fluidization” which enables to obtain a uniform outflow by reducing the fric- tion force. The aim of research is to increase the efficiency of dry feed mixtures and compound feed dispensing directly in agricultural enterprises. As a result the determining qualitative and quantitative indicators have been chosen as follows: the number of sections is 5, the width of the outlet is b = 0.1 m, the number of activators in the form of cylindrical springs is k = 25 pc, the oscillation amplitude of the batcher is A = 0.001…0.003 m, the angular frequency of the batcher oscillation is ω = 270…300 s-1, the slope of the batcher bottom is α = 45°, the filling ratio is ψ = 0.8. We have obtained the formulas of velocity determination of loose feed and the efficiency of the proposed dispenser.
