Analysis of Vibrating Feeders for Transporting and Dosing Seeds in the System of Their Automatic Phenotyping

The paper presents the actualization of the use of vibrating feeders in modern technological lines for processing and preparing seeds of agricultural crops. The results of scientific research into the process of transporting and dosing particles of loose cargo along the working body of the vibrating feeder are presented. The dependence of the qualitative characteristics of the operation of vibrating feeders on the influence of such parameters as the granulometric composition of cargo particles, the height of the transported cargo layer, the inclination of the working trough of the feeder bowl to the horizon, the angle of inclination of the disturbing force vector, the trajectory of movement of the working body of the vibrating feeder, etc. is described. An analysis of existing designs of bunker spiral vibrating feeders is presented. Analysis of the designs of vibrating feeders has shown that an electromagnetic vibratory drive is most often used as a vibratory drive of feeders. The elastic elements of vibrating feeders are polymer or metal springs in the form of rods or plates inclined at an angle to the horizon. The elastic suspension of the feeder hopper in the form of a hyperboloid torsion is also widespread. The current direction of development of designs of vibrating spiral feeders is to ensure oscillation of the working body along an elliptical trajectory. This can be achieved by the following methods: creating a special design of the elastic elements of the vibrating feeder, placing the vibration drives relative to the working body, using vibration drives that can change the trajectory of movement of the working body from linear to elliptical. The material made it possible to systematize achievements in the development of designs and ways to increase the efficiency of using vibrating feeders for transporting and dosing seeds of agricultural crops.
