The article presents the results of experimental studies of the design spiral vibrating feeder, which will be used for dosing single sunflower seeds in an automated phenotyping line. The data on the methods of design and planning of experimental studies of cup vibrating feeders are presented in detail. The results of the analysis and systematization of the main factors affecting the process of vibration movement of sunflower seeds along the trough of the vibrating feeder are presented. Using additive FDM technology, an experimental sample of a vibrating cup vibrating feeder was manufactured by 3D printing. The structure of the experimental setup for studying the amplitude-frequency characteristics (AFC) of the experimental vibrating feeder is described. To study the influence of the mass of sunflower seeds contained in the bowl of the vibrating feeder on the change in its amplitude-frequency characteristics, seed samples weighing 29 g, 58 g and 116 g were prepared. Also, in order to determine the nature of the vibration movement of seeds, batches of seed samples with different size groups were formed. The results of the research are presented in the form of graphical dependences of the change in the vertical amplitude, vibration velocity and vibration acceleration of the bowl of the designed spiral vibrating feeder, depending on the circular frequency of forced oscillations created by the unbalanced vibration drive. The experimental frequency response is displayed depending on the mass of sunflower seeds loaded into the bowl of the vibrating feeder. The optimal transportation speed, when dosing sunflower seeds, was obtained at the values of forced circular frequencies ω in the range of 150-170 s-1, at the values of vertical amplitudes of oscillations of the bowl A of 0.35-0.6 mm. Such vibration parameters are obtained at a supply voltage of the vibration motor of 3.3 V. In all variants of loading the bowl of the vibration feeder, the movement of the seeds was characterized as inseparable from the surface of the chute. A factorial experiment established second-order regression equations indicating the dependence of the optimization parameters: vertical amplitude of oscillations A, mm of the bowl of the vibration feeder, vertical vibration velocity V, mm/s and vibration acceleration a, m/s2 on the following independent factors: mass of seeds loaded into the bowl m, g and supply voltage of the vibration motor U, V.
