FIELD: agriculture.
SUBSTANCE: invention relates to agricultural machines for feed preparation. The measurer comprises a frame, a discharge trough with an adjusting valve, a collecting hopper mounted on it on the fixed support. The discharge trough is driven to oscillating motion by three-phase linear asynchronous motor. The secondary element of the three-phase linear asynchronous motor is a spring-loaded rod rigidly connected to the discharge trough and located on the drive side. One winding of the three-phase linear asynchronous motor is connected to the AC mains, and the other two are connected in series and are connected to the output of the single-phase frequency converter which input is connected to the AC mains.
EFFECT: use of the invention enables to improve reliability and performance of operation of the trough vibration measurer of granular feed.
