CLASSIFIER OF STEM FODDER Russian patent published in 2014 - IPC A01D82/00 A23N17/00 

FIELD: agriculture.

SUBSTANCE: classifier comprises a housing provided with rollers mounted on guides, a set of screens of trapezoidal cross-section in which lower bases rectangular holes are provided, obliquely mounted trapezoidal trays, chute boards, containers for collecting fractionated stem fodder, traction, and drive. The classifier is also provided with two electric motors and a motor control system. The input of the system is connected to a three-phase alternating current network. The electric motors make linear progressive motion and are made in the form of three-phase linear asynchronous motors, at that the secondary element of the motors is the thrust, rigidly connected to the housing and located on the side of the drive. Winding of the three-phase linear asynchronous motors is connected to the output of the motor control system.

EFFECT: improved technical and economic indicators.
