FIELD: agriculture.
SUBSTANCE: invention relates to agricultural machinery industry and can be used in machines for harvesting grain and grain legume crops. The device comprises passive stem distributors, belt conveyors with a drive and a hollow beam-air circuit mounted on the running wheels. The belt conveyors are located in the longitudinal-vertical plane on horns attached in cantilever fashion to the hollow beam-air circuit. Between the adjacent conveyors there is a chamber in the form of a rectangular parallelepiped, which one wall has a louvered surface and is made up of individual fixed vertical planks. On each conveyor belt the whips are placed, which together with the chamber planks form the threshing machine. The threshed grain is sucked through the louvered surface into the chamber and through the hollow beam-air circuit is sent to the storage hopper.
EFFECT: device provides reduced losses of grain when threshing at the grassroots.
