PLANT FOR GRINDING SEEDS Russian patent published in 2016 - IPC A01C1/00 

FIELD: agriculture; engineering.

SUBSTANCE: installation for grinding seeds contains grinding drum unloading window, working body, hopper, the unloading chute. Inside the container is mounted coil spring equipped with a device for changing the pitch of turns by stretching or compressing it. Grinding drum is designed as a container, resiliently mounted on the base with a vibrator, and is made from at least one strip folded into cylindrical coils, connected to each other along the longitudinal edges folded on placed at an angle to its edges along fold lines with forming on the outer and inner surfaces directed towards one helical screw lines and surfaces in the form of pockets of a polygonal shape. Distance between the fold lines is equal to the length of each polygon element. Inner surface of the container is covered with a layer of rubber inside the container and fixedly mounted spring waveform with a circular cross section and a direction of turns of coils opposite to the direction of helical surfaces and the helical lines of the container.

EFFECT: invention extends the technological capabilities and improves performance.
