摘要：
FIELD: agriculture engineering.SUBSTANCE: machine for grinding seeds contain hopper, the unloading chute, in the form of a container grinding drum unloading window, inside which is mounted a spring-operated to change the pitch of it by stretching or compression. Container resiliently mounted to the base with the vibrator is formed as a multi-start helical surface with helical grooves inside and outside of the container at an angle of 15°-75° to its axis to form pockets curved with the centers of curvature of the curved pockets helical surface arranged alternately outside and within the cross section of the container assembled from one rolled into cylindrical coils, connected to each other along the longitudinal edges, strips of equal width, bent sinuously from placed at an angle to its longitudinal edges along fold lines to form at the outer and inner surfaces directed to one side at an angle 15°-75° to the axis of the container in the form of helical surfaces of the pockets of the curved shape along the outer and inner surfaces. Distance between the fold lines is equal to the sum of the lengths of the perimeters of the geometric shapes of pockets inner and outer surfaces, the container is rigidly mounted inside the barrel-shaped spring with a circular cross-section turns and windings direction opposite to the direction of helical surfaces and the helical lines of the container, covered with a layer of rubber.EFFECT: invention makes it possible to expand the technological capabilities and improve productivity.1 cl, 7 dwgИзобретение относится к области сельскохозяйственного машиностроения.
