FIELD: agriculture.

SUBSTANCE: granular materials thrower contains clamping blade (1), leading (2) and driven (3) drums, an endless belt (4) mounted on them. In the central part of the blade drum (1), along its inner circumference, a receiving-feeding device is installed in the form of a receiving cylinder (5) with an outlet window. The lower edge of the cylinder (5) outlet window is located at the point (C) of circle intersection with the vertical diameter of the drum or opposite the point of contact of the drum circumference with the belt. The upper edge of the cylinder (5) outlet window is located at point (D) above the drum horizontal diameter by 10°. In the receiving cylinder (5), there is a receiving auger (6) connected to the feed hopper (7) and radial feed blades (8) located around the auger (6). The clamping blade drum (1) is made of two ends and one intermediate ring disks installed parallel to each other. Between the end and intermediate ring disks, there are two rows of inclined blades (11) having a cross-section in the form of a versatile triangle with vertex directed to the center of the drum (1) and lies on the inner circumference of the drum, and its base extends along the outer circumference of the drum (1). When the blades (11) bases touch the belt (4), cells (12) form between the blades (11).
