REEL DRILL MACHINE Russian patent published in 2024 - IPC A01C7/12 

FIELD: agricultural engineering.

SUBSTANCE: precision drill machines. The reel drill machine contains a housing with an open upper surface for loading seeds, two end and two side walls with through holes for placing a horizontal shaft in them, connected to the drive. A coupling, a grooved coil and a shank are installed on the shaft, one end of which is installed in the hole of the coupling. The grooved reel is equipped with a removable bushing with rows of cone-shaped recesses aon its surface, a limiter to prevent seeds from spilling to the bottom of the housing, and an additional limiter for regulating the seed sowing rate. In this case, the limiter from spilling seeds to the bottom of the housing consists of an arcuate plate, a frame and a bracket connecting the arcuate plate to the frame. The limiter frame is located on the surface of the housing, and the arcuate plate is located under the removable bushing. An additional limiter for regulating seed sowing is made in the form of a plate with a rectangular cutout in its upper part and with a protrusion in the form of a plane, the shape of which is similar to the lateral inner surface of the housing. The protrusion is located relative to the plate at an angle of 90° and is located between the limiter bracket, the arc part of the removable bushing and the end wall of the housing.

EFFECT: sowing of small seeds and increasing the efficiency of sowing seeds due to their uniform distribution across the field.
