DEVICE FOR GRINDING SEEDS Russian patent published in 2019 - IPC A01C1/00 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, in particular to equipment for pre-sowing treatment of seed material, and can be used for preparation for sowing of small-seeded crops. Device comprises an unloading tray, a metering hopper and a grinding drum with an unloading opening made in the form of a container with an inner surface coated with a rubber layer. Device is elastically installed on base with vibrator. Container is made of sections mounted from two subsets identical in size and shape, made in the form of hollow four- and more coal prisms. Prisms bases are turned relative to each other along central axis 0₁-0₁ subsection by angle of up to 45° with formation along the perimeter of hollow subsections of four or more rectilinear lines, four and more internal helical grooves and four and more smooth curvilinear surfaces of one direction. Forming bases of four- and more carbon forms of each subsequent hollow subsection are turned relative to previous hollow subsection along section axis by angle of up to 45° with formation of four and more broken screw lines along section perimeter, along its entire length and along entire length of container, four and more broken internal helical grooves and four and more broken curvilinear surfaces of one direction.

EFFECT: use of the invention will make it possible to expand technological capabilities of the device for grinding seeds.
