DEVICE FOR PRE-SOWING TREATMENT Russian patent published in 2016 - IPC A01C1/00 

FIELD: agriculture; engineering.

SUBSTANCE: device for pre-sowing treatment includes working body, drive mechanism, hopper, the unloading chute, drum sander, the inner surface is coated with a layer of rubber. Working body is made of unrelated rods, rollers, each of which is made of at least one strip folded along straight lines, disposed at an angle to the edges of the strips to form identical parallelograms, situated on the strip alternatively in opposite directions. When the strip is folded into cylindrical coils, connected to each other along the longitudinal edges to form on the outer surface of the polygonal unidirectional helical lines, and on the inner surface - polygonal screw pockets triangular shape. And each of the pivot-rollers covered with a layer of rubber and is provided on both sides of pins that have the ability to roll on copiers, mounted inside the grinding drum and the diameter of pins greater than the maximum diameter of the rod-roller that provides a constant gap between the rods, rollers and the walls of the grinding drum which is greater than the maximum size of the seed.

EFFECT: this device is simplified design allows you to expand its technological capabilities and improve productivity.
