SEEDING APPARATUS Russian patent published in 2010 - IPC A01C7/12 

FIELD: agriculture.

SUBSTANCE: invention primarily relates to agricultural engineering but is to be additionally utilised in other industries for bulk materials dosage. The seeding apparatus is composed of a housing with an upper and a lower windows for bulk materials passage. In the upper window two curtains are attached with one end, fabricated of a resilient and elastic material. The lower ends of the curtains touch a reel mounted on a shaft. The shaft is fixed inside the housing. The seeding apparatus shaft is connected to the drive shaft, for example - that of a stepping motor. The drive is attached onto the seeding apparatus housing and connected to the control unit. The control unit, in its turn, is connected to the control panel and the speed sensor. On the reel both butt-ends there are guides rigidly attached shaped as discs or rings. The guides inside walls are profiled and inclined outwards at an angle of α=3-7°.

EFFECT: proposed seeding apparatus is noted for improved reliability and enables accuracy of seed dosage and operation stability.
