PLANTING UNIT Russian patent published in 2016 - IPC A01C7/12 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agricultural engineering, in particular to sowing devices for precision sowing crops with simultaneous application of mineral fertilizers. In addition, it can be used as a metering device for bulk materials in other sectors of national economy. The planting unit comprises a seed wheel 3 with grooves for seeds and a brush seed reflector 4, mounted in the housing with the ability of rotation. Inside the housing a partition is mounted, for separation of the seeds and fertilisers 18. The lower part of the housing a window is made for feeding into it of mineral fertilisers by the brush seed reflector 4, and the dispenser of seeds with cells separated by the partitions is mounted. The seed wheel 3 is fixedly secured to the driving shaft 11, and the brush reflector 4 - on the drive shaft 12 on which the drive sprocket 5 is mounted. The latter drives the drive 12 and the driving shafts 11 in a one-way rotation through the additional sprockets 6 and 7 mounted on them, interconnected by the chain drive.

EFFECT: invention enables to implement the simultaneous sowing seeds and fertilisers, to improve the reliability of seeding by avoiding damage and missing seeds and metering accuracy with a predetermined amount of seeds on the surface of the bed prepared in the soil.
