COMBINED SINGLE-DISK SHARE Russian patent published in 2005 - IPC

FIELD: agricultural engineering, in particular, equipment used in sowing machines.

SUBSTANCE: share has disk vertically mounted on bracket at an angle to direction of advancement of machine, said bracket providing alignment of draft direction with machine advancement direction. Disk is provided with restricting flange arranged on its outside and formed as semi-elliptical member of rotation attached to disk by means of detachable members. Covering devices are positioned between fertilizer guide and seed guide for covering of fertilizer and seeds with wet soil layer. Supporting-covering rollers provided in lower part of covering devices are adapted for covering of fertilizer and seeds with compacted soil layer in order to facilitate contacting of seeds and fertilizer with moisture necessary for growing and development of plants. Chain-type sweep disposed behind covering devices is adapted for creating mulching soil layer and moisture retention.

EFFECT: improved uniformity of advancement of share through soil depth, increased efficiency by combining fertilizer application procedure and seed sowing procedure, separation of seeds from fertilizer by compacted soil layer without carrying out lower soil layers onto surface and embracing share with plant remains.
