SHARE Russian patent published in 2000 - IPC

FIELD: agricultural engineering. SUBSTANCE: share has body 1 with single involute cutting edge 2 sharpened at an angle of β ≤ ϕ, where ϕ is angle of friction of stubble and soil remains relative to steel (ϕ=27-20 deg). Share is further provided with two cheeks 3 rigidly attached at body sides, conical branch pipe 6 rigidly connected to cheeks 3, seed guide 7 inserted into branch pipe 6, depth limiting device 10, tie-rod 12, and pressing spring 13. Cutter-type share may be used for sowing of cereal, legume and other crops. Such construction of share facilitates uniform distribution of seeds in soil, improved contacting of seeds with soil and, consequently, intensified germination of seeds. EFFECT: increased efficiency, enhanced reliability in operation, improved seed yield and increased quality of product. 4 dwg
