FIELD: agricultural engineering, in particular, equipment for sowing of seeds and application of fertilizer.
SUBSTANCE: drill has frame, storage hopper and shanks. Seeds and fertilizers contained in storage hopper are fed in regulated amounts to shanks through dosing devices. Seed application shanks are made in the form of chisel-shaped shanks. Deepening guiding rolls are positioned rearward of chisel-shaped shanks. Shanks are arranged in several transverse rows one behind another and in spaced relation with respect to one another, transverse to direction of advancement. Disk shanks are positioned in at least one transverse row, rearward of chisel-shaped shanks. Shanks are spaced from one another by distance equal to doubled distance between chisel-shaped shanks. Drill of such construction allows seeds and fertilizers to be sown with insignificant soil movement and with the help of simplified means.
EFFECT: increased efficiency and simplified construction of drill.
