The invention relates to the agricultural industry, in particular, to the coulters seeders for sowing agricultural cultures. Disk anchor opener comprises a housing 1 with node 2 mounting it to a leash coulter bar drills, flat disk 3 is mounted at an angle to the direction of movement, anchor-lozheobrazovatel the outer 5 and inner 6 sidewalls semyatukonapravitel 7, valve 8, made in the form of expanded funnel, visor-reflector 9, earthing devices 10 with the spring 11 and a lead 12. pochvonapravitelyami invention is characterized in that the anchor-lozheobrazovatel equipped with removable partition-valve 13, designed as a spring bar bent, SET lennoy between its side walls 5 and 6 and attached to the bottom socket of the distributor 8 and the guide-stops 14 arranged at the bottom of the inner surfaces of sidewalls 5 and 6 of the anchor, the lower portion of the partition flap 13, parallel to the lower edges of the side walls 5 and 6 earthing devices 10 configured as a horizontally disposed arcuate braces which ends are rigidly fixed pochvonapraviteli 12 is attached to semyatukonapravitelyu 7 via an arm 15 with a vertical slot 11 for a lead wherein the leash 11 has a possibility of translational movement along the slot and is provided with vertical compression spring 16, pochvonapraviteli 12 are fixed at an angle α = 30 ° ... 50 ° to the direction of travel, the distance between their inner ends in the longitudinal direction L = 3 ... 10 cm, and width earthing devices arcuate bracket 10 does not exceed the distance between the axes of the coulter. Moreover, the inner cavity of the anchor-lozheobrazovatelya formed by the outer 5 and inner 6-sidewalls and the partition flap 13, the elastic material filled with a porous filler, such as "sealing foam" or polyurethane. The use of utility model will enhance the productivity of agricultural cultures due to qualitative and reliable operation of a processing band sowing. 1 SP f BACKGROUND ZP 1 f ly-2 Fig.Полезная модель относитс
