SUBSTANCE: invention relates to coulters for planting seeds and fertilizers in relation to no-till crop production technologies. The anchor opener 1 for the seeder for zero technology comprises a wedge-shaped part 2, a chisel 3, a stand 4, a seed tube 5 and a metal guide pipe 6. The wedge-shaped part 2 and the chisel 3 are made integral with the stand 4 and are located in the lower part of the latter. A hard alloy plate 7 with a sharp point of 65-67 is fixed on the surface of the chisel 3° , and the lower edge of the wedge-shaped part 2 is bevelled at an angleε = 5-8° down to the horizon. There is a protective casing 8 installed behind the guide metal pipe 6, which is curved along the contour of the rear part of the rack 4, made in the shape of a half ring. The lower edge of the latter is inclined towards the bottom of the groove, and the posterior peripheral part of the semiring has an oval window. There is a fixing ring 10 fixed in the lower part of the rack 4 and fastening plates 9 attached to the guide metal pipe 6 of the seed tube 5, providing the ability to quickly fix the seed tube 5 on the rack 4 during installation and dismantling of the anchor opener.

EFFECT: reduction in the energy intensity of the seed sowing process, the possibility of obtaining a smooth compacted surface of the bottom of the furrow, a uniform seed planting depth, and obtaining a uniform surface relief of the seed covering surface.
