FIELD: agriculture. ^ SUBSTANCE: opener has a rack and two cheeks with the seal of the furrow bottom. Two vertical slots are made in the rack. Forepart of the opener rack in the plan is V-shaped. The rack on both sides has symmetrical knives with sharpening. The knives are set at angles to the horizon in the longitudinal and transverse planes with the ability to move through the slots of the rack. Furrow plows are mounted on the knives with the ability to move along two rows of holes. In the latter, vertical drill tubes are located, passing into the seals drill tubes of the bottom of the lateral furrows, which end as the horizontal slot in the lower part. Over the furrow plows, the plate-struts with holes are located. The furrow plows are fixed on the knives with the seals rods, passing through the knives, furrow plows and the plate-struts. The rods in their upper part have a threaded end where retaining nuts are mounted. On the underside the seals and furrow plows are connected with screws. The seals have a parallelepiped shape rounded at the sides. ^ EFFECT: invention enables to provide simultaneous multi-component sowing of crops in parallel furrows to the depth and width of row spacing defined by agronomic requirements. ^ 5 dwg |
