FIELD: agriculture.SUBSTANCE: opener section of the seeding machine comprises a freely rotating flanged flat blade mounted on a leash, a seed-guide and a furrow-generating working body mounted fixedly. The furrow-generating working body has a front pointed part connected along the radius of a circle between the vertical part and the lower horizontal part. The angle of tapering of the jaws of the furrow-generating working body is made smaller than the angle of friction of soil to steel. The seed-guide is coupled with the rear part of the furrow-generating working body, is made with variable cross section and has a tapering in the lower part which width is equal to the width of the furrow formed by the furrow-generating working body. The seed-guide front wall has a greater length than the rear, that forms the point of the seed-guide. Behind the seed-guide on the height-adjustable rack, made fork-shaped, a compacting-embedding roller is mounted, in the form of two truncated cones opposite mounted with the smaller sides. The roller width is greater than the width of the furrow. Behind the compacting-embedding roller using the traction a mulching coverer is mounted in the form of a mesh harrow. The opener section is mounted on the beam having parallelogram hinge weighed on the frame of the seeding machine.EFFECT: invention enables to improve the seed germination and yield.1 dwg |
