摘要：
FIELD: agriculture.SUBSTANCE: agricultural sowing machine comprises the frame, the disc opener assembly with the first axis of rotation, the gauge wheel assembly with the second axis of rotation, and the packer wheel assembly with the third axis of rotation. The packer wheel assembly is made in the form of a furrow eradicator. The agricultural sowing machine frame is made in the form of a disc opener assembly housing. Wherein the gauge wheel assembly is connected to the disc opener assembly housing with the possibility of vertical adjustment by means of an additionally installed mechanism of vertical adjustment. The vertical adjustment mechanism is rigidly mounted on the disc opener assembly housing through a horizontal slab by means of studs and nuts. The vertical adjustment mechanism comprises a screw pair. The screw pair includes a rotating screw (an input link) and a rotating nut. The rotating nut is rigidly connected to the output link - a slider that forms a prismatic pair with racks. The rotating screw axis is arranged vertically and lies in the vertical longitudinal symmetry plane of the disc opener assembly. The rotating screw axis is arranged in front of the first axis of rotation relative to the sowing direction. A steering wheel is rigidly installed in the upper part of the rotating screw. Bushings are rigidly mounted on the free ends of the progressive pair racks. Axles are rigidly mounted in the bushings. A pair of gauge-wheels is mounted on the axles via bearings mounted in the housing. The pair of gauge-wheels has the inner side formed as a bowl. The pair of gauge-wheels with the inner side formed as a bowl is adjacent to the outer side of the pair of ploughshares of the disc opener. The second rotation axis of the pair of gauge-wheels is arranged in front of the first rotationl axis relative to the direction of sowing. The seed duct has the seed drop edge on its bottom part. The seed drop edge and the middle of the contact area of the gauge-wheels w
