摘要：
The invention relates to agricultural engineering and can be used in sowing machines. A combined coulter consists of a runner-type part, which is formed by certain units connected in series, in particular a knife-like coulter point, a furrow plough and cheeks, and of an A-type flat hoe part, which is mounted behind the cheeks of the coulter. The A-type flat hoe part is mounted above the level of the bottom of the furrow plough in such a manner as to allow adjusting for height and additionally equipped with two coverers. In doing so two cheeks are made as those symmetrical, in such a manner as to allow free fall of seeds at the site of attachment thereof from the seed sowing unit, which is mounted above the runner-type part. Also, additionally, between the blades of the A-type flat hoe part mounted is a sprayer unit, comprising a slit direct-flow sprayer, which is oriented backwards and directed to the plane of the cutting of the blades of the A-type flat hoe part of the coulter at an acute angle, and the coverers are oriented forward and arranged under the working surfaces of the blades behind the apex angle, which is formed by the A-type flat hoe part, and between the cutting edges of the blades. Furthermore, the design of the coverers or arrangement thereof is asymmetrical, where front parts thereof are oriented forward and spaced in horizontal plane wider than the rear parts of the coverers from the axis, which coincides with the axis of the body of the sprayer unit, so that the place of leakage of the working liquid from the sprayer unit is arranged between the rear edges of the both coverers, which at that are arranged in the vertical plane below the axis of the body of the sprayer unit. Thus, it is namely the agreed arrangement of the coverers and the sprayer enables to achieve the objectives regarding the quality strip subsurface application of working liquids, in particular herbicides, simultaneously with sowing.Изобретение относится к сельскохозяйственному
