FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to working bodies for planting crops of tilled crops.

The opener opener is known, in which, in order to reduce soil loading in front of the opener and to seal the bottom of the furrow, the maral is made with a semicircular shape that is variable in length in front, the transition w, in the middle part to the pointed one and ends with a trapezoid 1.

However, the variable shape of its length in the zone of the formation of the furrow contributes to the active mixing of the soil, and hence the desiccation.

Most modern foreign crops are equipped with coulters of the arms of the type consisting of a wedge-shaped plate with sidewalls and a cutting part of the bed former and cheeks. Such a coulter becomes variable in the design of the wide distribution of Exakt-S-FRG beetroot.

The double-sided wedge of such an arm ensures the formation of a furrow with a uniform (on each side) emission

soil and wall compaction, as well as cutting plant residues 2.

However, when using such coulters with a double-sided symmetric wedge in high humidity conditions, the cheeks of the coulters appear sticking, especially on the spikes with high-speed sowing machines, which have a long seed ejection path and, therefore, the coulter cheeks are elongated; The crop residues are not cut by the maral, but due to the symmetrical distribution of forces on both sides of the wedge, they are not removed from it, but they are unloaded on it, contributing to sticking and clogging.

The purpose of the invention is to prevent

15 sticking and clogging of the maral plant with plant residues when working on soils of high humidity and reducing soil desiccation in the furrow zone.

This goal is achieved by the fact that the 20 cutting part of the tip is made in the form of a one-sided clamp, the point of which, when moving from the straight sidewall of the tip to the center of the bed former, has a curvilinear surface.

The opener cheeks are made different in length, with a short cheek located on the side of the straight sidewall of the tip.

FIG. 1 shows the proposed opener, side view (in working position); in fig. 2 - 5 - sections A-A, BB, B-B, GG in FIG. 1 of the furrow formation zone along the radius 7 parallel to the day surface, the passage of sh. I along the line MN); in fig. 6 is a view along arrow D in FIG. 1, in FIG. 7 is a view along arrow E of FIG. 1 (rezhush transition, the part of the one-sided wedge in FIG. 8 is the shape of the furrow obtained after the passage of the coulter.

An opener opener (Fig. 1 and 7) includes an opener 1, where the right sidewall 2 of it is designed as a flat surface parallel to the axis of the row, to which the frontal surface 3 is located at an acute angle, thus forming a one-sided wedge 4 Part 5, the tip of which gradually passes along the curved surface 6 in the furrow formation zone bounded by a plane parallel to the ground surface of the soil passing along the MN line to the center of the forger 7 and the two cheeks of the soschnik: the right 8 and the left 9.

Nalilnik works as follows.

In the working position (Fig. 1), upon contact with the soil, the tip opens the furrow 10 (Fig. 8). Seeds 11 are placed in the open furrow. With its further movement from the side of the elongated cheek joint, soil particles are self-drenching into the furrow 10, covering the seeds with a layer of a certain thickness.

The short cheek of the opener, which is a continuation of the right side of the neck 1, forms a compacted vertical wall 12 of the furrow, which prevents it from self-shedding. Due to the different lengths, the cheeks are shortened. zone of possible sticking of the joint on the soils of high humidity.

The cutting part 5 of the tip 1 is strung with plant residues 13, which are affected by the total soil response R. The component of this reaction, R;, directed along the frontal surface 3, tightens the plant residues 13, as well as the stuck soil from the opener blade.

The transition of the edge of the wedge along the curved surface 6 in the zone of formation of the bottom of the furrow, bounded by the plane MN, to the center of the bed-former 7, prevents plant residues from peeling on it and ensures their contraction from the base of the joint.

The working process of the proposed joint of the open joint is characterized by the formation of a groove, in which one of the lateral

The walls are loosened, and the second is compacted, i.e. there is no mixing of soil particles, and, consequently, the elimination of it.

The use of the proposed device on existing and projected forgings will allow increasing field germination of seeds, their uniform embedment depth by preventing sticking and clogging by plant residues of the base of the joint, reducing depletion

the soil in the furrow zone, and cheeks of different sizes along the length ensure its operation on soils with increased humidity.
