FIELD OF THE INVENTION The invention relates to agricultural machinery engineering, in particular, to openers for the subsoil of new-and-wide seeding.

The purpose of the invention is to increase the uniformity of the distribution of seeds across the width of the seeding strip.

Fig. „1 shows a opener for random seeding, side view; in FIG. 2, section A-A in FIG. 1; in FIG. 3, view B in FIG. 1.

The opener for broad sowing contains a hollow stand 1, an extrusion of a torn paw 2, an edge 3 of the chamber 4 of the seed distribution. In the latter there are 5 longitudinal and transverse

I 6 trays, and the bottom of the tray b is made I but in the form of a lattice 7 with a rectangular

holes 8, the width of which increases as i moves away from the axis; howl line opener. 3 camera cover

 to the horizon and provides a slip and a uniform distribution of seeds across the entire ishrine of the sown strip. The transverse trays 6 have side walls 26 with flanges 27, by means of which the trays are fastened with bolts 10 to the roof 3 of the distribution chamber.

The opener for broad sowing works in the following way.

The grain jet moving with the stand 1 during the operation of the cutter in the lower part of the stand 1 is guided by a longitudinal tray 5f overlapping the entire cross-sectional area of the stand 1 to the transverse tray 6, the bottom of which is made in the form of a lattice with rectangular openings whose width proportional to the distance from the opener center line. The grain jet slides along the grate bottom of the transverse tray to both sides of the coulter center line, which is provided by tilting

The j fastener uses a flange of 11.25 bottom to the horizon and is evenly redirected downwards, which ensures that the lid and paw legs are flush to fit, In the middle part of the roof, it is fastened to the rack-and-wire with screw 12 through the eye 13 3 has an elastic flap 14 directed downward (the latter simultaneously performs the function of the rear wall of transverse trays 6). The flap 14 has a lower edge 15 (FIG. 3) located above the bottom of the furrow at a height of 8-10 mm, which ensures the absence of a scuffing. The elasticity of the seeker ensures self-cleaning from accidental contamination. The camshaft 3 of the distribution chamber 4 are provided with cut-outs 16 and 17 on the sides, the rear ends 18 of which are displaced to the axial line of the coupling, which helps to reduce the clogging of the internal cavity of the distribution chamber. 19, and in the middle part.- to 3. distribution chambers, bolts 20. For fastening, the side walls 21 of tray 5 are provided with flanges 22. In the rear part, starting from the transverse line 23 passing through the ends of the wings of the paw, the bottom 24 of tray 5 turns into wedge faces 25 that perform the functions bottom of cross trays 6. This bottom is made in the form of a lattice, nak0

made across the entire width of the seeding strip.

Increasing the uniformity of distribution across the width of the seeding strip provides a more complete utilization of the area of nutrition, which leads to an increase in the yield of grain crops.

Claims (2)

1. A sowing spreader containing an extirpal paw, a rack-and-seven wire, a closed sieving chamber and located between the front wall of the rack and the rear wall of the sieving chamber across its entire width, a diffuser tilted back along the movement, with the aim of increasing the uniformity of seed distribution across the width of the seeding strip; the diffuser is made in the form of a tray, the bottom of which in the rear part, starting from the transverse line passing through the ends of the wings of the paw, is made in the form of a dihedral wedge with an edge The driver has an axial line of the opener, and the angle of inclination of the faces to the horizon is not less than the angle of repose. 2. A collar according to claim 1, characterized in that the faces of the wedge are made in the form of grids with rectangular holes, the width of which increases as they move away from the opener center line. / 2 from ahhh dad
