Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, for horizontal line seeding.

The purpose of the invention is to increase the uniformity of distribution of seeds across the lines, regardless of the angle of inclination of the sowing unit.

FIG. 1 is a side view of a sowing belt for line seeding; in fig. 2 the same, top view; in fig. 3 - mixer; in fig. 4 — sowing coulter, cross section; in fig. 5 is a section A-A in FIG. four; in fig. 6 - opener, top view; in fig. 7 is a section BB in FIG. four.

The horizontal row sowing plant contains frame 1 mounted on support wheels 2. Seed phik 3 is installed on the frame with seeding devices 4. The drive is sown, their devices are made from field wheels 2 through a chain drive 5. To frame 1 with the help of a four-bearing hinge 6 sections 8 are attached with a spring 7. Each section has a supporting corment wheel 9 designed to set the seed embedment depth. Each section has three coulters 10 and 11 secured, and the coulters are arranged in a checkerboard pattern (Fig. 2). On frame 1, a source 12 of compressed air is installed with a drive from the tractor's power take-off shaft through a cardan drive 13 or with the help of a hydraulic engine. In addition, an air distribution pipe 14 is installed on the frame of the cutter. Each plant is sown, and the device has installed mixers 15. Air duct 16 compressed air source 12 is connected with air distribution pipe 14. Air ducts 17 mixers 15 are connected to pipe 14. Mixers 1.5 communicate with sowing openers 10 and 11 using flexible transparent sem wires 18. Structurally, the mixers are made in the form of a cylindrical chamber 19 with a transitional conical part 20 (Fig. 3), ending with a flange 21 on which this wire is worn d 18. In the cylindrical chamber of the mixer pipe 22 is installed, communicating with a compressed air source 12. Natrubok 22 is mounted at an angle less than 90 ° to the vertical and, in addition, is located at a tangent to the inner surface of the cylindrical chamber 19.

The opener is made with a hollow stand 23 (Fig. 4), inside which a stabilizer 24 is installed to increase the uniformity of seed distribution over the cross section of the throughput hole, made in the form of a conical cylindrical sleeve facing upwardly extending upwardly with a plate placed under it in the longitudinal-vertical plane 25 (FIG. 6) serving to separate the air-seed mixture

on two equal flow. In the front and rear parts of the rack, stiffening ribs 26 are installed. The rack 23 passes into a wedge-shaped opener 27. Inside the opener, using a screw 28 (Fig. 5), a seed distributor 29 is fixed in the form of channels, designed to distribute the air-seed mixture into four equal parts. Adjustable dampers 30 are installed inside the distributor 29 (Fig. 7), by means of which a uniform division of the air-seed mixture flow into four equal parts is achieved. The seal of the box 29 at the junction with the hollow stand 23 is made of a rubber ring 31 (Fig. 4).

2 The output tubes 32 of the junction box 29 are directed into spherical coulter chambers 33, which are transformed into triangular polosovid packers - furrows 34.

Selka works as follows.

0 When the sowing unit moves across the field with recessed coulters, the source of compressed air 12 supplies air to the distribution pipe 14, and then to the mixers 15. In the mixer, fed through an inclined

5, the tangential air, forming a rotational motion, creates a uniform air-seed mixture, which uniformly flows through this wire 18 to the coulters 10 and I. When the stabilizer 24 rises, the speed of the mixture increases and the mixture becomes more uniform and independent of the topography of the soil and internal surfaces of the wire. Plate 25 divides the flow of the mixture into two equal parts, which, falling into the distributor 29 seeds, are divided by

flap 30 into four equal parts. If it is necessary to adjust (this is done under stationary conditions), the area of the flow sections of each of the four channels of the junction box 29 is changed with the help of valves 30 fixed by screws (not shown).

Then, the air-seed mixture, falling into the spherical chambers 33, changes the direction of movement, the speed of the mixture drops sharply and the seeds with air come out through the triangular polosovid packers-furrows 34, to the soil. Moving on the soil, packers 34 are compacting it and causing moisture to rise to the seeds. The rotational movement of the airborne seminal s.messi ensures the supply of a homogeneous mass to the coulter, and therefore, uniform sowing is achieved, regardless of the topography of the soil, the state of the surfaces of these wires and coulters. A layer of soil, raised by a wedge-shaped vomer 27, uniformly falls asleep formed grooves filled with seeds.
