Description

The invention relates to agricultural machinery, in particular to seeders for ridge sowing of row crops.

Known ridge seeder [1], including ridge formers mounted on the frame, sowing devices in the form of hollow drums with plunger ejectors of seeds installed inside them, rolling rollers and disk earthing. The sowing units are located inside the packer rollers. The packer rollers have an elastic outer rim, and plunger ejectors of seeds are connected with an elastic outer rim.

However, the known device has several disadvantages, which include:

- unsatisfactory quality of sowing of row crops;

- low quality of the formed ridges of the soil.

The purpose of the invention is to improve the quality of sowing and the formation of ridges of soil over sown seeds.

This goal is achieved by the fact that ridge formers containing lancet paw, stand, bracket with adjusting plate, L-shaped bracket with half shaft and blade are fixed to the frame in a checkerboard pattern. The blade is made in the form of a spherical disk and is mounted on the semi-axis with the convex side to the L-shaped bracket with the possibility of changing its height position along the strut and changing the angle of attack of the spherical disk in the horizontal plane, as well as fixing it in a given position. Packer rollers containing a frame, spherical discs, packer rings, an axle, a rod with a spring, are arranged behind the ridge formers with the possibility of regulating the pressure on the soil. The spherical disks of each pair of combing machines are set symmetrically relative to the line of sown seeds at an acute angle, the solution of which is directed along the ridge seeder, and the longitudinal axis of symmetry of the packer rollers coincide with the line of sown seeds.

Figure 1 shows the ridge seeder, side view, figure 2 is the same, a top view, figure 3 is a comb, top view, figure 4 is a section of the comb forger along the line AA.

The ridge seeder contains a frame 1, sowing machines 2 and rolling rollers 3. On the frame 1, ridge formers are fixed in a checkerboard pattern 4. The ridge formers 4 contain a pointed arm 5, a stand 6, an arm 7 with an adjustment plate 8, an L-shaped bracket 9 with a half shaft 10 and blade 11. Holes 12 are made on the adjusting plate 8. The L-shaped bracket 9 is mounted on the adjusting plate 8 and secured by bolts 13 and 14 with nuts 15 inserted into the holes 12. The blade 11 is made in the form of a spherical disk. A cylindrical body 16 with a bearing 17 is mounted on the blade 11. The blade 11, by means of the bearing 17, is mounted on the axle shaft 10 with the convex side to the L-shaped bracket 9 with the possibility of changing its height position along the rack 6 and changing the angle of attack of the spherical disk in the horizontal plane, as well as fixing it in a given position. The necessary position of the spherical disk 11 in height along the strut 6 is set by moving the axle shaft 10 together with the spherical disk 11 in the groove 18, made in the vertical part of the L-shaped bracket 9, and fixed in the desired position by means of the nut 19. The desired angle of attack of the blade 11 is set by rotation G -shaped bracket 9 together with the axle shaft 10 and the spherical disk 11 around the bolt 13 and are fixed in the required position by a bolt 14 inserted into the holes 12. The spherical disks 11 of each pair of comb formers 4 are mounted symmetrically o relative to the line of sown seeds at the same acute angle, the solution of which is directed along the direction of the ridge seeder.

The packer rollers 3 on the frame 1 of the ridge seeder are fixed by means of brackets 20 and are located behind the comb generators 4. The packer rollers 3 contain a frame 21, spherical discs 22, packer rings 23. Spherical discs 22 and packer rings 23 are mounted on the axis 24 with the possibility of rotation. The press rollers 3 also comprise a rod 25 with a spring 26. By means of the spring 26, the pressure of the press roller 3 on the soil is regulated. The longitudinal axis of symmetry of the packer rollers 3 coincide with the line of sown seeds.

The sowing apparatus 2 is connected by the vas deferens 27 with the opener legs 28 mounted on the frame 1.

The ridge seeder operates as follows. Preliminarily using the sowing apparatus 2 set the required seeding rate. Set the required seed placement depth using the opener paws 28, as well as the depth of the ridge formers 4 with spherical discs 11. By compressing the spring 26, the required roller pressure is set to the soil.

When the sowing unit moves, the coulters 28 and comb 4 with spherical discs 11 loosen the soil, weeds are cut. The sowing apparatus 2 through the seed tubes 27 direct the seeds to the claws-openers 28, which lay the seeds to the desired depth. Coming ridge formers 4 with spherical disks 11 sprinkle the seeds with a loose and warmed layer of soil, shifted from the row-spacing, thereby forming a tubercle of the soil above the sown seeds. Press rollers 3 compact the formed soil tubercle. Spherical disks 22 mounted on the convex side to the axis of symmetry of the packer roller 3 for more uniform soil compaction, together with the packer rings 23 and due to the pressure of the spring 26 form a ridge of soil, compacting it on three sides. At the same time, the packing rings 23 compact the top of the soil tubercle, and the spherical disks 22 are the lateral sides of the soil tubercle and finally form the soil ridge.

The implementation of ridge formers 4 in the form of lancet paws 5 with spherical disks 11 mounted on a frame in a checkerboard pattern, and the installation of spherical disks 11 of each pair of ridge formers 4 symmetrically with respect to the line of sown seeds at the same acute angle, the solution of which is directed along the ridge seeder, allow sowing seeds into the moist soil layer on a compacted bed, with the simultaneous formation of soil ridges above the sown seeds. This improves the quality of sowing and improves the temperature, water and air conditions for the development of plants.

The presence of press rollers 3 located behind the ridge formers 4 with the possibility of regulating the pressure on the soil, containing a frame 21, spherical disks 22, press rings 23, an axis 24, a rod 25 with a spring 26, improves the quality of the formation of soil ridges above sown seeds, since it is formed above sown seeds by seeds with combing agents 4, the tubercle of the soil is compacted by rolling rollers 3 on three sides with the necessary pressure. This helps maintain the shape of the finally formed soil ridges throughout the growing season. The location of the packer rollers 3 along the line of sown seeds allows you to form ridges above the sown seeds, while the seeds lie exactly at a given depth and simultaneously germinate.
