Description

The utility model relates to agricultural engineering, 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 to the 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 utility model 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 are made in the form of lancet paws with tacking feathers, mounted on racks pivotally mounted on the seeder frame in a checkerboard pattern, and provided with a spring. One end of the spring is fixed to the planter frame, and the other end is from the lower front of the comb former. Packer rollers containing a frame, spherical discs, packer rings, an axle, a rod with a spring, are located behind the lancet paws.

In Fig.1 shows a ridge seeder, side view, in Fig.2 is the same, a top view.

The ridge seeder contains a frame 1, sowing units 2 and packer rollers 3. On the frame 1, ridge formers made in the form of pointed arms 4 with tacking feathers 5 are staggered.

The ridge formers are installed on the stands 6. The stands 6, in the upper part, are pivotally mounted on the frame 1 of the ridge seeder using the axis 7, and have the ability to deviate from the vertical position in the direction opposite to the direction of movement of the ridge seeder. A spring 8 is installed at the front of the comb generator. One end of the spring 8 is fixed to the frame 1 of the ridge seeder, and the other from the lower front of the rack 6 of the comb generator.

The press rollers 3 on the frame 1 of the flare seeder are fixed by means of brackets 9 and are located behind the pointed arms 4. The press rollers 3 contain a frame 10, spherical disks 11, press rings 12. The spherical disks 11 and press rings 12 are mounted on the axis 13 with the possibility of rotation. The press rollers 3 also comprise a bar 14 with a spring 15. By means of the spring 15, the pressure of the press roller 3 on the soil is regulated.

The sowing apparatus 2 is connected by the vas deferens 16 with the opener legs 17 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 depth of seeding with the help of claws-openers 17, the depth of the lancet paws 4, as well as the necessary pressure of the packer roller 3 on the soil.

With the movement of the ridge seeder, openers 17 and lancet feet 4 with tacking feathers 5 loosen the soil, weeds are cut. Sowing devices 2 through the seed tubes 16 direct the seeds to the opener legs 17, which lay the seeds to the desired depth. The lancet paws 4 that follow, with their tail feathers 5, sprinkle the seeds with a loose and warmed layer of soil, shifted from the row-spacing, thereby forming a tubercle of soil above the sown seeds. Press rollers 3 compact the formed soil tubercle. Spherical disks 11 mounted on the convex side to the axis of symmetry of the packer roller 3 for a more uniform soil compaction, together with the packer rings 12 and due to the pressure of the spring 15 form a ridge of soil, compacting it on three sides. In this case, the rolling rings 12 compact the top of the soil tubercle, and the spherical disks 11 are the lateral sides of the soil tubercle and finally form the soil ridge.

The presence of ridge formers, pivotally mounted on the seeder frame in a checkerboard pattern, allows you to form ridges of the soil of the required size above the sown seeds. The installation of a spring in front of the ridge formers allows them to deviate in the direction opposite to the direction of movement of the ridge seeder when an obstacle appears on the surface of the field, eliminating the breakage of the ridge formers.

The presence of press rollers located behind lancet paws containing a frame, spherical disks, press rings, an axle, a rod with a spring improves the quality of the formation of soil ridges above sowed seeds, since the tubercle of the soil formed above the seeded seeds with tacking feathers is compacted by press rollers on three sides with the necessary pressure, contributing to the preservation of the shape of the finally formed ridges of the soil throughout the growing season. This improves the quality of sowing and improves the temperature, water and air conditions for the development of plants.
