Abstract

The invention relates to agricultural machinery, in particular, to seeders for ridge sowing of row crops. The ridge seeder includes ridge formers mounted on the frame, sowing machines and packer rollers. The ridge formers are made in the form of lancet paws with tacking feathers fixed to the frame in a checkerboard pattern. The packer rollers are located behind the lancet paws. The tipping feathers of each pair of lancet paws are directed towards the line of sown seeds at the same angle to the direction of movement of the ridge seeder. The longitudinal axis of symmetry of the packer rollers coincides with the line of sown seeds. Such a design of the ridge seeder will improve the quality of sowing of row crops, as well as the formation of ridges of soil over sown seeds with a given density of agricultural requirements.

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 perform in the form of lancet paws with tacking feathers, mounted on the frame in a checkerboard pattern. The packer rollers are positioned behind the lancet paws so that the longitudinal axis of symmetry of the packer rollers coincides with the line of sown seeds. Tailing feathers of each pair of lancet paws are directed towards the line of sown seeds at the same angle to the direction of movement of the ridge seeder.

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 machines 2 and packer rollers 3. On the frame 1, comb generators made in the form of lancet paws 4 with tacking feathers 5 are mounted in a checkerboard pattern. Tacking feathers 5 of each pair of lancet paws 4 are directed towards the line of sown seeds under the same angle to the direction of movement of the comb drill

The packer rollers 3 are mounted on the frame 1 of the seed drill by means of brackets 6. The longitudinal axis of symmetry of the packer rollers 3 coincides with the line of sown seeds.

The sowing apparatus 2 is connected by the vas deferens 7 with the opener legs 8 mounted on the frame 1.

The ridge seeder operates as follows. Previously, using the sowing apparatus 2 set the required rate of seeding. Set the required depth of seeding with the help of claws-openers 8, as well as the depth of the lancet paws 4 with tacking feathers 5.

With the movement of the sowing unit, the opener legs 8 and lancet legs 4 with tacking feathers 5 loosen the soil and cut the weeds. Sowing devices 2 through the seed tubes 7 direct the seeds to the claws-openers 8, which lay the seeds at the required 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. Packing rollers 3 compact the formed soil tubercle, finally forming the soil ridge.

The presence of lancet paws with tipping feathers mounted on a frame in a checkerboard pattern and setting the tacking feathers of each pair of lancet paws in the direction of the line of sowed seeds at the same angle to the direction of movement of the ridge seeder allows sowing seeds in the moist soil layer on a compacted bed, with the simultaneous formation of soil ridges over 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 located behind the lancet paws improves the quality of the formation of soil ridges above the sowed seeds, since the tubercle of the soil formed above the sowed seeds of the lancet paws with tipping feathers is compacted by the press rollers 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 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 at the same time germinate.
