Abstract

FIELD: agriculture.

SUBSTANCE: bedder planter comprises ridge formers, sowing units and rollers fixed on the frame. Ridgers are fixed on the frame in a staggered order and comprise a centre hoe, a stand, a bracket with an adjustment plate, a L-shaped bracket with an axle and a leaning disc. The L-shaped bracket is installed on the adjustment plate. The leaning disc is fixed on the axle as capable of rotation around its axis and changing the attack angle. Rollers comprise a frame, spherical discs, rolling rings, an axis, a stem with a spring, and are arranged behind centre hoes as capable of adjusting pressure at soil. Leaning discs of each pair of ridgers are installed symmetrically relative to a line of sown seeds at the identical sharp angle, opening of which is aligned with the motion of the bedder planter. Longitudinal axes of symmetry of rollers match the line of sown seeds.

EFFECT: invention will make it possible to increase quality of sowing of cultivated crops and to form soil ridges above sown seeds.

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 an adjusting plate, L-shaped bracket with a half shaft and a pivoting disk are fixed to the frame in a checkerboard pattern. The L-shaped bracket is mounted on the adjustment plate, and the tipping disk is fixed on the axle shaft with the possibility of rotation around its axis and changing the angle of attack. Packer rollers containing a frame, spherical discs, packer rings, an axle, a rod with a spring, are located behind the pointed arms, with the possibility of regulating the pressure on the soil. The tacking discs of each pair of combing machines are set symmetrically with respect to the line of sown seeds at the same acute angle, the solution of which is directed along the direction of the ridge seeder, and the longitudinal axis of symmetry of the packer rollers coincide with the line of sown seeds.

Figure 1 shows a 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 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 a mounting disk 11. Holes 12 are made on the adjusting plate 8. A 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. A cylindrical body is fixed on the mounting disk 11 with 16 with the bearing 17. The overturning disk 11, by means of the bearing 17, is mounted on the axle shaft 10 with the possibility of rotation around its axis and changing the angle of attack. The required angle of attack of the flailing disk 11 is set by rotating the L-shaped bracket 9 together with the axle shaft 10 and the flailing disk 11 around the bolt 13 and fixed in the desired position by a bolt 14 inserted into the holes 12. The flailing discs 11 of each pair of comb-formers 4 are mounted symmetrically with respect 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 seed drill seeder are fixed by means of brackets 18 and are located behind the comb generators 4. The packer rollers 3 contain a frame 19, spherical discs 20, packer rings 21. Spherical discs 20 and packer rings 21 are mounted on the axis 22 with the possibility of rotation. The press rollers 3 also comprise a rod 23 with a spring 24. By means of the spring 24, the pressure of the press roller 3 on the soil is adjusted. 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 25 with the opener legs 26 mounted on the frame 1.

The ridge seeder operates as follows. Preliminarily using the sowing apparatus 2 set the required seeding rate. The required seed placement depth is set using the opener paws 26, as well as the depth of travel of the combing machine 4 with the mounting discs 11. By compressing the spring 24, the required roller pressure is set to the soil.

With the movement of the sowing unit, the coulters 26 and comb 4 with tacking discs 11 loosen the soil, weeds are cut. Sowing devices 2 through the seed tubes 25 direct the seeds to the opener legs 26, which lay the seeds to the desired depth. Coming ridge formers 4 with tipping discs 11 sprinkle seeds with a loose and heated 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 20 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 21 and due to the pressure of the spring 24, form a ridge of soil, compacting it on three sides. In this case, the packing rings 21 compact the top of the soil tubercle, and the spherical disks 20 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 tacking discs 11 mounted on a frame in a checkerboard pattern, and setting the tacking discs 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 direction of the ridge seeder, allows 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 formers 4 with the possibility of regulating the pressure on the soil, containing a frame 19, spherical disks 20, press rings 21, an axis 22, a rod 23 with a spring 24, improves the quality of formation of soil ridges above the sowed seeds, since it is formed above the 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.
