Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to breeding villages.

The purpose of the invention is to improve the uniformity of placement of the nests of seeds on the field along the vertices of regular triangles.

1 shows a plant view from above; FIG. 2 - placement of nests of seeds on the field.

The crop contains frame 1, support wheels 2, sections 3, first shaft 4, second shaft 5, left knotter 6, right knotter 7, other nodes (not shown).

Section 3 includes a linkage mechanism 8, a coulter 9 with a valve (not shown), a valve mechanism 10 of the coulter 9, a sowing unit 11, a support-drive wheel 12, and a chain transmission 13.

At the ends of the first shaft 4, the left lever 14 is rigidly fixed with an axis 15 and the right lever 16 with an axis 17. Levers 18 are rigidly fixed on the first shaft 4. Levers 18. Each long ha ha 19 is pivotally connected to the lever 18 and the opener valve mechanism 10 9. First

shaft 4 is installed with the possibility of rotation in the bearings 20.

At the ends of the second shaft 5, the left lever 21 is rigidly fixed with the axis 22 and the right lever 23 with the axis 24. Levers 25 are rigidly fixed on the second shaft 5 The second shaft 5, as well as the first 4, is mounted rotatably in the bearings. Each short ha 26 is pivotally connected to the lever 25 and the valve mechanism 10 of the odd coulter 9 (the number of the coulters to the left in the direction of movement of the crop).

On the left bracket 27 is fixed left knotter 6. On the right bracket 28 is fixed right knotter 7. Left 6 and right 7 knotters contain a front fork 29 and a rear fork 30

The front fork 29 is rigidly connected to the crank arm 31, which has the ability to rotate in the bearing 32. The rear fork 3.0 is rigidly connected to the crank arm 33, which has the ability to rotate in the bearing 34.

The first shaft 4 is kinematically connected with the front fork 29 of the left catcher 6 with a leash 35 and with the rear fork of the right catcher 7 with a lead 37.

The second shaft 5 is kinematically associated with the front fork of the right catcher 7 with a leash 38 and with the rear fork 30 of the left catcher 6 with a leash 36.

Wooppm 23 m 30 are installed on the left catcher b and right catcher 7 at a distance t equal to half the distance between the stops of the measuring wire and determined by the formula, where b is the distance between the openers.

The cutter is equipped with measuring wire 39 with thrust washers 40 fixed on it rigidly at a distance equal to the size of the inter nest.

Selka works as follows.

Before the start of sowing on the field, the measuring wire 39 is stretched and secured in a known manner sequentially from each of the two sides, providing the possibility of its mechanical transfer by the pit. The tractor driver feeds the measuring wire 39, which has stops 40, into the knotter, for example, into the left knotter 6, and starts moving the unit along the measuring wire 39 along the field.

When rotating the support wheels 12 sections 3, each sowing unit is driven into rotation by a chain drive 13 and feeds 9 seeds to the opener per valve (not shown). Each stop 40 of the measuring wire 39 deflects successively the front fork 29, and then the rear fork 30 of the left knotter 6, the Front fork 29, turning in the bearing 32, through the crank lever 31, the lead 35, the axis 15, the lever 14, turns the front shaft 4 with the levers 18, which, through the long traction bars 19, drive the valve mechanisms 10 even (the numbering on the left in the direction of spraying) openers 9 and portions of seeds from the valves (not shown) are thrown into the furrows made by the openers 9, and form slots 41 (figure 2), located on the same cross 42 ns.

After the spreader has moved by an amount equal to the distance between the forks 29 and 30 of the left catcher 6, the same fork 40 deflects the rear fork 30 of the left catcher 6. The rear fork 30, turning in the bearing 34, using the crank lever 33, the leash 36 , axis 22, lever 21 rotates the second shaft 5, and with it the arms 25, which through short ti 26

The valve mechanisms of 10 odd coulters are driven, and portions of seeds from valves (not shown) are thrown into grooves made by odd coulters and form slots on the transverse line 43 (Fig. 2).

The distance t (Fig. 2) between adjacent transverse lines 42 and 43 of the sockets 41 is equal to the distance between the front fork 29 and

rear fork 30, equal to half the distance between the stops measured wire, and

.. also where b is the distance between

openers.

After the first pass, the unit stops. The measuring wire is withdrawn from the left catcher 6, the aggregate unfolds and stops at the initial position for the second pass.

The tractor driver transfers the end of the wire with the fastening device and installs it at the rear of the right knotter 7. Fill the measuring wire into the catcher 7.

The seeding process is repeated.

from the front fork of the right knotter 7, through a system of levers and a pull of the catcher 6 with each washer 40, the movement is transmitted to the valve mechanisms of 10 odd coulters, and from the rear fork of the right knot 7 to the valve mechanisms of even coulters.

The cycle is complete.

He then repeats.

The crop provides an increase in the uniformity of placement of seed nests on the field along the tops of regular triangles during mechanical transfer of the measuring wire, simplifying the design and increasing productivity.
