Description

FIG. 2

The invention relates to agricultural machinery, in particular to precision sowing seeds of agricultural crops, for example beets, radishes, carrots, with hole formation mainly by manual method in open ground, in greenhouses,

The purpose of the invention is to increase yield during operation of the navy, achieved by improving the conditions for planting seeds and increasing the efficient use of sown areas.

In FIG. 1 is a side view of a nylon; Fig. 2 is a nib, top view with cuts and implementation of a means for sowing seeds in the form of a drum; Fig. 3 is the same, with means for sowing seeds in the form of discs; figure 4 is a section aa in fig.Z.

The village contains a frame 1, on which a drum 3 is installed in the bearing bushings 2 with dimple 4, which form longitudinal circular rows (around the circumference).

The height of the hole formers determines the depth of seed placement in the soil, and their distance between themselves in the longitudinal and circular rows on the drum 3 determines the seeding step. So, for radishes, the height of the hole-forming agents 4 is taken equal to 30 mm, and the pitch is 70 mm.

On the frame 1 in the bearing bushings 5 there is installed a cylindrical means for sowing seeds 6, made either in the form of a drum 7 or in the form of discs 8. At its periphery, there are made 9 cells for seeds, the number of which in the longitudinal row is equal to the number of hole-forming agents 4 in longitudinal row of drum 3 and opposed to hole formers 4.

The cells 9 on the cylindrical seed meter b and the hole forming means 3 on the drum 4 are arranged with the same angular pitch equal to the seed pitch.

Cells 9 are made in the form of a scoop, the intake part of which is directed in the direction of rotation of the means for sowing seeds 6, and their rear wall is located vertically, which eliminates pinching of the seed and contributes to its entry into cell 9 and free exit from it into the hole on the ground.

A hopper 10 is mounted on the frame 1, which can be integral or made in the form of separate containers 11, which is advisable when the means for sowing seeds 6 in the form of discs 8 is made. In this case, each container 11 is located above the corresponding disc 8. Inside the hopper 10 or containers 11 mounted brush reflectors 12, providing a single selection of seeds, The function of these wires is performed directly by cells 9, transporting seeds from the hopper 10 or containers 11 until they enter the zone

landing, and guide flaps 13, each of which is connected to the hopper 10 and covers without a gap the outer surface of the drum 7 or discs 8. The guide flaps 13 do not reach the vertical axis

drum 7 or disc 8 in their lower part and are bent, which contributes to a better entry of seeds into the wells. The size of this gap is established experimentally. This form of execution of these wires

5 also helps simplify the design of the nylon, although other forms of execution are possible.

The village is equipped with marker discs 14 for fixing the processing edge (sowing) mounted on the axis of the drum 3 with hole-forming agents 4 at its ends at a distance from the extreme rows of hole-forming agents 4, equal to half the seeding step. The village is equipped with a handle 15, which is associated with

5 by frame 1 toothed couplings 16 for positioning the handle 15 in a position most convenient for the user (shown by a dotted line). Clutches 16 are clamped by screws 17. On frame 1 in front of the drum

0 h, a roller 19 is installed in the bearing bushings 18, which, in addition to transport functions, allows you to prepare the soil before the formation of holes by the hole-forming agents 4, and to improve their penetration

5 and reduce seed loss during the transfer of the nest to work in the next row due to the withdrawal of hole formers 4 from meshing with the soil. Drum 3 with dimple 4 is kinematically associated with

0 by cylindrical means for sowing seeds 6, with a gear ratio of 1: 1, which can be implemented as a chain drive 20, or gear, V-belt, etc.

5 Behind the seed sowing means 6, a chain 21 is loosely suspended on the frame 1 and contacts the soil and serves to fill the wells with soil after planting. 1 removable load attached to the frame 22

0 allows the use of the navy for work on soils with varying degrees of density.

Selka works as follows. Raised in the handle 15 so that the hole formers 4 do not touch the soil,

5, the roller 19 is delivered to the site to be sown and the seeds are put into the hopper 10 or container 11. By positioning the handle 15 so that the roller 19 does not touch the soil, the nest is moved forward. Thanks to the roller-sinker 19, drum 3 rolls over the soil along it

of the outer surface, and hole-forming agents 4 are immersed in the soil to a predetermined depth, in the form of holes, the shape of which guarantees the entry of seeds into them. In addition, during the movement of the village, the ice rink 19 breaks up a lump of earth, levels the soil in front of the hole-forming agents 4, thereby providing preliminary soil preparation. Through transmission 20, rotation is transmitted to the seed sowing means 6, into the cells 9 of which the seeds fall. Sem captured by the cell 9 passes under the reflector 12 and is in the area of the guide plate 13, which prevents the seed from falling prematurely into the soil. After leaving the shields 13, the seeds fall into the holes, which are covered with soil by the chain 21. Rotating together with the drum 3, the marker discs 14 form grooves on the soil, fixing the sowing boundaries. When they reach the end of the filled area, the handle 15 is lowered and turned on the roller 19 in the opposite direction. At the same time, the hole formers 4 are brought out of contact with the ground and, as a result, the means for sowing seeds 6 does not rotate and the seeds do not leave the hopper 10 or containers 11. For sowing the next section, one of the marker discs 14 must be installed in the previously formed furrow and continue work.

The village of the present invention allows the efficient use of the seed stock and sown land.
