Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. Proposed method of sowing seeds of grain crops. Method consists in seeding the seeds in depth with sowing discs, which have the property of changing the seed sowing patterns. Sowing of seeds of grain crops is carried out by dotted, or combined, or nested sowing using sowing discs with a pad and four groups of holes located on the discs, three on each side, wherein seed sowing patterns are changed by overlapping appropriate holes on discs by shifting the pad in a circle.

EFFECT: method makes it possible to carry out dotted, combined and nested methods of sowing of seeds with change of schemes of sowing of various crops on one area without additional operational and financial costs.

Description

The invention relates to the field of agriculture, and in particular to methods for sowing various crops.

A known method of combined sowing of cereals and peas, where the sowing of seeds is carried out according to the scheme of two rows of cereals and one row of peas (USSR Author's certificate 784824, IPC A01C 7/04, 1988).

The disadvantage of the known device is that the seeds of different crops are sown in different rows, the sown area is used inefficiently, and where the sowing occurs in one row, the seeds are sown randomly, their seedlings oppress each other due to violation of the feeding area set for each crop.

The closest in essence to the claimed device is the method of combined sowing chosen as a prototype, which consists in dotted and combined sowing and planting seeds at different depths with seeding discs made with the possibility of changing sowing patterns. Simultaneous sowing of seeds of two crops and their placement at different depths is carried out, alternating in one row with an offset and with the same interval between them, while the offset of seeds in a row is determined by the condition L= a + 2b mm, where a is the distance between the sowing disks, mm, b is the thickness of the sowing disc, mm, and the alternation of seeds is carried out according to the scheme: 1:1; 1:2; 1:3; 1:4. (patent RU No. 2582367, IPC A01C 7/00, 2016).

A disadvantage of the known device is the inability of one sowing device, without changing the sowing discs, to change schemes and methods of sowing seeds remotely from the tractor cab.

The objective of the invention is the possibility of changing the scheme and methods of sowing and reducing the operating time for readjusting the sowing device.

The task is achieved by the fact that in the method of sowing seeds of grain crops, which consists in planting seeds in depth with sowing discs that have the property of changing seed sowing patterns, according to the invention, sowing seeds of grain crops is carried out by dotted or combined or nested sowing using seeding discs with an overlay and four groups of holes located on the disks, three in each direction, while the seeding patterns are changed by overlapping the corresponding holes on the disks, shifting the overlay in a circle, the intergroup distance is determined by the condition S ≥ 3d + 2a, mm, where S is the intergroup distance, mm; d - hole diameter, mm; a - distance between holes in a group, mm; and the distance between the holes of each group is at least not less than the diameter of the holes; the openings are closed remotely from the tractor cab by wireless control of the actuator.

The invention is illustrated by drawings.

In FIG. 1 shows a diagram of a sowing disc with four groups of three holes; figure 2 - the same, with two holes; figure 3 - the same, with one hole; figure 4 - scheme lining with four groups of three holes; figure 5 - the same, with two holes; Fig.6 - the same, with one hole.

The device for performing the method of sowing seeds of grain crops contains two sowing discs 1 installed on a common shaft, with holes 2 and pads 3 with holes 4. The holes on the discs 1 and pads 3 are placed in four groups of three holes each.

The intergroup distance on disk 1 and pad 3 is determined by the condition S ≥ 3d + 2a , mm, where S is the intergroup distance, mm; d - hole diameter, mm; a is the distance between the holes in the group, mm, which is at least not less than the diameter of the hole.

The openings are closed remotely from the tractor cab by wireless control.

The method is carried out as follows.

The seed hopper is divided by a partition into two parts, into which the seeds of two crops are poured (not shown in the figure).

Example 1 . With nesting sowing.

Before working in the sowing machine, two sowing discs 1 with overlays 3 are installed on the axle.

From the tractor cab, the operator remotely controls the actuator, and pad 3, rotating clockwise, covers one hole on disk 1 in each group. Thus, on disks 1, 8 holes remain working, however, 2 holes in a group. This means that the sowing of seeds is carried out in two rows of two seeds in a nest of two different crops, for example, row crops and legumes.

Example 2 . With combined sowing.

Two disks 1 with pads 3 are installed on the shaft.

When the lining 3 is displaced in a circle, one hole is left open in the group. In this case, the combined sowing of seeds of two crops is carried out, one seed per crop.

Example 3 . With dotted single-grain sowing.

One of the disks 1 is involved in the work. One section of the bunker is filled with seeds of one crop. Rotating pad 3 on disk 1 changes the sowing pattern, leaving one hole in groups.

Example 4 . Nested sowing.

Two disks 1 with overlays are involved. Seeds of two crops are placed in the bunker.

The holes on disk 1 are not blocked, the seeds are sown in the nest method, 3 seeds per nest.

To create the best conditions for germination and growth of plants, care should be taken to ensure that the plants receive enough moisture, nutrients and space to grow.

The proposed technology of sowing seeds of grain crops makes it possible to improve the sowing process by using remote control, which contributes to changing the schemes and methods of sowing seeds and reducing the operating time for readjusting the sowing device.
