Description

The invention relates to the field of forestry and can be used to create sub-canopy crops in local areas and promote reforestation.

A known manual seeder is a cane (patent No. RU2154367 published on August 20, 2000), containing a hollow tubular rod for seeds with a sowing apparatus and a pusher, a spring-loaded seed tube telescopically connected to the hollow rod with a device for forming a seed bed and a support ring, characterized in that in the seed tube spiral grooves with straight sections are made, and in the tubular rod there are transverse grooves, while the tubular rod is equipped with a rotary dispenser with a finger, which is located between the upper and lower plugs, the latter also has a finger, and the finger connected to the dispenser interacts with the transverse and spiral grooves, and the finger connected to the lower plug has spiral grooves; in addition, the seed tube has the ability to rotate on the support ring, and rippers are mounted on its guide sleeve.

The disadvantages of the analogue include the complexity of the design, the impossibility of group sowing of seeds in a line, and damage to the seeds.

A hand-held cultivator is known (patent No. RU2153787 C1, published 08/10/2000), containing a sliding handle, to which a vertical rod is rigidly connected with a working body fixed in its lower part in the form of sharpened spatially spiral-shaped teeth, which are paired, parallel-directed spirals of different radii, characterized in that the handle is S-shaped and asymmetrically mounted on a vertical rod at an angle to the horizontal plane.

The disadvantage of the analogue is the lack of the possibility of organized seeding and the complexity of the design.

A cane seeder is known (patent No. RU2377755 C2, published on January 10, 2010), containing a hollow tubular body with a compartment for seeds and a sowing apparatus having a spring-loaded rod with a handle and a metering element and a chamber for preliminary discharge of doses of seeds, characterized in that the sowing apparatus is equipped with its own body with a base with pointed edges and a central hole for the passage of the rod, having a funnel-shaped section on top, and a hole former-ripper at the bottom, and a seed loading chamber located directly above the seed preliminary discharge chamber, while the upper end of the sowing apparatus body has the shape of a truncated cone with holes in the center for the passage of the rod and at the base for supplying seeds, and the upper washer of the seed preliminary discharge chamber is made in the form of a funnel made of elastic material, and the rod is installed with the ability to rotate relative to the body, and the metering element on it is made in the form of downward inclined round cells in the seed loading chamber area.

This technical solution is closest to the declared one and is accepted as a prototype.

The disadvantage of the prototype is the complexity of the design, the impossibility of group sowing of seeds, and the damage to the seed coat.

The purpose of the proposed invention is to improve the quality of sowing seeds in the sowing line, simplify the design, and increase the reliability of the device. This is achieved by the fact that the device for sowing coniferous seeds, including a container and a rod with a sowing apparatus, handles, rippers, is equipped with a dispenser for individual supply of seeds to the sowing line, which is made in the form of a cylindrical container with a bottom and a lid, installed and secured coaxially on boom, including rotating blade blocks with a brush coating and an end-profiled surface, a system of seed tubes, air channels, shut-off valves, accumulators - pneumatic compressors, rippers with blades.

The invention is illustrated by drawings, where in FIGS. 1 shows a general view of the device; in fig. 2 - section A-A; in fig. 3 - sowing area; in fig. 4 - ripper with blade.

The device includes a container with a body 1, a lid 2, handles 3, 4, a rod 5, a check valve 6, air channels 7, a die 8, nozzles with seed tubes 9, a brush coating 10, a flange 11, blades 12, a pneumatic air accumulator - compressor 13, rotation angle limiter 14, rippers 15 with blades 16, loading funnel 17, end-profiled part of the blade 18. In FIG. Figure 3 shows a sowing area with sowing lines 19.

The operation of the device is carried out as follows: a portion of coniferous seeds is loaded into a container with a housing 1, fixed through a flange 11 on a rod 5, through a loading funnel 17 in the lid 2 and the device is installed vertically on the surface of the sowing area until the rippers 15 with the dumps 16 come into contact with the soil. Handle 3 is used to turn and set the block of blades 12 to its original position (Fig. 2) without overlapping the blade of the die 8, and the end profiled part of the blade 18 is in contact with the elastic shell of the air pneumatic accumulator - compressor 13, compressing, deforming it, reducing the volume of air in the shell, which is removed through shut-off valves (not shown).

From the array of seeds initially covering the die 8, one seed enters the cell of the die, then when the block of blades is rotated, the array of seeds is shifted along the bottom by the brush coating 10 without damaging the seeds, and the end profiled surface of the blade is removed from contact with the battery shell, at the same time the shape and volume The elastic shell of the air pneumatic accumulator - compressor 13 is restored when filled with air through shut-off valves (not shown). The block of blades is rotated with handle 3 to the rotation angle limiter 14, while simultaneously holding the body with handle 4, and then together with handles 3 and 4, turn the rod 5 with the ripper 15 to an angle α, which determines the size of the seed line 18. In this case, the blades 16 are immersed in the ground and form sowing line on sowing pad 17. At the same time, seeds are fed through seed tubes to the sowing line. After this, by turning the handle 4, the rod 5 with the container with the body is returned to its original position. When the ripper moves back, the back side of the blade covers the seeds in the row with soil.

When returning to its original position and rotating the block, the blades with their end profiled part contact the elastic shell of the pneumatic accumulator-compressor, deforming and reducing the volume of the pneumatic chamber, creating excess air pressure in the pneumatic accumulator-compressor, which exits through the valves (not shown) and enters the cavity of the container with housing 1, increasing the air pressure in it, check valve 6 closes. The shell of the pneumatic accumulator-compressor is made of an elastic-elastic material (elastomer) and is equipped with a system of standard valves that ensure air exchange in the housing.

Under the influence of excess pressure, air from the container body through the air channels 7 and the side surface of the brush cover 10 is supplied to the die 8 with the seed, ensuring the transportation of the seed through the nozzles with the seed tubes 9 to the sowing point in the line (shown by arrows). The inner surface of the seed tube is made of material with low tribological characteristics (for example, Teflon), which increases the reliability of seed transportation.

At the end of the operation, the device is moved to a new sowing area.

Thus, the claimed technical solution makes it possible to simplify the design of the device, avoid damage to seeds, and increase the reliability of individual seed sowing.

The disadvantage of the analogue is the lack of the possibility of organized seeding and the complexity of the design.
