Description

A whole number of hand, horse and tractor crops spread mainly in the forest sector, mainly for sowing the seeds of trees and shrubs in nurseries in rural forest stands, free from stumps and with well-treated soil.

Drum crops, made in the form of a cylinder, freely rolling on the soil, inside which are placed the seeds, ejected through rotary valves located on the ledges of the drum, and the seeds with spring-loaded valves located on the rim of the drum, in which, when immersed in the soil in the cavity the latter are seized and thrown into the soil, known.

These crops consist of the following main parts: a bunker for filling the seeds, a sowing apparatus, running wheels, with which the sowing apparatus of these wires and fittings are put into operation.

To combine these parts into one design, the cutters have a frame and axles. The use of existing crops in the unit with a forest cultivator or other cultivator that can loosen the surface of the soil on uncorrupted areas is impossible, since all parts of the seedlings will be out of operation when working on areas with logging residues and mon.

The disadvantage of these spouts is also the impossibility of sowing seeds of various forest species. In the described plant, this drawback is eliminated, since its design provides for the installation of replaceable pucks with openings of different diameters in the valve wall, which makes it possible to sow seeds of various forest species, thus transforming the seed into a universal one.

The proposed forest plant does not have parts that are separately partitioned from each other and is a simplified design of a wheel shape. All parts of this spindle are mounted in one hollow wheel, which gives it the opportunity to work freely on stumps and stumps when working on uncorrupted logging sites. The crop produces proportional seed sowing of seeds with subsequent insertion with a loop and works in an aggregate with a tillage tool.

The drawing shows a longitudinal section of a sowing apparatus (a), a longitudinal section of a wheel-seed without a sowing apparatus (b), also with a sowing apparatus, inserted inside) the wheels (c), the same with the sowing apparatus in the sowing position of seeds (g ), a valve with a seeding plate and a changeable plate (e), a plate of the seeding unit with a U-shaped slot, a partition and pins for hinging the valve (e).

The wheel rim / wheel is made of iron bar. Discs 2 are welded on both sides of the rim. In the central part of the hollow wheel, sleeve 5 is omitted and strengthened, and axle 4 is put on along with the wheel. With the aid of the cutting axis, a special thrust wheel is attached to the cultivator or other ripper. An axle for embedding seeds is also attached to axis 4 on the opposite side. The hollow portion of the wheel is a hopper into which seeds are poured through holes 5 in the rim. In this hole, the sowing unit is attached to the sockets 6 by means of bolts 7 and a plate 8 curved on the rim arc.

A U-shaped slot 8a is cut out on the plate 8, in which the valve 9, the sowing device and the sowing unit 10 connected with it are strengthened by means of bolt // and holes 12 in the side walls of the valve. The sowing plate 10 in its central part has a threaded hole for screwing in replaceable washers 13 having different diameters of the sowing hole 14, by means of which the seeding rate can be adjusted. The exchangeable washers have blind holes 15 on the outside for a special key, with which they can be screwed in or unscrewed from the seed plate.

On the inner side, across the plate 8, along the edge of the transverse slit, the partition 16 is reinforced, equal in height to the seed plate.

A plate spring 17 is located between the anges plane of the plate 8 and the inside plane of the valve cover, which holds the valve 9 and the metering plate 10 in the bent state. The stops 18 hold the valve and the seeding plate in the U-shaped slot.

Selka works as follows.

The wheel, rotating, presses on the valve 9. The spring 17 compresses and the side walls of the valve and the seeding plastic 10 enters through the H-shaped gap inside the wheel. At the same time, the sowing plate 10 slides tightly along the partition 16. The seeds, pouring, fall into the hole of the sowing plate and are retained in it by means of the partition 16. With further rotation of the seed wheel, the valve spring opens and opens the sowing plate from the U-shaped slot. Seeds that fall into the hole of the sowing plate fall into the furrow prepared by the ripper. The plumes following the seed close up the seeds. With a rim length of 1 m, the sowing of seeds will occur every meter.

Subject invention

A seedbed for seeding forest seeds, made in the form of a hollow cylinder, bearing on the surface rotary-mounted spring-loaded valves with seeding openings, which serve to hold the seeds when the valve is immersed inside the cylinder and then thrown out to the soil when the valve leaves the cylinder cavity, characterized in that, in order to carry out seeding of seeds of various breeds, interchangeable washers are used, mounted in the wall of the valve and having different diameters of the seeding hole.
