SU71817A1 - Disc Seed for narrow seeding - Google Patents

Description

Known crops for narrow sowing have working bodies, anchor-type coulters and are designed for sowing seeds at narrowed spacing of up to 7.5-6.5 cm.

The peculiarity of the invention lies in the fact that, in order to ensure uniform distribution of seeds over the sown area, due to further narrowing of the spacing between the rows to 6 and 5 cm, and active seeding of seeds to the same depth on the compacted bottom of the sowing groove, under a moist soil layer, In the described plant, there are working bodies (coulters), constructively designed in such a way that, during work in the soil, they embed the seeds in a narrow slit of the cut vertical soil.

The front part, or chest of the neck of such a coulter, consists of half the disk circumference and attached to it on the left side of the neck. The lower edge of the shear of such a coulter is curved with a convex bend to the outside, which is used to fill up the seeds with a wet stream of soil, which it is pressed from the wall in the lower part of the sowing furrow bottom.

FIG. 1 of the drawing shows a general view of a tractor tractor with a three-fold arrangement of coulters on the side; in fig. 2 - the same view from above, partially in section; in fig. 3 - a general view of the vomer with the cheek and its parts; in fig. 4 and 5 are common side views of tractor forks with a two-row arrangement of the same working bodies with a joint; in fig. 6 is a general view of a horse cutter with the same coulters and in FIG. 7 is a side view of the lifting unit assembly with the pivots of rods to the splitter with a three-row arrangement of openers.

The described crops are designed for narrow sowing on heavy soils with excessive moisture, and for this purpose they are equipped with openers well-penetrated in the soil.

No. 7.1817

On the main frame of 1 seed, a seed box 2 is fixed with conventional sowing machines and wires 3 coming out from each to the opener, a rack-and-pinion mechanism 4 for vertical movement of the entire coulter group when adjusting the embedment depth of the seed and running wheels.

In the front part of the frame 1, the vertical rail 5 is also strengthened, carrying at its lower end a transverse bracket 6, on which parallel-arranged soshnikov bars 7 and 8 of angular iron are rigidly fixed.

Leads 5 of the first and second row of disc soshnikov 10 are pivotally connected to the front coulter bar 7, and the tails of the third row of coulters are connected to the second coulter bar 8. The rear end of the driver 9 is connected by means of a lifting mechanism 14 coulters transport position or deeply them into the soil.

In the upper part of the discs, the bulging cheeks 12 are tightly fitted in the upper part, the bottom of which has a limb to the side of 6-7 and is curved (Fig. 3).

During the operation of the seedlings, a trickle of soil rises along the cheeks 12, the wet part of which moves along a bend and with some force rolls the precipitated depth to the compacted bottom of the sowing seed, the grooves in a row of grains. In this way, an active seeding of the seeds with a wet layer of soil at the same depth is carried out.

The cheeks 12 are reinforced in their upper part so that they are closely fitted to the disk, as a result of which they also serve at the same time as a disk clearing when the ground sticks.

Depicted in FIG. 4, 5, and 6 pitchers with a two-row coulter arrangement have the same working bodies, but due to the coulter arrangement not in three, but in two rows, in one case (Fig. 4) they are attached directly to the frame on curved leads and connected to an automatic lifting mechanism by means of pressure spring-loaded rods, and in the second case (Figs. 5 and 6) the coulters, also on curved leads, are attached to two coulter bars m suspended from the frame and brackets 15, 16 connected to the lifting mechanisms through spring-loaded push rods. In the tractor tractor with a three-row arrangement of coulters (Fig. 1) there is a manual-lifting mechanism (Fig. 7); In the horse-drawn field (Fig. 6) with a two-row arrangement of coulters, a manual lifting mechanism 14 is installed.

Subject invention

Disc seedling for narrow seeding, the coulters of which are equipped with a flat disc and adjacent to the last convex cheek, characterized in that the lower edge of the cheek is curved and bent outwards, which serves to sow the soil with a moist soil layer pressed out from the bottom of the channel. furrows
