Abstract

FIELD: agriculture.

SUBSTANCE: opener comprises a cultivator A-hoe, a hoe stand, a drill tube, a distributor of seeds. The end of the drill tube is located in the space under the hoe. The distributor of seeds is made of polyamide in the form of a hollow housing. Inside the housing a flexible divider is pivotally mounted on the axle with the ability to adjust the amplitude and frequency of vibration depending on the physical and mechanical and aerodynamic properties of the seeds by air velocity.

EFFECT: even distribution of seeds on the operating width of the A-hoe.

Description

The invention relates to agricultural machinery, in particular to openers producing subsoil-spread sowing.

Known opener for subsoil spread sowing, which has a lancet paw, receiver and distributor of seed, and also a arch for limiting from above the sublap space. The distributor is installed in the sublap space on the way of the seed to be sown from the receiver. In the said opener, the distributor is made in the form of a trihedral pyramid or a wedge-shaped divider with gable lateral and rear faces, or in the form of a cone mounted hinged, with the top up, with the possibility of moving its base along the bottom of the furrow, revealed by the lancet paw of the opener, that is, on the seedbed [ one].

The opener-analogue does not provide a high-quality distribution of seeds in the sublapar space, which is especially manifested when the lancet paw has a working width of about 300-420 mm (the opener with such a paw, hereinafter the wide opener).

The prototype of the claimed device is a coulter for spreading sowing, including a hollow stand, lancet paw, horizontal shelf, a vertical plate connected to a vibrator. The incoming seeds are oscillated by the plate dispersing alternately under the left and right wing of the lancet paw [2].

This coulter has several disadvantages: installing a vibrator for each coulter complicates and increases the cost of construction; the sowing material is distributed unevenly along the width of the paw, since the vertical plate alternately directs the seeds under the right and left wings of the lancet paw; a vertical plate connected to a vibrator injures the seeds due to impact action.

The purpose of the invention is to increase the uniformity of the distribution of seeds across the width of the paw, simplifying the design.

To achieve this, the seed distributor is made of polyamide in the form of a hollow body, inside of which an elastic divider is pivotally mounted on the axis, which makes stable self-oscillations under the influence of ejaculatory flow, the amplitude and frequency of oscillations of the end of the elastic divider being regulated by the air flow rate depending on the physicomechanical and aerodynamic properties of grain seeds. The implementation of the distributor of polyamide simplifies the manufacture of a hollow body, and also reduces injury to seeds.

Figure 1 shows the inventive opener with distributor, side view with local cuts; figure 2 - the inventive opener, rear view; figure 3 is a section aa of figure 1.

Figure 1-3 adopted the following position designations: 1 - lancet paw; 2 - rack; 3 - vas deferens; 4 - seed distributor; 5 - elastic divider; 6 - axis; 7 - holder.

The opener for the subsoil-spread sowing (Figs. 1-3) includes a lancet paw 1, bolted to the rack 2, a seed-air duct 3, at the end of which a seed distributor 4 is made, made of polyamide in the form of a hollow body, inside of which it is hingedly mounted on axis 6 elastic divider. The distributor is attached to the holder 7, and the holder to the rack 2.

The opener for subsoil-scatter sowing of seeds is as follows.

In the working position, the opener (figure 1, 2) moves in the soil at a given depth of sowing. An arrow-shaped paw 1 cuts a layer of soil, a furrow opens and its bottom is compacted, forming a sowing bed. The seed material comes from the sowing apparatus (Figs. 1, 2, 3, not shown) into the seed-air line 3, where it is picked up by the air flow and fed into the seed distributor 4. Under the influence of the seminal air flow and elastic properties, the elastic divider 5 is driven in self-oscillating motion . Self-oscillating motion and air flow contribute to a more uniform distribution of seeds in the sublapaceous space.

When the coulter moves, the bottom of the furrow with sown seeds is covered with a loosened layer of soil descending from the upper surface of the lancet paw 1.

Thus, the proposed device provides the following advantages: improves the uniform distribution of seeds due to the reflection of seeds on the surface of the elastic plate and on the surface of the furrow, simplifies the design of the coulter, reduces injury to seeds.
