Description

The invention relates to agricultural machinery, in particular to coulters for the subsurface spreading of crops, at the same time producing, their pre-sowing treatment and distribution of seeds under the top loosened soil layer to the same depth evenly over the entire area of the furrow.

Coulters known for the same purpose are known, consisting of a pointed blade, a hollow seed post and a seed distributor made in the form of reflective plates of different shapes or a guide surface with ribs.

However, these coulters do not provide good quality sowing. Lancet paws of productive cultivators do not satisfy agrotechnical requirements for sowing. Replacing a conventional cultivator leg with a LAY-resistant seed wire greatly increases its cross-sectional size. Such an opener at the opening of the furrow forms a larger pressochniky hill and causes a greater scatter of the soil, which occurs when cultivated with a similar paw. In addition, such a coulter fills more soil and envelops plant residues as compared to a cultivator foot, which also worsens the condition of furrow formation and increases the resistance of the coulter.

In the proposed opener, the legs of the paws are set at an angle to the horizon, the smallest at the front and increasing towards their ends, and the rack is designed as a skid, towards

to the posterior end of which is a CBOeii with a front part attached to the paw, which is, as it were, an extension of the stand.

Installing the shelves of a paw at a variable angle to the bottom of the furrow

the central part of the opener and increasing evenly to its edges) facilitates the lifting of the soil in the central part of the opener, reduces its spread and provides the required density of seed distribution.

The frost-shaped strut and spontaneous armature sem-welded wire on it have a blunt angle of entry and are displaced when working in an undeformed soil layer, which in turn significantly reduces the spread of the soil and the formation of ridges.

The drawing shows the opener in two projects.

The vomer consists of a lancet paw /, an izozoobraznoy stand 2, an arc-shaped sem wire 3 and a distribution socket 4 with guiding ribs 5.

The Iri movement of the coulter is located in front of the linozid stand 2 cuts the soil without significant spreading. Shelves paws, undercut layer of soil and lift it,

open the bottom of the furrow and form a cavity under the vomer for the distribution of seeds. Seeds from the metering device are transported by the air flow along the arcuate sem wire 3. Under the action of centrifugal forces, the seeds move in the sem wire against the bottom wall. Due to this, the seeds are thrown into the socket 4 and fed to the distribution surface.

Seeds ejected from the switchgear, before they are powdered by the soil, move in the same plane, which ensures their good distribution in area and depth.

The subject invention

Claims (2)

1. Soshnik, including a stand with a lapel paw attached to it, under which A seed distributing device is arranged, characterized in that, in order to reduce soil spreading during the formation of a furrow and more uniform distribution of seeds in it, the legs of the paws are set to the horizon at an angle the smallest in the forward part of the coulter and increasing to its ends. 2. The collet of claim 1, characterized in that the rack is designed as a skid, towards the rear the end of which has its paw attached to its front.
