Description

(54) DEVICE FOR INTRODUCING MINERAL FERTILIZERS

I

The invention relates to agriculture, and more specifically to devices for applying mineral fertilizers to the soil, and is intended to increase soil fertility on fields located on slopes.

A device for sowing forest seeds with a moistened mixture of fertilizers, soil and other additives is known, including a cylindrical bunker with an outlet in the cone-shaped lower part, and an extrusion rod mounted vertically inside it, kinematically connected with a crank mechanism. The device regulates the seeding rate and the dose of fertilizer I.

A disadvantage of this device is that the seeds, together with the fertilizers, are sown on the soil surface and therefore are quickly washed away from the surface by the soil water flows, especially in those parts of it that are located on the slopes.

It is also known a device for applying mineral fertilizers to the soil, including a bunker with a pipeline, and a embedding mechanism located behind the pipeline. The known device provides for the incorporation of mineral fertilizers into the soil in 0olV SOIL

depth, which reduces washing them with water 2.

However, on sloping soil areas, the washing of mineral fertilizers with water flows is still quite large, which reduces the efficiency of their use.

The purpose of the invention is to increase the efficiency of use of mineral fertilizers on sloping soil areas.

This goal is achieved by the fact that in a device for mineral fertilization of rhenium into the soil, including a bunker with a pipeline, and a seeding mechanism located behind the pipeline, the latter is made in the form of two successively installed circles after the other along the guides placed in the new plunger 5 m and two shoulder rocker, the ends of which are connected to the piston rods, and the rod located closer to the pipeline, has a greater length.

The drawing shows a device for applying mineral fertilizers to the soil,

20 side view.

The device contains a hopper 1 with a pipeline 2 and located behind the pipeline 2 sealing mechanism, made in the form

Claims (2)

Claim Apparatus for making mineral fertilizer into the soil, comprising a hopper with tukoprovodom and located behind tukoprovodom mechanism seal, characterized ²⁰ in that, in order to improve efficiency in the use of mineral fertilizers on sloping ground soil mechanism seal is in the form of two sequentially arranged one behind the other on ₂₅ zheniya course motion guides with pistons disposed therein, and a two-armed rocker arm whose ends are connected to the plunger rod, wherein the rod located closer to tukoprovodu has more u length. 30 Sources of information taken into account in the examination 1.
