RU150940U1 - COMBINED SOIL PROCESSING, FERTILIZING AND SEEDING UNIT - Google Patents

Abstract

A combined tillage-fertilizer-sowing unit containing a seed box, flat-cutting legs with dental rippers, characterized in that on the back side of the flat-cutting legs, in their middle part, a keeled coulter is rigidly fixed, connected to a tubular-shaped fastening rack forming a pipe line, while the seed box is divided into three sections: the middle section for seeds of agricultural crops, two side sections for fertilizers, and one of the sections for fertilizers is connected by a duct with a keeled schnick, and the second section for fertilizers and the middle section for seeds of agricultural crops are connected by a seven-pipe line to the opener of a plane-cutting paw.

Description

The utility model relates to agricultural engineering, in particular, to the production of tillage and sowing units.

Known tillage and sowing units, the design of which provides loosening of the soil, sowing seeds and fertilizing to the depth of seed placement [1, 2, 3]. At the same time, fertilizers have an effective effect on plants in the first phase of their development, contributing to the emergence of friendly seedlings. As the plants grow, they need additional top dressing in the form of fertilizers located in the lower layers of the arable horizon. The design of the known units does not provide for this. Nevertheless, the use of tillage and sowing units in comparison with units that perform separate technological operations in the system of modern agricultural technology, allows to obtain stable crops.

One of such aggregates is an aggregate in which the working bodies produce the soil using a lancet paw on the back side of which the rippers are fixed along its contour [4]. By the totality of common essential features, this technical solution is taken as a prototype.

The disadvantages of the known devices.

1. The lack of effectiveness of fertilizers introduced into the soil by known methods.

2. Known aggregates do not provide for the introduction of fertilizers into the soil simultaneously at different levels of the arable horizon.

The objective of the claimed utility model is to increase crop yields and increase the efficiency of fertilizer use.

The task is carried out due to the fact that on the back side of the flat-cutting paws, in their middle part, a keeled opener is rigidly fixed, connected to a tubular-shaped fastening rack forming a pipe line. At the same time, the seed box is divided into three sections: the middle section for seeds of agricultural crops, two side sections for fertilizers, one of the sections for fertilizers being connected by a pipe line to a keeled opener, and the second section for fertilizers and the middle section for seeds of agricultural crops are connected by a seven-pipe with opener of flat-cutting paws.

EFFECT: crop productivity is increased, and the efficiency of fertilizer application is increased. The technical result is achieved through the use of a keeled opener, the design of which provides loosening of the soil and the process of fertilizing to the required depth - below the depth of seed placement.

Fertilizing directly in the zone of seed location and simultaneously below the depth of their placement leads to accelerated plant growth and the development of their root system. As the root system grows in volume, it receives moisture and top dressing from the lower horizon, which favorably affects the development of stems and spike formation, and generally contributes to an increase in the yield of crops grown. At the same time, the option of applying fertilizers, their effectiveness increases and allows you to get a positive economic effect and wide practical application.

The drawing schematically shows a combined tillage-fertilizer-sowing unit.

The unit contains a three-section box 1, the middle section 2 for seeds of grain crops, the side 3, 4 for fertilizers, the seven pipelines 5, the piping 6, the flat-cutting paw 7, the rack for attaching the working bodies 8, the keeled opener 9, the opener of the flat-cutting paw 10 for planting seeds with fertilizers and dental rippers 11.

The unit operates as follows. When the unit is moving, the seeds of agricultural crops from the box 1 of section 2 along with fertilizers from section 3 through the seven-ducts 5 are fed into the opener of the plane-cutting paw 10, which closes them into the soil to a predetermined depth. At the same time, fertilizers from the box 4 with the fertilizer line 6 through the fastening rack 8 enter the keeled opener 9, which seals them into the soil below the level of seed placement to a depth that determines the variety of crops grown. Thus, in one pass of the unit, the soil is loosened, including dental soil rippers 11, the seeds are sown and fertilizers are applied at different depths, directly into the seed zone and below their placement.
