RU152690U1 - COMBINED SEED UNIT - Google Patents

Abstract

The combined sowing unit contains a seed box divided into three sections, the middle section for seeds of grain crops, and two side sections for fertilizers, seed tubes and pipelines, a flat-cutting paw, characterized in that a chisel-like paw and a disk coulter are fixed to the mounting stand of the flat-cutting paw, connected by the vas deferens with the middle section of the seed box and with one side section for fertilizers, while a fertilizer coulter mounted between the disc coulter and the chisel-leg stand koprovodom the second side section of the fertilizer, the fertilizer distributing coulter is mounted with the possibility of changing position relative to the coulter disc in a plane perpendicular to the soil surface.

Description

The utility model relates to agricultural machinery, in particular to the production of sowing equipment.

Known combined tillage and sowing units [1, 2] which design provides for the combination of various technological operations in a single working process of one machine. This ensures a reduction in technological operations and reduces the number of agricultural equipment used.

Aggregates are known [3, 4], the design of which provides for the introduction of fertilizers directly into the row and to a depth below the location of the row of plants.

By the totality of common essential features, the technical solution [4] is taken as a prototype.

The disadvantages of the known devices.

1. The lack of effectiveness of fertilizers included in the row of crops.

2. The complexity of the design of the working bodies for fertilizing. The task to which the claimed utility model is directed,

is to increase the efficiency of layer-by-layer application of fertilizers in the soil simultaneously with its processing and sowing to increase the yield of cultivated crops.

The problem is solved due to the fact that, as in the well-known technical solution, the combined sowing unit contains a seed box divided into three sections, the middle section for seeds of grain crops, and two side sections for fertilizers, seed tubes and pipelines, a flat-cut leg. Unlike the known technical solution, the claimed device has a chisel paw and a disc coulter connected to the seed tube with the middle section of the seed box and one side section for fertilizers, with a fertilizer coulter installed between the coulter and the chisel leg. connected by a pipe line to the second side section for fertilizers. In this case, the fertilizer coulter is fixed with the possibility of changing the position relative to the disk coulter in the plane perpendicular to the soil surface.

The technical result is an increase in the efficiency of layer-by-layer fertilization in the soil and increase crop yields.

The technical result is achieved due to the design features of the combined sowing unit, namely the ability of the fertilizer coulter to move relative to the disc coulter in the plane of the perpendicular soil surface, while changing the depth of fertilizer application into the soil within the arable horizon. Fertilizing plants at the same time contributes to the development of the root system of plants and the formation of grain, which allows to increase the yield of cultivated crops.

The noted positive aspects of the claimed object allow to obtain the economic effect of its use and widespread practical application in the agricultural production system.

The drawing schematically shows a combined sowing unit.

The unit contains: seed box 1, divided into three sections, the middle section 2 of the seed box 1 for seeds of grain crops, and two side sections 3, 4 for fertilizers, seed tube 5, fertilizer line 6, chisel-like paw 7, flat-cutting paw 8, fertilizer coulter 9 and disc coulter 10.

The unit operates as follows. When the unit moves, a plane-cutting paw 8 loosens the soil for sowing. The seeds of cultivated crops from the middle section 2 of the seed box 1 through the vas deferens 5 enter the disc coulter 10, which seals them into the soil at a given depth.

At the same time, the chisel-like paw 7 loosens the soil, making a groove to the depth of the arable horizon. At the same time, fertilizers from the lateral section 3 of the seed box 1 through the fertilizer line 6 enter the fertilizer coulter 9, which plows them into the soil below the depth of sowing of seeds, depending on the cultivated crop.
