Abstract

This invention relates to agriculture. The aim of the invention is to reduce energy consumption by increasing the depth and reducing the width of the loosening zone. In the soil 1, two rows of chips 2 and 3 are cut off in layers with the help of loosening elements 4 and 5 with the formation of a zone of loosening extending to the surface of soil 1. Each overlying chips 2 and 3 are cut ahead in relation to the underlying. Chips 2 and 3 are cut with a shift to the center of the loosening zone 6 under the action of the resultant force P _I directed at an angle α to the center of the zone of loosening 6. Each chip 2 belonging to one row and chip 3 belonging to another row are cut off down the depth of loosening 6. Each chip 2, belonging to one row, and chips 3, belonging to another row, is cut off downwards along the depth of loosening relative to the previously cut chips of another row, equal to H = (0.25-1) BI where BI is the width of the loosening zone at the level of cut I of the chip. 1 il.

Description

The invention relates to agriculture, and in particular to methods of deep loosening of the soil and subsoil.

The purpose of the invention is to reduce energy consumption by increasing the depth and reducing the width of the loosening zone.

The drawing shows a diagram of the implementation of the proposed method for deep loosening of soils.

The method of deep loosening of soil includes layer-by-layer cutting in soil 1 of two rows of shavings 2 and 3 using loosening elements 4 and 5 with the formation of loosening zone 6 expanding to the surface of soil 1, each cuttings 2 and 3 are cut from the underlying.

Chips 2 and 3 are cut with an offset to the center of the loosening zone 6 of the resulting force directed at an angle <}) m a = 90 ± 20 ° - (γ + β,) = 55 Я0 ° —β /, under the action where γ is the angle of the required lateral expansion of the cuts in soil 1, formed when blocked cutting; β, is the angle of the necessary lateral expansion of the loosening zone 6 at the cut level of the t-th chip. Each chip 2, belonging to one row, and chip 3, belonging to another row, is cut with an offset downward to the depth of cultivation relative to the previously cut chips of another row, equal to /: (= (0.25 — l) bi, where bi is the width of the loosening zone at the cutoff level: th shavings The method of deep loosening of soil is carried out both by separate subsequent loosening of the soil elements in the soil, and by means of the soil elements combined into a system.

An example of the implementation of the method with the individual movement in the soil of loosening elements.

To implement the method using, for example, a single-rack tractor cultivator with a loosening share, inclined at an angle a = 30 ° to the side surface of the vertical rack. The stand with a ploughshare is buried to the depth of loosening of the upper dowel, for example, to a depth of loosening of 80 cm, and the loosening process is carried out. At the end of the loosening path, the tractor with the cultivator is turned in the opposite direction. The stand with the ploughshare is deepened to a depth exceeding the depth of loosening of the first layer, for example, to a depth of 130 cm, while its lateral displacement by an amount providing the necessary width of loosening the soil at a depth of 130 cm, for example 40 cm. Then the stand with the ploughshare is moved with the specified lateral displacement with a tractor along the track parallel to the previously passed loosening track. A tractor with a cultivator is developed, they dig and continue cultivating in a similar way the deeper layers of the soil to obtain the cultivation zone of the required depth.

An example of the implementation of the method while moving loosening elements in the soil.

The loosening elements are combined into one system, for example, into the working body of a ripper, a drainer, a film layer, a cable layer. The loosening elements of the working body are placed at an angle to the vertical and set in the direction of the loosening path ahead of the above loosening elements in relation to the lower loosening ones, for example, with an offset uniformly distributed for all loosening 20 elements, the total value of which is equal to the depth of the required loosening zone. Each loosening loosening element is installed with a lateral displacement relative to the upper loosening by an amount corresponding to the width of the required loosening zone at the level of chips cut by it and with a vertical displacement equal to 0.25-1 magnitude of the lateral displacement. Loosening is carried out by simultaneously moving 30 loosening elements in the soil.

The proposed method allows to reduce by 1.5–2 times the mutual compression force of the cut soil chips, which makes it possible to reduce the width of the loosening zone at its considerable depth35 and thereby reduce the energy consumption of the process of loosening soil to a greater depth.
