Abstract

FIELD: agriculture.

SUBSTANCE: in the method originally 2/3 of the height of the upper part of the hillocks is milled. The milled mass is distributed between the hillocks. Before ploughing the remaining lower part of the hillocks with the milled mass is compacted.

EFFECT: method enables to improve the quality of ploughing, to reduce the complexity and energy consumption of processing the tussock swamp lands.

Description

The present invention relates to agricultural production and can be used in the treatment of soils covered with large plant bumps with a height of 50 *** 80 cm

A known method of processing soil covered with large plant bumps (Komissarov V.T., Preobrazhensky K.I. Cultural and Land Reclamation, M., "Kolos", 1972, S. 110-111), including grinding and stocking of bumps.

The disadvantage of this method is that with an increase in the height of the bumps, the volume of the crushed mass increases sharply. As a result, with a single pass, most of the bumps remain untreated. For their complete grinding, multiple passes of the machine along one track are required, which significantly increases the complexity, energy intensity and cost of processing pumped land.

A known method of processing zakacharny land (AS USSR No. 743613, A01B 79/00, bull. No. 24 dated 06/30.80), including plowing the bumps into the soil, characterized in that in order to improve the quality of planting residues before Using a plow, the bumps are compacted and simultaneously cut into pieces of equal sizes without separation from the underlying soil layer.

The disadvantage of this method is the high complexity, energy intensity and cost associated with cutting the ground part of the high hummocks, as well as the need for additional cutting pieces of soil after plowing.

Closest to the proposed is a method of processing pumped land (Yeltsov EI, Lopatin A.M. Mechanization of cultural works. M., Kolos, 1976, p. 128 ... 129), including rolling with cutting, grinding and plowing bumps.

The disadvantage of this method is the high complexity and energy intensity of rolling with cutting, requiring the processing of land with large plant bumps of multiple passes on one track. In addition, after grinding the previously rolled and cut mass, it is necessary to re-roll it to ensure subsequent quality plowing into the soil.

These disadvantages are eliminated by the proposed method for processing occult soil, including rolling, crushing and plowing the bumps into the soil, in which 2/3 of the height of the ground part of the bumps is initially crushed, the crushed mass is distributed between the bumps, and before being wound, the remaining lower part of the bumps is compacted together with the crushed mass .

The essence of the proposed method lies in the fact that grinding only the upper part allows you to better chop mainly the plant part of the high hummocks, mixing it with the most fertile soil, concentrated at 2/3 of their maximum height, increase productivity, reduce labor intensity, energy consumption and, accordingly, the cost of processing the pumped land. The distribution of the crushed mass between the bumps allows you to free the surface of the lower part of the bumps and to provide better deposition during compaction. Joint compaction of the lower part of the bumps together with the previously crushed mass of the upper part allows to reduce the height of the lower part of the bumps and at the same time roll the crushed mass between the bumps to minimum values, providing the subsequent high-quality plowing into the soil.

The invention is illustrated in the drawing, where figure 1 shows the characteristic structure of tall plant bumps and section profiles of the plot, showing the sequence of processing of cropped land by the proposed method.

The proposed method of processing zakachennyh lands is as follows.

Initially, 2/3 of the ground part of the high bumps 1 is crushed by a cutter 2, mounted on the base tractor 3. The cutter 2 is installed at the maximum height of the bumps using adjustable support wheels 4. After the cutter 2 passes, the crushed plant mass with soil is distributed between the bumps using a blade 6 At the maximum height of the bumps in the area of 50 ... 80 cm, the height of the crushed upper part is 33 ... 53 cm, and of the unmilled lower part - 17 ... 27 cm. The lower part of the bumps 7 is compacted together with the crushed mass distributed between them 8 Livni roller 9, whereupon the compacted mass is plowed plow 10.

Grinding only 2/3 of the height of the bumps allows the use of less energy-intensive cutters and work at high speeds. Rolling the remaining part of the bumps and the crushed mass distributed between them is carried out by a lighter roller than in the prototype method. The process of grinding, distribution and rolling can be carried out in one pass with one unit and provide the subsequent high-quality scenting.

Thus, the proposed method for processing shorted lands with a height of bumps of 50-80 cm allows to reduce the volume and increase the productivity of work on their grinding, improve the quality of plowing, reduce the complexity, energy intensity and cost of processing pumped land.
