SU1371567A1 - Furrow opener for inclined application of fertilizers to soil - Google Patents

Abstract

This invention relates to agriculture. The invention is a reduction in traction resistance and an increase in the accuracy of fertilizer application. The opener contains a cable 1 with a window 4, in the zone of which parallel disks 5 are placed on the hub, made in an Archimedes spiral. Overlapping knives 7 are installed in the gap between the discs. The gap is in communication with the window 4. When the coulter moves, the disks 5 are buried in the soil. The folding knives 7 lie on the surface of the soil and turn around, closing the gap between the discs 5. Then from pipe 1, fertilizer is fed through the window 4 through the gap 4. After passing the lowest point in the soil, the discs begin to emerge from the soil. At the same time, the knives 7 open the gap and the fertilizers enter the soil. 4 il.

The invention relates to agriculture, in particular to coulters for fertilizing the soil.

The aim of the invention is to reduce traction resistance and improve the accuracy of fertilizer application.

FIG. 1 shows the proposed opener in longitudinal section, general view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a diagram of the layout of fertilizers in a patchy layer along the trail of coulters behind; in fig. 4 is a diagram of the fertilizer layout in the arable layer by the movement of the coulter.

The opener consists of a vertical duct 1, the lower end of which is bent at an angle of 45–60 ° to its axis and rotatably equipped with a hub 2 fixed by a cork nut 3, and a window 4 is made at the bottom of the bent end of the conduit I at the site of hub 2 The hub 2 on the side of the window 4 is equipped with a fertilizer device made in the form of two discs 5, the cavity between which is continuously communicating with the window 4. Each of the discs 5 is made in the form of one or two (as shown in the drawing) turns of the Archimedes spiral, and in the slits of the disks 5 between their edges The folding knives 7 are mounted along the perimeter on the axis x 6. The drawing shows an arable layer of soil 8 and fertilizer bands 9. Knives 7 are set in the direction of rotation of the disks 5.

Centurion works as follows.

When the agricultural unit with the tukul spruce moves along the arable field of the soil 8, the disks 5 are angled up; 1 they plow into the arable soil 8 up to the limits of the cork nut 3 of the pipeline 1. The disks 5 rotate in the usual way on the hub 2, with their profile under the surface of the arable layer of soil 8. In this case, the folding knives 7, when the edges of the disks 5 enter the soil 8, lie on the soil surface 8 n and under the influence of its resistance turn on axis 6 and close the gap between the disks 5. And so successively one after another and pressing each other knives 7 p

the movement of the disks 5 closes the gap between them, eliminate clogging it with earth. Next, the knives 7, deepened in the direction of movement of the disks 5, cut the soil 8 to the lower point of rotation. At the same time, fertilizers 1, for example granulated or liquid, are metered into the conduit 1, which through the conduit 1 and through its window 4 continuously enter the gap between the disks 5 and, continuing to fall, enter the bottom

0 part. At this time, continuing its rolling, the disks 5, after passing the lower point, begin to draw their profile from the soil. The knives 7, both due to their weight and due to the resistance of the soil 8, rotate on axles 6 and open the gap between the disks 5. Fertilizer from the cavity of the disks 5 at the lower point through opening the knives 7 flow down into the soil 8 and the disks 5 with knives 7 roll back further along the course of the movement, he constantly left behind him, according to his profile, a strip of fertilizers 9.

When the disks 5 are rolling around from their minimum radius of the Archimedes spiral to the maximum along the direction of movement, their profile forms a gradual deepening of the approach from the minimum to the maximum, forming

5 layer close to the sloping straight line, along which spreads the fertilizer strip behind it 9.
