SU950221A1 - Sower for under-crop and half-crop sowing of grasses on stubble fields - Google Patents

Description

The invention relates to agricultural machinery, in particular, to seed plots for sub-cover and half-cover sowing of grass against the background of grass, which can be used for the simultaneous sowing of seeds of forage crops (oats, barley, etc.) and perennial grasses (live grass, sweet clover, etc. .) and separate rows, and, as a rule, at different depths.

Seeds for under-cover and half-cover sowing of grass on stubble backgrounds are well known, containing bunkers for seeds of various crops, sowing machines, tubular coulters with parallelists and press rolls 13.

The disadvantage of these forks is the impossibility of applying the Individual adjustment of the depth of the coulters due to the fact that the press rollers mounted on the overall

the axles roll in small grooves and do not compact the soil in those rows where the coulters form the grooves of greater depth.

The purpose of the invention is to increase the yield by ensuring the sowing of seeds of different crops to different depths with the same depth of the coulters.

10 The goal is achieved by the fact that in the plant for sub-cover and half-cover sowing of grass on stubble backgrounds, containing bunkers for seeds of various crops, sowing machines,

15 tubular coulters with ear plugs and press rollers, part of the coulters is provided with side plates rigidly fixed on them above the lower edge of the thumb plugs with

20 by an exponential curve of bevels, and between this side plates there is a guide installed with the possibility of moving it relative to the vomer in the vertical and longitudinal directions. FIG. 1 shows a seedbed for sub-cover and half-cover sowing of gravel on stubble backgrounds, side view; in fig. 2 — node I in FIG. one; in fig. 3 is the same, top view. The mill includes two bunkers for family 1 and 2, sowing units 3 and, sem wires 5 and 6, tubular coulters 7 and 8, and a roll-in roller 9. Vomer 8 includes tubular post 10, roller 11, and two side plates 12, which are fixed above the lower edge of the neck 11 and have bevels made along an exponential curve, directed upwards in the opposite direction of the movement of the seed. The rear part of the rack -10 coulter is equipped with a bracket 13, which has slotted grooves k for fastening the guide 15 with a bolt 16. This guide is installed in the area between the plates 12 and consists of two parts: the top and bottom. A plate 17 is welded to the upper part of the tube, with the help of which the tube is attached to the bracket 13. The upper and lower parts of the tube are connected using a sleeve 18. The sealer works as follows When the sowing machines work, the seed and two seed bins are sown in parallel: the main crop (grass seeds) and sub-cover sludge half-crops (seeds of fodder) Seeds of fodder crops from the seeding apparatus 3 enter the wires 5 into this sem, then through the hollow strut of the opener 10 to the bottom of the furrow formed by the root plate 11. Shelter sem soil is due to the soil layer, a streamlined strut and of repose of the soil from the furrow walls. The roller following the coulter 9 compresses the soil over the seeds. Grass seeds from the seed meter t through the seed 6 lead into the seed guide 15, which is located in the zone between the side plates 12. The side plates are retracted, part of the moving soil, not allowing them to close directly behind the coulter, and the other part in the lower part of the bevels, they pass inside the space between the cheeks to cover the bottom of the furrow. Moreover, the amount of soil ingested goes with an increase from the beginning of the opener and periphery in the course of the opener movement. Seeds from these directors 15 are sown on the soil layer covering the furrow, due to which the depth of their embedment is smaller compared to the seeds of the sub-cover culture, which lie at the bottom of the furrow. Seeding of grass seeds occurs at the expense of covering them with a part of the moving layer of soil and due to the natural fall of soil from the walls of the furrow. The roller 9, which follows the coulter, compacts the soil above and under the sprouted seeds. The depth of seeding of herbs is adjusted by moving the guide 15 in the slots of the bracket in the horizontal plane and by displacing its lower part in the coupling 18 in the vertical direction. The lower and closest to the rack 10 openers of the position of the guide 15 provide deep seed placement into the soil, and the top and remote position from the rack 10 of the seed guide 15 provide a soft seed seal. The use of the proposed under-cover and half-cover crops for sowing on stubble backgrounds makes it possible to obtain feed in the first year of sowing and to increase the yield of feed crops per unit area by 20-251 compared to pure sowing of perennial grasses. Claims of the Invention Seed for sub-cover and half-cover sowing of grass on stubbled backgrounds, containing bunkers for seeds of various crops, sowing machines, tubular coulters with pickles and roll-in rollers, characterized in that. That, in order to increase the yield by ensuring the sowing of seeds of different crops to different depths with the same depth of the coulters, some of the openers are equipped with side plates rigidly fixed to them above the lower edge of the tips with bevels made according to an exponential curve, and between the side plates the ability to move it relative to the coulter in the vertical and longitudinal direction.
