Abstract

The utility model relates to agricultural engineering, mainly to sowing implements, in particular for sowing grain crops using zero technology with the simultaneous application of liquid complex fertilizers. The result is achieved due to the fact that behind the fertilizer duct and furrow formers there are two symmetrically located side harrows with C-shaped bent elastic leashes connected by a jumper and hinged to a common axis inserted into the elongated hole of the stand and fixed in various positions in height by a nut. Combined anchor coulter to the seeder for zero technology, containing a chisel, a stand with furrow formers symmetrically installed on it in the form of side plates 6 mm thick, the rear lower working edges of which are located below the toe level up to a seed duct installed on the rear side of the rack, and a fertilizer duct is installed behind the seed duct, which is a tube that splits into two tubes of smaller cross section, fixed on the rear ends of the furrow formers so that their ends are brought out beyond the rear lower working edges of the furrow formers, and behind the fertilizer duct and furrow formers are installed two symmetrically arranged lateral harrows with C-shaped bent elastic leashes connected by a jumper and hinged to a common axis inserted into the elongated hole of the post and fixed in various positions in height by a nut.

Description

The utility model relates to agricultural engineering, mainly to sowing implements, in particular for sowing grain crops using zero technology with the simultaneous application of liquid complex fertilizers.

Known anchor opener grain seeder SKP-2,1 [Seeder-cultivator grain fertilizer for strip sowing SKP - 2.1. Operation manual SKP-2.1 00.00.000 RE. - with. 41-42. Electronic resource. http://www.agrozakup.ru/img/file/rukovodstvo_polzovatelva_sevalka_omichka_skp_2_l.pdf. (Date of access: 10/26/2021)], which includes a rack made of sheet material, a chisel made of wear-resistant steel, and a seed tube.

The disadvantage of this anchor coulter is the irrational mutual arrangement of the applied fertilizers and the sown seeds, leading to incomplete absorption of fertilizers as the plants grow.

The closest analogue to the claimed is a combined anchor opener [Author's certificate RU patent No. 207073, IPC class. А01С 7/20, А01В 5/08, 2021], containing a chisel, a stand with furrow formers symmetrically mounted on it in the form of side plates 6 mm thick, the rear lower working edges of which are located below the level of the toe of the chisel, a seed tube installed on the back of the stand, and a fertilizer duct is installed behind the seed duct, which is a tube that splits into two tubes of a smaller section, fixed on the rear ends of the furrow formers so that their ends are brought out beyond the rear lower working edges of the furrow formers.

The disadvantage of this design is the low quality of work due to the lack of the function of falling asleep applied fertilizers and sown seeds with soil.

The technical result of the utility model is to improve the quality of work due to the emergence of a new function of falling asleep applied fertilizers and sown seeds with soil.

The technical result is achieved due to the fact that behind the fertilizer duct and furrow formers there are two symmetrically located side harrows with C-shaped bent elastic leashes connected by a jumper and hinged to a common axis inserted into the elongated hole of the stand and fixed in various positions in height by a nut.

The specified set of essential features provides the inventive combined anchor coulter with new properties that are different from the prototype.

Thus, the claimed features of the utility model meet the criterion of "novelty".

In FIG. 1 shows a diagram of a combined anchor coulter for a seed drill for zero technology, side view, in Fig. 2 - the same, rear view.

A combined anchor coulter for a seeder for zero technology, containing a chisel 10, a stand 6 with furrow formers symmetrically installed on it in the form of side plates 9 6 mm thick, the rear lower working edges of which are located below the level of the toe of the chisel, a seed tube 3 installed on the rear side of the stand, and a fertilizer duct 2 is installed behind the seed duct, which is a tube that bifurcates into two tubes 12 of smaller cross section, fixed at the rear ends of the furrow formers so that their ends are brought out beyond the rear lower working edges of the furrow formers, and behind the fertilizer duct and the furrow formers there are two symmetrically located side harrows 1 with C -shapedly curved elastic leashes 5, connected by a jumper 4 and hinged to a common axis 8, inserted into the elongated hole 7 of the rack and fixed in various positions in height by a nut 11.

Before work, the combined anchor coulters of the claimed design are installed on the seeder for zero technology. The coulter works as follows.

When performing a technological operation, the chisel 10 cuts a slot in the soil, Fig. 1, zone a , to a set depth and discard it on both sides of the coulter, forming rollers on the field surface, fig. 1, zone b. This creates a dense seed bed. Seeds are fed through the seed tube 3 to the sowing bed formed by the chisel 10. The furrow formers 9, while symmetrically cut two narrow grooves on both sides of the seed bed below the level of the toe of the bit 10. Liquid complex fertilizers are fed through the fertilizer pipelines 2 into the grooves formed by the furrow formers 9, and are applied into the soil below the location of the seeds, Fig. 1, zone with. The depth of fertilizer supply relative to the level of the seeds and the offset away from the axis of the row is set by selecting the appropriate coulter size depending on the crop being sown, row spacing and soil type.

Harrowers 1, pressed against the field surface by the force of elasticity of the C-shaped elastic leashes 5, shift the soil from the side rollers onto the coulter track, fill the grooves with fertilizers, forming a layer of soil between the fertilizers and the seeds of Fig. 1, zone d and form a layer of soil of the required thickness over the seeds, FIG. 1, zone e.

The use of a combined coulter of this design when sowing by zero technology improves the quality of work.
