RU183148U1 - COMBINED COWLER FOR DIFFERENT SEEDING AND FERTILIZER SEEDING - Google Patents

Abstract

The utility model relates to agricultural machinery, in particular to devices for sowing and fertilizing. The combined coulter for multilevel sowing of seeds and fertilizing includes a stand with a coulter in the form of a chisel, a fertilizer duct with a sealing plate, two seed guides, rigidly fixed between the expanders and mounting plates, and installed forwardly inclined in the direction of movement of the coulter.

The coulter works as follows: when the coulter is deepened, the chisel cuts a groove in the soil into which mineral fertilizers are introduced through the piping to a predetermined depth, then two grooves cut through the extenders to the right and left, into which two-line sowing of the main crop is carried out through the seed guides, and the fertilizers are embedded in the soil is lower with respect to seed strips.

The use of this coulter will allow for sowing when combining fertilizing operations below two-line sowing of seeds. This arrangement of seeds and fertilizers contributes to an increase in the yield of grain crops due to the implementation of different depth fertilizing and two-line sowing of seeds, which increases the efficiency of fertilizer use and the area of plant nutrition. The coulter design provides the possibility of two-row sowing with or without fertilizer.

Description

The utility model relates to agricultural engineering and can be used in sowing machines, in particular to combined coulters for different depths of applying bulk mineral fertilizers with simultaneous two-row sowing of grain crops.

A seeder opener is known (Utility Model Patent No. 139420, 04/20/2014, IPC A01C7 / 20), containing working elements connected by an arm and mounted at an angle to each other in the horizontal plane in the direction of movement and at an angle of heel in the vertical plane, seed guides, racks made integral with the working elements, on the racks on the rear side in the lower part there are cutouts with a convergence angle directed forward, each working element is made in the form of a plate with a pointed toe and a straight profile of the lower edge, with on Cut-outs are made on the right side of the rectilinear profile of the lower edges of the struts, tap guides are rigidly fixed in the upper part of the working elements, the straight profiles of the lower edges of the working elements are located below the straight profiles of the lower edges of the racks.

The disadvantage of this design is that this coulter is multi-link, which leads to its increased metal consumption, design complexity and energy consumption, as well as low reliability of the sowing process.

The closest in technical essence to the claimed technical solution is “Combined opener for multi-level sowing of seeds and fertilizing” (Utility Model Patent No. 130780, 08/10/2013, IPC А01С 7/20). The combined opener for multi-level sowing of seeds and fertilizing consists of a stand with a holder, a chisel made in the form of a wedge, a seed tube, a piping with expanders, in the form of two wedges for fertilizing.

The disadvantage of this coulter is not high crop yields.

The technical result of the proposed utility model is to increase the yield of crops due to the implementation of two-line sowing of seeds and fertilizing at different depths, which increases the uniformity of seed distribution over the nutrition area and the efficiency of fertilizer use.

Combined opener for multi-level sowing of seeds and fertilizing, includes a stand with a wedge-shaped chisel, two mounting plates rigidly connected to the stand, a fertilizer line, two seed guides, and expanders installed behind the stand to the right and left of the bit, while the extenders are fixed in the lower part of the manifold a sealing plate, and seed guides are rigidly fixed between expanders and mounting plates for symmetrical sowing of seeds relative to fertilizers introduced into the furrow cut by the wedge, and the seed raviteli is inclined forward in the direction of movement of the opener.

The technical solution is illustrated by drawings, where in FIG. 1: shows a general view of the opener and a rear view; FIG. 2. The scheme of two-line sowing and placement of fertilizers by the opener is shown.

The proposed combined opener for a multi-level sowing of seeds and fertilizing is a prefabricated design including: 1 - a wedge-shaped chisel for forming a furrow; 2 - mounting plates connected by a welded joint to the rack - 3; guidebook - 5; and two seed guides - 4, rigidly fixed with mounting plates - 2 and two expanders - 6 and are installed with an inclination forward in the direction of movement of the opener. To avoid contact between fertilizers and seeds, a sealing plate -7 is installed in the lower part of the fertilizer line, the task of which is to fill the fertilizer with soil.

Combined opener for multilevel sowing of seeds and fertilizing works as follows.

When moving across the field, a wedge-shaped bit - 1 cuts a groove in the soil into which fertilizer is fed through the fertilizer pipe 5 to a predetermined depth, a sealing plate installed in the lower part of the fertilizer pipe - 7, covers the fertilizer with soil. Expanders - 6 located on the right and left sides of the bit form two grooves for seeds, the bases of which are located higher relative to the strip of mineral fertilizers introduced into the soil. Seeds from the sowing apparatus through the seed tubes and seed guides - 4 enter the grooves and are fixed in rows, providing two-line sowing. For high-quality placement at a given depth of sowing and fixing of seeds in the groove, seed guides - 4 are installed in expanders with an inclination forward in the direction of movement of the coulter.

The use of a combined coulter will allow combining two technological operations in one pass of the sowing unit: introduction of a starting dose of mineral fertilizers and sowing of grain. Moreover, fertilizers are applied deeper than the seeds, which are sown symmetrically on the sides, which eliminates a chemical burn of the seeds. This placement of fertilizers relative to two-line sowing of seeds contributes to the active development of the root system during their growing season, providing increased germination and yield of crops.

The coulter design provides the possibility of two-row sowing with or without fertilizer.
