Abstract

FIELD: agricultural and forest engineering.

SUBSTANCE: working tool has horizontal hollow cylinder and hole making members designed for pressing seeds into soils. Cylinder with hub positioned inside it is composed of two telescopically connected parts. Each part of cylinder has side with pins and shell mounted thereon. Hole making members are fixed to shell. Side of one cylinder part is connected to hub. Side of other cylinder part is mounted on bushing positioned on hub for displacement along and around it for alteration relative arrangement of hole making members fixed on adjacent shells. Each of said shells is made in the form of rim with ring perpendicularly welded therein and provided with a number of openings for attachment to cylinder sides. A number of openings are formed circumferentially of shells for uniform location and attachment therein of hole making members by means of pins welded to hole making member bases and nuts positioned at inner side of shells. Hole making members fixed on adjacent shells are adapted for positioning one opposite another or in circumferentially offset relation with respect to one another, and also for altering distance between rows of hole making members. Hole making members fixed on adjacent shells are located in circumferentially offset staggered arrangement.

EFFECT: improved quality of seed embedding and, accordingly, provision for producing of good young crop, enhanced growth and development of plants.

Description

The invention relates to agricultural and forestry engineering, in particular to the working bodies, planting seeds in the soil. Known close-up working bodies that are used for backfilling sown seeds with soil, as well as for its compaction. These include screwdrivers and rollers of various designs: cylindrical, with a concave rim, pairwise mounted rollers with a conical rim on the horizontal axes, cylindrical on the inclined axes, etc. (Sviridov L.T. Technologies, machines and equipment in forestry: Textbook / L.T.Sviridov, V.I. Vershinin. - Voronezh: VGLT - 2002. - S.130-131).

Their disadvantage is that they produce a continuous seeding of seeds into the soil without performing additional technological operations that contribute to creating conditions for better moisture accumulation and development of plants.

Known sowing combined unit with coulters and zagortachki made in the form of rollers, on the surface of which are mounted soil deformers in the form of dihedral wedges. When the unit is operating, discrete troughs are created on the field surface by the coulter, seeds are sown in them, which are then crushed by an ice rink, which follows the coulter, as a shortener. The hollows left after this contribute to the concentration of moisture in them in close proximity to the sown seeds, which ensures their germination and rooting of plant growth with a limited amount of rainfall (RU 2226324 C1, class A01B 49/06, 08/28/2002).

The disadvantage of this design is its complexity and the presence of several nodes (skating rink with openers and skating rink - shorting) for the operation of the formation of discrete moisture-collecting troughs and seeding them sown seeds.

A device is known for intermittent sowing of seeds and the formation of moisture-accumulating depressions in the soil, which includes a hole-forming working body made in the form of a cylinder with hole-forming elements uniformly radially located on its rim, which press seeds into the soil and simultaneously form water-collecting depressions (RU 2240667 C1, cl A01B 49/06, 03/18/2003). The hole-forming working body of this device can be considered the closest analogue of the invention.

A drawback of the design of this working body is that it presses and seals discontinuously sown seeds into the soil, with the simultaneous formation of moisture-collecting recesses, only in one row with evenly distributed seeding places, eliminating the possibility of seeding adjacent rows in crops with a mutually dependent arrangement of sowing places.

The objective of the invention is to provide high-quality planting in the soil of plant seeds sown discontinuously in several adjacent rows according to various schemes, with the simultaneous formation of water-collecting recesses (holes) at the seeding sites.

The technical result in solving the problem of the invention is achieved by the fact that in the known working body for seeding intermittently sown seeds in the soil, including a horizontal hollow cylinder and hole-forming elements pressing into the soil, the cylinder has a hub located inside it and is made of two telescopically connected parts, each of which has a sidewall with studs and a shell mounted on it, on which hole-forming elements are fixed, while the sidewall of one part of the cylinder is connected to the hub, and okovina other part of the cylinder is mounted on a sleeve disposed on the hub to move along and around it to change the mutual location lunkoobrazuyuschih elements mounted on the sleeve adjacent. And also the fact that each shell is made in the form of a rim with a ring perpendicularly welded inside it, having a number of holes for attachment to the cylinder sides. A number of holes are made around the circumference of the shells for evenly locating and attaching hole-forming elements therein. Hole-forming elements are fixed in the holes on the shells by means of studs welded to the bases of the hole-forming elements and nuts located on the inside of the shells. The hole-forming elements mounted on adjacent shells are arranged to be opposite to each other or offset around the circumference, as well as with the ability to change the distance between the rows of hole-forming elements. Hole-forming elements mounted on adjacent shells are displaced around the circumference with staggered placement.

Figure 1 shows the working body for incorporation into the soil of intermittently sown seeds, in a section, a front view; figure 2 is the same working body, side view.

The working body for intermittently sowing seeds in the soil contains a sliding cylinder and shells with hole-forming elements.

The sliding cylinder consists of two parts - one in the form of a cylinder 1 with a sidewall 2 welded to the hub 3, and the other - in the form of a cylinder 4 with a sidewall 5 welded to a sleeve 6 located on the hub 3 and having the ability to move along and around the hub 3 . Fixing the sleeve 6 when it is rotated or moved by a bolt 7.

The shells 8 and 9 are made in the form of rims with rings 10 and 11 perpendicularly welded inside them, having holes for mounting on the studs 12 of the sidewalls 2 and 5 of the sliding cylinder. Around the circumference of the shells there are a number of holes for evenly positioning the hole-forming elements 13 by means of studs 14 welded to the bases of the hole-forming elements 13 and nuts located on the inside of the shells.

To perform the process, the proposed working body is installed on the shaft 15 and rolls along the surface of the soil, seeding intermittently sown seeds by pressing them into the soil with hole-forming elements 13, which simultaneously create moisture-collecting cavities.

Ultimately, the implementation of the technological process of seeding intermittently sown seeds in the soil by the proposed working body will provide good seed germination, growth and development of plants.
