Description

The invention relates to agricultural engineering, in particular to rollers for intrasoil compaction of previously loosened soil.

A device for intrasoil compaction of the structure of the root layer previously loosened by various tools is known, including a radial outer cutting rim located on the spokes converging in the center into the hub, with a sleeve installed through its central part, through which the axis passes, transmitting the force from the agricultural machine by means of bearing supports. At the same time, rings, attached from opposite sides and fixed in the protrusions of the cutting rim, equipped with a cylindrical hole in the center, into which the bushing with the axle enters, protect the inner region of the cutting rim from the ingress of soil elements (see GB 2371198 A class A01B 29/04 from 24.07.2002).

The disadvantage of the known device, structurally endowed with a large selection of protective rings attached to the bushing and the protrusions of the cutting rim on opposite sides of the cutting rim to protect the inner area from the ingress of soil elements, is the constant value of the inter-disc distance, which is filled with soil and clogs the entire disk battery.

A device for intrasoil compaction of the structure of the root layer previously loosened by various tools is known, which includes opposite plate-like elements compressed along a flat circular base. Pressed by an external force into the outer radially expanding surface, with a central bent inwardly of the plate-shaped element, a short bushing through which the axis passes, while the closed hollow discs of the plate-shaped elements expand radially, creating a sharp edge of the disk roller (see US 1444224 class A01B 29/04 from 06/02/1923).

The disadvantage of the known device of plate-shaped two opposite hollow disks closed on a flat circular base, radially expanding, creating a sharp edge of a disk roller, held on an axis through a short sleeve curved inwardly of a plate-shaped element, is a constant between the disk space filled with soil particles sliding along the convex surface from a sharp edge to sticking to the walls of the disc, which contributes to clogging the entire disc battery.

Known is a device for intrasoil compaction of the structure of the root layer previously loosened by various tools (see Soil compactor. PLUTO. Type OSTROJ 2.1-2.9 m. Model 2001. Catalog of spare parts for OPALL-AGRI machines, sro. Page 4 www.opall-agri.cz), including a solid disc with a wedge-shaped rim, through which, in the form of a deltoid (Steiner curve), a convex hole is made, consisting of conjugate figures, circles touching the disc rim along the tops of the deltoid, and depressions, constructed by the deltoid equidistances through the sides of the circles touching the rim of the disk. The valleys of the through hole along the equidistant line are equidistant from the center of the disk, located on a concentric circle, the protrusions of the solid disk conjugated along the border of the valleys of the through hole have a convex shape, evenly spaced along the rim of the solid disk, through the protrusions of the solid disk along the lines of concentric circles, pairwise through holes pass through the protrusions of the solid disk along the lines of concentric circles, closest to the center of the disc, for attaching spacers, on opposite sides of the solid disc, farther to the center of the disc, to reduce mass while maintaining the balance of the disc.

The disadvantage of the known device, attached to bearing supports in the middle and at the edges, spacers spaced across the width, compacting the soil with a wedge-shaped surface of the disc rims, with a through hole in their centers, having a convex shape, previously loosened by different working bodies of the structure of the root layer, is the wedge-shaped shape of the sealing surface that penetrates excessively deep into loose soil.

The closest in technical essence and the achieved result to the claimed invention is the device for intrasoil compaction of the structure of the root layer previously loosened by various tools (see Lemken Operation Manual. Heavy ring roller. Variopak. RU-2 / 05.01 LEMKEN GmbH & Co. KG Weseler Strasse 5 , D-46519 Alpen / Postfach 11 60, D-46515 Alpen. Internet: http://www.lemken.com). Includes, sealing rings with a rim profile of 30 or 45 degrees, the rings are radially equipped with protrusions on which flat lugs are located along the line of concentric circles, through which holes are made along the line of concentric circles for attaching spacers on opposite sides connecting the sealing rings to the battery, the length of which can be lengthened or shortened by screwing and unscrewing rings, batteries equal in number of rings are bolted on opposite sides of the pipe attached to the tractor hitch, with each battery base attached to a three-sided protrusion resting on a bearing assembly attached to the pipe held by the frame, attached to the tractor.

The disadvantage of the known device is the wedge-shaped form of the sealing surface, which penetrates too deeply into the loose soil.

The problem solved by the claimed invention is the technological possibility of increasing the subsurface compaction of the previously loosened soil by two opposing cup-shaped annular plates, closed on the disk by a spacer with a convex rim by axial compression, forming hollow seal rings with a radial protrusion, and making a penetrating conical crack of variable width in the soil.

To solve this problem, curved cup-shaped plates are used on a flat base in the center of a circle of which a through hole is made in the shape of a deltoid, the edges of the base are raised and bent outward parallel to the base to form a flat circular surface along the periphery, radially protruding outward with a sharp edge, curved cup-shaped plates in pairs are closed by circular surfaces into hollow sealing rings with a sharp projection and have a spacer disc fixed inside with a convex rim shape and flat ends, and the through hole in the shape of the deltoid of the spacer disc and the hole in the hollow sealing rings are displaced coaxially through the through holes along concentric spacer discs are screwed to the circles of the hollow seal rings, forming compaction rollers with the hollow seal rings, assembled through through holes on the concentric circles of the rollers for compaction with long spacer pipes into the battery, which with short pipes-p The rods are fixed on the bearing discs of a triangular convex-concave rim, which are located at opposite ends of the solid axis, which transfers the load through self-aligning bearings to the pipe, to which the bearing discs are located with a gap.

The presence of the sign "completed solid axis" allows to rotate hollow seals with a radially expanding surface and a sharp radial edge, which are screwed on spacer discs, hollow seals with a radially expanding surface and a sharp radial edge, forming conical cracks of variable width penetrating in depth in the compacted soil layer.

The presence of the feature "on a solid axis, bearing disks are fixed with an interference fit, rotating with the axis, in self-aligning bearing supports, inside the bearing pipe, with gaps to the ends of the bearing pipe, in the form of convex-concave equidistant deltoids (Steiner curve)", allows for the proposed shape of bearing disks , ensure strength and stability. On the tops of the bearing discs, peripherally and perpendicularly there are cylindrical grooves with through coaxial holes, on both sides cylindrical short spacers are pressed into the cylindrical grooves, attached by bolts and nuts to hollow sealing rings on spacer discs forming a battery, compressed together through spacer pipes with a bolt and a nut, on both sides of hollow sealing rings on spacer discs, into an asymmetric battery relative to the bearing discs. One long side is made with a cantilever protrusion, the uniform action of the axial load creates a significant force on the long battery, creating a radial force on the disk, driving the axle on self-aligning bearing supports to bend of a variable radius.

The presence of the feature "rings are hollow seals assembled on a disk spacer of pairwise opposite symmetrical cup-shaped plates, with externally curved and radially expanding outward surfaces, adjoining each other along the plane create a sharp edge, the concave projections of the plates form a plane in the center of which a through hole is made, outlining the contour an equilateral triangle, in the form of convex-concave deltoid equidistant curves (Steiner curve), outside the concave sides of the through hole along the lines of concentric circles, through holes are made for attaching cup-shaped plates on both sides of the spacer disc, screws and bolts with nuts, along long spacer pipes , the spacer disc is made with flat ends and a convex rim. Through the center, perpendicular to the flat ends of the spacer disc, a through hole is made congruent to the shape, convex-concave equidistant deltoid, holes of the cup-shaped plates, on both sides of the spacer disc along the lines of concentric circles, through holes and recesses are made, coaxial to the through holes of the cup-shaped plates, in the center through holes are made in the recesses of the spacer disc, through which the cup-shaped plates are fastened with screws and bolted joints through long spacer pipes into the batteries, "allowing to lengthen or shorten the length of the batteries. Batteries of equal number of assembled sealing rings are fastened with short spacer pipes on convex-concave bearing discs, increasing the strength of the sealing ring by hollow axial compression by bolts and nuts, by means of pipe protrusions of short and long spacers.

The inventive device, a roller for intrasoil compaction, consists of 27 hollow rings 13 of seals assembled in pairs from opposite cup-shaped plates 1, with externally curved surfaces and radially expanding outward surfaces, adjoining each other along plane 2, create a sharp edge 11. Concave projections 3 of the plates form a plane 4, in the center of which, a through hole is made, outlining the contour of an equilateral triangle 5, in the form of convex-concave deltoid equidistant curves (Steiner curve). Outside the concave sides of the through hole 5, along the lines of concentric circles, through holes 6 are made for attaching the cup-shaped plates 1 on both sides of the spacer disc 8, screws 9 and bolts 15 with nuts 16, along the long spacer pipes 14. The spacer disc 8 is made with flat ends and a convex shape of the rim, through its center, perpendicular to the flat ends of the spacer disk 8, a through hole is made congruent to the shape of 5, convex-concave equidistant deltoid (Steiner curve). The openings of the cup-shaped plates 1 coincide with the through holes 10 and the recesses 12 on both sides of the spacer disc 8, located along the lines of concentric circles. Through holes 10 are made in the center of the recesses 12 of the spacer disc 8, through which the cup-shaped plates 1 are fastened with screws 9 and bolted 15, 16 connections through long spacer pipes 14 into the batteries. Extending or shortening the length of the batteries by screwing or removing the hollow 27 rings 13 of the seals held by a bolted connection 15 and 16 with long spacer pipes 14. The batteries, equal in the number of assembled rings of the battery seals, are fixed with short spacer pipes 24 on the bearing discs 17 of a convex-concave shape, located at opposite ends 22 of the solid axis 21, transferring the load from the inside to the pipe 25, through the bearing supports 28 self-aligning inside the pipe 25, while the bearing discs 17 are located on the axis 21 with a gap (a gap between 17 and 25) to the ends of the pipe 25. Pipe 25 held by frame 26 is attached to the tractor.

The roller for subsoil compaction works as follows. Assembled in pairs, from opposite cup-shaped plates 1, compressed by screws 9 on both sides of the spacer disc 8, a hollow sealing ring 13, with a sharp edge 11, presses the previously loosened soil, with an increased compaction effect, known from the literature as "DD effect". The essence of the "DD effect" is the formation of a dense sole under the hollow sealing ring 13, in which, from the sharp edge 11, a vertical, expanding upward and deeply penetrating crack is formed, through which moisture and air can penetrate into the lower layers of the soil, the compacted structure is increased deeper soil. Hollow ring seals 13 are sparsely located, at a distance of long spacer pipes 14, through which, by connections of bolts 15 and nuts 16, through hollow ring seals 13, they are assembled into a battery, the length of which can increase or decrease depending on the number of hollow ring seals 13 collected in a battery ... The fewer hollow seals of rings 13 are included in the battery, the more force from each disk penetrates into the previously loosened soil, and at a greater depth a layer of soil of increased density is formed, which keeps the loose soil horizon from precipitation, in which the root system grows. Between the hollow seals of the rings 13 pressed into the previously loosened soil, the space is filled with soil particles sliding along the outer sides of the bowl-shaped plates 1, outlining the contour of an equilateral triangle 5 up to the through hole, in the form of convex-concave deltoid equidistant curves (Steiner curve). Triangular contour 5 with convex-concave sides acts on soil particles, destroying their structure and, under the action of centrifugal forces, forcing soil particles to sift through between the disc space onto the soil surface, into the soil ridges formed after the passage of the batteries. The batteries are fastened with short spacer pipes 24 to bearing disks 17 of a convex-concave shape, located at opposite ends 22 of the solid axis 21, made of an elastic material. The elastic axes under the action of the load change the angle of inclination, which leads to a change in the angle of inclination of the entire battery, as well as of each hollow ring seal 13, the sharp edge 11 of which forms a wide channel from the outside of the crack, deeply penetrating in depth for each hollow ring seal 13. Axis 21 through self-aligning inside the pipe 25 bearing supports 28, holds the bearing discs 17 with an interference fit on the protrusions 22, with a gap (a gap between 17 and 25) to the ends of the pipe 25. The pipe 25, held by the frame 26, is attached to the tractor and is adjusted according to the immersion depth in the earlier loosened soil, hollow O-rings with 13 tractor hitch.
