SI21870A - Tractor trailer for breaking up and fertilizing soil - Google Patents

Abstract

The tractor trailer for breaking up and fertilizing soil, which is particularly aimed at cultivating several years old orchards and vineyards, improves the breaking up and fertilizing of soil, particularly in orchards and vineyards, where a smaller tractor power compared to the existing one is required while resulting in a very similar effect of breaking up along with an improved quality of fertilizing. The tractor trailer according to the invention is made from a known tractor trailer (1) which features a vertical support (2) behind it, while on its lower end looking back, this means in the opposite driving direction, there is a console support (3), where on the trailer (1) there is a Cardan link (4), which via a belt drive (5) drives the fan (6), located on the support (2) and is aimed at injecting fertilizer from the container (16) into the soil under pressure and is at the same time also a base (7) of the break-up elements (8), located on the lower side of the console support (3).

Description

Tractor attachment for soil tillage and fertilization

The subject of the invention

The subject of the invention is a tractor attachment for soil tillage and fertilization, and is especially intended for the cultivation of perennial orchards and vineyards.

A technical problem

A technical problem solved by the invention is how to improve the cultivation and fertilization of the soil, especially in orchards and vineyards, with a tractor attachment that will require less tractor power than known such attachments at about the same! the effect of loosening and improving the quality of fertilization.

The prior art

Knives are known as tractor attachments, which are made of knives and plows, preferably two, because of the predicted power of the tractors. Some tillers have built-in fertilizer devices that distribute fertilizer over the soil surface in metered quantities.

There are two disadvantages to these embodiments: The first disadvantage is that loosening with this type of ripper requires relatively high tractor power. Another disadvantage is that fertilization is done by spraying fertilizer over the soil surface. Therefore, the penetration of fertilizer into the depths of the earth where it is

28680.doc / VIII-04 / D-34-Vr rooted for a long time. Many times the fertilizer gets deep into the roots only the next year, when the harvest is already harvested.

Therefore, there is a need to improve both features of this tractor attachment.

The solution to a technical problem

The descriptive technical problem is solved by the attachment according to the invention such that at least one loosening element is made with a vibrating slanting slant that raises a part of the earth approximately in a vertical direction, thereby also reducing the required power of the loosening tract. Another feature of the present invention is that the fertilization is carried out by blowing the fertilizer into the previously loosened soil at root depth at elevated pressure and also dispersing through cracks in the soil due to the elevated pressure to immediately reach more roots. This makes the effect significantly greater in terms of the amount of fertilizer applied and also faster.

The essence of the invention will be explained in more detail below with a description of an embodiment and the accompanying drawings, in which FIG. 1 is a schematic side view of the device according to the invention.

The tractor attachment for loosening and fertilizing the soil is derived from the three-point tractor attachment 1 of categories 2 and 3, on which the upright carrier 2 is made immediately behind it, and at its lower end back, i.e. in the opposite direction of travel, the cantilever carrier 3 is directed. At the connection 1 there is a cardan connection 4, which is driven by a belt drive 5, the fan 6, which is mounted on the carrier 2, and at the same time the outlet 7 of the loosening elements 8, which are mounted on the underside of the cantilever of the carrier 3.

28680. doc / VI I l-04 / D-34-Vr

The device according to the invention comprises at least one loosening element 8, preferably two. Depending on the need for the rate of cultivation and the available power of the tractoi and the type of agricultural land, several loosening elements 8 may be installed on the device according to the invention.

Each loosening element 8 is made vertically from the cantilever bracket 3 downwardly directed knife 9, made in the shape of an L. Approximately at the free end of the transverse arm 10 of the knife 9 there is a pivotably mounted loosening plate 12 in the bearing 11, which lies above the arm 10 and partially encloses knife 9. The rake plate 12 is connected via a rod 13 to an eccentric pin 14, rotated by a deflection 7 driven by a tractor engine through a PTO connection 4. By pivoting the pin 14, the shaft 13 pivots axially to rotate the mounting plate 12 around the bearing 11 to be relatively small, thereby causing the plate 12 to lift the ground and thereby loosen it.

A cantilever assembly 15 is also mounted on the cantilever carrier 3. This assembly 15 ^ consists of: a fertilizer hopper 16, to which an outlet opening 17 is provided with a fertilizer dispenser 18. The dispenser 18 is preferably designed as a paddle wheel driven through a belt drive 19 with an adjustable gear ratio, whereby the drive 19 receives driving power from the toothed wheel 20, which is pivotally mounted on the carrier 3 and rolls over the cultivated soil. Its speed of rotation is proportional to the speed of movement of the tractoi with the attachment of the invention to the ground, which it loosens and fertilizes. This achieves a proportion between the travel speed of the connection of the invention according to the earth and the amounts of fertilizer flowing from the reservoir into the earth. The user determines the amount of fertilizer per displacement unit by shifting the drive shaft 19. From the dosatoi 18, the fertilizer tube 21 is guided by the knife 9 to its knee with a cross arm 10 and below the splitting plate 12, where the outlet opening 22 for the fertilizer outlet is located.

28680.doc / VIII-04 / D-34-Vr

On the upright bracket 2 there is a fan 3, from which a tube 23 flows and is connected to the fertilizer tube 21, preferably just before the outlet opening 22. This expels the fertilizer from the opening 22 at elevated pressure, thereby spreading the fertilizer. into a larger space of previously loosened soil.

At the rear of the cantilever bracket 3, an alignment roller 24 is provided to align the surface of the earth and also to adjust the depth of soil loosening by loosening elements 8. The alignment roller 24 extends about the entire width of the attachment of the invention and is seated on a shaft 25 which is rotatable by using a hand screw 26.

In a preferred embodiment, two loosening elements 8 are provided on the connector according to the invention, with both elements 8 supplying the fertilizer manifold in a pressurized air beam.

It will be appreciated that one of skill in the art may, on the basis of knowledge of the description of the invention and its embodiment, design other embodiments without circumventing the features of the invention as defined in the following claims.
