Abstract

The object of the present invention concerns a turn-wrest plough which realizes the coupling of coulters (1) to the plough shares (4D and 4S) thereby forming a ground working element. Said coulters (1) being employed to work the sub-soil at a level directly beneath the working plane of the plough shares (4D and 4S). One or more of said ground working elements may be mounted on a composable frame (T) with a reversible, oleodynamic tool-carrier (P) that may be connected to a tractor.

Description

"A REVERSIBLE, PREPARING, PLOUGHING ANCHOR"

The present invention concerns a revrsible, preparing, ploughing anchor which, in one single compact, performs th preparing of the ground at a depth variable from 60 to 70 centimeters and, at the same time, the following ploughing at variable depth.

Recent researches in the field of improving the farm pro¬ ductivity have found out that the actual ploughing system does not respond to the needs of the fertilization of the ground. With the conventional plough, the plough-share cut the ground and the depth it leaves a smooth and rammed dow layer that does not allow the filtering of the rainwater and the raising again of the moisture during dry spells, with a consequent lack of nourishment to the roots of the plants .

Furthermore, the turning over of the ground causes, in the ploughed furrow, the deposit of the fertilized and mature layer in depth and the presence, on the surface, of the dr earth. The latter requests a further feeding with fertiliz ing substances for becoming fertile.

At present, a more rational and efficient ploughing system may be obtained by means of different means used in succes sion, for: - preparing the ground at a depth variable from 60 to 70 centimeters, with anchor-ploughs;

- a following ploughing at variable depth that allows to leave the mature and fertilized layer of earth on the surface of the ground.

It is the aim of the present invention to realize a more rational and efficient ploughing in one single compact. The aim set forth is reached by means of a reversible, prepar- ing, ploughing anchor with, in one single compact, performs the preparing of the ground at a depth variable from 60 to 70 centimeters, and at the same time the following plough¬ ing at a variable depth.

The object according to the present invention will be ex¬ plained more in detail hereinbelow according to the enclos¬ ed drawing, in which some preferred embodiments are shown:

figure 1 shows a lateral view of e reversible, preparing and ploughing anchor, having four parallel ele¬ ments.

Figures 2 and 3 show respectively a lateral and back view of a complete element.

Figure 4 shows a partial view of an adjustable connection variant of the components of one element.

SUBSTITUTE SHEE • # •/ • • • Figure 5 shows a variant of a ploughing, non-reversible semi-anchor.

Figure 6 shows an exemplifying lateral and back view of a specific project of the anchor.

The figures show a preparing, ploughing, reversible anchor mainly comprising a composable supporting frame T, an oleo dynamic, reversible tool-carrier to be connected to the tractor and a plurality of elements, each consisting of an anchor 1 with two incorporated ploughing bodies 4D and 4S.

Said plouging bodies are provided on the same side of each anchor 1 so that following to the 1802 revolution perform- ed on frame T, by means of the oleodynamic tool-carrier P, they may work in succession on the right and on the left o the preparing anchor 1 during the front and back -movements of the tractor.

Each anchor 1 is provided with two wearing supports 2 and with two reversible plough-shares 3, all of the kind that may be replaced following to wearing or damage.

In consideration of the anchors' dimensions shown in figur 6, and taking into account the number of the mounted an¬ chors 1 as well as the dimension of the anchor-carrying frame T, the object according to the present invention may

TE E be coupled only to tractors with 150/180 HP. Consequently, by reducing or increasing the number of the anchors, it is possible to reduce or increase the tractor's power.

The dimensions, expressed in millimeters in figure 6, are related to elements having an average preparing capacity of 60 to 70 centimeters and an average ploughing capacity of 30 to 40 centimeters.

The novelty of the ploughing method realized according to the object of the present invention consists in the contem¬ porary mechanization of the preparing and ploughing opera¬ tions of the ground and in the methods of performing the same.

Even if preparing means are already known in various shapes and dimensions, the realization of reversible, preparing anchors coupled to the ploughing body, is a novelty in the primary application in the farming field.

By means of above mentioned method, it is possible to rea¬ lize, in reduction or increasing proportionality relating to the data shown in the enclosed drawings, preparing an¬ chors, ploughing bodies and anchor-carrying frames having greater or smaller dimensions, so as to adequate the in¬ strument to the different powers of the tractors.

SUBSTITUTESHEET The variety of the preparing and ploughing instruments may be considerably increased by increasing or reducing the number of the working elements and within variable dimen¬ sions, as it already occurs for the conventional ploughs.

In the variant according to figure 5, a preparing, plough¬ ing, semi-anchor is shown obtained by the coupling of a ploughing body with a semi-anchor; and coupling one or mo¬ re of said semi-anchors to non-reversible carrying frames, non-reversible preparing, ploughing elements are obtained that may be different in dimensions and in the number of their elements.

Obviously, the reciprocal positions of anchors 2 and of ploughing bodies 4, according to the requests of the users, may .vary, e.g., as shown in figure 4, wherein the connec¬ tion takes place by means -of variable distancers 5, block¬ ed by coupling nuts 6 with variable length, and other pos¬ sible adjustments.
