Plough device comprising two cutting elements

Plow device according to claim 1, characterized in that, at the same time as cutting the earth ridge, the first cutting element is kept at the desired cutting depth thereof by means of a compression force pressing, by means of the earth ridge, on a guide plate representing a plowshare.

Plow device according to claim 1, wherein the first cutting element and the second cutting element are arranged relative to one another such that the cutting region of the first cutting edge of the first cutting element is spaced apart vertically from the second cutting edge of the second cutting element.

Plow device according to claim 1, wherein the first cutting region is formed within a first cutting plane and the second cutting region is formed within a second cutting plane, wherein the first cutting plane and the second cutting plane form an angle relative to one another of from 30° to 135°, in particular 45° to 110°.

Plow device according to claim 1, wherein the first cutting edge of the first cutting element and/or the second cutting edge of the second cutting element is/are provided with respective recesses and is/are thus toothed or serrated.

Plow device according to claim 1, wherein the second cutting edge is a cutting edge around the circumference of the second cutting element.

Plow device according to claim 1, wherein the first cutting element is in the shape of a cone or in the shape of a truncated cone, and/or the second cutting element is in the shape of a cone or in the shape of a truncated cone.

Plow device according to claim 1, wherein the moldboard comprises a receiving region for receiving the first cutting element, wherein the first cutting element is received in the moldboard such that the first cutting region of the first cutting edge protrudes from the moldboard in the plowing direction.

Plow device according to claim 1, wherein the support structure is designed such that the first cutting element and/or the second cutting element can be adjusted, relative to the moldboard, in the plowing direction.

Plow device according to claim 1, wherein the support structure is designed such that the spacing between the first cutting region of the first cutting edge of the first cutting element, and the second cutting region of the second cutting edge of the second cutting element, can be adjusted.

Plow device according to claim 1, in which the first cutting element is formed in the manner of a hollow plate, having a curvature of the inner surface thereof, such that, during plowing, the earth ridge that is separated laterally from the ground by means of the first cutting element is twisted by the curvature of the inner surface and, after emerging from the hollow plate, can be replaced on the ground in the furrow as a turned earth ridge.

Plow device according to claim 1, in which the second cutting element comprises an angle adjustment means, with respect to the work angle α thereof, using which means it is possible to set a work angle α that is positive in the plowing direction.

Plow device according to claim 12, in which the work angle α can be adjusted mechanically or hydraulically or electrically using the angle adjustment means.

Plow device according to claim 12, in which a spring ensures a required pull-down force when moving the second cutting element along the furrow base, and is of such a spring force that the second cutting element is oriented so as to be substantially horizontal, owing to the weight of the earth ridge.

Plow device according to claim 1, in which the second cutting element comprises an internal bearing, arranged in a tube, in the manner of a drum bearing.

Plow device according to claim 1, in which the second cutting element is designed as a spoked wheel and/or comprises a tapering cutting edge having an undercut in the spoke region.

Plow device according to claim 1, in which the second cutting element consists of a composite material, in particular the lower face thereof that faces the furrow base, and the cutting edge thereof, consist of steel, and the upper face thereof that faces the earth ridge consists of a wear-resistant and adhesion-reducing plastics material.

Plow device according to claim 1, in which the second cutting element is formed in two parts and comprises a rotating cutting ring which is supported with respect to a stationary inner wheel by means of a bearing.

Plow device according to claim 18, in which the cutting ring is designed so as to be actively driven.

Plow device according to claim 1, in which the second cutting element is a cutting blade.

Plow device according to claim 1, in which the second cutting element is actively driven and has as cutting width which cuts the base region of the earth ridge for at least two following first cutting elements.

Method according to claim 22, in which a work angle α of the second cutting element, defined in the plowing direction, is adjusted mechanically or hydraulically or electrically.
