A soil cultivation device, which is movable relative to the soil in a direction of movement, for the deep loosening of soils, comprises perforating tools guided on supporting arms that move up and down, and a damping device having an elastomeric body, for damping a returning movement of the perforating tools pivoting relative to the supporting arm during withdrawal from the soil. For smoother and faster operation, a first side of the elastomeric body is firmly connected to a retaining member, resting flat on a retaining surface of the retaining member, and a second side of the elastomeric body opposite the first side is firmly connected to an input member in a firmly attached manner, resting flat on a retaining surface of the input member, and the body of elastomeric material is elastically biased by a separate biasing device acting against the body. |

1. A soil cultivation device, which is movable relative to the soil in a direction of movement, for the deep loosening of soils, the soil cultivation device comprising:
a device chassis or device frame; at least one supporting arm hinged with a first portion to the device chassis or the device frame so as to be pivotable up and down about a first pivoting axis that is stationary relative to the device chassis or device frame; a driving mechanism configured to drive the up-and-down movement of the at least one supporting arm; and at least one perforating tool hinging device, respectively, per supporting arm, by which at least one perforating tool is hinged, so as to be pivotable relative to the associated supporting arm about a second pivoting axis, to a second portion of the supporting arm in such a way that the perforating tool is driven into the soil when moving the supporting arm downwards and that the perforating tool hinging device is pivoted relative to the supporting arm and the soil at least when the perforating tool has been driven in and during further movement of the soil cultivation device in the direction of movement, so that the soil can be loosened underneath the soil surface, and at least one gearing mechanism interposed between the perforating tool hinging device and a damping device in to at least partially dampen the relative movement between the perforating tool hinging device and the associated supporting arm; the damping device having an elastomeric body of an elastomeric material fitted between a retaining member configured to attach the damping device and an input member connected to the gearing mechanism, so that, when a movement is initiated by the gearing mechanism, the retaining member and the input member are able to move while the elastomeric body is being deformed for damping; and at least one of the following:
a first side of the elastomeric body is connected to the retaining member in a firmly attached manner, resting flat on a retaining surface of the retaining member, and that a second side of the elastomeric body opposite the first side is connected to the input member in a firmly attached manner, resting flat on a retaining surface of the input member; andthe body of elastomeric material is elastically biased by a separate biasing device acting against the body. |
