Soil cultivation implement having a device for reconsolidation
A towed soil cultivation implement ( 1 ) is proposed in which the soil tillage tools ( 5 ) are guided by a contact pressure controlled depth guide device ( 9 ), which enables a constant weight load on a downstream, adjustable reconsolidation implement ( 6 ) on uneven ground as well. In the process, the pull line between tractor ( 3 ) and soil cultivation implement ( 1 ) are maintained in an optimum position.
1. Towed soil cultivation implement ( 1 ) comprising a draw gear ( 2 ) for suspending on a tractor ( 3 ) and a frame ( 4 ) connected to the draw gear ( 2 ), the frame including a front section proximal the tractor, a middle section and a rear section distal from the tractor having transport wheels, soil tillage tools ( 5 ) connected in a front section of the frame ( 4 ) for tilling and loosening a ground ( 7 ), levelling tools ( 23 ) coupled to the front section of the frame downstream from the soil tillage tools, a reconsolidation device ( 6 ) comprising at least one roller for reconsolidation and re-compaction of the loosened ground ( 7 ) disposed on the rear section of the frame downstream from the soil tillage tools ( 5 ), the levelling tools ( 23 ) and the transport wheels, wherein the reconsolidation device ( 6 ) is adjustable in a height setting with respect to the soil tillage tools ( 5 ) through an external power with at least one adjusting device ( 8 ), at least one depth guide device ( 9 ) arranged adjacent to the front section by the soil tillage tools ( 5 ), wherein the at least one adjusting device ( 8 ) for adjusting the height setting of the reconsolidation device ( 6 ) is coupled to a controller ( 10 ) for controlling a contact pressure of the at least one depth guide device ( 9 ) on the loosened ground ( 7 ) wherein responsive to an increase or a decrease in the contact pressure of the depth guide device ( 9 ), the height setting of the reconsolidation device ( 6 ) is readjusted by the controller ( 10 ) through the at least one adjusting device ( 8 ).
2. Towed soil cultivation implement in accordance with claim 1 , wherein a minimum distance between the depth guide device ( 9 ) and one of the soil tillage tools ( 5 ) is less than a minimum distance between the front section of the soil tillage tools ( 5 ) and the reconsolidation device ( 6 ).
3. Towed soil cultivation implement in accordance with claim 1 , wherein the contact pressure of the depth guide device ( 9 ) on the ground ( 7 ) can be selected and adjusted as a control variable in steps or continuously.
4. Towed soil cultivation implement in accordance with claim 1 , wherein the contact pressure of the depth guide device ( 9 ) on the ground ( 7 ) is measured with measuring instruments ( 11 ) on the depth guide device ( 9 ).
5. Towed soil cultivation implement in accordance with claim 1 , wherein actuating forces of the at least one adjusting device ( 8 ) for adjusting the height of the reconsolidation device ( 6 ) are recorded by the controller ( 10 ) and used to regulate the contact pressure of the depth guide device ( 9 ).
6. Towed soil cultivation implement in accordance with claim 1 , wherein additional adjusting devices ( 12 ) for setting the frame ( 4 ) in a working position are provided whose actuating forces are indicative of the contact pressure of the depth guide device ( 9 ) and are included to regulate the contact pressure through the controller ( 10 ).
7. Towed soil cultivation implement in accordance with claim 1 , wherein the controller ( 10 ) is a three-point controller.
8. Towed soil cultivation implement in accordance with claim 1 , wherein the controller ( 10 ) is designed to operate on the control or positioning elements of the tractor ( 3 ).
9. Towed soil cultivation implement in accordance with claim 1 , wherein the depth guide devices ( 9 ) are arranged laterally to the front section by the soil tillage tools ( 5 ).
10. Towed soil cultivation implement in accordance with claim 1 , wherein the front section comprising the soil tillage tools ( 5 ) forms a trapezoidal distribution of the soil tillage tools ( 5 ) at least in front rows.
11. Towed soil cultivation implement in accordance with claim 1 , wherein at least one additional adjusting device ( 13 ) is attached to the draw gear ( 2 ) that is designed to transfer part of a weight of the soil cultivation implement ( 1 ) to the tractor ( 3 ).
12. Towed soil cultivation implement in accordance with claim 1 , wherein the soil cultivation implement ( 1 ) is attached to a height-adjustable transport chassis ( 14 ).
13. Towed soil cultivation implement in accordance with claim 1 , wherein the transport chassis ( 14 ) is designed to be height-adjustable via adjusting devices ( 40 ) for adjusting the height of the reconsolidation device ( 6 ) together in a sequence control with the at least one adjusting device ( 8 ).
14. Towed soil cultivation implement in accordance with claim 1 , wherein the soil tillage tools are selected from tined cultivators, short disc harrows, and combinations thereof.
