    GRUBBER ELEMENT FOR A PRESERVATIVE FLOOR PROCESSING DEVICE
    AND
    AGRICULTURAL DEVICE THEREFOR
    The invention relates to a cultivator for a device for conservation tillage, consisting essentially of a cultivator tine, a Schmalver and a Scharverbreiterung, which has on both sides of the Schmalschar each rotatably mounted in an adapter disc.
    It is known from practice to equip cultivator elements for better preparation of the soil with wing shares. These are near the lower end of the Zinkens laterally projecting rigid wings. Their frictional resistance is significant, which increases the traction requirement and thus the fuel consumption of the towing vehicle. At the "leading edges" of the wings root remains hang, which further increases the traction requirement and hinders the mixing of the soil with humus and plant residues.
    From the patent RU 2028740 CI a generic cultivator element is known, which has as a blade widening two significantly spaced transversely spaced conical discs with radially projecting teeth. The discs are, as far as recognizable, rotatable and can be set in the movement of the device through the soil in rotation when they are only (or predominantly) on the side facing away from the tine of its contour with the ground in touch. But that is not recognizable. One of the driving speed of the device corresponding peripheral speed of the discs is so difficult to reach bar, especially as this can even be in the opposite direction by root remains. Also in this device, the same negative consequences occur as in the known from practice device.
    It is therefore an object of the invention to improve a generic device so that the negative consequences mentioned do not occur. The slices should be rotated freely and with the least possible slip from the soil in rotation, not clog or even be self-cleaning, and achieve a good mixing of soil and plant remains. In this case, the required traction should be minimal, which benefits the device carrying farm tractors, the fuel consumption and reduced pollutant emissions and the environment benefits.
    According to the invention that is achieved with the features of the first claim.
    The plate of the adapter is just so wide that it encloses the receptacles for the axes of rotation and covers the part of the discs, which moves in the opposite direction of travel of the device. The arrow-like front edges of the adapter deflect the field soil with low traction requirement from the side. Because the distance between the axes of rotation is smaller than the diameter of the disks, the areas of the disks lying within the axes of rotation overlap, so that there is no bottom friction acting counter to the direction of rotation of the disks. Thus, the discs with minimal slippage and maximum torque are offset in opposite directions.
    In order to partially cover each other, the discs are offset in the axial direction by their thickness against each other. As a result, they act together on the downstream side. They clean each other and cut up leftover root remains. They are thus self-cleaning, which prevents an increase in the traction requirement in contamination or clogging of the discs.
    In an advantageous development, the inclined to the horizontal slices are higher than the top of the Schmalschar arranged. Due to the deeper furrow drawn by the narrow share, the soil friction forces which act counter to the direction of rotation of the disks are further reduced and the mixing of earth, humus and plant residues promoted by the inclined disks is further improved.
    In an advantageous embodiment, the adapter is bolted to the tine, the tine or adapter having a number of transverse bores for selectively positioning the adapter in various positions, including tilt and working depths. So the cultivator elements of the respective soil conditions or other requirements are customizable. With appropriate design of the adapter, a rigid widening of the prior art can be replaced by the invention. This can therefore be retrofitted.
    The discs may be formed in various shapes with different contours and diameters. As plane-parallel circular disks, they are simple and inexpensive to produce. Preferably, they have a sharp-edged contour. This lowers soil resistance and cuts up entrained root parts.
    In a further development, the contour of the discs has indentations. As a result, the drive is further improved by the soil friction, the self-cleaning effect, and the mixing.
    According to another aspect, the Schmalschar is attached to the front side of the prong and upwards includes a baffle to them.
    The invention also relates to a whole agricultural device for conservation tillage, which is equipped with the cultivator tines according to the invention.
    In the following the invention will be described and explained with reference to an embodiment of the cultivator element according to the invention. They show:
    FIG. 1: a cultivator element according to the invention in an axonometric representation, seen obliquely from the front, FIG. 2: detail A in FIG. 1 enlarged, seen from the side and in working position, FIG.
    3 shows a view from the front according to arrow III in Fig. 2,
    4 shows a section according to IV-IV in FIG. 3, enlarged.
    In Fig. 1, the frame of an agricultural tillage machine by a cross member 1 and a longitudinal member 2 is indicated. The frame is connected to a tractor in the usual way and can accommodate other tillage tools (eg disc ploughshare). On the cross member 1, a number of cultivator elements 3 is fixed at certain intervals. The attachment can be configured as desired, by welding, but preferably by means of a displaceable and lockable on the cross member 1 connecting piece. 9
    The cultivator element 3 consists of a C-shaped cultivated tine 4 with the top of the connector 9, from a mounted on the front side of the cultivator tine 5 and a summarily denoted by 6 Scharverbreiterung, which is connected by means of an adapter 7 with the cultivator tine 4. At the Schmalschar 5 can still connect a baffle 8 upwards.
    Fig. 2 shows the cultivator element 3 according to the invention in use, wherein the driving and machining direction is indicated by the arrow 10. The flow of the field soil takes place in the direction opposite to the arrow 10. The Schmalschar 5 dives into the soil soil 11, its tip 12 determines the processing depth. The blade widening 6 acts by means of two substantially circular discs 13,14 outside of the narrow share 5 on the soil. The discs 13,14 are rotatably mounted in the adapter 7 and are inclined with respect to the horizontal by an acute angle of attack 17. Their lowest point is at a distance 16 above the tip 12 of the Schmalschar 5. Distance 16 and angle 17 can be adjusted according to the circumstances. For this purpose, for example, in the adapter 7 and in the prong 4 a number of holes 18,19 provided for bolts, not shown, which allow the connection in different positions.
    The discs leave a loosened and mixed soil soil 20, which is indicated by the curve 21.
    FIGS. 3 and 4 show the blade widening 6 in detail. The adapter consists of with the prong 4 screwed fastening tabs 26 and a normal plate to 25. They could also be slightly inclined on both sides. The plate is substantially flat, but with an offset 31 corresponding to the axial displacement of the discs 13,14, and forms on its An-strömseite swept and beveled edges cutting edge 30 and on the downstream side ee similar e trailing edges. Within the end edges 30 and trailing edges 29 a receptacle for axes of rotation 27 of the discs 13,14 is provided on both sides. The axes of rotation 27 have a horizontal distance 28 from each other, which is smaller than the diameter of the discs 13,14. The direction of rotation of the discs 13,14 is indicated by the arrows 32, and the direction of travel - opposite to the direction of flow of the field soil - by the arrow 10th
    The discs 13,14 are substantially circular and offset in the direction of their axes so far apart that they can overlap each other, corresponding to the smaller distance 28 of their axes 27. The contour and surface of the discs 13,14 can be designed very different. In the embodiment shown here, they have razor-sharp edges 33 and recesses 34 distributed over the circumference. Thus, they form a cutting zone 35 when they meet on the outflow side.
    The mode of operation is as follows: The field soil 11 "flows" counter to the direction of travel 10 toward the narrow share 5 and is divided by the latter into two sub-flows .The sub-flows are deflected further by the swept end edges 30 and flow over the outer part of the upper side of the discs 13, 14. Friction causes the discs to rotate.
    It is essential that only the parts of the discs 13,14 outside of their axes of rotation 27 come into contact with the partial streams. Only there does the flow direction coincide with the direction of rotation 32. Touch within the axes of rotation 27 would counteract the direction of rotation 32. This is mainly prevented by the narrow share 5 and the swept edges 30, but also by the height distance 16 and the inclination angle 17. Thus, the discs 13,14 are rotated with a minimum of slip and traction requirement in rotation.
    The bookings 34 of the two discs 13,14 improve the mixing of the soil and form when they meet in the outflow a cutting zone 35, are crushed in the entrained plant parts. From the cutting zone 35, the two disks 13, 14 cooperate in their overlapping area and clean each other. The trailing edges 29 of the plate 25 contribute to self-cleaning. The overlapping area is not visible in the figures, because covered by the plate 25. The self-cleaning of the discs 13,14 prevents an increase in traction requirement by constipation and jammed plant parts.
    From the described embodiment can be deviated from within the scope of the claims. Overall, the task is solved so completely.
