Corresponding parts and sizes are shown in the figures 1 to 7 provided with the same reference numerals.

1 and 2 show a first embodiment of a harrow 1 comprising a rotary cultivator 2 as a soil treatment unit and a dosing device 3 for water-storing material, in particular in solid form as granules, for example a "Geohumus" or "Gaspo Aquaprotect" granules, or in liquid or viscous form, for seeds or for fertilizers or for a mixture of at least two of these components. Usually, such a tillage device 1 from a towing vehicle, not shown, e.g. As a tractor or tractor, pulled and used for processing agricultural land such as fields or fields, but can also be used in landscaping or horticulture, for example, for the preparation or creation of lawns.

The rotary cultivator 2 has several juxtaposed pairs of tines 4 on, each via an associated rotary shaft 5 with a gear 6 around a vertical, longitudinally through the rotary shaft 5 extending axis of rotation A co-rotating connected and are driven. Each pair of tines 4 indicates two curved or curved tines in the direction of rotation ("on handle") or in the direction opposite to the direction of rotation ("sluggish") 41 on, at one with the rotary shaft 5 firmly connected turntable 40 are fixed and form a "gyroscope" with this and are arranged offset diametrically to the axis of rotation A, preferably in mutually equal distance from the axis of rotation A. The transmission 6 is connected via a, known per se and not shown in detail, with the, also not shown, towing vehicle.

During a movement of the soil tillage implement 1 in the machine direction (pulling direction, forward direction) B (in 1 to the left) are simultaneously on the gearbox 6 the rotation shaft 5 and thus the turntable 40 with the pair of prongs 4 the tines 41 set in rotation about the axis of rotation A.

In an operating state, the two prongs engage 41 of the tine pair 4 in the ground 20 one. By the rotation or rotation of the tines of the tine pair 4 around the axis of rotation A, with or even without the simultaneous movement of the harrow 1 with the tine pairs 4 in the machining direction B, the solidified soil 20 in a editing area 45 around the rotating tines 41 the tine pairs 4 torn or milled, with larger lumps are crushed and the soil material partially dug and changed in its depth distribution, so deeper material is partially brought up and upper material is partially transported down or brought, so that an upper layer with loosened soil 21 forms. stubble 19 , So remnants of harvested plants such. As straw, are thereby introduced into the soil and in the layer of loosened soil 21 mixed. This layer with loosened ground 21 gets behind the prong pairs 4 from a leveling rail 7 smoothed and then by a roller 8th solidified again. The down-measured depth of the machining area 45 is from the vertical extent of the tines 41 dependent and forms the processing depth t of the tine pairs 4 and thus the whole tillage implement 1 ,

The tine pairs 4 are preferably laterally arranged so close to each other that their processing areas 45 largely abut each other or overlap each other, so that the tillage over the entire working width of the rotary cultivator 2 he follows. The number of tine pairs 4 depends on the working width and is in particular between 3 and 70, preferably between 8 and 12.

At the end of the tillage implement 1 is still a ground wheel (or a bottom roller) 9 intended.

Above the rotary cultivator 2 is, essentially in the middle, a dosing device 3 arranged, which a funnel or container-shaped storage device 10 for receiving and storing introduced granular or present in the form of solid material, which is preferably water-storing granules G or comprises. In the following, only granulate G is used, but the material to be introduced into the soil may also be seed or fertilizer or any desired mixture of these materials with water-storing material, in particular granulate G.

The metering device can be, for example, a roller metering device or a cam wheel metering device or also a pneumatic metering device based on the Venturi principle. At its lower end is the storage device 10 with a metering nozzle 11 connected at its lower end by a metering roller 12 is completed. The metering roller 12 is arranged and designed so that by means of a rotary movement of the metering roller 12 the material to be introduced, in particular granules G, in defined portion sizes in a feed tube 15 is passed on. Depending on the metering roller or metering device used, defined portion sizes can be passed on in defined time intervals or a continuous volume or mass flow.

Adjacent to the dosing device 3 is a fan 13 arranged, which a flow of air through an air supply hose 14 the dosing device 3 supplies. The air flow is directed so that it the metering 11 flows through the metering roller 12 around or through it and into the feed tube 15 into flows. The fan 13 is designed so that it has a continuous air flow under low overpressure, z. B. 0.1 bar to 0.3 bar generated. By the air flow of the transport material to be introduced G in the metering 11 and in the delivery hose 15 supported. In particular, the strength of the air flow can be adjusted to different materials to be introduced, for example with different grain sizes.

Due to the friction of the material G to be introduced within the feed tube 15 can the delivery hose 15 possibly electrostatically charged, whereby the transport of material is made difficult by the resulting electrostatic attraction. Therefore adhering material particles are detected by the air flow and expelled, so that the free transport of material is ensured. The diameter or cross section of the feed tube 15 is dependent on parameters of the material to be introduced G, such. B. grain size or coefficient of friction selected.

The delivery hose 15 for the granulate G to be introduced is via a mounting flange 16 on a carrier plate 17 attached and opens into an opening in the carrier plate or is through an opening in the carrier plate 17 performed and opens below the support plate 17 , The material to be introduced, in particular granules G, indicated by the small particles, occurs in this mouth or outlet region of the feed tube 15 on the carrier plate 17 off and now falls in different directions, indicated by the three arrows, due to gravity and with different initial impulses down.

The mouth or exit area is in accordance with 1 above the turntable 40 and therefore also the tines 41 of the gyroscope with the pair of tines 4 , As a result, the exit of the granules G to be introduced only insignificantly from that through the tine pairs 4 in their editing area 45 impacted soil material and granules G can move freely and unhindered to the ground 20 fall.

The carrier plate 17 serves at the same time as a baffle plate upwards for the raised or whirled up soil and dust and for the material G to be introduced upwards.

In order to prevent the falling granules G being blown away or unevenly distributed by winds, is according to 1 and 2 at the front of the carrier plate 17 and preferably also on the side of a down hanging flexible protective curtain (or: sealing wall, windshield, vertical housing wall) 27 provided, for example, may consist of a rubber or elastomer or a solid textile material and opposite to the ground 20 lying stones or other obstacles should be flexible, but can not be significantly pushed away by wind. The protective curtain 27 and the carrier plate 17 form a protective housing or a sealing or dosing to protect the exiting and falling particulate, powdery or granular material G from air movements and winds.

Preferred is as in 2 shown, in front of each pair of prongs 4 upstream of a flange 16 with connected supply hose 15 provided so that each pair of tines 4 and its editing area 45 separately and targeted granules G is supplied. The feed hoses 15 are via a distributor not shown in detail with the supply or storage device 10 connected to the granules G. It can also be a branch of one feed hose 15 for the distribution of granules G on several outlets or feed areas 50 ,

When moving the soil tillage implement 1 in the processing direction B, the dropped granules G finally gets into the processing area 45 of the tine pair 4 and is mixed into the soil during its processing. That through the delivery hose 15 transported material G is seen in the machine direction B so before the tine pair 4 and its editing area 45 applied. As a result, the material G of the rotating prong pair 4 and that of this moving soil detected and over the entire processing depth t in the soil layer with loosened soil 21 mixed and thereby distributed deep in the ground and in the lower area.

By applying the material G locally and temporally before the pair of prongs 4 a high degree of mixing is achieved and the material can be introduced into a defined soil layer at a defined depth t.

The depth t, in which the material is introduced, is dependent on the length of the tines 41 of the tine pair 4 , which is chosen in particular between 10 cm and 60 cm, preferably between 15 cm and 40 cm.

Usually the tines are 41 interchangeable and can be adapted in length and shape to the respective conditions.

By tillage according to the invention with a harrow 1 In particular, the introduction of dry or pre-hydrated water-storing granules G is possible especially in sandy and / or dusty soils and also in the greater depths t required for successful planting. This allows not only the irrigation and water storage for growing plants that grow their roots in the granules G, also a binding of dust and sand with the granules G in a particular soil layer, whereby the removal of the soil or soil erosion is reduced.

It may also be provided that the metering device and / or the feed device has a device for pre-moistening granules G to be introduced, which preferably contains the granules G during the fall after they leave the feed tube 15 moistened, for example by means of spray or misting nozzles, which are connected via water hoses with a water supply and a water conveyor or pump. By pre-moistening the binding power of the granules is increased and the dust effect is reduced. In addition, a subsequent moistening may be provided.

For example, a water tank 28 on a device frame of the soil cultivation device 1 be fixed, containing liquid, which can be used to pre-moisten the granules G to be introduced. A storage container 29 for storing granules may suitably on or at the water tank 28 be attached. In addition, a section of a surface of the water tank 28 as a tread 30 be educated. By such a design of the water tank 28 is an ergonomic filling of the dosing device 3 by an operator. Also, with a suitable arrangement of the water tank 28 on the device frame good accessibility of possibly maintenance-requiring components, such as dosing 3 , Metering roller 12 or blower 13 , given. The water tank 28 is via a fluid supply hose 31 with the granule feed hose 15 connected so that the moistening of the granules directly adjacent to the tine pairs 4 he follows.

The liquid supply hose 31 is in the embodiment shown here to the mounting flange 16 Tailed, the baffle plate 17 is attached. The supply of liquid, in particular with respect to quantity and / or flow rate, can be tuned by a control device to the supply of granules. Depending on the type and grain size of the granules and the amount of granules fed per unit time, the supply of liquid must be adjusted.

Because the tillage machine 1 connected to the towing vehicle, the transmission 6 is connected to a drive shaft of the towing vehicle, the speed of the tine pair 4 usually depending on the speed of the towing vehicle. A ground wheel 9 , which with the soil tillage implement 1 is connected and which with the soil cultivator 1 pulled along in a direction B, stands with the dosing device 3 and in particular with the metering roller 12 in operative connection, such that the dosage takes place as a function of the driving speed. This means that the parameters application rate and tine pair speed depend on the driving speed. This ensures that even with varying or uneven driving speed, the desired amount of material to be applied material is introduced into the soil. These parameters themselves are variably adjustable and can be adapted to the particular material to be applied or the quality of the soil to be processed.

3 shows a second embodiment of a harrow 1 with central supply of material, in particular granules G, at the tine pairs 4 , The end of the delivery hose 15 is via a hinged mounting flange 18 at an upper end of the rotary shaft 5 of the tine pair 4 attached. The mounting flange 18 and the delivery tube 15 are from the rotational motion of the rotary shaft 5 decoupled.

The rotation shaft 5 allows through their training as a hollow profile tube, the passage of the material or granules G and flows through an outlet opening 42 in the middle of the turntable 40 then into the space between the tines 41 , This is done by the feed tube 15 supplied material G through the hollow profile tube of the rotary shaft 5 passed down through it and falls through the outlet opening 42 between the tines 41 of the tine pair 5 directly on and in the editing area 45 falls and gets immediately from the tines 41 mixed into the soil.

The feed area 50 for the granules G is therefore according to 3 directly above the editing area 45 and not, as in 1 , in front of the editing area 45 , The embodiments according to 1 and 2 such as 3 can also be combined, so that both a feed area 50 before as well as above the processing areas 45 is provided.

Instead of a rotary cultivator 2 with prongs 41 On grip can be used in all embodiments, depending on the type of soil, another device as a soil treatment unit, in particular a harrow with trailing tines or a harrow with fixed, non-rotating tools such. As a harrow or a cultivator with fixed prongs or a plow, for example, with a wing group.

4 shows an embodiment of a connection of Granulatzuführschlauchs 15 to the mounting flange 16 , The mounting flange 16 is in a seat on the baffle 17 fixed, for example by a screw or a welded joint. Below the mounting flange 16 has the baffle plate 17 an opening through which out of the Granulatzuführschlauch 15 passing granules can escape and fall to the ground.

At the bottom, so from the mounting flange 16 opposite side of the baffle plate 17 , is an annular sprayer 32 arranged the opening of the baffle plate 17 essentially completely relocates. The annular sprayer 32 is designed as a hollow profile tube and communicates with the Flüssigkeitszuführschlauch 31 in fluidic connection. spray openings 33 are arranged distributed at regular intervals in the circumferential direction and in the radial direction inwardly, as directed to the center of the ring, directed.

Will liquid through the liquid supply hose 31 fed, it flows into the hollow profile tube of the annular spray device 32 and enters through the spray holes 33 therethrough. From the granule feed hose 15 escaping granules fall or move substantially centrally through the annular spray means 32 through and is thus moistened from all sides by liquid. This results in a very homogeneous or uniform moistening of the granules. The granules are in such an arrangement outside the Granulatzuführschlauchs 15 moistened. This avoids that the granules already within the Granulatzuführschlauches 15 swells up and this clogged. At the same time, the granules immediately after leaving the Granulatzuführschlauches 15 moistening, which gives the granules a higher weight, so that it is less blown by the wind on the way to the ground.

The described arrangement is relative to the pair of prongs 4 above and in processing direction B in front of the tine pair 4 arranged.

5 shows an alternative embodiment to that just described. The granule feed tube 15 is with a connecting piece 34 integrally formed, for example in the form of a T-shaped fitting. A spray nozzle 35 is on or inside the connection piece 34 held so that from the spray nozzle 35 leaking liquid, preferably uniformly and / or homogeneously distributed in an end portion of the Granulatzuführschlauchs 15 sprayed or sprayed or passed. The end section of the granule feed tube 15 can dull as shown on the baffle plate 17 be welded. Likewise, of course, training with a mounting flange is conceivable.

The granulate gets inside the granule feed tube 15 and immediately before exiting the Granulatzuführschlauch 15 moistened. In this embodiment, the granules become liquid by the pressure in the end portion of the Granulatzuführschlauchs 15 pushed out of this, so that no granules remain in the said end section and the Granulatzuführschlauch 15 can clog. Again, a very good and homogeneous moisture penetration of the granules is guaranteed.

Also in this embodiment, the arrangement above the tine pair 4 and in the processing direction B before the tine pair 4 arranged.

6 shows a pair of prongs 4 as for example in a modification of the harrow after 3 can be used and which a turntable 40 as well as tines 41 includes. The prong pair 4 is with the turntable 40 about a camp 54 rotatably mounted on a fixed axis of rotation, wherein the axis of rotation similar to the rotation shaft 5 is designed as a hollow profile tube. Accordingly, by the Granulatzuführschlauch 15 passed granules through the hollow profile tube of the axis of rotation down into an end portion of the axis of rotation. This end portion of the rotation axis is as a baffle 51 formed, which different sized outlet openings 53 having.

The outlet openings are arranged vertically one above the other in the wall of the hollow profile tube of the axis of rotation and are larger from top to bottom. The outlet openings 53 are arranged transversely to the processing direction B, so that the exit movement of the granules G transversely to the processing direction B of the harrow 1 he follows. Furthermore, baffles 52 for example, semicircular around the outlet openings 53 arranged around, so that the outlet openings are at least partially covered in the machine direction B. By accurately positioning and selecting the size of the outlet openings 53 For example, the placement depth or an area of the placement depth of the granulate G can be precisely adjusted. Also, the distribution of the granules G over a certain range of deposition depth can be precisely adjusted by the size of the holes. Such a baffle 51 Of course, it can also be used in conjunction with a rotary shaft 5 powered tines 41 be used.

7 shows a sectional view of a baffle 51 its wall outlet openings 53 has, which are arranged vertically one above the other. The different sizes of the outlet openings 53 , in particular the different diameters are recognizable. Inside the hollow profile tube of the axis of rotation are feed plates 55 arranged, in each case a feed plate 55 an outlet opening 53 assigned.

The feed sheets 55 are slightly curved or substantially dish-shaped, so that passed through the hollow profile tube granules from the feed plates 55 formed sliding surface is directed or guided in the direction of the outlet openings. The length or size of the individual feed sheets 55 is selected according to the amount of granules that the respective outlet opening 53 should be supplied. In particular, the feed plates protrude 55 depending on its vertical position and the size of the associated outlet opening 53 different far into the interior of the hollow profile tube into it, wherein the passage space for the granules G in the interior of the hollow profile tube in the vertical direction from top to bottom is gradually reduced gradually and the respective outlet openings 53 in each case a precisely defined amount or a precisely defined stream of granules G is supplied.

The lower end of the hollow profile tube is from the bottom feed plate 55 closed, so that all the granules laterally from the baffle 51 is discharged into the soil.
