The laterally free displaceability of the holding hafts (3 or 3a) for the loosening coulters (2b) which becomes possible thereby allows, above all, the easy loosening of the wheel tracks of the tractor (not shown). <IMAGE>

Description

Device combination for deep loosening, seedbed preparation and ordering, -with verhm. light tractors.

The present invention relates to a device combination for tractors for deep loosening, seedbed preparation and ordering with verhm.

light tractors.

Under the file number P 34 24 250.3 a new procedure was under Protection provided, with deep loosening, seedbed preparation and cultivation of the soil optionally carried out either in one operation or in two operations can be. In the former case, this is done by arranged in two rows Shares, of which the shares in the first row are attached to one front Frame and the shares of the second row on a rear frame and to the shares the first row on a gap and staggered in the direction of travel, the loosen the soil, and using rotating tools that create an adjustable soil layer Crumble ready for sowing so that it may be recompacted by an attached packer roller and can be sown using a mounted or trailed seed drill.

In the second case, this is done by the fact that the ground in a first Operation with the on the cultivator in verhm. at large distances Flocks of leaves in strips and preferably only between or next to the lanes is loosened, and that in a second step that in the first step Unloosened field strips finished by blade shares attached to the rotary harrow loosened and the whole "field bed" from the rotating tools of the rotary harrow is crumbled ready for sowing.

Such combinations of devices consist of at least one to the Work equipment that can be coupled to the tractor power lift, e.g. a cultivator whose Frame arranged transversely to the direction of travel, holding handles for loosening coulters are to which at least one further working device, e.g.

a rotary harrow can be coupled to which is transverse to the direction of travel extending frame at least one gear and at least one in side end shields Bearing motor-driven tool carrier with rotating prongs or milling knives is arranged to crumble the top soil layer and preferably also to that a crumbling or packer roller and / or a built-up or trailer seed drill can be coupled is.

With this combination of devices, handles are used for the tools Loosening both at considerable lateral distances on the frame of the first implement, and arranged on the frame of the second implement. The one on the frame of the second Working device arranged handrails are on gap to the-front handrails arranged on an additional frame tube running above the frame and the transmission, its outer ends with the also on the main frame of the second device with each other connected end shields are screwed or welded, and at a distance above and - viewed in plan view - between the front and rear edges of the main frame and also located above the transmission is. In addition to the handle holders for the handlebars, there are also at least one on this frame tube two consoles for the attachment devices of the lower links of the tractor and a forward protruding console for the top link attached.

The exemplary embodiments according to FIGS. 3a, 3b, 4a, 4b, 4c of the parent application are characterized by being rigidly connected to the frame of the seedbed preparation device additional support tube or frame tubes to the optional handle holder for front or holding handles arranged behind the device can be attached with loosening shares can.

The rigid attachment of these support tubes has in particular at relative large working widths of the devices (for heavy tractors) the advantage that when used alone the rotary harrow is attached to this with some holding stalks with leaf shares as a track loosely can stay. When the rotary harrow is a certain distance behind the stratified cultivator is coupled, holding sticks with loosening shares can be used both on the cultivator as well as on the rotary harrow in a total of at least two rows - the rear stems offset from the front and staggered in the direction of travel - Can be attached without the sticks remaining on the rotary harrow being transferred would have to be. This means that any compacted soil can be as flat or deep as desired be loosened evenly without causing too large clods of earth and it is not necessary to use wing shares for shallower working depths and larger ones Use the working depth of the blade shares.

However, this has the disadvantage for medium and smaller working widths that e.g. with implement combinations for smaller tractors, where the loosening coulters arranged in at least two rows and one of them in front of the rotating tools the cultivator should always be arranged at a distance in front of the rotary harrow must be, so that the overall combination is still too long and too long for many tractors is heavy to be easily excavated.

In some cases the owner of a smaller tractor can do without the layer cultivator, which can also be used on its own, by the holding handles for the loosening coulters in two Rows at the Rotary harrow attached, one row in front of and one behind the frame of the rotary harrow. this but only makes sense where the soil is blocked by the loosening coulters. loosened deeply and should only be crumbled flat by the rotating prongs, or if it is anyway is already so loose that the rotating tines can crumble the top layer, before the loosening coulters attached behind the frame drive under the soil, be able to lift and loosen.

The invention therefore solves the problem of the device for seedbed preparation, in particular to improve the frame and the trestle so that the equipment combination If necessary, it can be built even lighter and shorter than the one after registration P 34 24 250.3.

The present additional invention solves this problem in that the Additional tube of the cultivator either fixed or height-adjustable in front of the frame the rotary harrow or fixed or height-adjustable via the frame of the rotary harrow is.

The leaf or wing shares can be attached to the single-beam cultivator at any distance next to each other and, more recently, also to each other " Gap ", i.e. staggered in up to three rows in the direction of travel, that some holding sticks for the loosening coulters on the cultivator and some more can be attached to the new rotary harrow.

This enables the tractor's wheel tracks to be easily loosened even if the rotary harrow and / or the seed drill are directly on the tractor power lift is grown.

This also enables the front holding stems to be arranged in such a way large lateral distances so that even with large amounts of straw there is no risk of clogging consists. In addition, this enables the use of blade shares with the for one complete processing required verhm. small "line spacing".

This means that all tools for loosening the soil, preparing the seedbed, Order and care each have the working width of the seed drill, see above that, for the first time, they can all be used either with one another or with the seed drill or other work equipment can be coupled.

So if the soil is only loosened flat, e.g. during stubble cultivation and should be crumbled, can be done with most tractors to the full working width loosened, the seedbed prepared and, for example, also with a top seed drill ordered at the same time.

On the other hand, on heavy, compacted soils it is possible and advantageous to separate both tools from each other and in a first step with the Layer cultivator and extended leaf shares and a possibly coupled combination roller loosen deeply, then only the device for superficial crumbling of the soil to be coupled and with the blade shares attached to this, which are used in the first operation Field strips that have not been loosened, especially the tractor lanes To loosen up, use the rotating tools to crumble the entire top layer flat and sow with a trailed or semi-mounted seed drill.

In both cases, the handrails attached to each device remain and loosening shares unchanged because it does not require tool handles to implement and / or unscrew a share design and another share design to screw on.

Since with this process and these devices for the first time all operations loosening the soil, preparing the seedbed and cultivating and weed control the working width the seed drill are feasible reduces the investment and operating costs of agriculture. Simultaneously the soil tare is improved and harmful tracks in the cultivated field become largely avoided.

The pockets for the handles can either be on the support frame of the device for preparing the seedbed firmly welded on or, if necessary, in different The distances can be adjusted laterally on the additional tubes provided for this purpose - if required also afterwards - be screwed on. They are designed so that the altitude the handlebars are set in the simplest possible way and with plugs or additional screws can be fixed.

Further important features emerge from the description of the drawn Embodiments and from the claims. The invention is based on several, Illustrated in the drawings embodiments explained in such a way that Features that are designated or described in a figure, accordingly, also on other embodiments should be transferable.

They show: FIG. 1: a schematic, partially sectioned side view on an implement for shallow or deep loosening of the soil, e.g. a cultivator, FIG. 2: a corresponding view of an implement with driven tools for seedbed preparation, e.g.

a rotary harrow Figure 3: the corresponding view of the aforementioned devices in the coupled state Figure 4: the side view Figure 5: the top view Figure 6: the partially sectioned side view of an additional frame Figure 7: the partially sectioned side view and Figure 8: the top view of the combination this additional frame with the rotary harrow Figure 8 is a partially sectioned side view and Figure 9: a view from the front of a further embodiment of the rotary harrow shows a perspective partial view of the frame of the rotary harrow with attached, removable headstock with lower link and upper link bracket and extendable lower links mounted on spindles so as to be adjustable in height for attaching a follower device, eg a seed drill.

Figure 10 shows the schematic side view of a rotary harrow with semi-mounted seed drill.

Figure 11 shows the schematic side view of a combination roller with semi-mounted seed drill.

As FIG. 1 shows, the frame 4 of the implement 1 also has the lower link brackets 31 and the upper link bracket 33, for example, two attached tubes 125, in which a threaded spindle is rotatably mounted, the thread of which is in sockets 124 engages, which are provided with an eyelet 130 at the lower end.

On the frame tube 4, both normal handle holders 25 and "cantilevered" Handle holder 131 are attached, so that the holding handles 3 in different Distances attached below, in front of or behind the frame tube 4 and therefore also Can be mounted in two rows, the back row of which goes to the stems the front row is on a gap and is staggered in the direction of travel.

Figure 2 shows the device for crumbling the soil or seedbed preparation, e.g. a rotary harrow 7 with a frame 8, side end shields 52 on which releasably a bearing plate 132 is attached, which the bearing 133 of the rotating Tool carrier 6 with prongs or milling knives 27 receives. At the front of the Bearing shields 133 are side protection plates.

134 removably attached. The middle consoles 26 are spaced apart on the forwardly extended wall 47a of the hollow beam 47 of the frame 8 at intervals welded and take between them welded uprights 120 with trusses 135 connected, of which the upper outside consoles for removable ball eyes 136 and in the middle the top link bracket 137. The middle consoles 26 have a recess 138 for about to the side guided gear shafts and are extended to the front. Your upper edge 26a forms the lower limit of a Niche 123, which is limited to the rear by the uprights 120, in which either If necessary, the frame tube 4 of the implement 1 or an additional frame tube (30) can be attached, and e.g. in by a into hole 139 insertable bolt is rigidly connected. The consoles 26 can through the holes 140 can either be coupled to the implement 1 via lower links or else be connected rigidly or vertically movable with this device. When the implement 7 is to be attached directly to the power lift of a tractor, can be in the holes 140 attachment brackets 142, 141 are attached to the connection point of the lower links to move forward. These attachment brackets can also be designed as handle holders will.

As can be seen from Figure 3, both tools 1 and 7 so firmly but adjustable in height and still releasably coupled together will; that the frame tube of the cultivator is in the niche 123 above the gearbox and the frame of the implement 7 comes to rest, over which the spindle 126 can the rotary harrow below the frame can be made adjustable in height to a limited extent. Holding sticks with loosening shares can be used both in front of the rotary harrow on the cultivator and be mounted on the cultivator behind the rotary harrow.

This results in an extremely short construction and of course also creates the possibility of coupling a second cultivator in front of this combination according to Figure 3 all stalks staggered in two rows and the rear stems on To make a gap to the front stalks.

There are also plans to make this combination option cheaper instead of the layer pit on the rotary harrow according to Figure 4, 5 and 6 a simple tube 30 without lower and upper link brackets to put on the handle holder can be attached to the front and back. This tube 30 can be firmly or detachably connected to the implement 7, so that essentially the same properties of the combination can be achieved as those according to Figure 1-3.

FIG. 8 shows a somewhat modified example of the implement 7 in such a way that the rigid frame tubes are a little deeper, only between the inner consoles 26 and the outer bearing rails are welded, so that on the rotary harrow both the cultivator can be directly attached and housed in the niche can, as well as on the rotary harrow alone, only protruding tool holders to the front and can be attached to the rear. This has the advantage that the rotary harrow itself expanded to a kind of rotor cultivator, i.e. without additional layer cultivator, in particular behind light tugs, with a row or two of tools to be deployed can. The additional frame tubes also serve as the basis for the fastening parts for an attachable seed drill and also in general as a stiffening of the frame the rotary harrow, so that relatively large working widths are very inexpensive and can be created in a weight-saving and space-saving manner.

Figure 9 shows the perspective view of a trestle for the rotary harrow, which differs from the items already described in that it by means of screw-on or weldable Additional pieces also on the frame girders of other machines for seedbed preparation can be retrofitted is and that in the course of such a conversion not only the advantages of the extreme space-saving combination of the layer cultivator and the rotary harrow can be reached, but also without further modification work, extendable lower links with holding spindles for slave devices can be attached.

There is therefore the possibility of using existing prilling machines that are used for Attaching to a three-point linkage of a tractor are intended to be movable in height to be coupled via this lower link.

But there is also the possibility of using seed drills as shown in Figure 10 shown, can be removed from the rotary harrow by means of simple additional devices to saddle up and thereby bring the center of gravity of the overall combination closer to the rear axle of the tractor than is possible with an attached seed drill were.

A particular advantage of this construction is that one and the same seed drill on both the rotary harrow and the combination roller can be attached to in all cases where the rotary harrow is not needed, or in Connection to the rotary harrow is a recompaction of the seedbed created by this is required, with the same seed drill and a short combination to be able to drill with a favorable center of gravity.

When holding sticks are attached to the rear of the frame of the rotary harrow the mouldboard is laid in a second mounting hole behind the frame, so that there is a free space between the frame and the upper edge of the mouldboard arises in which the stems can be guided downwards.

This free space is also used to set up a seed tube Let the seed drill end immediately in front of the mouldboard so that the seeds inserted into the current thrown up by the rotary harrow and then from the Packer or combination roller can be pressed.

But it is also possible to separate the rotary harrow with known per se Attachable additional frame with support rails for normal seed coulters or disc coulters which always remain on the rotary harrow, but are also removable and in whose seed supply line openings are the seed lines of the attached seed drill can optionally be plugged in, so that with this simple combination both Broad sowing as well as drill sowing becomes feasible.

All these advantages allow a reduction in investment costs, a drastic reduction in operating costs, a significant increase in the quality of work and the use of device combinations behind verhm. light tugs, so that the invention represents a substantial advance.
