Description " DEVICE FOR BROKENING STRANGE WEED " The invention relates to a device for keeping weeds free of crops, especially of row crops such as e.g. Forest seedlings-row crops.

In general, row crops are kept clear by machine chopping weeds. In forest row crops the weeds are often only mowed. However, both measures are associated with considerable disadvantages: There is a risk that crops are damaged. If the soil between the crops is chopped, there is a further danger that the roots of the crops will be damaged. Often, a machine processing the standing in the immediate vicinity of the crop weed is not included, so that the effort is in vain.

But the use of chemistry does not lead to the desired result. Apart from the fact that the use of chemical agents has been increasingly restricted by law, the effect is inadequate, shows side effect for animals and plants, especially for microorganisms such as bees and is also expensive. Regardless of this, the use of chemistry only has a short-term effect and makes regular spray applications necessary.

The prior art is characterized mainly by the machine weed removal by mowing or hacking. For example, DE 1962961 A1 describes a device for mechanically depressing weeds. In practice, however, such a machine has proven to be unusable, especially in the field.

Also, other prior art devices have proven unsuitable for the purpose of weed keeping. Thus, DE 20 2007 004 701 U1 describes a chopping comb with 4 prongs, which is preferably made of steel or aluminum and designed for soil cultivation. Also FR 12 92 638 describes a harrow made of metal, wherein on the metal plate sharp blades are attached. Next is also known from CH 210799 a tool with digging tines for lifting plants. All three tools are intended for tillage but unsuitable for weed removal.

From DE 370174 a rake with interchangeable tines is known. However, the tines are so tight that they are very disadvantageous when weeding down weeds.

The object of the invention is therefore to provide a device for weed-free of row crops, especially of forest seedlings-row crops, with which almost all weeds such as thorn bushes, brambles, etc. are detected and depressed, without damaging crops. Further, the handling should be inexpensive and easy for the user.

Further details, advantages and examples will become apparent from the following description and the embodiment schematically shown in Figures 1 and 2 of a device for depressing weeds.

Fig. 1 shows a device for pushing down weeds in the front view. Fig. 2 shows the device for pushing down weeds in the side view. Fig. 1 shows a device for depressing weeds 10 consisting of a shaft 12 with a handle 14 in T-shape. Alternatively, a handle could be used in D-shape. At the spade stem 12, a sheet 16 is attached. The sheet 16 is substantially triangular in shape; but it is also another form, such as a round or any other weight-saving form conceivable. Preferably, the sheet 16 is made of spruce with a thickness of about 25 mm. In the sheet several tines 18 are embedded in hardwood. In the illustrated embodiment, five prongs 18 are machined into the blade 16 and have an outwardly projecting length of approximately 3 cm. Although the tines could be longer, but in practice this length has proven to be advantageous. The 1/3

Claims (4)

Austrian Patent Office AT 11 227 U1 2010-07-15 the tines 18 is about 10 cm. Also conceivable would be a respective distance in a range of 5 cm to 15 cm. With the illustrated device, weeds are not - as usual cut-off or completely uprooted, but it is bent near the root and pressed smoothly on the ground. With the device described, it is thus possible to suppress weeds in the immediate vicinity of the crop, with the result that it no longer takes away the light crops (light competition). The weeds remain green due to its root adhesion and grow in the horizontal direction, although they are inhibited by the buckling. Unlike mowing and / or hoeing, the inevitable consequences of the formation of new shoots are largely avoided. Another advantage has been found that the kinked and depressed plants form a dense, the soil between the crops covering pad and so among other things due to the lack of light, a root of seeds is prevented. The method described has also proven to be advantageous because the crops are offered by the whereabouts of the depressed weeds optimum growth conditions by the remaining shade moisture at the plant. But not only the drying of the soil is reduced or completely avoided, also the game bite is minimized, because the game does not come so easily to the crops due to the remaining on the ground thorn bushes. Figure 2 shows the device in side view and documents that the tool has a small footprint in the storage in its narrow embodiment. Claims 1.
