Description

The invention relates to a construction for the placement, adjustable introduction of liquid fertilizers, in conjunction with so-called short disc harrow for tillage in agriculture. The invention relates to a construction that can be mounted on any agricultural disc harrow to optimize manure introduction. Here, a special construction is attached to the front, which on the one hand leads to the deployment unit and the towing vehicle remain relatively clean and on the other hand, the liquid fertilizer but placed in the ground can be stored without this is, as in the known systems especially sticky Soils and humid conditions cause blockages.

Due to the EU's Ammonia and Water Framework Directive, manure and liquid fermentation residues must be directly and directly incorporated in Germany in the future, so that ammonia volatilization and flooding into surface waters does not occur, which currently leads to sometimes severe nitrate pollution in waters in many regions of Germany. in other countries, the focus is on optimal nutrient utilization, and in the Netherlands these procedures have been mandatory for 22 years. For this purpose, so-called short disc harrows are widely used to incorporate manure and digestate directly into the soil. For dominant crops, however, farmers have only a limited amount of time available to growers, which means that the periods of application and incorporation are getting shorter and shorter, because, for B. may be applied before maize only within a maximum of 4 weeks. This means working in conditions that are not always optimal. Therefore, all additional equipment that lead to blockages on the machine to judge problematic, as this cause downtime or even make the use impossible, this has z. B. for contractors serious economic consequences, since the life of a so-called self-driver, even under good conditions per operating hour for the WA 600 ECO from the company Holmer at about 80, - €.

Furthermore, it is very important that the application manure and digestate can be done with a so-called deposit storage, so that the efficiency is correspondingly high, because the difference to a broad-based training is seen in more yields of 10 to 15% (TU Munich to 2004 to 2008) , Correspondingly low is the nitrate shift into the groundwater, because there is no strong nitrification.

It is known that in the Netherlands or Germany for some years already short disc harrows are used for manure spreading. Some of the machines used are only equipped or retrofitted with slurry systems from manufacturers. But there are also complete machines on the market such. B. offered by the company to Zunhammer.

• 1. direkt vor den Scheiben senkrecht auf den Boden auflaufen (z. B. Syn-Cult von Vogelssang, Torric Evers Agro) sodass die flüssigen Dünger breitflächigen eingearbeitet werden, dies hat zur Folge das ist zu einer Feuchtigkeitsanreicherung kommt die in der zweiten Reihe der Bodenbearbeitungswerkzeuge bzw. an der Walze zu Verklebungen oder/und zur Störung der Bodenstruktur führen, der einzige Vorteil dieser Systeme liegt darin das im Prinzip sich die Scheibenelement es frei drehen können ohne dass die Durchgang eingeengt wird. Nachteil dieses Systems die Maschinen werden stark verschmutzt ebenso das Träger Fahrzeug. Bei diesem Verfahren gibt es auch keinen Depotdüngeeffekt, und diese Art wird in einigen Ländern bereits nicht mehr als Gülleinjektion bei eventuellen Förderprogrammen akzeptiert.

Oder über ein Rohr oder Gummitülle direkt auf dem einzelnen Halter der ersten Scheibenreihe in die geöffnete Rille in den Bodenlaufen, dies hat zwar den Vorteile des Depotdüngeeffektes, führt aber regelmäßig zu Verstopfungen der Scheibenhalter und somit zu Verschleiß und unnötigen Standzeiten für die Reinigung.

The systems currently available leave the liquid fertilizer, either

• 1. emerge directly in front of the slices perpendicular to the ground (eg Syn-Cult from Vogelssang, Torric Evers Agro) so that the liquid fertilizers are incorporated over a wide area, this leads to a moisture accumulation that comes in the second row of the Tillage tools or on the roller lead to sticking and / or disturbing the soil structure, the only advantage of these systems is that in principle the disk element can rotate it freely without the passage is restricted. Disadvantage of this system the machines become heavily polluted likewise the carrier vehicle. There is also no depot fertilizer effect with this method, and in some countries this species is no longer accepted as manure injection in any funding programs.
• 2. Or via a pipe or rubber grommet directly on the single holder of the first row of discs in the open groove in the floor running, while this has the advantages of Depotdüngeeffektes, but regularly leads to blockages of the disc holder and thus to wear and unnecessary downtime for cleaning.

Starting from the prior art (0003), it is the object of the present invention to improve the operational safety, environmental compatibility, performance and efficiency of short disc harrows in manure injection.
