Description

Die Erfindung betrifft einen Grubber, insbesondere Tiefenlockerer zur Kombination mit einer nachgeordneten zapfwellenangetriebenen Bodenbearbeitungsmaschine gemäß desOberbegriffes des Patentanspruches 1. Ein derartiger Grubber ist beispielsweise durch die deutsche Offenlegungsschrift 3439519 bekannt. Derartige Grubber weisen quer zur Fahrtrichtung schmale Stiele auf, an deren unteren Enden Flügelschare zur Bodenlockerung angeordnet sind. Wenn derartige Grubber zur Tiefenlockerung auf mit Pflanzen oder Stroh bedeckten Flächen eingesetzt werden, setzt sich sehr schnell die sich auf der Bodenoberfläche befindlichen Stroh- und Pflanzenteile an den Grubberstielen fest. Nach kurzer Zeit bauen sich an den Grubberstielen Stroh- und Pflanzenteile auf, so daß der Raum zwischen den einzelnen Grubberstielen sehr schnell. verstopft.The invention relates to a cultivator, in particular subsoiler for combination with a downstream PTO-driven soil cultivation machine according to the preamble of claim 1. Such a cultivator is known, for example, by the German Offenlegungsschrift 3439519. Such cultivators have transversely to the direction narrow stalks, at the lower ends wing shares are arranged to loosen the soil. When such cultivators are used for the purpose of deep loosening on surfaces covered with plants or straw, the straw and plant parts located on the soil surface attach themselves very quickly to the cultivator stalks. After a short time, straw and plant parts build up on the cultivator stems, so that the space between the individual cultivator stems is very fast. clogged.

It has been trying to remedy this situation in this known prior art by the trailing Soil cultivation device, here a tiller to the cultivator stems is arranged so that the cultivator stalks between

den Bodenbearbeitungswerkzeugen der Fräse befinden, so daß die Bodenbearbeitungswerkzeuge die sich evtl. an denthe tillage tools of the mill, so that the tillage tools that may be on the

Remove cultivator stems from accumulating plant and straw parts. However, this solution has many disadvantages. In particular, this solution can not be powered by PTO Implement tillage machines whose tools rotate about upright axles. Furthermore, a further cultivator is known from DE-OS 37 23615. To clog up on this cultivator

zwischen den Grubberzinken und dem Rahmen zu vermeiden, ist vor den Grubberstielen unterhalb des Rahmens eine rotierendebetween the cultivator tines and the frame is a rotating one in front of the cultivator stalks below the frame

Mixing and crumbling roller arranged, which is driven by a transmission of Her PTO of the tractor. adversely

ist bei diesem Vorschlag, daß er sehr teuer und aufwendig ist.is in this proposal that he is very expensive and expensive.

The invention is therefore based on the object to enable in a simple way a constipation-free work of the cultivator,

wobei insbesondere das Festsetzen von Boden oder auf dem Boden befindlichen Teilen, wie Stroh etc. am Grubberstielverhindert werden soll.in particular, the setting of soil or on-ground parts, such as straw etc. is to be prevented on the cultivar handle.

This object is achieved by the characterizing measures of claim 1. As a result of these measures is in the simplest and cost-effective manner by the twisted sideways inclined

zulaufende Scharblatt gewährleistet, daß die an dem Grubberstiel aufsteigenden Pflanzen-, Stroh- oder Bodenteile seitlich amtapered blade ensures that the ascending on the cultivar stem plant, straw or soil parts laterally on

Cultivator stem be steered past. This solution can be with all cultivators or Tiefenlockerern even later

DE-GM 8104456 and DE-OS 3019677 disclose cultivated cultivars. After the German Utility Model 8104456, these rotated cultivator blades are only applied to the outer grubbines to the Keep soil in the work area of the cultivator. In the machine according to DE-OS 3019177 the cultivator blades are twisted,

um den Boden zu wenden. Die erfindungsgemäße Lösung noch der erfindungsgemäß erreichte Vorteil sind bei diesembekannten Stand der Technik erreichbar.to turn the floor. The inventive solution nor the advantage achieved according to the invention can be achieved in this known prior art.

Furthermore, the invention provides in a preferred embodiment, that in the area of the three-point coupling elements Blade sheet is twisted in such a way that the ascending to the blade sheet bottom and / or bottom parts of the lower Three-point coupling connection elements is bypassed. By this measure is a blockage especially in the Middle area of the cultivator avoided. The space here is very narrow, as the space between the cultivator stalks through the Three-point coupling elements is concentrated. By this measure, however, it is achieved here that clogging is reliably avoided in this area.

> Im eine äußerst sichere verstopfungsfreie Arbeit des Grubbers zu gewährleisten, ist erfindungsgemäß vorgesehen, daß anallen Grubberstielen ein in sich verdrehtes Scharblatt zugeordnet ist.> In order to ensure an extremely safe blockage-free work of the cultivator, the invention provides that all cultivated stalks a twisted blade is assigned.

In order to be able to clog safely, even when driving fast, as well as when there is a lot of straw on the ground surface
