Definitions
- the invention relates to a tillage tool, in particular a Grubbergrindl, for field construction with a mounting portion and a directly or indirectly adjoining thereto working part.
- Grubbergrindl with integrated working part are used in field construction for seed preparation and to loosen the soil. They have a working part, which is equipped with an end-side cutting edge. An arcuate arm, which can be attached to a tool carrier, is connected to the working part. During work, the working part engages deep into the soil. In order to safely derive the occurring high bending moments, the arcuate arm is relatively solid. The working part is exposed to the abrasive attack of the soil, so that the tillage tool must be replaced when it reaches the end of life. It is an object of the invention to provide a soil working tool of the type mentioned, which is wear-optimized and designed application optimized.
- attachment portion of the soil working tool has two mutually spaced support surfaces which are part of a support, in particular a Einhticianmat.
- a tool separation is carried out, wherein the strong wear attack exposed working part is carried out separately from the actual machine attachment part (for example, the arcuate mounting arm).
- the stable coupling succeeds easily over the attachment portion which is formed with the support or the Einhnaturegen. Consequently, during use of the soil cultivation tool according to the invention can be easily attached to the machine attachment part and fixed thereto. The forces occurring during operation can be reliably removed via the spaced support surfaces. Mitteis the support distance high torques can be reliably absorbed. If the machining tool is worn, it can easily be replaced and dug out of the support, in particular the suspension connection.
- the actual machine attachment part can remain attached to the machine and continue to be used. As a result, a wear system is created, which is wear-optimized and designed application-optimized by the quick-change system.
- a preferred embodiment of the invention is such that at least one of the support surfaces is arched, in particular convex, at least in section.
- a defined contact with the support adjusts the working stuff! is grown produce.
- an approximately linear Stützstelie can be realized, which allows a reproducible clamping connection.
- a convex geometry is used.
- a concave geometry in particular a dimple on the working part, is used.
- a curved geometry may also be provided on the supporting part.
- both the support member and the working part at their support surfaces form curved geometries (convex or concave), which then lie against each other in operational use.
- the support surfaces may be arranged at a distance from one another transversely to the tool feed direction, so that a load-optimized design of the suspension connection is achieved.
- the support surfaces are arranged at an angle to one another, preferably in the range between> 0 ° and 90 °. In this way, a backlash-free clamping of the tillage tool can be achieved. At this angle, jamming of the suspension connection is prevented, so that even when penetrated into the Einhssentell soil the suspension connection can be reliably solved always.
- the attachment portion is a Koppeltei! having a hook-like projection.
- the hook-like projection on the one hand, a slight hooking can be made even in rough labor.
- the loading forces can be positively transmitted via the hook-like projection.
- the hook-like projection preferably has the first support surface, so that a compact design is achieved. If it is additionally provided that the hook-like projection forms a cross-sectionally wedge-shaped formed projection, then a play-free clamping of the coupling part on the machine attachment part can be achieved.
- An inventive tillage tool may be such that the attachment portion has a spacer which holds the supporting surfaces supporting parts to each other at a distance.
- the spacer receives the bending stress between the two support surfaces and may be constructed with its cross section corresponding to have a high equatorial resistance torque against bending.
- the spacer preferably in the feed direction, a greater height than transverse to the feed direction.
- the bending stress of the spacer can also be adjusted by the distance dimension of the two support surfaces to each other.
- the coupling part of the soil working tool may comprise a Einhlindage, which may be arranged in particular adjacent to the hook-like projection to form a toothed portion.
- a hook mount guarantees a positive connection.
- the toothed assignment of the tillage tool to the machine support member creates a positive connection.
- the coupling part has a side surface pointing in the opposite direction to the tool feed direction, which is at an angle, preferably at an obtuse angle, to the second support surface.
- the side surface can also be used to support against the machine attachment part, so that a reduction in the surface load of the two support surfaces is achieved.
- a securing receptacle may be provided.
- a bolt, a clamping ring or the like can be put through.
- the object of the invention is also achieved with a carrier for receiving a soil working tool according to one of claims 1 to 11.
- the carrier serves as a machine attachment part and takes the soil working tool interchangeable.
- it may be provided that it has a fixing portion, which is followed by a support portion via a transition portion having a receptacle for forming the Einhnaturevig. This results in a simple and stable design of the recording in that it is recessed in the support member.
- the tillage tool can then be easily mounted in the carrier when the receptacle is opened in the feed direction.
- the receptacle in the feed direction is delimited by a front approach.
- the approach takes a form-fitting at least a portion of the processing forces that are introduced via the tillage tool.
- the inclusion of two extending in the direction of the side parts can be limited. These side parts prevent a transverse offset of the tillage tool.
- FIG. 2 shows the Grubbergrindl of FIG. 1 in a perspective front view
- FIG. 5 is an enlarged view of the detail taken from FIG. 4 and marked V-V, FIG.
- FIG. 6 is an enlarged view of a detail taken from FIG. 4 and designated therein by VI.
- Fig. 1 shows a Grubbergrindl having a carrier 10 and a replaceable with this connectable tillage tool 42- 20.
- the design of the carrier 10 can be taken from Fig. 4 in more detail.
- the carrier 10 has a fixing section 1, which is provided with two attachment receptacles 12 designed as bores. Instead of the holes, other fastening receptacles 12 can be used.
- the fixing section 11 is used for coupling the Grubbergrindls to a conventional tool carrier.
- the fixing section 11 is followed by a coupling section 13 via an arcuate support member 15.
- the coupling section 13 is at right angles to the fixing section. A suitable other angle assignment is also conceivable.
- the coupling section 13 has an end-side support part 14.
- a receptacle 14.6 is recessed front.
- the receptacle 14.6 has an opening which opposite to the feed direction V (see FIG. 4) is accessible.
- the receptacle extends 14.6 over the entire width of the coupling portion 13.
- the carrier 10 can therefore be easily manufactured as a burning or forged part. It is also conceivable that the receptacle 14.6 extends only over part of the width. Even then, a simple production is possible as a forged part and the closed side of the receptacle 14.6 offers without additional parts cost a defined system for the tillage train. Laterally, the receptacle 14.6 of two side panels 30 is limited (see also Fig.
- a projection 14.3 is provided below the opening of the receptacle 14.6 , which protrudes tooth-like. It is also conceivable that no recessed recording 14.6 is used. In this case, the hook-like projection 14.3 may be arranged projecting on the support member 11.
- the bottom 14.4 merges into a contact section 14.5, which extends transversely to the feed direction V.
- the projection 14.3 forms a support surface 14.7 in the transition region to the bottom 14.4.
- the projection 14.3 is followed by a surface 14.2 at the front. This extends transversely to the feed direction V.
- the surface 14.2 merges into a further support surface 14.1, which is at an obtuse angle to the surface 14.2.
- a tillage tool 20 can be exchangeably connected to the carrier 10.
- the soil working tool 20 has a fastening section 21, to which a working part 22 is integrally formed.
- the working part 22 is opposite to the feed direction V with a rear side 22.1 completed, the arcuately formed in the region of the free end of the tillage tool 20 forms a rounding transition 22.2.
- a receiving portion 22.3 is formed, which is concave.
- 6 shows the detail marked VI in FIG. 4 in an enlarged view.
- the working part 22 ends with an end piece 23.
- the end piece 23 has a support surface 23.1, which is employed at an angle ⁇ 90 ° to the feed direction V.
- the support surface 23.1 merges into a rounding region 23.2, which in turn terminates in the rounding transition 22.2.
- a cutting element 24 is fixed, in particular festgelötet.
- the cutting element 24 consists of a hard material, in particular tungsten carbide.
- the cutting element 24 has a connecting part 24.1, which is placed with its flat surface on the support surface 23.1 and fixed thereto, for example, is soldered. On its free surface, the cutting edge is formed with a discharge surface 24.2, which is convex for the purpose of better Schneidgutab Koch. In addition, more hard material is positioned in the region of the free end of the working part 22 with the convex shape, so that more wear volume is available here.
- the discharge surface 24.2 merges into a cutting edge 24.3, which is also convexly formed with a radius of curvature in order to achieve a sharp-edged cutting engagement.
- the cutting edge 24.3 is adjoined by an open space 24.4, which in turn merges flush with the rear side 22.1 of the working part 22 via a connecting piece 24.5.
- the flush transition represents a wear-optimized tool design and prevents the abrasive attack on the working part 22.
- the Anschiussteil 24.5 is based on an end bearing surface 23.2 of the end piece 23 and is attached thereto, in particular soldered.
- a non-angular, in particular plate-shaped, cutting element can be installed, in which case this cutting element with its plate edge forms the cutting edge.
- the working part 22 is equipped with guide elements 25 in the region of its front receiving area 22.3.
- the guide elements 25 are also made of hard material and serve on the one hand the improved wear protection of the working part 22. On the other hand, they reduce the penetration resistance of Grubbergrindls in favor of lower required machine performance, since they provide for optimized material flow.
- Fig. 5 shows the configuration and arrangement of the guide elements 25 in enlarged detail.
- the guide elements 25 are U-shaped in cross-section. They have a groove 25.1, to which via transition sections 25.2 side parts 25.3 are formed. The side parts 25.3 are spaced apart and include between them the groove 25.1 a.
- the channel 25.1 is flush with the discharge surface 24.2 of the cutting element 24, so that no disturbing and wear-promoting paragraphs are formed.
- FIG. 3 shows that a multiplicity of guide elements 25 are mounted flush against one another and are fastened to the front of the working part 22. With this segmentation, the risk of breakage of the individual guide elements 25 compared to a one-piece or large-scale guide element is significantly reduced and an additional processing of the HM seat is avoided.
- the tilling tool 20 has a fastening section 21.
- the attachment portion 21 comprises a projection 21.1, which is hook-shaped and forms the part of a Einhnaturegen.
- the hook-like projection 21.1 terminates opposite to the feed direction V with a molding surface which is transverse to the feed direction V runs and passes over a rounding 21.2 in an upper, extending in the feed direction V deck section.
- the front section of the deck section is adjoined by a chamfer, which merges into a front-side forming surface.
- the hook-like projection 21.1 is integrally formed on a coupling part 21.3.
- the coupling part 21.3 forms immediately adjacent to the hook-like projection 21.1 a Einh briefly 21.7 in the form of a tooth gap.
- the hook-like projection 21.1 defines with a support surface 21.8 the Einh briefly 21.7.
- the support surface 21.8 is arranged obliquely to the feed direction V, in particular at an obtuse angle to the feed direction V.
- Opposite the hook-like projection 21.1 the Einh briefly 21.7 is limited with a side surface 21.5.
- the side surface 21.5 is part of a spacer 21.4. 4 shows that the working part 22 of the soil working tool has a further support surface 21.6. This is at an angle to the side surface 21.5 and the support surface 21.8.
- the angle assignment is chosen according to the angle assignment between the support surfaces 14.1 and 14.2.
- the support surface 14.1 is equipped with a slightly convex curvature.
- the tilling tool 20 is inserted with its hook-like projection 21.1 through the front opening into the receptacle 14.6.
- the tillage tool 20 is slightly tilted relative to the carrier 10.
- the tilling tool 20 is then pivoted into the receptacle 14.6 simultaneously with a vertical lowering movement superimposed on the tilting movement oriented in the opposite direction to the feed direction V.
- This assembly movement is due to the tooth-like connection between the hook-shaped projection 21.1, the Einh briefly 21.7 on the one hand and the Approach 14.3 of the carrier 10 or the adjacent to the approach 14.3 arranged recess on the other hand limited.
- Fig. 4 shows the assembled state.
- a securing receptacle 26 is introduced into the working part 22.
- the fuse holder 26 is formed as a bore.
- the securing receptacle 26 is aligned with a securing receptacle in the side parts 30.
- a securing element for example a clamping sleeve, can be passed through the aligned securing receptacles, for example holes, and thus the tillage tool 20 can be securely fixed to the carrier 10. This is supported by the further support surface 21.6 with its convex curvature on the support surface 14.1 and the support surface 21.8 on the support surface 14.7.
- the Grubbergrindl is moved in the feed direction V.
- a resistance force is introduced into the working part 22 via the soil, which acts on the Grubbergrindl, which is oriented opposite to the feed direction V.
- This reaction force is removed by the tillage tool 20 by means of the support surfaces 21.6 and 21.8 in the associated support surfaces 14.1 and 14.7.
- the cutting element 24 cuts into the ground.
- the cut soil flows over the guide elements 25.
- the soil working tool 20 must be replaced.
- the carrier 10 can usually remain on the machine because it is exposed to little or no wear.
- the working part 22 with a deviation of ⁇ 50% to the same width as the support member.
- This low resistance forces can be achieved during operation. This reduces the required machine train performance; there are only narrow furrows for the introduction of the seed or the fertilizer and the interface between the working part 22 and support member is less burdened.
