Description

The present invention relates to a quick-change system of a soil tillage implement having the features of independent claim 1.

In order to achieve the desired result in agricultural tillage, the farmer or the user a variety of different load-working equipment such as cultivators or tines or the like. Available. Such tools can be equipped with a variety of tillage tools and Scharsystemen. To create a way to equip the tools each with the desired Scharsystem, various quick change systems can be present on tillage tools. With such systems, a simple and fast exchange of share systems to the tillage tools to be done. A possibility should also be created to replace worn shearing systems accordingly quickly and easily against not worn shearing systems. Such quick-change systems are already known from the prior art, for example. Through the EP 2 591 650 A1 and the EP 1 872 643 B1 ,

The known from the prior art quick-change systems each include tillage tools consisting of a tine handle and a share system arranged thereon, on each of which a share or a share tip or the like. Sharpening tools are releasably attached. The shares or share points can each be solved or mounted in the lower part of the share system via a quick-change system from the tine handle. However, such systems also have a number of disadvantages. So must u.a. depending on the coulter system, in each case several individual coulters are changed. As a result, each individual share must be equipped with a quick-change system. Also move in such Scharsystemen the coulters and the components of the quick-change system during field work in the soil or in the soil, whereby these components are subject to wear. Due to this, the components may no longer fulfill their function. Likewise, a simple change of components is no longer possible.

Another quick change system is the DE 10 2012 107 476 A1 described. The tine handle, on which the sharpening tools are mounted, is divided into two and consists of an upper and a lower segment. The upper segment has mounting holes for attaching the tine stem to a rocker arm of a bias unit. The desired shares are mounted on the lower segment. Both segments are connected via a fastening portion, which is composed of two mutually spaced support portions.

With such a system, although the quick change system is simplified, since only the lower segment must be replaced and not each share. The tine handle, however, still consists of several parts. In addition, the upper segment must be connected via a screw with the rocker of the biasing unit, which in turn increased parts costs and thus incur higher costs.

The object of the invention is to provide a quick-change system of a tillage tool available, which is optimized parts and application optimized. These objects are achieved by a quick-change system having the features of independent claim 1. Further advantageous embodiments are described by the subclaims.

Thus, the invention proposes a quick-change system of a tillage tool, in which the quick-change system or the interface is no longer between a tine handle and a crowd in a lower, located during field work in the ground area. Rather, the interface is directly between a rocker example. A bias unit and a coulter arranged. This can be achieved that the parts cost is largely minimized and the components of the quick-change system are no longer subject to wear.

Thus, the invention provides a tillage tool available, as this example, can find use in agricultural tine harrow, cultivator or the like. The tillage tool is equipped with a quick change system for the respective shares. The tilling tool can be connected, for example, by means of various flange elements with a frame or support structure of the agricultural machine. The flange elements may be screwed to the frame construction, but also inextricably connected, for example, by means of a weld. Other connection or flange elements would be conceivable. In a preferred embodiment, the flange element consists of several parts and is composed, for example, of a housing and a clamping angle, so that by clamping the two parts, preferably by means of screws, the flange is clamped to the frame structure. On the housing or on the flange element are at least two, Arranged transversely to the direction of travel joint axes or joint parts, by means of which a variable in length of the biasing member and a rocker are each mounted pivotably. The biasing member is pivotally connected at its front end to the housing or the flange element and with its rear end to the rocker again by means of hinge pins or joint parts. The biasing member may be biased and define a corresponding biasing force or trigger force with which a coulter unit of the harrow is pulled through the ground. If this release force, for example, exceeded by obstacles in the ground, the biasing member changes its length and the coulter unit can avoid the obstacle in the ground.

The rocker has in its course a quick-change system, which includes an interface so that a share unit can be connected to the rocker. The coulter unit is formed, for example, by a tine and / or one or more coulters. In order to prevent the components of the quick-change system from moving in the ground during field processing and thus becoming worn, the interface is located above and / or immediately below a center of a common hinge axis or articulation part of the flange element and the rocker arm. In a preferred embodiment, the lowest position of the interface or the quick-change system is at a distance with the dimension A, measured between the center of the joint axis and the farthest from this position of the interface. The dimension A is equal to or less than half of the distance of measure B measured between the center of the common hinge axis and the deepest point of the coulter unit. The dimension A and B is measured in each case as a vertical with respect to a direction of travel and measured in each case between the center of the joint joint axis of the flange element and rocker and the lowest position of the interface or the lowest point of the coulter. In a preferred embodiment, this dimension A is less than or equal to one third of the dimension B, from which the following conditions may result: Dimension A ≤ 1/2 × dimension B respectively.: Dimension A ≤ 1/3 × dimension B

Thus, i.a. ensures that no components of the quick-change system move during field travel in the ground or in the ground, whereby they are not subject to wear. Likewise, no additional tine handle is needed because the interface is mounted directly between the coulter and swingarm.

The interface has at least two mutually spaced support sections. The support portions are designed such that the share unit and the rocker at least partially form a positive connection.

The rocker and the coulter unit can, for example, have a circular-arc-shaped cutout or a circular-arc-shaped projection or vice versa. These can be followed by a vertical surface, which forms the first support portion. Further, the interface and the coulter unit may each have a directionally inclined or a direction perpendicular to the direction of travel surface, which is spaced from the vertical surface. This inclined or vertical surface forms, for example, the second support section.

The support sections can be designed in many ways and have a variety of surfaces and contours. The support sections are each designed such that the axial forces acting on the interface can be accommodated and no further fastening elements or the like are required. The support sections may be formed by an inclined and / or substantially vertical and / or largely vertical and / or substantially horizontal surface in the working direction. Also, at least partially arcuate contours would be conceivable as a support surface.

In order to secure the coulter unit against a lateral or a displacement transversely to the direction of travel, the interface may have lateral plates and / or a bolt fastening and / or the like means. For bolt fastening can, for example, holes or the like. Be provided in the components of the interface. Thus, it can be ensured that the coulter unit does not migrate out of the interface by axial forces acting on the coulter unit, or that this, for example, hook-like projection does not escape from the hook-like cutout, but also that, in the case of an embodiment without hook-like elements, this does not migrate downwards can. As a bolt, for example, Federsplinte or screws or the like. Use can be found. This type of connection can form a frictional connection, so that the interface or the quick-change system can be composed of a positive connection and a frictional connection. Likewise, this compound can also be designed in the form of a positive connection, so that the interface is composed of two form-locking connections.

Another embodiment of the interface or the quick-change system could be a suspension connection. This can also have two support sections, wherein the support sections can represent two, for example, in the direction of travel inclined surfaces. The suspension connection may have a hook-like projection, so that the share unit can be hooked into a hook-like cutout of the rocker. Also conceivable would be an opposite arrangement, ie a section in the rocker and a projection in the share unit.

The coulters can be permanently connected to the tine handle, for example by means of soldering or welding or gluing or the like. Also conceivable would be releasable screw or bolt connections.

The share units can have a variety of design options, these each having an interface with preferably two support sections. The share units usually consist of a tine handle with a variety of detachably and / or non-detachably arranged flocks or share elements. The coulters can be mounted on the front side or on the side of the tine.

In the following, embodiments of the invention and their advantages with reference to the accompanying figures will be explained in more detail. The proportions of the individual elements to one another in the figures do not always correspond to the actual size ratios, since some shapes are simplified and other shapes are shown enlarged in relation to other elements for better illustration.

For the same or equivalent elements of the invention are in the 1 to 4 in each case identical reference numerals used. Furthermore, for the sake of clarity, only reference symbols are shown in the individual figures, which are required for the description of the respective figure. The illustrated embodiments are only examples of how the quick-change system according to the invention can be designed and do not represent a final limitation.

1 shows a tillage tool 10 as this example, in agricultural tine harrows, cultivators or the like. Can be used. The tillage tool 10 has a quick change system 12 up and over a flange element 14 with a frame construction indicated here 16 , which, for example, transversely to the direction of travel 18 extends, mounted. In general, agricultural tine harrow or cultivator are a plurality of such tillage tools 10 at regular intervals to each other and, for example, arranged distributed over several rows. The flange element 14 is made in the embodiment of a housing 20 and a clamping angle 22 together, by means of screws 24 on the frame construction 16 is clamped. This assembly has the advantage that the tillage tool 10 Can be moved transversely to the direction of travel, for example, to obtain other pitches. In addition to a mountable design of the flange elements 14 However, it would also be conceivable that these are fixed to the frame construction 16 are welded. Also would be various other flange elements 14 conceivable or usable.

At the housing 20 or on the flange element 14 are transverse to the direction of travel 18 arranged joint axes or joint parts 26 a variable in its length biasing element 28 and a swingarm 30 each pivotally mounted. The biasing element 28 or the biasing unit is designed in the embodiment as a compression spring. Also conceivable would be other biasing elements, for example. Hydraulically or pneumatically preloaded cylinder or the like. At the rear end of the rocker 30 is the rear end of the biasing element 28 again by means of hinge axis or hinge part 26 swivel mounted.

The swingarm 30 has an interface in its course 32 on, at the one flock unit 34 formed by a tine handle 36 and / or one or more crowds 38 , is mounted.

Further details of the quick-change system according to the invention 12 go from the side view of the tillage tool 10 of the 2 out. The tillage tool 10 is by means of a flange 14 with a frame construction 16 connected. At the housing 20 the flange element 14 are about joint axes or joint parts 26 pivotally a biasing element 28 and a swingarm 30 appropriate. At the rear end of the swingarm 30 is the rear end of the biasing element 28 again by means of a hinge axle or hinge part 26 swivel mounted.

The quick change system 12 includes an interface 32 which is between the swingarm 30 and the share unit 34 is arranged. The interface 32 indicates at its lowest position 41 measure A on, measured between the center 40 the common hinge axis 26 the flange element 14 and the swingarm 30 and the lowest position 41 the interface 32 , Said distance is less than or equal to one third of the distance measure B. The measure B is measured between the center point 40 the common hinge axis 26 the flange element 14 and the swingarm 30 , to the lowest point 42 the share unit 34 , The dimension A and B are each as vertical with respect to a direction of travel 18 and each between the center 40 the common hinge axis 26 from flange element 14 and swingarm 30 as well as the lowest position 41 the interface or the lowest point 42 sowing unit 34 measured.

This results in the following relationship for the arrangement of the interface: Dimension A ≤ 1/3 × dimension B.

It would also be conceivable that the ratio would be, for example, half, so that this could be represented as follows: Dimension A ≤ 1/2 × Dimension B.

This ensures, among other things, that there are no components of the quick-change system 12 move during field work in the soil or in the soil, so that they are not subject to wear. Likewise no additional Zinkenstiel is needed, since the interface 32 directly between share unit 34 and swingarm 30 is arranged.

the interface 32 of the 2 also has two spaced apart support sections 44 on. These support sections 44 are designed so that the share unit 34 and the swingarm 30 at least partially form a positive connection or that they have at least in sections the largely same contour.

The swingarm 30 and the share unit 34 First, each have a circular arc-shaped section 46 or a circular arc-shaped projection 48 on which a vertical surface adjoins and which the first support section 44 forms. Next point the interface 32 and the share unit 34 each one inclined in the direction of travel surface 50 which is spaced from the vertical surface. This inclined surface 50 forms the second support section in the embodiment 44 ,

The support sections 44 can be designed in many ways and have a variety of surfaces and contours. The support sections 44 are each formed so that these are the axial forces 52 , which by moving the share unit 34 through the floor to the interface 32 act, can absorb. Likewise, no further fasteners or the like are required for this purpose.

To the share unit 34 against a lateral or a displacement transversely to the direction of travel 18 can secure the interface 32 have lateral plates and / or a bolt fastening and / or the like means (see. 1 ). For bolt fastening can, for example, holes 54 or the like in the components of the interface 32 be provided. As a bolt, for example, not shown here Federsplinte or screws or the like. Use. Thus, it can also be ensured that the share unit 34 not by axial on the coulter unit 34 acting forces 52 from the interface 32 herauswandert or that the example. Hook-like projection does not die out of the hook-like cutout, but also that in an embodiment according to the 2 without hook-like elements the share unit 34 can not move down.

This type of connection can form a frictional connection, so that the interface 32 or the quick-change system 12 can be composed of a form-locking and a frictional connection. However, two form-locking connections would also be conceivable.

The 3 shows a side view of another embodiment of the quick-change system 12 or the interface 32 at the share unit 34 , The share unit 34 has a tine handle 36 and coulters arranged thereon 38 or scratch elements 38 on. the interface 32 is designed as a suspension connection and also has two support sections 44 , wherein the support sections 44 as two in the direction of travel 12 inclined surfaces 50 are formed. The suspension connection has a hook-like projection 48 on, causing the coulter unit 34 can be hung in a hook-like neck of a swingarm.

It would be different than in 2 and 3 shown, an opposite arrangement, so a section 46 on the swingarm 30 and a lead 48 at the share unit 34 ,

To the share unit 34 against a lateral or a displacement transversely to the direction of travel 18 and wandering out of the hook-like projection 48 secure, has the interface 32 a bolt fastening. This is at the interface 32 a hole 54 intended.

The coulters 38 are in the example listed insoluble with the tine handle 36 , For example, connected by means of soldering, welding, gluing or the like. As well However, detachable screw or bolt connections would also be conceivable.

The 4 shows a further embodiment possibility of the coulter unit 34 , The share unit 34 points as an interface 32 a hook-like projection 46 with two mutually spaced support sections 44 on. The share unit 34 consists of a tine handle 36 with detachable and / or inseparable arranged flocks or crowd elements 38 , That's how it shows 4 a share unit 34 at the on a zinc stick 36 tilling elements 38 are permanently attached. Thus, for the most varied applications, the most diverse share units 34 conceivable, which in each case over the interface 32 or the quick-change system 12 with the swingarm 30 or the tillage tool 10 can be connected.

The invention has been described with reference to a preferred embodiment. However, it will be apparent to those skilled in the art that modifications or changes may be made to the invention without departing from the scope of the following claims.
