Definitions
- the invention relates to a soil cultivation device.
- the soil cultivation device comprises a frame device and a share unit.
- the share unit is detachably attached to the frame device and can be moved through the ground in a working direction during operation to create a furrow.
- the frame device and the share unit each have at least one first recess which is continuous in a transverse direction angled to the working direction.
- the first recess of the frame device is aligned with the first recess of the share unit about a first recess center axis.
- a first fastening element extends through the first recesses.
- the frame device or the share unit has at least one second recess which is continuous in the transverse direction and has a second recess center axis.
- a second fastening element extends through the second recess.
- the second recess is open to the outside in a longitudinal section in an insertion direction.
- Such a soil cultivation device is known.
- the first fastening element is arranged in the first recesses.
- the second fastening element is inserted into the second Recess.
- the second fastening element creates a force-locking connection between the share unit and the frame device.
- the open second recess is advantageous because it makes the assembly and disassembly of the share unit easier in that it no longer requires the complete removal of the second fastening element from the second recess in the transverse direction.
- a disadvantage of the known soil cultivation device is the lack of reliability of the fastening of the share unit to the frame device, since the share unit swings back around the first recess center axis despite the flow of force, particularly in rough operating conditions.
- the object of the present invention is to provide a generic soil tillage device whose share unit is reliably fixed to the frame device.
- the object is achieved in that the insertion direction in the longitudinal section is angled to a tangential direction that is oriented at right angles to an auxiliary straight line through the two recess center axes.
- This design of the second recess means that the blade unit cannot be pivoted about the first recess center axis, even independently of a frictional connection, as long as the fastening elements extend through the respective recesses.
- the invention With the design according to the invention, the advantages of the second recess that is open to the outside are retained and, with the aid of the fastening elements, a positive connection is achieved between the blade unit and the frame device, particularly in the region of the second recess, preferably at least radially to the first recess center axis. This results in a significantly more reliable fastening of the blade unit to the frame device.
- the soil cultivation device is in particular an agricultural machine.
- the share unit is in particular designed as a share.
- the share unit is in particular designed to be mirror-symmetrical.
- the share unit serves to displace the soil sideways.
- the recesses are preferably arranged above the surface of the soil during operation.
- the frame device and/or the blade unit are/is in particular designed in one or more parts.
- the frame device and/or the blade unit are/is preferably rigid, particularly preferably made of steel.
- a cutting plane of the longitudinal section is preferably arranged parallel to the working direction and vertically.
- a cutting plane of a cross section is preferably arranged parallel to the transverse direction and vertically.
- the transverse direction is in particular oriented at right angles to the working direction.
- the blade unit preferably has the second recess.
- the blade unit particularly preferably has two second recesses and/or two first recesses, which are arranged offset from one another in particular in the transverse direction, wherein in particular each of the sheet metal elements has a first and a second recess.
- the insertion direction is oriented at least partially away from the first recess center axis.
- the insertion direction at least partially coincides with a direction parallel to the auxiliary line, which points away from the first recess center axis.
- the second recess is arranged in front of the first recesses in relation to the working direction.
- the second recess is preferably designed such that it is further away from the ground during operation than the first Recesses. This reduces the risk that soil thrown up by the share unit will wear out the second recess, in particular its edges, which are important for fastening the share unit.
- the second recess center axis is preferably equidistant from both edges and a recess base of the second recess, which is the one furthest inside in the share unit or the frame device.
- the recess base is in particular semicircular in longitudinal section.
- the second recess center axis coincides in particular with a longitudinal center axis of the second fastening element.
- the insertion direction in the longitudinal section is angled to the tangential direction by an angle of at least 30°, preferably at least 50°, particularly preferably at least 70°. This ensures that even with a certain amount of play between the second fastening element and the second recess, only the smallest possible pivoting of the blade unit relative to the frame device about the first recess center axis is possible.
- the first recesses are in particular through-holes.
- the first recesses are preferably completely enclosed by the frame device or the blade unit.
- the first recesses are in particular round in longitudinal sections through the frame device or the blade unit, wherein the first recess center axis runs through the center of the recesses and corresponds to their axis of symmetry.
- at least one of the first recesses is optionally designed to be open to the outside, wherein its insertion direction preferably deviates from the insertion direction of the second recess.
- the first fastening element is preferably designed to be movable relative to the blade unit and/or movable relative to the frame device.
- the first fastening element preferably has a clearance fit within the first recesses.
- the first fastening element is particularly preferably designed as a screw. The advantage of this is that in addition to the positive connection, a frictional connection can also be achieved between the blade unit and the frame device.
- the first fastening element is preferably designed as a bolt or pin, in particular with an axial lock.
- the blade unit or the frame device preferably has a second recess which is aligned with the second recess of the frame device or blade unit around the second recess center axis and which is continuous in the transverse direction. Both the blade unit and the frame device thus each have a second recess, the second recesses being aligned in a similar way to the first recesses. In contrast to the second recess of the frame device or blade unit, the second recess of the blade unit or frame device is preferably completely enclosed, in particular like the first recesses.
- the second fastening element extends through the second recesses. The second fastening element is preferably movable relative to the blade unit and relative to the frame device in the transverse direction. formed.
- the second fastening element is designed as a screw. Even if the second fastening element can be removed from the second recesses, it can remain in the second recess of the share unit or the frame device during assembly or disassembly of the share unit due to the open design of the second recess of the frame device or share unit. Alternatively, the second fastening element is enclosed by the share unit or frame device, whereby the number of parts that can move relative to one another is reduced.
- the frame device comprises in particular a one-piece frame element, in particular designed as a cast part.
- the first recess of the frame device and the second recess of the frame device are preferably formed in the frame element. Because both recesses are formed in the same component of the frame device, they can be positioned more precisely relative to one another, which results in a more resilient connection of the share unit to the frame device.
- the soil tillage device preferably comprises a first cover element which, in particular with respect to the working direction, rests laterally against the share unit or the frame device.
- the first cover element preferably has a first recess into or through which the first fastening element extends.
- the first cover element has a second recess into or through which the second fastening element extends.
- the first The recess and/or the second recess of the first cover element preferably have an internal thread.
- the first cover element enables a large-area axial force to be applied to the frame device or the blade unit.
- the internal thread also makes nuts for the fastening elements, which are preferably designed as screws, superfluous.
- the first cover element allows the blade unit to be dismantled, in particular the first fastening element to be removed, with just a single wrench and without any additional tools.
- the soil tillage device preferably has a second cover element which rests laterally on the share unit or the frame device opposite the first cover element.
- the second cover element has a first recess through which the first fastening element extends.
- the second cover element in particular has a second recess through which the second fastening element extends.
- screw heads of the fastening elements rest on a lateral surface of the second cover element, wherein the fastening elements have a clearance fit within the second cover element.
- the second cover element is in particular opposite the first cover element in that at least part of the share unit and at least part of the frame device is arranged between the cover elements.
