[0002] Such harvesting mechanisms are known in the prior art. The installation process of the harvesting mechanism is complicated. A harvesting mechanism that can be easily installed is desired. Summary of the Invention

[0003] The object of the present invention is to provide a harvesting mechanism for a lawn mower and / or a motorized sickle, a lawn mower and / or a motorized sickle having such a harvesting mechanism and a method for installing such a harvesting mechanism and / or such a lawn mower and / or such a motorized sickle, wherein the harvesting mechanism and / or the lawn mower and / or the motorized sickle have correspondingly improved properties.

[0004] The present invention achieves this object by providing a mowing mechanism having the features described below. Furthermore, the object underlying the present invention is achieved by providing a lawn mower and / or a motorized sickle having the features described below. Furthermore, the object underlying the present invention is achieved by providing a method having the features described below.

[0005] The mowing mechanism according to the invention is constructed or configured or arranged for a lawn mower (in particular a robotic lawn mower) and / or a motorized sickle. The mowing mechanism comprises or has at least one tool device, in particular only one (in particular only one) tool connection device and in particular only one (in particular only one) fixing device. The tool device is constructed or configured for cutting grass. The tool connection device is constructed or configured for (in particular immediately or directly) rotation or rotational movement or swivel movement around the (in particular central) mowing mechanism rotation axis of the mowing mechanism. In addition, the tool connection device and the tool device are constructed or configured for a particularly releasable (in particular tool-free and / or non-destructive releasable) form-fitting (in particular immediately or directly) mutual connection for particularly immediately or directly and / or form-fitting fixing of the tool device, in particular a form-fitting connection, to prevent it from being loosened radially (in particular therefore orthogonally) in a radial direction with respect to the mowing mechanism rotation axis from the tool connection device. The fixing device and the tool connecting device are constructed or configured to be adjustably, in particular adjustably movable, at least partially relative to each other, in particular and back in sections along or against at least partially (in particular only) a radial direction between a release position and a fixing position, the release position being used to (in particular immediately or directly) release a form-fitting connection established and / or released, in particular by a user (in particular immediately or directly), and the fixing position being used to fix the form-fitting connection, in particular by a user, in particular immediately or directly and / or form-fittingly, to prevent it from being released.

[0006] This feature (particularly the release position) allows the tool device to be switched (particularly without tools and / or without damage) or replaced (particularly without tools and / or without damage) by the user. Furthermore, this feature (particularly the adjustability or adjustment in or against the radial direction) allows adjustment to be independent of rotation. In particular, a rotation cannot cause a change from the fixed position to the release position without the user or by accident. This therefore achieves a high degree of reliability.

[0007] In particular, the harvesting mechanism may be configured for rotation (in particular instantaneous or direct) about a harvesting mechanism rotation axis.

[0008] The tooling device, the tool connection device and the fixing device may be different.

[0009] When the tool connection device rotates about the axis of rotation of the harvesting mechanism, in particular due to this rotation, the tool device can protrude beyond the outer edge of the tool connection device and / or the fixing device, in particular corresponding in the radial direction. Additionally or alternatively, the tool device can have (in particular is) a cutting tool device, in particular a cutting tool, in particular with at least one cutting blade. Additionally or alternatively, the tool device can be configured for cutting grass in a so-called free cutting method without a matching tool device (in particular a matching blade). Additionally or alternatively, the tool device can be a tool element. Additionally or alternatively, the tool device can be one-piece.

[0010] The tool connection device may be a tool connection element. Additionally or alternatively, the tool connection device may be in one piece.

[0011] The fixing device may be a fixing element. Additionally or alternatively, the fixing device may be in one piece. Additionally or alternatively, the fixing device may be configured to rotate (in particular immediately or directly) around the harvesting mechanism rotation axis.

[0012] The harvesting mechanism can have a shaft receptacle, in particular the tool connection device can have a first shaft receptacle, and / or the fixing device can have a second shaft receptacle, for accommodating the rotational axis, in particular in a non-orthogonal (in particular parallel) axial direction with respect to the harvesting mechanism rotational axis. The shaft receptacle can (in particular the first shaft receptacle can and / or the second shaft receptacle can) define the harvesting mechanism rotational axis. Additionally or alternatively, the harvesting mechanism rotational axis can be a harvesting mechanism longitudinal axis of the harvesting mechanism. Furthermore, additionally or alternatively, "non-orthogonal" can mean that the deviation (in particular angular deviation) with respect to the harvesting mechanism rotational axis is a maximum of 30 degrees (°), in particular a maximum of 20°, in particular a maximum of 10°.

[0013] The release position and the fixed position may be different.

[0014] By adjusting from the release position to the securing position, a positive connection need not be established or may not be established. Additionally or alternatively, by adjusting from the securing position to the release position, a positive connection need not be released or may not be released. In other words, the tool connection device and the tool device can be designed to be connected to each other in a positively locking manner at least in the securing position (in particular, also in the release position).

[0015] The tool connection device and the tool device can be configured for a particularly described and / or releasable (particularly releasable without tools and / or non-destructive) form-fitting mutual connection, for particularly immediate or direct and / or form-fitting fixing of the form-fittingly connected tool device against release from the tool connection device in a radial direction and / or along and / or in a direction of rotation about the axis of rotation of the harvesting mechanism.

[0016] The radial direction may be orthogonal to the (in particular mentioned) direction of rotation about the harvesting mechanism axis of rotation.

[0017] The fixing device and the tool connection device need to be or can be configured to be at least partially (in particular completely) adjustable relative to one another along or counter to the (in particular described) direction of rotation and / or rotation about the axis of rotation of the harvesting mechanism between a release position and a fixing position. Additionally or alternatively, the fixing device and the tool connection device can be configured to be at least partially adjustable relative to one another in translation between a release position and a fixing position.

[0018] An at least partially radial direction may mean that the deviation (in particular the angular deviation) with respect to the radial direction is at most 45°, in particular at most 30°, in particular at most 15°.

[0019] In a refinement of the present invention, the tool device or tool connection device includes or has a pin, a bolt, or a pin. The tool connection device or tool device includes or has a pin receptacle. The pin and the pin receptacle for receiving the pin are constructed or configured for a positive-locking connection, in particular parallel to the pin's longitudinal axis. In particular, the pin's longitudinal axis is non-orthogonal to the harvesting mechanism's rotation axis, in particular parallel. This makes it possible to easily establish a positive-locking connection and / or to rotate the tool device about the pin's longitudinal axis. In particular, the pin receptacle can be a hole, in particular a through hole. Additionally or alternatively, the pin's longitudinal axis can be dispersed and / or need or can be coaxial with respect to the harvesting mechanism's rotation axis. Furthermore, additionally or alternatively, "non-orthogonal" can mean that the deviation (in particular, angular deviation) with respect to the harvesting mechanism's rotation axis is a maximum of 30°, in particular a maximum of 20°, and in particular a maximum of 10°. Furthermore, additionally or alternatively, the pin's longitudinal axis need or can be non-parallel to the radial direction, in particular orthogonal. In particular, "non-parallel" can mean that the deviation (in particular angular deviation) with respect to the radial direction is at least 60°, in particular at least 70°, in particular at least 80°. Additionally or alternatively, the tool device can extend radially away from the pin longitudinal axis at least during a rotation of the tool connection device about the harvesting mechanism rotation axis, in particular by said rotation.

[0020] In a development of the invention, the tool connecting device and the tool device are constructed or configured for a particularly further and / or releasable (especially releasable without tools and / or non-destructive), particularly immediate or direct form-fitting mutual connection at least in the fixing position (especially and in the release position), for particularly immediate or direct and / or form-fitting fixing of the tool device, especially the form-fitting connection, to prevent it from being released from the tool connecting device in, in particular, the first axial direction, which is non-orthogonal (especially parallel) to the axis of rotation of the harvesting mechanism.

[0021] Additionally or alternatively, the fixing device and the tool device are constructed or configured for a particularly immediate or direct form-fitting mutual connection that is particularly releasable (particularly releasable without tools and / or without destruction) (particularly only) in a fixing position, for particularly immediate or direct and / or form-fitting fixing of the tool device, particularly a form-fitting connection, against release from the fixing device in a second axial direction that is non-orthogonal (particularly parallel) to the axis of rotation of the harvesting mechanism and is particularly opposite to the second axial direction and / or the first axial direction.

[0022] Furthermore, additionally or alternatively, the fixing device and the tool connecting device are constructed or configured for a particularly immediate or direct form-fitting mutual connection that is particularly releasable (particularly releasable without tools and / or non-destructively) (particularly only) in a fixing position, for a particularly immediate or direct and / or form-fitting fixing against mutual loosening in particularly at least one, particularly first and / or second axial direction that is non-orthogonal (particularly parallel) to the axis of rotation of the harvesting mechanism.

[0023] In particular, "non-orthogonal" can mean that the deviation (in particular angular deviation) with respect to the axis of rotation of the harvesting mechanism is a maximum of 30°, in particular a maximum of 20°, in particular a maximum of 10°. Additionally or alternatively, in particular, the first or second axial direction needs to be or can be non-parallel, in particular orthogonal, with respect to the radial direction. In particular, "non-parallel" can mean that the deviation (in particular angular deviation) with respect to the radial direction is at least 60°, in particular at least 70°, in particular at least 80°. Additionally or alternatively, a form-fitting connection between the fixing device and the tool device and / or between the fixing device and the tool connection device can be established or established by adjusting from the release position to the fixed position. Additionally or alternatively, a form-fitting connection between the fixing device and the tool device and / or between the fixing device and the tool connection device can be loosened or loosened by adjusting from the fixed position to the release position. In other words: the fixing device and the tool device and / or the fixing device and the tool connection device do not need to or can not be configured for form-fitting connection to each other in the release position. Additionally or alternatively, the form-fitting connection between the fixing device and the tool device and / or between the fixing device and the tool connecting device can be configured to fix (in particular fix and / or cause fixation) the form-fitting connection between the tool connecting device and the tool device, so as to fix the form-fitting connected tool device to prevent it from being loosened from the tool connecting device in the radial direction. Additionally or alternatively, the form-fitting connection between the fixing device and the tool connecting device can be (in particular arranged) in the (in particular corresponding) radially outer half of the fixing device and / or the tool connecting device, in particular at the (in particular corresponding) radially outer edge. This makes it possible to avoid or even prevent external tilting or lifting. Additionally or alternatively, the form-fitting connection between the fixing device and the tool connecting device can be (in particular arranged) near the tool device, in particular at the tool device.

[0024] In a further development, in particular a design, of the present invention, either the tool connection device or the fixing device comprises or has, in particular, only one (in particular, a single and / or circular) cover disk or cover plate. The cover disk is designed or configured for, in particular, immediate or direct rotation or rotational or swivel motion about the harvesting mechanism rotation axis and for covering, in particular, a further positive connection between the tool connection device and the tool device (if provided) and / or between the fixing device and the tool device (if provided) in an axial direction (in particular, the aforementioned) that is non-orthogonal (in particular, parallel) to the harvesting mechanism rotation axis. This protects the positive connection from contact with grass and / or lawn or grass. The cover disk can, in particular, be referred to as a sliding disk. Additionally or alternatively, "non-orthogonal" can mean a deviation (in particular, an angular deviation) of a maximum of 30°, in particular a maximum of 20°, in particular a maximum of 10°, with respect to the harvesting mechanism rotation axis. Additionally or alternatively, the axial direction needs to be or can be non-parallel, in particular, orthogonal, to the radial direction. In particular, “non-parallel” may mean that the deviation (in particular the angular deviation) with respect to the radial direction is at least 60°, in particular at least 70°, in particular at least 80°.

[0025] In a further development of the invention, the fixing device and the tool connection device are constructed or configured to be adjustable relative to each other at least partially in sections between a release position and a fixed position in an axial direction (especially described) that is non-orthogonal (especially parallel) to the axis of rotation of the harvesting mechanism. In particular, the fixing device and the tool connection device are constructed or configured to be adjustable relative to each other at least partially (especially only) in the axial direction in a first adjustment section or adjustment movement section between the release position and the intermediate position, and to be adjustable in a second adjustment section or adjustment movement section (especially different from the first adjustment section) between the intermediate position and the fixed position along or against (especially only) the radial direction. This achieves a particularly high degree of reliability against accidental adjustment from the fixed position to the released position. In particular, the intermediate position can be different from the fixed position and the released position. Additionally or alternatively, a positively locking connection between the fixing device and the tool device (if provided) can be established or established by adjusting from the released position to the intermediate position. Additionally or alternatively, the form-fitting connection between the fixing device and the tool device (if provided) can be released or released by adjusting from the intermediate position to the release position. Additionally or alternatively, the form-fitting connection between the fixing device and the tool connection device (if provided) can be established or established by adjusting from the intermediate position to the fixed position. Additionally or alternatively, the form-fitting connection between the fixing device and the tool connection device (if provided) can be released or released by adjusting from the fixed position to the intermediate position. Additionally or alternatively, "non-orthogonal" can mean that the deviation (especially angular deviation) with respect to the axis of rotation of the harvesting mechanism is a maximum of 30°, in particular a maximum of 20°, in particular a maximum of 10°. Additionally or alternatively, the axial direction needs to be or can be non-parallel, in particular orthogonal, with respect to the radial direction. In particular, "non-parallel" can mean that the deviation (especially angular deviation) with respect to the radial direction is at least 60°, in particular at least 70°, in particular at least 80°.

[0026] In a further development of the invention, the mowing mechanism comprises or has a plurality of tool devices. These tool devices are in particular respectively constructed or configured for mowing. The tool connection device and the tool device are in particular respectively constructed for a particularly releasable (in particular releasable without tools and / or without destruction) form-fitting (in particular immediate or direct) mutual connection, for securing the tool device, in particular connected form-fittingly, in particular immediately or directly and / or form-fittingly, against being released radially (in particular, therefore orthogonally) from the tool connection device in different (in particular corresponding) radial directions with respect to the axis of rotation of the mowing mechanism. The fixing device and the tool connection device are constructed or configured to be at least partially adjustable relative to each other between a release position for (in particular immediate or direct) releasing, in particular immediate or direct establishment and / or release of the form-fitting connection, and a fixing position for securing the form-fitting connection, in particular immediate or direct and / or form-fittingly, against release. This makes it possible to easily establish a form-fitting connection. The tool devices can in particular be of identical construction. Additionally or alternatively, the positively connected tools can be arranged in particular regularly, in particular equidistantly, in the (particularly described) direction of rotation about the harvesting mechanism rotation axis. The radial direction can be orthogonal to the (particularly described) direction of rotation about the harvesting mechanism rotation axis.

[0027] In one embodiment of the invention, the fastening device and the tool connecting device are designed or configured to be adjustable relative to one another completely along or against only a single radial direction, at least in sections, between a release position and a fastening position.

[0028] This allows simple adjustment and / or simple and therefore cost-effective production of the mowing mechanism, in particular the fastening device and / or the tool connection device.

[0029] Alternatively, the fixing device and the tool connection device are constructed or configured to be adjustable in a plurality of parts relative to one another along or against different radial directions, at least in sections, between a release position and a fixing position.

[0030] This allows symmetry, in particular rotational symmetry, of the harvesting mechanism (in particular the fastening device and / or the tool connection device) in the (in particular described) direction of rotation about the harvesting mechanism rotation axis. This allows for simple and therefore cost-effective production of the harvesting mechanism, in particular the fastening device and / or the tool connection device.

[0031] In one refinement of the present invention, in particular a design, in particular either the fixing device or the tool connection device is designed to change at least one (in particular its) dimension or (in particular its) extension, in particular (in particular its) radius, in a radial direction, in particular in different radial directions (if provided), for at least segmental adjustment between a release position and a fixing position. In particular, the dimension can be smaller in the release position, in particular in an intermediate position (if provided), and larger in the fixing position. This provides a particularly high degree of safety against unintentional adjustment from the fixing position to the release position.

[0032] In one embodiment of the present invention, in particular, either the fixing device or the tool connection device includes or has an axial portion and at least one radial portion, in particular directly or indirectly movably connected to the axial portion. The axial portion is designed or configured to be movable, in particular only in an axial direction, in particular non-orthogonal (in particular parallel) to the harvesting mechanism rotation axis, and the radial portion varies in at least a portion of the radial direction, in particular for adjustment relative to one another, in particular for adjustability. In particular, the axial portion and the radial portion may be different. Additionally or alternatively, "non-orthogonal" may mean that the deviation (in particular angular deviation) with respect to the harvesting mechanism rotation axis is a maximum of 30°, in particular a maximum of 20°, in particular a maximum of 10°. Furthermore, additionally or alternatively, the axial direction may or may be non-parallel, in particular orthogonal, to the radial direction. In particular, "non-parallel" may mean that the deviation (in particular angular deviation) with respect to the radial direction is at least 60°, in particular at least 70°, in particular at least 80°. Furthermore, additionally or alternatively, the radial portion may be designed to be adjustable only in the radial direction. This allows for a relatively greater degree of dimensional change. Additionally or alternatively, the axial portion can be arranged (in particular, in the extension of) the harvesting mechanism's axis of rotation. Additionally or alternatively, the radial portion can be arranged, in particular, radially outward from the harvesting mechanism's axis of rotation and / or the axial portion. Additionally or alternatively, the axial portion and the radial portion can be configured such that the radial portion is adjusted by adjusting the axial portion.

[0033] In a refinement of the present invention, in particular a design, either the fixing device or the tool connection device includes or has at least one rotatable joint, in particular a rotating joint or hinge, for adjustment at least in sections between a release position and a fixed position. In particular, the axial portion and the radial portion (if provided) are connected by means of at least one joint so as to be adjustable and movable for dimension changes. In particular, the joint is a film hinge. This allows for simple and therefore cost-effective manufacture of the harvesting mechanism, in particular the fixing device or the tool connection device. Additionally or alternatively, the joint may include a hinge pin. This allows for relatively wear-free and / or relatively smooth adjustment. Additionally or alternatively, the fixing device or the tool connection device may have two rotatable joints for each radial portion—mechanically connected, in particular, by means of an intermediate piece—or multiple, in particular double, rotating joints, in particular multiple rotating joints, in particular double rotating joints. This allows adjustment of the radial portion only in the radial direction. Additionally or alternatively, at least one joint is designed to adjust the radial portion by adjusting the axial portion. Additionally or alternatively, the longitudinal axis of the joint can be non-orthogonal, in particular parallel, to the (particularly described) direction of rotation about the harvesting mechanism rotation axis. In particular, "non-orthogonal" can mean that the deviation (particularly the angular deviation) to the direction of rotation is at most 30°, in particular at most 20°, in particular at most 10°.

[0034] In a further development of the invention, in particular a design, the tool connection device and / or the fixing device, in particular the cover disc and / or the axial portion (if provided) extend away from the axis of rotation of the harvesting mechanism in a radial direction (in particular immediately or directly) at least in the fixing position.

[0035] Additionally or alternatively, the tool connection device and / or the fixing device, in particular the cover disk and / or the axial portion (if provided) completely surround the harvesting means rotation axis at least in the fixing position in the (in particular described) rotation direction around the harvesting means rotation axis.

[0036] In a further development of the invention, the tool connection device comprises or has a (particularly described) first shaft receptacle for accommodating a (particularly described) rotational axis in an (particularly described) axial direction that is non-orthogonal (particularly parallel) to the harvesting mechanism rotational axis. The fixing device comprises or has a (particularly described) second shaft receptacle for accommodating, in particular, the same rotational axis, in particular in an axial direction. The first shaft receptacle and the second shaft receptacle are designed or configured to be adjustably, in particular adjustable, movable relative to one another, in particular along or counter-radial directions and / or along or counter-axial directions, at least in sections, between a release position and a fixing position. This achieves a particularly positive-locking fixing, preventing the first and second shaft receptacles from being adjusted into the release position, in particular into an intermediate position (if provided), in the fixing position, by means of the particularly accommodated rotational axis and / or by means of a fixing element for fixing the harvesting mechanism to the rotational axis in the fixing position. In particular, the first and second shaft receptacles are non-coaxial with respect to the harvesting mechanism rotational axis in the release position, in particular into the intermediate position (if provided). Additionally or alternatively, "non-orthogonal" may mean that the deviation (especially angular deviation) with respect to the axis of rotation of the harvesting mechanism is at most 30°, in particular at most 20°, in particular at most 10°. Furthermore, additionally or alternatively, the axial direction may or may be non-parallel, in particular orthogonal, to the radial direction. In particular, "non-parallel" may mean that the deviation (especially angular deviation) with respect to the radial direction is at least 60°, in particular at least 70°, in particular at least 80°.
