Plants or plant leaves are cut, usually by means of a cutting device with blades, in particular a rotary cutterhead, on which blades cut the plants or plant leaves.

However, in order to protect the blade, it is necessary to move the blade to the work area when cutting, and to move the blade to the rest area when not in use, and how to realize such a need is a problem to be solved by those skilled in the art.

In order to solve the above technical problem, the present application provides a cutting device 60, by setting the cutting member 20 and the cutter head 10 to rotate relatively, so that the cutter head 10 can rotate to the working area 40 under the action of centrifugal force when rotating, the cutting member 20 can be discharged, and kept at the high gravity center position 302A to cut plants or plant leaves, when the cutter head 10 stops rotating, since the cutting member 20 is connected with the cutter head 10 based on the connecting member 30, and the connecting member 30 is disposed on the cutter head 10 and has the rotation axis 304 forming an included angle with respect to the central axis 101 of the cutter head 10, the cutting member 20 can rotate around the rotation axis 304, so that the cutting member 20 continues to rotate under the action of centrifugal force, and stops when rotating to the stopping area 41 under the action of gravity, so as to realize retraction of the cutting member 20. The cutter 20 is retracted and discharged in a manner that allows the cutter 20 to move to the work area 40 when cutting and to the rest area 41 when not in use.

In a first aspect, referring to fig. 1, 2, 3, and 4, the cutting device 60 provided herein is applied to a lawn mower, which may be a push mower, an intelligent lawn mower robot, a riding lawn mower, or the like. Specifically, the cutting device 60 includes a cutter head 10 and a cutting assembly, and defines a peripheral region of the cutter head 10 in a thickness direction of the cutter head 10 as a work region 40 and a region surrounded by an edge of the cutter head 10 as a rest region 41. The cutting assembly comprises a connecting member 30 and a cutting member 20, the connecting member 30 being arranged on the cutterhead 10 and having an axis of rotation 304 forming an angle with respect to the central axis 101 of the cutterhead 10, the cutting member 20 being connected to the connecting member 30 and being rotatable about the axis of rotation 304. The cutter member 20 is configured, on the one hand, to be positioned in the work area 40 by centrifugal force generated by rotation of the cutterhead 10 and to rotate about the axis of rotation 304 and remain in the high center of gravity position 302A. The cutter 20, on the other hand, is configured to be thrown to the rest area 41 by the inertia of the cutterhead 10 when the cutterhead 10 stops rotating, and to rotate about the rotation axis 304 and remain in the low center of gravity position 302B.

Referring to fig. 4, fig. 4 shows a work area 40 and a rest area 41, the work area 40 being an area outside the range of the in-plane cutterhead 10, and the rest area 41 being an area within the range of the in-plane cutterhead 10.

Referring to fig. 3, fig. 3 shows the axis of rotation 304 of the coupling 30 and the central axis 101 of the cutterhead 10, the axis of rotation 304 being at an angle to the central axis 101. The plane of the cutter 20 as it rotates about the axis of rotation 304 is inclined relative to the central axis 101 of the cutterhead 10, so that the distance of the cutter 20 relative to the cutterhead 10 varies as the cutter 20 rotates about the axis of rotation 304, such that the cutter 20 has different positions of the center of gravity.

Referring to fig. 1 and 2, fig. 1 shows a high center of gravity position 302A of cutter 20, and fig. 2 shows a low center of gravity position 302B of cutter 20. As described above, the distance between the cutting member 20 and the cutterhead 10 is continuously changed, so that the cutting member 20 has different center of gravity positions, the low center of gravity position 302B of the cutting member 20 is set in the parking area 41, and the cutting member 20 automatically rotates to the low center of gravity position 302B around the rotation axis 304 of the connecting member 30 under the action of gravity. The high center of gravity position 302A of the cutter 20 is set in the work area 40, so that the cutter 20 will rotate to the high center of gravity position 302A only when the cutterhead 10 rotates, and the cutting work is performed.

The cutting member 20 may be driven by a motor 90, the driving end of the motor 90 is connected with the center of the cutterhead 10, and the driving end of the motor 90 rotates to drive the cutterhead 10 to rotate, so as to implement the cutting operation of the cutting member 20. When the motor 90 stops, the cutting member 20 moves to the stopping area 41 under the action of gravity, so that the cutting member 20 is protected.

The cutter member 20 is arranged to rotate relative to the cutterhead 10 and the cutter member 20 is connected to the cutterhead 10 on the basis of a connection member 30, the connection member 30 being arranged on the cutterhead 10 and having an axis of rotation 304 forming an angle with respect to the centre axis 101 of the cutterhead 10, the cutter member 20 being rotatable about the axis of rotation 304. On the one hand, the cutter head 10, when rotated, is able to rotate under centrifugal force to the working area 40 and is held in the high center of gravity position 302A to cut plants or plant leaves. On the other hand, when the cutterhead 10 stops rotating, the cutter 20 is caused to continue rotating under centrifugal force and to stop when rotating under gravity to the rest area 41, to effect retraction of the cutter 20. The cutter 20 moves to the work area 40 when cutting and to the rest area 41 when not in use.

Referring to fig. 8, in some embodiments, cutterhead 10 is disposed parallel to the ground, or may be disposed obliquely to the ground.

Referring to fig. 1 and 2, in some embodiments, the coupling 30 includes a coupling shaft 303 and a rotating member 301, the coupling shaft 303 being coupled to the cutterhead; the rotating member 301 is rotatably connected to the connecting shaft 303, and the cutting member 20 is connected to the rotating member 301; the turning member 301 and the connecting shaft 303 are inclined relative to each other, and the center of gravity of the cutting member 20 and the turning member 301 is located at the high center of gravity position 302A in the working area 40 and at the low center of gravity position 302B in the rest area 41.

When the rotating member 301 rotates around the connecting shaft 303, the cutting member 20 is driven to rotate around the connecting shaft 303, and the center of gravity of the cutting member 20 and the rotating member 301 combined is located at the high center of gravity position 302A in the working area 40 and at the low center of gravity position 302B in the parking area 41. When the cutter head 10 is rotated, the cutter 20 and the rotator 301 can be rotated to the high gravity position 302A by centrifugal force and maintained at the high gravity position 302A to cut plants or plant leaves. When the cutterhead 10 stops rotating, the rotating member 301 and the cutting member 20 continue to rotate under centrifugal force and stop when rotated to the low gravity center position 302B under gravity to achieve movement of the cutting member 20 to the working area 40 when cutting and to the rest area 41 when not in use.

The term tilt in the relative tilt of the rotary member 301 and the connecting shaft 303 means that the plane in which the rotary member 301 rotates is inclined relative to the central axis 101 of the cutterhead 10, and the two are included at an angle other than ninety degrees. Meanwhile, the included angle between the central axis 101 and the rotation axis 304 is not limited to ninety degrees.

The term high center of gravity position 302A refers to a position where cutting member 20 and/or rotating member 301 is vertically closest to cutterhead 10 when cutting member 20 and/or rotating member 301 is rotated, and the term low center of gravity position 302B refers to a position where cutting member 20 and/or rotating member 301 is vertically furthest from cutterhead 10 when cutting member 20 and/or rotating member 301 is rotated.

Specifically, the rotating member 301 is fixedly connected to the cutting member 20, and the rotating member 301 is rotatably connected to the connecting shaft 303. The rotary member 301 and the connecting shaft 303 may be fixedly connected, the connecting shaft 303 and the cutterhead 10 may be rotatably connected, and the cutter 20, the rotary member 301, and the connecting shaft 303 may be integrally rotatably connected to the cutterhead 10.

Referring to fig. 1 and 2, in some embodiments, the coupling 30 is coupled obliquely relative to the cutterhead 10, and the cutter 20 is coupled rotatably to the coupling shaft 303.

In the case of a connection of the connection shaft 303 with respect to the cutterhead 10, the term inclined means that the connection shaft 303 forms an angle with the cutterhead 10 that is not ninety degrees.

The link 30 is connected to the cutterhead 10 in a relatively inclined manner such that, when the cutting member 20 is rotated about the link 30, the centre of gravity of the cutting member 20 is in a high centre of gravity position 302A in the working area 40 and in a low centre of gravity position 302B in the rest area 41. So that when the cutterhead 10 rotates, the cutting member 20 can be rotated to the high gravity center position 302A by centrifugal force, when the cutterhead 10 stops rotating, the cutting member 20 continues to rotate by centrifugal force and stops rotating to the low gravity center position 302B by gravity, so that the cutting member 20 moves to the working area 40 when cutting and to the rest area 41 when not in use.

Referring to fig. 3, the rotator 301 includes a supporter 3011 and a bearing 3012, the supporter 3011 includes a connection portion 3011A and an inclined portion 3011B, the connection portion 3011A is connected to the connection shaft 303, the inclined portion 3011B is connected to an outer side wall of the connection portion 3011A and is inclined with respect to the connection portion 3011A, an inner ring of the bearing 3012 is connected to an outer side wall of the inclined portion 3011B and is parallel to the inclined portion 3011B, a sleeve 3013 is sleeved on an outer ring of the bearing 3012, and the cutter 20 is connected to the sleeve 3013.

By providing the bearing 3012 such that the sleeve 3013 is rotatable based on the outer race of the bearing 3012, the cutter 20 is connected to the sleeve 3013, and the cutter 20 is then rotatable relative to the connection shaft 303. The connection portion 3011A is connected to the connection portion 3011A, and the inclined portion 3011B can incline the bearing 3012 with respect to the connection shaft 303 so that the cutter 20 is inclined with respect to the connection shaft 303.
