For example, the hand-held plant trimming device can be a hand-held mower, and the mower can trim a lawn so that the height of the grass is equal to or close to the specified height, thereby improving the flatness of the lawn.

[0003] The plant trimming device comprises a cutting mechanism for cutting plants and a moving mechanism based on wheels. The cutting mechanism and the moving mechanism can be relatively fixed, and the moving mechanism can drive the cutting mechanism to move, so that the cutting mechanism cuts plants in different areas. When the ground in the area where the plant trimming device operates is uneven, the height of the cutting mechanism is synchronized with the height of the moving mechanism, so that when the cutting mechanism passes through part of the area, the interval distance between the part of the cutting mechanism for cutting plants and the ground deviates from the preset distance, resulting in that the height of part of the trimmed plants deviates from the specified height, and the plant trimming effect is poor.

Rather, the words "exemplary" or "for example" are used in the specific manner to present the relevant concept.

[0111] Please refer to Figure 1 , Figure 1 A plant trimming device 100 provided by the embodiments of the present application is shown. The plant trimming device 100 can be used to cut plants planted on the ground to achieve garden repair or municipal repair, etc.

[0112] It can be understood that the plant trimming device 100 can be a hand-held device, and a worker can control the position for hand-holding on the plant trimming device 100 to limit the moving direction of the plant trimming device 100, so as to trim the plants in a specified area in a specified direction.

[0113] In the embodiments of the present application, the type of the plant trimming device 100 is not specifically limited. For example, the plant trimming device 100 can be, but is not limited to, a hand-held mower, etc.

[0114] As Figure 1As shown, in this embodiment, the plant trimming device 100 may include a frame 10, a moving mechanism 20, a cutting mechanism 30, an electrical control mechanism 40, a support arm mechanism 50, and a handrail mechanism 60. The cutting mechanism 30 is mounted on the first side of the frame 10 and is used to cut plants. The moving mechanism 20 is mounted on the frame 10 and located on the second side of the cutting mechanism 30. The moving mechanism 20 is used to contact the ground and can support the frame 10 to maintain a gap between the frame 10 and the ground. The moving mechanism 20 is used to drive the plant trimming device 100 to move. The electrical control mechanism 40 is mounted on the frame 10 and is used to trigger the operation of the moving mechanism 20 and the cutting mechanism 30. The support arm mechanism 50 is mounted on the second side of the frame 10, and the handrail mechanism 60 is mounted on the support arm mechanism 50. The handrail mechanism 60 is spaced apart from the frame 10.

[0115] It is understood that when the plant trimming equipment 100 is working, the electrical control mechanism 40 triggers the cutting mechanism 30 and the moving mechanism 20 to work, and the operator can adjust the moving direction of the plant trimming equipment 100 through the handrail mechanism 60, so that the plant trimming equipment 100 moves towards the area where the plant to be cut is located.

[0116] It is understood that the first side and the second side can be two opposite sides in the first direction. In the embodiments of this application, the first direction is not specifically limited. For example, the first direction can be... Figure 1 The X direction and its opposite direction are defined, with the side the X-direction arrow points to being the first side and the side the X-direction arrow turns away from being the second side.

[0117] For example, Figure 1 A second direction and a third direction are also shown in one embodiment of this application. The second direction may be... Figure 1 In the Y direction and its opposite direction, the third direction can be Figure 1 The Z-direction and its opposite direction.

[0118] It is understood that the first direction, the second direction, and the third direction can be three intersecting directions in pairs. In the embodiments of this application, the relative relationships of the first direction, the second direction, and the third direction are not further specifically defined. For example, the first direction, the second direction, and the third direction can be three mutually perpendicular directions.

[0119] Please refer to the following: Figure 2In the embodiment, the moving mechanism 20 can include a moving driver 21, a transmission box 22 and a plurality of traveling wheels 23. The transmission box 22 is fixedly installed on the frame 10 at a side facing the ground. The traveling wheels 23 are rotatably connected with the transmission box 22, and are used to abut against the ground. The plurality of traveling wheels 23 are arranged at intervals. The moving driver 21 is fixedly connected with the transmission box 22. A transmission assembly is arranged in the transmission box 22, and is rotatably connected with a driving end of the moving driver 21 and fixedly connected with the traveling wheels 23. When the moving driver 21 works, the rotating end of the moving driver 21 rotates, and in response to the rotation of the output end of the moving driver 21, the transmission assembly moves and drives the traveling wheels 23 to rotate synchronously, so as to realize the movement of the plant trimming device 100.

[0120] It can be understood that the rotatable connection can be a connection mode in which two components are connected through a rotating connecting piece, so that the two components can have relative circumferential movement. In the embodiments of the present application, the type of the rotating connecting piece is not specifically limited. For example, the rotating connecting piece can include, but is not limited to, a bearing, a hinge, a hinge, a rotating shaft, etc.

[0121] In the embodiments of the present application, the installation position of the traveling wheel 23 is not specifically limited. For example, the number of the traveling wheels 23 is two, and the two traveling wheels 23 are respectively located at two ends of the transmission box 22 in the third direction.

[0122] In the embodiments of the present application, the composition of the transmission assembly is not specifically limited. For example, the transmission assembly can include, but is not limited to, a clutch, a transmission, a transmission shaft, a differential, etc.

[0123] It can be understood that the moving driver 21 is an electronic device having a function of driving a rotating body. In the embodiments of the present application, the type of the moving driver 21 is not specifically limited. For example, the moving driver 21 can be a motor.

[0124] For example, the moving driver 21 can be a motor, and the output end of the moving driver 21 is an output shaft of the motor.

[0125] In the embodiments of the present application, the installation position of the moving driver 21 is not specifically limited. For example, one end of the transmission box 22 can protrude from the side of the frame 10 in the third direction, the moving driver 21 can be fixedly installed at the end of the transmission box 22 protruding from the side of the frame 10, and the moving driver 21 is located at the side of the transmission box 22 away from the ground.

[0126] In the embodiments of the present application, the fixing mode of the fixed connection and the fixed installation is not specifically limited. For example, the fixing mode can include screw fixing, welding fixing, mortise and tenon fixing, etc.

[0127] Please refer toFigure 3 In the embodiment, the cutting mechanism 30 is connected with the rack 10 through the rotating mechanism 70. The rotating mechanism 70 can include a fixed rod 71 and a knuckle bearing 72. The fixed rod 71 is fixedly connected with the cutting mechanism 30. The length direction of the fixed rod 71 can be the same as the third direction. The knuckle bearing 72 is fixedly installed on the first side of the rack 10. The knuckle bearing 72 is sleeved on the fixed rod 71.

[0128] It can be understood that at least part of the fixed rod 71 is circular in cross section, and the knuckle bearing 72 is connected with the part of the fixed rod 71 which is circular in cross section.

[0129] In the embodiment, the fixed rod 71 can realize relative rotation with the rack 10 through the knuckle bearing 72, and the axial direction of the rotation center axis of the fixed rod 71 intersects with the second direction and the third direction. For example, the axial direction of the rotation center axis of the fixed rod 71 can be the same as the first direction.

[0130] It can be understood that the knuckle bearing 72 is a spherical sliding bearing, and its sliding contact surface is an inner spherical surface and an outer spherical surface, and it can rotate and swing at any angle when moving.

[0131] In the embodiment, the knuckle bearing 72 is a knuckle bearing 72 whose rotation function is limited in part directions. For example, the knuckle bearing 72 is limited in rotation along the circumferential direction of the knuckle bearing 72, i.e. limited in rotation with the axial direction of the knuckle bearing 72 as the rotation center axis, wherein the axial direction of the knuckle bearing 72 is the same as the third direction. The fixed rod 71 connected with the knuckle bearing 72 cannot realize rotation with the axial direction of the third direction as the rotation center axis.

[0132] It can be understood that the connection of the fixed rod 71 and the knuckle bearing 72 can realize the relative rotation of the fixed rod 71 and the rack 10, so as to realize the relative rotation of the cutting mechanism 30 and the rack 10. The cutting mechanism 30 can rotate relative to the rack 10, and when the cutting mechanism 30 rotates through the rotating mechanism 70, the axial direction of the rotation center axis of the cutting mechanism 30 is the same as the first direction.

[0133] Please refer to Figure 4In the embodiment, the cutting mechanism 30 can include a first connecting frame 31, a second connecting frame 32, a supporting assembly 33, and a trimming device. The first connecting frame 31 is fixedly connected with the fixed rod 71, so as to be relatively rotatably connected with the rack 10 through the fixed rod 71 and the joint bearing 72. The second connecting frame 32 is relatively rotatably connected with the first connecting frame 31, and the rotation center axis of the second connecting frame 32 relative to the first connecting frame 31 intersects with the rotation center axis of the first connecting frame 31 relative to the rack 10. The trimming device can be installed on the second connecting frame 32. When the plant trimming device is placed on the ground, the trimming device is arranged in a spaced-apart manner from the ground. The trimming device is used for cutting the plants on the ground, so that the height of the plants remaining on the ground is equal to or close to the interval distance between the trimming device and the ground.

[0134] For example, the axial direction of the rotation center axis of the second connecting frame 32 relative to the first connecting frame 31 can be the same as the third direction.

[0135] It can be understood that the cutting mechanism 30 can further include the supporting assembly 33, which is used for abutting against the ground and can move relative to the ground and the second connecting frame 32.

[0136] In the embodiment, the type and composition of the trimming device are not limited. For example, the trimming device can include a cutting tool 34 and a traction assembly 35, which can be installed on the second connecting frame 32. The cutting tool 34 is located on the side of the traction assembly 35 close to the ground. The traction assembly 35 is used for rotating and driving the plants to be cut to move synchronously, so that the plants move or maintain the tendency to move towards the cutting tool 34. The cutting tool 34 is connected with the second connecting frame 32, and is used for cutting the plants moving synchronously with the traction assembly 35. The cutting tool 34 is located on the side of the traction assembly 35 facing the ground. The supporting assembly 33 is used for abutting against the ground and supporting the cutting mechanism 30.

[0137] When the plant trimming device 100 is placed on the ground, the supporting assembly 33 and the moving mechanism 20 abut against the ground, the cutting tool 34 maintains a state of being spaced apart from the ground, and the traction assembly 35 maintains a state of being spaced apart from the ground. The interval distance between the traction assembly 35 and the ground can be greater than the interval distance between the cutting tool 34 and the ground. The interval distance between the cutting tool 34 and the ground can be equal to the height that the plants to be cut need to reach.

[0138] In the embodiment, the traction assembly 35 can include a rolling cutter 351 and a traction drive 352. The traction drive 352 is fixedly installed on the second connecting frame 32. The rolling cutter 351 is rotatably connected with the second connecting frame 32, and the driving end of the traction drive 352 is fixedly connected with the rolling cutter 351. The traction drive 352 is used to drive the rolling cutter 351 to rotate. When the rolling cutter 351 rotates, the plants are attached to the rolling cutter 351 and keep the tendency of synchronous movement with the rolling cutter 351. The side of the rolling cutter 351 facing the ground abuts against the cutting tool 34.

[0139] It can be understood that the traction drive 352 is an electronic device having the function of driving the plants to rotate. In the embodiment of the present application, the type of the rotating drive is not specifically limited. For example, the rotating drive can be, but is not limited to, a motor.

[0140] For example, the traction drive 352 can be a motor, and the driving end of the rotating drive is the output shaft of the motor.

[0141] Please refer to Figure 5 It can be understood that the rolling cutter 351 can include a shaft 353, a plurality of connecting discs 354 fixedly installed on the shaft 353, and a plurality of cutter heads 355 fixedly installed on the connecting discs 354. The plurality of connecting discs 354 can be arranged in the axial direction of the shaft 353. The connecting disc 354 is a disc. The cutter head 355 is a long strip-shaped cutter. The length direction of the cutter head 355 intersects with the length direction of the shaft 353, and the length direction of the cutter head 355 intersects with the direction in which the diameter of the connecting disc 354 is located, so as to realize the inclined arrangement of the cutter head 355. Each of the plurality of cutter heads 355 is fixed with the plurality of connecting discs 354. The plurality of cutter heads 355 are arranged in the circumferential direction of the connecting disc 354. The shaft 353 of the rolling cutter 351 can be rotatably connected with the second connecting frame 32 and fixedly connected with the driving end of the traction drive 352. Among the plurality of cutter heads 355 of the rolling cutter 351, the cutter head 355 closest to the ground abuts against the cutting tool 34.

[0142] Please refer to Figure 6 For example, when the plant trimming device 100 works, the rotating direction of the rolling cutter 351 can be the clockwise direction shown in Figure 5

[0143] ​It can be understood that the sharpness of the cutting heads 355 of the rolling cutter 351 is lower than that of the cutting tool 34. When the plant trimming device 100 is working, the rolling cutter 351 rotates, and the cutting heads 355 of the rolling cutter 351 can abut against or form incisions in the plants to be cut and be located in the incisions; the cutting heads 355 rotate with the central shaft 353, thereby driving the plants abutting against and being incised by the cutting heads 355 to move synchronously, so that the plants move along the clockwise direction to approach the cutting tool 34. The plant trimming device 100 is driven by the moving mechanism 20 to move, so that the plants moving synchronously with the cutting heads 355 abut against and are cut by the cutting tool 34.

[0144] The height of the plants cut and saved on the ground is equal to or close to the height of the cutting tool 34 from the ground. The cut parts of the plants can enter the gaps between the multiple cutting heads 355 of the rolling cutter 351 to continue to rotate synchronously with the rolling cutter 351 and be separated from the rolling cutter 351 under the action of the centrifugal force. In this way, through the cooperation of the rolling cutter 351 and the cutting tool 34, the cutting of the plants can be realized, so that the height of the plants on the ground is equal to or close to the interval distance of the cutting tool 34 from the ground.

[0145] It can be understood that, through the relative rotationally connected between the second connecting frame 32 and the first connecting frame 31 and the relative connection between the first connecting frame 31 and the rack 10, the rotation of the second connecting frame 32 and the cutting tool 34, the support assembly 33 and the traction assembly 35 connected to the second connecting frame 32 in two directions (for example, rotation with the third direction as the rotation center axis and rotation with the first direction as the rotation center axis) can be realized, and the movable connection of the second connecting frame 32, the cutting tool 34, the support assembly 33 and the traction assembly 35 with the rack 10 can be realized. Since the transmission box 22 is fixedly connected with the rack 10, the second connecting frame 32, the cutting tool 34, the support assembly 33 and the traction assembly 35 realize the movable connection with the moving mechanism 20.

[0146] Obviously, when the ground of the area where the plant trimming device 100 is working is uneven, the height of the moving mechanism 20 changes with the driving of the moving mechanism 20. At this time, the second connecting frame 32 can move relative to the frame 10 and the moving mechanism 20 with the driving of the moving mechanism 20, so that the change of the height of the moving mechanism 20 does not affect the height of the second connecting frame 32, the cutting tool 34, the supporting assembly 33 and the traction assembly 35, thereby reducing the probability that the supporting assembly 33 of the cutting mechanism 30 cannot keep close contact with the ground when the ground of the area where the plant trimming device 100 is working is uneven, so as to reduce the probability that the distance between the cutting tool 34 and the traction assembly 35 and the ground changes. When the plant trimming device 100 works on all positions in the working area, the height of the plants remaining on the ground is equal to or close to the interval distance between the cutting tool 34 and the ground, i.e. equal to or close to the specified height. In this way, the consistency and flatness of the height of the trimmed plants can be improved, and the plant trimming effect can be improved.

[0147] Please continue to read Figure 4 In the embodiment, the second connecting frame 32 can include a receiving frame 321, a first protruding shaft 322 and a second protruding shaft 323. The receiving frame 321 is provided with a first space 324, and the hob 351 is at least partially received in the first space 324. The first space 324 extends through the first side and the side close to the ground of the second connecting frame 32. The cutter head 355 of the hob 351 can extend out of the first space 324 from the side close to the ground of the first space 324 and abut against the cutting tool 34.

[0148] The first protruding shaft 322 is protruded on the inner wall of the receiving frame 321, and the second protruding shaft 323 is protruded on the inner wall of the receiving frame 321. The first protruding shaft 322 and the second protruding shaft 323 are spaced apart in the first direction and / or the second direction. The central shaft 353 of the hob 351 is rotatably connected with the first protruding shaft 322. The axial directions of the first protruding shaft 322 and the second protruding shaft 323 can be the same as the third direction. The first connecting frame 31 is rotatably connected with the second connecting frame 32 through the first protruding shaft 322.

[0149] In some scenarios, the cutter head 355 of the hob 351 can extend out of the first space 324 from the first side and abut against the plants on the ground. When the hob 351 rotates, the plants are moved to the cutting tool 34 for cutting. The cut parts of the plants continue to rotate with the hob 351 into the first space 324 and move out of the first space 324 from the first side of the first space 324 under the action of the centripetal force.

[0150] In some other scenarios, the cutter head 355 of the cutter 351 does not protrude from the first side of the first space 324, and the plants on the ground enter the first space 324 as the plant trimming device 100 moves, the cutter 351 in the first space 324 rotates to drive the plants entering the first space 324 to move to the cutting tool 34 for cutting. The cut parts of the plants continue to rotate into the first space 324 with the cutter 351 and move out of the first space 324 from the first side of the first space 324 under the action of the centripetal force.

[0151] It can be understood that the inner wall of the receiving frame 321 for closing the first space 324 from the second side can block the cut parts of the plants. The plants moving to the second side of the cutting mechanism 30 are reduced, thereby improving the cleanliness of the mechanisms of the plant trimming device 100 except the cutting mechanism 30.

[0152] In the embodiments of the present application, the number of the first connecting frames 31 is not specifically limited. For example, the first connecting frames 31 can be spaced apart in the third direction by two, and both of the first connecting frames 31 are fixedly connected with the fixed rod 71.

[0153] In the embodiments of the present application, the number of the first convex shafts 322 and the second convex shafts 323 is not specifically limited, for example, the number of the first convex shafts 322 and the second convex shafts 323 can both be two. The two first convex shafts 322 are respectively located on the inner walls of the two ends of the receiving frame 321 in the third direction, the two second convex shafts 323 are respectively located on the inner walls of the two ends of the receiving frame 321 in the third direction, and the two first connecting frames 31 are respectively connected with the two first convex shafts 322.

[0154] Please refer to Figure 7 In the embodiments, the first connecting frame 31 can include a connecting ring 311 and a first extension 312. The connecting ring 311 is sleeved on the first convex shaft 322 and is relatively rotatably connected with the first convex shaft 322. A limiting groove 313 is formed on the connecting ring 311, and the second convex shaft 323 is located in the limiting groove 313. The second convex shaft 323 can relatively move with the connecting ring 311 in the direction of rotation of the connecting ring 311 when the connecting ring 311 rotates. The first extension 312 protrudes from the peripheral wall of the connecting ring 311 and is fixedly connected with the fixed rod 71.

[0155] It can be understood that the fixed connection of the first extension 312 with the fixed rod 71 realizes the relatively rotatable connection between the first connecting frame 31 and the rack 10. The relatively rotatable connection of the connecting ring 311 with the first convex shaft 322 realizes the relatively rotatable connection between the second connecting frame 32 and the first connecting frame 31.

[0156] It can be understood that the extension length of the limiting groove 313 in the rotation direction of the connecting ring 311 limits the movement length of the second protruding shaft 323 in the limiting groove 313. When the second protruding shaft 323 moves to the end of the limiting groove 313 and abuts against the inner wall of the limiting groove 313, the relative rotation of the first connecting frame 31 and the second connecting frame 32 can be limited. In this way, the cooperation of the limiting groove 313 and the second protruding shaft 323 can realize the rotation limitation of the second connecting frame 32, the support assembly 33 connected to the second connecting frame 32, the cutting tool 34, and the traction assembly 35, thereby reducing the probability of large-angle swing of the second connecting frame 32 and the mechanism connected to the second connecting frame 32 when the plant trimming device 100 is transported or assembled, reducing the probability of personal injury or mechanism damage when the second connecting frame 32 and the mechanism connected to the second connecting frame 32 swing at a large angle. The safety of the plant trimming device 100 can be improved, and the service life of the plant trimming device 100 can be prolonged.

[0157] It can be understood that when the number of the first connecting frame 31 is two, the number of the connecting ring 311 and the first extension part 312 is also two. The two first connecting rings 311 can be respectively sleeved on the two first protruding shafts 322, and the two first extension parts 312 can be fixedly connected to the two ends of the fixed rod 71 in the third direction.

[0158] In an embodiment, the cutting tool 34 can be fixedly connected to one side of the containing frame 321 close to the ground and abut against the cutter head 355 close to the ground of the hob 351.

[0159] Please refer to Figure 6 and Figure 8In another embodiment, the cutting mechanism 30 can further include a third connecting frame 36. The third connecting frame 36 can include a first connecting rod 361, a second connecting rod 362, and a first elastic member 363. The first connecting rod 361 can be fixedly connected to the receiving frame 321 on a side of the receiving frame 321 away from the ground, and the first connecting rod 361 can pass through the side of the receiving frame 321 away from the ground. The length direction of the first connecting rod 361 can be the same as the first direction. One end of the second connecting rod 362 can be movably connected to the first connecting rod 361, and the first connecting rod 361 can pass through the end of the second connecting rod 362. The second connecting rod 362 can be rotatably connected to the receiving frame 321, and there is a gap between the connection point of the second connecting rod 362 and the receiving frame 321 and the connection point of the second connecting rod 362 and the first connecting rod 361. The cutting tool 34 can be fixedly connected to the end of the second connecting rod 362 close to the ground, and the cutting tool 34 can be located on the side of the connection point of the second connecting rod 362 and the receiving frame 321 away from the first connecting rod 361. The first elastic member 363 can be located between the end of the second connecting rod 362 passed through by the first connecting rod 361 and the part of the first connecting rod 361 passing through the receiving frame 321. The first elastic member 363 can be used to elastically deform under the extrusion of the second connecting rod 362 and the receiving frame 321, so as to drive the second connecting rod 362 to rotate relative to the receiving frame 321 by the elastic force generated by the elastic deformation, so as to make the cutting tool 34 move synchronously to abut against the rolling cutter 351, or make the cutting tool 34 maintain the trend of moving close to the rolling cutter 351, so that the cutting tool 34 continuously abuts against the rolling cutter 351.

[0160] It can be understood that the second connecting rod 362 can be provided with an opening for the first connecting rod 361 to pass through, and the opening for the first connecting rod 361 to pass through can be provided with a size greater than the diameter of the first connecting rod 361.

[0161] It can be understood that the second connecting rod 362 rotatably connected to the receiving frame 321 can drive the cutting tool 34 to rotate based on the principle of a lever under the action of the elastic force of the first elastic member 363. In this way, when there are foreign matters such as soil and gravel on the ground close to the rolling cutter 351 and the cutting tool 34, the cutting tool 34 can rotate under the pushing of the foreign matters to overcome the elastic force of the first elastic member 363, and after the foreign matters are separated from the cutting tool 34, the cutting tool 34 can be restored to abut against the rolling cutter 351 under the action of the elastic force of the first elastic member 363, so as to reduce the damage to the cutting edge of the cutting tool 34 or the cutter head 355 of the rolling cutter 351 caused by the fact that the cutting tool 34 cannot move when the foreign matters close to the cutting tool 34 due to the rigid connection between the cutting tool 34 and the second connecting frame 32.

[0162] In the embodiments of the present application, the type of the first elastic member 363 is not specifically limited. For example, the first elastic member 363 can be, but is not limited to, a spring. The first elastic member 363 can be sleeved on the first connecting rod 361.

[0163] Please refer to Figure 9 and Figure 10 In some embodiments, the first connecting frame 31 can further include a second extending portion 314. The second extending portion 314 protrudes from the first side of the first extending portion 312. The extending direction of the second extending portion 314 can be the first direction and the second direction, which protrude from the first side of the connecting ring 311 and away from the ground.

[0164] The plant trimming device 100 can further include a box 80. The box 80 is hollow and the second side of the box 80 is open. The end of the box 80 is provided with a slot 81. The second extending portion 314 can be inserted into the slot 81, thereby completing the connection between the box 80 and the first connecting frame 31.

[0165] It can be understood that the second side of the box 80 corresponds to the first side of the first space 324. In this way, when the plant cutting part is rotated by the rotation of the cutter 351, and the plant cutting part is rotated to the first side of the first space 324, the plant cutting part can be removed from the first space 324 and enter the box 80 from the second side under the action of centrifugal force, so that the box 80 realizes the collection of the cutting plant waste.

[0166] It can be understood that the moving direction of the second extending portion 314 when inserted into the slot 81 can deviate from the first direction. In the embodiments of the present application, the moving direction of the second extending portion 314 when inserted into the slot 81 is not specifically limited. For example, the moving direction of the second extending portion 314 when inserted into the slot 81 can be the direction towards the first side of the cutting mechanism 30 and away from the ground.

[0167] It can be understood that when the number of the first connecting frame 31 is two, the number of the second extending portion 314 is two. Two slots 81 can be provided on the box 80, and the two slots 81 are spaced apart in the third direction and are respectively used for inserting the two second extending portions 314.

[0168] Please refer to Figure 4 and Figure 6 In some embodiments, the support assembly 33 can include a first support roller 331 and a second support roller 332. The first support roller 331 is rotatably connected to the receiving frame 321 and located on the first side of the receiving frame 321. The second support roller 332 is rotatably connected to the receiving frame 321 and located on the second side of the receiving frame 321. The first support roller 331 and the second support roller 332 can abut the ground, thereby achieving the support of the cutting mechanism 30.

[0169] The circumferential wall of the first supporting roller 331 is provided with a plurality of accommodation grooves 333, which are arranged along the axial direction of the first supporting roller 331.

[0170] It can be understood that the axial direction of the first supporting roller 331 and the second supporting roller 332 can be the same as the third direction.

[0171] It can be understood that the first supporting roller 331 is located on the first side of the cutting tool 34 and the hob 351, and the second supporting roller 332 is located on the second side of the cutting tool 34 and the hob 351. When the plant trimming device 100 is working, the first supporting roller 331 first passes through the area where the plants to be cut are located. At this time, the plants on the ground can at least partially pass through the accommodation grooves 333, reducing the plants that are pressed down by the first supporting roller 331 and cannot contact the hob 351 and cannot be cut by the cutting tool 34. After the cutting tool 34 completes the cutting of the plants, the second supporting roller 332 passes through the area where the cut plants are located again and presses the cut plants along the first direction, improving the flatness of the cut plants and thus improving the trimming effect on the plants.

[0172] In some embodiments, the first supporting roller 331 and the second supporting roller 332 are directly connected to the receiving frame 321 through the rotating connecting piece.

[0173] Please refer to Figure 11 , in other embodiments, the second connecting frame 32 further comprises an adjusting frame 325. The adjusting frame 325 can comprise a first adjusting seat 326, a first connecting seat 327 and a first adjusting piece 328. The first adjusting seat 326 is fixedly installed on the first side of the receiving frame 321, and the first adjusting seat 326 is spaced apart from the cutting tool 34 in the second direction. The first adjusting seat 326 is provided with a first sliding groove 329. The first connecting seat 327 is at least partially located in the first sliding groove 329, and the end of the first connecting seat 327 close to the ground is provided with a first connecting seat 327. The first connecting seat 327 and the first sliding groove 329 are connected in sliding connection along the second direction. The first supporting roller 331 and the end of the first connecting seat 327 extending out of the first sliding groove 329 are connected in relative rotation. The first adjusting piece 328 penetrates the first adjusting seat 326 and enters the first sliding groove 329. The first adjusting piece 328 is located at the end of the first connecting seat 327 away from the ground. The first adjusting piece 328 and the first adjusting seat 326 are connected in relative rotation, and are threadedly connected with the first connecting seat 327. The rotation of the first adjusting piece 328 can drive the first connecting seat 327 to move in the second direction, thereby adjusting the height of the second connecting frame 32.

[0174] It can be understood that the rotation of the first connecting seat 327 connected with the first sliding slot 329 is limited by the inner wall of the first sliding slot 329, so that when the first adjusting member 328 rotates, the first connecting seat 327 can move along the first sliding slot 329 in the second direction, and the first supporting roller 331 is synchronously moved, so that the second connecting frame 32 is relatively moved in the second direction relative to the first supporting roller 331. In this way, the height of the second connecting frame 32 can be adjusted by adjusting the first adjusting member 328, so that the distance between the cutting tool 34 and the ground is adjusted. The worker can adjust the first adjusting member 328 according to the height of the cut plant that needs to be reached, so that the distance between the cutting tool 34 and the ground is adjusted to the height of the cut plant that needs to be reached.

[0175] For the embodiments of the present application, the number of the adjusting frames 325 is not specifically limited. For example, the number of the adjusting frames 325 can be two, and the two adjusting frames 325 are arranged in the third direction with a distance, and the two first connecting seats 327 in the two adjusting frames 325 are respectively connected with the two ends of the first supporting roller 331 in the third direction.

[0176] Please refer to Figure 1 and Figure 12 In some embodiments, the electric control mechanism 40 can include a housing 41, a battery 42 and a control device 43. The housing 41 can be fixedly installed on the side of the frame 10 away from the ground, and the housing 41 is hollow. The battery 42 is accommodated in the housing 41 and is fixedly installed with the housing 41. The battery 42 can be electrically connected with the moving driving member 21 and the traction driving member 352. The control device 43 can be accommodated in the housing 41. The control device 43 is in communication connection with the battery 42, the moving driving member 21 and the traction driving member 352. The control device 43 is used to trigger the moving driving member 21 to work in response to the supply of electric energy, so that the plant trimming device 100 can automatically travel. The control device 43 is also used to trigger the traction driving member 352 to work in response to the supply of electric energy, so that the rolling cutter 351 rotates to realize the traction of the plant by the rolling cutter 351 and the cutting of the plant by the cutting tool 34.

[0177] It can be understood that the battery 42 can supply power to the mechanisms in the plant trimming device 100 that need to move, and the plant trimming device 100 is an electric device. In this way, the environmental pollution and noise generated by the plant trimming device 100 when powered by fuel can be reduced.

[0178] In other embodiments, the power supply mechanism other than the battery 42 can be used to supply power to the control device 43, the movement driving member 21 and the traction driving member 352 in the plant trimming device 100. For example, the plant trimming device 100 can generate power through a solar power generation device (not shown), a wind power generation device (not shown) or other power generation devices, and output the power to the control device 43, the movement driving member 21 and the traction driving member 352. For another example, the plant trimming device 100 can obtain power from a municipal power grid, and output the power to the control device 43, the movement driving member 21 and the traction driving member 352.

[0179] In the embodiments of the present application, the type of the control device 43 is not specifically limited. For example, the control device 43 can be a general central processing unit (CPU), a microprocessor, an application-specific integrated circuit (ASIC), or one or more integrated circuits for controlling the execution of the above program.

[0180] In the embodiments of the present application, the manner of the communication connection is not specifically limited. For example, the communication connection can be a wired communication connection through a hardware device such as a signal line. For another example, the communication connection can be a wireless communication connection through a wireless communication manner such as a wireless network, 3G, 4G, 5G or Bluetooth.

[0181] It can be understood that the control device 43 can control the mechanisms requiring movement in the plant trimming device 100 according to a preset program, thereby improving the convenience of the operator in controlling the plant trimming device 100.

[0182] For example, the control device 43 controls the movement driving member 21 to work, thereby controlling the rotation direction and speed of the traveling wheel 23. In this way, the operator can control the plant trimming device 100 to move forward or backward, and adjust the moving speed of the plant trimming device 100.

[0183] For example, the control device 43 controls the traction driving member 352 to work, thereby controlling the rotation direction of the cutter 351. In this way, the operator can control the cutter 351 to rotate reversely through the control device 43 when sharpening the cutter head 355 of the cutter 351, and sharpen the cutter head 355 through a whetstone or the like.

[0184] Please refer to Figure 1 and Figure 13In some embodiments, the handrail mechanism 60 can include a handrail handle 61 and an interactive device 62. The handrail handle 61 is fixedly connected to the end of the handrail arm mechanism 50 away from the frame 10. The interactive device 62 is rotatably connected to the handrail handle 61 through a damping connector 63. The interactive device 62 is electrically connected to the battery 42, and the battery 42 can supply power to the interactive device 62. The interactive device 62 is communicatively connected to the control device 43. The worker can operate the interactive device 62 according to the working state that the plant trimming device 100 needs to achieve. The interactive device 62 can output a trigger signal to the control device 43 in response to the operation of the user. The control device 43 can control the movement driving member 21 and / or the traction driving member 352 to work, so that the running wheel 23 rotates in a direction and at a speed corresponding to the trigger signal, and the milling cutter 351 rotates in a direction and at a speed corresponding to the trigger signal.

[0185] It can be understood that the interactive device 62 can be an electronic device with human-computer interaction function and communication function. In the embodiments of the present application, the type of the interactive device 62 is not specifically limited. For example, the interactive device 62 can be, but is not limited to, a touch panel.

[0186] It can be understood that the damping connector 63 can be a rotary connector with damping. In the embodiments of the present application, the type of the damping connector 63 is not specifically limited. For example, the damping connector 63 can be a hinge with damping.

[0187] It can be understood that the worker manually rotates the interactive device 62 to make the panel of the interactive device 62 face a direction specified by the worker. The damping in the damping connector 63 can make the interactive device 62 maintain the state that the panel faces the specified direction. In this way, the convenience of the worker adjusting the orientation of the panel of the interactive device 62 can be improved, so that the worker can adjust the orientation of the panel of the interactive device 62 according to the worker's body shape, the intensity of sunlight, the angle of sunlight, and the like, and the convenience of the worker observing and operating the interactive device 62 can be improved.

[0188] In some embodiments, the worker can realize the power-on and power-off of the plant trimming device 100 by operating the interactive device 62.

[0189] In some embodiments, the handrail mechanism 60 further comprises a rotating handle 64. The rotating handle 64 is rotatably connected with the handrail 61. A stroke switch (not shown) can be arranged between the rotating handle 64 and the handrail 61, and the stroke switch is electrically connected with the control device 43. The rotating handle 64 can be manually adjusted by the operator to rotate the rotating handle 64. When the rotating handle 64 is moved away from one end of the rotating handle 64 which is connected with the handrail 61 and approaches the handrail 61, the stroke switch is triggered and outputs a trigger signal to the control device 43, and the control device 43 can control the plant trimming device 100 to be powered on or powered off according to the trigger signal.

[0190] Please refer to Figure 14 and Figure 15 In some embodiments, the second adjusting seat 11 is arranged on the frame 10 in a direction away from the ground. The second adjusting seat 11 is arranged on the second side of the frame 10. The handrail arm mechanism 50 is rotatably connected with the second adjusting seat 11 to adjust the inclination angle of the handrail arm mechanism 50.

[0191] The second adjusting seat 11 is provided with a second space 12. The first clamping member 90 is arranged in the receiving space. The first clamping member 90 is disc-shaped, and the first clamping member 90 is fixedly connected with at least one inner wall of the second space 12. A plurality of clamping grooves 91 are arranged on the peripheral wall of the first clamping member 90 and are spaced apart on the first clamping member 90.

[0192] The handrail arm mechanism 50 can comprise a second connecting seat 51, a handrail arm 52, a second clamping member 53 and a second elastic member 54. The second connecting seat 51 is ring-shaped, and a through groove 511 is formed in the second connecting seat 51. The second connecting seat 51 is arranged in the second space 12, the through groove 511 is in communication with the second space 12, and the first clamping member 90 is arranged in the through groove 511. The handrail arm 52 is fixedly connected with the peripheral wall of the second connecting seat 51. The handrail arm 52 is long and thin. A second sliding groove 521 is arranged in the handrail arm 52 and is in communication with the through groove 511. The second clamping member 53 is arranged in the second sliding groove 521 and is slidably connected with the second sliding groove 521 along the length direction of the handrail arm 52. A plurality of clamping teeth 531 are fixedly arranged on one end of the second clamping member 53 which faces the first clamping member 90, and the plurality of clamping teeth 531 are used for being inserted into the plurality of clamping grooves 91 to realize the clamping of the first clamping member 90 and the second clamping member 53. The second elastic member 54 is connected with the second clamping member 53 and the inner wall of the second sliding groove 521. The second elastic member 54 is used for being elastically deformed under the extrusion of other objects in the second clamping member 53 and the second sliding groove 521, and the elastic force generated by the elastic deformation is used for driving the second clamping member 53 to move towards the first clamping member 90 to realize the clamping of the first clamping member 90 and the second clamping member 53.

[0193] It can be understood that when the first engaging member 90 is engaged with the second engaging member 53, the rotation of the armrest arm 52 relative to the second adjusting seat 11 is limited, thereby limiting the inclination angle of the armrest arm 52.

[0194] Exemplarily, the second sliding groove 521 is fixedly installed with a baffle 522 on the inner wall thereof, and the second elastic member 54 is located between the baffle 522 and the second engaging member 53. The baffle 522 is used to cooperate with the second engaging member 53 to extrude the second elastic member 54.

[0195] In the embodiments of the present application, the type of the second elastic member 54 is not specifically limited. For example, the second elastic member 54 can be, but is not limited to, a spring.

[0196] It can be understood that the inner wall of the through groove 511 can abut against the portion of the circumferential wall of the first engaging member 90 on which the clamping groove 91 is not formed, and the inner wall of the through groove 511 can be in circumferential sliding fit with the circumferential wall of the first engaging member 90, that is, the portion of the first engaging member 90 on which the clamping groove 91 is not formed is in rotational fit with the inner wall of the through groove 511. In this way, the relative rotation connection between the second connecting seat 51 and the second adjusting seat 11 can be achieved.

[0197] In some embodiments, the second engaging member 53 can include a first connecting block 532, a third connecting rod 533 and a second connecting block 534.

When the staff needs to store or transport the plant trimming device 100, the armrest arm 52 can be rotated towards the rack 10, so that the armrest arm 52 is close to the rack 10, and the space occupied by the plant trimming device 100 is reduced.

[0203] Please refer to Figure 16 In some embodiments, the shell 41 can be provided with a notch 411, and the notch 411 can accommodate the rotated armrest arm 52. In this way, when the staff needs to store or transport the plant trimming device 100, the armrest arm 52 can be rotated towards the rack 10 to the notch 411, and the shell 41 provided with the notch 411 can strengthen the protection of the armrest wall when the plant trimming device 100 is stored or transported, and reduce the knocking of the armrest arm 52 by external objects.

[0204] It can be understood that the plant trimming device 100 provided by the embodiments of the present application can reduce the influence of the change of the height of the moving mechanism 20 on the positions of the second connecting frame 32, the cutting tool 34 and the rolling cutter 351 by the relative rotation of the second connecting frame 32 and the first connecting frame 31 and the relative rotation of the first connecting frame 31 and the rack 10, reduce the probability that the supporting assembly 33 of the cutting mechanism 30 cannot keep in close contact with the ground when the ground in the working area of the plant trimming device 100 is uneven, and reduce the probability that the distance between the cutting tool 34 and the traction assembly 35 and the ground changes. In this way, the consistency and flatness of the height of the trimmed plants can be improved, and the plant trimming effect can be improved.

[0205] The plant trimming device 100 provided by the embodiments of the present application limits the rotation of the handrail arm 52 by the clamping of the first clamping part 90 and the second clamping part 53, so that the worker needs to clasp the first clamping part 90 and the second clamping part 53 by the second adjusting part 55 and rotate the handrail arm 52 to adjust the inclination angle of the handrail arm 52. When the worker transports or stores the plant trimming device 100, the worker can conveniently rotate the handrail arm 52 to reduce the space occupied by the plant trimming device 100.

[0206] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the above embodiments of the present application should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
