Description

Technical Field

[0001] This invention relates to the field of greening and landscaping pruning technology, and more specifically to a greening and landscaping device for environmental art design. Background Technology

[0002] Roadside green belts are strips of green space used to separate motor vehicle lanes from non-motor vehicle lanes. They are usually planted in long flower beds. Planting trees in these green belts can also change the spatial scale of the road, giving the road space a good width-to-height ratio. They can beautify and decorate the city, purify the environment, trap dust, reduce noise, absorb harmful gases, release oxygen, eliminate visual fatigue, and reduce traffic accidents.

[0003] After planting, green belts will gradually become messy and disorderly over time, which will not only affect the aesthetics, but the outward-growing green plants may also pose some safety hazards. Therefore, green belts need to be maintained and pruned regularly to maintain their shape and health, promote new growth, and maintain a neat appearance.

[0004] During the pruning of green belts, the traditional pruning method is for workers to use handheld pruning machines. However, handheld pruning machines use gasoline engines as power sources, and the noise, vibration, and exhaust fumes generated by the machines affect the health of the pruning workers. In addition, handheld pruning machines are relatively heavy, making manual pruning slow, inefficient, and unsuitable for large-scale greening maintenance operations.

[0005] Therefore, pruning devices that mount pruning devices on robotic arms or carriers have emerged. For example, patent document CN217336552U discloses a pruning device mounted on a carrier, which uses a robotic arm and a carrier to adjust and control the posture and position of the pruning device. The carrier moves along the extension direction of the green belt, thereby driving the pruning device to perform pruning, thus achieving a more efficient pruning operation.

[0006] However, in actual use, the above-mentioned pruning method only has one pruning mechanism. Since the green belt needs to be pruned on the top and both sides, one side of the green belt can only be pruned first, and then the other two sides can be pruned in turn. A green belt needs to be pruned back and forth three times to complete the pruning work. Although some pruning devices have two pruning mechanisms in the horizontal and vertical directions (such as the patent document with publication number CN206602881U), which can reduce the number of pruning operations, it is still necessary to repeat the pruning operation on the unpruned side. Therefore, there is still a situation of low efficiency.

[0007] Furthermore, the width of the existing pruning mechanism cannot match the height and width of the green belt, resulting in a limited coverage area. When dealing with green belts of different heights and widths, a robotic arm is required to move the pruning device along the height and width of the green belt. This requires workers to perform cumbersome operations on the robotic arm, reducing work efficiency. Moreover, the vehicle needs to occupy the driving lane when moving on both sides of the green belt, which will cause traffic congestion. Therefore, the existing pruning mechanism is cumbersome to operate and inconvenient to use.

[0008] In addition, the environments in which green belts are laid are diverse. Some green belts have pillar-shaped obstacles such as streetlights, trees, and billboards in the middle. The existing pruning mechanism cannot automatically avoid the obstacles during the pruning process. It is necessary to manually control the pruning mechanism to bypass the obstacles and continue pruning. Therefore, most of the green plants around the obstacles cannot be pruned.

[0009] In summary, the present invention provides a greening and decoration device for environmental art design to solve the above-mentioned problems. Summary of the Invention

[0010] In view of the above situation and to overcome the defects of the prior art, the present invention provides a greening and decoration device for environmental art design to solve the problems mentioned in the background art.

[0011] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0012] An environmental art design and landscaping device includes two symmetrically positioned mobile carts. Each cart has a lifting base on its top. A side trimming box is slidably mounted on the top of each lifting base. A lifting trimming box is slidably mounted on the rear side of each side trimming box. A horizontal trimming box extending horizontally towards the middle of the two lifting bases is fixedly mounted on the top of each lifting trimming box, with a gap between the two horizontal trimming boxes. An obstacle avoidance trimming box is slidably mounted on the front side of each horizontal trimming box, with the ends of the two obstacle avoidance trimming boxes abutting each other. Each side trimming box, lifting trimming box, horizontal trimming box, and obstacle avoidance trimming box has an opening on its side facing the middle of the two lifting bases, and a chainsaw is installed inside. Obstacle avoidance components are installed on the front sides of the two obstacle avoidance trimming boxes and the rear sides of the two horizontal trimming boxes.

[0019] Preferably, the obstacle avoidance assembly includes a front obstacle avoidance compression plate, a front obstacle avoidance ramp, a rear obstacle avoidance compression plate, and a rear obstacle avoidance ramp.

[0020] Both of the obstacle avoidance trimming boxes are fixedly installed with front obstacle avoidance extrusion plates. The two front obstacle avoidance extrusion plates are close to each other at one end under the elastic force of the elastic adjustment component, and each is provided with a front obstacle avoidance slope facing forward.

[0021] A rear obstacle avoidance compression plate is slidably installed on the slide rail on the rear side of each horizontal trimming box. The two rear obstacle avoidance compression plates are brought into contact with each other by the elastic force of the elastic adjustment component, and each is provided with a rear obstacle avoidance slope facing forward.

[0022] Preferably, a connecting slot is provided on the abutting surface of one of the front obstacle avoidance extrusion plates and the abutting surface of one of the rear obstacle avoidance extrusion plates. A wedge-shaped plug is fixedly installed on the abutting surface of the other front obstacle avoidance extrusion plate and the rear obstacle avoidance extrusion plate. A limiting semi-circular groove is provided on the upper and lower inner walls of each connecting slot. A limiting hole is provided on the upper and lower sides of each wedge-shaped plug.

[0026] Each of the horizontal trimming boxes has a hollow spring plate adjusting box fixedly installed on its top. Each spring plate adjusting box has a spring plate adjusting block that slides left and right inside it. Spring plate adjusting slots pass through the front and rear sides of the spring plate adjusting box and its interior. Spring plate adjusting rods that pass through the two spring plate adjusting slots are fixedly installed on the front and rear sides of the spring plate adjusting block. Each spring plate adjusting rod is fixedly connected to the top of the spring plate on the corresponding side. Each spring plate adjusting box has a spring plate screw that is threaded to the spring plate adjusting block and is rotatably installed inside it. Each spring plate screw is connected to a spring plate motor.

[0027] The beneficial effects of this invention are as follows:

[0028] 1. For flower beds of different heights, the height of the lifting base can be adjusted to match the height of the top surface of the flower bed. When the height of the green belt is higher than the side trimming box, the lifting trimming box can be moved upward to make it level with the top surface of the green belt. Therefore, the side trimming box and the lifting trimming box can cover the entire height of the side of the green belt, thus making it suitable for trimming green belts of different heights. After adjusting the position of the side trimming box and the lifting trimming box outward or inward, it can be determined whether the side of the green plant exceeds the outer surface of the flower bed.

[0029] 2. When the moving trolley and lifting base are in contact with the outer side of the flower bed, the two horizontal trimming boxes are positioned horizontally on both sides of the top surface of the green belt for trimming. The two obstacle avoidance trimming boxes are in contact with each other at their closest ends, thus compensating for the areas that cannot be trimmed due to the distance between the two horizontal trimming boxes. When the distance between the two horizontal trimming boxes changes, simply move the two obstacle avoidance trimming boxes towards the middle so that they are in contact again. Therefore, when trimming green belts of different widths, the cooperation between the two horizontal trimming boxes and the two obstacle avoidance trimming boxes can achieve trimming across the top surface of the green belt.

[0030] 3. Based on the coordination between the side trimming box, the lifting trimming box, the horizontal trimming box and the obstacle avoidance trimming box, the trimming of a green belt can be completed by moving from one end of the green belt to the other only once, driven by the moving vehicle. Compared with the existing single or two trimming mechanisms, it saves the number of trimmings and can improve trimming efficiency.

[0031] 4. When encountering upright obstacles such as lampposts or trees in the green belt, the obstacle avoidance components installed on the front of the two obstacle avoidance trimmers will first contact the obstacle (see attached diagram). Figure 4 Then, the obstacle avoidance component can be pushed to the left and right sides, thereby causing the two obstacle avoidance trimmers to move to the left and right sides respectively, allowing the obstacle to pass between the two obstacle avoidance trimmers (see attached). Figure 5 Based on the positioning of the positioning wheels, when the obstacle squeezes the obstacle avoidance component and the two obstacle avoidance trimming boxes to both sides, the moving trolley and the lifting base will not separate from the outer side of the flower bed. At this time, the two obstacle avoidance trimming boxes can trim the green plants on the left and right sides near the obstacle.

[0032] 5. When the obstacle moves between the two horizontal trimming boxes, the two obstacle avoidance trimming boxes and the obstacle avoidance components can be reset to the center and abutted under the elastic force of the elastic adjustment components. The moving trolley continues to move, so that the obstacle abuts against the obstacle avoidance components located on the rear side of the two horizontal trimming boxes and pushes them to the left and right to allow the obstacle to pass. The above operation achieves the effect of avoiding obstacles during trimming.

[0033] 6. Each set of obstacle avoidance components (two front obstacle avoidance compression plates and two rear obstacle avoidance compression plates) can be connected by a plug-in joint. That is, when one set of obstacle avoidance components separates to the left or right, the other set of obstacle avoidance components is in a plug-in joint state. This avoids the situation where the two moving trolleys are misaligned during movement, making it impossible to plug in the separated obstacle avoidance components when they are reset. In addition, when trimming green belts without obstacles, the two front obstacle avoidance compression plates and the two rear obstacle avoidance compression plates can be fixed together with fixing bolts.

[0049] The following will refer to the appendix. Figures 1-14 The description provides a detailed description of various embodiments of the present invention.

[0050] A greening and decorative equipment for environmental art design, as shown in the attached document. Figure 1-14 As shown, the system includes two mobile carts 1 symmetrically positioned to the left and right of the center of the green belt. Each cart 1 is equipped with a drive mechanism (such as wheels and a drive motor) and a power source (such as a battery). They can be synchronously controlled via a remote control, allowing each cart to move along the outer edge of the flower bed within the green belt, thereby driving a subsequent pruning mechanism. Each cart 1 has a lifting base 2 mounted on its top. During use, the cart 1 and lifting base 2 are brought into contact with the outer surface of the flower bed and positioned using positioning wheels 18, ensuring that the cart 1 and lifting base 2 do not separate from the outer surface of the flower bed during movement (see attached diagram). Figure 2(The area below the positioning rod 17 in the figure is a flower bed, and the dotted line represents green plants.) The mobile trolley 1 and the lifting base 2 occupy a small space and will not affect traffic. For flower beds of different heights, the height of the lifting base 2 can be adjusted so that the top surface of the lifting base 2 matches the top surface of the flower bed. The top of each of the two lifting bases 2 is equipped with a side trimming box 3 that slides left and right. The rear side of each side trimming box 3 is equipped with a lifting trimming box 4 that slides up and down. When the height of the green belt is higher than the side trimming box 3, the lifting trimming box 4 can be moved upward to make it level with the top surface of the green belt. Therefore, the side trimming box 3 and the lifting trimming box 4 can cover the entire height of the side of the green belt, thus making it suitable for trimming green belts of different heights.

[0051] Once the moving trolley 1 and the lifting base 2 are in contact with the outer side of the flower bed, the positions of the side trimming box 3, the lifting trimming box 4, and the side of the green belt can be adjusted to determine the trimming length of the green belt side, as shown in the attached diagram. Figure 2 As shown, the working surfaces of the side trimming box 3 and the lifting trimming box 4 are flush with the side of the lifting base 2, that is, flush with the outer side of the flower bed. Therefore, the side of the trimmed green plant is also flush with the outer side of the flower bed. After adjusting the position of the side trimming box 3 and the lifting trimming box 4 outward or inward, it can be determined whether the side of the green plant exceeds the outer side of the flower bed.

[0052] Each of the aforementioned lifting trimming boxes 4 has a horizontal trimming box 5 fixedly installed on its top, extending horizontally towards the middle of the two lifting bases 2, with a gap between the two horizontal trimming boxes 5. When the moving trolley 1 and the lifting base 2 abut against the outer side of the flower bed, the two horizontal trimming boxes 5 are positioned horizontally on both sides of the top surface of the green belt for trimming. When used for green belts of different widths, the gap between the two moving trolleys 1 and the lifting base 2 changes, and the gap between the two horizontal trimming boxes 5 also changes accordingly. Each of the aforementioned horizontal trimming boxes 5 has an obstacle avoidance trimming box 6 slidably installed on its front side, with two obstacle avoidance trimming boxes 6 slidably installed on its front side. The obstacle avoidance trimming boxes 6 abut against each other at their closest ends, thereby compensating for the areas that cannot be trimmed due to the distance between the two horizontal trimming boxes 5. When the distance between the two horizontal trimming boxes 5 changes, the two obstacle avoidance trimming boxes 6 can simply be moved towards the center to abut against each other. Therefore, when trimming green belts of different widths, the cooperation between the two horizontal trimming boxes 5 and the two obstacle avoidance trimming boxes 6 can achieve trimming across the top surface of the green belt, eliminating the need for cumbersome operation of the robotic arm required by existing trimming devices to ensure that the trimming mechanism covers the entire side of the green belt.

[0053] Each of the side trimming boxes 3, lifting trimming boxes 4, horizontal trimming boxes 5, and obstacle avoidance trimming boxes 6 has an opening on the side facing the middle of the two lifting bases 2, and a trimming chainsaw 7 is installed inside. The trimming chainsaw 7 can be an existing chainsaw. The trimming chainsaw 7 in the side trimming boxes 3 and lifting trimming boxes 4 located on both sides of the green belt trims the two sides of the green belt, and the trimming chainsaw 7 in the two horizontal trimming boxes 5 and the two obstacle avoidance trimming boxes 6 trims the top surface of the green belt. Driven by the moving trolley 1, the trimming work of a green belt can be completed by moving from one end of the green belt to the other end once. Compared with the existing single or two trimming mechanisms, it saves the number of trimmings and can improve the trimming efficiency.

[0054] Obstacle avoidance components 8 are installed on the front sides of the two obstacle avoidance trimming boxes 6 and the rear sides of the two horizontal trimming boxes 5. Each horizontal trimming box 5 is equipped with an elastic adjustment component 9 connected to the obstacle avoidance component 8. When trimming along the green belt, if it encounters upright obstacles such as lampposts or trees, the obstacle avoidance components 8 installed on the front sides of the two obstacle avoidance trimming boxes 6 will first contact the obstacle (see attached diagram). Figure 4 (The circular dotted lines in the diagram represent obstacles). The obstacles then push the obstacle avoidance component 8 to the left and right, causing the two obstacle avoidance trimming boxes 6 to move to the left and right respectively, allowing the obstacle to pass between the two obstacle avoidance trimming boxes 6 (see attached diagram). Figure 5 (The circular dotted lines in the figure represent obstacles). Based on the positioning of the positioning wheel 18, when the obstacle squeezes the obstacle avoidance component 8 and the two obstacle avoidance trimming boxes 6 to both sides, the moving trolley 1 and the lifting base 2 will not separate from the outer side of the flower bed. At this time, the two obstacle avoidance trimming boxes 6 can trim the green plants close to the left and right sides of the obstacle. The obstacle avoidance components 8 of each group are connected by a plug-in cooperation method. That is, when one group of obstacle avoidance components 8 separates to the left and right sides, the other group of obstacle avoidance components 8 is in a plug-in cooperation state, which avoids the situation where the two moving trolleys 1 are misaligned during the movement, so that the separated obstacle avoidance components 8 cannot be plugged in when they are reset.

[0055] When the obstacle moves between the two horizontal trimming boxes 5, the two obstacle avoidance trimming boxes 6 and the obstacle avoidance component 8 can be reset to the center and abutted under the elastic force of the elastic adjustment component 9. The moving trolley 1 continues to move, so that the obstacle abuts against the obstacle avoidance component 8 located on the rear side of the two horizontal trimming boxes 5 and pushes it to the left and right to allow the obstacle to pass. The above operation achieves the effect of avoiding obstacles during the trimming process.

[0056] As attached Figure 7As shown, each of the lifting bases 2 has two lifting holes 10 and one screw hole 11 on its bottom surface. A lifting rod 12 that slides with the lifting holes 10 is installed on the top surface of the mobile trolley 1. The sliding engagement between the lifting holes 10 and the lifting rod 12 allows the lifting base 2 and the mobile trolley 1 to move only vertically relative to each other. A motor slot is provided at the bottom of the mobile trolley 1, and a base lifting motor 13 is installed in the motor slot. The base lifting motor 13 is electrically connected to a battery and can be remotely controlled by a remote control. The rotating shaft of the base lifting motor 13 is connected to a base lifting screw 14 that is threaded with the screw hole 11. When it is necessary to adjust the height of the lifting base 2, the base lifting motor 13 can be started to drive the base lifting screw 14 to rotate, so that it is threaded with the screw hole 11, thereby driving the lifting base 2 to move up and down to achieve its height adjustment.

[0057] As attached Figure 8 , Figure 9 As shown, each of the two lifting bases 2 has a wheel groove on its opposite side, and a rotating wheel 15 is rotatably installed in each wheel groove. The lifting base 2 abuts against the outer side of the flower bed through the rotating wheel 15 to reduce friction. Hollow positioning cylinders 16 are fixedly installed at both ends of the top surface of each lifting base 2. Each positioning cylinder 16 has an opening at one end facing the other lifting base 2, and a positioning rod 17 is slidably installed inside. A handle is installed on the top surface of the positioning rod 17. A positioning wheel 18 is rotatably installed on the bottom surface of the end of the positioning rod 17 away from the positioning cylinder 16. A positioning tension spring 19 connects the positioning rod 17 and the interior of the positioning cylinder 16. (See attached diagram.) Figure 9 As shown, during the process of bringing the lifting base 2 into contact with the outer side of the flower bed, the handle can be pulled to pull the positioning rod 17 out from the inside of the positioning cylinder 16 to the outside, and the positioning wheel 18 abuts against the inner side of the flower bed. The positioning spring 19 is then stretched and stored. Under the elastic force of the positioning spring 19, the lifting base 2 will not separate from the outer side of the flower bed during the movement and when it is subjected to the squeezing force of obstacles to the left and right sides. The different lengths of the positioning rod 17 can be used for flower beds of different widths.

[0058] As attached Figure 10As shown, the top of the lifting base 2 is provided with a trimming adjustment groove 20. The bottom of the side trimming box 3 is fixedly installed with a trimming adjustment screw block 21 located in the trimming adjustment groove 20. A trimming adjustment screw 22 that is threadedly engaged with the trimming adjustment screw block 21 is rotatably installed in the trimming adjustment groove 20. The trimming adjustment screw 22 is connected to a trimming adjustment motor 23, which is electrically connected to a battery and can be remotely controlled by a remote control. When it is started, it drives the trimming adjustment screw 22 to rotate, and the trimming adjustment screw block 21 that is threadedly engaged with it can move in the trimming adjustment groove 20, thereby driving the side trimming box 3 to move left and right on the top of the lifting base 2, thereby changing the trimming length of the side of the green plant. A groove protection plate 24 is connected between the trimming adjustment screw block 21 and the trimming adjustment groove 20. When the trimming adjustment screw block 21 moves, it can drive the groove protection plate 24 to extend and retract, which can protect the trimming adjustment groove 20 and prevent the cut green plant from falling into it.

[0059] As attached Figure 1 , Figure 3 , Figure 7 As shown, a lifting drive box 25 is fixedly installed on each of the two opposing sides of the side trimming box 3. A lifting screw 26 is rotatably installed inside the lifting drive box 25. Each lifting trimming box 4 is fixedly installed with a lifting screw block 27 located inside the lifting drive box 25 and threadedly engaged with the lifting screw 26. The lifting screw 26 is connected to a lifting motor 28, which is electrically connected to a battery and can be remotely controlled by a remote controller. When it is started, it drives the lifting screw 26 to rotate, which drives the threaded lifting screw block 27 to move up and down inside the lifting drive box 25, thereby moving the lifting trimming box 4 up and down to adjust its height.

[0060] As attached Figure 1 , Figure 8 As shown, each of the side trimming box 3, lifting trimming box 4, horizontal trimming box 5, and obstacle-avoiding trimming box 6 has trimming slots 29 on both its front and rear sides. During moving trimming, the green plants can enter the interior of multiple trimming boxes through the trimming slots 29, where they can be trimmed by the trimming chainsaw 7. Each trimming slot 29 is equipped with multiple protective plates 30 made of rubber to prevent green plants from flying everywhere during trimming. Figure 3 As shown, the bottom of the outer side of the side trimming box 3 and the lifting trimming box 4 are provided with through grooves to discharge the branches and leaves inside after trimming. Each of the trimming chainsaws 7 is connected to a power source 31. The power source 31 can be an electric motor or, as in the prior art, a gasoline engine. The power source 31 can drive the trimming chainsaw 7 to rotate. The lifting trimming box 4 and the horizontal trimming box 5 are fixedly connected by a triangular rib plate 32, and the triangular rib plate 32 is fixed to both of them by bolts.

[0061] As attached Figure 14 As shown, each of the horizontal trimming boxes 5 is fixedly mounted with a slide rail 33 on its front and rear sides. The obstacle avoidance trimming box 6 is slidably connected to the slide rail 33, so that the obstacle avoidance trimming box 6 can slide left and right on the side of the horizontal trimming box 5.

[0062] As attached Figures 4-7 , Figures 11-14 As shown, the obstacle avoidance assembly 8 includes a front obstacle avoidance compression plate 34, a front obstacle avoidance ramp 35, a rear obstacle avoidance compression plate 36, and a rear obstacle avoidance ramp 37.

[0063] Both of the obstacle avoidance trimming boxes 6 are fixedly installed with front obstacle avoidance extrusion plates 34. The two front obstacle avoidance extrusion plates 34 are close to each other at one end under the elastic force of the elastic adjustment component 9, and each is provided with a front obstacle avoidance slope 35 facing forward.

[0064] Each horizontal trimming box 5 has a rear obstacle avoidance squeezing plate 36 slidably installed on the slide rail 33 on the rear side. The two rear obstacle avoidance squeezing plates 36 are close to each other at one end under the elastic force of the elastic adjustment component 9, and are respectively provided with a rear obstacle avoidance slope 37 facing forward.

[0065] As attached Figure 4 As shown, during the forward trimming process, the columnar obstacle will come into contact with the two forward obstacle avoidance ramps 35, as shown in the attached diagram. Figure 5 As shown, after the two front obstacle avoidance ramps 35 come into contact with the obstacle, they are pushed to the left and right by the obstacle, thereby causing the two obstacle avoidance trimming boxes 6 to separate to the left and right. The obstacle can then pass between the two obstacle avoidance trimming boxes 6. At this time, the two rear obstacle avoidance compression plates 36 are still in contact with each other to ensure that the front and rear positions of the two horizontal trimming boxes 5 are consistent. After the obstacle reaches between the two horizontal trimming boxes 5, the two obstacle avoidance trimming boxes 6 and the two front obstacle avoidance ramps 35 are closed and reset to the center under the elastic force of the elastic adjustment component 9.

[0066] Then the obstacle can come into contact with the two rear obstacle avoidance ramps 37 and push the two rear obstacle avoidance compression plates 36 to the left and right sides, so that the obstacle can pass through. Finally, the two rear obstacle avoidance compression plates 36 are closed and reset in the middle under the elastic force of the elastic adjustment component 9, thereby realizing the automatic obstacle avoidance operation during the trimming process.

[0067] As attached Figure 13As shown, a connecting slot 38 is provided on the abutting surface of one of the front obstacle avoidance extrusion plates 34 and the abutting surface of one of the rear obstacle avoidance extrusion plates 36. A wedge-shaped plug 39 is fixedly installed on the abutting surface of the other front obstacle avoidance extrusion plate 34 and the rear obstacle avoidance extrusion plate 36. The wedge-shaped plug 39 has a forward-facing inclined surface. By inserting the wedge-shaped plug 39 into the connecting slot 38, when the two front obstacle avoidance extrusion plates 34 or the two rear obstacle avoidance extrusion plates 36 are separated to the sides, the other set of unseparated wedge-shaped plugs 39 are in a plugged-in state with the connecting slot 38. This ensures that the front and rear positions of the two mobile trolleys 1, the lifting base 2 and the two horizontal trimming boxes 5 are consistent, so that the separated wedge-shaped plugs 39 and the connecting slot 38 can be smoothly closed and plugged in.

[0068] Each of the connecting slots 38 has a limiting semi-circular groove 40 on its upper and lower inner walls, and each of the wedge-shaped inserts 39 has a limiting hole 41 on its upper and lower sides. Each of the limiting holes 41 has a limiting spring 42 fixedly installed inside it, and each of the limiting holes 41 has a limiting ball 43 embedded inside its opening that abuts against the limiting spring 42.

[0069] When the soil inside the flower bed is level with the top of the flower bed, the positioning wheel 18 cannot be locked inside the flower bed to provide fixation and positioning for the moving trolley 1 and the lifting base 2. At this time, the positioning rod 17 does not need to be pulled outward, and the positioning wheel 18, like the rotating wheel 15, can abut against the outer side of the flower bed. When the two front obstacle avoidance compression plates 34 are squeezed by obstacles, they may simultaneously push the two front obstacle avoidance compression plates 34 and the two rear obstacle avoidance compression plates 36 to the left and right sides, causing all the equipment located on both sides of the green belt to move outward and unable to automatically close and reset in the middle. Therefore, while the connecting slot 38 and the wedge-shaped plug 39 are engaged, the engagement between the limiting ball 43 and the limiting hole 41 provides the left and right limiting force for the connecting slot 38 and the wedge-shaped plug 39. When the two front obstacle avoidance compression plates 34 are squeezed by obstacles, they separate to the left and right, while the two rear obstacle avoidance compression plates 36 remain in abutment under the limiting action between the limiting ball 43 and the limiting hole 41.

[0070] Bolt fixing seats 44 are fixedly installed on the top of the two front obstacle avoidance squeezing plates 34 that abut against each other, and on the top of the two rear obstacle avoidance squeezing plates 36 that abut against each other. A fixing bolt 45 is detachably installed between each pair of abutting bolt fixing seats 44. When there are obstacles in the green belt, obstacle avoidance is not required. At this time, the bolt fixing seats 44 can be connected by turning the fixing bolt 45, thereby connecting the equipment located on both sides of the green belt into a whole equipment, which can then be used to trim the green belt.

[0071] As attached Figure 14As shown, the elastic adjustment component 9 includes a spring plate 46, an obstacle avoidance spring rod 47, an obstacle avoidance reset spring 48, a spring plate adjustment box 49, a spring plate adjustment block 50, a spring plate adjustment groove 51, a spring plate adjustment rod 52, a spring plate lead screw 53, and a spring plate motor 54.

[0072] Each of the slide rails 33 is slidably mounted with a spring plate 46, and each of the obstacle avoidance trimming boxes 6 and each of the rear obstacle avoidance compression plates 36 is fixedly connected with an obstacle avoidance spring rod 47. Each obstacle avoidance spring rod 47 passes through the corresponding spring plate 46, and an obstacle avoidance return spring 48 is sleeved on the outside of each obstacle avoidance spring rod 47 and abuts against the spring plate 46. When the distance between the two horizontal trimming boxes 5 changes, the position of the sliding spring plate 46 can be adjusted to allow the two obstacle avoidance trimming boxes 6 to... After the two rear obstacle avoidance compression plates 36 re-abut and the spring plate 46 is positioned, when the obstacle squeezes the two front obstacle avoidance compression plates 34 or the two rear obstacle avoidance compression plates 36 to separate to the left and right, the two obstacle avoidance trimming boxes 6 and the two rear obstacle avoidance compression plates 36 drive the obstacle avoidance spring rod 47 to move toward the spring plate 46 and compress the obstacle avoidance reset spring 48. After the obstacle passes, the two obstacle avoidance trimming boxes 6 and the two rear obstacle avoidance compression plates 36 can close and reset to the abutment state in the middle under the elastic force of the obstacle avoidance reset spring 48.

[0073] Each of the horizontal trimming boxes 5 has a hollow spring plate adjusting box 49 fixedly installed on its top. A spring plate adjusting block 50 is slidably installed inside each spring plate adjusting box 49. Spring plate adjusting slots 51 extend through the front and rear sides of each spring plate adjusting box 49 and its interior. Spring plate adjusting rods 52, passing through two spring plate adjusting slots 51, are fixedly installed on the front and rear sides of each spring plate adjusting block 50. Each spring plate adjusting rod 52 is fixedly connected to the top of the corresponding spring plate 46. Each box 49 contains a spring plate screw 53 that is threadedly engaged with the spring plate adjusting block 50. Each spring plate screw 53 is connected to a spring plate motor 54. The spring plate motor 54 is electrically connected to the battery and can be remotely controlled by a remote controller. When it is started, it can rotate the spring plate screw 53, thereby driving the spring plate adjusting block 50 to move left and right within the spring plate adjusting box 49. The spring plate adjusting block 50 drives the spring plate 46 to move through the spring plate adjusting rods 52 fixed on its front and rear sides, thereby realizing the position adjustment of the spring plate 46.
