Description

Technical Field

[0001] The present invention relates to the technical field of greening decoration pruning, and particularly relates to a greening decoration device for environmental art design. Background Art

[0002] The road median green belt is a strip-shaped greening area used to separate motor vehicle lanes and non-motor vehicle lanes. It is generally planted in a long flower bed. Planting arbor green belts can also change the spatial scale of the road, making the road space have a good aspect ratio. It can beautify and decorate the city, purify the environment, can retain dust, reduce noise, absorb harmful gases, release oxygen, eliminate visual fatigue, reduce traffic accidents, etc.

[0003] After the green belt is planted, it will gradually become disorderly over time, which will not only affect the beauty, but also the outstretched green plants may bring some safety hazards. Therefore, the green belt needs to be regularly maintained and pruned to maintain its shape and health, promote new growth and maintain a tidy appearance.

[0004] During the process of pruning the green belt, the traditional pruning method is that workers use a handheld pruning machine for pruning. The handheld pruning machine uses a gasoline engine as power, and the noise, vibration and exhaust gas generated by the machine operation have an impact on the physical health of the pruning workers. Moreover, the handheld pruning machine is relatively heavy, making the manual pruning method slow and inefficient, and not suitable for large-scale greening maintenance operations.

[0005] Therefore, pruning equipment with a pruning device installed on a robotic arm or a vehicle has been derived. For example, the patent document with the publication number CN217336552U discloses a pruning device installed on a vehicle, which uses a robotic arm and a vehicle to adjust and control the posture and position of the pruning device. The vehicle moves along the extension direction of the green belt, thereby driving the pruning device to perform pruning, so as to achieve a higher efficiency of pruning operation.

[0006] However, when using the pruning method of the above device in actual use, since it is only provided with one pruning mechanism, and the green belt needs to be pruned on the top surface and both side surfaces, it can only prune one side of the green belt first, and then prune the other two sides in turn. A green belt needs to be pruned back and forth three times to complete the pruning work. Although some pruning devices are provided with two pruning mechanisms in the horizontal and vertical directions (such as the patent document with the publication number CN206602881U), although the pruning times can be reduced, it is still necessary to perform sequential pruning operations on the unpruned side again. Therefore, the efficiency is still low.

[0007] Moreover, the width of the existing pruning mechanism cannot match the height and width of the green belt, resulting in a limited coverage range of the pruning mechanism. When facing green belts of different heights and widths, the robotic arm needs to drive the pruning device to move along the height and width directions of the green belt for pruning. This requires workers to perform cumbersome operations on the robotic arm, reducing work efficiency. In addition, when the vehicle moves on both sides of the green belt, it occupies the traffic lane, causing traffic congestion. Therefore, the existing pruning mechanism is cumbersome to operate and inconvenient to use.

[0008] In addition, the environment where the green belt is laid is diverse. There are columnar obstacles such as street lights, trees, and billboards erected in the middle of some green belts. However, the existing pruning mechanism cannot automatically avoid obstacles during pruning and requires manual control to bypass the obstacles before continuing pruning. Therefore, most of the green plants around the obstacles cannot be pruned.

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

Each spring plate lead screw is connected to a spring plate motor.

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

[0028] 1. For flower beds of different heights, the height of the lifting base can be adjusted so that the top surface of the lifting base matches the top surface height of the flower bed. When the height of the green belt is higher than that of the side trimming box, the lifting trimming box can be moved upward to be flush 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 being applicable to the trimming of green belts of different heights. After the positions of the side trimming box and the lifting trimming box are adjusted outward or inward, it can determine whether the sides of the green plants exceed the outer side of the flower bed.

[0029] 2. When the moving trolley and the lifting base are in contact with the outer side of the flower bed, two horizontal trimming boxes are horizontally arranged on both sides of the top surface of the green belt for trimming. The ends of the two obstacle avoidance trimming boxes that are close to each other are in contact, so as to make up for the positions that cannot be trimmed in the gap between the two horizontal trimming boxes. When the gap between the two horizontal trimming boxes changes, only need to 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 cooperation between the side trimming box, the lifting trimming box, the horizontal trimming box and the obstacle avoidance trimming box, driven by the moving trolley, only need to move from one end of the green belt to the other end for trimming once, then the trimming work of a green belt can be completed. Compared with the existing single or two trimming mechanisms, it saves the trimming times and can improve the trimming efficiency.

[0031] 4. If encountering columnar obstacles such as lamp posts and trees erected in the green belt, the obstacle avoidance components installed on the front sides of the two obstacle avoidance trimming boxes first come into contact with the obstacles (refer to the appendix Figure 4 ), then the obstacles can push the obstacle avoidance components to the left and right sides, thereby driving the two obstacle avoidance trimming boxes to move to the left and right sides respectively, so that the obstacles can pass through between the two obstacle avoidance trimming boxes (refer to the appendix Figure 5 ). Based on the positioning of the positioning wheels, when the obstacles squeeze the obstacle avoidance components and the two obstacle avoidance trimming boxes to the two 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 near the left and right sides of the obstacles.

[0032] 5. When the obstacles move between the two horizontal trimming boxes, the two obstacle avoidance trimming boxes and the obstacle avoidance components can reset to the contact state towards the middle under the elastic force of the elastic adjustment components. The moving trolley continues to move, so that the obstacles come into contact with the obstacle avoidance components on the rear sides of the two horizontal trimming boxes and push them to the left and right sides to let the obstacles pass through. Through the above operations, the effect of avoiding obstacles during the trimming process is achieved.

[0033] 6. The obstacle avoidance components in each group (two front obstacle avoidance pressing plates and two rear obstacle avoidance pressing plates) can be connected by means of insertion. That is, when one group of obstacle avoidance components separates to the left and right sides, the obstacle avoidance components of the other group are in an insertion fit state, avoiding the situation that the two mobile carts are misaligned front and back during movement and the separated obstacle avoidance components cannot be inserted when reset. In addition, when trimming the green belt without obstacles, the two front obstacle avoidance pressing plates and the two rear obstacle avoidance pressing plates can be fixed by fixing bolts.

Specific embodiments

[0049] Next, each embodiment of the present invention will be described in detail with reference to the attached Figures 1 - 14 drawings.

[0050] A greening decoration device for environmental art design, as shown in the attached Figures 1 - 14 drawings, includes two mobile trolleys 1 symmetrically arranged left and right with the center of the green belt as the center. Driving mechanisms (such as mobile wheels, driving motors, etc.) and power devices (such as storage batteries, etc.) are installed inside both mobile trolleys 1, and they can be synchronously controlled by a remote control, enabling them to move along the outer sides of the flower beds of the green belt respectively, thereby driving the subsequent trimming mechanisms to perform mobile trimming. Lifting bases 2 are installed on the tops of both mobile trolleys 1. During use, the mobile trolleys 1 and the lifting bases 2 are abutted against the outer sides of the flower beds, and positioning is achieved through the positioning wheels 18, so that the mobile trolleys 1 and the lifting bases 2 will not separate from the outer sides of the flower beds during the movement process (refer to the attached Figure 2, below the positioning rod 17 in the figure is a flower bed, and the dotted line represents green plants), and the space occupied by the mobile trolley 1 and the lifting base 2 is small 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 height of the flower bed. On the top of each of the two lifting bases 2, a side trimming box 3 is slidably installed left and right. On the rear side of each side trimming box 3, a lifting trimming box 4 is slidably installed 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 be flush 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 being suitable for trimming green belts of different heights.

[0051] When the mobile 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 and the lifting trimming box 4 relative to the side of the green belt can be adjusted, so as to determine the trimming length of the side of the green belt. As shown in the appendix 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 plants is also flush with the outer side of the flower bed. After the positions of the side trimming box 3 and the lifting trimming box 4 are adjusted outward or inward, it can be determined whether the side of the green plants extends beyond the outer side of the flower bed.

[0052] On the top of each lifting trimming box 4, a horizontal trimming box 5 extending horizontally towards the middle position between the two lifting bases 2 is fixedly installed, and there is a spacing between the two horizontal trimming boxes 5. When the mobile trolley 1 and the lifting base 2 are in contact with the outer side of the flower bed, the two horizontal trimming boxes 5 are horizontally arranged on both sides of the top surface of the green belt for trimming. When used for green belts of different widths, the spacing between the two mobile trolleys 1 and the lifting bases 2 changes, and then the spacing between the two horizontal trimming boxes 5 also changes accordingly. On the front side of each horizontal trimming box 5, an obstacle avoidance trimming box 6 is slidably installed left and right. The ends of the two obstacle avoidance trimming boxes 6 close to each other are in contact, so as to make up for the positions that cannot be trimmed in the spacing between the two horizontal trimming boxes 5. When the spacing between the two horizontal trimming boxes 5 changes, only need to move the two obstacle avoidance trimming boxes 6 towards the middle to make them in contact. 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, without the need for cumbersome operations on the robotic arm as in existing trimming devices to make the trimming mechanism cover 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 position between the two lifting bases 2, and a trimming chain saw 7 is installed inside. The trimming chain saw 7 can be an existing chain saw. The trimming chain saws 7 in the side trimming boxes 3 and lifting trimming boxes 4 on both sides of the green belt trim the two side surfaces of the green belt, and the trimming chain saws 7 in the two horizontal trimming boxes 5 and the two obstacle avoidance trimming boxes 6 trim the top surface of the green belt. Driven by the moving trolley 1, only by moving from one end of the green belt to the other end once can the trimming work of one green belt be completed. Compared with the existing single or two trimming mechanisms, the trimming times are saved, and the trimming efficiency can be improved.

[0054] Obstacle avoidance components 8 are installed on the front side surfaces of the two obstacle avoidance trimming boxes 6 and on the rear side surfaces of the two horizontal trimming boxes 5. An elastic adjustment component 9 connected to the obstacle avoidance component 8 is installed on the horizontal trimming box 5. When moving along the green belt for trimming, if columnar obstacles such as lamp posts and trees erected in the green belt are encountered, the obstacle avoidance components 8 installed on the front sides of the two obstacle avoidance trimming boxes 6 first abut against the obstacles (refer to the appendix Figure 4 , the circular dotted line in the figure is the obstacle), and then the obstacles can push the obstacle avoidance components 8 to the left and right sides, thereby driving the two obstacle avoidance trimming boxes 6 to move to the left and right sides respectively, so that the obstacles can pass between the two obstacle avoidance trimming boxes 6 (refer to the appendix Figure 5 , the circular dotted line in the figure is the obstacle). Based on the positioning of the positioning wheels 18, when the obstacles squeeze the obstacle avoidance components 8 and the two obstacle avoidance trimming boxes 6 to the two sides, the moving trolley 1 and the lifting base 2 will not separate from the outer side surface of the flower bed. At this time, the two obstacle avoidance trimming boxes 6 can trim the green plants near the left and right sides of the obstacles. The obstacle avoidance components 8 in each group are connected by an insertion fit 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 an insertion fit state, avoiding the situation that the two moving trolleys 1 are misaligned front and back during the movement and the separated obstacle avoidance components 8 cannot be inserted when resetting;

[0055] When the obstacle moves between the two horizontal trimming boxes 5, the two obstacle avoidance trimming boxes 6 and the obstacle avoidance components 8 can reset to the abutting state towards the middle 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 components 8 on the rear side surfaces of the two horizontal trimming boxes 5 and pushes them to the left and right sides to allow the obstacle to pass through. Through the above operations, the effect of avoiding obstacles during trimming is achieved.

[0056] As shown in the appendix Figure 7As shown in the figure, two lifting holes 10 and one screw hole 11 are formed in the bottom surface of each lifting base 2. A lifting rod 12 that is slidably engaged with the lifting holes 10 is installed on the top surface of the mobile trolley 1. The sliding fit between the lifting holes 10 and the lifting rod 12 enables only vertical relative movement between the lifting base 2 and the mobile trolley 1. A motor slot is formed in 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 the battery and can be remotely controlled by a remote controller. The rotating shaft of the base lifting motor 13 is connected to a base lifting lead screw 14 that is threadedly engaged 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 lead screw 14 to rotate, so that it is threadedly driven with the screw hole 11, thereby driving the lifting base 2 to move up and down to realize the adjustment of its height.

[0057] As shown in the attached Figure 8 , Figure 9 figure, wheel grooves are formed on the opposite sides of the two lifting bases 2, and a runner 15 is rotatably installed in each wheel groove. The lifting base 2 is abutted against the outer side of the flower bed through the runner 15 to reduce the friction force. At the front and rear ends of the top surface of each lifting base 2, an internally hollow positioning cylinder 16 is fixedly installed. One end of each positioning cylinder 16 facing the other lifting base 2 is open, 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 is connected inside the positioning rod 17 and the positioning cylinder 16. As shown in the attached Figure 9 figure, during the process of abutting the lifting base 2 against the outer side of the flower bed, the handle can be pulled to pull the positioning rod 17 outwards from the positioning cylinder 16 and abut the positioning wheel 18 against the inner side of the flower bed. The positioning tension spring 19 is stretched and stores energy. Under the action of the elastic force of the positioning tension spring 19, the lifting base 2 will not be separated from the outer side of the flower bed during the movement process and when being squeezed by obstacles to the left and right sides. And different lengths of the pulled-out positioning rod 17 are suitable for flower beds of different widths.

[0058] As shown in the attached Figure 10As shown, a trimming adjustment groove 20 is formed at the top of the lifting base 2. A trimming adjustment screw block 21 located within the trimming adjustment groove 20 is fixedly installed at the bottom of the side trimming box 3. A trimming adjustment lead screw 22 that is in threaded cooperation with the trimming adjustment screw block 21 is rotatably installed within the trimming adjustment groove 20. The trimming adjustment lead screw 22 is connected to a trimming adjustment motor 23. The trimming adjustment motor 23 is electrically connected to the storage battery and can be remotely controlled via a remote controller. When it is started, it can drive the trimming adjustment lead screw 22 to rotate, and the trimming adjustment screw block 21 that is in threaded cooperation with it can move within 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, so as to change the trimming length of the side of the green plant. A groove protection piece 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 piece 24 to expand and contract, and it can protect the trimming adjustment groove 20 to prevent the cut green plants from falling into it.

[0059] As shown in the attached Figure 1 、 Figure 3 、 Figure 7 As shown, lifting drive boxes 25 are fixedly installed on the opposite sides of the two side trimming boxes 3. A lifting lead screw 26 is rotatably installed within the lifting drive box 25. Each lifting trimming box 4 is fixedly installed with a lifting screw block 27 located within the lifting drive box 25 and in threaded cooperation with the lifting lead screw 26. The lifting lead screw 26 is connected to a lifting motor 28. The lifting motor 28 is electrically connected to the storage battery and can be remotely controlled via a remote controller. When it is started, it can drive the lifting lead screw 26 to rotate, driving the lifting screw block 27 that is in threaded cooperation with it to move up and down within the lifting drive box 25, thereby driving the lifting trimming box 4 to move up and down for height adjustment.

[0060] As shown in the attached Figure 1 、 Figure 8 As shown, trimming grooves 29 are formed on the front and rear sides of each of the side trimming box 3, the lifting trimming box 4, the horizontal trimming box 5, and the obstacle avoidance trimming box 6. During moving trimming, the green plants can enter the interiors of the multiple trimming boxes from the trimming grooves 29, and thus be trimmed by the trimming chain saw 7. And a plurality of protection pieces 30 are installed within each trimming groove 29. The protection pieces 30 are made of rubber material and can prevent the green plants from splashing everywhere during trimming. As shown in the attached Figure 3 As shown, through grooves are formed at the bottom ends of the outer sides of the side trimming box 3 and the lifting trimming box 4 for discharging the branches and leaves inside them after trimming. Each trimming chain saw 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 can be used as the power. The power source 31 can drive the trimming chain saw 7 to rotate. The lifting trimming box 4 and the horizontal trimming box 5 are fixedly connected by a triangular rib plate 32. The triangular rib plate 32 and the two are fixed by bolts.

[0061] As shown in the appendix Figure 14 As shown, slide rails 33 are fixedly installed on the front and rear sides of each horizontal trimming box 5. The obstacle avoidance trimming box 6 is slidably connected to the slide rails 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 shown in the appendix Figures 4 - 7 、 Figures 11 - 14 As shown, the obstacle avoidance assembly 8 includes a front obstacle avoidance pressing plate 34, a front obstacle avoidance inclined surface 35, a rear obstacle avoidance pressing plate 36, and a rear obstacle avoidance inclined surface 37;

[0063] Front obstacle avoidance pressing plates 34 are fixedly installed on the front sides of the two obstacle avoidance trimming boxes 6. The ends of the two front obstacle avoidance pressing plates 34 close to each other are abutted against each other under the elastic force of the elastic adjustment assembly 9, and are respectively provided with front obstacle avoidance inclined surfaces 35 facing forward;

[0064] Rear obstacle avoidance pressing plates 36 are slidably installed on the slide rails 33 on the rear sides of each horizontal trimming box 5. The ends of the two rear obstacle avoidance pressing plates 36 close to each other are abutted against each other under the elastic force of the elastic adjustment assembly 9, and are respectively provided with rear obstacle avoidance inclined surfaces 37 facing forward;

[0065] As shown in the appendix Figure 4 As shown, during the process of moving forward for trimming, a columnar obstacle is about to abut against the two front obstacle avoidance inclined surfaces 35. As shown in the appendix Figure 5 As shown, after the two front obstacle avoidance inclined surfaces 35 abut against the obstacle, they are pushed to the left and right sides by the obstacle, so as to drive the two obstacle avoidance trimming boxes 6 to separate to the left and right sides. The obstacle can pass through between the two obstacle avoidance trimming boxes 6. At this time, the two rear obstacle avoidance pressing plates 36 still abut against each other, ensuring 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 inclined surfaces 35 are reset to close to the middle under the elastic force of the elastic adjustment assembly 9;

[0066] Then the obstacle can abut against the two rear obstacle avoidance inclined surfaces 37 and push the two rear obstacle avoidance pressing plates 36 to the left and right sides, so that the obstacle passes through. Finally, the two rear obstacle avoidance pressing plates 36 are reset to close to the middle under the elastic force of the elastic adjustment assembly 9, so as to realize the automatic avoidance operation of the obstacle during the trimming process.

[0067] As shown in the appendix Figure 13As shown, connection slots 38 are provided on the abutting surfaces of one of the front obstacle avoidance extrusion plates 34 and one of the rear obstacle avoidance extrusion plates 36. Wedge-shaped inserts 39 are fixedly installed on the abutting surfaces of the other front obstacle avoidance extrusion plate 34 and rear obstacle avoidance extrusion plate 36. The wedge-shaped inserts 39 have inclined surfaces facing forward. Through the insertion of the wedge-shaped inserts 39 into the connection slots 38, when the two front obstacle avoidance extrusion plates 34 or the two rear obstacle avoidance extrusion plates 36 are separated to the two sides, the other set of non-separated wedge-shaped inserts 39 and the connection slots 38 are in an inserted and mating state, which can ensure that the front and rear positions of the two mobile carts 1, the lifting base 2, and the two horizontal pruning boxes 5 are consistent, so that the separated wedge-shaped inserts 39 and the connection slots 38 can be smoothly closed and inserted;

[0068] Limit semi-circular grooves 40 are provided on the upper and lower inner walls of each connection slot 38. Limit holes 41 are provided on the upper and lower sides of each wedge-shaped insert 39. Limit springs 42 are fixedly installed in each limit hole 41. Limit balls 43 that abut against the limit springs 42 are embedded and installed on the inner sides of the openings of each limit hole 41;

[0069] When the soil inside the flower bed is flush with the top of the flower bed, the positioning wheels 18 cannot be stuck inside the flower bed to provide fixation and positioning for the mobile carts 1 and the lifting base 2. At this time, the positioning rods 17 do not need to be pulled outwards, and the positioning wheels 18 can abut against the outer side of the flower bed like the rotating wheels 15. When the two front obstacle avoidance extrusion plates 34 are squeezed by an obstacle, it is very likely that the two front obstacle avoidance extrusion plates 34 and the two rear obstacle avoidance extrusion plates 36 will be simultaneously pushed to the left and right sides, causing all the equipment on both sides of the green belt to move outwards and unable to automatically close and reset to the middle. Therefore, while the connection slots 38 and the wedge-shaped inserts 39 are inserted and mated, the cooperation between the limit balls 43 and the limit holes 41 provides a limiting force in the left and right directions for the connection slots 38 and the wedge-shaped inserts 39. When the two front obstacle avoidance extrusion plates 34 are squeezed by an obstacle and separated to the left and right sides, the two rear obstacle avoidance extrusion plates 36 remain in an abutting state under the limiting action between the limit balls 43 and the limit holes 41;

[0070] Bolt fixing seats 44 are fixedly installed at the tops of the mutually abutting ends of the two front obstacle avoidance extrusion plates 34 and at the tops of the mutually abutting ends of the two rear obstacle avoidance extrusion plates 36. Fixing bolts 45 are detachably installed between every two abutting bolt fixing seats 44. When there are obstacles in the green belt and obstacle avoidance is not required, the two bolt fixing seats 44 can be connected by screwing the fixing bolts 45 at this time, so as to connect the equipment on both sides of the green belt into a whole equipment, and then the green belt can be trimmed.

[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 return 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] A spring plate 46 is slidably mounted on each of the slide rails 33. An obstacle avoidance spring rod 47 is fixedly connected to each of the obstacle avoidance trimming boxes 6 and each of the rear obstacle avoidance pressing plates 36. Each of the obstacle avoidance spring rods 47 passes through the corresponding spring plate 46. An obstacle avoidance return spring 48 that abuts against the spring plate 46 is sleeved on the outer side of each of the obstacle avoidance spring rods 47. When the distance between the two horizontal trimming boxes 5 changes, the position of the spring plate 46 can be slid to make the two obstacle avoidance trimming boxes 6 and the two rear obstacle avoidance pressing plates 36 abut again. After the spring plate 46 is positioned, when an obstacle presses the two front obstacle avoidance pressing plates 34 or the two rear obstacle avoidance pressing plates 36 to separate to the left and right sides, the two obstacle avoidance trimming boxes 6 and the two rear obstacle avoidance pressing plates 36 drive the obstacle avoidance spring rods 47 to move towards the spring plate 46 and compress the obstacle avoidance return spring 48. After the obstacle passes, the two obstacle avoidance trimming boxes 6 and the two rear obstacle avoidance pressing plates 36 can close towards the middle under the elastic force of the obstacle avoidance return spring 48 and reset to the abutting state;

[0073] An internally hollow spring plate adjustment box 49 is fixedly installed on the top of each of the horizontal trimming boxes 5. A spring plate adjustment block 50 is slidably mounted left and right inside each of the spring plate adjustment boxes 49. Spring plate adjustment grooves 51 penetrate between the front and rear sides of the spring plate adjustment box 49 and its interior. Spring plate adjustment rods 52 that pass through the two spring plate adjustment grooves 51 are fixedly installed on the front and rear sides of the spring plate adjustment block 50. Each of the spring plate adjustment rods 52 is fixedly connected to the top of the spring plate 46 on the corresponding side. A spring plate lead screw 53 that is in threaded cooperation with the spring plate adjustment block 50 is rotatably installed inside each of the spring plate adjustment boxes 49. Each of the spring plate lead screws 53 is connected to a spring plate motor 54. The spring plate motor 54 is electrically connected to the storage battery and can be remotely controlled by a remote control. When it is started, it can drive the spring plate lead screw 53 to rotate, thereby driving the spring plate adjustment block 50 to move left and right inside the spring plate adjustment box 49. The spring plate adjustment block 50 drives the spring plate 46 to move through the spring plate adjustment rods 52 fixed on its front and rear sides, thereby realizing the position adjustment of the spring plate 46.
