Description

Technical Field

[0001] The present invention relates to the technical field of green belt pruning, and in particular to a fully automatic pruning device and pruning method for the greening of a central dividing strip of an expressway. Background Art

[0002] Greenery in medians often beautifies roads. Proper pruning can keep plants neat and beautiful, preventing excessive growth of weeds and plants that would otherwise unsightly the road surface. Overgrown greenery on highways, especially grass and shrubs, can obstruct drivers' vision, especially at intersections, ramps, and turns. Regular pruning maintains visibility and ensures safe driving. Therefore, pruning greenery in highway medians is a crucial maintenance task, ensuring road safety, a beautiful environment, and the healthy growth of plants. At the same time, due to the high speeds of traffic on highways, pruning greenery in central medians poses a significant safety hazard. Temporary road closures can also cause inconvenience to vehicles.

[0003] In the existing technology, with the development of drone technology, by using drones equipped with pruning modules and intelligent control systems, and utilizing the drone's flight capabilities and high-precision positioning technology, the green plants in the central dividing strip of the highway can be automatically identified and located. After positioning is completed, the drone will land accurately so that the green belt falls between two sets of side pruning devices. At the same time, the drone will automatically adjust the height and angle of the pruning module through the intelligent control system according to the preset pruning height and shape parameters, and accurately prune the green plants.

[0004] The above scheme still has some problems in actual application. Although the existing device can complete the pruning work of the green belt, due to the large traffic volume and high speed on the highway, some drivers will discard garbage at will, such as plastic bags, beverage bottles, etc. These garbage will fall on the top of the plants in the central dividing strip under the wind. When the pruning disc collides with these debris, scratches, gaps or even breaks will appear on the surface of the disc. This physical damage will not only reduce the service life of the pruning disc, but also affect its pruning effect and accuracy. Summary of the Invention

[0018] Description of Reference Numerals DETAILED DESCRIPTION

[0019] The following describes the specific implementation of the embodiment of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the embodiment of the present invention and is not used to limit the embodiment of the present invention.

[0020] Figure 1 1 is a schematic structural diagram of a fully automatic mowing device for greening a highway central dividing strip according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the structure of the trimming mechanism in the fully automatic trimming device for greening the central median strip of a highway according to one embodiment of the present invention. Figure 1 and Figure 2 In the figure, the fully automatic trimming device may include a drone body 101, a shell 102, a swinging and pushing mechanism, and a trimming mechanism.

[0021] The housing 102 is located at the bottom of the drone body 101 and is in an inverted U-shape. A swinging and pushing mechanism is located at one end of the housing 102, i.e., the end in which the housing 102 moves, and is used to push and collect debris from the green belt. A trimming mechanism is located on the inner walls of the housing 102, including the top wall and two opposing inner walls, and is used to trim and collect debris from the top and sides of the green belt.

[0022] When the green belt needs to be trimmed, the drone body 101 is driven to fly to the area of the green belt to be trimmed, and the outer shell 102 is placed on the outside of the green belt. First, the swinging and pushing mechanism is activated to swing and clean the debris on the top of the green belt to be trimmed, and at the same time, the cleaned debris is collected and processed to prevent the debris from falling to the ground and increasing the number of cleaning times. Then the trimming mechanism is activated to trim the top and sides of the green belt to be trimmed. Similarly, the trimming mechanism will also collect and recycle the trimmed branches to avoid interference with roads and vehicles. The drone body 101 is driven to fly along the trimming route to trim the current green belt area to be trimmed until the trimming task is completed. After the trimming is completed, the drone body 101 is driven to return or fly to the next green belt area to be trimmed.

[0023] Traditional green belt pruning methods employ drones equipped with pruning modules and intelligent control systems. Leveraging the drone's flight capabilities and high-precision positioning technology, the drone automatically identifies and locates green plants in highway medians. The intelligent control system automatically adjusts the height and angle of the pruning module, enabling precise pruning of the plants. However, due to the high volume and speed of traffic on highways, some drivers casually discard trash, such as plastic bags and beverage bottles. This debris, blown by the wind, can drift onto the tops of plants in the median. When the pruning disc collides with this debris, it can cause scratches, nicks, or even breakage on the disc's surface. This physical damage not only reduces the disc's service life but also affects its pruning effectiveness and accuracy. In this embodiment of the present invention, a swinging push-off mechanism is used to sweep and collect debris from the green belt. This effectively reduces the amount of debris that interferes with the pruning mechanism, improving pruning efficiency and effectiveness. It also protects the pruning mechanism, increasing its service life and reliability.

[0024] In this embodiment of the invention, Figure 1 、 Figure 3 、 Figure 5 as well as Figure 7 As shown, the swinging and pushing mechanism may include a swinging plate 209, multiple groups of comb teeth 210, a swinging mechanism and a collecting mechanism.

[0025] A swing plate 209 is disposed within the housing 102, with one end of the swing plate 209 extending beyond the housing 102. Specifically, the extension direction of the swing plate 209 is parallel to the extension direction of the housing 102. Multiple sets of comb teeth 210 are evenly spaced and arranged at the bottom of the swing plate 209. Specifically, the multiple sets of comb teeth 210 are serrated. A swing mechanism is disposed within the top of the inverted U-shaped housing 102. The output end of the swing mechanism is connected to the other end of the swing plate 209, driving the swing plate 209 to reciprocate. A collection mechanism is disposed below the swing mechanism and cooperates with the swing plate 209 to collect debris.

[0026] When debris on top of the green belt needs to be cleaned, the swing mechanism is activated to drive the swing plate 209 to swing back and forth. As the swing plate 209 swings back and forth, it clears debris from the top of the green belt. Simultaneously, the collection mechanism collects debris as the swing plate 209 swings and collects it, preventing it from falling to the ground and impacting road safety. Furthermore, as the swing plate 209 swings, it simultaneously drives multiple sets of comb teeth 210 to comb out intertwined branches within the green belt, further reducing the complexity of pruning and improving pruning efficiency.

[0027] In this embodiment of the invention, Figure 3 and Figure 5 As shown, the swing mechanism may include a guide base 201, a rack 204, two sets of support bases 205, a gear 206, a rotating rod 207 and a driving mechanism. Specifically, the guide base may include a guide groove.

[0028] The guide seat 201 is arranged at the inner top of one end of the outer shell 102. A guide groove is provided on one side of the guide seat 201. Specifically, the sliding direction of the guide seat 201 and the guide groove is perpendicular to the moving direction of the outer shell 102. The rack 204 is slidably arranged inside the guide groove. Two groups of support seats 205 are arranged on one side of the guide seat 201 and are distributed up and down. The gear 206 is rotatably arranged between the two groups of support seats 205 and is meshed with the rack 204. The rotating rod 207 is arranged below the support seat 205. The top end of the rotating rod 207 movably passes through the support seat 205 located below and is connected to the gear 206. The bottom end of the rotating rod 207 is connected to the swing plate 209. The driving mechanism is arranged on the guide seat 201, and the output end is connected to the end of the rack 204, which is used to drive the rack 204 to slide back and forth along the extension direction of the guide seat 201.

[0029] When it is necessary to drive the swing plate 209 back and forth to clear debris from the top of the green belt, the drive mechanism is activated. The drive mechanism drives the rack 204 to slide back and forth along the extension direction of the guide base 201. Due to the meshing action of the gear 206 and the rack 204, the reciprocating movement of the rack 204 drives the gear 206 to rotate synchronously. During this synchronous reciprocating rotation, the gear 206 drives the swing plate 209 to swing back and forth synchronously via the rotating rod 207, thereby achieving the purpose of clearing debris. Specifically, the travel distance of the rack 204 can include the meshing distance corresponding to a 180° rotation of the drive gear 206.

[0030] In this embodiment of the invention, Figure 3 and Figure 5As shown, the bottom end of the rotating rod 207 is provided with a conical blocking piece 208. Specifically, the conical blocking piece 208 can block falling objects and guide them to other positions to protect the connection between the rotating rod 207 and the swing plate 209, thereby effectively improving the reliability of the rotating rod 207 and the swing plate 209.

[0031] In this embodiment of the invention, Figure 3 and Figure 5 As shown, the driving mechanism may include an electric cylinder 202 and a fixing rod 203 .

[0032] The electric cylinder 202 is disposed on the guide seat 201 , one end of the fixing rod 203 is connected to the end of the rack 204 , and the other end of the fixing rod 203 is connected to the output end of the electric cylinder 202 .

[0033] When the rack 204 needs to be driven to slide to drive the gear 206 to rotate, the electric cylinder 202 is activated, and the electric cylinder 202 drives the rack 204 to slide along the guide groove through the fixed rod 203. The use of the electric cylinder 202 and the fixed rod 203 to drive the rack 204 can effectively improve the convenience and reliability of the sliding of the rack 204.

[0034] In this embodiment of the invention, Figure 1 As shown, the collecting mechanism may include a blocking plate 307 , two sets of first collecting frames 308 and a guiding mechanism.

[0035] The blocking plate 307 is mounted on the inner wall of the housing 102, with its bottom surface flush with the bottom surface of the swing plate 209. The dimensions of the blocking plate 307 and the swing plate 209 are compatible. Two sets of first collection frames 308 are located at either end of the blocking plate 307. A guide mechanism is provided on the sidewall of the swing plate 209, which cooperates with the rotating rod 207 to transport debris into the first collection frames 308.

[0036] As the swing plate 209 swings, debris is collected on one side of the swing plate 209 until the swing plate 209 is parallel to the baffle 307. At this point, debris is located between the baffle 307 and the swing plate 209. By activating the guide mechanism, the debris between the baffle 307 and the swing plate 209 is transported to the corresponding first collection frame 308, thereby cleaning and collecting the debris. Because two sets of first collection frames 308 are located at either end of the baffle 307, debris is collected and transported to the two first collection frames 308 during the reciprocating swing of the swing plate 209. The coordination between the swing plate 209 and the baffle 307 to define the collection area and the guide mechanism to transport the debris to the first collection frames 308 effectively improves the convenience and effectiveness of debris collection. This prevents debris from the green belt from falling to the ground when the swing plate 209 swings, thereby reducing the number of subsequent cleaning operations and the time and cost of pruning.

[0037] In this embodiment of the invention, Figure 7 and Figure 8 As shown, the guide mechanism may include four sets of fixed plates 301 , two sets of first rotating columns 303 , two sets of second rotating columns 305 , two sets of conveyor belts 304 , two sets of motors 302 and multiple sets of positioning plates 306 .

[0038] Four sets of fixed plates 301 are arranged in pairs on either side of the swing plate 209, arranged vertically. Specifically, two sets of fixed plates 301 are arranged on one side of the swing plate 209, with the two sets of fixed plates 301 on one side of the swing plate 209 arranged vertically. Two sets of first rotating posts 303 are respectively arranged on either side of one end of the swing plate 209, with the ends of the first rotating posts 303 rotatably connected to the opposite sides of the corresponding two sets of fixed plates 301. Two sets of second rotating posts 305 are respectively arranged on either side of the other end of the swing plate 209, with the ends of the second rotating posts 305 rotatably connected to the opposite sides of the corresponding two sets of fixed plates 301. Two sets of conveyor belts 304 are respectively mounted on the outside of the first rotating posts 303 and the second rotating posts 305 on the same side of the swing plate 209, including but not limited to methods such as meshing connection between the first rotating posts 303 and the second rotating posts 305 and the conveyor belts 304, or friction-tension transmission. Two motors 302 are mounted on two upper fixed plates 301, with the outputs of the motors 302 moving through the corresponding fixed plates 301 and connected to the corresponding first rotating column 303 or second rotating column 305. Multiple sets of positioning plates 306 are evenly arranged on the outside of the two conveyor belts 304.

[0039] When the swing plate 209 swings, debris can be separated and confined by the retaining plates 306 so that the debris is collected between two adjacent retaining plates 306. When the swing plate 209 rotates to be parallel to the blocking plate 307, the blocking plate 307, the swing plate 209, the multiple sets of retaining plates 306, and the top of the green belt cooperate to form multiple confined spaces. The motor 302 near the blocking plate 307 is started, and the motor 302 drives the corresponding first rotating column 303 or the second rotating column 305 to rotate, and then drives the corresponding second rotating column 305 or the first rotating column 303 to rotate through the conveyor belt 304, so as to push and transport the debris inside the multiple confined spaces and transport the debris one by one to the inside of the corresponding first collection frame 308. The use of the conveyor belt 304 in combination with the multiple sets of retaining plates 306 can achieve the zoning and confinement of debris and the stable transportation, further improving the effect and reliability of cleaning and collecting debris in the green belt.

[0040] In this embodiment of the invention, Figure 3 、 Figure 4 as well as Figure 6 As shown, the swing mechanism may further include a bidirectional oblique block 217, a water storage box 216, a piston cylinder 211, a piston plate 212, a piston rod 214, a reciprocating spring 213, and a spray head. Specifically, the piston cylinder 211 may include a water delivery pipe 215, and the piston rod 214 may include a bidirectional oblique surface.

[0041] A bidirectional oblique block 217 is disposed at the end of the rack 204, and a water storage box 216 is disposed at the inner top of the housing 102. A piston cylinder 211 is disposed within the housing 102, with the bottom end of the piston cylinder 211 connected to the water storage box 126 via a water pipe 215. A piston plate 212 is slidably disposed within the piston cylinder 211, and a piston rod 214 is disposed at the top end of the piston plate 212. The top of the piston rod 214 movably extends through the piston cylinder 211. The top end of the piston rod 214 is provided with a bidirectional oblique surface that movably engages the bidirectional oblique block 217. A reciprocating spring 213 is sleeved on the outside of the piston rod 214. One end of the reciprocating spring 213 is connected to the piston plate 212, and the other end of the reciprocating spring 213 is connected to the inner top wall of the piston cylinder 211. A spray nozzle is disposed on the side wall of the piston cylinder 211 and is connected to the bottom end of the piston cylinder 211. Specifically, the spray nozzle may include an atomizing nozzle.

[0042] As the rack 204 moves, it drives the bidirectionally inclined block 217 to move synchronously. The bidirectionally inclined block 217 gradually contacts the bidirectionally inclined surface at the top of the piston rod 214, pushing the piston rod 214 downward. As the piston rod 214 moves downward, it simultaneously pushes the piston plate 212 to squeeze the air at the bottom of the piston cylinder 211, thereby spraying the water from the bottom of the piston cylinder 211 out through the nozzle. Specifically, the nozzle's flattened outlet creates a fan-shaped mist. The mist falls on lighter debris, such as plastic bags, on the green belt. The added weight of these debris prevents the swing plate 209 from being blown away by the wind and causing them to flutter. This further improves the efficiency of the swing plate 209 and the effectiveness of debris collection. Furthermore, the return spring 213 compresses the piston rod 214 during its downward movement and resets it if it loses its restraint, providing increased flexibility and reliability.

[0043] In this embodiment of the present invention, in order for the nozzle to effectively spray water mist, the water level inside the piston cylinder 211 should be slightly lower than the nozzle outlet of the nozzle, so that when the piston rod 214 squeezes the internal space of the piston cylinder 211, it can drive the water to spray out stably. Furthermore, in order to improve the effectiveness and reliability of the piston rod 214 squeezing the internal space of the piston cylinder 211 to drive the water to spray out, a valve is provided on the water pipe 215. When the piston rod 214 moves downward, the valve is closed, the interior of the piston cylinder 211 is reliably squeezed, and the water can be pushed out along the nozzle by air pressure. When the piston rod 214 is reset, the valve opens, so that the water stored in the water storage box 216 is transported to the interior of the piston cylinder 211 through the water pipe, waiting for the next spray. Specifically, the valve may include but is not limited to a manual valve, an electric valve, etc.

[0044] In this embodiment of the present invention, the water storage box 216, the piston cylinder 211, the piston rod 214 and other matching structures can include two sets, and the two sets of matching structures are symmetrically arranged inside one end of the housing 102. The two sets of matching structures can achieve sufficient and effective spraying, further improving the working efficiency of the swing plate 209 during swinging and the effectiveness of collecting debris.

[0045] In this embodiment of the invention, Figure 1 and Figure 2 As shown, the trimming mechanism may include multiple sets of trimming discs 104 , a second collecting frame 105 and a suction mechanism.

[0046] Multiple sets of trimming discs 104 are disposed on two opposing inner walls and the inner top of the housing 102, and a second collection frame 105 is disposed on the top of the housing 102. A suction mechanism is disposed within the second collection frame 105, and a pipe is disposed at the output end of the suction mechanism. The pipe extends from the end away from the suction mechanism to the bottom end of the housing 102. Specifically, the pipe is disposed at the end of the housing 102 away from the swinging and pushing mechanism.

[0047] The trimming disc 104 can trim the top and sides of the green belt and perform continuous trimming as the housing 102 moves. After trimming is completed, the suction mechanism can suck the trimmed branches, leaves, etc. through the pipe and suck them into the second collection frame 105 for recycling, thereby ensuring the cleanliness and safety of the road.

[0048] In this embodiment of the present invention, the suction mechanism may include but is not limited to a vacuum pump and the like.

[0049] In this embodiment of the present invention, the trimming mechanism may include two groups, which are symmetrically arranged at one end of the housing 102 away from the swinging and pushing mechanism, and can cooperate to effectively absorb and collect the trimmed leaves, branches, etc.

[0050] In this embodiment of the invention, Figure 1 As shown, the housing 102 may include an anti-collision detector 103. Specifically, the anti-collision detector 103 is provided at the top of the housing 102, near one end of the swing-out mechanism. Specifically, the anti-collision detector 103 can detect obstacles ahead of the housing 102 in its moving direction. When the anti-collision detector 103 detects an obstacle ahead, it can drive the drone body 101 to move the housing 102 and its internal structure over the obstacle.

[0051] In this embodiment of the present invention, a photovoltaic panel is provided on the drone body 101, and the photovoltaic panel on the drone body 101 can provide corresponding energy support for the operation of the device.

[0052] In this embodiment of the invention, Figure 1 As shown, the bottom of the housing 102 may include a pulley, which can assist the movement of the drone body 101 to improve the convenience of moving the drone body 101.

[0053] On the other hand, the present invention also provides a method for trimming a green belt using the above-mentioned fully automatic trimming device for greening a central median strip of a highway. Specifically, Figure 9 As shown, the pruning method may include: In step S1, the flight altitude and speed of the drone body 101 and the trimming frequency of the trimming mechanism are configured. Before the drone body 101 takes off, the housing 102 can be selected according to the width of the green belt and assembled with the drone body 101.

[0054] In step S2 , the drone body 101 is driven to fly to the area of the green belt to be trimmed, and the housing 102 is sleeved on the outside of the green belt to be trimmed.

[0055] In step S3, the swinging and pushing mechanism is started to clean and collect debris on the green belt to be trimmed.

[0056] In step S4, the trimming mechanism is activated to trim and collect the top and sides of the green belt to be trimmed. The drone body 101 automatically adjusts the height and angle of the trimming module according to the preset trimming height and shape parameters through an intelligent control system known to those skilled in the art.

[0057] In step S5, the drone 101 is driven to move along the mowing route of the green belt to be mowed. During the mowing process, the anti-collision detector 103 continuously monitors the surrounding environment. Once it detects poles or other obstacles in the green belt, it immediately notifies the drone 101 to take off and cross, and the photovoltaic panels installed on the housing 102 continuously power the device.

[0058] In step S6, it is determined whether the current drone body 101 has moved to a preset position.

[0059] In step S7, when it is determined that the current drone body 101 has moved to the preset position, the drone body 101 is driven to return. If the current drone body 101 has moved to the preset position, it means that the current trimming task is completed, and the drone body 101 can be driven to return or fly to the next trimming area.

[0060] In step S8 , when it is determined that the current drone body 101 has not moved to the preset position, the process returns to the step of driving the drone body 101 to move along the trimming route of the green belt to be trimmed.

[0061] In steps S1 to S8, the parameters of drone body 101, such as flight altitude, speed, and trimming frequency, are first configured. Once configured, drone body 101 is driven to fly to the area of the green belt to be trimmed and positioned outside the green belt. The swinging and pushing mechanism is activated to clean and collect debris from the green belt, and the trimming mechanism is simultaneously activated to trim and collect the top and sides of the green belt. Simultaneously, drone body 101 is driven to fly / move along a preset trimming route to trim the green belt in the direction of its extension. Finally, the current real-time position of drone body 101 is determined to determine whether it is at the preset position / trimming endpoint. If so, the current trimming task is complete, and drone body 101 is driven to return home or fly to the next trimming area. Otherwise, drone body 101 is driven to fly and move along the original trimming route until the trimming task is completed.

[0062] Through the above technical solution, the fully automatic pruning device and pruning method for the greening of the central median strip of a highway provided by the present invention drives the drone body 101 to fly near the green belt to be pruned, and sets the shell 102 on the outside of the green belt to be pruned, activates the swinging and pushing mechanism, pushes and sweeps the debris on the top of the green belt to be pruned, and collects the pushed and swept debris; at the same time, activates the pruning mechanism to prune the top and sides of the green belt to be pruned, and collects the pruned branches and the like. The use of the swinging and pushing mechanism to clean and collect debris on the green belt can effectively reduce the interference of debris on the pruning mechanism, improve the pruning efficiency and pruning effect, and improve the convenience of cleaning for the collection of debris; at the same time, it protects the pruning mechanism and increases the service life and reliability of the pruning mechanism.
