Description

[0002] With the continuous advancement of urbanization construction in China, the status of landscaping in urban construction is becoming higher and higher. It beautifies the city while purifying the urban environment. In order to ensure the healthy growth and aesthetic appearance of flowers, trees and plants, part of the branches and leaves need to be pruned. For some tall trees, it also involves high-altitude operation.

[0003] For the pruning of branches and trunks in the air, there are currently two main ways. One is to connect a very long rod to the bottom of the tree pruning shears, and the garden maintenance personnel stand on the ground to hold the rod to prune the branches and trunks in the air. This way is difficult to master the pruning direction, causes great damage to the trees, and has a great work intensity. The other way is for the garden maintenance personnel to use a climbing tool to prune at a high place, which has a high risk coefficient and high work cost.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0034] Please refer to Figures 1-8 The present application provides a technical solution: a pruning and maintenance device for landscaping, comprising a support mechanism 1, a clamping mechanism 2, two sets of maintenance mechanisms 3, two sets of pruning mechanisms 4, and a remote control end. The clamping mechanism 2 is arranged at the top of the support mechanism 1, the two sets of maintenance mechanisms 3 and the two sets of pruning mechanisms 4 are arranged at the two ends of the clamping mechanism 2, the maintenance mechanism 3 is arranged outside the pruning mechanism 4, and the remote control end is electrically connected with the support mechanism 1, the clamping mechanism 2, the maintenance mechanism 3, and the pruning mechanism 4. The remote control end is used for controlling the support mechanism 1, the clamping mechanism 2, the maintenance mechanism 3, and the pruning mechanism 4 to perform corresponding operations. The clamping mechanism 2 is used for clamping pruned branches, trunks, and trees. The maintenance mechanism 3 is used for pruning branches and trunks. The pruning mechanism 4 is used for adsorbing debris generated during pruning and whitewashing trees.

[0035] Specifically, as Figure 1As shown, the support mechanism 1 includes a lifting vehicle 11, a hydraulic cylinder 12, a counterweight 13, a liquid storage tank 15, and a waste bin 16. The hydraulic cylinder 12 includes a fixed end and an output end. The top of the lifting vehicle 11 is hinged to the fixed end of the hydraulic cylinder 12. The counterweight 13 is fixedly connected to the bottom of the lifting vehicle 11. Two sets of telescopic support legs 14 are provided on each side of the support mechanism 1. The liquid storage tank 15 is fixedly connected to one side of the lifting vehicle 11. The waste bin 16 is fixed to the top of the liquid storage tank 15. The counterweight 13 is used to counterweight the support mechanism 1. The telescopic support legs 14 are used to provide support when the maintenance mechanism 3 is trimming. Thus, the stability of the support mechanism 1 is improved by setting the counterweight 13 and the telescopic support legs 14. The liquid storage tank 15 is used to store liquid, which can be insecticide, whitening agent, etc. The waste bin 16 is used to store adsorbed debris.

[0036] It should be noted that the telescopic support leg 14 can be a support leg that is lifted and supported by a cylinder; the lifting vehicle 11 is equipped with a steering wheel that drives its movement.

[0037] Specifically, such as Figures 2-4 As shown, the clamping mechanism 2 includes a support base 21, two sets of clamping bases 22, two sets of cylinders 23 and three sets of clamping components 24. The side of the support base 21 is hinged to the output end of the hydraulic cylinder 12, and one end of the support base 21 is hinged to the edge of the top of the lifting vehicle 11.

[0038] The two ends of the support seat 21 away from the lifting vehicle 11 are semi-circular, and the clamping seat 22 is also semi-circular. One semi-circular end of the support seat 21 away from the lifting vehicle 11 is hinged to one end of the semi-circular clamping seat 22. Two sets of cylinders 23 correspond to the hinge points of the two ends of the support seat 21 and the clamping seat 22, respectively. Cylinder 23 includes a fixed end and an output end. The fixed end of cylinder 23 is hinged to the periphery of the support seat 21, and the output end of cylinder 23 is hinged to the periphery of the clamping seat 22. The other ends of the clamping seat 22 and the support seat 21 are provided with interlocking connectors.

[0039] In actual operation, the hydraulic cylinder 12 extends and retracts to lift the support seat 21, driving the support seat 21 to adjust to different angles between the horizontal and vertical states; when the cylinder 23 extends, it controls the clamping seat 22 to rotate counterclockwise around the hinge with the support seat 21, so that the clamping seat 22 and the clamping seat 21 are disconnected, thus making the support seat 21 and the clamping seat 22 open, which is convenient for removing the pruned branches and trunks and continuing to clamp the branches and trunks to be pruned. When the cylinder 23 retracts, it controls the clamping seat 22 to rotate clockwise around the hinge with the support seat 21, so that the clamping seat 22 and the clamping seat 21 are connected, thus making the support seat 21 and the clamping seat 22 connected to form a closed state, which is convenient for clamping and protecting the branches and trunks to be pruned.

[0040] It should be noted that, to further ensure the protective condition when the support base 21 and the clamping base 22 are connected, a protective plate can be fixedly connected to the periphery of the support base 21 and the clamping base 22, such as... Figure 4 As shown, this allows the enclosed space formed by the support base 21 and the clamping base 22 to create a storage space that can accommodate pruned branches and trunks, thereby improving subsequent pruning efficiency.

[0041] Furthermore, such as Figure 5 As shown, the clamping assembly 24 includes a support rod 241, a second cylinder 242, and a first motor 243. The three sets of support rods 241 of the clamping assembly 24 are fixed at equal intervals on the support base 21 and the clamping base 22, wherein two sets of support rods 241 are fixedly connected to the support base 21, and one set of support rods 241 is fixedly connected to the clamping base 22.

[0042] Cylinder 242 includes a fixed end and an output end. The output end of cylinder 242 is hinged to support rod 241. Support rod 241 is provided with a through groove, and slide 244 is provided in the through groove. Slide 244 is slidably connected to support rod 241. The output end of cylinder 242 is fixedly connected to slide 244. Connecting rod 245 is hinged to slide 244. Connecting seat 247 is hinged to the other end of connecting rod 245. Two sets of connecting rods 246 are hinged above the through groove of support rod 241. The other end of connecting rod 246 is hinged to connecting seat 247. Track 248 is provided on connecting seat 247. Motor 243 is fixed to the side of connecting seat 247. The output end of motor 243 is connected to track 248 for transmission. The transmission connection is located inside connecting seat 247. The transmission connection can be a gear transmission connection or other connection methods that drive track 248 to rotate on connecting seat 247.

[0043] In actual operation, cylinder 242 extends, causing slide 244 to move upward in the through groove, causing connecting rod 245 to rotate counterclockwise around the hinge point with slide 244, and simultaneously causing connecting rod 246 to rotate clockwise around the hinge point with support rod 241, moving connecting seat 247 away from support rod 241 and providing support for connecting seat 247. This allows track 248 on connecting seat 247 to fit against the branches and trunks to be pruned, clamping the branches and trunks. Then, motor 243 starts, driving track 248 to rotate on connecting seat 247. This allows the clamping position of the branches and trunks to be adjusted while the clamping mechanism 2 moves as a whole, without affecting the clamped branches and trunks.

[0044] Supplementary explanation of the above structure: When the clamping mechanism 2 is in a vertical state, the lifting vehicle 11 is raised, causing the clamping mechanism 2 to move upward. At this time, the branches and trunks tend to move downward relative to the clamping mechanism 2. Simultaneously, the motor 243 is started to rotate forward, driving the track 248 to rotate clockwise and counterclockwise on the connecting seat 247. At this time, while clamping the branches and trunks, the track 248 can move upward on the branches and trunks, causing the clamping component 24 to move upward in the position of clamping the branches and trunks. Conversely, when the clamping mechanism is in a vertical state, the lifting vehicle 11 is raised, causing the track 248 to move upward on the branches and trunks. When the clamping mechanism 2 is in a vertical position, controlling the lifting vehicle 11 to descend lowers the clamping mechanism 2, causing it to move downwards. At this time, the branches and trunks tend to move upwards relative to the clamping mechanism 2. Simultaneously, controlling the motor 243 to start and reverse reverse allows the clamping component 24 to move downwards while holding the branches and trunks. Similarly, when the clamping mechanism 2 is in a horizontal position, controlling the lifting vehicle 11 to move away from the hinge point between the support base 21 and the lifting vehicle 11 causes the branches and trunks to move closer to the hinge point between the support base 21 and the lifting vehicle 11 relative to the clamping mechanism 2. The trend is such that the motor 243 starts rotating forward, driving the track 248 to rotate counterclockwise on the connecting seat 247. At this time, while clamping the branches and trunks, the track 248 moves along the branches and trunks away from the hinge point between the support seat 21 and the lifting vehicle 11, causing the clamping assembly 24 to move away from the hinge point between the support seat 21 and the lifting vehicle 11. Conversely, when the clamping mechanism 2 is in a horizontal state, the lifting vehicle 11 is controlled to move closer to the hinge point between the support seat 21 and the lifting vehicle 11. When the joint moves, the branches and trunks tend to move closer to the hinge point between the support base 21 and the lifting vehicle 11 relative to the clamping mechanism 2. At the same time, the motor 243 is controlled to start rotating forward, which allows the clamping component 24 to move the clamping position of the branches and trunks closer to the hinge point between the support base 21 and the lifting vehicle 11. When clamping branches and trunks in an inclined state, the clamping position of the branches and trunks can also be adjusted in the above manner, thereby achieving the effect of adjusting the clamping position while maintaining the clamping mechanism 2's clamping of the branches and trunks.

[0045] Specifically, such as Figure 3 , Figures 6-8 As shown, the maintenance mechanism 3 includes a connecting plate 31, a rotating component 32, a protective shell 33, two sets of paint components 34, and two sets of suction ports 35. The connecting plate 31 is fixed to the end of the support base 21. The rotating component 32 is disposed on the connecting plate 31. The protective shell 33 is disposed on the rotating component 32. The two sets of paint components 34 and the two sets of suction ports 35 are disposed on the protective shell 33. The connecting plate 31 is used to provide support. The rotating component 32 is used to drive the protective shell 33 and the paint components 34 and suction ports 35 on the protective shell 33 to rotate synchronously. The paint components 34 are used to provide auxiliary support and whitewash the branches and trunks to be pruned. The suction ports 35 are used to absorb the debris generated during pruning.

[0046] Furthermore, such as Figures 6-8 As shown, the rotating assembly 32 includes a second motor 321, an annular base 322, a rotating disk 323, a rotating shaft 324, and an extension plate 325. The second motor 321 is fixed to the side of the connecting plate 31 near the support base 21. The output end of the second motor 321 passes through the connecting plate 31 and is connected to the two sets of rotating shafts 324 via pulleys. The annular base 322 is fixed to the side of the connecting plate 31 away from the second motor 321. The rotating disk 323 is mounted on the annular base 322 and is slidably connected to the annular base 322. The two sets of rotating shafts 324 are connected to the rotating disk 323 via gears. The wheel drive connection is used. The extension plate 325 is fixed to the side of the rotating disk 323 away from the connecting plate 31. The extension plate 325 corresponds to the position of the second motor 321. Both the annular base 322 and the rotating disk 323 are arc-shaped. When the second motor 321 starts, it rotates clockwise, which drives the two sets of rotating shafts 324 to rotate clockwise through the pulley drive. Then, through the gear drive, it drives the rotating disk 323 to rotate counterclockwise on the annular base 322. Conversely, when the second motor 321 starts, it rotates counterclockwise, which can drive the rotating disk 323 to rotate clockwise on the annular base 322.

[0047] Furthermore, such as Figures 6-8 As shown, the protective shell 33 is arc-shaped and matches the shape of the rotating turntable 323. The protective shell 33 is fixed on the side of the rotating turntable 323 away from the support base 21. The protective shell 33 is provided with a limiting groove 331 on the side near the extension plate 325, and two sets of limiting grooves 332 are provided on the side of the protective shell 33 away from the connecting plate 31. The protective shell 33 is used to prevent debris from splashing when pruning branches and trunks and to receive the pruned branches and trunks.

[0048] Two sets of adsorption ports 35 are located inside the protective shell 33 on both sides. Each set of adsorption ports 35 has several ports. The adsorption ports 35 are connected to the waste bin 16 through pipes. The waste bin 16 is connected to an air extractor through pipes. When the air extractor is started, it can adsorb the debris generated when pruning branches and trunks, and the waste bin 16 will buffer it.

[0049] Furthermore, such as Figures 6-8As shown, the coating assembly 34 includes a connecting frame 341, a discharge pipe 342, a roller brush 343, and a torsion spring 344. One end of the connecting frame 341 is located inside the protective shell 33 and is rotatably connected to the protective shell 33. The torsion spring 344 is disposed on the end of the connecting frame 341 located inside the protective shell 33, and its two ends are respectively connected to the connecting frame 341 and the protective shell 33. The discharge pipe 342 is fixed to the end of the connecting frame 341 away from the protective shell 33. Several discharge ports 3421 are provided on the side of the discharge pipe 342 facing the center of the protective shell 33. The roller brush 343 is disposed on the discharge pipe 342. The discharge pipe 342 is connected to the bearing. When the limiting groove 332 and the connecting frame 341 rotate, the shape and position of the discharge pipe 342 match. The discharge pipe 342 is connected to the storage tank 15 through a pipeline. A liquid pump and a hydraulic sensor are installed on the pipeline connecting the discharge pipe 342 and the storage tank 15. Both the hydraulic sensor and the liquid pump are electrically connected to the remote control terminal. The hydraulic sensor is installed on the pipeline connecting the output end of the liquid pump and the discharge pipe 342. The liquid pump is used to pump the liquid inside the storage tank 15 into the discharge pipe 342. The hydraulic sensor is used to detect the liquid pressure at the output end of the discharge pipe 342, thereby controlling the intelligent start and stop of the liquid pump.

[0050] In actual operation, when the clamping mechanism 2 clamps the pruned branches and trunks, the discharge pipe 342 contacts the pruned branches and trunks and, under the action of the branches and trunks, drives the connecting frame 341 to rotate towards the side closer to the suction port 35 inside the protective shell 33, further ensuring that the discharge pipe 342 on the paint assembly 34 can fit the pruned branches and trunks; after the pruning is completed, the control cylinder 23 starts to extend, so that the support seat 21 and the clamping seat 22 are in the open state, and the connecting frame 341 can return to the initial state under the elastic force of the torsion spring 344. The initial state is that the discharge pipe 342 is flush with the end of the protective shell 33. At this time, since the discharge pipe 342 still plays an auxiliary support role for the pruned branches and trunks, the branches and trunks supported by the two sets of discharge pipes 342 can spring up under the elastic force of the torsion spring 344, making it convenient for the staff to take out the pruned branches and trunks;

[0051] The liquid inside the discharge pipe 342 can flow out from the discharge port 3421 to wet the roller brush 343. However, since the discharge port 3421 is located on the side facing the center of the protective shell 33, when the clamping mechanism 2 clamps the branches and trunks, the roller brush 343 is squeezed by the clamped branches and trunks. Under the squeezing action of the branches and trunks, the roller brush 343 can only be wetted at the discharge port 3421, and the liquid inside the discharge pipe 342 cannot flow out from the discharge port 3421. This causes the hydraulic pressure on the pipeline between the discharge pipe 342 and the output end of the liquid pump to increase. When the hydraulic pressure detected by the hydraulic sensor reaches a certain value, the specific hydraulic pressure value is set by the operator and fed back to the remote control terminal, which then controls the liquid pump to stop running. When the rotating component 32 drives the rotating turntable 323 to rotate the protective shell 33, the roller brush 343 comes into contact with the branches and trunks, and the surface of the branches and trunks... The roughness leads to friction. Since the connecting frame 341 and the protective shell 33 are connected by a torsion spring 344, when the protective shell 33 rotates, the friction between the roller brush 343 and the branches and trunks causes the connecting frame 341 to rotate around the connection point with the protective shell 33. This changes the radial clamping position of the roller brush 343 on the branches and trunks, as well as the contact position of the roller brush 343 with the branches and trunks. This allows the liquid inside the discharge pipe 342 to be used again to wet the squeezed area through the discharge port 3421, thereby reducing the hydraulic pressure on the pipeline between the discharge pipe 342 and the output end of the liquid pump. When the hydraulic pressure drops to a certain value, the specific hydraulic pressure value is set by the operator and fed back to the remote control terminal. The remote control terminal then controls the liquid pump to start, pumping the liquid inside the storage tank 15 into the discharge pipe 342, thus realizing the intelligent start and stop of the liquid pump and the circumferential brushing of the branches and trunks.

[0052] Specifically, such as Figure 8 As shown, the pruning mechanism 4 includes a movable base 41, a rotary table 42, and an electric saw 43. The movable base 41 is fixed to the side of the extension plate 325 away from the connecting plate 31. The rotary table 42 is fixed to the side of the movable base 41 away from the connecting plate 31. The electric saw 43 is fixed to the side of the rotary table 42 away from the connecting plate 31. The movable base 41 is used to drive the electric saw 43 to move along the setting direction of the movable base 41. The electric saw 43 corresponds to the position of the limiting groove 331. The movable base 41 can be a movable base with motor and lead screw drive. The rotary table 42 is used to drive the electric saw 43 to rotate, thereby adjusting the pruning direction of the electric saw 43. The rotary table 42 can be a rotary base with motor and pulley drive. The electric saw 43 is used to prune branches and trunks.

[0053] Additional explanation of the above structure: The operator can remotely control the chainsaw 43 to start, control the moving base 41 to move towards the arc-shaped opening of the protective shell 33, and simultaneously control the rotary table 42 to drive the chainsaw 43 to rotate, so that the chainsaw 43 can prune branches and trunks. If necessary, the operator can also control the motor 321 to start, drive the pruning mechanism 4 to adjust the pruning position as a whole, and drive the chainsaw 43 to move towards the arc-shaped opening of the protective shell 33 and rotate the chainsaw 43 via the rotary table 42, which can adapt to the pruning of branches and trunks of different diameters.

[0054] When the clamping mechanism 2 clamps the branches and trunks and the paint assembly 34 provides auxiliary support for the branches and trunks, the paint assembly 34 rotates towards the side of the protective shell 33 closer to the adsorption port 35, which can make the trimmed area of ​​the branches and trunks form a relatively closed space, with only the limit groove 331 and both ends of the protective shell 33 being open. At this time, the air pump is started, which can adsorb the debris generated during trimming through the adsorption port 35 into the waste bin 16 for buffering. By setting the paint assembly 34 and the protective shell 33, the flying debris generated during trimming can be further prevented.

[0055] When the clamping mechanism 2 is in a horizontal state, if the clamping mechanism 2 is in a closed state, it can clamp the branches and trunks to be pruned and is suitable for pruning thick branches; if the clamping mechanism 2 is in an open state, it can catch the branches and trunks that have been pruned and is suitable for pruning small branches and trunks, thereby preventing the pruned branches and trunks from falling. When a certain amount of branches and trunks are clamped and caught inside the clamping mechanism 2, the lifting vehicle 11 is controlled to move and lift, and the pruned branches and trunks are removed, thereby avoiding the branches and trunks from falling directly and causing injury to the workers during pruning.

[0056] When the clamping mechanism 2 is in a vertical position, it clamps the branches and trunks. Then, by starting the second control motor 321, driving the rotating turntable 323 to rotate, controlling the lifting vehicle 11 to rise and fall, starting the first motor 243 to drive the track 248 to rotate, and starting the liquid pump, the liquid inside the storage tank 15 can be brushed onto the surface of the branches and trunks. This is suitable for whitewashing the branches and trunks of tall trees and brushing on pesticides. If the second control motor 321 is started, driving the rotating turntable 323 to rotate, controlling the lifting vehicle 11 to rise and fall, starting the first motor 243 to drive the track 248 to rotate, and starting the air pump, the surface of the branches and trunks can be cleaned, and the generated debris can be absorbed and recycled. This prevents the branches and trunks from developing diseases and pests due to the long-term presence of dead bark and debris on the surface. This is suitable for cleaning the surface of branches and trunks.

[0057] It should be noted that, in actual use, the maintenance mechanism 3 and the trimming mechanism 4 can be installed only at the end of the support base 21 near the hinge with the lifting vehicle 11 and at the end away from the hinge with the lifting vehicle 11, depending on actual needs, thereby meeting a variety of usage needs; in actual use, this includes, but is not limited to, the usage methods described above.

[0058] The above methods can be used to prune high-altitude branches in landscaping, while also clamping branches and trunks during the pruning process and absorbing flying debris to prevent injury to workers from flying debris and falling branches. Additionally, it can be used to whitewash trees when necessary, reducing the labor intensity of workers and thus improving the efficiency and safety of pruning high-altitude branches and trunks in landscaping.
