Description

Technical Field

[0001] The invention relates to the technical field of pruning and maintenance of garden greening, in particular to a pruning and maintenance device for garden greening. Background Art

[0002] With the continuous advancement of urbanization in my country, the status of landscaping in urban construction is becoming increasingly higher. While beautifying the city, it also purifies the urban environment. In order to ensure the healthy growth and beauty of flowers, plants and trees, some branches and leaves need to be pruned. For some taller trees, high-altitude operations are also involved.

[0003] There are currently two main methods for pruning branches and trunks at high altitudes. One is to connect a very long rod under the pruning shears, and the garden maintenance staff stand on the ground and use the rod to prune the branches and trunks at high altitudes. This method is difficult to grasp the pruning direction, causes great damage to the trees, and is very labor-intensive. The other is for garden maintenance staff to use climbing tools to prune at high altitudes, which is very dangerous and has high work costs.

[0004] Furthermore, current pruning shears can only prune in a fixed direction and cannot prune flexibly at all angles. Constant intervention and adjustment are required during the pruning process. Furthermore, they cannot protect leaves and branches from being pruned, resulting in flying debris and falling branches, which poses a risk to workers and reduces the safety and utilization of garden pruning devices.

[0021] Specifically, such 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 tank 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 groups of telescopic support legs 14 are provided on both sides of the support mechanism 1. The liquid storage tank 15 is fixedly connected to one side of the lifting vehicle 11. The waste tank 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 pruning. The stability of the support mechanism 1 is improved by arranging the counterweight 13 and the telescopic support legs 14. The liquid storage tank 15 is used to store liquid, which can be an insect repellent liquid, a whitening agent, etc. The waste tank 16 is used to store adsorbed debris.

[0022] It should be noted that the telescopic support legs 14 may be support legs driven by cylinders to lift and lower for support; the lifting vehicle 11 is provided with a steering wheel to drive its movement.

[0023] Specifically, such as Figure 2-Figure 4 As shown, the clamping mechanism 2 includes a support base 21, two groups of clamping bases 22, two groups of cylinders 23 and three groups of clamping assemblies 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; The two ends of the support seat 21 away from the lifting vehicle 11 are semicircular, and the clamping seat 22 is also semicircular. The semicircular end of the support seat 21 away from the lifting vehicle 11 is hinged to one end of the semicircular clamping seat 22. The two groups of cylinders 1 23 correspond to the hinges of the two ends of the support seat 21 and the clamping seat 22 respectively. Cylinder 1 23 includes a fixed end and an output end. The fixed end of cylinder 1 23 is hinged to the periphery of the support seat 21, and the output end of cylinder 1 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 mutually clamped joints.

[0024] In actual operation, the hydraulic cylinder 12 is extended and retracted to prop up the support seat 21 and drive the support seat 21 to adjust to different angles between the horizontal state and the vertical state; when the cylinder 12 is extended, it can control the clamping seat 22 to rotate counterclockwise around the hinge with the support seat 21, so that the clamping seat 22 and the support seat 21 are disconnected, so that the support seat 21 and the clamping seat 22 are in an open state, which is convenient for removing the pruned branches and trunks and continuing to clamp the subsequent branches and trunks to be pruned. When the cylinder 123 is contracted, it can control the clamping seat 22 to rotate clockwise around the hinge with the support seat 21, so that the clamping seat 22 is connected to the support seat 21, so that the support seat 21 and the clamping seat 22 are connected to form a closed state, which is convenient for clamping and protecting the branches and trunks to be pruned.

[0025] It should be noted that, in order to further ensure the protective state when the support seat 21 and the clamping seat 22 are connected, the periphery of the support seat 21 and the clamping seat 22 can be fixedly connected with a protective plate, such as Figure 4 As shown, a storage space is formed inside the closed space in the form of the support seat 21 and the clamping seat 22, which can accommodate pruned branches and trunks, thereby improving subsequent pruning efficiency.

[0026] Further, such as Figure 5 As shown, the clamping assembly 24 includes support rods 241, a second cylinder 242 and a first motor 243. The support rods 241 of the three groups of clamping assemblies 24 are equidistantly fixed on the support base 21 and the clamping base 22, wherein two groups of support rods 241 are fixedly connected to the support base 21, and one group of support rods 241 is fixedly connected to the clamping base 22; Cylinder 242 includes a fixed end and an output end. The output end of cylinder 242 is hinged to support rod 241. A through groove is provided on support rod 241, and a 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. Slide 244 is hinged to connecting rod 1 245. The other end of connecting rod 1 245 is hinged to connecting seat 247. Two groups 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. A crawler 248 is provided on connecting seat 247. Motor 1 243 is fixed to the side of connecting seat 247. The output end of motor 1 243 is connected to crawler 248 for transmission. The transmission connection is located inside connecting seat 247. The transmission connection method can adopt gear transmission connection, or it can be other connection method that drives crawler 248 to rotate on connecting seat 247.

[0027] In actual operation, cylinder 242 extends, driving the slide 244 to move upward in the through groove, causing the connecting rod 1 245 to rotate counterclockwise around the hinge with the slide 244, and at the same time causing the connecting rod 246 to rotate clockwise around the hinge with the support rod 241, moving the connecting seat 247 to the side away from the support rod 241, and providing support for the connecting seat 247, so that the track 248 on the connecting seat 247 fits the branches and trunks to be pruned, and clamps the branches and trunks; then the motor 1 243 is started, driving the track 248 to rotate on the connecting seat 247, and can adjust the clamping position of the branches and trunks when the clamping mechanism 2 moves as a whole without affecting the clamped branches and trunks.

[0028] Supplementary explanation of the above structure: When the clamping mechanism 2 is in a vertical state, the lifting vehicle 11 is controlled to rise, driving the clamping mechanism 2 to move upward. At this time, the branches and trunks tend to move downward relative to the clamping mechanism 2. At the same time, the motor 1 243 is controlled to start forward rotation, driving the crawler 248 to rotate clockwise and counterclockwise on the connecting seat 247. At this time, the crawler 248 can move upward on the branches and trunks while clamping the branches and trunks, so that the position of the clamping assembly 24 clamping the branches and trunks moves upward; conversely, when the clamping mechanism is in a vertical state, the branches and trunks tend to move downward relative to the clamping mechanism 2. When the structure 2 is in a vertical state, the lifting vehicle 11 is controlled to descend, driving the clamping mechanism 2 to move downward. At this time, the branches and trunks tend to move upward relative to the clamping mechanism 2. At the same time, the motor 1 243 is controlled to start reversing, so that the position of the clamping assembly 24 clamping the branches and trunks can be moved downward. Similarly, when the clamping mechanism 2 is in a horizontal state, the lifting vehicle 11 is controlled to move away from the hinge of the support seat 21 and the lifting vehicle 11. At this time, the branches and trunks tend to move closer to the hinge of the support seat 21 and the lifting vehicle 11 relative to the clamping mechanism 2. At the same time, the motor 1 243 is controlled to start forward rotation, driving the crawler 248 to rotate counterclockwise on the connecting seat 247. At this time, while clamping the branches and trunks, the crawler 248 can move on the branches and trunks to the side away from the hinge of the support seat 21 and the lifting vehicle 11, so that the position of the clamping assembly 24 clamping the branches and trunks moves away from the hinge of 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 of the support seat 21 and the lifting vehicle 11. When the joint moves, the branches and trunks tend to move closer to the hinge of the support seat 21 and the lifting vehicle 11 relative to the clamping mechanism 2. At the same time, the control motor 243 starts to rotate forward, which can make the position of the branches and trunks clamped by the clamping assembly 24 move closer to the hinge of the support seat 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 on the basis of maintaining the clamping mechanism 2 on the branches and trunks.

[0029] Specifically, such as Figure 3 、 Figure 6-Figure 8 As shown, the maintenance mechanism 3 includes a connecting plate 31, a rotating assembly 32, a protective shell 33, two groups of paint assemblies 34 and two groups of suction ports 35. The connecting plate 31 is fixed to the end of the support seat 21, the rotating assembly 32 is arranged on the connecting plate 31, the protective shell 33 is arranged on the rotating assembly 32, the two groups of paint assemblies 34 and the two groups of suction ports 35 are all arranged on the protective shell 33, the connecting plate 31 is used to provide support, the rotating assembly 32 is used to drive the protective shell 33 and the paint assembly 34 and the suction port 35 on the protective shell 33 to rotate synchronously, the paint assembly 34 is used to provide auxiliary support and whitewashing for the branches and trunks to be pruned, and the suction port 35 is used to absorb debris generated during pruning.

[0030] Further, such as Figure 6-Figure 8 As shown, the rotating assembly 32 includes a second motor 321, an annular base 322, a rotating turntable 323, a rotating shaft 324 and an extension plate 325. The second motor 321 is fixed to the side of the connecting plate 31 close to 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 through pulleys. The annular base 322 is fixed to the side of the connecting plate 31 away from the second motor 321. The rotating turntable 323 is set on the annular base 322 and is slidably connected to the annular base 322. The two sets of rotating shafts 324 and the rotating turntable 323 are connected by gears. The extension plate 325 is fixed to the side of the rotating turntable 323 away from the connecting plate 31, and the extension plate 325 corresponds to the position of the motor 2 321. The annular base 322 and the rotating turntable 323 are both arc-shaped. The motor 2 321 starts to rotate clockwise, and drives the two sets of rotating shafts 324 to rotate clockwise through the pulley transmission, and then drives the rotating turntable 323 to rotate counterclockwise on the annular base 322 through the gear transmission. Conversely, starting the motor 2 321 to rotate counterclockwise can drive the rotating turntable 323 to rotate clockwise on the annular base 322.

[0031] Further, such as Figure 6-Figure 8 As shown, the protective shell 33 is arc-shaped, and the protective shell 33 matches the shape of the rotating turntable 323. The protective shell 33 is fixed to the side of the rotating turntable 323 away from the support base 21. The side of the protective shell 33 close to the extension plate 325 is provided with a limiting groove 1 331, and the side of the protective shell 33 away from the connecting plate 31 is provided with two sets of limiting grooves 2 332. The protective shell 33 is used to prevent debris from splashing when pruning branches and trunks and to receive pruned branches and trunks. Two groups of suction ports 35 are arranged on both sides of the protective shell 33. Each group of suction ports 35 is provided with several suction ports 35. Several suction ports 35 are connected to the waste box 16 through pipelines. The waste box 16 is connected to a vacuum pump through a pipeline. When the vacuum pump is started, it can absorb the debris generated when pruning branches and trunks, and the waste box 16 will cache it.

[0032] Further, such as Figure 6-Figure 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 arranged on the end of the connecting frame 341 located inside the protective shell 33. The two ends of the torsion spring 344 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. A plurality of 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 arranged on the discharge pipe 342. It is connected to the bearing of the discharge pipe 342, and the shape and position of the discharge pipe 342 match when the limit groove 332 and the connecting frame 341 rotate. The discharge pipe 342 is connected to the liquid storage tank 15 through a pipeline. A liquid pump and a hydraulic sensor are provided on the connecting pipeline between the discharge pipe 342 and the liquid storage tank 15. The hydraulic sensor and the liquid pump are electrically connected to the remote control end. The hydraulic sensor is provided 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 liquid 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, and then control the intelligent start and stop of the liquid pump.

[0033] 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 toward the inside of the protective shell 33 toward the side close to the suction port 35, further ensuring that the discharge pipe 342 on the coating assembly 34 can fit the pruned branches and trunks; after the pruning is completed, the control cylinder 1 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 be restored to the initial state under the elastic force of the torsion spring 344, and 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 supporting role for the pruned branches and trunks, the branches and trunks assisted by the two groups of discharge pipes 342 can bounce up under the elastic force of the torsion spring 344, making it convenient for the staff to take out the pruned branches and trunks; The liquid inside the discharge pipe 342 can flow out from the discharge port 3421 to soak the roller brush 343, but since the discharge port 3421 is set 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 soaked at the discharge port 3421, and the liquid inside the discharge pipe 342 cannot flow out from the discharge port 3421, resulting in an increase in the hydraulic pressure on the pipeline between the discharge pipe 342 and the output end of the liquid pump. When the hydraulic pressure detected by the hydraulic sensor reaches a certain value, the specific hydraulic value is set by the staff and fed back to the remote control end, and the remote control end controls the liquid pump to stop running; when the rotating component 32 drives the rotating turntable 323 to drive the protective shell 33 to rotate, since the roller brush 343 contacts the branches and trunks, and the surface of the branches and trunks The roughness will cause friction, and since the connecting frame 341 is connected to the protective shell 33 by the torsion spring 344, when the protective shell 33 rotates, the friction between the roller brush 343 and the branches and trunks can make the connecting frame 341 rotate around the rotating connection with the protective shell 33, changing the radial clamping position of the roller brush 343 on the branches and trunks and the contact position of the roller brush 343 on the branches and trunks, so that the liquid inside the discharge pipe 342 can again soak the extrusion part 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 it is reduced to a certain value, the specific hydraulic pressure value is set by the staff and fed back to the remote control end, which controls the start of the liquid pump to pump the liquid inside the liquid storage tank 15 into the discharge pipe 342, thereby realizing the intelligent start and stop of the liquid pump and the brushing of the branches and trunks in the circumferential direction.

[0034] Specifically, such as Figure 8 As shown, the pruning mechanism 4 includes a movable seat 41, a rotating platform 42 and an electric saw 43. The movable seat 41 is fixed to the side of the extension plate 325 away from the connecting plate 31, the rotating platform 42 is fixed to the side of the movable seat 41 away from the connecting plate 31, and the electric saw 43 is fixed to the side of the rotating platform 42 away from the connecting plate 31. The movable seat 41 is used to drive the electric saw 43 to move along the setting direction of the movable seat 41. The electric saw 43 corresponds to the position of the limiting groove 331. The movable seat 41 can be a movable seat driven by a motor and a screw rod. The rotating platform 42 is used to drive the electric saw 43 to rotate, thereby adjusting the pruning direction of the electric saw 43. The rotating platform 42 can be a rotating seat driven by a motor and a pulley. The electric saw 43 is used to prune branches and trunks.

[0035] Supplementary explanation of the above structure: the staff controls the electric saw 43 to start through the remote control terminal, controls the movable seat 41 to start and move toward the arc-shaped opening of the protective shell 33, and controls the rotating table 42 to start and drive the electric saw 43 to rotate, so that the electric saw 43 can prune the branches and trunks. If necessary, the motor 2 321 can also be controlled to start, driving the pruning mechanism 4 to adjust the pruning position as a whole. The electric saw 43 is driven by the rotating table 42 to move toward the arc-shaped opening of the protective shell 33 and the rotating table 42 drives the electric saw 43 to rotate, which can adapt to the pruning of branches and trunks with different diameters.

[0036] When the clamping mechanism 2 clamps the branches and trunks and the coating component 34 provides auxiliary support for the branches and trunks, the coating component 34 rotates toward the side of the protective shell 33 close to the suction port 35, so that a relatively closed space can be formed at the trimming location of the branches and trunks, with only the limiting groove 331 and the two ends of the protective shell 33 being in an open state. At this time, the vacuum fan is started, and the debris generated by pruning can be adsorbed into the waste box 16 through the suction port 35 for buffering. By setting the coating component 34 and the protective shell 33, the debris generated by pruning can be further prevented from flying.

[0037] When the clamping mechanism 2 tends to be horizontal, if the clamping mechanism 2 is in a closed state, it can clamp the branches and trunks to be pruned and fallen, which is suitable for pruning thick branches; if the clamping mechanism 2 is in an open state, it can catch the pruned branches and trunks, which is suitable for pruning small branches and trunks, and thus can prevent 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 to remove the pruned branches and trunks, thereby avoiding the branches and trunks falling directly during pruning and causing injuries to the staff.

[0038] When the clamping mechanism 2 tends to be in a vertical state, the clamping mechanism 2 clamps the branches and trunks, and then controls the motor 2 321 to start, drives the rotary turntable 323 to rotate, controls the lifting vehicle 11 to lift, starts the motor 1 243 to drive the crawler 248 to rotate, and starts the liquid pump, so that the liquid inside the liquid storage tank 15 can be brushed onto the surface of the branches and trunks, which is suitable for whitewashing the branches and trunks of tall trees and applying insect repellents; if the motor 2 321 is controlled to start, drives the rotary turntable 323 to rotate, controls the lifting vehicle 11 to lift, starts the motor 1 243 to drive the crawler 248 to rotate, and starts the vacuum pump, the surface of the branches and trunks can be cleaned, and the generated debris can be adsorbed and recovered, so as to avoid the branches and trunks from being infected with diseases and insect pests due to the long-term presence of dead bark and debris on the surface of the branches and trunks, and is suitable for cleaning the surface of the branches and trunks.

[0039] 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 close to the hinge with the lifting vehicle 11 and the end away from the hinge with the lifting vehicle 11 according to actual needs, thereby being able to meet various usage needs; in actual use, including but not limited to the usage described above.

[0040] Through the above method, high-altitude branches in landscaping can be pruned, and branches and trunks in the pruning process can be clamped and flying debris generated can be adsorbed to avoid flying debris and fallen branches during pruning to cause harm to workers. At the same time, trees can be whitewashed when necessary to reduce the labor intensity of workers, thereby improving the efficiency and safety of pruning high-altitude branches and trunks in landscaping.
