Description

Technical Field

[0001] This invention relates to the field of garden pruning technology, specifically a garden landscape pruning device and method. Background Technology

[0002] With the booming development of the tourism industry, landscape design in tourist attractions has become an important means to improve the quality of scenic spots, attract tourists, protect the ecological environment, and promote the sustainable development of the tourism industry. Landscape design requires daily pruning. Pruning can improve wind resistance. Appropriate pruning of trees can correct and repair the shape of the tree, form a good wind-resistant structure, reduce damage to the trunk and bark, and improve public safety. It can also reduce diseases and dead branches. Scientific pruning can improve the lighting and ventilation conditions inside the branches, reduce the occurrence of diseases and pests. Vigorous branches, drooping branches, crossing branches, parallel branches, diseased and insect-infested branches, dead branches, dead and damaged branches, dead leaves (palm family) and flower stalks also need to be pruned in time to promote healthy tree growth and maintain beauty. Pruning requires the use of pruning equipment.

[0003] Chinese patent discloses an automatic pruning device for shrub belts (publication number CN112314216A). This patent includes a housing with a working chamber that extends horizontally and opens downwards. Support bodies are slidably mounted on the front and rear side walls of the working chamber, with the two support bodies symmetrically arranged. An upward-opening motor cavity is located at the upper end of each support body. The left and right side walls of the motor cavity slide against the housing. A motor is fixedly mounted on the lower side wall of the motor cavity. A power shaft is connected to the front end of the rear motor, passing through the front side wall of the motor cavity. This device can automatically prune shrubs and collect the pruned leaves to prevent them from scattering and soiling the road. It can also automatically irrigate, avoiding secondary work, greatly reducing the workload of sanitation workers, saving time, and ensuring work efficiency. However, because the number of pruned branches and leaves is large, it requires a pneumatic vehicle for transportation, which somewhat limits work efficiency. Summary of the Invention

[0014] A method for pruning garden landscapes, comprising the following steps: S1. Based on the terrain of the garden landscape and the location of the trees, the movable frame moves up and down along the outside of the fixed frame by extending and retracting the lifting hydraulic cylinder, adjusting the height of the frame to meet the passability requirements of the garden landscape terrain; then, the power motor drives the drive gear to rotate, and the drive gear meshes with the driven gear to drive the driven gear, support column and connecting block to rotate together. The connecting block drives the movable frame, fixed frame, wheel hub motor and wheels to rotate together, adjusting the angle of the wheels so that the direction of the wheels travels is consistent with the direction of the tree distribution; S2. The drive motor and drive belt drive the rotating shaft and gear to rotate. The gear meshes with the gear ring, so that the gear ring and the sleeve rotate together on the outside of the fixed shaft with the bearing as the center. This drives the rotating L-shaped support rod, the lifting L-shaped support rod and the telescopic rod to rotate together, adjusting the position of the pruning angle adjustment mechanism and the pruning and crushing mechanism, so that the pruning and crushing mechanism faces the position of the tree to be pruned. The telescopic rod and the telescopic power mechanism inside the lifting L-shaped support rod drive the telescopic rod to move horizontally inside the lifting L-shaped support rod, thereby adjusting the position of the pruning and shredding mechanism in the vertical direction; then the telescopic power mechanism inside the lifting L-shaped support rod and the rotating L-shaped support rod drive the lifting L-shaped support rod to move up and down inside the rotating L-shaped support rod, so that the pruning and shredding mechanism is close to the position of the tree being pruned. S3. The motor drives the central shaft and the disc to rotate, which in turn drives the two eccentric discs at the upper and lower ends of the disc to move eccentrically. This causes the upper and lower saw blades to move alternately along the strip fixed plate in the front and back direction, thus pruning the garden trees. At the same time, a negative pressure pump generates negative pressure inside the collection cylinder, sucking the pruned branches and leaves into the collection cylinder. Then, the crushing motor drives the crushing shaft and the crushing blade to rotate at high speed. The crushing blade breaks up the branches and leaves, which are then filtered through the filter screen and sprayed out from the output end of the negative pressure pump. The pruned branches and leaves are used as fertilizer for the growth of the garden trees. S4. The hub motor drives the wheels to rotate, causing them to move along the ground and thus the entire pruning equipment along the direction of tree pruning. Simultaneously, motor one drives the flange to rotate, causing motor one, connecting rod one, connecting rod two, swing rod one, and connecting frame one to rotate together, making the pruning and shredding mechanism rotate in the XY plane of three-dimensional space. Motor two drives connecting rod two, swing rod one, and connecting frame one to rotate together, making the pruning and shredding mechanism rotate in the YZ plane of three-dimensional space. Motor three drives swing rod one and connecting frame one to rotate together, making the pruning and shredding mechanism rotate in the XZ plane of three-dimensional space. This allows the angle of the pruning and shredding mechanism to be adjusted throughout the three-dimensional space, enabling different angles of pruning for the garden landscape and improving the pruning quality.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention prunes garden trees using a pruning component in a pruning and crushing mechanism; simultaneously, a negative pressure pump draws the pruned branches and leaves into a collection cylinder; then, a crushing motor drives the crushing shaft and crushing blades to rotate at high speed, crushing the branches and leaves. After being filtered through a filter screen, the crushed branches and leaves are sprayed out from the output end of the negative pressure pump, using the pruned branches and leaves as fertilizer for the growth of garden trees, without the need to clean up the waste branches and leaves. The rotating arm assembly allows the pruning and shredding mechanism to rotate, and its position can be adjusted in both horizontal and vertical directions, expanding its pruning range. The pruning angle adjustment mechanism allows the angle of the pruning and shredding mechanism to be adjusted in the entire three-dimensional space, thereby enabling the pruning of the garden landscape at different angles.

[0018] Please see Figures 1-11 In this embodiment of the invention, a garden landscape trimming device includes a frame 1 and adjustable driving wheels 3 installed at the four corners of the lower end of the frame 1. A control box 2 is installed on the upper end of the frame 1. A rotating arm assembly 4 that can rotate, lift and extend is embedded in the upper end of the control box 2. A trimming angle adjustment mechanism 5 that can rotate at multiple angles is installed at one end of the rotating arm assembly 4. A trimming and shredding mechanism 6 for trimming and shredding the garden landscape is installed at the lower end of the trimming angle adjustment mechanism 5. like Figure 2 , Figure 3 and Figure 4 As shown, the trimming and shredding mechanism 6 includes a collection cylinder 61 and a trimming assembly 64 installed at the lower end of the collection cylinder 61. A working box 65 is installed at the front end of the collection cylinder 61, and a shredding motor 62 is installed at the rear end of the collection cylinder 61. The output end of the shredding motor 62 is located inside the collection cylinder 61 and a shredding shaft 69 is installed. Several sets of crushing blades 610 are installed on the shredding shaft 69. A feed inlet 63 is opened on one side of the collection cylinder 61 near the upper end of the trimming assembly 64, and a negative pressure pump 68 is connected to the upper end of the collection cylinder 61 through a flared mouth 67. A filter screen 611 is provided at the junction of the collection cylinder 61 and the flared mouth 67. A connecting frame 66 is fixedly connected to the front side of the upper end of the collection cylinder 61 near the flared mouth 67. The pruning assembly 64 prunes the garden trees; at the same time, the negative pressure pump 68 generates negative pressure inside the collection cylinder 61, sucking the pruned branches and leaves into the collection cylinder 61; then the pulverizing motor 62 drives the pulverizing shaft 69 and the crushing blade 610 to rotate at high speed, crushing the branches and leaves through the crushing blade 610. After being filtered by the filter screen 611, the crushed branches and leaves are sprayed out from the output end of the negative pressure pump 68, using the pruned branches and leaves as fertilizer for the growth of the garden trees; without the need to clean up the waste branches and leaves.

[0019] like Figure 4 and Figure 5 As shown, the trimming assembly 64 includes an upper saw blade 641 and a lower saw blade 642 located below the upper saw blade 641. A strip-shaped fixing plate 643 is provided at the lower end of the lower saw blade 642. Several strip-shaped guide holes 652 are provided on the inner sides of both the upper saw blade 641 and the lower saw blade 642. A limiting post 650 is fixedly connected to the upper end of the strip-shaped fixing plate 643 within each strip-shaped guide hole 652. When the upper saw blade 641 and the lower saw blade 642 move relative to each other, the strip-shaped guide holes 652 slide along the outer side of the limiting post 650, thereby ensuring that the upper saw blade 641 and the lower saw blade 642 can slide stably. A disc 646 is provided inside the work box 65. A central shaft 644 is provided through the center of the disc 646. An eccentric disc 647 is fixedly connected to both the upper and lower ends of the disc 646. A shaft head 651 is fixedly connected to the front side of the upper end of 641 and the front side of the lower end of the lower saw blade 642. A swing arm 649 is rotatably connected between the shaft head 651 and the corresponding eccentric disk 647. A motor 645 is fixedly connected to the lower end of the central shaft 644, and a bearing seat 648 containing a bearing is installed at the upper end of the central shaft 644. The bearing seat 648 is installed at the upper end of the inside of the working box 65, and the motor 645 is fixedly installed at the lower end of the outside of the working box 65. The upper saw blade 641, the lower saw blade 642 and the strip fixing plate 643 pass through the inside of the working box 65. The front end of the strip fixing plate 643 is fixedly connected to the working box 65, and the rear end of the strip fixing plate 643 is fixedly connected to the rear end of the collecting cylinder 61. The upper saw blade 641 and the lower saw blade 642 are slidably connected to the collecting cylinder 61. The motor 645 drives the central shaft 644 and the disc 646 to rotate, thereby causing the two eccentric discs 647 at the upper and lower ends of the disc 646 to move eccentrically. When one eccentric disc 647 pulls the corresponding swing arm 649 backward, the other eccentric disc 647 pushes the corresponding swing arm 649 forward, so that the upper saw blade 641 and the lower saw blade 642 move alternately in the front and back direction along the strip fixed plate 643. The upper saw blade 641 and the lower saw blade 642 can be used to prune garden trees.

[0020] like Figure 6 and Figure 7As shown, the rotating arm assembly 4 includes a rotating L-shaped support rod 41 and a lifting L-shaped support rod 42 that is slidably embedded in the upper end of the rotating L-shaped support rod 41. A telescopic rod 43 is embedded in one end of the lifting L-shaped support rod 42. A sleeve 45 is fixedly connected to the lower end of the rotating L-shaped support rod 41. A gear ring 44 is embedded in the inner side of the lower end of the sleeve 45. A fixed shaft 410 is connected to the inner side of the gear ring 44 through a bearing 411. A gear 46 is meshed with the outer side of the gear ring 44. A rotating shaft 49 is fixedly connected to the lower end of the gear 46. A drive motor 47 is connected to the rotating shaft 49 through a drive belt 48. The sleeve 45 passes through the upper end of the control box 2. The gear ring 44, fixed shaft 410, gear 46, rotating shaft 49, drive belt 48, and drive motor 47 are all installed inside the control box 2. The lower end of the fixed shaft 410 is fixedly installed inside the lower end of the control box 2. The rotating shaft 49 is rotatably installed inside the lower end of the control box 2 through a bearing. The drive motor 47 drives the rotating shaft 49 to rotate around the corresponding bearing via the drive belt 48, thereby causing the gear 46 to rotate. The gear 46 meshes with the gear ring 44, causing the gear ring 44 and the sleeve 45 to rotate together on the outside of the fixed shaft 410 around the bearing 411. This, in turn, drives the rotating L-shaped support rod 41, the lifting L-shaped support rod 42, and the telescopic rod 43 to rotate together. The telescopic rod 43 drives the trimming angle adjustment mechanism 5 and the trimming and shredding mechanism 6 to rotate together, thus expanding the trimming range of the trimming and shredding mechanism 6.

[0021] like Figure 6 and Figure 8 As shown, telescopic power mechanisms are installed inside the telescopic rod 43 and the lifting L-shaped support rod 42, as well as inside the lifting L-shaped support rod 42 and the rotating L-shaped support rod 41. Each telescopic power mechanism includes a lead screw motor 412, the output end of which is fixedly connected to a ball screw 414, and a nut pair 413 is engaged with the ball screw 414. In the telescopic power mechanism located at the junction of the telescopic rod 43 and the lifting L-shaped support rod 42, a through groove is provided at the lower part of the telescopic rod 43, the screw motor 412 is fixed inside the lifting L-shaped support rod 42, and the nut pair 413 is fixedly connected to the telescopic rod 43. When the screw motor 412 drives the ball screw 414 to rotate, the nut pair 413 moves horizontally along the ball screw 414, thereby driving the telescopic rod 43 to move horizontally inside the lifting L-shaped support rod 42 through the nut pair 413, thereby adjusting the position of the trimming and crushing mechanism 6 in the lateral direction. Similarly, in the telescopic power mechanism located at the junction of the lifting L-shaped support rod 42 and the rotating L-shaped support rod 41, a through groove is provided on one side of the lifting L-shaped support rod 42, the screw motor 412 is fixed inside the rotating L-shaped support rod 41, and the nut pair 413 is fixedly connected to the lifting L-shaped support rod 42. When the screw motor 412 drives the ball screw 414 to rotate, the nut pair 413 moves horizontally along the ball screw 414, thereby driving the lifting L-shaped support rod 42 to move up and down inside the rotating L-shaped support rod 41 through the nut pair 413, thereby adjusting the position of the trimming and crushing mechanism 6 in the vertical direction.

[0022] like Figure 9 and Figure 10 As shown, the adjustable walking wheel 3 includes a wheel 31. A hub motor 32 is installed at one end of the wheel 31. A fixed frame 34 is fixedly connected to the upper outer side of the hub motor 32. A movable frame 35 is slidably connected to the upper outer side of the fixed frame 34. A set of lifting hydraulic cylinders 33 is installed inside both the fixed frame 34 and the movable frame 35. A connecting block 36 is fixedly connected to the upper end of the movable frame 35. A power box 37 is provided at the upper end of the connecting block 36. The hub motor 32 drives the wheel 31 to rotate, and the wheel 31 moves on the ground, which can move the entire trimming equipment. By extending and retracting the lifting hydraulic cylinder 33, the movable frame 35 can move up and down along the outer side of the fixed frame 34, thereby adjusting the height of the frame 1 to improve the passability of the trimming equipment. The power box 37 is equipped with a power supply. The output end of motor 38 is fixedly connected to drive gear 39. Drive gear 310 is meshed with the inner side of drive gear 39. Support column 311 is fixedly connected to the lower end of driven gear 310. Support column 311 is rotatably connected to power box 37, and the lower end of support column 311 is fixedly connected to the upper end of connecting block 36. The upper end of power box 37 is fixedly connected to frame 1. Drive gear 39 is driven to rotate by motor 38. Drive gear 39 meshes with driven gear 310, thereby driving driven gear 310, support column 311 and connecting block 36 to rotate together. Connecting block 36 drives movable frame 35, fixed frame 34, hub motor 32 and wheel 31 to rotate together, thereby adjusting the angle of wheel 31 and driving the entire trimming equipment to move in different directions.

[0023] like Figure 6 and Figure 11 As shown, the trimming angle adjustment mechanism 5 includes a bending connecting rod 51, a motor 52 is installed on the lower side of the upper end of the bending connecting rod 51, a flange 53 is fixedly connected to the output end of the motor 52, the lower end of the bending connecting rod 51 is connected to a bending connecting rod 55 via a motor 54, the front end of the bending connecting rod 55 is connected to a swing rod 57 via a motor 56, and a connecting frame 58 is fixedly connected to the lower end of the swing rod 57. Connecting bracket 58 is fixedly connected to connecting bracket 66, thereby fixing the trimming angle adjustment mechanism 5 and the trimming and crushing mechanism 6 together; flange 53 is fixedly connected to telescopic rod 43, thereby fixing the rotating arm assembly 4 and the trimming angle adjustment mechanism 5 together. Motor 52 drives flange 53 to rotate. Since flange 53 is fixed on telescopic rod 43, motor 52, connecting rod 51, connecting rod 55, swing rod 57, and connecting frame 58 rotate together, allowing the pruning and shredding mechanism 6 to rotate in the XY plane of three-dimensional space. Motor 54 drives connecting rod 55, swing rod 57, and connecting frame 58 to rotate together, allowing the pruning and shredding mechanism 6 to rotate in the YZ plane of three-dimensional space. Motor 56 drives swing rod 57 and connecting frame 58 to rotate together, allowing the pruning and shredding mechanism 6 to rotate in the XZ plane of three-dimensional space. Thus, the angle of the pruning and shredding mechanism 6 can be adjusted throughout the three-dimensional space, allowing the pruning and shredding mechanism 6 to prune the garden landscape at different angles.

[0024] A method for pruning garden landscapes, comprising the following steps: S1. Based on the terrain of the garden landscape and the location of the trees, the movable frame 35 moves up and down along the outside of the fixed frame 34 by extending and retracting the lifting hydraulic cylinder 33, adjusting the height of the frame 1 to meet the requirements of the garden landscape terrain for passability; then the power motor 38 drives the drive gear 39 to rotate, and the drive gear 39 meshes with the driven gear 310 to drive the driven gear 310, the support column 311 and the connecting block 36 to rotate together. The connecting block 36 drives the movable frame 35, the fixed frame 34, the hub motor 32 and the wheel 31 to rotate together, adjusting the angle of the wheel 31 so that the direction of travel of the wheel 31 is consistent with the direction of tree distribution; S2. The drive motor 47 and drive belt 48 drive the rotating shaft 49 and gear 46 to rotate. The gear 46 meshes with the gear ring 44, causing the gear ring 44 and sleeve 45 to rotate together on the outside of the fixed shaft 410 with the bearing 411 as the center. This drives the rotating L-shaped support rod 41, the lifting L-shaped support rod 42 and the telescopic rod 43 to rotate together, adjusting the position of the pruning angle adjustment mechanism 5 and the pruning shredding mechanism 6 so that the pruning shredding mechanism 6 faces the position of the tree being pruned. The telescopic rod 43 is driven to move horizontally inside the lifting L-shaped support rod 42 by the telescopic power mechanism inside the telescopic rod 43 and the lifting L-shaped support rod 42, thereby adjusting the position of the pruning and shredding mechanism 6 in the vertical direction; then the telescopic power mechanism inside the lifting L-shaped support rod 42 and the rotating L-shaped support rod 41 drives the lifting L-shaped support rod 42 to move up and down inside the rotating L-shaped support rod 41, so that the pruning and shredding mechanism 6 is close to the position of the pruned tree. S3. The motor 645 drives the central shaft 644 and the disc 646 to rotate, thereby causing the two eccentric discs 647 at the upper and lower ends of the disc 646 to move eccentrically. This causes the upper saw blade 641 and the lower saw blade 642 to move alternately along the strip fixed plate 643 in the front-back direction. The upper saw blade 641 and the lower saw blade 642 can prune the garden trees. At the same time, the negative pressure pump 68 generates negative pressure inside the collection cylinder 61, which sucks the pruned branches and leaves into the collection cylinder 61. Then, the crushing motor 62 drives the crushing shaft 69 and the crushing blade 610 to rotate at high speed. The crushing blade 610 crushes the branches and leaves. After being filtered by the filter screen 611, the crushed branches and leaves are sprayed out from the output end of the negative pressure pump 68, and the pruned branches and leaves are used as fertilizer for the growth of garden trees. S4. The hub motor 32 drives the wheel 31 to rotate, and the wheel 31 moves on the ground, causing the entire pruning equipment to move along the direction of tree pruning. At the same time, the motor 1 52 drives the flange 53 to rotate, causing the motor 1 52, the connecting rod 1 51, the connecting rod 2 55, the swing rod 1 57, and the connecting frame 1 58 to rotate together, causing the pruning and shredding mechanism 6 to rotate in the XY plane of three-dimensional space. The motor 2 54 drives the connecting rod 2 55, the swing rod 1 57, and the connecting frame 1 58 to rotate together, causing the pruning and shredding mechanism 6 to rotate in the YZ plane of three-dimensional space.

S2. The drive motor (47) and drive belt (48) drive the rotating shaft (49) and gear (46) to rotate. The gear (46) meshes with the gear ring (44) to drive the gear ring (44) and sleeve (45) to rotate together on the outside of the fixed shaft (410) with the bearing (411) as the center. This drives the rotating L-shaped support rod (41), the lifting L-shaped support rod (42) and the telescopic rod (43) to rotate together, adjusting the position of the pruning angle adjustment mechanism (5) and the pruning shredding mechanism (6) so that the pruning shredding mechanism (6) faces the position of the tree being pruned. The telescopic rod (43) and the telescopic power mechanism inside the lifting L-shaped support rod (42) drive the telescopic rod (43) to move horizontally inside the lifting L-shaped support rod (42), thereby adjusting the position of the pruning and shredding mechanism (6) in the vertical direction; then the telescopic power mechanism inside the lifting L-shaped support rod (42) and the rotating L-shaped support rod (41) drives the lifting L-shaped support rod (42) to move up and down inside the rotating L-shaped support rod (41), so that the pruning and shredding mechanism (6) is close to the position of the pruned tree; S3. The central shaft (644) and the disc (646) are rotated by the motor (645), which in turn drives the two eccentric discs (647) at the upper and lower ends of the disc (646) to move eccentrically, so that the upper saw blade (641) and the lower saw blade (642) move alternately in the front and back direction along the strip fixed plate (643). The upper saw blade (641) and the lower saw blade (642) can be used to prune the garden landscape trees. At the same time, the negative pressure pump (68) generates negative pressure inside the collection cylinder (61) to suck the pruned branches and leaves into the collection cylinder (61). Then, the crushing motor (62) drives the crushing shaft (69) and the crushing blade (610) to rotate at high speed. The crushing blade (610) crushes the branches and leaves. After being filtered by the filter screen (611), the crushed branches and leaves are sprayed out from the output end of the negative pressure pump (68) and the pruned branches and leaves are used as fertilizer for the growth of garden landscape trees. S4. The wheel (31) is driven to rotate by the hub motor (32), and the wheel (31) moves on the ground, so that the entire pruning equipment moves along the direction of the tree being pruned; at the same time, the flange (53) is driven to rotate by the first motor (52), so that the first motor (52), the first bent connecting rod (51), the second bent connecting rod (55), the first swing rod (57) and the first connecting frame (58) rotate together, so that the pruning and shredding mechanism (6) rotates in the XY plane of three-dimensional space; the second motor (54) drives the second bent connecting rod (55), the first swing rod (57) and the first connecting frame (58) to rotate together, so that the pruning and shredding mechanism (6) rotates in the YZ plane of three-dimensional space; the third motor (56) drives the first swing rod (57) and the first connecting frame (58) to rotate together, so that the pruning and shredding mechanism (6) rotates in the XZ plane of three-dimensional space; thus, the angle of the pruning and shredding mechanism (6) can be adjusted in the entire three-dimensional space, and the garden landscape can be pruned at different angles by the pruning and shredding mechanism (6), thereby improving the pruning quality.
