Description

Technical Field

[0001] This invention relates to the field of landscaping technology, specifically a garden leaf trimming device with angle adjustment function. Background Technology

[0002] A garden foliage trimming device is a device used by staff to regularly trim the leaves of garden trees in order to ensure their aesthetic appeal and survival rate.

[0003] Traditional leaf trimming devices typically only trim the top or sides of trees, affecting efficiency. Furthermore, different trees have varying top and side lengths, and traditional devices cannot adjust the trimming length accordingly. When the trimming length exceeds the device's length, a second trimming is required, further reducing efficiency. Additionally, after trimming, the cut leaves and branches fall to the ground, requiring manual cleanup and increasing labor costs. Moreover, the blades of traditional devices are usually horizontally positioned, making it impossible to adjust their angle. This causes the blades to slip on irregular branches, deviating from the intended trimming direction and affecting the final result. Summary of the Invention

[0004] The purpose of this invention is to provide a garden leaf trimming device with angle adjustment function to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A garden leaf trimming device with angle adjustment function includes a base, a robotic arm, a trimming mechanism, a retrieval mechanism, and an angle adjustment mechanism. The base and the robotic arm are fixedly connected. There are three angle adjustment mechanisms. The robotic arm and one angle adjustment mechanism are fixedly connected. There are three trimming mechanisms. The three trimming mechanisms are fixedly connected to the three angle adjustment mechanisms respectively. The retrieval mechanism is fixedly connected to the base and the retrieval mechanism is fixedly connected to the trimming mechanisms.

[0006] The robotic arm is mounted on a base, which can be installed on a trolley or other moving mechanism, allowing it to move the trimming device and automatically trim garden leaves. The moving end of the robotic arm is fixed to an angle adjustment mechanism, which is also fixed to a trimming mechanism. The trimming mechanism is fixed to two other angle adjustment mechanisms on both sides, and these other two angle adjustment mechanisms are fixed to the trimming mechanism and the other two trimming mechanisms. This allows the other two trimming mechanisms to be located on both sides of the top trimming mechanism, enabling simultaneous trimming of the top and sides of the tree. The angle adjustment mechanism adjusts the tilt angle of the trimming mechanism to make the trimming part as perpendicular as possible to the branch to be trimmed, reducing vibration of the trimming part caused by the reaction force of the branch during trimming. It also prevents the branch from twisting when the trimming part comes into contact with the branch, which could cause the blade to slip and affect the trimming effect. A recycling mechanism generates negative pressure to suck the trimmed branches and leaves into a storage box.

[0007] Furthermore, the cutting mechanism includes a mounting frame, a drive unit, a chain, cutting tools, a length adjustment unit, and a fixing plate. The mounting frame is fixedly connected to the angle adjustment mechanism, the drive unit is fixedly connected to the mounting frame, the drive unit is connected to the chain drive, and there are several cutting tools. The cutting tools are fixedly connected to the chain, the length adjustment unit is slidably connected to the cutting tools, and there are two fixing plates. Two fixing plates are fixedly connected to the angle adjustment mechanism, one fixing plate is fixedly connected to the mounting frame, and the other fixing plate is fixedly connected to the length adjustment unit.

[0008] The cutting tools are fixed by a mounting bracket and an angle adjustment mechanism, allowing the angle adjustment mechanism to adjust the angle of the cutting tools. A drive unit fixed to the mounting bracket is connected to a chain drive, causing the drive unit to drive the chain to rotate at high speed. This causes several cutting tools on the chain to move at high speed with the chain, thus allowing the cutting tools to cut the branches. A length adjustment unit is slidably connected to the cutting tools, guiding the chain so that the chain's trajectory is U-shaped. The length adjustment unit drives the chain to move, making the groove smaller and the U-shaped distribution of the chain on one side longer, thereby adjusting the cutting length. Two fixing plates are installed on the mounting bracket and the length adjustment unit respectively. These two fixing plates are fixed to two other angle adjustment mechanisms, allowing two other cutting mechanisms to be installed on both sides of the top cutting mechanism.

[0009] Furthermore, the length adjustment unit includes a mounting plate, a connecting shaft, a guide post, a connecting plate, and a cylinder. The mounting plate and the mounting bracket are slidably connected. There are two connecting shafts, which are rotatably connected to the mounting plate. One connecting shaft is fixedly connected to the drive unit, and the other connecting shaft is fixedly connected to the guide post. The mounting bracket has two sliding grooves, and the two connecting shafts are slidably connected to the two sliding grooves respectively. The connecting plate and the mounting plate are fixedly connected. The cylinder and the mounting bracket are fixedly connected, and the cylinder output end is fixedly connected to the connecting plate.

[0010] Two connecting shafts are installed on the mounting plate. One connecting shaft is fixed to the drive unit, and the other connecting shaft is fixed to the guide post, so that the chain track is U-shaped. The guide post is located on the concave side of the chain, and the drive unit connected to the connecting shaft is located on the protruding position on one side. A connecting plate is fixed on the mounting plate, and a cylinder is fixed on the mounting frame. The output end of the cylinder is fixed to the connecting plate, so that the cylinder can drive the mounting plate to move. The connecting shaft is slidably connected to two sliding grooves respectively, so that the mounting plate slides along the sliding grooves, thereby adjusting the cutting length.

[0011] Furthermore, the cutting tool includes a fixed frame and a blade, a guide post with a limiting groove and a storage groove, a fixed frame and a blade, a fixed frame and a chain, and a slidable connection between the limiting groove and the fixed frame.

[0012] The blade is welded to a fixed frame welded onto the chain, allowing the blade to move with the chain and thus prune the tree. A storage groove is provided on the guide post to prevent the blade from contacting the guide post. A limiting groove is provided on the guide post, and the limiting groove and the fixed frame are slidably connected to prevent the chain from slipping off the guide post.

[0013] Furthermore, the drive unit includes a drive motor, drive shafts, and sprockets. The drive motor and the mounting bracket are fixedly connected. There are three drive shafts and four sprockets. The output end of the drive motor is fixedly connected to one drive shaft. The three drive shafts are rotatably connected to the mounting bracket. The four sprockets cooperate with the chain. The three drive shafts and the three sprockets are fixedly connected. A connecting shaft and another sprocket are fixedly connected.

[0014] The drive motor is fixed on the mounting bracket. The sprockets and chain work together. The chain is fitted onto four sprockets and guide posts, so that the track of the chain is U-shaped. The output end of the drive motor is fixed to a drive shaft, so that the drive motor can drive the connected drive shaft to rotate. The sprockets are mounted on the drive shaft, so that the sprockets rotate with the drive shaft, thereby driving the chain to rotate.

[0015] Furthermore, the angle adjustment mechanism includes a detection unit, a connecting block, a rotating shaft, a connecting seat, and a rotating motor. The detection unit is fixedly connected to the mounting bracket, the connecting block is rotatably connected to the rotating shaft, the connecting seat is fixedly connected to the rotating shaft, the rotating motor is fixedly connected to the connecting block, and the output end of the rotating motor is fixedly connected to the rotating shaft.

[0016] The angle between the branch and the blade is detected by the detection unit set on the mounting frame. The connecting seat is fixedly installed on the mounting frame, and the two ends of the rotating shaft are fixedly connected to the connecting seat. The connecting block is rotatably connected to the rotating shaft. The rotating motor is fixedly installed on the connecting block through the base. The output end of the rotating motor is fixed to the rotating shaft, so that the rotating motor can drive the rotating shaft to rotate, thereby causing the connecting seat to drive the mounting frame to rotate, thus changing the blade's tilt angle.

[0017] Furthermore, the detection unit includes a sliding block, a rotating plate, a support shaft, and an angle sensor. There are two support shafts, which are fixedly connected to the rotating plate and rotatably connected to the two sliding blocks respectively. The angle sensor is fixedly connected to the sliding block, and the detection end of the angle sensor is fixedly connected to one support shaft.

[0018] The rotating plate is supported by support shafts fixed on both sides, and the sliding blocks on both sides are rotatably connected to the support shafts, thus supporting the rotating plate at both ends. The initial position of the rotating plate is above the chain and the blade, and in front of the cutting direction, so that the rotating plate can contact the branch before the blade. The rotating plate fits against the branch and rotates. An angle sensor fixed on the sliding block and whose detection end is fixed on the support shaft can detect the angle of rotation of the support shaft, and thus detect the angle between the branch and the blade.

[0019] Furthermore, the detection unit also includes a reset spring, the mounting bracket is provided with two guide grooves, there are two reset springs, the two reset springs are respectively placed in the two guide grooves, two sliding blocks are respectively fixedly connected to the two reset springs, and the two sliding blocks are respectively slidably connected to the two guide grooves.

[0020] The mounting bracket has two guide slots, each containing a return spring. The return springs and sliding blocks are fixed in place. After the rotating plate contacts the branch, the mounting bracket continues to move. Under the reaction force of the branch, the rotating plate pushes the sliding block to overcome the elastic force of the return spring and slide into the guide slot, thus preventing the rotating plate from affecting the cutting of the branch by the blade.

[0021] Furthermore, the recycling mechanism includes a high-pressure blower, a collection box, a baffle, a top air guide hood, and a bottom air guide hood. The high-pressure blower and the collection box are fixedly connected. The collection box has a storage slot. The baffle is placed in the storage slot. The suction end of the high-pressure blower is connected to the storage slot by a pipe. The storage slot is connected to the top air guide hood by a pipe. The top air guide hood is fixedly connected to the mounting bracket. There are two bottom air guide hoods. The two bottom air guide hoods are fixedly connected to the mounting plate. The storage slot is connected to the two bottom air guide hoods by a pipe.

[0022] A high-pressure blower is fixed to the collection box, which is connected to the top and bottom air guides via pipes. The blower drives the air intake and the storage tank inside the collection box, creating negative pressure in the storage tank. This causes the pruned branches and leaves to be sucked into the storage tank through the top and bottom air guides. Baffles are installed inside the storage tank to prevent branches and leaves from being sucked into the air intake of the high-pressure blower.

[0023] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up three trimming mechanisms, the trimming device can trim the top and sides of the tree simultaneously, improving work efficiency. Furthermore, the trimming mechanism can adjust the trimming length according to the width and height of the tree, improving the versatility of the device.

[0024] 2. Through this angle adjustment mechanism, a rotating plate initially positioned above the chain and blade, and in front of the cutting direction, first contacts the branch, then rotates while adhering to the branch. An angle sensor detects the angle of rotation of the support shaft, and then detects the angle between the branch and the blade. This allows the blade of the cutting device to adjust the cutting angle according to the growth of the branch, preventing the branch from deviating from the predetermined cutting direction and improving the cutting effect.

[0025] 3. By setting up a recycling mechanism, the cut branches are sucked into the collection box, eliminating the need for manual cleaning and reducing labor costs. Attached Figure Description

[0029] Example: Figure 1 As shown, the present invention provides a technical solution for a garden leaf trimming device with angle adjustment function. The trimming device includes a base 1, a robotic arm 2, a trimming mechanism 3, a retrieval mechanism 4, and an angle adjustment mechanism 5. The base 1 and the robotic arm 2 are fixedly connected. There are three angle adjustment mechanisms 5. The robotic arm 2 and one angle adjustment mechanism 5 are fixedly connected. There are three trimming mechanisms 3. The three trimming mechanisms 3 are fixedly connected to the three angle adjustment mechanisms 5 respectively. The retrieval mechanism 4 is fixedly connected to the base 1 and the trimming mechanism 3.

[0030] The robotic arm 2 is mounted on a base 1, which can be installed on a trolley or other moving mechanism to drive the trimming device to automatically trim the leaves of the garden trees. The moving end of the robotic arm 2 is fixed to an angle adjustment mechanism 5, which is also fixed to a trimming mechanism 3. The trimming mechanism 3 is fixed to two other angle adjustment mechanisms 5 on both sides, and the other two angle adjustment mechanisms 5 are fixed to the trimming mechanism 3 and the other two trimming mechanisms 3, so that the other two trimming mechanisms 3 are located on both sides of the top trimming mechanism 3, allowing it to trim the top and sides of the tree simultaneously. The angle adjustment mechanism 5 adjusts the tilt angle of the trimming mechanism 3 to make the trimming part as perpendicular as possible to the branch to be trimmed, reducing the vibration of the trimming part caused by the reaction force of the branch during trimming, and preventing the branch from twisting when the trimming part comes into contact with the branch, which would cause the blade to slip and affect the trimming effect. The recovery mechanism 4 generates negative pressure to suck the trimmed branches and leaves into the storage box.

[0031] like Figures 2-4 As shown, the cutting mechanism 3 includes a mounting frame 31, a drive unit 32, a chain 33, cutting tools 34, a length adjustment unit 35, and a fixing plate 36. The mounting frame 31 is fixedly connected to the angle adjustment mechanism 5, the drive unit 32 is fixedly connected to the mounting frame 31, and the drive unit 32 is connected to the chain 33 via transmission.

One fixing plate 36 is fixedly connected to the mounting frame 31, and the other fixing plate 36 is fixedly connected to the length adjustment unit 35.

[0032] The angle adjustment mechanism 5 is fixed by the mounting bracket 31, which can adjust the angle of the cutting tool 34. The drive unit 32, which is fixed on the mounting bracket 31, is connected to the chain 33. The drive unit 32 drives the chain 33 to rotate at high speed, so that the cutting tools 34 on the chain 33 move at high speed with the chain 33, thereby cutting the branches. The length adjustment unit 35 is slidably connected to the cutting tool 34, which guides the chain 33 so that the track of the chain 33 is concave. The length adjustment unit 35 drives the chain 33 to move, making the concave groove smaller and the concave chain 33 on one side longer, thereby adjusting the cutting length. The other two cutting mechanisms 3 are installed on both sides of the top cutting mechanism 3 by two fixing plates 36 respectively installed on the mounting bracket 31 and the length adjustment unit 35.

[0033] like Figures 2-5As shown, the length adjustment unit 35 includes a mounting plate 351, a connecting shaft 352, a guide post 353, a connecting plate 354, and a cylinder 355. The mounting plate 351 and the mounting frame 31 are slidably connected. There are two connecting shafts 352, which are rotatably connected to the mounting plate 351. One connecting shaft 352 is fixedly connected to the drive unit 32, and the other connecting shaft 352 is fixedly connected to the guide post 353. The mounting frame 31 has two sliding grooves 311, and the two connecting shafts 352 are slidably connected to the two sliding grooves 311 respectively. The connecting plate 354 and the mounting plate 351 are fixedly connected. The cylinder 355 and the mounting frame 31 are fixedly connected, and the output end of the cylinder 355 is fixedly connected to the connecting plate 354.

[0034] Two connecting shafts 352 are mounted on the mounting plate 351. One connecting shaft 352 is fixed to the drive unit 32, and the other connecting shaft 352 is fixed to the guide post 353, so that the track of the chain 33 is U-shaped. The guide post 353 is located on the concave side of the chain 33, and the drive unit 32 connected to the connecting shaft 352 is located on the protruding position on one side. A connecting plate 354 is fixed on the mounting plate 351, and a cylinder 355 is fixed on the mounting bracket 31. The output end of the cylinder 355 is fixed to the connecting plate 354, so that the cylinder 355 can drive the mounting plate 351 to move. The connecting shaft 352 is slidably connected to two sliding grooves 311 respectively, so that the mounting plate 351 slides along the sliding grooves 311, thereby adjusting the cutting length.

[0035] like Figure 2 and Figure 6 As shown, the cutting tool 34 includes a fixed frame 341 and a blade 342. The guide post 353 is provided with a limiting groove 3531 and a storage groove 3532. The fixed frame 341 and the blade 342 are fixedly connected. The fixed frame 341 and the chain 33 are fixedly connected. The limiting groove 3531 and the fixed frame 341 are slidably connected.

[0036] The blade 342 is welded to the fixing frame 341 welded to the chain 33, allowing the blade 342 to move with the chain 33 and thus prune the tree. The guide post 353 is provided with a storage groove 3532 to prevent the blade 342 from contacting the guide post 353. The guide post 353 is provided with a limiting groove 3531, which is slidably connected to the fixing frame 341 to prevent the chain 33 from sliding out of the guide post 353.

[0037] like Figure 2 , Figure 3 and Figure 5As shown, the drive unit 32 includes a drive motor 321, a transmission shaft 322, and a sprocket 323. The drive motor 321 is fixedly connected to the mounting bracket 31. There are three transmission shafts 322 and four sprockets 323. The output end of the drive motor 321 is fixedly connected to one transmission shaft 322. The three transmission shafts 322 are rotatably connected to the mounting bracket 31. The four sprockets 323 cooperate with the chain 33. The three transmission shafts 322 and the three sprockets 323 are fixedly connected. A connecting shaft 352 is fixedly connected to another sprocket 323.

[0038] Drive motor 321 fixed on mounting bracket 31, sprocket 323 and chain 33 cooperate, chain 33 is sleeved on four sprockets 323 and guide post 353, so that the track of chain 33 is concave. The output end of drive motor 321 is fixed to a transmission shaft 322, so that drive motor 321 can drive the connected transmission shaft 322 to rotate. Sprocket 323 is installed on transmission shaft 322, so that sprocket 323 rotates with transmission shaft 322, thereby sprocket 323 drives chain 33 to rotate.

[0039] like Figure 5 and Figure 8 As shown, the angle adjustment mechanism 5 includes a detection unit 51, a connecting block 52, a rotating shaft 53, a connecting seat 54, and a rotating motor 55. The detection unit 51 is fixedly connected to the mounting bracket 31, the connecting block 52 is rotatably connected to the rotating shaft 53, the connecting seat 54 is fixedly connected to the rotating shaft 53, the rotating motor 55 is fixedly connected to the connecting block 52, and the output end of the rotating motor 55 is fixedly connected to the rotating shaft 53.

[0040] The angle between the branch and the blade 342 is detected by the detection unit 51 set on the mounting bracket 31. The two ends of the rotating shaft 53 are fixedly connected to the connecting seat 54, which is fixedly installed on the mounting bracket 31. The connecting block 52 is rotatably connected to the rotating shaft 53. The rotating motor 55 is fixedly installed on the connecting block 52 through the base. The output end of the rotating motor 55 is fixed to the rotating shaft 53, so that the rotating motor 55 can drive the rotating shaft 53 to rotate, thereby causing the connecting seat 54 to drive the mounting bracket 31 to rotate, thereby changing the tilt angle of the blade 342.

[0041] like Figure 9 As shown, the detection unit 51 includes a sliding block 511, a rotating plate 512, a support shaft 513, and an angle sensor 514. There are two support shafts 513, which are fixedly connected to the rotating plate 512. The two support shafts 513 are rotatably connected to the two sliding blocks 511 respectively. The angle sensor 514 is fixedly connected to the sliding block 511, and the detection end of the angle sensor 514 is fixedly connected to a support shaft 513.

[0042] Support shafts 513 are fixed on both sides of the rotating plate 512. The sliding blocks 511 on both sides are rotatably connected to the support shafts 513, thereby supporting the rotating plate 512 at both ends. The initial position of the rotating plate 512 is above the chain 33 and the blade 342, and in front of the cutting direction, so that the rotating plate 512 can contact the branch before the blade 342. The rotating plate 512 fits against the branch and rotates. An angle sensor 514 fixed on the sliding block 511 and whose detection end is fixed on the support shaft 513 can detect the rotation angle of the support shaft 513, and thus detect the angle between the branch and the blade 342.

[0043] like Figure 9 As shown, the detection unit 51 also includes a reset spring 515. The mounting bracket 31 is provided with two guide grooves 312. There are two reset springs 515. The two reset springs 515 are respectively placed in the two guide grooves 312. The two sliding blocks 511 are respectively fixedly connected to the two reset springs 515 and slidably connected to the two guide grooves 312.

[0044] The mounting bracket 31 has two guide grooves 312, and a return spring 515 is installed in each of the two guide grooves 312. The return spring 515 and the sliding block 511 are fixed together. After the rotating plate 512 contacts the branch, the mounting bracket 31 continues to move. Under the reaction force of the branch, the rotating plate 512 can push the sliding block 511 to overcome the elastic force of the return spring 515 and slide into the guide groove 312, so as to avoid the rotating plate 512 affecting the cutting blade 342 to cut the branch.

[0045] like Figure 1 , Figure 4 and Figure 10 As shown, the recycling mechanism 4 includes a high-pressure blower 41, a collection box 42, a baffle 43, a top air guide hood 44, and a bottom air guide hood 45. The high-pressure blower 41 and the collection box 42 are fixedly connected. The collection box 42 is provided with a storage slot 421. The baffle 43 is placed in the storage slot 421. The suction end of the high-pressure blower 41 is connected to the storage slot 421 by a pipe. The storage slot 421 is connected to the top air guide hood 44 by a pipe. The top air guide hood 44 is fixedly connected to the mounting bracket 31. There are two bottom air guide hoods 45. The two bottom air guide hoods 45 are fixedly connected to the mounting plate 351. The storage slot 421 is connected to the two bottom air guide hoods 45 by a pipe.

[0046] A high-pressure blower 41 is fixed to the collection box 42, which is connected to the top air guide hood 44 and the bottom air guide hood 45 through pipes. The high-pressure blower 41 is driven, and the suction end of the high-pressure blower 41 is connected to the storage tank 421 inside the collection box 42 through pipes, so that the storage tank 421 generates negative pressure, so that the cut branches and leaves are sucked into the storage tank 421 through the top air guide hood 44 and the bottom air guide hood 45. By installing a baffle 43 in the storage tank 421, branches and leaves are prevented from being sucked into the suction port of the high-pressure blower 41.

[0047] Working principle: Driven by cylinder 355, the output end of cylinder 355 pushes the connecting plate 354 to move, causing the mounting plate 351 to slide along the sliding groove 311. This, in turn, moves the sprocket 323 and guide post 353 on the connecting shaft 352, causing the U-shaped chain 33 to elongate one side of its protrusion, thus adjusting the cutting length. The device is then adjusted to the desired cutting length. Driven by motor 321, the transmission shaft 322 rotates at high speed, driving the sprocket 323 to rotate at high speed. This causes the chain 33 to move at high speed along the sprocket 323 and guide post 353, which in turn drives the blade 342 mounted on the chain 33 to move at high speed. The rotating plate 51, initially positioned above the chain 33 and blade 342 and in front of the cutting direction, moves the blade at high speed. 2. The rotating plate 512 contacts the branch before the blade 342. The rotating plate 512 adheres to the branch and rotates. The angle sensor 514 detects the rotation angle of the support shaft 513, and then detects the angle between the branch and the blade 342. The rotating motor 55 drives the rotating shaft 53 to rotate, thereby causing the connecting seat 54 to drive the mounting bracket 31 to rotate, thereby changing the tilt angle of the blade 342. The mounting bracket 31 continues to move, and the rotating plate 512 pushes the sliding block 511 to slide into the guide groove 312 against the elastic force of the return spring 515, thereby causing the blade 342 to cut the branch. The high-pressure blower 41 is driven to generate negative pressure in the storage tank 421, so that the cut branches and leaves are sucked into the storage tank 421 through the top air guide shroud 44 and the bottom air guide shroud 45.

[0048] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
