[0083] Example 1

[0084] Please see Figure 1 , Figures 3 to 8 As shown, the present invention discloses a fruit cutting device 100, which is capable of cutting and harvesting bunches of oil palm fruits on oil palm trees. The fruit cutting device 100 includes:

[0085] An arc-shaped support body 1 has an arc-shaped movable channel 11 extending through it along the circumference. The inner sidewall of the arc-shaped support body 1 has an arc-shaped clearance groove 12 connected to the arc-shaped movable channel 11 along the circumference. A clamping opening 13 is formed between the two ends of the arc-shaped support body 1, so that the arc-shaped support body 1 can clamp the trunk of the fruit tree through the clamping opening 13.

[0086] Arc-shaped track 2, which is slidably fitted inside arc-shaped movable channel 11, so that arc-shaped track 2 can move along arc-shaped movable channel 11;

[0087] Cutting mechanism 3: A cutting mechanism 3 is provided above both ends of the arc-shaped support body 1. The cutting mechanism 3 is connected to the arc-shaped track 2 through a first connecting piece 4. The first connecting piece 4 passes through the arc-shaped relief groove 12, so that when the arc-shaped track 2 moves along the arc-shaped movable channel 11, it can drive the first connecting piece 4 and the cutting mechanism 3 to move together, so that the cutting mechanism 3 can move to the required position according to actual needs.

[0088] A driving mechanism 5 is located between the arc-shaped track 2 and the arc-shaped support body 1. The driving mechanism 5 drives the arc-shaped track 2 to move the cutting mechanism 3 along the circumferential direction. In a specific implementation of this invention, both the arc-shaped support body 1 and the arc-shaped track 2 are designed as arc structures, and the arcs of both are superior arcs to ensure that the two cutting mechanisms 3 can cover 360° around the fruit tree for harvesting and cutting without blind spots.

[0089] This invention designs an arc-shaped support body 1 with an arc-shaped movable channel 11 and an arc-shaped clearance groove 12, and slides an arc-shaped track 2 within the arc-shaped movable channel 11. A driving mechanism 5 is provided between the arc-shaped track 2 and the arc-shaped support body 1. At the same time, a cutting mechanism 3 is provided above both ends of the arc-shaped support body 1, and the cutting mechanism 3 is connected to the arc-shaped track 2 through a first connecting member 4. In actual operation, the driving mechanism 5 can drive the arc-shaped track 2 to move the two cutting mechanisms 3 along the circumferential direction. Through the cooperation of the two cutting mechanisms 3, it can be ensured that 360° coverage can be achieved to achieve harvesting and cutting without dead angles, which can bring great convenience to actual harvesting.

[0090] In Embodiment 1 of the present invention, in order to achieve the cutting function, please refer to the following: Figure 7 and Figure 8 As shown, the cutting mechanism 3 includes:

[0091] A fixed base 35 is connected to a first connecting member 4, enabling the first connecting member 4 to drive the entire cutting mechanism 3 to move together with the arc track 2;

[0092] A rotating base 36 is provided above the fixed base 35 and hinged to the fixed base 35, so that the rotating base 36 can rotate relative to the fixed base 35.

[0093] A first cutting component 37 for cutting fruit, the lower end of the first cutting component 37 is hinged to one end of a rotating base 36, so that the first cutting component 37 can rotate relative to the rotating base 36;

[0094] An automatic angle adjustment component 38 is disposed between the first cutting component 37 and the rotating base 36, and between the fixed base 35 and the rotating base 36. The automatic angle adjustment component 38 drives the first cutting component 37 to adjust its angle, so that the first cutting component 37 can better cut and harvest the oil palm fruit.

[0095] In one specific embodiment of the present invention, the first cutting component 37 includes:

[0096] First top support 371;

[0097] The first telescopic guide rod 372 has its lower end hinged to one end of the rotating base 36, allowing it to rotate relative to the rotating base 36. The upper end of the first telescopic guide rod 372 is connected to the first top support 371. The first telescopic guide rod 372 guides the movement of the first top support 371 to ensure the stability of the first top support 371 during movement.

[0098] The first drive cylinder 373 has its lower end hinged to the lower end of the first telescopic guide rod 372, and its upper end hinged to the first top support 371, so as to drive the first top support 371 to move upward or downward; wherein, the first drive cylinder 373 can be a hydraulic cylinder or a pneumatic cylinder as needed.

[0099] The first vibration cylinder 374 is mounted on the first top support 371.

[0100] The first cutting tool 375 is connected to the first vibrating cylinder 374.

[0101] In a specific implementation of the present invention, a vision device 376 may also be provided on the first top support 371, and the vision device 376 faces the first cutting tool 375. During use, the vision device 376 can be used to capture images of the first cutting tool 375 so as to adjust the first cutting tool 375 according to the captured images.

[0102] In practical operation, the first cutting component 37 of this invention, after adjusting the first cutting blade 375 to the desired cutting position, drives the first top support 371 via the first drive cylinder 373 to move the first cutting blade 375, thus achieving the cutting operation. Simultaneously, during the cutting process, the first vibration cylinder 374 drives the first cutting blade 375 to vibrate, making the first cutting blade 375 more powerful during cutting. This invention utilizes the design of the first drive cylinder 373 to drive the first top support 371 to move the first cutting blade 375 up and down to achieve cutting. Because the extension and retraction movement of the first drive cylinder 373 is rapid, it can quickly cut the fruit of the oil palm tree, thereby improving cutting and harvesting efficiency. Furthermore, the first cutting blade 375 is also equipped with the first vibration cylinder 374, which drives the first cutting blade 375 to vibrate during the cutting process, making the first cutting blade 375 more powerful during cutting.

[0103] Furthermore, such as Figure 6As shown, when the first cutting blade 375 is a Y-shaped blade, the first driving cylinder 373 drives the first cutting blade 375 to rise to achieve cutting. In a specific implementation of the present invention, when the first cutting blade 375 is a Y-shaped blade, before cutting, the first cutting blade 375 needs to be positioned below the stalk of the oil palm fruit. During cutting, the first driving cylinder 373 pushes the first cutting blade 375 upward quickly, so that the first cutting blade 375 can quickly cut off the stalk of the oil palm fruit. At the same time, when the outer side of the oil palm fruit is blocked by a petiole, before cutting, the first cutting blade 375 needs to be positioned below the petiole. During cutting, the first driving cylinder 373 pushes the first cutting blade 375 upward quickly, so that the first cutting blade 375 can quickly cut off both the petiole and the stalk of the oil palm fruit.

[0104] like Figure 8 As shown, when the first cutting tool 375 is an inverted L-shaped tool or a T-shaped tool with double-sided cutting edges, the first driving cylinder 373 drives the first cutting tool 375 to descend and achieve cutting. In a specific implementation of the present invention, when the first cutting tool 375 is an inverted L-shaped tool, before cutting, the first cutting tool 375 needs to be positioned above the stalk of the oil palm fruit. During cutting, the first driving cylinder 373 is used to quickly pull the first cutting tool 375 down so that the first cutting tool 375 can quickly cut off the stalk of the oil palm fruit. Of course, if there is a leaf petiole blocking the outside of the oil palm fruit, the first cutting tool 375 can cut off the stalk of the oil palm fruit and the leaf petiole together.

[0105] In one specific embodiment of the present invention, the automatic angle adjustment component 38 includes:

[0106] The second drive cylinder 381 has its lower end hinged to the other end of the rotating base 36 and its upper end hinged to the first cutting assembly 37, specifically to the first telescopic guide rod 372 of the first cutting assembly 37. The second drive cylinder 381 is located on the side opposite to the first drive cylinder 373 and is used to adjust the first angle formed between the rotating base 36 and the first cutting assembly 37.

[0107] The third drive cylinder 382 has its upper end hinged to any side of the rotating base 36 and its lower end hinged to the fixed base 35. The third drive cylinder 382 is used to adjust the second angle formed between the rotating base 36 and the fixed base 35. In a specific implementation of the present invention, the second drive cylinder 381 and the third drive cylinder 382 can be hydraulic cylinders or pneumatic cylinders.

[0108] In practical use, the automatic angle adjustment component 38 of the present invention can be driven by the second drive cylinder 381 to rotate the first cutting component 37 relative to the rotating base 36, so as to move the first cutting component 37 towards the direction closer to the oil palm tree trunk or away from the oil palm tree trunk, that is, to move the first cutting component 37 back and forth; at the same time, the third drive cylinder 382 can also be used to drive the rotating base 36 relative to the fixed base 35 to rotate, so as to move the first cutting component 37 left and right to swing.

[0109] Because the height and taper (i.e., the taper formed by the gradual reduction in diameter of the trunk from bottom to top) of oil palm trees planted at different times vary considerably, this invention addresses this issue by incorporating an automatic angle adjustment component 38 between the first cutting component 37 and the rotating base 36, and between the fixed base 35 and the rotating base 36. Specifically, the automatic angle adjustment component 38 includes a second drive cylinder 381 located between the first cutting component 37 and the rotating base 36, and a third drive cylinder 382 located between the fixed base 35 and the rotating base 36. During operation, the second drive cylinder 381 can be used to move the first cutting component 37 towards or away from the oil palm tree trunk (i.e., forward and backward adjustment), and the third drive cylinder 382 can be used to swing the first cutting component 37 left and right. Therefore, this invention effectively achieves automatic adjustment of the tilt angle of the first cutting component 37, enabling it to meet the cutting needs of fruits from trees of varying heights and tapers, and ensuring better alignment of the first cutting component with the fruits on the oil palm tree, thereby improving cutting efficiency.

[0110] In Embodiment 1 of the present invention, please refer to the following: Figure 4 As shown, the arc-shaped support body 1 includes:

[0111] The main support frame 14 is formed by the arc-shaped outer side plate 141, the arc-shaped top plate 142 and the arc-shaped bottom plate 143;

[0112] Two arc-shaped inner side plates 15 are respectively located on the upper and lower parts of the inner side of the main support frame 14, and an arc-shaped relief groove 12 is formed between the two arc-shaped inner side plates 15.

[0113] The second connector 16, each of the arc-shaped inner side plates 15 is detachably connected to the main support frame 14 through a number of second connectors 16, so as to meet the support requirements of the arc-shaped inner side plates 15 by using the second connectors 16.

[0114] Arc-shaped abutment block 17: Each of the arc-shaped inner side plates 15 is provided with an arc-shaped abutment block 17 on the side facing the arc-shaped moving channel 11, and the arc-shaped abutment block 17 abuts against the inner side of the arc-shaped track 2, wherein the arc-shaped abutment block 17 is connected to the arc-shaped inner side plate 15.

[0115] The present invention designs an arc-shaped support body 1 including upper and lower arc-shaped inner side plates 15 located inside the main support frame 14, forming an arc-shaped relief groove 12 between the two arc-shaped inner side plates 15. The arc-shaped inner side plates 15 are detachably connected to the main support frame 14 via a second connector 16. An arc-shaped abutment block 17 is provided on the side of the arc-shaped inner side plate 15 facing the arc-shaped movable channel 11. This allows for convenient disassembly and assembly of the arc-shaped track 2 during actual use, and the arc-shaped abutment block 17 can be used to abut the inner side of the arc-shaped track 2 to improve the stability of the arc-shaped track 2 during movement.

[0116] In Embodiment 1 of the present invention, the top and bottom of the arc-shaped support body 1 are provided with a plurality of connecting openings 18 that communicate with the arc-shaped movable channel 11. Abutting roller 6 is rotatably provided at the top and bottom of the arc-shaped support body 1 at the position corresponding to each connecting opening 18. The abutting roller 6 abuts against the upper or lower surface of the arc-shaped track 2. Specifically, the abutting roller 6 at the top of the arc-shaped support body 1 abuts against the upper surface of the arc-shaped track 2, and the abutting roller 6 at the bottom of the arc-shaped support body 1 abuts against the lower surface of the arc-shaped track 2. By adopting the above structural design, on the one hand, the abutting rollers 6 can provide support and limit the arc-shaped track 2, allowing the arc-shaped track 2 to move smoothly along the arc-shaped movable channel 11; on the other hand, because the abutting roller 6 itself can rotate, the friction between the abutting roller 6 and the arc-shaped track 2 can be effectively reduced, ensuring that the arc-shaped track 2 can move smoothly.

[0117] In Embodiment 1 of the present invention, please refer to the following: Figure 5 As shown, the drive mechanism 5 includes:

[0118] The drive motor 51 is installed in the middle of the outer side of the arc-shaped support body 1. Specifically, the drive motor 51 can be located in the middle of the outer side of the arc-shaped support body 1.

[0119] A drive sprocket 52 is connected to the output end of a drive motor 51 so that the drive motor 51 can drive the drive sprocket 52 to rotate.

[0120] The transmission chain 53 is fixedly installed in the chain mounting groove 21 along the circumferential direction on the outer side of the arc-shaped track 2. The drive sprocket 52 meshes with the transmission chain 53. Because the outer surface of the arc-shaped track 2 is an arc-shaped curved surface, the transmission chain 53 and the drive sprocket 52 work together to drive the arc-shaped track 2 to move, which can better adapt to the arc-shaped curved surface.

[0121] The cutting method of the fruit cutting device 100 of the present invention is as follows: After the arc-shaped support body 1 clamps the trunk of the oil palm tree, the drive mechanism 5 drives the arc-shaped track 2 to move the two cutting mechanisms 3, so that one of the cutting mechanisms 3 moves along the circumference to the position of the oil palm fruit to be picked; the clamping components 32 of the two cutting mechanisms 3 are controlled to clamp the trunk of the oil palm tree, and at the same time the angle automatic adjustment component 38 is controlled to automatically adjust the first cutting component 37 back and forth and / or left and right, so that the first cutting component 37 can cut the oil palm fruit more accurately; finally, the first cutting component 37 of the cutting mechanism 3 is controlled to cut the oil palm fruit.

[0122] Example 2

[0123] Please see Figures 2 to 6 as well as Figures 9 to 12 As shown, the fruit cutting device 100 of the present invention differs from that of Embodiment 1 in that:

[0124] In the second embodiment of the present invention, in order to achieve the clamping and cutting functions, please refer to the following: Figures 9 to 12 As shown, the cutting mechanism 3 includes:

[0125] The support base 31 is connected to the first connecting member 4, so that the first connecting member 4 can drive the entire cutting mechanism 3 to move together with the arc track 2.

[0126] The clamping component 32 is used to clamp the trunk of the fruit tree. The clamping component 32 is mounted on the support base 31. The movable ends of the clamping components 32 on the two cutting mechanisms 3 are arranged facing each other. During cutting, the clamping components 32 of the two cutting mechanisms 3 can be used to clamp the trunk of the oil palm tree to ensure the stability of the cutting mechanism 3 during cutting.

[0127] A second cutting component 33 for cutting fruit, one bottom end of which is hinged to a support base 31;

[0128] A manual angle adjustment component 34 is provided, located between the other end of the bottom of the second cutting component 33 and the support base 31. Because the height and taper (i.e., the taper formed by the trunk gradually decreasing from bottom to top) of oil palm trees planted at different times vary considerably, this invention, by setting the manual angle adjustment component 34 between the other end of the bottom of the second cutting component 33 and the support base 31, allows for adjustment of the angle between the second cutting component 33 and the support base 31 during actual use. This enables adjustment of the tilt angle of the second cutting component 33, allowing it to meet the cutting needs of oil palm fruits of different heights and tapers, thus improving its flexibility. In practical implementation, since oil palm trees in the same row are usually planted at the same time, their height and taper are roughly the same, and the positions of the fruits are also similar. Therefore, frequent adjustment of the angle between the second cutting component 33 and the support base 31 is unnecessary; adjustment is only required when the height, taper, and fruit positions of the oil palm trees differ significantly.

[0129] In a specific implementation of the present invention, in order to make the overall structure of the entire cutting mechanism 3 more compact and aesthetically pleasing, the support base 31 includes a support base plate 311 and support side plates 312 fixed on both sides of the support base plate 311. The support base plate 311 is fixed on the first connecting member 4, the clamping assembly 32 is arranged horizontally between the two support side plates 312, one end of the bottom of the second cutting assembly 33 is hinged to the middle of the two support side plates 312, and the lower end of the angle manual adjustment assembly 34 is rotatably connected to the ends of the two support side plates 312.

[0130] In one specific embodiment of the present invention, the second cutting component 33 includes:

[0131] The bottom bracket 331 is connected to the support base 31. Specifically, one end of the bottom bracket 331 is hinged to the support base 31, so that the bottom bracket 331 can rotate relative to the support base 31.

[0132] Second top support 332;

[0133] The fourth drive cylinder 333 is located between the bottom support 331 and the second top support 332, so as to drive the second top support 332 to move upward or downward; wherein, the fourth drive cylinder 333 can be a hydraulic cylinder or a pneumatic cylinder according to actual needs.

[0134] The second telescopic guide rod 334 is disposed between the bottom bracket 331 and the second top bracket 332; the second telescopic guide rod 334 is used to guide the movement of the second top bracket 332 to ensure the stability of the movement of the second top bracket 332.

[0135] The second vibration cylinder 335 is mounted on the second top bracket 332;

[0136] The second cutting tool 336 is connected to the second vibrating cylinder 335.

[0137] In specific operation, when the second cutting component 33 of the present invention is adjusted to the required cutting position, the second top support 332 is driven by the fourth drive cylinder 333 to drive the second cutting tool 336 to move and realize the cutting operation. At the same time, during the cutting process, the second vibration cylinder 335 is used to drive the second cutting tool 336 to vibrate, so that the second cutting tool 336 is more powerful when cutting.

[0138] This invention utilizes a fourth drive cylinder 333 to drive a second top support 332, which in turn drives a second cutting blade 336 to move up and down to achieve cutting. Because the fourth drive cylinder 333 moves quickly, it can quickly cut the fruit of the oil palm tree, thereby improving cutting and harvesting efficiency. At the same time, the second cutting blade 336 is also equipped with a second vibration cylinder 335. During the cutting process, the second vibration cylinder 335 drives the second cutting blade 336 to vibrate, making the second cutting blade 336 more powerful when cutting.

[0139] Furthermore, such as Figure 6 As shown, when the second cutting blade 336 is a Y-shaped blade, the fourth driving cylinder 333 drives the second cutting blade 336 to rise to achieve cutting. In a specific implementation of the present invention, when the second cutting blade 336 is a Y-shaped blade, before cutting, the second cutting blade 336 needs to be positioned below the stalk of the oil palm fruit. During cutting, the fourth driving cylinder 333 pushes the second cutting blade 336 upward quickly, enabling the second cutting blade 336 to quickly cut off the stalk of the oil palm fruit. At the same time, when the outer side of the oil palm fruit is blocked by a leaf stalk, before cutting, the second cutting blade 336 needs to be positioned below the leaf stalk. During cutting, the fourth driving cylinder 333 pushes the second cutting blade 336 upward quickly, enabling the second cutting blade 336 to quickly cut off both the leaf stalk and the stalk of the oil palm fruit.

[0140] like Figure 10As shown, when the second cutting tool 336 is an inverted L-shaped tool or a T-shaped tool with double-sided cutting edges, the fourth drive cylinder 333 drives the second cutting tool 336 to descend and achieve cutting. In a specific implementation of the present invention, when the second cutting tool 336 is an inverted L-shaped tool, before cutting, the second cutting tool 336 needs to be positioned above the stalk of the oil palm fruit. During cutting, the fourth drive cylinder 333 is used to quickly pull the second cutting tool 336 down so that the second cutting tool 336 can quickly cut off the stalk of the oil palm fruit. Of course, if there is a petiole blocking the outside of the oil palm fruit, the second cutting tool 336 can cut off the stalk and petiole of the oil palm fruit together.

[0141] In one specific embodiment of the present invention, the clamping assembly 32 includes:

[0142] The fifth drive cylinder 321 is arranged horizontally on the support base 31. The fifth drive cylinder 321 can be a hydraulic cylinder or a pneumatic cylinder as needed.

[0143] A clamping plate 322 is connected to the movable end of the fifth drive cylinder 321. During operation, before cutting, the clamping assembly 32 is driven by the fifth drive cylinder 321 to move the clamping plate 322 inward toward the trunk and press it firmly against the outer surface of the trunk; after cutting, the clamping plate 322 is driven outward away from the trunk by the fifth drive cylinder 321.

[0144] In one specific embodiment of the present invention, the angle manual adjustment component 34 includes:

[0145] Adjusting screw 341, the lower end of which is provided with a connecting part 3411;

[0146] A connecting shaft 342 is mounted on a support base 31, and a connecting part 3411 is rotatably connected to the connecting shaft 342, so that the adjusting screw 341 can rotate relative to the support base 31;

[0147] The connecting block 343 is rotatably disposed at the other end of the bottom of the second cutting assembly 33. Specifically, the connecting block 343 is rotatably disposed on the bottom support 331 of the second cutting assembly 33. A screw through hole 3431 is provided through the connecting block 343, and the upper end of the adjusting screw 341 passes through the screw through hole 3431.

[0148] Locking nuts 344 are screwed onto the adjusting screw 341 at both the upper and lower positions corresponding to the connecting block 343. When adjusting the angle manual adjustment component 34 of this invention, the locking nuts 344 at the upper or lower position need to be rotated away from the connecting block 343. After adjusting the angle between the second cutting component 33 and the support base 31, the two locking nuts 344 are then tightened towards each other.

[0149] It should be noted that, apart from the differences mentioned above, the other structures of the fruit cutting device 100 in Embodiment 2 of the present invention are completely different from those in Embodiment 1. For details, please refer to the detailed description of Embodiment 1, which will not be repeated here.

[0150] The cutting method of the fruit cutting device 100 of the present invention is as follows: According to the height, taper and position of the oil palm tree and the oil palm fruit, the angle between the second cutting component 33 and the support base 31 is adjusted by the angle manual adjustment component 34 so that the second cutting component 33 can cut the oil palm fruit more accurately; after the arc-shaped support body 1 clamps the trunk of the oil palm tree, the drive mechanism 5 drives the arc-shaped track 2 to move the two cutting mechanisms 3, so that one of the cutting mechanisms 3 moves along the circumference to the position of the oil palm fruit to be picked; the clamping components 32 of the two cutting mechanisms 3 are controlled to clamp the trunk of the oil palm tree, and the second cutting component 33 of the cutting mechanism 3 is controlled to cut the oil palm fruit.
