Description

Technical Field

[0001] This invention relates to the field of harvesting equipment technology, specifically a 360-degree harvesting attachment with a fruit-catching basket. Background Technology

[0002] Palm fruit, also known as oil palm fruit, consists of an outer layer of pulp containing 45%–50% oil and an inner hard kernel. The pulp can be used to extract bark oil, while the kernel can be used to extract palm kernel oil. Palm fruits grow on palm trees, typically at higher elevations and in clusters. Each palm tree usually produces about 10–15 clusters, with each cluster weighing between 15–25 kilograms.

[0003] To improve overall harvesting efficiency, automated harvesting equipment is commonly used for palm fruit harvesting. Harvesting and cutting devices are a crucial component of these automated systems, as exemplified by Chinese invention patent CN202511341468.1, filed on September 19, 2025. However, these existing cutting devices have the following drawbacks in practical use: 1. They cannot catch the fruit falling during cutting. While some cutting devices are equipped with hoppers, the hopper requires a robotic arm to rotate and empty the fruit after it has been caught, which is inconvenient and affects harvesting efficiency; 2. They cannot reliably limit the circumferential movement of the cutting mechanism; 3. During cutting, the cutting device cannot firmly grip the tree trunk, resulting in poor cutting stability; 4. The upper and lower surfaces of the curved track are supported by multiple rollers, which, due to their spacing, cause the curved track to vibrate during operation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a 360-degree harvesting attachment with a fruit-catching basket, which solves the problems of existing cutting devices that cannot catch the fruit that falls during cutting or rely on a robotic arm to rotate the hopper to pour the fruit out, cannot reliably limit the circumferential movement of the cutting mechanism, cannot hold the fruit tree trunk tightly during cutting, have poor cutting stability, and are prone to shaking during the operation of the arc track.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A 360-degree harvesting attachment with a fruit-receiving basket includes an arc-shaped support body, an arc-shaped track movably mounted in the arc-shaped support body along the circumferential direction, a cutting mechanism connected to both ends of the arc-shaped track and located above the arc-shaped support body, a drive mechanism that drives the arc-shaped track to drive the two cutting mechanisms to cover 360° cutting, and two fruit-receiving baskets. The fruit-receiving baskets are located on the outside of the arc-shaped support body, and each fruit-receiving basket is connected to a cutting mechanism through a fruit-receiving basket connector. The fruit receiving basket includes a fixed fruit basket body, a movable fruit basket body, and an opening and closing drive component. The fixed fruit basket body is connected to the fruit basket connector. The upper end of the movable fruit basket body is rotatably connected to the upper end of the fixed fruit basket body. The opening and closing drive component is located between the fixed fruit basket body and the movable fruit basket body. The opening and closing drive component drives the movable fruit basket body to close to receive material or drives the movable fruit basket body to open to discharge material.

[0006] Furthermore, a limit stop is provided at the top center of the arc-shaped support body, and a trigger switch is provided on the limit stop; each of the cutting mechanisms is provided with a trigger baffle on the side away from the limit stop. When the drive mechanism drives the arc-shaped track to move any cutting mechanism until the trigger baffle contacts the limit stop and the trigger switch at the same time, the opening and closing drive component of the fruit basket corresponding to the cutting mechanism drives the fruit basket to open.

[0007] Furthermore, the lower end of the movable fruit basket is provided with a base plate that is adjacent to or in contact with the lower end of the fixed fruit basket in the closed state.

[0008] Furthermore, the movable fruit basket is provided with side baffles on both sides that are adjacent to or in contact with the fixed fruit basket in the closed state, and both the movable fruit basket and the fixed fruit basket are provided with end baffles at their respective ends.

[0009] Furthermore, the fruit receiving basket also includes an annular body, the upper end of the fixed fruit basket is fixedly connected to the annular body, the upper end of the movable fruit basket is rotatably connected to the annular body, and a receiving opening is formed on the inner side of the annular body.

[0010] Furthermore, it also includes at least two fruit tree tightening mechanisms, which are located below the arc-shaped support body, and the upper end of the fruit tree tightening mechanism is connected to the bottom of the arc-shaped support body.

[0011] Furthermore, the arc-shaped support body is an arc-shaped support body with an arc angle greater than or equal to 180° and less than or equal to 190°; a fruit tree tightening mechanism is provided at both ends of the arc-shaped support body, and the two fruit tree tightening mechanisms are spaced 180° apart.

[0012] Furthermore, the fruit tree tightening mechanism includes an arc-shaped abutment, a swing arm, a fixed seat, and a first drive cylinder; the fixed seat is located at the bottom of the arc-shaped support body, the upper end of the swing arm is rotatably connected to the fixed seat, the arc-shaped abutment is connected to the lower end of the swing arm and located on the inner side of the swing arm; the first drive cylinder is located on the outer side of the swing arm, and the upper end of the first drive cylinder is hinged to the fixed seat, and the lower end of the first drive cylinder is hinged to the swing arm.

[0013] Furthermore, the cutting mechanism includes a support base, a cutting tool, a rotating frame, a tool holder, a second drive cylinder, a third drive cylinder, and a fourth drive cylinder, with the fruit basket connector connected to the support base; The inner wall of the arc-shaped support body has an arc-shaped relief groove formed along the circumferential direction. The lower end of the support body passes through the arc-shaped relief groove and is connected to the arc-shaped track. The rotating frame is rotatably connected to the support body. The second drive cylinder is located between the support body and the rotating frame. The rotating frame is rotated and adjusted by the second drive cylinder. The tool holder is rotatably connected to the upper end of the rotating frame. The third drive cylinder is located between the tool holder and the rotating frame. The tool holder is oscillating and adjusted by the third drive cylinder. The fourth drive cylinder is located on the tool holder. The cutting tool is connected to the movable end of the fourth drive cylinder. The cutting tool is driven to cut by the fourth drive cylinder.

[0014] Furthermore, the arc-shaped support body has an arc-shaped movable channel running through it along the circumference, and the arc-shaped track is slidably assembled in the arc-shaped movable channel. Wear-resistant limiting plates are provided at the top and bottom of the arc-shaped movable channel for sliding contact with the arc-shaped track.

[0015] By adopting the above-described technical solution of the present invention, at least the following beneficial effects are achieved: 1. It can not only achieve 360° coverage for picking and cutting without dead angles, but also release the collected fruits directly from the bottom of the fruit receiving basket after receiving the fruits, without relying on the robotic arm to flip the fruit receiving basket to pour out the fruits, which can improve the actual picking efficiency and make it more convenient to use.

[0016] 2. By setting a limit stop at the top center of the arc-shaped support body, and setting a trigger switch on the limit stop, and setting a trigger baffle on the side of the cutting mechanism away from the limit stop, in actual use, not only can the limit stop be used to limit the circumferential movement of the cutting mechanism and ensure that the two cutting mechanisms can cover 360° picking and cutting without dead angles; but when the trigger baffle contacts the limit stop to achieve the limit, it can also trigger the opening and closing drive component of the fruit basket corresponding to the cutting mechanism to drive the fruit basket to open, so as to automatically release the fruit in the fruit basket from the bottom.

[0017] 3. By setting a bottom plate at the lower end of the movable fruit basket and side baffles on both sides of the movable fruit basket, the bottom plate and side baffles can move together with the movable fruit basket when the opening and closing drive component drives the movable fruit basket to open. This ensures that the fruit in the fruit basket can fall reliably downwards, allowing all the fruit in the fruit basket to be released without being trapped inside. At the same time, when the opening and closing drive component drives the movable fruit basket to close, the bottom plate, side baffles, and end baffles can form a storage space to store the fruit picked by the cutting mechanism.

[0018] 4. By equipping the lower part of the arc-shaped support body with a fruit tree tightening mechanism, during actual use, the fruit tree trunk can be tightened using the fruit tree tightening mechanism, so that the picking attachment can hold the fruit tree trunk tightly, thereby improving the cutting stability; moreover, the fruit tree tightening mechanism will not interfere with the cutting mechanism and the fruit receiving basket.

[0019] 5. By setting wear-resistant limiting plates at the top and bottom of the arc-shaped moving channel, and making the arc-shaped track directly slide in contact with the wear-resistant limiting plates, on the one hand, it can effectively prevent the arc-shaped track from shaking during the movement, thereby improving the stability of the arc-shaped track, cutting mechanism and fruit basket during the circular motion; on the other hand, because nylon has low frictional resistance, by designing the wear-resistant limiting plates to be nylon limiting plates, it can be ensured that the arc-shaped track can slide smoothly.

Detailed Implementation

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see the appendix Figures 1 to 9As shown, the present invention provides a 360-degree harvesting attachment 100 with a fruit-receiving basket. The harvesting attachment 100 includes an arc-shaped support body 1, an arc-shaped track 2 movably mounted within the arc-shaped support body 1 along the circumferential direction, a cutting mechanism 3 connected to both ends of the arc-shaped track 2 and located above the arc-shaped support body 1, a drive mechanism 4 that drives the arc-shaped track 2 to drive the two cutting mechanisms 3 to cover a 360° cut, and two fruit-receiving baskets 5. The fruit-receiving baskets 5 are located on the outside of the arc-shaped support body 1, and each fruit-receiving basket 5 passes through a fruit-receiving basket. The basket connector 6 is connected to a cutting mechanism 3. During operation, the arc-shaped track 2 can be driven to move by the drive mechanism 4. When the arc-shaped track 2 moves, it can drive the cutting mechanism 3 to move as well. The fruit basket 5 is connected to the cutting mechanism 3 through the fruit basket connector 6. Therefore, when the cutting mechanism 3 moves, it can drive the fruit basket 5 to move as well. At the same time, since both ends of the arc-shaped track 2 are equipped with cutting mechanisms 3, the drive mechanism 4 can be used to drive the two cutting mechanisms 3 to cover 360° without dead angles during operation. It should be noted that the specific structural design of the drive mechanism 4 is prior art. Please refer to the detailed description in CN202511341468.1 for details. It will not be repeated here.

[0024] The fruit receiving basket 5 includes a fixed fruit basket body 51, a movable fruit basket body 52, and an opening / closing drive component 53. The fixed fruit basket body 51 is connected to the fruit basket connector 6. The upper end of the movable fruit basket body 52 is rotatably connected to the upper end of the fixed fruit basket body 51, allowing the movable fruit basket body 52 to rotate relative to the fixed fruit basket body 51. The opening / closing drive component 53 is located between the fixed fruit basket body 51 and the movable fruit basket body 52. ​​The opening / closing drive component 53 drives the movable fruit basket body 52 to close for receiving material or to open for discharging material. When using the fruit receiving basket 5 of this invention, please refer to the following instructions. Figure 6 As shown, when the opening and closing drive component 53 drives the movable fruit basket part 52 to close, the movable fruit basket part 52 and the fixed fruit basket part 51 together form a closed basket body at the bottom, so as to catch the fruit (such as palm fruit) picked by the cutting mechanism 3 and falling down; please refer to the following. Figure 5 As shown, when the opening and closing drive component 53 drives the movable fruit basket 52 to open, a discharge opening 54 can be formed between the bottom of the movable fruit basket 52 and the bottom of the fixed fruit basket 51, so as to release the fruit collected in the basket from the bottom.

[0025] This invention features cutting mechanisms 3 at both ends of an arc-shaped track 2, with each cutting mechanism 3 connected to a fruit basket 5 via a fruit basket connector 6. The fruit basket 5 is designed to include a fixed fruit basket section 51, a movable fruit basket section 52, and an opening / closing drive component 53. The upper end of the movable fruit basket section 52 is rotatably connected to the upper end of the fixed fruit basket section 51, and the opening / closing drive component 53 is positioned between the fixed fruit basket section 51 and the movable fruit basket section 52. This design allows the opening / closing drive component 53 to drive the movable fruit basket section 52 and the fixed fruit basket section 51 together to form the bottom. The enclosed basket body allows it to catch the harvested fruit; the opening and closing drive component 53 can also drive the bottom of the movable part 52 and the fixed part 51 of the fruit basket to open, forming a discharge opening so that the fruit collected in the basket can be poured out. Therefore, by adopting the above-mentioned technical solution of the present invention, not only can 360° coverage without dead angles be achieved for harvesting and cutting, but after the fruit receiving basket 5 has finished receiving the fruit, the collected fruit can be directly released from the bottom of the fruit receiving basket 5 without relying on the robotic arm to drive the fruit receiving basket 5 to flip it over to pour out the fruit, which can improve the actual harvesting efficiency and make it more convenient to use.

[0026] In some embodiments of the present invention, a limiting stop 11 is provided at the top center of the arc-shaped support body 1, and a trigger switch (not shown) is provided on the limiting stop 11. The trigger switch is used to trigger the opening and closing drive component 53 to drive the movable fruit basket 52 to open, so as to release the fruit in the basket from the bottom. Each cutting mechanism 3 is provided with a trigger baffle 7 on the side away from the limiting stop 11. When the drive mechanism 4 drives the arc-shaped track 2 to move any cutting mechanism 3 to the point that the trigger baffle 7 contacts the limiting stop 11 and the trigger switch at the same time, the opening and closing drive component 53 of the fruit basket 5 corresponding to the cutting mechanism 3 drives the movable fruit basket 52 to open. In a specific implementation, the present invention can be designed so that each cutting mechanism 3 can move within a circumferential range of 190°. That is, when the trigger baffle 7 corresponding to the first cutting mechanism 3 is in contact with the limit stop 11, assuming the first cutting mechanism 3 is at a 0° position, when the driving mechanism 4 drives the arc track 2 to move the second cutting mechanism 3 until its corresponding trigger baffle 7 is in contact with the limit stop 11, the first cutting mechanism 3 will be at a 190° position. In this way, the cooperation of the two cutting mechanisms 3 can effectively achieve 360° coverage without dead angles for picking and cutting.

[0027] This invention provides a limiting stop 11 at the top center of the arc-shaped support body 1, a trigger switch on the limiting stop 11, and a trigger baffle 7 on the side of the cutting mechanism 3 away from the limiting stop 11. This allows the limiting stop 11 to limit the circumferential movement of the cutting mechanism 3 during use, ensuring that both cutting mechanisms 3 can cover 360° for harvesting and cutting without blind spots. Furthermore, when the trigger baffle 7 contacts the limiting stop 11 to achieve the limiting effect, it also triggers the opening and closing drive component 53 of the fruit basket 5 corresponding to the cutting mechanism 3, causing the movable part 52 of the fruit basket to open, thus automatically releasing the fruit from the bottom of the fruit basket 5.

[0028] In some embodiments of the present invention, the lower end of the movable fruit basket body 52 is provided with a base plate 551 that is adjacent to or in contact with the lower end of the fixed fruit basket body 51 in the closed state.

[0029] Furthermore, the movable fruit basket body 52 is provided with side baffles 552 on both sides, which are close to or in contact with the fixed fruit basket body 51 in the closed state. Both the movable fruit basket body 52 and the fixed fruit basket body 51 are provided with end baffles 553 at their respective ends.

[0030] This invention provides a base plate 551 at the lower end of the movable fruit basket 52 and side baffles 552 on both sides of the movable fruit basket 52. In practical use, when the opening / closing drive component 53 drives the movable fruit basket 52 to open, the base plate 551 and side baffles 552 move together with the movable fruit basket 52, ensuring that the fruit in the receiving basket 5 can reliably fall downwards, allowing all the fruit in the receiving basket 5 to be released without being retained inside. Simultaneously, when the opening / closing drive component 53 drives the movable fruit basket 52 to close, the base plate 551, side baffles 552, and end baffles 553 form a storage space to store the fruit picked by the cutting mechanism 3.

[0031] In some embodiments of the present invention, the fruit receiving basket 5 further includes an annular body 56, the upper end of the fixed fruit basket body 51 is fixedly connected to the annular body 56, the upper end of the movable fruit basket body 52 is rotatably connected to the annular body 56, and a receiving opening 561 is formed on the inner side of the annular body 56. The fruits cut and picked by the cutting mechanism 3 can fall into the fruit receiving basket 5 through the receiving opening 561.

[0032] In specific implementation of the present invention, in order to better connect the fixed fruit basket 51 and the movable fruit basket 52 to the annular body 56, L-shaped connecting plates 563 are provided on both sides of the annular body 56. The upper end of the fixed fruit basket 51 is fixedly connected to the L-shaped connecting plate 563, and the upper end of the movable fruit basket 52 is rotatably connected to the L-shaped connecting plate 563.

[0033] Furthermore, a guide plate 562 extends upward on the annular body 56 near the cutting mechanism 3. After the cutting mechanism 3 has finished harvesting the fruit, the guide plate 562 can be used to guide the fruit into the fruit receiving basket 5.

[0034] In some embodiments of the present invention, the harvesting attachment 100 further includes at least two tree-tightening mechanisms 8, which are located below the arc-shaped support body 1, and the upper end of the tree-tightening mechanism 8 is connected to the bottom of the arc-shaped support body 1. By arranging the tree-tightening mechanism 8 below the arc-shaped support body 1, the present invention ensures that, in practical use, the tree-tightening mechanism 8 can not only tighten the tree trunk, allowing the harvesting attachment 100 to hold the tree trunk tightly, thereby improving cutting stability, but also prevents interference between the tree-tightening mechanism 8, the cutting mechanism 3, and the fruit-receiving basket 5.

[0035] In some embodiments of the present invention, in order to enable the arc-shaped support body 1 to better engage with the fruit tree trunk and ensure that the two cutting mechanisms 3 can cover 360° of picking and cutting without dead angles, the arc-shaped support body 1 is an arc-shaped support body with an arc greater than or equal to 180° and less than or equal to 190°; the arc-shaped support body 1 is provided with fruit tree clamping mechanisms 8 at both ends below, and the two fruit tree clamping mechanisms 8 are spaced 180° apart to ensure that the picking attachment 100 can better hold the fruit tree trunk.

[0036] As one specific embodiment of the present invention, please refer to the following: Figure 8 As shown, the fruit tree tightening mechanism 8 includes an arc-shaped abutment 81, a swing arm 82, a fixed seat 83, and a first drive cylinder 84. The first drive cylinder 84 can be a pneumatic cylinder or a hydraulic cylinder. The fixed seat 83 is located at the bottom of the arc-shaped support body 1. The upper end of the swing arm 82 is rotatably connected to the fixed seat 83, so that the swing arm 82 can rotate relative to the fixed seat 83. The arc-shaped abutment 81 is connected to the lower end of the swing arm 82 and is located on the inner side of the swing arm 82. The first drive cylinder 84 is located on the outer side of the swing arm 82, and the upper end of the first drive cylinder 84 is hinged to the fixed seat 83, and the lower end of the first drive cylinder 84 is hinged to the swing arm 82. In the specific operation of the fruit tree clamping mechanism 8, when the first drive cylinder 84 extends forward, it can drive the swing arm 82 and the arc-shaped abutment 81 to move inward, so that the arc-shaped abutment 81 can clamp the fruit tree trunk; and when the first drive cylinder 84 retracts backward, it can drive the swing arm 82 and the arc-shaped abutment 81 to move outward, so that the arc-shaped abutment 81 can loosen the fruit tree trunk.

[0037] In some embodiments of the present invention, please refer to the following: Figure 7As shown, the cutting mechanism 3 includes a support base 31, a cutting tool 32, a rotating frame 33, a tool holder 34, a second drive cylinder 35, a third drive cylinder 36, and a fourth drive cylinder 37. The fruit basket connector 6 is connected to the support base 31. Specifically, the second drive cylinder 35, the third drive cylinder 36, and the fourth drive cylinder 37 can be cylinders or hydraulic cylinders. The inner wall of the arc-shaped support body 1 has an arc-shaped relief groove 12 formed along the circumferential direction. The arc-shaped relief groove 12 extends along the circumferential direction to both ends of the arc-shaped support body 1. The lower end of the support base 31 passes through the arc-shaped relief groove 12 and is connected to the arc-shaped track 2. The rotating frame 33 is rotatably connected to the support base 31. The second drive cylinder 35 is located between the support base 31 and the rotating frame 33. The second drive cylinder 35 drives the rotating frame 33 to rotate and adjust. The tool holder 34 is rotatably connected to the upper end of the rotating frame 33. The third drive cylinder 36 is located between the tool holder 34 and the rotating frame 33. The third drive cylinder 36 drives the tool holder 34 to swing inward and outward and adjust. The fourth drive cylinder 37 is located on the tool holder 34. The cutting tool 32 is connected to the movable end of the fourth drive cylinder 37. The fourth drive cylinder 37 drives the cutting tool 32 to cut. By adopting the above structural design of the cutting mechanism 3, in the specific use process, after the picking attachment 100 hugs the trunk of the fruit tree, the driving mechanism 4 can drive the arc track 2 to move the cutting mechanism 3 along the circumference to the required position. The second driving cylinder 35 can also drive the rotating frame 33 to rotate and adjust the cutting blade 32. The third driving cylinder 36 can also drive the blade support 34 to adjust the cutting blade 32 to swing inward and outward, so that the fourth driving cylinder 37 can drive the cutting blade 32 to accurately cut and pick the fruit.

[0038] In some embodiments of the present invention, please refer to the following: Figure 9 As shown, an arc-shaped movable channel 13 runs through the arc-shaped support body 1 along the circumferential direction. The arc-shaped track 2 is slidably assembled within the arc-shaped movable channel 13. Wear-resistant limiting plates 9 are provided at the top and bottom of the arc-shaped movable channel 13 for sliding contact with the arc-shaped track 2. The wear-resistant limiting plates 9 can be made of nylon. By providing wear-resistant limiting plates 9 at the top and bottom of the arc-shaped movable channel 13 and allowing the arc-shaped track 2 to directly slide in contact with the wear-resistant limiting plates 9, this invention effectively avoids vibration of the arc-shaped track 2 during movement, thereby improving the stability of the arc-shaped track 2, the cutting mechanism 3, and the receiving basket 5 during circumferential movement. Furthermore, because nylon has low frictional resistance, designing the wear-resistant limiting plates 9 as nylon limiting plates ensures smooth sliding of the arc-shaped track 2.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
