Description

Technical Field

[0001] This utility model relates to the field of fruit tree harvesting technology, specifically to a tool suitable for harvesting fruit from high places on fruit trees. Background Technology

[0002] Chicken heart fruit, also known as brocade crabapple, is a cultivated variety of the Rosaceae family and Malus genus. It is an economic fruit tree with both edible and ornamental value. The fruit is small and plump with a sweet taste and high market recognition. In recent years, the planting scale has continued to expand and the demand for harvesting is urgent. However, the fruiting parts of chicken heart fruit are uneven, distributed from the lower low branches to the upper tall branches, and harvesting the fruit from high places is a challenge for the industry.

[0003] Currently, the industry generally uses manual ladder picking. This method has the potential to tilt and tip over due to insufficient ladder stability, which can easily lead to people falling and getting injured, resulting in poor safety. Moreover, this method requires frequent movement and adjustment of the ladder to accommodate different fruit positions, which is not only cumbersome and time-consuming, but also physically demanding, making it unsuitable for long-term operations in large-scale orchards during their peak fruiting season.

[0004] To address the cumbersome, inefficient, and safety hazards of manual ladder-climbing fruit picking, various pole-type fruit pickers have emerged on the market, allowing people to harvest fruits from higher locations while remaining on the ground. However, most pole-type fruit pickers currently on the market have a fixed length structure. When picking fruits higher than the sum of the pole length and arm span, a ladder or stool is still required, failing to fundamentally solve the drawbacks of ladder-climbing. Secondly, when picking fruits below the pole length and out of reach of a person, the excessively long pole makes operation inconvenient, making it difficult to accurately control the picking position and angle, which not only reduces picking efficiency but also increases the risk of damaging the fruit.

[0020] The present invention will be further described in detail below with reference to embodiments: like Figures 1-5As shown, this utility model provides a tool suitable for picking fruit from high places on fruit trees, including a lower handle post 1 and an outer sleeve assembly 2 connected to one end of the lower handle post 1. An inner sleeve 3 is slidably disposed at the end of the outer sleeve assembly 2 away from the lower handle post 1. A picking component 4 for picking fruit is disposed at the end of the inner sleeve 3 away from the outer sleeve assembly 2. An adjustment component for driving the inner sleeve 3 to move along the axial direction of the outer sleeve assembly 2 is disposed inside the outer sleeve assembly 2. The adjustment component includes a dual-axis motor 6 disposed inside the outer sleeve assembly 2. The two output ends of the dual-axis motor 6 are respectively connected to a lead screw 7 and a connecting post 13. One end of the lead screw 7 is threadedly connected to the inner sleeve 3, and the connecting post 13... One end of the outer sleeve assembly 2 is equipped with a drive component, on which a winding wheel 9 is mounted. A suspension rope 8 is wound around the winding wheel 9. One end of the suspension rope 8 is connected to the harvesting component 4. The surface of the outer sleeve assembly 2 is equipped with a toggle component for pulling the suspension rope 8 and a control unit 26 for controlling the operation of the dual-axis motor 6. The control unit 26 includes a forward control button 22 and a reverse control button 23 electrically connected to the dual-axis motor 6. The toggle component includes a handle 19 fixedly connected to the outer sleeve assembly 2. A gripping rod 16 is slidably connected to the inner side of the handle 19. A T-shaped sleeve connecting bracket 15 for sleeved on the suspension rope 8 is fixedly connected to one side of the gripping rod 16. On the other side, multiple first springs 18 are fixedly connected to the inner side of the handle 19. The actuating assembly also includes anti-collision holes 21 opened on the surface of the outer tube assembly 2 and two limiting brackets 14 connected to the inner wall of the outer tube assembly 2. The two limiting brackets 14 are symmetrically arranged about the anti-collision holes 21 as the axis of symmetry, and the suspension rope 8 is located inside the two limiting brackets 14. The T-shaped sleeve connecting bracket 15 is located inside the anti-collision holes 21. Two corresponding sliding grooves 20 are opened on the inner side of the handle 19. The two ends of the grip rod 16 are slidably connected in the corresponding sliding grooves 20. When harvesting chicken heart fruit, the operator first holds the lower grip post 1 to maintain a stable grip, and then passes through The thumb presses the forward control button 22 or the reverse control button 23 on the control unit 26 to send a control signal according to the actual harvesting situation. At this time, the control signal will control the dual-axis motor 6 to start. One output end of the dual-axis motor 6 will drive the lead screw 7 to drive the thread transmission inside the inner sleeve 3, realizing the precise extension and retraction of the inner sleeve 3 along the axial direction of the outer sleeve assembly 2, so as to flexibly adapt to the harvesting needs of fruit trees of different heights. At the same time as the dual-axis motor 6 starts, the other output end of the dual-axis motor 6 will drive the connecting column 13 and the drive assembly to rotate, which in turn drives the winding wheel 9 on the drive assembly to rotate synchronously, completing the pretension adjustment of the suspension rope 8, so that the suspension rope 8 always maintains a certain pretension.

[0021] Furthermore, such as Figure 3 and Figure 5As shown, the drive assembly includes a worm gear 12 fixedly connected to one end of the connecting column 13. A worm wheel 11 meshes with the outer side of the worm gear 12. A rotating rod 10, which is rotatably connected to the lower grip column 1, is fixedly connected to the inner side of the worm wheel 11. The rotating rod 10 is fixedly connected to the take-up reel 9. When the dual-axis motor 6 drives the connecting column 13 to rotate, it will drive the worm gear 12 to rotate synchronously. At this time, through the meshing transmission between the worm gear 12 and the worm wheel 11, the worm wheel 11 can be driven to drive the rotating rod 10 fixedly connected to it to rotate. By rotating the rotating rod 10, the take-up reel 9 will be driven to rotate, thereby realizing the winding and unwinding operation of one end of the suspension rope 8, so that the suspension rope 8 always maintains a certain pretension.

[0022] Furthermore, such as Figure 1 , Figure 2 and Figure 3As shown, the harvesting component 4 includes a fixed frame 41 fixedly connected to one end of the inner sleeve 3. An elastic component is provided on one side of the fixed frame 41, and a drive frame 42 is fixedly connected to the upper end of the elastic component. One end of the suspension rope 8 is sleeved inside the elastic component and fixedly connected to the drive frame 42. Multiple pull rods 43 are rotatably connected to the outer side of the drive frame 42. The other ends of the multiple pull rods 43 are rotatably connected to rotating rods 44. One end of the rotating rod 44 is fixedly connected to a shearing head 45, and the other end of the rotating rod 44 is rotatably connected to the fixed frame 41. A collecting net sleeve 5 is fixedly connected to the inner side of the multiple shearing heads 45. A fruit conveying tube is fixedly connected to the lower end of the collecting net sleeve 5. The elastic component includes a sleeved on the outer side of the suspension rope 8. The telescopic column 24 on the side has a second spring 25 sleeved on its outer side. When the picking component 4 moves to the target fruit position and aligns with the fruit, the operator holds the handle 19 and presses the grip bar 16 with their fingers. The grip bar 16 slides smoothly along the slide groove 20 on the inner side of the handle 19, compressing multiple first springs 18 connected on one side. Through the T-shaped sleeve connecting frame 15 fixedly connected to the other side of the grip bar 16, the suspension rope 8 sleeved on it will be pulled synchronously. At this time, the suspension rope 8 will be pulled by the force, which will pull the drive frame 42 in the picking component 4 to move, thereby causing the drive frame 42 to compress the telescopic column 24 and the second spring 25. During the movement of the drive frame 42, the outer rotating connection will be driven. Multiple levers 43 are linked synchronously, pulling the rotating rod 44 to rotate around the fixed frame 41, thereby driving multiple shearing heads 45 at one end of the rotating rod 44 to close together, quickly completing the shearing operation of the fruit stem. The sheared fruit falls directly into the collection net 5, which is fixed inside the multiple shearing heads 45. At this time, under the action of gravity, the fruit in the collection net 5 will be transported through the fruit conveying tube connected at the lower end, thus causing the fruit to fall into the connecting collection device at the lower end. The collection device can be designed with a buffer component as needed to avoid damage to the fruit during the collection process. It should be noted that the multiple shearing heads 45 proposed in this solution include, but are not limited to, those shown in the figure. The three shear heads 45 are used in the process. When three shear heads 45 are used, the collecting net sleeve 5 will open in a triangular shape, which can be used to cover the chicken heart fruit, thus enabling subsequent harvesting. When four shear heads 45 are used, the collecting net sleeve 5 will open in a rectangular shape, which can also be used to cover large-diameter chicken heart fruit, thus enabling subsequent harvesting. Under the limiting action of two symmetrically arranged limiting frames 14, the suspension rope 8 smoothly passes through the anti-collision hole 21 on the surface of the outer tube assembly 2, effectively preventing the suspension rope 8 from shaking or wearing, and ensuring transmission stability.

[0023] Furthermore, after the harvest is completed, the operator releases the grip lever 16, and the first spring 18 resets under the elastic force, causing the grip lever 16 and the suspension rope 8 to return to their original positions simultaneously. At the same time, the second spring 25 also resets under the elastic force, which in turn pushes the drive frame 42, the pull rod 43 and the rotating rod 44 to reset in linkage, causing the shear head 45 to open automatically, ready for the next harvesting operation, thus completing a complete chicken heart fruit harvesting operation.

[0024] Furthermore, such as Figure 1 , Figure 2 As shown, the control unit 26 also includes a power supply box fixedly connected to the surface of the outer sleeve assembly 2, a circuit board and a battery module located inside the power supply box, and forward control button 22 and reverse control button 23 both electrically connected to the dual-axis motor 6 through the circuit board. The surface of the power supply box is provided with a charging port. When the operator operates the forward control button 22 or the reverse control button 23 according to the picking height requirement, the electrical signal triggered by the button will be processed by the circuit board inside the power supply box and accurately transmitted to the dual-axis motor 6 to realize the control of the rotation and start / stop of the dual-axis motor 6, thereby driving the lead screw 7 to extend and retract the inner sleeve 3 and drive the connecting column 13 to rotate in the forward and reverse directions. The charging port on the surface of the power supply box can replenish the battery module with power in time to ensure the continuous and stable operation of the equipment.

[0025] Furthermore, the dual-axis motor 6 in this solution is a device that can be purchased on the market by those skilled in the art. The device has not been structurally modified in this paper. Therefore, those skilled in the art are familiar with its working principle based on their professional knowledge and can apply it skillfully. Therefore, this paper will not elaborate on this point.

[0026] Furthermore, the circuit board, as a conventional device in this field, serves to receive and process the electrical signals transmitted by the forward control button 22 or the reverse control button 23, and then accurately transmit them to the dual-axis motor 6 to control its direction and start / stop. This technology is well-known to those skilled in the art and will not be elaborated upon further in this paper. Simultaneously, this solution aims to protect the physical structure, not the circuitry or software control. The description of the processing circuit in this paper is merely a supplementary explanation of the feasibility and authenticity of this invention; this invention does not seek protection for the algorithm and circuitry technology. It is worth emphasizing that although the electronic control program is not described in detail in this solution, those skilled in the art can understand and apply it based on their professional knowledge.

[0027] Furthermore, such as Figure 2As shown, the outer sleeve assembly 2 includes a first half sleeve 201 and a second half sleeve 202 detachably connected to the first half sleeve 201. Limiting blocks 204 are fixedly connected to the inner sides of both the first half sleeve 201 and the second half sleeve 202. The outer side of the inner sleeve 3 is provided with limiting grooves 203 corresponding to the two limiting blocks 204, and the limiting blocks 204 are slidably disposed inside the limiting grooves 203. Through the sliding cooperation between the limiting blocks 204 on the first half sleeve 201 and the second half sleeve 202 and the limiting grooves 203 on the outer side of the inner sleeve 3, the displacement of the inner sleeve 3 during extension and retraction can be effectively prevented. In addition, the outer sleeve assembly 2 adopts a structural design in which the first half sleeve 201 and the second half sleeve 202 are detachably connected. If it is necessary to inspect and maintain the internal dual-axis motor 6, lead screw 7 and other components, they can be easily disassembled and separated, improving the convenience of equipment maintenance.

[0028] Furthermore, such as Figure 1 As shown, an anti-slip sleeve is fixedly connected to the outer side of the lower grip column 1. The anti-slip sleeve design can improve the stability of the operator's hand when gripping the lower grip column 1.

[0029] The working principle of this tool, which is suitable for picking fruit from high places on fruit trees, will be explained in detail below.

[0030] like Figures 1-5 As shown, when harvesting chicken heart fruit, the operator first holds the lower handle post 1 with anti-slip sleeve to maintain a stable grip. Then, the operator presses the forward control button 22 or the reverse control button 23 on the control unit 26 with their thumb to send a control signal according to the actual harvesting situation. At this time, the control signal is transmitted to the dual-axis motor 6 through the circuit board in the power supply box. The battery module provides stable power support to the dual-axis motor 6, thereby realizing the output end of the dual-axis motor 6 driving the lead screw 7 to perform threaded transmission on the inner side of the inner sleeve 3. At this time, the limiting block 204 on the first half sleeve 201 and the second half sleeve 202 opens to the outside of the inner sleeve 3. The sliding fit of the limiting groove 203 can effectively prevent the inner sleeve 3 from shifting during extension and retraction, and realize the precise extension and retraction of the inner sleeve 3 along the axial direction of the outer sleeve assembly 2, so as to flexibly adapt to the harvesting needs of fruit trees of different heights. When the dual-axis motor 6 starts, the other output end of the dual-axis motor 6 will drive the connecting column 13 and the worm gear 12 to rotate synchronously. At this time, through the meshing transmission of the worm gear 12 and the worm wheel 11, the worm wheel 11 can drive the rotating rod 10 fixedly connected to it to rotate, and then drive the winding wheel 9 on the rotating rod 10 to rotate synchronously, so as to complete the pretension adjustment of the suspension rope 8 and keep the suspension rope 8 at a certain pretension.

[0031] Once the harvesting assembly 4 is moved to the target fruit position and aligned with the fruit, the operator grips the handle 19 and presses the grip lever 16 with their fingers. The grip lever 16 slides smoothly along the groove 20 on the inner side of the handle 19, simultaneously compressing multiple first springs 18 connected on one side. Through the T-shaped sleeve connecting frame 15 fixed on the other side of the grip lever 16, the suspension rope 8 sleeved on it is pulled synchronously. At this time, the force on the suspension rope 8 will pull the drive frame 42 in the harvesting assembly 4 to move, thereby causing the drive frame 42 to compress the telescopic column 24 and the second spring 25. During the movement of the drive frame 42, it drives multiple pull rods 43 connected to the outer side to move synchronously. The pull rods 43 pull the rotating rod 44 to rotate around the fixed frame 41, thereby driving the harvesting assembly 42 to move. Multiple shear heads 45 at one end of the rotating rod 44 close together to quickly complete the shearing of the fruit stem. The sheared fruit falls directly into the collection net 5, which is fixed inside the multiple shear heads 45. Under the action of gravity, the fruit in the collection net 5 will be transported through the fruit conveying tube connected at the lower end, thus causing the fruit to fall into the collection device connected at the lower end. The collection device can be designed with a buffer component as needed to prevent the fruit from being damaged during collection. The suspension rope 8 passes smoothly through the anti-collision hole 21 on the surface of the outer tube assembly 2 under the limiting action of two symmetrically arranged limiting frames 14, effectively preventing the suspension rope 8 from shaking or wearing, and ensuring transmission stability.

[0032] After harvesting, the operator releases the gripping rod 16, and the first spring 18 resets under elastic force, causing the gripping rod 16 and the suspension rope 8 to return to their original positions simultaneously. At the same time, the second spring 25 also resets under elastic force, which in turn pushes the drive frame 42, the pull rod 43, and the rotating rod 44 to reset in a coordinated manner, causing the shearing head 45 to open automatically, ready for the next harvesting operation, thus completing a complete chicken heart fruit harvesting operation. In addition, the outer sleeve assembly 2 adopts a structural design in which the first half sleeve 201 and the second half sleeve 202 are detachably connected. If it is necessary to inspect and maintain the internal dual-axis motor 6, lead screw 7, and other components, they can be easily disassembled and separated, improving the convenience of equipment maintenance.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
