Description

Technical Field

[0001] This utility model belongs to the field of harvesting devices, specifically relating to a harvesting device for *Sapindus mukorossi* fruit. Background Technology

[0002] Traditional harvesting methods for *Xanthoceras sorbifolium* mainly involve knocking down branches or waiting for the fruit to fall naturally and then collecting it. However, knocking down branches causes a large number of healthy leaves to fall off, damaging the tree structure. While the natural fruit-falling method avoids damage to the tree, it is prone to problems such as seeds being eaten by birds and mold growth, and the labor cost for collection is relatively high. Currently, a harvester for fruits such as apples and pears has appeared on the market. After ripening, the fruit stalks of apples and pears easily separate from the branches. By pulling downwards with a handheld lever, the serrated ring applies downward force to the fruit, thus separating the fruit stalk from the branch. Furthermore, the appearance quality of the fruit is important, so it is necessary to retain the intact stalk. *Xanthoceras sorbifolium* branches are relatively brittle, especially in the later stages of fruit ripening when the branches are highly lignified. Pulling too hard can easily cause branch breakage or bark damage, affecting the tree's growth and fruiting ability the following year. Moreover, as a medicinal herb, the integrity of the fruit stalk is not a requirement for *Xanthoceras sorbifolium*. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the present invention provides a fruit-picking device for *Vernicia fordii*, which can cut the fruit to achieve rapid picking and effectively prevent the branches of the fruit tree from breaking or the bark from being damaged.

[0004] The specific technical solution adopted in this utility model is as follows:

[0005] A fruit-harvesting device for *Sapindus mukorossi* includes a handheld rod and a harvesting section located at the upper end of the handheld rod. The harvesting section has a ring-shaped structure, and a fruit-receiving bag for receiving fruits is located below the harvesting section. Crucially, the harvesting section includes a fixed ring and a movable ring coaxially mounted. The fixed ring has a set of fixed blades, and the movable ring has a set of movable blades. The fixed ring is fixedly connected to the handheld rod. The movable ring rotates around its own axis on the fixed ring by means of a drive assembly, causing the movable blades to form a shearing engagement with the fixed blades. The mounting end of the drive assembly is fixedly connected to the handheld rod.

[0006] The drive assembly includes a controller, a drive motor, a rotating shaft, and a button, all mounted on the handheld stick. The rotating shaft is connected to the drive shaft of the drive motor. The movable ring is fixed to one end of a pull rope, and the other end of the pull rope is wound around the rotating shaft. The controller is connected to the button and the drive motor. The controller receives a signal from the button and starts the drive motor. The rotating shaft, driven by the drive motor, winds up the pull rope, causing the movable ring to rotate around its own axis on the fixed ring.

[0007] A return spring is also provided between the movable ring and the hand handle. The movable ring is provided with a first pull ring, and the hand handle is provided with a second pull ring. The return spring is hooked to the first pull ring and the second pull ring respectively by means of hooks at both ends.

[0008] The movable ring is fitted inside the fixed ring. The movable ring has a protrusion for connecting with the pull rope. The fixed ring has a protrusion and a clearance hole for the first pull ring.

[0009] The feeding end of the fruit receiving bag is connected to the fixing ring.

[0010] The fruit-collecting bag has a funnel-shaped structure that is wider at the top and narrower at the bottom. The bottom of the fruit-collecting bag is open and extends downwards to the ground along the fixing ring.

[0011] The beneficial effects of this utility model are:

[0012] This invention changes the structure of the harvesting section, using a combination of fixed and movable blades for rotating shearing instead of the traditional method of knocking or pulling during harvesting. This avoids applying direct tension to the branches of the *Xanthoceras sorbifolium*, allowing for precise cutting of the fruit stalks without damaging the bark or causing breakage. This is beneficial for the tree's growth and ensures its ability to bear fruit the following year.

[0013] By sending a signal via a button, the controller controls the drive motor to achieve the cutting action of the movable and fixed blades. This eliminates the need to manually pull the rope, significantly reducing labor intensity and standardizing the cutting force. This avoids damage to branches caused by improper force during manual operation, ensuring the stability and safety of each harvesting action.

[0014] A return spring is installed between the movable ring and the hand handle. After one cutting action is completed, the movable ring rotates back to its original position under the action of the return spring, which facilitates the next cutting and harvesting. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0021] Specific implementation examples Figure 1 , Figure 2 As shown, this utility model relates to a fruit-picking device for *Sapindus mukorossi*, including a handheld rod 1 and a harvesting part 2 disposed at the upper end of the handheld rod 1. The harvesting part 2 has a ring-shaped structure, and a fruit-receiving bag 3 for receiving fruits is disposed below the harvesting part 2. The harvesting part 2 includes a fixed ring 4 and a movable ring 5 coaxially mounted. A set of fixed blades 6 is disposed on the fixed ring 4, and a set of movable blades 7 is disposed on the movable ring 5. The fixed ring 4 is fixedly connected to the handheld rod 1. The movable ring 5 rotates around its own axis on the fixed ring 4 by means of a drive component, and the movable blades 7 and the fixed blades 6 form a shearing engagement. The mounting end of the drive component is fixedly connected to the handheld rod 1.

[0022] This invention changes the structure of the harvesting part 2, and adopts the rotational shearing combination of fixed blade 6 and movable blade 7 to replace the traditional method of knocking or pulling for harvesting. This avoids applying direct pulling force to the branches of the Chinese tallow tree, and can accurately cut the fruit stalk without damaging the bark of the branch or causing the branch to break. This is beneficial to the growth of the tree and ensures the ability to bear fruit in the following year. Moreover, the harvesting device has a simple structure, is easy to operate, and can realize the rapid harvesting of Chinese tallow trees.

[0023] Initially, the movable blade 7 and the fixed blade 6 are separated. The movable ring 5 is driven to rotate by the drive assembly. The movable blade 7 on the movable ring 5 and the fixed blade 6 on the fixed ring 4 are separated and form an opening space. The worker holds the handle 1 of the harvesting device and aligns the harvesting part 2 with the branch where the target *Vernicia fordii* is located, so that the *Vernicia fordii* is located in the harvesting part 2. The fruit stalk or branch on the *Vernicia fordii* enters the opening space formed by the movable blade 7 and the fixed blade 6. The worker uses the drive assembly to drive the movable ring 5 to rotate on the fixed ring 4. The movable blade 7 and the fixed blade 6 work together to cut the fruit stalk or branch. The *Vernicia fordii* falls into the fruit collection bag 3 along the harvesting part 2 to complete the harvesting.

[0024] The movable ring 5 is fitted inside the fixed ring 4 to form a rotatable fit. Cover plates can be installed at the upper and lower ends of the fixed ring 4 to prevent the movable ring 5 from falling off the fixed ring 4. The cover plates are fixed to the fixed ring 4 with bolts.

[0025] The drive assembly includes a controller 8, a drive motor 9, a rotating shaft 10, and a button 11, all mounted on the handgrip 1. The rotating shaft 10 is connected to the drive shaft of the drive motor 9. The movable ring 5 is fixedly connected to one end of the pull rope 12. Figure 2 , Figure 3 As shown, the other end of the pull rope 12 is wound around the rotating shaft 10. The controller 8 is connected to the button 11 and the drive motor 9 respectively. The button 11 is installed at the lower end of the handheld lever 1. When the operator holds the lower end of the handheld lever 1 and presses the button 11, as shown... Figure 4 As shown, button 11 sends a signal to controller 8, controller 8 triggers drive motor 9 to start, drive motor 9 drives rotating shaft 10 to rotate, thereby realizing the winding of pull rope 12. Pull rope 12 generates tension on movable ring 5, causing movable ring 5 to rotate on fixed ring 4, thus realizing the harvesting of Sapindus mukorossi fruit.

[0026] The handheld lever 1 has an internal power supply for the controller 8 and the drive motor 9. The handheld lever 1 also has a main power switch. Turning on the main power switch enables the pressing of button 11 to send a signal to the controller 8 to perform a cutting action.

[0027] In this embodiment, the drive shaft of the drive motor 9 transmits power through a gear and a rotating shaft 10.

[0028] The shearing action of the movable blade 7 and the fixed blade 6 is achieved by controlling the drive motor 9 through the controller 8. There is no need to manually pull, which significantly reduces labor intensity and standardizes the shearing force, avoiding damage to branches caused by improper force during manual operation, and ensuring the stability and safety of each harvesting action.

[0029] The movable ring 5 is provided with a first pull ring 14, and the hand handle 1 is provided with a second pull ring 15. The return spring 13 is hooked and connected to the first pull ring 14 and the second pull ring 15 by means of hooks at both ends. The fixed ring 4 is provided with a protrusion 16 and a clearance hole for the first pull ring 14. The protrusion 16 and the first pull ring 14 extend out of the fixed ring 4 through their respective clearance holes. One end of the pull rope 12 is tied and connected to the protrusion 16, and the pull hook at one end of the return spring 13 is hooked on the first pull ring 14.

[0030] Preferably, the drive motor 9 is a servo motor or a servo motor. In this embodiment, the drive motor 9 is preferably a servo motor. By pressing the button 11 once, the controller 8 controls the drive motor 9 to complete a reciprocating motion of first rotating forward and then in reverse. The angles of the forward and reverse rotations are the same. When the drive motor 9 rotates forward, it winds up the pull rope 12. The rotating ring 5 realizes the cutting action of the movable blade 7. When the drive motor 9 rotates in reverse, the pull rope 12 unfolds from the rotating shaft 10 and pushes the movable ring 5 to reset under the action of the reset spring 13, thus realizing the reset action of the movable blade 7, which is convenient for the next harvest.

[0031] Preferably, the handheld lever 1 is a telescopic lever. In this embodiment, the drive motor 9, the rotating shaft 10, the harvesting part 2 and the return spring 13 are all set on the telescopic lever at the uppermost end of the handheld lever 1, and the controller 8 and the button 11 are installed on the handheld part at the lowermost end of the handheld lever 1.

[0032] The feeding end of the fruit receiving bag 3 is connected to the fixed ring 4. The fruit receiving bag 3 does not twist with the rotation of the movable ring 5. The fruit receiving bag 3 and the fixed ring 4 remain relatively stationary, which avoids the connection of the fruit receiving bag 3 from bearing torsional force, delays the wear of the fruit receiving bag 3, and thus improves the service life of the fruit receiving bag 3.

[0033] Preferably, the fruit-collecting bag 3 has a funnel-shaped structure, wider at the top and narrower at the bottom. The fruit-collecting bag 3 is a net bag with an opening at the bottom, and its lower end extends downwards along the fixing ring 4 to the ground. The longer fruit-collecting bag 3 can significantly increase the number of *Xanthoceras sorbifolium* fruits it can hold. This eliminates the need for repeated up-and-down movement of the harvesting section 2, allowing for the harvesting of multiple *Xanthoceras sorbifolium* fruits at once. The channel formed inside the fruit-collecting bag 3 gradually narrows, creating a flexible contact with the falling *Xanthoceras sorbifolium* fruits, causing them to fall slowly downwards and preventing them from crashing and breaking upon impact with the ground. The lower end of the fruit-collecting bag 3 can be placed inside a collection box, allowing the *Xanthoceras sorbifolium* fruits falling directly into the collection box for rapid fruit collection without the need for manual bending and picking.
