Description

Technical Field

[0001] This utility model relates to the technical field of fruit picking equipment, specifically, to a fruit picker. Background Technology

[0002] Fruit harvesting is a difficult problem in orchard planting and production. In the existing technology, there are the following methods for fruit harvesting: First, combing the fruit with a comb. However, the size of the fruit is limited. Large fruits are not easy to pick. Moreover, the tools used for picking the fruit need to be at the appropriate angle and position, which has limitations.

[0003] The second method is fruit picking, but this method is limited to a single variety of fruits and is only suitable for shorter plants.

[0004] The third method is rake-style fruit picking. In this method, the person needs to stand at a suitable angle, which limits the size and shape of the fruit. It is not suitable for densely packed, small-diameter fruit.

[0005] The fourth method is picking fruit by grabbing. This method can only pick one fruit at a time, and the variety, size, and specifications of the fruit are limited. It requires precise positioning, high operational skills, and is relatively inefficient.

[0006] The fifth method is fruit picking. This method involves picking one or a bunch of fruits at a time. It requires precise positioning, and since there is no net bag to hold the fruit, they are prone to falling during the picking process.

[0007] A search revealed an electric fruit picker with announcement number CN116439013A. This picker has only one fruit-entry plane, and the inlet cannot be closed after the fruit is picked. The picking angle is limited. It is suitable for picking fruit from trees such as apple, pear, citrus, apricot, and peach. It uses electric shears to cut branches and fruit stems. However, it is limited by the variety, size, and specifications of the fruit, and the picking method also has certain limitations. The addition of a motor to the head increases its weight.

[0008] A high-altitude fruit-picking and branch-pruning device with announcement number CN218277862U has only one fruit-entry plane, which is limited to pruning fruit branches and fruit stalks, restricting the variety and size of fruit, and the fruit-picking method is singular.

[0009] A high-altitude fruit picker with announcement number CN218451176U uses a rake-type fruit picking method, with some teeth containing blades, and the fruit picking method is singular.

[0010] The rake-type fruit picking device with announcement number CN219373151U also has only one plane for fruit entry, which limits the picking angle and orientation, and restricts the variety, size and specifications of the fruit. Although it has a sealing plate, it is not very good.

[0011] A high-altitude fruit picker with announcement number CN220586895U is limited in fruit size and can only be used for large-diameter fruits, but the picking angle is limited.

[0012] The high-altitude fruit-picking device with announcement number CN221283827U has a single fruit-picking method. It can wrap the fruit when picking, but the angle and orientation are limited.

[0013] A type of high-altitude fruit picker with announcement number CN222382170U can only pick one fruit at a time, which limits the size of the fruit and results in low efficiency.

[0014] A high-altitude fruit picker with announcement number CN222707050U has limitations on the size of the fruit during picking, making the operation somewhat difficult, and the fruit stem can only be cut off when it enters the notch.

[0015] A high-altitude fruit-picking device, with announcement number CN221283827U, includes a support rod. The top of the support rod has a fixed U-shaped frame, and the end of the fixed U-shaped frame has a connecting frame. The two ends of the connecting frame are respectively hinged to a first movable frame and a second movable frame. The bottom of the support rod has a locking plate, which is hinged to the support rod via a rotating rod. The bottom of the locking plate has a handle. However, this fruit-picking device has a limited method; while it can wrap around the fruit, the angle and orientation are restricted, and the picker only has one fixed surface for picking. Since fruits can grow on branches in any direction (360 degrees), such as on the top or sides of branches, some pickers are difficult to use. Therefore, a fruit-picking device that is not limited by angle and orientation and facilitates fruit picking has been designed. Summary of the Invention

[0016] The technical problem to be solved by this utility model is to provide a fruit picker with a blade holder opening and closing component that provides two layout schemes: horizontal (first direction) and vertical (second direction), which are respectively adapted to the picking scenarios of low shrub fruits and high fruit tree fruits. This solves the problems of traditional pickers having a single scene and difficulty in picking from high / low places, and the picking angle is not limited. Even fruits growing on the side can be picked by this device.

[0017] A fruit harvester includes a support frame, which is a U-shaped frame with an opening in the middle of one side.

[0018] Furthermore, the cutting tool is L-shaped.

[0019] Furthermore, the cutting tool is one of a rake-tooth cutting tool, an acute-angle cutting tool, and a circular arc cutting tool;

[0020] The upper side of the rake blade is fixed with rake teeth extending in the direction away from the support frame. The rake teeth on the side corresponding to the connecting seat are inclined planes and can abut against each other when the blade holder swings and closes. The rake teeth can block the fruit, and the area between the rake teeth can accommodate the fruit stalk. When pulled, the rake teeth can block the fruit and pull the fruit down.

[0021] The upper edge of the acute-angled cutting tool and the vertical surface connected to the upper edge are both inclined surfaces, and the inclined surfaces converge inward into the support frame.

[0022] The upper edge L-shaped surface of the circular arc cutter has a circular arc protrusion, and the circumference of the circular arc protrusion is smaller than the circumference of the upper edge L-shaped surface of the circular arc cutter.

[0023] Furthermore, the tool holder opening and closing assembly includes a cantilever beam, the connecting seat is fixedly connected to the cantilever beam, the cantilever beam and the connecting seat are arranged along a first direction, the first direction being a direction parallel to the first surface of the connecting seat, the cantilever beam is fixedly connected to a gear frame, the two ends of the gear frame are respectively rotatably connected to the central shaft of a half gear, the half gear is respectively fixedly connected to one end of a rocker arm, the other end of each rocker arm is respectively fixedly connected to a connecting arm, each connecting arm is respectively fixedly connected to one end of the tool holder, and the half gear is connected to a drive assembly.

[0024] Furthermore, the tool holder opening and closing assembly includes a cantilever beam, and the connecting seat is fixedly connected to one end of the cantilever beam. The cantilever beam and the connecting seat are arranged along a second direction, which is a direction parallel to the second surface of the connecting seat. A gear frame is fixedly connected to the upper side of the other end of the cantilever beam. Half gears are rotatably connected to both ends of one side of the gear frame. The half gears are fixedly connected to a rocker arm. The other end of the rocker arm is rotatably connected to one end of the corresponding tool holder. The half gears are connected to a drive assembly.

[0025] Furthermore, the drive assembly includes a rack, a spring, a straight groove rod, a limiting post, a pull rope, a support rod, and a trigger. Both of the two half gears mesh with the rack. One end of the rack is fixedly connected to the straight groove rod. The groove of the straight groove rod is slidably connected to the limiting post. The limiting post is fixedly connected to the support rod. One end of the support rod is fixedly connected to the other end of the cantilever beam. The support rod is a hollow rod, and the straight groove rod is disposed within the support rod. The end of the gear carrier connected to the cantilever beam is semi-cylindrical. One end of the gear carrier and... The cavity of the support rod is connected, the straight groove rod passes through the semi-cylindrical end of the gear frame, the spring is provided in the semi-cylindrical area of ​​the cantilever beam, the straight groove rod passes through the spring, one end of the spring abuts against the limiting post, and the other end of the spring abuts against the rack. When the spring is not under force, the two tool holders are in the open state. The other end of the straight groove rod is fixedly connected to the pull rope, and the other end of the pull rope is fixedly connected to the trigger. One end of the trigger is rotatably connected to the other end of the support rod, and the trigger also has a fixed handle.

[0026] Furthermore, the pull rope is a steel wire rope.

[0027] Furthermore, a pressure plate is provided on the lower side of the tool holder, and the pressure plate and the tool holder are connected by screws. An edge of a guide bag is provided between the pressure plate and the tool holder, and the guide bag is fixed between the tool holder and the pressure plate by the screws. The pressure plate matches the shape of the tool holder.

[0028] Furthermore, it also includes a net bag, which is fixedly connected to the support frame. The width of the opening of the net bag is appropriate. After folding the edge inward or outward around the edge, it is sewn with thread to form a double-layered channel with openings at both ends. The support frame can pass through the channel, and the two ends of the support frame respectively protrude from the two ends of the channel.

[0029] Compared with the prior art, the advantages and positive effects of this utility model are:

[0030] The support frame and connecting seat are detachably connected by a snap-fit ​​structure with elastic buckles and hanging protrusions, which facilitates component replacement and maintenance. The blade holder opening and closing assembly provides two layout options, which are suitable for picking low-growing shrub fruits and high-growing fruit tree fruits respectively. This solves the problems of traditional pickers having limited scenarios and difficulty in picking from high / low places. Moreover, the picking angle is not limited, and even fruits growing on the side can be picked with this device.

[0031] The U-shaped symmetrical blade holder and hinged rotating connection design, together with the openable blade, can accommodate the entry and grabbing of fruits of different sizes. The blade adopts a design that extends away from the support frame and abuts against the inclined plane. When closed, it accurately cuts the fruit stem through planar shearing force, avoiding the damage caused by the squeezing of fruits by traditional harvesters. If the fruit stem is not cut off, the fruit is wrapped up and pulled, and the fruit falls into the net bag. Whether it is a single fruit or a bunch of fruits, regardless of variety, type and size, as long as it can be wrapped up, it can be picked.

[0032] The screw fixing structure of the knife holder and the pressure plate can stably clamp the guide bag, and together with the flexible collection space of the net bag, it can realize non-destructive operation throughout the entire process of picking, conveying and collecting.

[0033] The drive assembly utilizes a trigger, pull rope, rack and pinion, and half-gear linkage structure, along with an automatic spring reset function, to achieve rapid opening and closing control of the cutter holder: pulling the trigger drives the cutter holder to close for picking, and releasing it automatically resets the spring to open the cutter holder. This simple and labor-saving operation reduces hand fatigue during long-term work. The steel wire rope pull rope has high strength and wear-resistant properties, ensuring stable power transmission and extending the equipment's service life. The sliding fit between the limit post and the straight groove rod restricts the range of motion, ensuring operational safety and stability.

[0034] The guide bag is detachably fixed by pressure plate and screws, and the net bag is slidably connected to the support frame through holes, both of which can be quickly disassembled and installed, making it easy to clean, replace or upgrade; the fastening between the support frame and the connecting seat makes it easy to install and remove the net bag.

[0048] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0049] A fruit harvester includes a support frame 13, which is a U-shaped frame with an opening in the middle of one side. Elastic buckles 131 are fixedly installed at both ends of the opening side of the support frame 13, and each elastic buckle 131 is connected to a hanging protrusion. The hanging protrusion is fixed to both ends of one side of a connecting seat 15. The device also includes a blade holder 2, which is U-shaped and symmetrically arranged. The two ends of the blade holder 2 are rotatably connected by hinges 14. A blade 1 matching the shape of the blade holder 2 is fixedly connected to the inner side of each blade holder 2. The blade holder 2 is connected to a blade holder opening and closing assembly, which is connected to a drive assembly. The drive assembly drives the blade holder opening and closing assembly to open and close the two blade holders 2. The blade holder opening and closing assembly is connected to the connecting seat 15.

[0050] In this embodiment, the elastic buckle 131 and the buckling structure of the suspension protrusion realize the detachable connection between the support frame 13 and the connecting seat 15. The U-shaped symmetrical knife holder 2 is rotatably connected by the hinge 14 to form an openable and closable picking execution end. The shape of the knife 1 and the knife holder 2 are matched to ensure the integrity of the grasping action. The knife holder opening and closing component is linked with the drive component to realize the mechanically controlled opening and closing action.

[0051] The cutting tool 1 is L-shaped.

[0052] The cutting tool 1 is one of the following: a rake-tooth cutting tool 101, an acute-angle cutting tool 102, and a circular arc cutting tool 103;

[0053] The upper side of the rake blade 101 is fixed with rake teeth extending in a direction away from the support frame 13. The rake teeth on the side corresponding to the connecting seat 15 are inclined planes and can abut against each other when the blade holder 2 swings and closes. The rake teeth can block the fruit, and the area between the rake teeth can accommodate the fruit stem. When pulled, the rake teeth can block the fruit and pull the fruit down.

[0054] The upper edge of the acute-angled cutting tool 102 and the vertical surface connected to the upper edge are both inclined surfaces, and the inclined surfaces converge inward to the support frame 13.

[0055] The upper edge L-shaped surface of the arc-shaped cutter 103 is a circular arc protrusion, and the circumference of the circular arc protrusion is smaller than the circumference of the upper edge L-shaped surface of the arc-shaped cutter 103.

[0056] The rake teeth extend away from the support frame 13 to ensure that the blade can penetrate deep into the connection between the fruit and the branch during harvesting. The rake teeth on the side corresponding to the connecting seat 15 have an inclined plane. When closed, the fruit is blocked by the fruit-accommodating area formed by the plane abutting. The fruit stalk is in the gap between the rake teeth. The fruit can be moved by pulling this device. Under the action of the pulling force, the fruit stalk is broken and the fruit falls into the area formed by the rake teeth. Furthermore, the extension length of the rake teeth and the spacing between the rake teeth can be set as needed to adapt to different fruits, such as single fruits such as apples, pears, pomegranates, plums, peaches, etc.; a bunch of fruits such as hawthorns, wild apples, etc. The rake teeth of the blade 1 can be a flat tooth, an arc tooth, or a multi-toothed blade formed by multiple teeth. Multi-toothed blades are convenient for harvesting a bunch or a cluster of fruits.

[0057] When the blade 1 is an acute-angle blade 102, its inclined surface design allows for the formation of a gradually tightening acute-angle space during the closing of the blade holder 2. This structure allows for precise contact between the fruit and the stem during harvesting using the inclined surface. As the blade holder 2 closes, the acute-angle portion applies concentrated force to the stem, thereby quickly and smoothly pinching or cutting off the stem. Simultaneously, since the upper edge and vertical surface are inclined surfaces that converge inward towards the support frame 13, a good wrapping effect is achieved after grasping the fruit, reducing the possibility of the fruit falling. This acute-angle blade 102 is particularly suitable for fruits with relatively thin stems and moderate toughness, such as cherries, grapes (single berries), and cherry tomatoes, ensuring harvesting efficiency while avoiding damage to the fruit due to excessive force.

[0058] When the blade 1 is an arc-shaped blade 103, the arc-shaped protrusion on its upper L-shaped surface plays a key role. During the harvesting process, the arc-shaped protrusion can form a gentle contact with the fruit surface, avoiding squeezing or scratching the fruit. Since the circumference of the arc-shaped protrusion is smaller than the circumference of the upper L-shaped surface, the protrusion can preferentially contact the fruit stem when the blade holder 2 is closed. For some fruits with a more rounded shape and more fragile skin, such as oranges, tangerines, kiwis, and red dates, the arc-shaped blade 103 can provide a gentler harvesting action and effectively protect the integrity of the fruit.

[0059] The tool holder opening and closing assembly includes a cantilever beam 9, and a connecting seat 15 is fixedly connected to the cantilever beam 9. The cantilever beam 9 and the connecting seat 15 are arranged along a first direction, which is a direction parallel to the first surface 151 of the connecting seat. The cantilever beam 9 is fixedly connected to a gear frame 7. The two ends of the gear frame 7 are respectively rotatably connected to the central shaft of a half gear 17. The half gear 17 is respectively fixedly connected to one end of a rocker arm 6. The other end of each rocker arm 6 is respectively fixedly connected to a connecting arm 5. Each connecting arm 5 is respectively fixedly connected to one end of the tool holder 2. The half gear 17 is connected to a drive assembly.

[0060] In this embodiment, the opening and closing of the knife holder 2 is achieved through a transmission structure in the first direction. The cantilever beam 9 and the connecting seat 15 are arranged in the horizontal direction. The half gears 17 at both ends of the gear frame 7 are rigidly connected to the knife holder 2 through the swing rod 6 and the connecting arm 5. When the half gear 17 rotates, the swing rod 6 drives the connecting arm 5 and the knife holder 2 to swing around the hinge 14 to achieve the opening and closing action. The horizontal layout is suitable for picking low or horizontally growing fruits such as shrub fruits. The rigid transmission ensures that the opening and closing angle of the knife holder 2 is stable and improves the accuracy of operation.

[0061] The tool holder opening and closing assembly includes a cantilever beam 9, and a connecting seat 15 is fixedly connected to the top end of the cantilever beam 9. The cantilever beam 9 and the connecting seat 15 are arranged along a second direction, which is parallel to the second surface 152 of the connecting seat. A gear frame 7 is fixedly connected to the upper side of the other end of the cantilever beam 9. Half gears 17 are rotatably connected to both ends of one side of the gear frame 7. The half gears 17 are fixedly connected to a rocker arm 6. The other end of the rocker arm 6 is rotatably connected to one end of the corresponding tool holder 2. The half gears 17 are connected to a drive assembly.

[0062] In other embodiments, the opening and closing of the blade holder 2 is achieved through a transmission structure in the second direction. The cantilever beam 9 and the connecting seat 15 are arranged in the vertical direction. The gear frame 7 is located at the top of the cantilever beam 9. The half gear 17 is rotatably connected to the blade holder 2 through the swing rod 6. When the half gear 17 rotates, the swing rod 6 drives the blade holder 2 to swing up and down to achieve opening and closing. The vertical layout is suitable for fruit picking scenarios that are high up or growing vertically (if the fruit is high up on the tree). The rotational connection reduces the space occupied in the vertical direction and improves the scene adaptability of the harvester.

[0063] The drive assembly includes a rack 18, a spring 19, a straight groove rod 20, a limiting post 21, a pull rope, a support rod 10, and a trigger 12. Both of the two half-gears 17 mesh with the rack 18. One end of the rack 18 is fixedly connected to the straight groove rod 20. The groove of the straight groove rod 20 is slidably connected to the limiting post 21. The limiting post 21 is fixedly connected to the support rod 10. One end of the support rod 10 is fixedly connected to the other end of the cantilever beam 9. The support rod 10 is a hollow rod, and the straight groove rod 20 is disposed within the support rod 10. One end of the gear frame 7 connected to the cantilever beam 9 is semi-cylindrical. The straight groove rod 20 is connected to the cavity of the support rod 10. The straight groove rod 20 passes through the cylindrical end of the gear frame 7. The spring 19 is provided in the cylindrical area of ​​the cantilever beam 9. The straight groove rod 20 passes through the spring 19. One end of the spring 19 abuts against the limiting post 21, and the other end of the spring 19 abuts against the rack 18. When the spring 19 is not under force, the two tool holders 2 are in the open state. The other end of the straight groove rod 20 is fixedly connected to the pull rope. The other end of the pull rope is fixedly connected to the trigger 12. One end of the trigger 12 is rotatably connected to the other end of the support rod 10. The trigger 12 is also fixed with a handle 11.

[0064] In this embodiment, the trigger 12 pulls the rope, which drives the straight groove rod 20 and the rack 18 to move. The rack 18 meshes with the half gear 17 to make it rotate, thereby driving the tool holder 2 to close. After the tension is released, the spring 19 resets and pushes the rack 18 to move in the opposite direction, so that the tool holder 2 opens. The limit post 21 cooperates with the straight groove rod 20 to ensure transmission stability. The opening and closing of the tool holder 2 is controlled by the manual trigger 12, and the reset of the spring 19 reduces the operating intensity.

[0065] When the spring 19 is not under stress, the two blade holders 2 are in the open position, making it easy to align with the fruit. The operator holds the handle 11 and pulls the trigger 12. The trigger 12 drives the straight groove rod 20 to slide within the cavity of the support rod 10 via the pull rope. The straight groove rod 20 drives the rack 18 to move. The rack 18 meshes with the half gear 17, driving the half gear 17 to rotate. The half gear 17 is fixedly connected to the swing rod 6. The other end of the swing rod 6 is fixedly connected to the connecting arm 5. The connecting arm 5 is connected to the blade holder 2. Therefore, the rotation of the half gear 17 drives the blade holder 2 to swing and close through the swing rod 6 and the connecting arm 5, thereby cutting or clamping the fruit stem for harvesting. After releasing the trigger 12, under the action of the spring 19, the spring 19 pushes the rack 18 to return to its original position. The rack 18 drives the half gear 17 to rotate in the opposite direction, causing the blade holder 2 to open again through the swing rod 6 and the connecting arm 5, returning to the initial state, preparing for the next harvest. Throughout the process, the limiting post 21 is used to limit the sliding range of the straight groove rod 20 to ensure the stability of the mechanism's movement.

[0066] The pull rope is a steel wire rope 22. The steel wire rope 22 has the characteristics of high strength, wear resistance and low elongation, which solves the problems of easy breakage and tensile deformation of traditional ropes, ensures that the pull rope can stably transmit power during repeated pulling, and extends the service life of the drive components.

[0067] A pressure plate 24 is provided on the lower side of the tool holder 2. The pressure plate 24 and the tool holder 2 are connected by screws. The edge of a guide bag is provided between the pressure plate 24 and the tool holder 2. The guide bag is fixed between the tool holder 2 and the pressure plate 24 by the screws. The pressure plate 24 matches the shape of the tool holder 2.

[0068] The guide bag can be detached and installed by means of the fixing structure of the pressure plate 24 and screws, which solves the problem of collecting and guiding the fruit after harvesting. The edge of the guide bag is clamped and fixed between the knife holder 2 and the pressure plate 24 to ensure that the fruit can enter the guide bag when it falls from the knife holder 2, avoiding direct fall damage to the fruit; the detachable design makes it easy to replace and clean the guide bag.

[0069] The guide bag is made of a soft material and can be a cylindrical channel with open ends, formed by a cloth. The soft material (such as cloth) prevents the fruit from colliding with the hard shell parts and causing damage; the cylindrical channel with open ends ensures that the fruit can slide smoothly from the picking end to the collecting end, solving the problem of fruit getting stuck and falling off in traditional harvesters, and improving fruit collection efficiency.

[0070] It also includes a net bag 4, which is fixedly connected to the support frame 13. The width of the opening of the net bag 4 is appropriate. After folding the edge inward or outward around the opening, it is sewn with thread to form a double-layered channel with openings at both ends. The support frame 13 can pass through the channel, and the two ends of the support frame 13 respectively protrude from the two ends of the channel.

[0071] The net bag 4 serves as the final fruit collection container. Through the folded edge stitching, the hole forms a sliding fit with the support frame 13, enabling quick installation and disassembly. The flexible structure of the net bag 4 can accommodate multiple fruits, and the width of the bag opening is adapted to the support frame 13, ensuring that all fruits falling from the guide bag can enter the net bag 4, completing the closed loop of picking and collection.

[0072] The bottom of the net bag 4 is movable, and the closed opening at the bottom can be opened.

[0073] The method of using this utility model is as follows:

[0074] Preferably, the rake-tooth blade 101 is selected as the blade used during harvesting;

[0075] Method 1: Select the knife holder opening and closing assembly arranged along the first direction. Clamp the edge of the guide bag between the lower side of the knife holder 2 and the pressure plate 24, and fix it with screws. Let the opening of the guide bag extend horizontally and hang down naturally, ensuring that the fruit can slide down the path from horizontal to vertical after picking. Pass the support frame 13 through the hole of the net bag 4, and adjust the position of the net bag 4 so that it is below the support frame 13, with the bag opening facing the guide bag outlet, which is suitable for the short-distance collection needs of low-lying fruits. Connect the elastic buckle 131 on the opening side of the support frame 13 to the hanging protrusion of the connecting seat 15. Hold the handle 11 and pull the U The blade holder 2 is aligned with low shrubs or horizontally growing fruits, allowing the fruit to enter between the two blades 1 through the opening of the support frame 13. Pulling the trigger 12 pulls the rope, causing the straight groove rod 20 to slide horizontally along the cavity of the support rod 10. The rack 18 meshes with the half gear 17 and rotates. The swing arm 6 drives the blade holder 2 to close horizontally through the connecting arm 5. The inclined plane of the rake teeth abuts against the fruit, and the fruit stem is naturally located in the area between the rake teeth or between the rake teeth. The rake teeth block the fruit, keeping the blade holder 2 in a closed state. Pulling the device moves the fruit, causing it to be pulled and the fruit stem to break off, thus picking the fruit. The fruit falls into the horizontally extending guide bag and slides into the lower net bag 4 along the soft channel. After releasing the trigger 12, the spring 19 pushes the rack 18 to return to its original position, and the blade holder 2 opens horizontally, ready for the next horizontal alignment and picking.

[0076] Method 2: Select the blade holder opening and closing assembly arranged along the second direction, fix the guide bag vertically along the blade holder 2, align the opening with the upper picking area of ​​the blade holder 2, and let the other end hang vertically downwards. Utilize gravity to improve fruit conveying efficiency, adapting to the vertical drop requirements of fruits from high places. After the support frame 13 passes through the holes of the net bag 4, adjust the net bag 4 to a vertical position below the support frame 13, ensuring the bag opening completely covers the guide bag outlet, ensuring all fruits falling from high places enter the net bag 4. Fasten the elastic buckle 131, hold the handle 11 and raise the device, placing the U... The shaped knife holder 2 is aligned with the fruit on the high fruit tree from below, allowing the fruit to enter the knife holder 2 through the opening of the support frame 13, and then between the two knives 1. Pulling the trigger 12 causes the rope to slide vertically along the straight groove rod 20, causing the rack 18 to mesh with the half gear 17 and rotate. The swing rod 6 drives the knife holder 2 to close up and down, with the inclined plane of the rake teeth abutting against the fruit. The fruit stem is naturally located in the area between the rake teeth or between the rake teeth, and the rake teeth block the fruit. Keeping the knife holder 2 in a closed state, pulling the device moves the fruit, causing the fruit stem to be pulled off and separated from the branch. The fruit is then picked and slides quickly down the vertical guide bag to the net bag 4 below. After releasing the trigger 12, the spring 19 pushes the rack 18 to return to its vertical position, and the knife holder 2 opens up and down, allowing it to be raised directly to aim at the next high fruit.

[0077] This utility model also discloses a method for using a fruit harvester, including the following steps:

[0078] Step 1: Select the appropriate tool 1 according to the type of fruit to be picked: If picking a single fruit (such as apple, pear) or a bunch of fruit (such as hawthorn), select the rake tooth tool 101. The extension length and spacing of the rake teeth can be adjusted according to the size of the fruit. The multi-tooth tool 1 is suitable for picking a bunch of fruit; if picking fruit with thin stems and moderate toughness (such as cherry, grape, single fruit), select the acute angle tool 102; if picking fruit with round shape and fragile skin (such as orange, tangerine, kiwi, red date), select the arc tool 103.

[0079] Choose the opening and closing direction of the knife holder 2 according to the fruit growth scene. When picking low shrubs or horizontally growing fruits, select the opening and closing direction of the knife holder 2 arranged along the first direction (the horizontal direction parallel to the first surface 151 of the connecting seat); when picking high or vertically growing fruits (if the fruit is high up on the tree), select the opening and closing direction of the knife holder 2 arranged along the second direction (the vertical direction parallel to the second surface 152 of the connecting seat).

[0080] Step 2: Install the cutter 1. After installation, install the guide bag 23. Clamp the edge of the guide bag 23 between the lower side of the cutter holder 2 and the pressure plate 24, and fix it with screws to ensure that the guide bag 23 is installed firmly.

[0081] If the tool holder 2 opening and closing assembly arranged in the first direction is selected, the guide bag 23 will extend horizontally and then hang down naturally.

[0082] If the second-direction knife holder 2 opening and closing assembly is selected, the guide bag 23 is fixed along the vertical direction of the knife holder 2, with the opening aligned with the upper picking area of ​​the knife holder 2 and the other end hanging vertically downwards.

[0083] Next, install the net bag 4. Pass the support frame 13 through the hole formed by the folded and sewn edge of the net bag 4. Adjust the position of the net bag 4 so that it is below the support frame 13 and the opening of the bag is directly opposite the outlet of the guide bag 23. Ensure that both ends of the support frame 13 pass through the two ends of the hole respectively.

[0084] Step 3: Harvest the fruit using the installed harvester:

[0085] If the rake tooth blade 101 is used: the inclined plane of the rake tooth abuts against the fruit, the fruit stem is naturally located in the area between the rake teeth or between the rake teeth, the rake teeth block the fruit, and the device is pulled while the blade holder 2 is in a closed state. The fruit stem is pulled off and the fruit is picked.

[0086] If an acute-angled blade 102 is used: during the closing process of the blade holder 2, the inclined surface forms a gradually tightening acute-angle space, which precisely fits the connection between the fruit and the stem. The acute-angled part applies a concentrated force to the stem, pinching or cutting off the stem. At the same time, the inclined surface forms a wrapping effect to reduce fruit falling.

[0087] If using the arc-shaped blade 103: the arc-shaped protrusion makes gentle contact with the fruit surface, and when closed, the protrusion first contacts the fruit stem, achieving gentle picking and avoiding fruit squeezing or scratching.

[0088] Step 4: Fruit Removal: Once a certain number of fruits have been collected in net bag 4, open the bottom of net bag 4 and pour out the fruits.

[0089] The above-disclosed embodiments are merely specific examples of this utility model. However, this utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
