Description

Technical Field

[0001] This utility model relates to the field of fruit picking technology, specifically, to a fruit picking device. Background Technology

[0002] With the rapid development of the economy, agriculture, as my country's primary industry, is constantly progressing. Fruit tree planting, as an important part of agriculture, is also constantly developing. While fruit tree planting brings economic benefits to fruit farmers, the large volume of fruit harvesting makes fruit picking a heavy physical labor for them.

[0003] A search revealed that Chinese patent application CN218417403U discloses a fruit-harvesting device for fruit cultivation. This invention utilizes a vibrating motor that drives a connecting rod B to vibrate via a fixed cylinder. The connecting rod B, through a fixed frame, causes the tree trunk to vibrate. The violent shaking of the tree trunk causes cherries to fall onto a mesh bag, which then rolls through the mesh cylinder into a collection basket.

[0004] However, the following technical problems still exist when implementing the above-mentioned technical solutions: Because the fruits on fruit trees are often densely distributed and vary in size, vibration causes a large number of fruits to fall, which can easily lead to damage from mutual compression. Furthermore, the vibration can cause not only mature fruits to fall off, but also some immature or spoiled fruits. This not only increases the workload of subsequent screening and classification, but may also affect the overall quality of the fruit due to the mixing of immature or spoiled fruit.

[0005] Therefore, the urgent problem to be solved by this utility model is to provide a fruit picking device that can improve picking efficiency, avoid squeezing fruits together, and selectively pick ripe fruits during use. Utility Model Content

[0006] To address the aforementioned technical problems, the purpose of this utility model is to overcome the issues in the existing technology where fruits on fruit trees are often densely distributed and vary in size. When vibrating, as a large number of fruits fall, they are easily damaged by mutual compression. Furthermore, under the action of vibration, not only ripe fruits will fall off, but some unripe or spoiled fruits may also be shaken off. Therefore, this utility model provides a fruit picking device that can improve picking efficiency, avoid mutual compression between fruits, and selectively pick ripe fruits during use.

[0007] To achieve the above objectives, this utility model provides a fruit picking device, which includes: a handheld pole and a lifting rod that can move up and down vertically. The top of the lifting rod is fixedly fitted with a picking mechanism for manually controlling the picking of fruit.

[0033] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0034] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0035] Reference Figures 1-7 As shown, a fruit picking device includes: a handheld rod 100 and a lifting rod 102 that can be raised and lowered vertically. The top of the lifting rod 102 is provided with a picking mechanism 200 for manually controlling the picking of fruit via a fixing sleeve 103; wherein,

[0036] The circumferential surface of the lifting rod 102 is provided below the picking mechanism 200, and a collection component 300 is provided to buffer and collect the fallen fruit during picking. The hand handle 100 is provided with an adjustment mechanism 400 that can adjust the height of the lifting rod 102 according to the height of the picked fruit.

[0037] During use, the operator holds the hand lever 100 to ensure the overall stability of the harvesting device. Based on the height of the fruit to be harvested, the height of the lifting rod 102 is adjusted via the adjustment mechanism 400, allowing the harvesting mechanism 200 to accurately reach the fruit's location. The operator manually controls the harvesting mechanism 200 to harvest the target fruit using the hand lever 100. The harvested fruit falls naturally under gravity, first contacting the collecting component 300 located below the circumference of the lifting rod 102. The collecting component 300 is designed with cushioning properties to reduce the impact of the falling fruit and prevent damage. The collecting component 300 also serves a collection function, gathering the fallen fruit together for convenient subsequent processing and collection. If harvesting fruit at different heights is required, the operator can readjust the height of the lifting rod 102 via the adjustment mechanism 400.

[0038] Reference Figures 2-3 As shown, the harvesting mechanism 200 includes: a movable rod 201, a movable plate 205, a connecting rod 206, and a harvesting head 208; wherein, the movable rod 201 is slidably sleeved inside the fixed sleeve 103, the movable plate 205 is fixedly mounted at one end of the movable rod 201, the oppositely mounted rotating plate 207 is rotatably mounted on the mutually distant sides of the movable plate 205, the harvesting head 208 is fixedly mounted on the rotating plate 207, the connecting rod 206 is rotatably mounted on the side of the fixed sleeve 103 and its top end is rotatably connected to the rotating plate 207, and the movable rod 201 is provided with a driving component for driving the movable rod 201 to slide, thereby driving the rotating plate 207 to open and close for harvesting.

[0039] During harvesting, the operator holds the hand lever 100 and the lifting lever 102 to align the harvesting mechanism 200 with the target fruit. The operator pulls down the drive component to slide the movable lever 201. The sliding of the movable lever 201 is transmitted to the rotating plate 207 through the connecting rod 206, causing the rotating plate 207 to open around its rotation axis. The harvesting head 208 closes accordingly, ready to clamp or cut the fruit. When the harvesting head 208 contacts the fruit and successfully harvests it, the operator releases the drive component.

[0040] Reference Figures 2-6 As shown, the driving component includes: a pull rope 202, a pull ring 203, and a first spring 209; wherein, a fixing plate 204 is fixedly provided at the other end of the movable rod 201, a vertically downward pull rope 202 is fixedly provided on the circumferential surface of the fixing plate 204, a pull ring 203 is fixedly provided at the lower end of the pull rope 202, and a first spring 209 is also sleeved on the movable rod 201, with both ends abutting against the surface of the fixing sleeve 103 and the side of the movable plate 205 respectively.

[0041] In the above scheme, during harvesting, the operator pulls down the pull ring 203, and the pull rope 202 is pulled accordingly. The fixed plate 204 and the movable rod 201 slide together against the resistance of the first spring 209. The sliding of the movable rod 201 is transmitted to the rotating plate 207 through the connecting rod 206, causing the rotating plate 207 to open around its rotation axis. The harvesting head 208 closes accordingly, ready to clamp or cut the fruit. When the harvesting head 208 contacts the fruit and successfully harvests it, the operator releases the pull ring 203. Under the elastic force of the first spring 209, the movable rod 201 slides back to its original position. By adjusting the design of the connecting rod 206 and the rotating plate 207, the harvesting needs of fruits of different sizes and shapes can be adapted.

[0042] Reference Figures 2-7 As shown, the collection component 300 includes: a fixing ring 301, a receiving bag 302, and a collection bag 304; wherein, the side of the lifting rod 102 is fixedly provided with a fixing ring 301 below the rotating plate 207, the receiving bag 302 is fixedly sleeved inside the fixing ring 301, the bottom surface of the receiving bag 302 is fixedly provided with a guide bag 303 for buffering, and the collection bag 304 for collecting fruits is provided below the guide bag 303.

[0043] In the above scheme, after the picking mechanism 200 successfully picks the fruit, the fruit falls naturally under the action of gravity. The falling fruit first enters the receiving bag 302, and after being buffered by the guide bag 303, it finally falls into the collection bag 304. When the fruit in the collection bag 304 reaches a certain amount, the operator can stop picking, remove the collection bag 304 from under the guide bag 303, transfer the fruit to the storage container, and then place the empty or new collection bag 304 back under the guide bag 303 to continue the picking operation. The design of the guide bag 303 plays a buffering role, reducing the impact force when the fruit falls and protecting the integrity of the fruit.

[0044] Reference Figures 2-4 As shown, the adjustment mechanism 400 includes: a mounting box 401, a worm gear 402, and a worm 403; wherein, the top end of the hand handle 100 is fixedly provided with the mounting box 401, the lifting rod 102 is slidably sleeved in the mounting box 401, the side of the lifting rod 102 is fixedly provided with a rack 405, the mounting box 401 is rotatably provided with a worm gear 402 that meshes with the rack 405, and the mounting box 401 is rotatably provided with a worm 403 that meshes with the worm gear 402, and the top end of the worm 403 is fixedly provided with a throttle handle 404.

[0045] In the above scheme, when the height of the lifting rod 102 needs to be adjusted, the operator turns the handle 404. The rotation of the handle 404 drives the worm gear 403 to rotate, which in turn drives the worm wheel 402 to rotate. Since the worm wheel 402 meshes with the rack 405, the rotation of the worm wheel 402 drives the rack 405 and the lifting rod 102 to slide up and down along the mounting box 401, thereby achieving height adjustment. When the lifting rod 102 is adjusted to the desired height, the operator stops turning the handle 404. The height of the lifting rod 102 can be adjusted simply by turning the handle 404, meeting the harvesting needs of fruits at different heights.

[0046] Reference Figure 1 As shown, the throttle 404 is provided with a locking component 500 for locking the worm gear 403, thereby locking the height of the lifting rod 102.

[0047] In the above scheme, the design of the locking component 500 enables the lifting rod 102 to be firmly locked after being adjusted to the required height, preventing changes in the height of the lifting rod 102 due to external forces or vibrations, and enhancing the stability of the harvesting device.

[0048] Reference Figures 4-5 As shown, the locking assembly 500 includes: a slide rod 502, a limiting plate 503, and a second spring 504; wherein, a slide groove 501 is provided on the throttle 404, and the slide rod 502 slides through the slide groove 501; the top end of the slide rod 502 is fixedly provided with a limiting plate 503, and a second spring 504 is sleeved on it, with its two ends respectively abutting against the side of the throttle 404 and the side of the limiting plate 503; the surface of the mounting box 401 is provided with a limiting hole 505 that cooperates with the slide rod 502.

[0049] In the above scheme, after confirming that the lifting rod 102 has reached the required height, the operator holds the limiting plate 503 in the locking assembly 500 and moves the sliding rod 502 along the sliding groove 501 on the throttle 404. When the sliding rod 502 aligns with the limiting hole 505 on the surface of the mounting box 401, under the elastic force of the second spring 504, the sliding rod 502 will automatically spring into the limiting hole 505, thereby locking the worm gear 403 and thus locking the height of the lifting rod 102. The design of the locking assembly 500 ensures that the lifting rod 102 can be firmly locked after being adjusted to the required height, preventing changes in the height of the lifting rod 102 due to external forces or vibrations, and enhancing the stability of the harvesting device.

[0050] Reference Figure 5 As shown, the circumferential surface of the handheld lever 100 is provided with anti-slip grooves 101.

[0051] In the above solution, when the operator holds the harvesting device for harvesting, their fingers naturally rest in the anti-slip groove 101, increasing the stability and comfort of the grip. The design of the anti-slip groove 101 increases the friction between the handle 100 and the operator's fingers, preventing the harvesting device from slipping or becoming uncontrollable due to hand slippage, and improving the stability of the grip.

[0052] In summary, the fruit picking device provided by this utility model allows the operator to hold the handle 100 and rotate the worm gear 403 via the throttle 404. The worm gear 403 meshes with the worm wheel 402, causing the worm wheel 402 to rotate, which in turn drives the lifting rod 102 to slide within the mounting box 401 via the rack 405, thus adjusting the height of the lifting rod 102. After adjusting to a suitable height, the slide rod 502 slides along the slide groove 501, causing the limiting plate 503 to abut against the throttle 404, while the second spring 504 is compressed. When the slide bar 502 is aligned with the limiting hole 505 on the mounting box 401, the second spring 504 releases energy, pushing the limiting plate 503 and the slide bar 502 into the limiting hole 505, thereby locking the worm gear 403. The operator holds the picking device, aligns the picking head 208 with the fruit to be picked, and pulls down the pull ring 203. The pull rope 202 drives the fixed plate 204 and the movable rod 201 to slide within the fixed sleeve 103. The sliding of the movable rod 201 drives the rotating plate 207 to rotate via the connecting rod 206, causing the picking head 208 to close and clamp the fruit. After the fruit is clamped, the pull ring 203 is released, the first spring 209 releases energy, and pushes the movable plate 205 and the movable rod 201 to reset. At the same time, the rotating plate 207 and the picking head 208 also reset, picking the fruit off the branch. The picked fruit falls into the receiving bag 302 under the action of gravity. After being buffered by the guide bag 303, it finally falls into the collection bag 304. The operator can check the number of fruits in the collection bag 304 at any time. When the collection bag 304 is full or nearly full, the picking can be paused, the fruit in the collection bag 304 can be removed, and then the picking can continue. After all the fruits that need to be picked have been picked, the operator can rotate the worm gear 403 in the opposite direction through the throttle 404 to lower the lifting rod 102 to the lowest position for easy carrying and storage of the picking device.

[0053] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0054] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
