Abstract
Description
Technical Field
[0001] This utility model relates to the field of harvesting technology, and more specifically, to a retractable olive fruit harvesting rake. Background Technology
[0002] Olive is one of the world's four major woody oilseed tree species. The oil extracted from its fresh fruit is rich in nutrients and active ingredients. When harvesting fresh olives, harvesting tools are needed to pick the fruit.
[0003] Currently, the tools used for harvesting fresh olives are manual harvesting or mechanical / semi-mechanized harvesting equipment. Mechanized harvesting is highly efficient, but the equipment cost is too high and it is only suitable for large-scale commercial planting. Small-scale planting mostly uses manual harvesting rakes (harvesting combs).
[0004] The existing harvesting rake mainly consists of a comb head and a row of comb teeth arranged side by side on the comb head. Because the spacing between the traditional comb teeth is fixed, it is easy to get stuck on branches with irregular paths when it moves. If too much pulling force is added, it will cause damage to the branches and leaves when the fresh olives are picked.
[0005] In view of this, this paper studies and improves the existing structure and its shortcomings, and provides a retractable olive fruit harvesting rake in order to achieve a more practical purpose. Summary of the Invention
[0006] To overcome the shortcomings mentioned above, this utility model provides a retractable olive fruit harvesting rake, which solves the problem that the fixed spacing of the comb teeth of the harvesting rake leads to obstructed movement, inconvenient harvesting, and easy damage to the fresh fruit.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a retractable olive fruit harvesting rake for harvesting fresh olives, comprising multiple rake plates connected in sequence, one of which is provided with a combined rod, each rake plate is provided with a pair of flexible connecting components, and each flexible connecting component is provided with rake teeth.
[0008] In a preferred embodiment, a positioning block is fixedly connected to one end of the rake plate, and a positioning groove is fixedly connected to the other end of the rake plate. The positioning block and the positioning groove are interlocked, and one rake plate is connected to the positioning block on the other rake plate by bolts.
[0009] In a preferred embodiment, the combined rod body includes a carbon fiber rod one and a carbon fiber rod two that are threaded together. An internal thread head is fixedly connected to the front side of the rake plate, and one end of the carbon fiber rod one is threaded to the internal thread head.
[0010] In a preferred embodiment, the outer surface of the carbon fiber rod is fitted with an anti-slip sleeve.
[0011] In a preferred embodiment, the flexible connecting assembly includes a first fixing block, a hollow tube fixedly connected to the first fixing block, a rotating rod rotatably connected to the bottom of the hollow tube, a second fixing block rotatably connected to the outer side of the rotating rod, both the first fixing block and the second fixing block being fixedly connected to the back of the rake plate, a column fixedly connected to one end of the rotating rod, the column being located inside the hollow tube, a torsion spring sleeved on the column, the two ends of the torsion spring being fixedly connected to the column and the hollow tube respectively, a connecting block fixedly connected to the outer surface of the rotating rod, and the rake teeth fixedly connected to one end of the connecting block.
[0012] In a preferred embodiment, the rake teeth are arranged at an angle, and a "V" shaped groove is formed between adjacent rake teeth.
[0013] In a preferred embodiment, one side of the rake teeth is rounded, and one side of the rake teeth is covered with a silicone pad.
[0014] In a preferred embodiment, a fixing rod is fixedly connected to the rake plate, and a guide plate is fixedly connected to one end of the fixing rod. The guide plate is located below the adjacent rake teeth.
[0015] The technical effects and advantages of this utility model are as follows: The retractable olive fruit harvesting rake features a pair of rake teeth on the rake plate. These teeth are movably connected via corresponding flexible connecting components. As the rake teeth lower the olive fruit along the branch, the resistance of the branch causes adjacent rake teeth to rotate relative to each other, widening the distance between them. This accommodates different branch diameters, preventing branch breakage from forceful pulling, thus protecting both the fruit and the tree. Multiple rake plates can be combined and connected via corresponding positioning grooves, positioning slots, and bolts, allowing for convenient assembly and flexible adjustment of the number of rake teeth. The retractable rod and multiple rake plates adapt to branches of varying heights, reducing the need for climbing. The "V"-shaped groove rake teeth naturally form a guide channel when the fruit is removed, allowing it to fall along the V-shaped groove and the slope of the rake plate, thus concentrating harvesting, increasing fruit capture rate, and reducing the possibility of missed harvests. The branch guide plate separates branches and leaves from the fruit, improving the efficiency of subsequent sorting. Furthermore, the components of this invention are connected by detachable joints such as threads and plugs, allowing for quick replacement of damaged individual rake teeth, rake plates, or rods, thus reducing maintenance costs. Additionally, this invention can also be applied to the harvesting of fruits from other similar tree species. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] See also Figures 1-5 This utility model provides a retractable olive fruit harvesting rake for harvesting fresh olives. It includes multiple rake plates 1 connected in sequence. One end of the rake plate 1 is fixedly connected to a positioning block 13, and the other end of the rake plate 1 is fixedly connected to a positioning groove 14. The positioning block 13 and the positioning groove 14 are connected by plug-in. One rake plate 1 is connected to the positioning block 13 on another rake plate 1 by bolts. One or two bolts can be set as needed.
[0021] In use, adjacent rake plates 1 can be connected by the corresponding positioning block 13 and positioning groove 14. One end of the subsequent bolt can pass through the top of the rake plate 1 and enter the positioning groove 14. Then, one end of the bolt can be threaded into the threaded hole at the top of the positioning block 13. This locks the adjacent rake plates 1, satisfying the convenient need for assembling multiple rake plates 1 in sequence.
[0022] Among them, a combined rod body is provided on the middle rake plate 1. The combined rod body includes carbon fiber rod 1 2 and carbon fiber rod 2 3 that are threadedly connected to each other. An internal thread head 11 is fixedly connected to the front of the rake plate 1, and one end of carbon fiber rod 1 2 is threadedly connected to the internal thread head 11.
[0023] In this embodiment, the outer surface of the carbon fiber rod 2 3 is covered with an anti-slip sleeve 12, and the outer surface of the carbon fiber rod 1 2 can also be covered with an anti-slip sleeve 12.
[0024] The carbon fiber rod 2 3 with anti-slip sleeve 12 is located at the very end of the combined rod body. The anti-slip sleeve 12 can improve the grip anti-slip ability.
[0025] The internal thread head 11 is fixedly connected to the rake plate 1 located in the middle. The threaded connection between the carbon fiber rod 12 and the internal thread head 11 facilitates assembly. In this application, the length of both the carbon fiber rod 12 and the carbon fiber rod 23 is at least one meter. The number of carbon fiber rod 23 can be one or two depending on the harvesting height of the olive tree, so as to meet the requirements of the extension and shortening of the harvesting height of the rake plate 1.
[0026] In this embodiment: Each rake plate 1 is equipped with a pair of flexible connecting components. Each flexible connecting component includes a fixing block 4, on which a hollow tube 5 is fixedly connected. A rotating rod 6 is rotatably connected to the bottom of the hollow tube 5. A fixing block 7 is rotatably connected to the outer side of the rotating rod 6. Both fixing blocks 4 and 7 are fixedly connected to the back of the rake plate 1. A column 8 is fixedly connected to one end of the rotating rod 6. The column 8 is located inside the hollow tube 5. A torsion spring 9 is sleeved on the column 8. Both ends of the torsion spring 9 are fixedly connected to the column 8 and the hollow tube 5, respectively. A connecting block 15 is fixedly connected to the outer surface of the rotating rod 6. Each flexible connecting component is equipped with rake teeth 10, which are fixedly connected to one end of the connecting block 15. It should be noted that the flexible connecting components cannot be replaced by a simpler torsion hinge, as this would not produce the spring-like deformation and rebound effect.
[0027] Each rake plate 1 is equipped with a pair of rake teeth 10, which are located on the back of the rake plate 1. The initial state of the rake teeth 10 is as follows: one side of the rake teeth 10 is tightly against the back of the rake plate 1, and a gap is provided between the rake teeth 10. This gap allows for the removal of fresh olives growing along the branch path and through the fruit stalk. In this application, the stiffness coefficient of the torsion spring 9 is 0.8-1.2 N / mm. When the rake teeth 10 are subjected to a force greater than 10 N, the torsion spring 9 can deform. In use, by moving adjacent rake plates 1 to the outside of the branch, the combined rod provides tension, allowing the pair of rake teeth 10 to remove the fresh olives along the branch path. When the rake teeth 10 encounter resistance greater than 10 N from irregularly shaped branches... At this time, the rake teeth 10 can drive the rotating rod 6 to rotate through the connecting block 15. The rotating rod 6 can drive the column 8 to rotate inside the hollow tube 5. The rotation of the column 8 can cause the torsion spring 9 to deform, so that the rake teeth 10 can be opened adaptively. When the rake teeth 10 are opened, they fold outwards away from the back of the rake plate 1. In this way, the distance between adjacent rake teeth 10 can be increased to allow branches that are subject to resistance to pass through. At this time, one side of the rake teeth 10 can move close to the surface of the branch to adjust the distance of the gap adaptively. This can avoid the branches getting stuck and causing damage to the branches and leaves due to excessive pulling. Because the rake plate 10 can be pressed against the surface of the branch in real time due to the tension of the torsion spring 9, the opposite sides of the adjacent rake teeth 10 can be pushed against the stem of the fresh olive fruit on the branch.
[0028] In this embodiment, the rake teeth 10 are inclined, and a "V" shaped groove is formed between adjacent rake teeth 10. The inclination angle of the rake teeth 10 is 30°-45° to balance force and protection.
[0029] The gaps between adjacent rake teeth 10 are arranged in a "V" shape, with a maximum gap of 2.5cm and a minimum gap of 0.5cm. The minimum gap is located at the bottom of the rake plate 1, which can accommodate branches of various diameters entering between adjacent rake teeth 10. When the resistance of the branch is greater than 10N, the minimum gap can be automatically expanded to 2.5cm, so that adjacent rake teeth 10 can pass smoothly when moving based on the path of the branch.
[0030] In this embodiment, one side of the rake tooth 10 is rounded, and one side of the rake tooth 10 is covered with a silicone pad 16.
[0031] The rounded edge design of the rake teeth 10 reduces the contact pressure with the surface of fresh olives, and the silicone pad 16 provides protection from the silicone material, thus preventing scratches on the fresh olives. In this application, both the rake teeth 10 and the rake plate 1 are made of nylon plastic, which has the characteristics of being lightweight and having high structural strength.
[0032] In this embodiment: a fixed rod 17 is fixedly connected to the rake plate 1, and a guide plate 18 is fixedly connected to one end of the fixed rod 17. The guide plate 18 is located below the adjacent rake teeth 10.
[0033] The bottom of the guide plate 18 is set with an arc-shaped structure. Due to the combination and the gap between adjacent rake plates 1, in order to prevent branches from entering the gap, the guide plate 18 is set at the bottom of the corresponding adjacent rake teeth 10 on the adjacent rake plates 1. It can block the gap position. When the rake plate 1 presses down and presses the adjacent rake teeth 10 into the branches, the branches can smoothly enter between the adjacent rake teeth 10 on the individual rake plate 1.
[0034] The various embodiments in this specification are described in a related manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.
[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
