Description

Technical Field

[0001] This utility model belongs to the field of fruit thinning technology, specifically relating to a fruit thinning device for Wogan oranges. Background Technology

[0002] Wogan (Woju) is a spring mandarin orange, a late-maturing hybrid citrus variety characterized by vigorous growth, minimal fruit drop during winter, high fruit set capacity, and a long harvest period. The fruit is plump and has a festive appearance, tender and smooth flesh, thin skin, and juicy orange flesh. It boasts a sweet, mellow, low-acid, and refreshing taste, and is highly nutritious, containing abundant vitamins, making it a favorite among consumers.

[0003] In the cultivation of Wogan tangerines, when the number of flowers, fruits, and the tree's load are excessive, thinning flowers and fruits can control the number of fruits, preventing fruit drop and nutrient waste caused by excessive fruit set. This improves the growth conditions of the remaining fruits, resulting in more uniform fruit size and higher quality. However, current thinning methods for Wogan tangerines mainly rely on manual shearing. When thinning fruits at higher points on the tangerine trees, workers need to climb to do so. Thinning large numbers of tangerine trees requires frequent climbing, which is not only labor-intensive and reduces efficiency but also poses a risk of falls and injuries. Therefore, this application proposes a Wogan tangerine thinning device. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fruit thinning device for Wogan oranges, which aims to solve the technical problems of low fruit thinning efficiency and the risk of falling from height under the existing technology.

[0025] 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.

[0026] This embodiment provides a fruit thinning device for Wogan oranges, the structural schematic diagram of which is shown below. Figures 1-6As shown, the system includes a frame 1. An arc-shaped plate 6 and a ring-cutting blade 7 are located at one end of the frame 1. The arc-shaped plate 6 is fixedly connected to the frame 1, and the ring-cutting blade 7 is nested within the arc-shaped plate 6. An arm 8 is located inside the frame 1, and a pull rope 4 is connected to the arm 8. Pulling the arm 8 with the pull rope 4 moves the ring-cutting blade 7 towards the arc-shaped plate 6. A support plate 5 is fixed to the bottom of the frame 1, and a control lever 2 is located at the bottom of the support plate 5. With this structure, workers can hold the control lever 2 to lift the frame 1 to the Wogan mandarin orange tree, allowing the Wogan mandarin orange to be removed to pass between the ring-cutting blade 7 and the arc-shaped plate 6. Pulling the pull rope 4 moves the ring-cutting blade 7 towards the arc-shaped plate 6, where it passes through and overlaps with the arc-shaped plate 6, thus cutting and removing the Wogan mandarin orange, achieving the purpose of fruit thinning. Compared to the traditional method of manually thinning fruit with shears, workers can perform fruit thinning on the ground by holding the control lever 2, eliminating the need for repeated climbing and avoiding the risk of falls, thereby improving fruit thinning efficiency.

[0027] In this embodiment, the arc plate 6 is provided with a groove 9, and the two ends of the ring cutter 7 are embedded in the groove 9. The ring cutter 7 can pass horizontally through the groove 9, ensuring that the ring cutter 7 can cross and overlap with the arc plate 6 under the traction of the pull rope 4, thereby removing the Wogan fruit.

[0028] In a further embodiment, the two side arms of the frame 1 are hollow inside, and guide grooves 10 are provided on the inner sidewall of the frame 1. The two ends of the bar arm 8 pass through the guide grooves 10 and extend into the side arms of the frame 1 and are connected to push plates 11. The two ends of the ring cutter 7 also pass through the guide grooves 10 and extend into the side arms of the frame 1. A connecting rod 13 is connected between the push plate 11 and the end of the ring cutter 7. A spring 12 is provided on the side of the push plate 11 away from the connecting rod 13. A pull ring 14 is provided on the bar arm 8, and one end of the pull rope 4 is tied to the pull ring 14. The other end of 4 is tied with a pull rod 20. When the worker holds the pull rod 20 and pulls the pull rope 4, the pull rope 4 drives the bar arm 8 away from the arc plate 6. The bar arm 8 drives the ring cutter 7 to move towards the arc plate 6 until they overlap through the push plate 11 and the connecting rod 13, so as to achieve the purpose of thinning fruit. During this process, the push plates 11 at both ends of the bar arm 8 push the spring 12 to compress. After the pull rope 4 is released, the spring 12 can elastically push the push plate 11 to push the connecting rod 13 to force the ring cutter 7 to return to its original position, so that the thinning operation can be repeated.

[0029] In a further embodiment, a handle 3 is provided at the bottom of the control lever 2 for easy gripping by the operator. A guide ring 19 is provided on the side wall of the control lever 2 near the handle 3. The pull rope 4 passes through the guide ring 19 and is used to limit and guide the bottom end of the pull rope 4. A through groove 16 is provided on the end wall of the frame 1 away from the arc plate 6. A pair of first guide wheels 17 are rotatably installed in the through groove 16. The pair of first guide wheels 17 are distributed vertically, and the pull rope 4 passes between the pair of first guide wheels 17. A guide frame 15 is provided on the end wall of the frame 1 at a position corresponding to the through groove 16. A pair of second guide wheels 18 are rotatably installed side by side in the guide frame 15. The pull rope 4 passes between the pair of second guide wheels 18. The arrangement of the pair of first guide wheels 17 and the pair of second guide wheels 18 can guide the pull rope 4, reduce the wear between the pull rope 4 and the frame 1, and improve durability.

[0030] In a further embodiment, the control lever 2 is composed of multiple standard levers 21 spliced ​​end to end. Each end of a standard lever 21 is provided with a screw hole 22 and a stud 23, which are threaded together. This structure allows the control lever 2 to be disassembled into multiple standard levers 21 for easy storage and carrying. Furthermore, by increasing or decreasing the number of standard levers 21, the lifting height of the frame 1 can be adjusted to accommodate fruit trees of different heights. Rubber pads are provided at the bottom of each standard lever 21 to facilitate the tightening and splicing of adjacent standard levers 21.

[0031] Working principle: In use, multiple standard poles 21 are joined end to end to form a control lever 2. The operator holds the control lever 2 and lifts the frame 1 to the Wogan mandarin orange tree. By manipulating the control lever 2, the Wogan mandarin orange to be removed passes between the ring cutter 7 and the arc plate 6. Then, the operator holds the pull rod 20 and pulls the pull rope 4. The pull rope 4, through the bar arm 8 and the connecting rod 13, moves the ring cutter 7 toward the arc plate 6 until the ring cutter 7 passes through the cutting groove 9 and intersects with the arc plate 6, thus cutting and removing the Wogan mandarin orange, achieving the purpose of fruit thinning. As the pull rope 4 forces the ring cutter 7 to move closer to the arc plate 6, the push plates 11 at both ends of the bar arm 8 push the spring 12 to compress. After the pull rope 4 is released, the spring 12 can elastically push the push plate 11 to push the connecting rod 13 to force the ring cutter 7 to return to its original position. This allows for repeated fruit thinning operations. Compared with the traditional method of manually holding scissors for fruit thinning, workers can perform fruit thinning operations on the ground by holding the control lever 2, eliminating the need for repeated climbing and avoiding the risk of workers falling from heights, thus improving fruit thinning efficiency.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
