[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0027] like Figures 2 to 5 As shown, a harvester reel spring includes a working spring 1, a connecting ring 2 fixedly mounted on the top of the working spring 1, and a connecting notch 21 on the connecting ring 2. In this embodiment, a locking structure is located on the side of the connecting ring 2 near the connecting notch 21 to adjust the size of the connecting notch 21. A positioning member 3 is located on the side of the working spring 1 near the connecting ring 2. A splicing pin 4 is located on one side of the positioning member 3, a rotating member 6 is rotatably located on the other side of the positioning member 3, and a splicing groove 5 is located between the rotating member 6 and the positioning member 3 to ensure that the springs move synchronously when installed on the reel. The splicing pin 4 and the splicing groove 5 are at the same horizontal height. A connecting mechanism is located between the rotating member 6 and the positioning member 3 to fix the rotating member 6 to the positioning member 3. A limiting structure is located between the rotating member 6 and the positioning member 3 to ensure that the rotating member 6 is pressed tightly against the positioning member 3. The design of the splicing groove 5 and the splicing pin 4 in this embodiment is to ensure that each reel spring maintains a consistent arc during the rotation of the reel to harvest the crops.
[0028] The limiting structure in this embodiment includes a first limiting groove 311 and a second limiting groove 312, which are disposed on the positioning member 3. The first limiting groove 311 and the second limiting groove 312 are parallel. A third limiting groove 61 and a fourth limiting groove 62 are disposed on the rotating member 6, and the third limiting groove 61 and the fourth limiting groove 62 are parallel. The central axes of the first limiting groove 311, the second limiting groove 312, the third limiting groove 61, and the fourth limiting groove 62 are all perpendicular to the rotation direction of the rotating member 6. A first limiting tension spring 71 is disposed between the first limiting groove 311 and the third limiting groove 61, and its two ends are fixedly connected to the first limiting groove 311 and the third limiting groove 61, respectively. A second limiting tension spring 72 is disposed between the second limiting groove 312 and the fourth limiting groove 62, and its two ends are fixedly connected to the second limiting groove 312 and the fourth limiting groove 62, respectively. This design allows the first and second limiting springs to be concealed within the limiting grooves after the springs are installed on the reel, resulting in a cleaner and more aesthetically pleasing appearance. The design of the first limiting spring 71 and the second limiting spring 72 in this embodiment ensures that, in a relaxed, unforced state, both ends of the rotating member 6 remain tightly pressed against the positioning member 3 under the action of the first and second limiting springs 71 and 72. This makes it easier for the first locking bolt 8 to align with its first threaded hole 32, facilitating a smoother connection between the two.
[0029] In this embodiment, the rotating groove 31 is located at the end of the positioning member 3 away from the working spring member 1. The rotating groove 31 has a cuboid structure, and both ends of the rotating member 6 are provided with rotating members 33 that are rotatably connected to the sidewalls of the rotating groove 31. The rotating members 33 have a cylindrical structure. The design of the rotating groove 31 allows the rotating member 6 to be concealed within the rotating groove 31, making the appearance of this utility model simpler and more aesthetically pleasing.
[0030] The connecting mechanism in this embodiment includes a first connecting structure and a second connecting structure. The first connecting structure includes a fifth limiting groove 63, a first limiting groove 311 and a second limiting groove 312 disposed on the side of the rotating member 6 near the end of the positioning member 3, a first sliding hole 631 disposed at the bottom of the fifth limiting groove 63, a first locking bolt 8 slidably disposed in the first sliding hole 631, and a first threaded hole 32 disposed on the positioning member 3 and threadedly connected to the first locking bolt 8. This design ensures that when the reel spring is working normally, the rotating member 6 is not easily affected and disengaged from the positioning member 3 because it is locked by the first locking bolt 8. Moreover, when the reel spring is damaged and disassembly is required, the splicing pin 4 in the splicing groove 5 can be removed by rotating the rotating member 6, ensuring that the problematic spring can be disassembled without moving the other springs.
[0031] In this embodiment, the limiting bolt 81 is disposed within the fifth limiting groove 63, and the limiting bolt 81 is fixedly connected to the first locking bolt 8. The first connection structure is identical to the second connection structure. This design is intended to prevent the first locking spring from disengaging from the rotating part 6 when it disengages from the first threaded hole 32, due to the action of the fifth limiting groove 63 and the limiting bolt 81, thus preventing the first locking bolt 8 from being lost.
[0032] The locking structure in this embodiment includes a first locking plate 22 and a second locking plate 23 near the two ends of the insertion notch 21 of the insertion ring 2. The first locking plate 22 and the second locking plate 23 are parallel to each other and are both fixedly connected to the insertion ring 2. A second sliding hole 221 is provided on the first locking plate 22, and a second locking bolt 9 is slidably provided in the second sliding hole 221. A second threaded hole 231 is provided on the second locking plate 23, and the second locking bolt 9 is threadedly connected to the second threaded hole 231. This design makes the insertion ring 2 easy to install and remove, and also allows the insertion ring 2 to be more securely installed on the reel, preventing the insertion ring 2 from detaching due to the rotation of the reel. In this embodiment, the insertion ring 2 can also be made of an elastic material, so that when the insertion ring 2 is sleeved on the reel, it can more firmly hold the reel and prevent it from detaching from the reel.
[0033] In this embodiment, the positioning element 3 has a cuboid structure, and the mounting hole 11 is set on the working spring 1. The mounting hole 11 has a rectangular structure, and the positioning element 3 passes through the mounting hole 11 and is fixed to the mounting hole 11. The shortest distance between the two ends of the positioning element 3 and the mounting hole 11 is equal. This symmetrical design not only increases the aesthetic appeal of symmetry, but also ensures that the spacing between the adjacent reel fingers on both sides remains consistent, facilitating the harvesting of crops by the reel fingers.
[0034] The disassembly process of this embodiment is as follows: Rotate the first locking bolt 8 on the reel spring to be disassembled, and the first locking bolt 8 on the adjacent reel spring, so that the first locking bolt 8 disengages from the first threaded hole 32. Then rotate the rotating part 6 on the reel spring to be disassembled, and the rotating part 6 on the adjacent reel spring. Finally, rotate the second locking bolt 9 and remove the reel spring to be disassembled. The installation process of the new reel spring is as follows: Insert the insertion ring 2 on the spring to be installed into the reel. Rotate the rotating part 6 on the reel spring and the rotating part 6 on the adjacent reel spring. Then insert the splicing pin 4 on the reel into the adjacent open splicing groove 5 and engage the adjacent splicing pin 4 into the open splicing groove 5 of the spring. Finally, rotate the first locking bolt 8 and the second locking bolt 9 to complete the installation of the new reel spring.
[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
