[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] like Figure 1 、 Figure 2 and Figure 5 As shown, the utility model provides a technical solution: a folding mechanism of a fresh corn harvester, comprising a body 1, a plurality of groups of support rods 2 are installed at one end of the body 1, a motor 21 is installed at the bottom end of each group of support rods 2, the output end of each group of motors 21 passes through the support rods 2 and is installed with a center column 22, a fixed disk 23 is fixedly sleeved on the lower side of the surface of each group of center columns 22, and a folding assembly 3 for folding corn is equidistantly arranged on the top of each group of fixed disks 23, and each group of folding assemblies 3 includes a fixed block 31, a driven column 33 and two groups of disassembly and assembly assemblies 4, each group of fixed blocks 31 is fixedly installed on the top of the fixed disk 23, and a mounting groove 32 is provided on the top of each group of fixed blocks 31. The bottom ends of the driven columns 33 are inserted into the mounting grooves 32 and fixed by the disassembly and assembly components 4. The surfaces of each group of driven columns 33 are equidistantly connected with the gathering rods 34. The tops of each group of gathering rods 34 are provided with slots 35. This structure drives the center column 22 to rotate by starting the motor 21. The center column 22 drives the fixed disk 23 and the movable disk 61 to rotate. The fixed disk 23 will drive several groups of fixed blocks 31 to rotate together. Several groups of fixed blocks 31 drive several groups of driven columns 33 to rotate. In this way, several groups of driven columns 33 can drive several groups of gathering rods 34 to rotate together, thereby gathering the corn and moving the corn to be harvested closer to the machine body 1, which will be more convenient when harvesting.

[0029] As an implementation method in this embodiment, Figure 3 and Figure 4 As shown, each group of disassembly and assembly components 4 includes a slide groove 41 and a limit groove 44, each group of slide grooves 41 is opened on the inner wall of the installation groove 32, and a spring 42 is installed on the inner side of each group of slide grooves 41. A limit block 43 is slidably installed at the opening of each group of slide grooves 41, and the inner end of the limit block 43 is connected to the spring 42, and each group of limit grooves 44 is opened on the lower side of the surface of the driven column 33, and each group of limit blocks 43 is inserted in the limit groove 44. When the driven column 33 is inserted into the installation groove 32, and then the driven column 33 is rotated so that the limit groove 44 corresponds to the limit block 43, the limit block 43 can be rebound by the spring 42. The force is pushed into the limit groove 44 to complete the installation of the driven column 33 and the retracting rod 34. The inner end of each set of limit blocks 43 is connected to a pull rod 45, and the end of the pull rod 45 away from the limit block 43 passes through the spring 42 and extends to the outside of the fixed block 31 and is installed with a pull ring 46. The surface of each set of pull rods 45 is close to the side of the pull ring 46 and is connected to a stop block 47. This structure is more convenient to drive the pull rod 45 by pulling the pull ring 46, and then the pull rod 45 drives the limit block 43 to be pulled out of the limit groove 44, and the fixed block 31 and the retracting rod 34 can be disassembled, so that the replacement can be completed, which greatly increases the practicality of the device.

[0030] As an implementation method in this embodiment, Figure 3 and Figure 4 As shown, both sides of the outer wall of each set of fixed blocks 31 are provided with unlocking components 5 for limiting the disassembly and assembly components 4. Each set of unlocking components 5 includes a connecting rod 51 and a connecting column 53. Each set of connecting rods 51 and connecting column 53 are connected to the side of the outer wall of the fixed block 31 close to the disassembly and assembly components 4. A groove 52 is provided on the top of each set of connecting rods 51 away from the fixed block 31. A rotating rod 54 is rotatably installed on the end of each set of connecting columns 53 away from the fixed block 31, and the rotating rod 54 is stuck in the groove. The cam 46 is pulled so that the stopper 43 is pushed by the restorative force of the spring 42, and the stopper 43 drives the pull rod 45, and the pull rod 45 drives the stopper 47 until the stopper 47 is against the cam 54, so that the stopper 43 can be limited in the slide groove 41, thereby better disassembling the driven column 33 and the retracting rod 34, which greatly increases the convenience of the device.

[0031] As an implementation method in this embodiment, Figure 2 and Figure 5As shown, the top of the center column 22 is provided with a reinforcement component 6 for reinforcing the installation of the folding component 3. The reinforcement component 6 includes a movable disk 61 and a screw 64. The bottom end of the movable disk 61 is connected to the block 62. The top of the center column 22 is provided in the card slot 24. The block 62 is inserted into the card slot 24. A threaded hole 63 is provided at the top of the movable disk 61 corresponding to the block 62. The bottom end of the card slot 24 is provided in the threaded groove 25. The screw 64 passes through the threaded hole 63 and is inserted into the threaded groove 25. A handle 65 is installed at the top of the screw 64. This structure is achieved by inserting the block 62 into the card slot 24 and finally holding the handle 65 to drive the screw 64 into The movable disk 61 is installed by rotating the screw rod 64 through the threaded hole 63 and screwing it into the threaded groove 25, so that the installation of the driven column 33 and the retraction rod 34 can be reinforced, making the installation of the driven column 33 and the retraction rod 34 more stable. The bottom end of the movable disk 61 is equidistantly connected with the plug blocks 66, and the clamping blocks 62 are arranged in the centers of several groups of plug blocks 66. Each group of plug blocks 66 is inserted in the corresponding slot 35, so that the plug blocks 66 are inserted into the slots 35, which can connect the movable disk 61 to the driven column 33, so that the movable disk 61 has a better reinforcement effect on the driven column 33.

[0032] It should be noted that the block 62 and the slot 24 are both quadrilaterals, and the outer diameter of the block 62 matches the inner diameter of the slot 24 , so that the movable disk 61 can be restricted from rotating, making the movable disk 61 more firmly installed.

[0033] Working principle: If it is necessary to gather corn during harvesting, it is only necessary to start the motor 21 to drive the central column 22 to rotate, and the central column 22 drives the fixed disk 23 and the movable disk 61 to rotate, and the fixed disk 23 drives several groups of fixed blocks 31 to rotate together, and several groups of fixed blocks 31 drive several groups of driven columns 33 to rotate, so that several groups of driven columns 33 can drive several groups of gathering rods 34 to rotate together, so as to gather the corn and move the corn to be harvested closer to the machine body 1, which will make harvesting more convenient.

[0034] When the folding rod 34 is damaged due to long-term use, it is only necessary to first hold the handle 65 and turn it, and the handle 65 drives the screw 64 to rotate, and the screw 64 is pulled out from the threaded hole 63 and the threaded groove 25 through the thread rotation. At this time, the movable disk 61 can be pulled upward, so that the movable disk 61 drives the block 62 to be pulled out from the groove 24. At this time, the movable disk 61 will also drive the plug block 66 to be pulled out from the slot 35, thereby completing the disassembly of the movable disk 61, so that the reinforcement of the installation of several groups of folding rods 34 can be released, thereby facilitating the disassembly of several groups of folding rods 34, and then pulling the pull ring 46 drives the pull rod 45, and the pull rod 45 drives The limit block 43 is pulled out of the limit groove 44 and moved into the slide groove 41 to compress the spring 42, so that the fixed block 31 and the retracting rod 34 can be disassembled, which greatly increases the practicality of the device. At this time, the rotating rod 54 is rotated to clamp the rotating rod 54 in the groove 52, and the pull ring 46 can be loosened, so that the limit block 43 is pushed by the restorative force of the spring 42, and the limit block 43 drives the pull rod 45, and the pull rod 45 drives the stopper 47 until the stopper 47 is abutted against the rotating rod 54. In this way, the limit block 43 can be limited in the slide groove 41, thereby better removing the driven column 33 and the retracting rod 34, which greatly increases the convenience of the device.

[0035] In addition, if a new driven column 33 and retracting rod 34 need to be installed, it is only necessary to rotate the rotating rod 54 first, remove the rotating rod 54 from the groove 52, unlock the limit block 43, and then the driven column 33 can be inserted into the installation groove 32. Then, the driven column 33 is rotated so that the limit groove 44 corresponds to the limit block 43. The limit block 43 can be pushed into the limit groove 44 by the restoring force of the spring 42, completing the installation of the driven column 33 and the retracting rod 34. Finally, the movable plate 61 is placed on the top of the center column 22. The end is opened, so that the block 62 and the insert block 66 are respectively inserted into the card slot 24 and the slot 35. Finally, the handle 65 is held by hand to drive the screw 64 to be inserted into the threaded hole 63 and rotated. The screw is rotated until the screw 64 passes through the threaded hole 63 and is screwed into the threaded groove 25. The installation of the movable disk 61 is completed, thereby completing the replacement. In this way, the installation of the driven column 33 and the retracting rod 34 can be reinforced, making the installation of the driven column 33 and the retracting rod 34 more stable. This makes it more stable when retracting, greatly increasing the stability of the device.

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
