[0003] However, incompatible with industrialized planting, after the vines are harvested, the traditional sweet potato stems are generally still in the stage of manually separating the stems and leaves from the vines. Manual operation is slow, especially in the context of large-scale planting, which requires a large number of laborers to complete the harvesting task. This undoubtedly increases production costs and may lead to labor shortages, affecting the separation progress. Summary of the Invention

[0004] The purpose of this invention is to provide a device for separating the stems and leaves of sweet potatoes that is used for leafy vegetables, in order to solve the problems of slow operation, high cost, and reduced separation progress caused by manual operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes a separation platform, on which a vine-winding mechanism is rotatably mounted. The vine-winding mechanism includes multiple annularly distributed winding rods, which form a winding axis when rotated, and a vine slit is formed between two adjacent winding rods. A vine-removing mechanism is fixed on the platform, which includes multiple annularly distributed pushing rods placed within the vine slit. The pushing rods move along the length of the winding rods. A vine stem separation mechanism is also fixed on the platform, which includes a separation opening with an adjustable size.

[0006] As a further description of the above technical solution: multiple winding rods are fixed around a large disc, a shaft tube is coaxially fixed to the large disc, the shaft tube is rotatably connected to the bearing seat of the separation table through a bearing, and a servo motor for driving the shaft tube to rotate is fixed on the table surface.

[0014] 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.

[0015] like Figure 1 - Figure 5 As shown, this utility model provides a device for separating the stems and leaves of leafy sweet potatoes and their vines. It includes a separation platform 10, on which a vine-winding mechanism 20 is rotatably mounted. The platform 11 is made of corrosion-resistant and easy-to-clean stainless steel. The vine-winding mechanism 20 includes multiple annularly distributed winding rods 22, which are evenly distributed in a ring to form a central winding axis. A vine slit is formed between two adjacent winding rods 22. A vine-removing mechanism 30 is fixed on the platform 11. A vine-stem separation mechanism 40 is also fixed on the platform 11. The vine-stem separation mechanism 40 includes a separation port 43 with an adjustable opening size. The vine-removing mechanism 30 includes multiple annularly distributed... A pusher rod 32 is placed inside the vine slit. The pusher rod 32 moves along the length of the winding rod 22, passing one end of the vine through the separation port 43. The diameter of the separation port 43 is adjusted to accommodate different vines. Then, the end of the vine is placed into the vine slit. When the winding rod 22 rotates, the sweet potato vine will be wrapped around the winding axis formed by these rods. The toughness and flexibility of the vine allow it to wrap neatly. During the wrapping process, the separation port 43 can separate and cut off the stems on the vine. After the stems and leaves are separated from the vine, the vine wraps around the winding axis. Finally, the pusher rod 32 can push the wrapped vine off, thereby reducing labor costs and improving separation efficiency.

[0016] like Figure 3 , Figure 5 As shown, multiple winding rods 22 are arranged in a ring and fixed on a large disc 21, with the winding rods 22 parallel to the axis of the large disc 21. A shaft tube 23 is coaxially fixed on the large disc 21, and the shaft tube 23 is rotatably connected to the bearing seat 14 of the separation table 10 through a bearing. A servo motor 24 is fixed on the table surface 11. Both the output shaft of the servo motor 24 and the shaft tube 23 are fixed with sprockets 26. The two sprockets 26 are driven by a chain 25. When the servo motor 24 is powered on, the large disc 21 and its fixed winding rods 22 are rotated in cooperation with the chain 25.

[0017] like Figure 3 , Figure 5As shown, multiple pushing rods 32 are arranged in a ring and fixed on a small disc 31. The small disc 31 is coaxial with the large disc 21, and the pushing rods 32 are perpendicular to the axis of the small disc 31. The small disc 31 is rotatably connected to a servo electric cylinder 33. The cylinder body of the servo electric cylinder 33 is fixed on the separation platform 10. The piston rod of the servo electric cylinder 33 passes through the shaft tube 23, the large disc 21, and the sprocket 26, and is rotatably connected to the small disc 31 through a bearing. When the large disc 21 rotates, the small disc 31 and the pushing rods 32 rotate under the drive of the winding rod 22. The piston rod of the servo electric cylinder 33 extends outward to drive the small disc 31 and the pushing rods 32 to push the vines wrapped on the winding shaft off the winding rod 22.

[0018] like Figure 2 As shown, two arc-shaped fixed rods 41 with upward openings are fixed on the platform 11. A shaft seat 45 is fixed on the platform 11. The shaft seat 45 is rotatably connected to an arc-shaped movable rod 42 with downward openings via a shaft. The movable rod 42 is placed between the two fixed rods 41. When the vine is placed into the opening between the fixed rod 41 and the movable rod 42, the movable rod 42 is flipped downwards around the shaft, so that the vine is clamped between the fixed rod 41 and the movable rod 42. Through the separation port 43 formed by the movable rod 42 and the fixed rod 41, and under the action of the gravity of the movable rod 42 itself, the separation port 43 can be adaptively adjusted according to the diameter of the vine.

[0019] like Figure 2 As shown, a spring sheet 44 is fixed on the shaft seat 45, and the top of the spring sheet 44 presses on the movable rod 42. Under normal conditions, the spring sheet 44 is in an elastic bending state, so that the movable rod 42 maintains the pressure on the vine through the elastic rebound of the spring sheet 44.

[0020] like Figure 3 As shown, by providing a discharge port 12 on the table 11 below the vine stem separation mechanism 40, when the vine is entangled, the separated stems and leaves pass through the discharge port 12 and are guided to the bottom collection frame by a downwardly inclined guide plate 13 fixed on one side edge of the discharge port 12.

[0021] Working principle: One end of the vine (in this application, the end where most of the stem and vine form an acute angle) is passed through the separation port 43, and then the other end of the vine is placed into the vine seam. The servo motor 24 is started to drive the large disc 21 and the winding rod 22 to rotate. When the vines press against each other, the vines can be released. When the vines are wrapped, when the vines with stems and leaves pass through the fixed rod 41 and the movable rod 42, the stems and leaves are separated from the vines by the blocking of the fixed rod 41 and the movable rod 42. Furthermore, since the stem has leaves, and the leaves are larger than the diameter of the separation opening 43, when the stem and vine are stuck together, the stuck part of the stem and vine can be broken by the obstruction of the leaves when the leaves reach the separation opening 43. Once the vines have finished wrapping and the stems have been separated from the vines, the piston rod of the servo electric cylinder 33 extends to push the vines off the wrapping rod 22. Finally, the piston rod is reset, and the above actions are repeated to perform the separation of the next vine from the stem.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
