Description

Technical Field

[0001] This utility model relates to the field of lifting structure technology, specifically a lifting structure for a houttuynia cordata harvester. Background Technology

[0002] Houttuynia cordata is loved by many people for its many beneficial effects on the human body, such as antibacterial, diuretic, anti-inflammatory, anti-tumor, and immune-enhancing properties. When harvesting Houttuynia cordata planted in the soil, a Houttuynia cordata harvester is required.

[0003] A search revealed a patent, CN207720706U, which discloses a harvesting device for Houttuynia cordata. This device includes a frame with wheels and a drive assembly at the bottom for driving the wheels; a seating area for personnel at the top of the frame; and a root-lifting device connected to the frame. The root-lifting device includes a root-lifting shovel and soil dividers on both sides of the shovel. The device provided in this application has a simple and reasonable structure, low manufacturing cost, and is easy to install and use. It can automate the harvesting of Houttuynia cordata roots, greatly reducing labor intensity. The device can move independently without needing to cooperate with other equipment to complete the entire harvesting process. It can perform two compaction processes on the soil clods, ensuring thorough harvesting and significantly reducing waste. Simultaneously, the soil dividers at the front end make root-lifting operations easier and smoother.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative document describes the harvesting of houttuynia cordata from the ground using a root-removing shovel. However, in actual operation, due to the unevenness of the ground, the height of the root-removing shovel needs to be adjusted according to different ground conditions to ensure the best harvesting effect. The root-removing shovel in the aforementioned comparative document has poor position adjustability, resulting in poor applicability of the overall harvester. Therefore, there is an urgent need in the field to improve the houttuynia cordata harvester to overcome the shortcomings of the existing technology. Utility Model Content

[0024] 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.

[0025] Please see Figures 1-4A lifting structure for a houttuynia cordata harvester includes a harvester body, which includes a movable frame 1. A harvesting roller 2 for harvesting is located at the front end of the frame 1. Lifting frames 3 are rotatably connected to opposite sides of the frame 1. The harvesting roller 2 is rotatably connected between the ends of the two lifting frames 3. A mounting plate 4 is fixedly installed on the upper part of the frame 1. Two symmetrical fixed seats 5 are fixedly installed on the mounting plate 4. A rotating shaft 8 passes through and is rotatably connected between the two fixed seats 5. A rotating rod 6, with one end slidably connected to the lifting frame 3, is fixedly connected to both sides of the rotating shaft 8. A drive motor 7 for driving the rotating shaft 8 is provided on the mounting plate 4. A gear 9 is fixedly installed on the side of the rotating shaft 8. A mounting bracket 11 adapted to the gear 9 is fixedly installed on the upper part of the mounting plate 4. The mounting bracket 11 contains... The top wall is provided with a rack 10 that meshes with the gear 9. The drive motor 7 drives the rack 10 to move. A sliding block 12 is fixedly installed on the upper side of the rack 10. The inner top wall of the mounting frame 11 is provided with a sliding groove 13 that matches the sliding block 12. An adjusting screw 23 is rotatably connected in the sliding groove 13, with one end fixedly installed to the output end of the drive motor 7. The adjusting screw 23 passes through the sliding block 12 and is threadedly connected to it. A rotating shaft 14 is rotatably connected to the end of the rotating rod 6 near the lifting frame 3. A through opening 15 that matches the rotating shaft 14 is provided on the side of the lifting frame 3 near the rotating rod 6. A conveyor belt 20 for conveying is provided on the frame 1. A guide plate 21 is provided between the conveyor belt 20 and the harvesting roller 2. A stabilizing seat 22 for stabilizing the rotating shaft 8 is fixedly installed on the mounting plate 4.

[0026] Specifically, when it is necessary to harvest houttuynia cordata, the frame 1, which can operate in the field, is used to move the houttuynia cordata to the harvesting position. The drive motor 7 is activated, and its output drives the adjusting screw 23 to rotate. When the adjusting screw 23 rotates, it drives the sliding block 12 to move within the sliding groove 13. The sliding block 12 drives the rack 10 to move, and the rack 10 drives the gear 9 to rotate. The gear 9 drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the rotating rod 6 to rotate. The rotating shaft 14 at one end of the rotating rod 6 slides within the through-hole 15, and through the rotating shaft 14, it drives the lifting frame 3 to move upwards at the end closest to the rotating rod 6. Since the lifting frame 3 is rotatably connected to the side of the frame 1, when the lifting frame 3 closest to the rotating rod 6 moves upwards, the end of the lifting frame 3 away from the rotating rod 6 moves downwards. This end of the lifting frame 3 away from the rotating rod 6 drives the harvesting roller 2 to move downwards. The side of the harvesting roller 2 is fixed... The device has several insertion rods that rotate and insert into the ground to bring out the houttuynia cordata. The rods are then guided by the guide plate 21 and pushed onto the conveyor belt 20. The conveyor belt 20 transports the houttuynia cordata to the next position. The angle of the lifting frame 3 can be adjusted by the drive motor 7 according to different terrains, thereby adjusting the height of the harvesting roller 2. This improves the applicability and suitability of the overall device. In addition, the stabilizing seat 22 stabilizes the rotating shaft 8 to prevent it from deforming due to its long length.

[0027] As a technical optimization of this utility model, two symmetrical pressing plates 16 are provided in the through-hole 15. The two pressing plates 16 are located on opposite sides of the rotating shaft 14. The opposite side walls of the through-hole 15 are provided with movable slots 17 that are adapted to the pressing plates 16. Several elastic elements 18 are provided between the pressing plates 16 and the inner side walls of the movable slots 17. A guide post 19 that passes through the lifting frame 3 is fixedly connected to one side of the pressing plate 16. The elastic elements 18 are sleeved on the side of the guide post 19.

[0028] Specifically, when the rotating rod 6 rotates, the rotating shaft 14 pushes the pressing plate 16 to move. At the same time, it cooperates with the elastic element 18, which is specifically a spring. The function of the elastic element 18 is to prevent the rotating shaft 14 from being subjected to hard contact due to sudden rotation of the rotating rod 6, which would cause the rotating shaft 14 to wear out and be easily damaged. In addition, when the drive motor 7 is not started during the harvesting process, the lifting frame 3 can slightly change its position to prevent damage to the lifting frame 3 or the rotating shaft 14 due to rigid contact. The function of the guide column 19 is to prevent the elastic element 18 from undergoing radial deformation, and the guide column 19 can limit and fix the position of the pressing plate 16 to prevent the pressing plate 16 from deviating.
