Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural implements technology, specifically a tomato vine-tilling device. Background Technology
[0002] When cultivating tomatoes in greenhouses during spring, high temperatures can easily lead to excessive vegetative growth, necessitating measures to control this excessive growth. Compared to chemical pesticides, which are more expensive, pose a risk of pesticide residues, and have inconsistent effectiveness, vegetable greenhouses tend to favor physical methods for green growth control. Using tools to bend down tomato vines effectively controls excessive growth, reduces costs, protects the environment, and promotes thicker, stronger stems, healthy growth. It also helps regulate the root crown, encouraging deeper root development, resulting in healthier root systems and improved yield and quality.
[0003] The method of laying down tomato seedlings involves watering the seedlings until they reach about 60 centimeters in height, then waiting half an hour before laying them down. During this process, workers cover a broom with a plastic bag and use the broom to beat the seedlings until they are laid down. The seedlings usually start to grow back after about a day. This method can achieve a certain effect of controlling excessive growth and can also make the seedlings stronger. However, manual beating is labor-intensive, not suitable for long-term work, and has low work efficiency. In addition, the force of beating is uncontrollable and cannot be guaranteed to be consistent each time, which can easily damage the seedlings. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a tomato vine-tilling device to solve the problems of low efficiency and easy damage to seedlings caused by manual patting of seedlings.
[0005] This utility model discloses a tomato vine-tilling device, comprising a trolley and a primary bending structure and a secondary bending structure mounted on the trolley. The primary bending structure includes a first fixed plate, with a broom movably connected to the middle of the first fixed plate in a vertical direction. The secondary bending structure includes a second fixed plate, with a telescopic rod structure fixedly connected to the center of the lower surface of the second fixed plate. An n-shaped frame is fixedly connected to the bottom of the output end of the telescopic rod structure, and a roller is rotatably connected between the two sides of the inner wall of the n-shaped frame.
[0006] As a further improvement of this utility model, the trolley includes two parallel support frames, wheels are installed at the bottom of both sides of the support frames, a connecting rod is fixedly connected to the top of one side between the two support frames, and a handrail is fixedly connected to the upper surface of the support frame and the side near the connecting rod.
[0007] As a further improvement of this utility model, the first fixing plate is fixedly connected to the upper surface between the two support frames and to the side away from the handrail. A through hole is provided in the center of the first fixing plate, and a connecting sleeve is fixedly connected to the upper surface of the first fixing plate at the position corresponding to the through hole. The broom is movably inserted between the through hole and the connecting sleeve.
[0008] As a further improvement of this utility model, both sides of the connecting sleeve are threadedly connected with a first quick-release screw, and the threaded end of the first quick-release screw passes through the interior of the connecting sleeve and is fixedly connected with a pressure plate.
[0009] As a further improvement of this utility model, the second fixing plate is fixedly connected to the upper surface between the two support frames and is located between the first fixing plate and the handrail. The telescopic rod structure includes a limiting sleeve fixedly connected to the lower surface of the connecting plate. A sliding rod is slidably connected inside the limiting sleeve. The bottom of the sliding rod is fixedly connected to the upper surface of the n-shaped frame.
[0010] As a further improvement of this utility model, an internally threaded sleeve is fixedly connected to the upper surface of the connecting plate, and a second quick-release screw is connected to the internal thread of the internally threaded sleeve. A bearing is installed on the upper surface of the slide rod, and the bottom of the second quick-release screw passes through the upper surface of the limiting sleeve and is fixedly connected to the inner ring of the bearing.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model achieves flexible movement of the device through a trolley structure. It works in conjunction with the broom in the first-stage bending structure and the roller in the second-stage bending structure to replace the traditional manual patting method, greatly reducing physical exertion. The trolley can be continuously pushed along the rows of seedlings to complete the bending of multiple seedlings at once, which is significantly more efficient than the traditional manual patting method.
[0013] 2. The broom of this utility model achieves rapid height adjustment through the connecting sleeve and the first quick-release screw, ensuring adaptability to seedlings in different growth stages. By combining the limiting sleeve and sliding rod set in the two-stage bending structure with the second quick-release screw, the downward pressure and bending depth of the roller can be precisely controlled, so that the pressure is evenly distributed along the seedling stem, avoiding local stress concentration that could lead to stem breakage or epidermal damage. The stability and repeatability of the mechanical structure ensure that the force is consistent in each bending operation, overcoming the defect of large fluctuations in force when manually beating.

[0024] Please see Figure 1-4 This utility model discloses a tomato vine bending device, including a trolley and a primary bending structure and a secondary bending structure mounted on the trolley. The primary bending structure includes a first fixed plate 4, with a broom 9 movably connected to the middle of the first fixed plate 4 in the vertical direction. The broom 9 can be a common soft broom or a similar structure with flexible branches, used for initially bending the tomato plant. The secondary bending structure includes a second fixed plate 10, with a telescopic rod structure fixedly connected to the center of the lower surface of the second fixed plate 10. An n-shaped frame 14 is fixedly connected to the bottom of the output end of the telescopic rod structure. A roller 15 is rotatably connected between the two sides of the inner wall of the n-shaped frame 14. The roller 15 is a smooth metal roller, a rubber-coated wheel, or other rotatable cylindrical structure, used for secondary or multiple bending of the plant.
[0025] This invention achieves gradual lodging of tomato plants through a two-stage bending structure. The broom 9 of the first-stage bending structure initially bends the plant stems with flexible contact, avoiding breakage caused by direct rigid crushing. The roller 15 of the second-stage bending structure crushes the plants a second time after the height of the telescopic rod is adjusted, ensuring a stable lodging angle. The trolley serves as a mobile platform, allowing the operator to continuously push the device to complete the treatment of the entire row of plants, significantly improving the efficiency of lodging and reducing the labor intensity of manual bending operations.
[0026] In this embodiment, the trolley includes two parallel support frames 1. Wheels 19 are installed at the bottom of both sides of the support frame 1. A connecting rod 2 is fixedly connected to the top of one side between the two support frames 1. A handrail 3 is fixedly connected to the upper surface of the support frame 1 and the side closer to the connecting rod 2.
[0027] Through the above technical solution, the two support frames 1 are arranged in parallel and move via wheels 19 on both sides of the bottom. The connecting rod 2 is fixed to the top of one side of the two support frames 1 by welding, bolting, or clamping, forming a lateral reinforcement structure that will not affect the plants passing through the middle of the cart. The handle 3 is fixed to the upper surface of the support frame 1 near the connecting rod 2 by welding or bolting. Its position is ergonomically designed, making it easy for the operator to stand behind the cart and push it. The parallel layout of the support frames 1 and the lateral fixation of the connecting rod 2 together enhance the structural stability of the cart and prevent the frames from deforming during movement.
[0028] In this embodiment, the first fixing plate 4 is fixedly connected to the upper surface between the two support frames 1 and to the side away from the handrail 3. A through hole 5 is provided in the center of the first fixing plate 4. A connecting sleeve 6 is fixedly connected to the upper surface of the first fixing plate 4 at the position corresponding to the through hole 5. The broom 9 is movably inserted between the through hole 5 and the connecting sleeve 6. Both sides of the connecting sleeve 6 are threaded with a first quick-release screw 7. The threaded end of the first quick-release screw 7 passes through the interior of the connecting sleeve 6 and is fixedly connected with a clamping plate 8.
[0029] Through the above technical solution, the broom handle 9 passes through the through hole 5 of the first fixing plate 4 and the connecting sleeve 6 in sequence. The swaying of the broom handle is restricted by the wrapping effect of the connecting sleeve 6. The broom handle 9 is not completely fixed to the through hole 5, forming a vertical degree of freedom of movement, so that the staff can adjust the height of the broom 9.
[0030] It should be noted that the first quick-release screw 7 is a threaded manual locking component, which can be made of stainless steel or carbon steel. Rotation is used to tighten or loosen the clamping plate 8. The clamping plate 8 is an arc-shaped or flat component that contacts the broom handle 9. It can be made of soft materials such as rubber or silicone to increase friction and protect the surface of the broom handle 9. When the first quick-release screw 7 is rotated, the clamping plate 8 moves along the screw axis, thereby clamping or releasing the broom handle 9, realizing the quick installation and removal of the broom 9, which is convenient for replacing worn parts or adjusting the type of broom 9.
[0031] In this embodiment, the second fixing plate 10 is fixedly connected to the upper surface between the two support frames 1 and is located between the first fixing plate 4 and the handrail 3. The telescopic rod structure includes a limiting sleeve 12 fixedly connected to the lower surface of the connecting plate 11. A sliding rod 13 is slidably connected inside the limiting sleeve 12. The bottom of the sliding rod 13 is fixedly connected to the upper surface of the n-shaped frame 14. An internal threaded sleeve 16 is fixedly connected to the upper surface of the connecting plate 11. A second quick-release screw 17 is threaded inside the internal threaded sleeve 16. A bearing 18 is installed on the upper surface of the sliding rod 13. The bottom of the second quick-release screw 17 passes through the upper surface of the limiting sleeve 12 and is fixedly connected to the inner ring of the bearing 18.
[0032] Through the above technical solution, the slide rod 13 is inserted into the limiting sleeve 12, and the two slide up and down through clearance fit or guide key; the bottom of the slide rod 13 is fixed to the n-shaped frame 14 by welding or bolts, so that the extension and retraction of the telescopic rod structure directly drives the height adjustment of the n-shaped frame 14 and the roller 15, so that the two-stage pressing and bending structure can adapt to the crushing needs of different plants. The second quick-release screw 17 is a manual adjustment component with external threads. Its head can be equipped with a knob or handle. The material can be carbon steel or aluminum alloy. By rotating, the slide rod 13 is driven to rise and fall. When the second quick-release screw 17 is rotated, its bottom pushes the slide rod 13 up and down along the limiting sleeve 12 through the bearing 18, thereby realizing the height adjustment of the n-shaped frame 14 and the roller 15.
[0033] For example, the head of the second quick-release screw 17 can be marked with scale lines, which makes it easy for the operator to quantitatively adjust the lifting height, realize stepless adjustment and quick locking of the height of the roller 15, reduce manufacturing costs and improve adaptability to field operations through manual mechanical adjustment structure, especially in environments with limited power supply.
[0034] In summary, when the operator pushes the handle 3 to move the cart along the field ridge, the broom 9, as the core component of the first-stage bending structure, has its flexible bristles or branches at the bottom contacting the plant stem. Utilizing its own weight and the elastic deformation of the flexible bristles, it applies downward and lateral pressure to the plant, initially bending the stem to an inclined position to avoid breakage due to hard impact. After the first-stage bending, the plant enters the second-stage bending area. The roller 15, after contacting the plant, is pushed and rotated by the plant stem as the cart moves, using rolling friction to perform a secondary pressing on the plant. The rotation of the roller 15 disperses the single-point pressure on the plant, further pressing the stem to the ground while reducing damage to the plant's surface. The first-stage bending uses flexible contact to provide initial guidance, preventing the plant from falling in a chaotic direction. The second-stage bending, through the rolling and pressing of the roller 15, consolidates the falling angle, ensuring the plant is close to the ground and neatly distributed.
[0035] like Figure 1 As shown, the spacing design of the two-stage structure allows the plant to recover briefly after being bent by the first stage before being subjected to a second stage of rolling, reducing the probability of stem rebound.
[0036] This device solves the problems of low efficiency and high plant damage rate caused by manual rice transplanting by combining the synergistic effect of a two-stage bending structure with adjustable height, flexible contact and rolling compaction mechanism.
[0037] The primary bending structure adapts to differences in plant height, while the secondary bending structure enhances the lodging effect. The trolley movement enables continuous operation, significantly improving the uniformity of lodging and operational efficiency. It is especially suitable for large-scale planting and management of tall crops such as tomatoes.
[0038] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
