[0001] This utility model relates to the field of whole seedling transplanting technology, and in particular to a whole root transplanter for plant seedlings. Background Technology

[0002] Existing soil-clamping transplanting tools work by adding a structure above the curved shovel head to press down the internal soil. After lifting the shovel handle, the operator uses the other hand to operate a connecting rod to press down the soil, thus achieving the function of digging holes or transplanting seedlings. The soil-pressing function requires the operator to lift the shovel handle with one hand, control the pressing rod with the other hand, and lift the entire tool with soil or seedling with the other hand. This is laborious, difficult to operate, and inefficient. Utility Model Content

[0003] To address the above shortcomings, this utility model provides a whole-root transplanter for plant seedlings to solve the technical problems mentioned in the background.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A whole-root transplanter for plant seedlings includes a seedling picking tube and a pressure rod component, wherein the seedling picking tube is fixedly connected to the lower part of the pressure rod component;

[0006] The pressure bar component includes a grip, a first vertical bar, a first mounting plate, and a second vertical bar. The grip is fixed to the upper part of the first vertical bar, the first mounting plate is fixed to the lower part of the first vertical bar, and there are two second vertical bars that are fixed to the two ends of the first mounting plate. The seedling tube is fixed to the other end of the two second vertical bars.

[0007] The launching component includes a pull rod, a first toothed rod, a first gear, a second toothed rod, a second gear, a second mounting plate, a third vertical rod, and a push ring. The first vertical rod includes a mounting groove. The first gear and the second gear are coaxial and rotatably mounted in the mounting groove. The second toothed rod is fitted onto the second gear and extends out of the first vertical rod at its lower part. The second mounting plate is fixed to the lower part of the second toothed rod. There are two third vertical rods, which are correspondingly fixed to both ends of the second mounting part. The push ring is fixed to the other end of the two third vertical rods and is located inside the seedling tube. The first toothed rod is fitted onto the first gear and is arranged opposite to the second toothed rod. The first vertical rod has a longitudinally arranged sliding groove on the upper part of one side of the first toothed rod. The pull rod is fixed to the first toothed rod and passes through the sliding groove and is arranged parallel to the handle.

[0008] Preferably, the diameter of the first gear is smaller than the diameter of the second gear.

[0009] Preferably, the pressure bar component also includes two rubber grips, which are respectively sleeved on both ends of the grip bar.

[0010] Preferably, the seedling collection tube also includes a foot pedal, which is fixed to the side of the upper part of the seedling collection tube.

[0011] Preferably, the seedling tube includes serrations, and the serrations are multiple and evenly distributed circumferentially in the lower part of the seedling tube.

[0012] Preferably, the ejector component further includes a spring, which is located between the first rack and the grip, with both ends of the spring fixedly connected to the grip and the first rack respectively.

[0013] Preferably, the thickness of the serrations gradually increases from bottom to top, and the lower part of the seedling tube has the same thickness as the upper part of the serrations.

[0014] Preferably, the pressure rod component also includes a protective cover, which is placed on the first vertical rod and covers the push-out component. The protective cover is fixedly connected to the first vertical rod by bolts.

[0015] Compared with existing technologies, the advantages of this invention are as follows: This device includes a seedling-taking tube, a pressing rod component, and a pushing component, with the seedling-taking tube fixedly connected to the lower part of the pressing rod component. The connection between the gripping rod and the first vertical rod forms a stable support structure, allowing the user to smoothly press the whole seedling into the seedling-taking tube by gripping the gripping rod and applying force. The innovative design of the pushing component achieves the function of pushing out the whole seedling during transplanting through a combination of gears and racks. The connection design between the pull rod and the first rack allows the user to pull the pull rod to drive the entire gear system to rotate when taking out the whole seedling. The cooperation between the first rack and the first gear, and between the second rack and the second gear, causes the first rack to move upward when the user pulls the pull rod, while the second rack moves downward accordingly. The push ring then pushes the whole seedling out of the seedling-taking tube through this relative motion. The user can complete the seedling-taking and pushing operations by gripping the gripping rod and the pull rod with both hands, without the need for multiple adjustments or repositioning of the tools. This integrated design optimizes the operation process and improves work efficiency, especially in large-scale seedling transplanting operations, significantly saving time and reducing labor consumption.

[0025] This utility model provides a plant seedling whole-root transplanter, aiming to improve existing seedling picking devices, making seedling picking or transplanting more labor-saving and convenient. Figures 1-4As shown, the device includes a seedling-taking tube 2, a pressure rod component 1, and a push-out component 3. The seedling-taking tube 2 is fixedly connected to the lower part of the pressure rod component 1. The pressure rod component 1 includes a gripping rod 101, a first vertical rod 102, a first mounting plate 104, and a second vertical rod 105. The gripping rod 101 is fixedly connected to the upper part of the first vertical rod 102, the first mounting plate 104 is fixedly connected to the lower part of the first vertical rod 102, and there are two second vertical rods 105, which are correspondingly fixed to both ends of the first mounting plate 104. The seedling-taking tube 2 is fixedly connected to the other end of the two second vertical rods 105. The pressure rod component 1 is used for the user to hold and to provide downward pressure when taking seedlings. The ejector component 3 includes a pull rod 308, a first rack 301, a first gear 302, a second rack 304, a second gear 303, a second mounting plate 305, a third vertical rod 306, and a push ring 307. The first vertical rod 102 includes a mounting groove 103. The first gear 302 and the second gear 303 are coaxial and rotatably mounted in the mounting groove 103. The second rack 304 is fitted onto the second gear 303. A through hole is provided at the lower part of the first vertical rod 102, and the second rack 304 extends from the lower part of the first vertical rod 102. Extending out, the second mounting plate 305 is fixed to the lower part of the second toothed rod 304. There are two third vertical rods 306, which are fixed to the two ends of the second mounting part. The push ring 307 is fixed to the other end of the two third vertical rods 306 and is located inside the seedling tube 2. The first toothed rod 301 is fitted on the first gear 302 and is arranged opposite to the second toothed rod 304. The first vertical rod 102 is longitudinally provided with a sliding groove on the upper part of one side of the first toothed rod 301. The pull rod 308 is fixed to the first toothed rod 301 and passes through the sliding groove and is arranged parallel to the handle 101.

[0026] When using this device, the user aligns the seedling collection tube 2 with the desired seedling, grips the handle 101 with both hands, and presses down to push the seedling into the collection tube 2. Then, the user lifts the device to remove the seedling from the collection tube 2, completing the seedling removal action. Next, the user operates the pull rod 308, gripping it with one hand to raise it. This causes the first gear 301 to move upwards, rotating the first gear 302 and the second gear 303, which in turn causes the second gear 304 to move downwards. Finally, the push ring 307 pushes the seedling out of the collection tube 2. This tool is designed with ease and comfort in mind. The user can complete the seedling removal and ejection operations simply by gripping the handle 101 and the pull rod 308 with both hands, eliminating the need for multiple adjustments or repositioning of the tool. This integrated design optimizes the operation process and improves work efficiency, especially in large-scale seedling transplanting operations, significantly saving time and reducing labor costs. With the mechanized gear system, users can quickly complete all the steps of transplanting seedlings, avoiding the tedious actions of frequent bending and exertion in the traditional manual transplanting process, and greatly improving work efficiency.

[0027] In a preferred embodiment, to further improve operational efficiency and conform to ergonomic design, the diameter of the first gear 302 is one-third that of the second gear 303. This gear ratio design means that when the first gear 302 rotates one revolution, the second gear 303 rotates three revolutions. Through this transmission ratio, when the user pulls the lever 308, they only need to pull the seedling tube 2 to one-third of its height to push the push ring 307 out the same distance as the seedling tube 2. This design significantly reduces the force and range of motion required by the user, thereby reducing hand fatigue and making the operation process smoother and more efficient. More importantly, the position of the lever 308 is optimized to be closer to the grip 101, conforming to ergonomic principles, reducing the range of hand extension, and improving operational comfort. This design makes it less tiring for users during long-term use, especially suitable for continuous large-scale transplanting operations, greatly improving the user experience and work efficiency of the tool. In addition, the optimized position of the lever 308 also ensures that the user can complete the entire transplanting process more accurately and stably without changing the grip posture, reducing mechanical errors during operation and improving overall operational precision.

[0028] In a preferred embodiment, to further improve the ease of operation and stability of the tool, the seedling collection tube 2 also includes a pedal 202. The pedal 202 is fixed to the upper side of the seedling collection tube 2 and is perpendicularly offset from the handle 101. The addition of the pedal 202 allows the user to apply additional force with their foot during use, thereby improving the efficiency and stability of operation. During the seedling collection process, the user can place one foot on the pedal 202 and use the force of the foot to assist the downward pressing action, reducing the burden on the hands and arms. This design not only makes operation more effortless but also provides a more uniform and stable force when applying pressure, avoiding uneven pressure or unstable operation caused by hand fatigue.

[0029] In a preferred embodiment, the pressure bar component 1 further includes two rubber grips 106, respectively fitted onto both ends of the handle 101. The addition of the rubber grips 106 significantly improves the tool's operational comfort and stability. During seedling extraction, the user needs to apply considerable downward pressure by gripping the handle 101; the rubber grips 106 effectively alleviate hand fatigue caused by prolonged operation. The rubber material itself has excellent anti-slip properties, allowing the user to firmly grip the tool even in wet or dirty environments, preventing slippage or improper control. The configuration of two rubber grips 106 provides a larger contact area and a more uniform pressure distribution, ensuring the user maintains good grip and control throughout the operation, thereby improving the accuracy and comfort of the work. Overall, the design of the rubber grips 106 makes the entire tool more user-friendly, especially during extended work sessions, effectively enhancing the user experience.

[0030] In a preferred embodiment, to further enhance the tool's applicability under different soil conditions, the lower part of the seedling tube 2 includes multiple circumferentially evenly distributed serrations 201. These serrations 201 play an important role in hard soil. When the soil is dense or relatively hard, the user can rotate the handle 101 to allow the serrations 201 of the seedling tube 2 to cut the soil, making it easier to penetrate the soil layer and successfully pick up the seedlings. The design of the serrations 201 effectively increases the friction of the cutting surface, making the seedling tube 2 smoother when penetrating the soil and less hindered by soil hardness. In addition, the even distribution of the serrations 201 ensures the uniformity of soil cutting, avoiding tool deviation or soil fragmentation caused by excessive force at one point. With this design, the user does not need to rely too much on strength and can complete the seedling picking operation more efficiently in different types of soil, especially when dealing with hard soil, which can greatly reduce the difficulty of operation and improve transplanting efficiency.

[0031] In a preferred embodiment, the pushing component 3 further includes a spring 309, located between the first rack and the grip 101, with both ends of the spring 309 fixed to the grip 101 and the first rack 301, respectively. This design makes operation smoother and more efficient. After the user pushes the seedling out, the spring 309, through its elasticity, automatically pushes the first rack 301 back to its initial position. This function not only reduces the steps required for manual adjustment during operation but also ensures that the tool is quickly ready for the next operation after each use, avoiding operational inconvenience caused by the rack jamming or failure to reset. The design of the spring 309 improves the tool's working efficiency, making operation more convenient, especially in high-frequency transplanting operations, where it can greatly save time and effort.

[0032] In the preferred design, the pressure bar component 1 also includes a protective cover 4, which is located on the first vertical rod 102 and covers the ejector component 3. The protective cover 4 is bolted to the first vertical rod 102 to ensure its stability and durability. The addition of the protective cover 4 is primarily to effectively prevent the ejector component 3 from being subjected to external impacts or contamination during use, thereby improving the tool's durability and service life. During transplanting operations, the ejector component 3 may come into contact with soil, mud, or other debris; the protective cover 4 prevents these substances from entering the gear system or spring 309 mechanism, avoiding jamming or damage. Simultaneously, the design of the protective cover 4 also serves as a dustproof and waterproof measure, effectively extending the tool's maintenance cycle and reducing maintenance frequency. Through the bolted connection, the protective cover 4 is securely connected to the first vertical rod 102, ensuring that it will not loosen or fall off due to operational vibrations or external forces during prolonged use.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
