[0002] The seedling transplanter is a professional equipment specially designed for transplanting seedlings from one location to another. The main function of this equipment is to improve the efficiency of transplanting operations while significantly reducing the labor intensity of workers. The common seedling transplanters on the market are usually composed of several core parts, including mobile devices, transplanting mechanisms, and control instruments. The mobile device is responsible for transferring the equipment between different operating areas to ensure the flexibility and convenience of transplanting operations. The transplanting mechanism is the part that directly acts on the seedlings. It can accurately complete a series of actions such as digging, carrying and implanting seedlings to ensure the survival rate and growth quality of seedlings during the transplantation process. The control instrument provides the operator with control over the entire transplanting process, making the operation more intuitive and simple, while also improving the safety of the operation.

[0003] For example, the patent with publication number CN1864471A provides a tree transplanting excavator. The tree transplanting excavator operates the separation and combination cylinder to make the left and right bucket shovels open, and operates the machine forward to make the tree to be transplanted enter the middle of the separated semicircular left and right bucket shovels, close the left and right bucket shovels, and then make the left and right bottom shovels cut into the soil from the left and right sides along an arc trajectory; then operate the left and right bucket shovel cylinders to press the left and right bucket shovels down and cut into the soil, cut off the rhizomes around the roots of the tree, and cut off its connection with the surrounding soil, lift the frame, lift the root ball of the cut tree off the ground, and synchronously lift and separate the left and right bottom shovels, and then separate the left and right bucket shovels to allow the root ball of the tree to slowly fall into a packaging barrel prepared in advance, thereby completing the excavation process of the tree.

[0004] When the above-mentioned existing seedling transplanter is used, a shovel is usually inserted into the soil to cut off the root system of the seedling, so that a soil ball is formed at the root system of the seedling, and then the soil ball is supported and moved by the transplanting mechanism to complete the transplanting of the seedling.

[0022] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] In order to solve the technical problem that the existing tree digging machine can only dig soil balls of fixed size and cannot adjust the digging size according to the radius of the tree, which limits the application scope of the transplanter, the present invention provides a seedling transplanter, which not only takes into account the accuracy of seedling clamping, but also takes into account the flexibility and efficiency of transplanting operations. By adjusting the size of the clamping area and the opening and closing action of the transplanting mechanism, the seedlings can be clamped and relaxed quickly and accurately, and the seedlings of different thicknesses can be transplanted adaptively, which greatly improves the automation and operation efficiency of seedling transplanting. In the process of seedling transplanting, for thicker seedlings, the transplanting mechanism can adaptively increase the shoveling range, which helps to retain the roots and stems of the seedlings and reduce the damage to the root and stem parts of the seedlings, thereby significantly improving the survival rate of the seedlings after transplanting; and for thinner seedlings, the transplanting mechanism can adaptively reduce the shoveling range, thereby reducing the volume of soil blocks required to be processed during excavation, thereby reducing the difficulty of excavation operations, making the entire transplanting process more efficient and convenient.

[0024] See also Figure 1 and Figure 2 The seedling transplanter comprises: a positioning structure 1 and a plurality of transplanting mechanisms 2, wherein the positioning structure 1 comprises at least two clamping members 11 and a driving member 12 arranged in a circular array, wherein the driving member 12 is connected to each of the clamping members 11 and is used to drive at least one clamping member to move 11 so as to adjust the size of the clamping area formed between each of the clamping members 11; each of the transplanting mechanisms 2 is respectively installed on the corresponding clamping members 11, and comprises a connecting member 21, a mounting member 22 and a shoveling member 23, wherein the mounting member 22 is connected to the driving member 12 through the connecting member 21, and each mounting member 22 is provided with a shoveling member 23, and when the driving member 12 pushes the clamping member 11 to adjust the size of the clamping area, the driving member 12 can drive the mounting member 22 to move synchronously through the connecting member 21 to adjust the size of the shoveling range of the shoveling member 23.

[0025] In this device, the clamping area formed between each clamping member 11 is used to clamp the seedlings, and the driving member 12 is used to push the clamping member 11 to move, so as to adjust the size of the clamping area and realize the clamping and loosening operation of the seedlings. The transplanting mechanism 2 includes a connecting member 21, a mounting member 22 and a shoveling member 23. The mounting member 22 is connected to the driving member 12 through the connecting member 21 so that the action of the transplanting mechanism 2 and the action of the clamping member 11 can be synchronized. The shoveling member 23 is used to insert into the soil and grab the seedlings to facilitate the transplantation of the seedlings. When the driving member 12 pushes the clamping member 11 to adjust the size of the clamping area, the mounting member 22 can perform an opening and closing action accordingly, so that the size of the shoveling range of the shoveling member 23 can be adjusted accordingly according to the thickness of the seedlings. This design makes the transplanting operation more flexible and efficient, so as to adapt to the clamping and transplantation of seedlings of different thicknesses.

[0026] See also Figures 1 to 3 In order to realize the integrated installation of each key component structure, in this embodiment, a mounting frame 3 is provided. The mounting frame 3 is designed to provide a stable support foundation for the entire device. It is installed on the transplanting vehicle 4. It can achieve up and down movement control with the help of the transplanting vehicle 4, so as to facilitate convenient operation during the transplanting process. The driving member 12 and the transplanting mechanism 2 are both installed on the mounting frame 3. In order to improve work efficiency and practicality, two groups of clamping members 11 are designed in this embodiment. The clamping members 11 are symmetrically arranged on both sides of the device, and an opening is formed between the two clamping members 11, so that the mounting frame 3 can be moved to the specified position and the clamping area of ​​the clamping member 11 is aligned with the seedlings. Each group of clamping members 11 is connected to the mounting frame 3 through the corresponding driving member 12, and the clamping member 11 can be independently controlled, thereby ensuring the stability and accuracy of the clamping member 11 when performing the transplanting task.

[0027] Among them, the clamping member 11 adopts an arc-shaped claw structure. The purpose of the arc-shaped design is to effectively increase the contact area with the circular seedlings, ensure that the seedlings are more stable when clamped, and reduce the damage to the seedlings. Furthermore, the driving member 12 includes a first cylinder 121, and the first cylinder 121 is fixedly mounted on the top surface of the mounting frame 3 through a mounting plate 122. The telescopic axis of the first cylinder 121 is designed to face the inner side of the mounting frame 3 and is fixedly connected to the claw structure of the clamping member 11. Through such a structural design, the telescopic movement of the first cylinder 121 can directly drive the claw structure to achieve precise clamping of the seedlings, which not only improves the efficiency of the operation, but also ensures the safety and stability of the seedlings during the clamping process.

[0028] In order to realize the linkage between the mounting member 22 and the driving member 12, in some possible embodiments, the connecting member 21 includes a fixed unit, a movable unit and a transmission unit. Specifically, the fixed unit is fixedly connected to the mounting frame 3, the movable unit is fixedly connected to the driving member 12, two transmission units are provided, and two ends thereof are respectively connected to the fixed unit and the movable unit, and one end of the two mounting members 22 is rotatably connected to the movable unit, and is respectively connected to the two transmission units. When the driving member 12 drives the movable unit to move relative to the fixed unit, the transmission unit will move accordingly, so that the mounting member 22 can swing relative to the movable unit. As the mounting member 22 swings, the position of the excavation component in the transplanting mechanism 2 is adjusted, so that it can be accurately positioned to the area to be excavated.

[0029] See also Figure 1 , Figure 2 and Figure 4In a specific embodiment of the present invention, the fixed unit includes a fixed plate 211 and a fixed frame 212, the movable unit includes a guide frame 213, a mounting frame 214 and a first connecting rod 215, and the transmission unit includes a second connecting rod 216 and a third connecting rod 217.

[0030] Specifically, the fixing plate 211 is fixed to the bottom surface of the mounting frame 3, and is correspondingly arranged below the mounting plate 122. The fixing frame 212 is fixedly arranged on the inner side of the fixing plate 211. One end of the guide frame 213 is slidably connected to the fixing frame 212. The sliding part of the guide frame 213 is arranged in parallel with the corresponding first cylinder 121. The guide frame 213 is fixedly connected to the driving member 12 through the first connecting rod 215, and can slide synchronously on the fixing frame 212 when the first cylinder 121 is extended or retracted. In this way, under the pushing action of the driving member 12, the guide frame 213 can be driven to move with it through the first connecting rod 215, and slide on the fixing frame 212. The mounting frame 214 is fixedly mounted on the fixed frame 212, and its two ends are rotatably connected to one end of the mounting member 22 respectively. One end of the second connecting rod 216 is rotatably connected to the guide frame 213, and the other end is rotatably connected to one end of the third connecting rod 217. The other end of the third connecting rod 217 is connected to the mounting member 22. In this way, when the guide frame 213 moves, the second connecting rod 216 can be driven to rotate by the third connecting rod 217, thereby driving the mounting member 22 to rotate to perform an opening and closing action.

[0031] During the execution process, the two cylinders extend synchronously, driving the clamping structure to approach the seedlings until the two clamping structures successfully fix the seedlings. During the operation of the cylinders, the guide frame 213 can be pushed to translate inward and slide on the fixed frame 212. Since the fixed frame 212 and the mounting frame 214 remain stationary, the guide frame 213 allows the second connecting rod 216 and the third connecting rod 217 to rotate relative to each other when it is active. While the third connecting rod 217 rotates, it synchronously drives the mounting member 22 to rotate, causing the mounting member 22 to rotate inward and contract, thereby adaptively reducing the range of excavation.

[0032] See also Figure 2 , Figure 4 , Figure 5 and Figure 6 In some possible embodiments, the transplanting mechanism 2 further includes an adjusting component 24, which is mounted on the mounting member 22 and has a driving end that moves along the length direction of the mounting member 22. The shoveling member 23 is mounted on the driving end.

[0033] In a specific embodiment of the present invention, the adjustment component 24 includes a tooth plate 241, a gear 242 and a drive motor. The tooth plate 241 is extended along the length direction of the mounting member 22, providing a moving track for the gear 242, and the gear 242 is tightly meshed with the tooth plate 241. The driving end of the drive motor is connected to the gear 242, and when the drive motor is started, it drives the gear 242 to rotate. The rotation of the gear 242 drives the tooth plate 241 to move along its length direction, thereby enabling the shoveling piece 23 installed on the driving end to adjust its position. This design allows the user to further adjust the position of the shoveling piece 23 on the mounting member 22 according to actual needs, ensuring that after the shoveling range is adjusted, the shoveling piece 23 can perform the seedling grabbing operation in the optimal position, thereby improving work efficiency and accuracy.

[0034] Further, in some embodiments, the design of the mounting member 22 adopts an arc structure. Specifically, the mounting member 22 includes a mounting rod 221 arranged in an arc shape. This arc design makes the entire device more consistent with the curved trajectory of actual operation, and improves the flexibility and adaptability of operation. Therefore, the tooth plate 241 is also arranged in an arc shape to match the shape of the mounting rod 221. The tooth plate 241 is installed in an arc groove opened at the bottom of the mounting rod 221, so that the tooth plate 241 can be closely matched with the mounting rod 221. Both sides of the central axis of the gear 242 are slidably connected to the side walls of the mounting rod 221, so that the gear 242 can slide smoothly along the mounting rod 221.

[0035] Preferably, in this embodiment, each transplanting mechanism 2 includes two mounting parts 22, that is, two symmetrical mounting rods 221 are rotatably arranged on the mounting frame 214, and the two mounting rods 221 are respectively located on both sides of the shoveling member 23. When the driving member 12 drives the clamping member 11 to move, the shoveling member 23 can be opened and closed under the drive of the connecting member 21, thereby adjusting the size of the shoveling range.

[0036] See also Figure 1 and Figure 5 In order to realize the digging and transplanting operation of the seedlings, in some possible embodiments, the shovel member 23 includes a shovel plate 231 and a telescopic drive unit, and the shovel plate 231 and the telescopic drive unit work together to ensure that the seedlings can be effectively dug and transplanted. Specifically, the telescopic drive unit is connected to the driving end of the adjustment component 24, and the driving end of the telescopic drive unit is connected to the shovel plate 231. When the telescopic drive unit is opened, it can drive the shovel plate 231 to perform telescopic movement, thereby performing the digging and transplanting operation of the seedlings.

[0037] In one specific embodiment, the telescopic drive unit includes a positioning frame 232 and a second cylinder 233. The positioning frame 232 is connected to the gear 242 through a connecting block. The second cylinder 233 is installed in the positioning frame 232. Its telescopic shaft extends outside the positioning frame 232 and is connected to the shovel plate 231, so that the second cylinder 233 can directly drive the shovel plate 231 to perform telescopic movement, so that the shovel plate 231 can be easily inserted into the soil, effectively grab the seedlings, and thereby achieve precise excavation and transplanting of the seedlings.

[0038] In the specific implementation process, when it is necessary to transplant the seedlings, first move the entire device to the specified position through the transplanting vehicle 4, then start the driving member 12, drive the clamping member 11 to approach the seedlings, and firmly clamp the seedlings through the clamping member 11. At the same time, the driving member 12 drives the mounting member 22 to move synchronously through the connecting member 21, so that the shoveling range of the shoveling member 23 is adaptively adjusted according to the thickness of the seedlings. Subsequently, start the second cylinder 233, adjust the position and angle of the shovel plate 231, so that it can be accurately inserted into the soil and grab the roots of the seedlings. Finally, through the up and down movement control of the transplanting vehicle 4, move the entire device together with the seedlings to a new planting position, release the clamping member 11, and complete the transplanting operation of the seedlings.

[0039] The present invention provides a positioning structure 1 and a transplanting mechanism 2. The design of the positioning structure 1 allows the size of the clamping area to be adjusted according to demand to adapt to the clamping of seedlings of different diameters, which not only ensures that the seedlings can be firmly clamped during operations such as transplanting to prevent sliding or falling, but also can accurately locate the excavation position. In addition, the opening and closing action of the transplanting mechanism 2 can adjust the size of the shoveling range of the shoveling member 23, and the shoveling range can be automatically positioned and adjusted according to the thickness of the seedlings, thereby making the transplanting operation more flexible and efficient.

[0040] The design of the device not only takes into account the accuracy of seedling clamping, but also takes into account the flexibility and efficiency of transplanting operations. By adjusting the size of the clamping area and the opening and closing action of the transplanting mechanism 2, the seedlings can be clamped and released quickly and accurately, and the seedlings of different thicknesses can be transplanted adaptively, which greatly improves the automation and operation efficiency of seedling transplanting.
