This utility model provides a seedling transplanting mechanism, relating to the field of agricultural equipment technology, including a frame, a drive unit, a digging shovel, and a clamping structure. A lifting frame is movably mounted on the frame along its height direction, and the drive unit is mounted on the frame. The digging shovel is connected to the lifting frame, and the clamping structure is connected to the lifting frame. The frame is fixed to a transplanting vehicle, and the seedling transplanting mechanism moves with the transplanting vehicle to the transplanting position. The drive unit drives the lifting frame to descend along the height direction of the frame, causing the digging shovel and clamping structure connected to the frame to move downwards together along the height direction of the frame. The digging shovel, under the action of the lifting frame, descends to the soil and digs into the soil to perform a hole-making operation, pre-forming transplanting holes in the soil. The clamping structure picks up the seedling and releases it when the lifting frame descends, allowing the seedling to fall into the transplanting hole on the digging shovel. The drive unit then drives the lifting frame to rise and reset, thus completing one seedling transplanting cycle.

[0020] Reference Figures 1 to 5 The following are several embodiments of the seedling transplanting mechanism of this utility model.

[0021] like Figures 1 to 5 As shown, the seedling transplanting mechanism of this utility model embodiment includes a frame 100, a driving component, a digging shovel 200, and a clamping structure 300; a lifting frame 110 is movably mounted on the frame 100 along the height direction of the frame 100; the driving component is mounted on the frame 100 and is used to drive the lifting frame 110 to rise or fall; the digging shovel 200 is connected to the lifting frame 110 and is used to perform the transplanting operation in the soil; the clamping structure 300 is connected to the lifting frame 110 and is used to clamp and release seedlings.

[0022] The frame 100 is fixed on the transplanting vehicle, and the seedling planting mechanism moves with the transplanting vehicle to the transplanting position. The drive unit drives the lifting frame 110 to descend along the height direction of the frame 100, which in turn drives the digging shovel 200 and the clamping structure 300 connected to the frame 100 to move downward together along the height direction of the frame 100. The digging shovel 200 descends into the soil under the action of the lifting frame 110 and digs into the soil to make holes in the soil to pre-form transplanting holes. The clamping structure 300 clamps the seedling and releases the seedling when the lifting frame 110 falls, so that the seedling falls into the transplanting hole formed by the digging shovel 200 in one descent. The drive unit then drives the lifting frame 110 to rise and reset, thus completing one seedling planting cycle. The digging shovel 200 can pre-drill holes in the soil to form transplanting holes. After the frame 100 moves forward with the transplanting vehicle, the digging shovel 200 continues to drill holes. At the same time, the clamping structure 300 releases the seedling into the transplanting hole formed by the digging shovel 200 in one fall, thus improving transplanting efficiency.

[0023] The transplanting vehicle moves along a set route, driving the seedling insertion mechanism forward. Along the direction of travel of the transplanting vehicle, the digging shovel 200 is positioned in front of the clamping structure 300 to pre-dig transplanting holes in the soil. For example, the lifting frame 110 descends, and the digging shovel 200 forms a first transplanting hole in the soil; the lifting frame 110 rises, and the transplanting vehicle moves to the next transplanting position; the lifting frame 110 descends, and the digging shovel 200 forms a second transplanting hole in the soil, and the clamping structure 300 subsequently descends to the first transplanting hole and releases the seedling into the transplanting hole; the lifting frame 110 rises, and the transplanting vehicle moves to the next transplanting position; the lifting frame 110 descends, and the digging shovel 200 forms a third transplanting hole in the soil, and the clamping structure 300 subsequently descends to the second transplanting hole and releases the seedling into the transplanting hole, and so on, to complete the transplanting of the seedlings. This embodiment of the invention uses a digging shovel 200 to pre-dig transplanting holes in the soil, and a clamping structure 300 to grip and release the seedlings, thus transplanting them into the soil. This allows for simultaneous digging and planting, improving transplanting efficiency. The seedlings can be plant seedlings, such as pineapple seedlings. Generally, the driving component is a cylinder or module.

[0024] like Figures 1 to 4As shown, in some embodiments, the seedling transplanting mechanism may include a transplanting vehicle, which includes a vehicle body, wheels, and a power mechanism. The frame 100 is mounted on the vehicle body, and the power mechanism drives the wheels to rotate, thereby enabling movement. The transplanting vehicle is prior art, and this embodiment of the present invention does not impose any particular limitations on it. The specific structure of the transplanting vehicle can be set with reference to the relevant structure of the seedling transplanting vehicle disclosed in Chinese Patent Publication No. CN107223533A. The seedling feeding mechanism may include a seedling delivery assembly, which includes a motor, a seedling storage box, a seedling storage tube, and a conveyor belt. Four rotating shafts are rotatably connected within the seedling storage box, and the conveyor belt is wound around these shafts. The motor is located within the seedling storage box and drives one of the rotating shafts to rotate, causing the conveyor belt to move within the seedling storage box. The seedling storage box has a seedling storage cavity and a seedling delivery channel located below the seedling storage cavity. The conveyor belt delivers seedlings at the bottom of the seedling storage cavity and has a seedling inlet. The seedling storage tube is located at the bottom of the seedling storage box and connects to the seedling delivery channel, situated at the first end of the seedling storage box. A push plate is located within the seedling delivery channel, connected to the conveyor belt, and positioned on the side of the seedling inlet away from the seedling storage tube. Seedlings are stacked in the seedling storage chamber to form multiple seedling layers. The conveyor belt moves away from the seedling storage tube, so that the seedling layer at the bottom of the seedling storage chamber is transferred to the seedling delivery channel through the seedling inlet. The conveyor belt moves towards the seedling storage tube, which drives the push plate to move in the seedling delivery channel and enter the seedling storage tube one by one. The seedling storage tube is set above the clamping structure 300. The bottom of the seedling storage tube is provided with an outlet with a switch valve. When the switch valve is opened, the clamping structure 300 is opened, and the seedlings in the seedling storage tube fall out. The clamping structure 300 clamps the seedlings. Under the action of the lifting frame 110, the clamping structure 300 descends to the transplanting hole and releases the seedlings, so that the seedlings fall into the transplanting hole.

[0025] like Figures 1 to 4 As shown, in some embodiments, the clamping structure 300 includes a clamping drive and two clamping members 310 disposed opposite each other. Each clamping member 310 includes a clamping portion 311 and a supporting portion 312 connected together. The clamping portion 311 is disposed on the side of the supporting portion 312 near the other clamping portion 311, and the clamping portion 311 has an abutment surface 3111 that abuts against the surface of the seedling. The supporting portion 312 is connected to the drive portion of the clamping drive. The clamping drive is disposed on the lifting frame 110 and is used to drive the two clamping members 310 closer together or further apart to clamp or release the seedling. The clamping drive drives the two clamping members to move closer together, so that the abutment surface 3111 tightly abuts against the surface of the seedling, thereby firmly clamping the seedling. The abutment surface 3111 can increase the contact area between the clamping portion 311 and the seedling, providing stable support for the clamping action and reducing the shaking of the seedling.

[0026] like Figures 1 to 4As shown, in some embodiments, multiple support portions 312 are provided, and the multiple support portions 312 are spaced apart along the height direction of the clamping member 310. This can ensure that the clamping member 310 supports each position of the seedling in the height direction, ensure the stable movement of the seedling, reduce the possibility of the seedling tilting or slipping during the clamping process, and increase the uprightness and success rate of seedling planting.

[0027] like Figures 1 to 4 As shown, in some embodiments, the support portion 312 includes a first support rod 3121 and a second support rod 3122 connected to each other. The first support rod 3121 and the second support rod 3122 are bent. The clamping portion 311 is connected to the first support rod 3121 and the second support rod 3122. When the clamping structure 300 clamps the seedling, the first support rods 3121 of the two clamping members 310 are arranged crosswise, and the second support rods 3122 of the two clamping members 310 are arranged crosswise.

[0028] Understandably, the first support rod 3121 and the second support rod 3122 are bent to improve the structural strength of the support portion 312, allowing the support portion 312 to stably support the clamping portion 311. The clamping portion 311 is connected to the first support rod 3121 and the second support rod 3122, and the bent design of the first support rod 3121 and the second support rod 3122 allows the clamping portion 311 to be subjected to support forces in multiple directions. The first support rod 3121 and the second support rod 3122 protrude from the clamping portion 311. 11, so that the first support rod 3121 and the second support rod 3122 can gather the leaves of the seedling (e.g., pineapple seedling); when the clamping structure 300 clamps the seedling, the first support rods 3121 of the two clamping members 310 are arranged crosswise, and the second support rods 3122 of the two clamping members 310 are arranged crosswise, so that the first support rods 3121 and the second support rods 3122 of the two clamping members 310 can avoid each other, ensuring the support force on the clamping member 310 while avoiding affecting the clamping effect.

[0029] like Figures 1 to 5 As shown, in some embodiments, the clamping drive includes a clamping motor, two synchronous shafts 330, and two meshing synchronous pulleys 320; the clamping part 311, the synchronous pulleys 320, and the synchronous shaft 330 are arranged in a one-to-one correspondence, the clamping part 311 and the synchronous pulleys 320 are fixed to the synchronous shafts 330, and the synchronous shafts 330 are rotatably connected to the lifting frame 110; the clamping motor is disposed on the lifting frame 110, and the output shaft of the clamping motor is connected to one of the synchronous pulleys 320; the clamping motor drives one of the synchronous pulleys 320 to rotate, and the synchronous pulley 320 drives the other synchronous pulley 320 to rotate synchronously in the opposite direction, thereby enabling the two clamping parts 310 to rotate towards or away from each other, thereby realizing that the two clamping parts 310 stably approach each other to clamp the seedlings or move away from each other to release the seedlings, increasing the symmetry and synchronicity of the clamping action of the clamping parts 310.

[0030] like Figures 1 to 4 As shown, in some embodiments, the contact surface 3111 is arc-shaped; when the clamping drive drives the two clamping members 310 to approach each other to clamp the seedling, the arc-shaped contact surface 3111 can form a larger clamping contact surface with the near-cylindrical seedling stem surface, thereby evenly distributing the clamping force to various parts of the seedling along the height direction of the seedling, reducing the damage to the seedling epidermis caused by the concentration of clamping force.

[0031] like Figures 1 to 4 As shown, in some embodiments, a limiting frame 400 is provided on the side of the lifting frame 110 near the clamping structure 300. The limiting frame 400 includes a limiting part 410, which is located above the clamping structure 300, and the limiting part 410 is provided with a limiting hole 411 for the seedling to pass through. When the clamping structure 300 clamps the seedling and moves down along the height direction of the frame 100 with the lifting frame 110 for planting, the limiting frame 400 located above the clamping structure 300 descends synchronously along the height direction of the frame 100. The limiting hole 411 on the limiting frame 400 will radially constrain and guide the seedling stem that passes through, reducing the possibility of the seedling tilting, shaking or lateral displacement during the planting process, so that the seedling can be planted in the soil in a near-vertical posture, thereby increasing the uprightness and quality of the planted seedling.

[0032] like Figures 1 to 4 As shown, in some embodiments, the limiting frame 400 further includes a receiving portion 420 hinged to the limiting portion 410; the receiving portion 420 can also be used to drive the seedling insertion mechanism to avoidance drive members, which are disposed on the lifting frame 110 and used to drive the receiving portion 420 to rotate relative to the limiting portion 410, so that the receiving portion 420 moves to the bottom of the clamping structure 300 to support the seedling, provide support for the seedling that is not yet stable, and reduce the possibility of the seedling tipping over; the limiting portion 410 can support the seedling that slides out of the seedling storage tube, so that the clamping structure 300 can stably clamp the seedling; when the clamping structure 300 clamps the seedling and moves down along the height direction of the frame 100 to insert the seedling, the avoidance drive members drive the receiving portion 420 to enter the retracted state to avoid; after the seedling is planted in the soil, the avoidance drive members drive the receiving portion 420 to rotate relative to the limiting portion 410, so that the limiting portion 410 moves to the bottom of the clamping structure 300.

[0033] like Figures 1 to 4As shown, in some embodiments, the digging shovel 200 includes a support block 210, a first loosening plate, and a second loosening plate 230. The support block 210 is connected to the lifting frame 110. The first and second loosening plates 230 protrude from the bottom of the support block 210 so that they can be inserted into the soil to make holes. The first loosening plate is bent and closely attached to the outer surface of the support block 210. The second loosening plate 230 is connected to the first loosening plate to improve the structural strength of the first loosening plate. The lifting frame 110... When the 10 moves downward along the height direction of the frame 100, the support block 210 connected to the lifting frame 110 drives the first loosening plate and the second loosening plate 230 to be inserted into the soil together; the first loosening plate, which is bent and close to the outer surface of the support block 210, can cut into the soil first and effectively break up the soil clods by using its bent structure. Then the second loosening plate 230 connected to the first loosening plate further loosens and expands the holes in the soil, thereby completing the loosening operation before the seedling is planted and creating a soil environment that is easy to plant seedlings.

[0034] like Figures 1 to 4 As shown, in some embodiments, two digging shovels 200 and two clamping structures 300 are respectively provided, with each digging shovel 200 and clamping structure 300 corresponding to one another, and the digging shovel 200 is located on the side of the lifting frame 110 away from the clamping structure 300; when the lifting frame 110 moves down along the height direction of the frame 100, the two digging shovels 200 first cut into and loosen the soil from the side away from their respective corresponding clamping structures 300; the two clamping structures 300 simultaneously clamp the seedlings and insert the seedlings they clamp into the transplanting holes that have been pre-drilled in their respective digging shovels 200; so that loosening the soil and transplanting the seedlings are completed in an orderly manner at two workstations, and the digging shovels 200 and the clamping structures 300 do not interfere with each other but cooperate closely, thereby improving the efficiency of transplanting.

[0035] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined in this application.
