[0002] In agricultural production, seedling transplanting is a crucial step, and its efficiency and quality directly affect the growth and yield of crops. With the development of agricultural modernization, mechanized transplanting has gradually become more widespread. Whether it is large-scale farmland planting or precision horticulture, it can play an important role and powerfully promote the development of agricultural modernization.

[0003] Existing transplanting machinery typically uses rigid grippers when grasping seedlings, which can easily damage the seedling roots and reduce the survival rate. In addition, the digging depth adjustment function of the shovel is limited, which cannot flexibly adapt to the different transplanting depth requirements of different seedling varieties, and may affect the overall transplanting efficiency. Therefore, we have introduced a device that facilitates seedling transplanting. Utility Model Content

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This device for facilitating seedling transplantation utilizes the coordinated transmission of components such as the second digging shovel, the first fixing rod, and the ball in the extension assembly. When the second digging shovel is pushed, it causes the first fixing rod to slide. By utilizing the engagement of the ball with the arc-shaped groove and the elastic deformation of the second spring, the second digging shovel expands outward, thus facilitating deeper digging. Simultaneously, pulling the lever disengages the second digging shovel from the first digging shovel, making it easier to adapt to the different transplanting depth requirements of different seedling varieties, thereby effectively improving the versatility and operational efficiency of the equipment.

[0013] 2. This device, which facilitates seedling transplantation, employs a structure that uses an airbag ring in conjunction with clamping claws for transmission. When the second cylinder is activated, the base plate drives the clamping claws to approach the seedling. Simultaneously, the corrugated hose extends to deliver gas to the airbag ring, causing it to deform and wrap around and fix the seedling's roots and stems. This effectively avoids damage to the seedling's roots and stems and significantly improves the seedling survival rate. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1 - Figure 5 A device for facilitating seedling transplantation includes a support frame 1. One end of a connecting rod 2 is fixedly installed on the outer wall of the support frame 1, and the other end of the connecting rod 2 is rotatably sleeved with a drive shaft 3. A guide rod 14 is provided on the top of the support frame 1, and a flexible clamping assembly 15 is provided on the top of the support frame 1. A motor 10 is fixedly installed on the outer wall of the support frame 1, and a conveying cylinder 9 is fixedly installed on the outer wall of the support frame 1. A positioning plate 12 is provided on the top of the conveying cylinder 9. A turntable 11 is fixedly sleeved on the outer edge of the output shaft of the motor 10. A second cylinder 13 is provided on the top of the turntable 11. A first fixing plate 5 is fixedly sleeved on the outer wall of the drive shaft 3. One end of a turntable 4 is fixedly installed on the outer wall of the first fixing plate 5. A first digging shovel 7 is fixedly installed on the other end of the turntable 4. A first cylinder 6 is provided on the top of the first digging shovel 7, and an extension assembly 8 is provided on the outer wall of the first digging shovel 7.

[0024] In the above structure, by setting the extension component 8 and the flexible clamping component 15, the guide rod 14 is operated to grab the seedling and place it into the inner cavity of the second cylinder 13. Then, the motor 10 is started by the external power supply, and the outer edge of the output shaft of the motor 10 drives the turntable 11 to rotate. The seedling in the inner cavity of the second cylinder 13 will be opposite to the conveying cylinder 9 under the rotation of the second cylinder 13, and the seedling will fall into the inner cavity of the first cylinder 6 through the conveying cylinder 9. The turntable 4 will rotate under the drive of the first fixing plate 5. The rotation of the first fixing plate 5 will drive the first digging shovel 7 installed on the outer wall to rotate. At the same time, the extension component 8 on the outer wall of the first digging shovel 7 will first contact the ground to cultivate the ground to the depth required by the seedling. Then, the seedling in the inner cavity of the first cylinder 6 will fall into the cultivated pit, thus completing the transplanting.

[0025] In a preferred embodiment: the extension component 8 includes a fixing block 801, the outer wall of the fixing block 801 is provided with a second digging shovel 802, the inner wall of the fixing block 801 is provided with a first fixing rod 803 and a first spring 804, the outer wall of the first fixing rod 803 is provided with an arc groove 807, one end of a limiting plate 805 is fixedly connected to the outer wall of the first fixing rod 803, the other end of the limiting plate 805 is fixedly connected with a pull button 806, the inner wall of the first digging shovel 7 is fixedly installed with a first cylinder 808, and the inner cavity of the first cylinder 808 is provided with a second spring 809 and a ball 810.

[0026] In a preferred embodiment: one end of the first spring 804 is connected to the first fixing rod 803, and the other end is connected to the inner wall of the fixing block 801. The outer wall of the first fixing rod 803 is slidably fitted to the inner wall of the fixing block 801. The second digging shovel 802 is located on the outer wall of the first digging shovel 7. One end of the second spring 809 is connected to the ball 810, and the other end is connected to the inner wall of the first cylinder 808. The diameter of the ball 810 is larger than the diameter of the opening of the first cylinder 808, and it is adapted to the arc groove 807.

[0027] In the above structure, by setting the first fixing rod 803 and the sphere 810, when the seedling needs to dig holes of different depths, by positioning the second digging shovel 802 against the outer wall of the first digging shovel 7, and then pushing the second digging shovel 802, the first fixing rod 803 will slide along the inner wall of the first digging shovel 7 under the action of the second digging shovel 802. During this sliding motion, the outer wall of the first fixing rod 803 will contact the sphere 810. Then, under the compression of the first fixing rod 803, the sphere 810 will cause the second spring 809 to compress. As the first fixing rod 803 continues to move, when the sphere 810 slides to correspond to the inner wall of the arc-shaped groove 807, the sphere 810 will return to its original position within the arc-shaped groove 807 under the rebound of the second spring 809. Simultaneously, the sphere 810... The outer wall is fixed to the opening of the first cylinder 808, thereby extending the second digging shovel 802 to the outer wall of the first digging shovel 7. This allows the first digging shovel 7 to deepen the pit to a depth suitable for the seedling. When the seedling does not need a deep pit, it can pull the button 806, causing the button 806 to pull one end of the limiting plate 805 to move. The other end of the limiting plate 805 will drive the first fixing rod 803 to slide along the inner wall of the fixing block 801. The sliding first fixing rod 803 will cause the arc groove 807 to disengage from the ball 810. At the same time, the first spring 804 will be compressed under the displacement and sliding of the first fixing rod 803, thereby disengaging the second digging shovel 802 from the first digging shovel 7, thus facilitating the first digging shovel 7 to dig shallow pits.

[0028] In a preferred embodiment: the flexible clamping assembly 15 includes a first cylinder 151, a second fixing block 152 is fixedly installed on the telescopic end of the first cylinder 151, a second cylinder 153 is provided on the inner wall of the second fixing block 152, a corrugated hose 156 is provided on the outer wall of the second fixing block 152, a one-way valve 157 is provided on the top of the corrugated hose 156, an air pipe 158 is provided on the bottom of the corrugated hose 156, a base plate 154 is provided on the telescopic end of the second cylinder 153, a clamping claw 155 is provided on the bottom of the base plate 154, and an airbag ring 159 is provided on the bottom outer wall of the clamping claw 155.

[0029] In a preferred embodiment: the outer wall of the second fixing block 152 is slidably fitted to the inner wall of the guide rod 14, the outer wall of the base plate 154 is slidably fitted to the inner wall of the second fixing block 152, one end of the corrugated hose 156 overlaps with the top of the second fixing block 152, and the other end overlaps with the base plate 154. There are two air pipes 158, two airbag rings 159, and two clamping claws 155. Each air pipe 158, airbag ring 159, and clamping claw 155 is arranged as a group and is positioned opposite each other at the bottom of the base plate 154. One end of each air pipe 158 is connected to the air outlet of the corrugated hose 156, and the other end is connected to the air inlet of the airbag ring 159. The outer wall of the airbag ring 159 has a hole, and the hole is connected to the outlet of the airbag ring 159. The one-way valve 157 is connected to the air inlet of the corrugated hose 156.

[0030] In the above structure, by configuring the corrugated hose 156, air tube 158, and airbag ring 159, the activation of the second cylinder 153 controls the extension and retraction of the second cylinder 153. This causes the base plate 154 to move longitudinally along the inner wall of the second fixing block 152. This displacement causes the gripper 155 to move towards the seedling. Simultaneously, the displaced base plate 154 causes the folded and compressed corrugated hose 156 to extend synchronously. The extended corrugated hose 156 then synchronously releases gas through the one-way valve 157 at the top. The air tube 158 delivers gas to the inner cavity of the airbag ring 159. When the gripper 155 is activated, the airbag ring 159 deforms due to the gas in its inner cavity as the gripper 155 grasps the seedling. The deformed volume fixes the seedling's roots and stems. Then, by activating the first cylinder 151, the first cylinder 151 drives the second fixing block 152 to move laterally along the inner wall of the guide rod 14. This causes the seedling to move synchronously to the top of the second cylinder 13, thus transferring it to the next work station.

[0031] In a preferred embodiment: the top opening of the conveying cylinder 9 is located at the bottom of the second cylinder 13, and the bottom opening is located at the top of the first cylinder 6. The first cylinder 6, the first digging shovel 7, and the extension component 8 are considered as a set of movable components, and there are six such movable components, which are arranged in a circular array on the outer wall of the turntable 4.

[0032] In the above structure, the arrangement of the conveying cylinder 9, the second cylinder 13, and the first cylinder 6 causes the turntable 11 to rotate under the drive of the motor 10. When the second cylinder 13 rotates to correspond to the top opening of the conveying cylinder 9, the seedlings inside the second cylinder 13 will fall into the inner cavity of the first cylinder 6 through the inner cavity of the conveying cylinder 9. Then, the first fixing plate 5, driven by the transmission shaft 3, drives the six first digging shovels 7 and the extension components 8 arranged in a circular array on the outer wall to open up pits in the land. After the pits are opened, the seedlings will fall from the inner cavity of the first cylinder 6 into the pits.

[0033] Working principle: First, the second digging shovel 802 is aligned with the outer wall of the first digging shovel 7 and pushed, causing the second digging shovel 802 to drive the first fixing rod 803 to slide along the inner wall of the first digging shovel 7. During the sliding process, the first fixing rod 803 will squeeze the ball 810, causing the ball 810 to drive the second spring 809 to compress. When the ball 810 slides to the position corresponding to the inner wall of the arc groove 807, the second spring 809 rebounds and pushes the ball 810 into the inner wall of the arc groove 807, and at the same time, the ball 810 is pushed outward. The wall is fixed at the opening of the first cylinder 808, thereby expanding the second digging shovel 802 and increasing the depth of the pit opened by the first digging shovel 7. Conversely, pulling the button 806 causes the limiting plate 805 to drive the first fixing rod 803 to slide in the opposite direction, the arc groove 807 to disengage from the ball 810, and the first spring 804 to compress, thereby disengaging the second digging shovel 802 from the first digging shovel 7, making it easier for the first digging shovel 7 to open shallower pits, thus meeting the needs of different seedlings for transplanting depth.

[0034] Secondly, the second cylinder 153 is activated, causing its telescopic end to drive the base plate 154 to move longitudinally along the inner wall of the fixed block 152. The base plate 154 drives the gripping claw 155 to approach the seedling, while the folded corrugated hose 156 is stretched. During the extension of the corrugated hose 156, the one-way valve 157 delivers external gas through the air pipe 158 to the inner cavity of the air bag ring 159. Then, when the gripping claw 155 is activated to grasp the seedling, the gas in the air bag ring 159 causes it to deform. The deformed volume wraps around and fixes the seedling roots, achieving stable grasping of the seedling and avoiding damage.

[0035] By activating the first cylinder 151, the extension end of the first cylinder 151 causes the second fixing block 152 to move laterally along the inner wall of the guide rod 14, transferring the seedling to the top of the second cylinder 13. Then, the external power supply starts the motor 10, causing the output shaft of the motor 10 to drive the turntable 11 to rotate, which in turn drives the second cylinder 13 to rotate. When the seedling inside the second cylinder 13 is aligned with the top opening of the conveying cylinder 9, the seedling falls into the inner cavity of the first cylinder 6 by gravity. Then, the first fixing plate 5 drives the turntable 4 to rotate under the drive of the transmission shaft 3, causing the turntable 4 to drive the six sets of first cylinders 6, the first digging shovel 7 and the extension assembly 8 arranged in a circular array on their outer walls. The component rotates, causing the extended second digging shovel 802 to contact the ground first, digging a hole at the depth required by the seedling. After the hole is dug, the seedling inside the first cylinder 6 falls into the hole under the action of gravity, realizing the automated transplanting of seedlings and efficiently completing the seedling transplanting task.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
