Description

Technical Field

[0001] This invention relates to the field of intelligent agricultural power machinery technology, and in particular to an integrated rice planting and transplanting equipment with mulching. Background Technology

[0002] The intelligent integrated rice mulching and transplanting machine represents a significant breakthrough in modern agricultural technology. This equipment combines mechanical engineering, materials science, and intelligent sensor technology to achieve precise and coordinated operation of the mulching and transplanting processes, significantly improving the operational efficiency and ecological benefits of rice cultivation.

[0003] In existing technologies, to reduce the resistance of the seedling needles entering the soil, mulching and transplanting machines typically control the seedling needles to insert into the soil at an angle. During this angled insertion, the seedling needles pierce the mulch film at a sharp angle, thus maximizing the integrity of the mulch film. However, this approach has the following drawbacks:

[0004] During the process of pulling the seedling needles out of the soil, the needles are also moved at an angle. If the contact angle between the needles and the mulch film is not properly controlled during this process, the mulch film at the edge of the needles will be pulled upwards, causing the round hole to tear and expand into a crack, thus damaging the integrity of the mulch film. At the same time, during the process of pulling the needles at an angle, the soil's covering force on the seedling roots will be weakened due to the deviation in the pulling angle. If the needles are pulled out too quickly, they may bring out the already inserted seedlings, causing "floating seedlings" or the seedlings to tilt over, requiring manual replanting. Summary of the Invention

A connecting shaft is rotatably connected to the connecting housing. A second gear is fixedly connected to the connecting shaft. The first gear is used to transmit power to the second gear, which is located outside the connecting housing. A missing gear is fixedly connected to the connecting shaft, which is located inside the connecting housing. The seedling pusher is provided with teeth that mesh with the corresponding missing gear. A push plate is fixedly connected to the seedling pusher. A second spring is fixedly connected between the push plate and the connecting housing. A limit component is provided on the connecting housing to maintain the relative position of the connecting housing and the corresponding mounting housing.

[0008] More preferably, the seedling taker is provided with a seedling taking area, and the length of the teeth on the seedling pusher is greater than the length of the seedling taking area on the seedling taker.

[0009] More preferably, the limiting component includes symmetrically distributed first limiting pins, each of which is slidably connected to the connecting shell. The mounting shell is provided with symmetrically distributed limiting grooves, and the first limiting pins slide within the corresponding limiting grooves on the mounting shell. Symmetrically distributed fixing blocks are fixedly connected inside the connecting shell, and a third spring is fixedly connected between the fixing blocks and the corresponding first limiting pins. The first limiting pin is composed of a cylindrical part and a hemispherical part, and the depth of the limiting groove on the mounting shell is greater than the radius of the hemispherical part of the first limiting pin.

[0010] More preferably, an arc-shaped plate is fixed to the connecting block, the arc-shaped plate being used to press the connecting shell on the same connecting block.

[0011] More preferably, the mounting shell is provided with symmetrically distributed inclined surfaces, which are used to guide the corresponding first limiting pins. When the mounting shell is in a vertical state, the length of the projection of the inclined surface on the horizontal plane is greater than the length of the upper limiting groove on the horizontal plane.

[0012] More preferably, the limiting component further includes a movable frame, which is slidably connected to the corresponding connecting shell. The movable frame is fixedly connected to symmetrically distributed fixed plates. Each of the symmetrically distributed fixed plates has a first movable plate rotatably connected to its opposite side. A first torsion spring is fixedly connected between the first movable plate and the adjacent fixed plate. Each of the symmetrically distributed first movable plates has a second movable plate rotatably connected to its opposite side. A second torsion spring is fixedly connected between the second movable plate and the corresponding first movable plate. A connecting rope is fixedly connected between the fixed plate and the corresponding first limiting pin. The connecting rope passes through the corresponding fixed block.

[0015] More preferably, the maximum distance between the swing plate and the corresponding mounting shell is less than the maximum distance between the seedling extractor and the corresponding mounting shell.

[0016] The present invention has the following advantages: After a single transplanting is completed, the connecting shell causes the adjacent seedling picker to move upward relative to the adjacent mounting shell, thereby reducing damage to the transplanted seedlings and disturbance to the newly inserted seedlings, thus significantly reducing the seedling damage rate and seedling drift rate, and improving the uprightness and uniformity of the seedlings.

[0017] During the removal of the seedling extractor, the mounting shell scrapes and cleans the extractor, removing any residual soil or other impurities. This ensures that the extractor can proceed smoothly in subsequent seedling extraction processes and reduces the probability of extraction failure due to impurities remaining on the extractor.

[0018] The oscillating plate supports the stem of the seedling as the seedling picker moves, thereby extending the time the seedling is supported, ensuring that the seedling is in an upright position, and ensuring that the seedling roots can be firmly buried in the mud. Attached Figure Description

Detailed Implementation

[0030] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0031] Example 1

[0032] This embodiment discloses an integrated rice transplanter with mulching film. Considering that existing integrated rice transplanters with mulching film typically insert the seedling needles into the soil at an angle and pull them out at an angle during normal use, the angled needles come into contact with the mulch film, pulling it upwards and damaging its integrity. Furthermore, the soil's covering force on the seedling roots weakens due to the angle deviation during extraction, making it easy for the seedling needles to pull out the inserted seedlings, resulting in "floating seedlings" or seedlings tipping over. In contrast, this embodiment solves these problems through the following methods:

[0033] A type of integrated rice planting equipment with mulching and transplanting, such as Figures 1-6 As shown, it includes a connecting frame 1, a film covering module, a seedling storage mechanism 2, several connecting blocks 3 on one side of the connecting frame 1, a power component on the connecting blocks 3, symmetrically distributed transmission modules 4 on the connecting blocks 3, two connecting plates 5 on the transmission modules 4, a mounting shell 6 fixedly connected to the connecting plates 5, a connecting shell 7 slidably connected inside the mounting shell 6, a first spring 71 fixedly connected between the connecting shell 7 and the mounting shell 6, a fixed shell 8 fixedly connected to the connecting shell 7, the fixed shell 8 passing through the mounting shell 6 and slidably connected to it, a seedling picker 9 for picking up seedlings fixedly connected to the fixed shell 8, a seedling pusher 10 slidably connected to the fixed shell 8, and the seedling pusher 10 passing through the connecting shell 7 and slidably connected to it, the seedling pusher 10 fitting with the seedling picker 9 on the same fixed shell 8, and a transmission assembly on the mounting shell 6 for changing the position of the seedling pusher 10.

[0034] In the above scheme, the left side of the connecting frame 1 is connected to the existing traction device, and the film covering module on the connecting frame 1 is an existing device. The seedling storage mechanism 2 is located on the upper right side of the connecting frame 1 and is used to place rice seedlings. The specific number of connecting blocks 3 is selected by the staff. In the figure and text, three are used as an example. The power component and transmission module 4 on the connecting block 3 are existing devices. The transmission module 4 can be a gearbox or other device. The power component on the connecting block 3 drives the corresponding two connecting plates 5 to rotate synchronously through the transmission module 4. Under normal conditions, the first spring 71 is in a compressed state. The seedling picker 9 is an existing device used to pick up the seedlings and transplant them into the soil. The seedling pusher 10 is used to push the seedlings on the corresponding seedling picker 9 into the soil. Under normal conditions, the lower side of the seedling pusher 10 is flush with the lower side of the corresponding seedling picker 9, and the seedling pusher 10 blocks the lower port of the seedling picking area on the corresponding seedling picker 9.

[0035] Furthermore, such as Figures 4-6 As shown, the transmission assembly includes a drive shaft 11, which is disposed in the transmission module 4. The transmission module 4 transmits power from the power component to the drive shaft 11. The drive shaft 11 passes through the mounting housing 6 and is rotatably connected to it. A first gear 12 is fixedly connected to the drive shaft 11 and is located inside the mounting housing 6. A connecting shaft 14 is rotatably connected to the connecting housing 7. A second gear 13 is fixedly connected to the connecting shaft 14. The first gear 12 is used to transmit power to the second gear 13. The second gear 13 is located outside the connecting housing 7. A missing gear 15 is fixedly connected to the connecting shaft 14 and is located inside the connecting housing 7. The seedling pusher 10 is provided with teeth that mesh with the corresponding missing gear 15. A push plate 26 is fixedly connected to the seedling pusher 10. A second spring 16 is fixedly connected between the push plate 26 and the connecting housing 7. A limit component is provided on the connecting housing 7 to maintain the relative position between the connecting housing 7 and the corresponding mounting housing 6.

[0036] In the above scheme, the power component on the connecting block 3 drives the corresponding drive shaft 11 to rotate through the corresponding transmission module 4, so that the drive shaft 11 and the corresponding connecting plate 5 rotate relative to each other; the line connecting the center point of the first gear 12 and the center point of the corresponding second gear 13 is parallel to the central axis of the connecting shell 7, so that when the connecting shell 7 moves relative to the adjacent mounting shell 6, the second gear 13 can move synchronously with the connecting shell 7 and thus separate from the corresponding first gear 12; the missing gear 15 drives the seedling pusher 10 to move through its teeth during rotation, and compresses the corresponding second spring 16 in the process.

[0037] Furthermore, such as Figure 5 and Figure 6 As shown, the seedling taker 9 is provided with a seedling taking area, and the length of the teeth on the seedling pusher 10 is greater than the length of the seedling taking area on the seedling taker 9.

[0038] In the above scheme, the seedling taking area of ​​the seedling taker 9 is provided with symmetrically distributed inclined surfaces, and the distance between the two inclined surfaces gradually decreases from bottom to top.

[0039] Furthermore, such as Figures 4-7 As shown, the limiting component includes symmetrically distributed first limiting pins 17, which are all slidably connected to the connecting shell 7. The mounting shell 6 is provided with symmetrically distributed limiting grooves. The first limiting pins 17 slide in the corresponding limiting grooves on the mounting shell 6. Symmetrically distributed fixing blocks 18 are fixedly connected inside the connecting shell 7. A third spring 19 is fixedly connected between the fixing block 18 and the corresponding first limiting pin 17. The first limiting pin 17 is composed of a cylindrical part and a hemispherical part. The depth of the limiting groove on the mounting shell 6 is greater than the radius of the hemispherical part of the first limiting pin 17.

[0040] In the above scheme, under normal conditions, the first limiting pin 17 is located in the corresponding limiting groove on the corresponding mounting shell 6; the third spring 19 is always in a compressed and stored state to maintain the relative position of the first limiting pin 17; the depth of the upper limiting groove on the mounting shell 6 is limited to ensure that the first limiting pin 17 can connect and fix the corresponding mounting shell 6 and the corresponding connecting shell 7 under normal conditions.

[0041] Furthermore, such as Figure 2 As shown, an arc-shaped plate 191 is fixed to the connecting block 3. The arc-shaped plate 191 is used to press the connecting shell 7 on the same connecting block 3.

[0042] Furthermore, such as Figure 6 As shown, the mounting shell 6 is provided with symmetrically distributed inclined surfaces. The inclined surfaces on the mounting shell 6 are used to guide the corresponding first limiting pin 17. When the mounting shell 6 is in a vertical state, the length of the projection of the inclined surface on the horizontal plane is greater than the length of the projection of the upper limiting groove on the horizontal plane.

[0043] In the above scheme, the shape of the inclined surface on the mounting shell 6 is defined so that during the relative movement between the connecting shell 7 and the corresponding mounting shell 6, the first limiting pin 17 can be moved by the pressure of the corresponding inclined surface on the corresponding mounting shell 6.

[0044] Furthermore, such as Figures 6-8 As shown, the limiting component also includes a movable frame 20, which is slidably connected to the corresponding connecting shell 7. The movable frame 20 is fixedly connected to symmetrically distributed fixed plates 21. The opposing sides of the symmetrically distributed fixed plates 21 are rotatably connected to a first movable plate 22. A first torsion spring 23 is fixedly connected between the first movable plate 22 and the adjacent fixed plate 21. The opposing sides of the symmetrically distributed first movable plates 22 are rotatably connected to a second movable plate 24. A second torsion spring 241 is fixedly connected between the second movable plate 24 and the corresponding first movable plate 22. A connecting rope 25 is fixedly connected between the fixed plate 21 and the corresponding first limiting pin 17. The connecting rope 25 passes through the corresponding fixed block 18. The second movable plate 24 is located on the moving path of the push plate 26.

[0045] In the above scheme, the movable frame 20 can only slide up and down within the connecting shell 7.

[0046] Furthermore, such as Figure 7 As shown, the elastic coefficient of the first torsion spring 23 is greater than that of the third spring 19, the elastic coefficient of the second torsion spring 241 is less than that of the third spring 19, and the elastic coefficient of the second spring 16 is greater than that of the first torsion spring 23.

[0047] In the above scheme, the push plate 26 can contact and squeeze the two corresponding second moving plates 24 during the movement process, and at the same time ensure that the push plate 26 can drive the corresponding first limit pin 17 to move laterally by squeezing the corresponding second moving plates 24 during the downward movement process; and ensure that the seedling pusher 10 can drive the moving frame 20 to move downward during the downward movement of the push plate 26.

[0048] The specific workflow of the above scheme is as follows:

[0049] When it is necessary to use this device to plant rice, the staff first connects the connecting frame 1 to the traction device. After the connection is completed, a certain amount of rice seedlings are placed on the seedling storage mechanism 2. Then the traction device is started, and the traction device drives the connecting frame 1 to move to the left. During the movement, the film covering module on the connecting frame 1 covers the soil surface with mulch.

[0050] As the traction device moves the connecting frame 1 to the left, the operator activates the power components on the three connecting blocks 3. Each power component drives the two adjacent transmission modules 4 to rotate. During the rotation of the transmission module 4, the connecting plate 5 and the drive shaft 11 connected to it revolve around the revolution and simultaneously drive the connecting plate 5 and the drive shaft 11 to rotate on their own axis. The following description uses the movement process of the connecting plate 5 on the upper front side as an example:

[0051] During the rotation of the connecting plate 5 (in the process of revolution and rotation), it drives the mounting shell 6 to rotate synchronously. The mounting shell 6 drives all the parts inside it to rotate synchronously. Under the combined action of the transmission module 4 and the connecting plate 5, the angle between the seedling taker 9 and the horizontal plane gradually decreases as the transmission module 4 rotates. During this process, the connecting shell 7 and the lower side of the arc plate 191 are always in contact.

[0052] During the rotation of the drive shaft 11, the first gear 12 is driven to rotate. The first gear 12 meshes with and drives the second gear 13 to rotate, which in turn drives the connecting shaft 14 to rotate. The connecting shaft 14 drives the missing gear 15 to rotate. During the rotation of the missing gear 15, it meshes with the teeth on the seedling pusher 10, driving the seedling pusher 10 to move along the fixed shell 8. The seedling pusher 10 drives the push plate 26 to move synchronously. During the upward movement of the push plate 26, it compresses the second spring 16 to store force. During the movement of the seedling pusher 10, it moves along the seedling taker 9, thereby releasing the seedling taker area on the seedling taker 9. When the push plate 26 moves upward to contact the two second moving plates 24, the push plate 26 continues to move upward and squeezes the two second moving plates 24, causing the two second moving plates 24 to swing upward around their connection with the first moving plate 22 (the two second torsion springs 241 torsionally store force). After the push plate 26 moves upward to the position where it loses contact with the two second moving plates 24, the two second moving plates 24 are reset under the action of the corresponding second torsion springs 241.

[0053] When the seedling picker 9 revolves to the vicinity of the seedling, the angle between the seedling picker 9 and the horizontal plane reaches its minimum value (at this time, the seedling pusher 10 can still move relative to the seedling picker 9). At this time, the seedling picker 9, which was originally located on the right, rotates to the left. Thus, the transmission module 4 on the front side drives the seedling picker 9 to remove the seedling from the seedling storage mechanism 2 as it continues to rotate. The specific process can be referred to the seedling picking process of the existing rice transplanter, and will not be described in detail.

[0054] After the seedlings are taken, the transmission module 4 continues to drive the seedling taker 9 to revolve, causing the height of the seedling taker 9 to decrease continuously. At the same time, under the combined action of the transmission module 4 and the connecting plate 5, the angle between the seedling taker 9 and the horizontal plane gradually increases. After the lower side of the seedling taker 9 moves downward to contact the mulch film, the seedling taker 9 continues to move (during which the missing gear 15 still drives the seedling pusher 10 to move upward relative to the fixed shell 8), piercing the mulch film and gradually inserting it into the soil. When the seedling taker 9 moves downward to the lowest point, the angle between the seedling taker 9 and the horizontal plane reaches its maximum. At this time, the teeth on the seedling pusher 10 lose engagement with the missing gear 15, so that the seedling pusher 10 moves downward rapidly under the action of the second spring 16 (the seedling pusher 10 drives the pusher plate 26 to move downward synchronously). After the lower end of the seedling pusher 10 moves downward to contact the seedlings on the seedling taker 9, the seedling pusher 10 pushes the seedlings as it continues to move downward, thus pushing the seedlings on the seedling taker 9 into the soil.

[0055] When the push plate 26 moves downward to contact the upper side of the two second moving plates 24, the push plate 26 continues to move downward to press the two second moving plates 24, causing the second moving plates 24 to drive the adjacent first moving plates 22 to move downward. The first moving plates 22 drive the adjacent fixed plates 21 to move downward synchronously (the two fixed plates 21 jointly drive the moving frame 20 to move downward). During the downward movement, the fixed plates 21 pull the adjacent connecting ropes 25, causing the connecting ropes 25 to drive the adjacent first limiting pins 17 to move (during the movement, the first limiting pins 17 press the adjacent third springs 19 to store force). The two first limiting pins 17 approach each other. During this process, the first limiting pins 17 gradually separate from the adjacent limiting grooves on the mounting shell 6.

[0056] When both third springs 19 are compressed to their limit, the moving frame 20 moves downward to its lowest point, the distance between the two first limit pins 17 is at its minimum, and the first limit pins 17 lose contact with the mounting shell 6. At this time, the seedling pusher 10 continues to move downward, and the missing gear 15 still does not mesh with the teeth on the seedling pusher 10. Subsequently, the first spring 71 drives the connecting shell 7 to move upward synchronously, and the connecting shell 7 drives all its parts to move upward synchronously relative to the mounting shell 6, so that the first gear 12 and the second gear 13 separate (at this time, the missing gear 15 no longer rotates). At the same time, the seedling picker 9 is pulled upward from the soil, thereby reducing the degree of tearing of the mulch film, reducing the disturbance to the seedlings, and improving the uprightness and uniformity of transplanting. At the same time, the mounting shell 6 scrapes and cleans the seedling picker 9, removing the soil or other impurities remaining on the seedling picker 9, thereby ensuring that the seedling picker 9 can proceed smoothly in the subsequent seedling picking process and reducing the probability of seedling picking failure due to impurities remaining on the seedling picker 9.

[0057] As the first spring 71 drives the connecting shell 7 to move upward, the seedling pusher 10 continues to move downward relative to the connecting shell 7 under the action of the second spring 16. The push plate 26 presses the two first moving plates 22 through the two second moving plates 24, causing the two first moving plates 22 to swing downward around their connection with the adjacent fixed plate 21. During the rotation, the two first torsion springs 23 twist and store force until the push plate 26 moves downward to the position where it loses contact with the two second moving plates 24. The two first torsion springs 23 drive the adjacent second moving plates 24 to swing upward. The two first limiting pins 17 move in opposite directions under the action of the adjacent third springs 19 and extend out of the connecting shell 7. During the reverse movement, the two first limiting pins 17 drive the moving frame 20 to move upward relative to the connecting shell 7 through the two connecting ropes 25 until the seedling pusher 10 continues to move downward to the limit position under the action of the second spring 16. At this time, the lower side of the seedling pusher 10 is lower than the lower side of the seedling taker 9.

[0058] During the movement of the seedling pusher 10 and the removal of the seedling taker 9 from the soil, the transmission module 4 continues to drive the connecting plate 5 located on the left side to rotate under the action of the power component. After the connecting plate 5 located on the left side rotates to the right side, the transmission module 4 drives the connecting plate 5 to move upward, thereby driving the mounting shell 6 and its parts to move upward synchronously.

[0059] After the connecting shell 7 moves upward and contacts the arc plate 191, the arc plate 191 limits the connecting shell 7. At this time, the mounting shell 6 continues to move upward, causing the connecting shell 7 to be pressed down relative to the mounting shell 6 by the arc plate 191. During the resetting process, the two inclined surfaces on the mounting shell 6 press down on the corresponding first limiting pins 17, causing the two first limiting pins 17 to move closer to each other, thereby compressing and storing the two third springs 19. When both third springs 19 are compressed to their limit, the hemispheres of the two first limiting pins 17 are in contact with the inner wall of the mounting shell 6. At this time, the connecting shell 7 can still move downward relative to the mounting shell 6. The movement compresses and stores the first spring 71. When the two first limiting pins 17 move downwards to align with the corresponding limiting grooves on the mounting shell 6, the first limiting pins 17 are reset under the action of the third spring 19, thereby allowing the first limiting pins 17 to be reinserted into the corresponding limiting grooves on the mounting shell 6, fixing the mounting shell 6 and the connecting shell 7. That is, the connecting shell 7 is reset to its normal state relative to the mounting shell 6 (during this process, the first gear 12 and the second gear 13 re-mesh, and the drive shaft 11 continues to drive the second gear 13 to rotate through the first gear 12), for subsequent use. The above steps are repeated to continue planting the remaining rice seedlings.

[0060] After the staff uses this device to plant rice in a designated area (which is selected by the staff), the device is removed from the paddy field and cleaned and maintained in preparation for future use.

[0061] Example 2

[0062] Based on Example 1, we further optimized a rice planting mulch transplanter.

[0063] like Figure 4 , Figure 5 , Figure 9 and Figure 10 As shown, it also includes several auxiliary components. The auxiliary components are used to straighten the seedlings. The auxiliary components are set between the corresponding mounting shell 6 and the corresponding seedling picker 9. The auxiliary components include symmetrically distributed movable shells 27. The symmetrically distributed movable shells 27 are all slidably connected to the seedling picker 9. The symmetrically distributed movable shells 27 are all slidably connected to the corresponding mounting shell 6. The movable shell 27 is hinged to a swing plate 28. A third torsion spring 29 is fixed between the movable shell 27 and the corresponding swing plate 28. The mounting shell 6 is slidably connected to symmetrically distributed second limiting pins 30. A fourth spring 31 is fixed between the second limiting pin 30 and the mounting shell 6. The movable shell 27 is provided with a positioning groove. The second limiting pin 30 slides in the positioning groove on the corresponding movable shell 27. The second limiting pin 30 is composed of a hemispherical part and a cylindrical part. The depth of the positioning groove on the movable shell 27 is less than the diameter of the hemispherical part of the second limiting pin 30. The elastic coefficient of the fourth spring 31 is less than the elastic coefficient of the first spring 71.

[0064] In the above scheme, the swing plate 28 is located on the lower side of the adjacent movable shell 27; when the swing plate 28 is in contact with the corresponding seedling taker 9, the third torsion spring 29 is in a charged state; the two second limit pins 30 are symmetrically distributed front and back and are used to limit the corresponding movable shell 27.

[0065] Furthermore, such as Figure 9 As shown, the maximum distance between the swing plate 28 and the corresponding mounting shell 6 is less than the maximum distance between the seedling taker 9 and the corresponding mounting shell 6.

[0066] In the above scheme, the position of the swing plate 28 is limited so that the swing plate 28 supports the part of the seedling above the root.

[0067] The specific workflow of the above solution is as follows (this embodiment describes the movement process of the lower front connecting shell 7 as an example):

[0068] During the upward movement of the seedling picker 9 relative to the mounting shell 6, the seedling picker 9 moves upward relative to the two moving shells 27. When the seedling picker 9 moves upward to the position where it loses contact with the two swing plates 28, the two swing plates 28 swing under the action of the adjacent third torsion springs 29, reducing the distance between the lower sides of the two swing plates 28. When the lower inner edge of the two swing plates 28 swings to be flush with the lower end of the seedling picking area of ​​the seedling picker 9 (i.e., the predetermined support distance is reached between the two swing plates 28), the two swing plates 28 stop moving. The two swing plates 28 support the stem of the seedling during the upward movement of the seedling picker 9, thereby prolonging the time the seedling is supported, ensuring that the seedling is in an upright state, and ensuring that the seedling roots can be firmly buried in the mud.

[0069] When the seedling taker 9 moves upward to its limit position relative to the moving shell 27, the seedling taker 9 continues to move upward, driving the two moving shells 27 to move upward synchronously. During the movement, the moving shells 27 press the adjacent second limit pins 30, causing the two second limit pins 30 to move away from each other due to the pressure. At the same time, the second limit pins 30 press the adjacent fourth spring 31 during the movement, causing the fourth spring 31 to be compressed and store force until the connecting shell 7 moves upward to its limit position relative to the mounting shell 6, at which point the two moving shells 27 stop moving synchronously.

[0070] During the downward movement of the connecting shell 7 relative to the mounting shell 6, the seedling picker 9 moves downward relative to the two movable shells 27. After the seedling picker 9 moves downward to contact the two swing plates 28, the seedling picker 9 pushes the two swing plates 28 to move downward synchronously as it continues to move downward. The swing plates 28 drive the two movable shells 27 to move downward. When the two movable shells 27 move downward to the point where their upper positioning grooves are aligned with the adjacent second limiting pins 30, the second limiting pins 30 re-enter the positioning grooves of the adjacent movable shells 27 under the action of the adjacent fourth springs 31, and limit the movable shells 27 so that they no longer move downward (at the same time, the movable shells 27 move downward to their extreme positions). Then, the seedling picker 9 moves downward relative to the movable shells 27 and squeezes the two swing plates 28, causing the two swing plates 28 to swing. During the swing, the two third torsion springs 29 twist and store force for subsequent use, and the above steps are repeated to continue planting the remaining rice seedlings.
