[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] To address the technical challenges posed by uneven soil hardness and varied terrain, which lead to inconsistent seedling insertion depths, such as... Figures 1-9 As shown, the following preferred technical solutions are provided: A rice transplanter with adaptive seedling depth adjustment function includes a support frame 1, which can support and fix various components. A controller is installed on one side of the support frame 1 to control various electrical components. The controller is existing technology and is not shown in the figure. A push-pull rod 11 is provided inside the support frame 1. The push-pull rod 11 is convenient for manual handling and is used to control the direction of movement of the transplanter. Two seedling boxes 12 are arranged opposite each other inside the support frame 1. A seedling outlet 13 is opened through the seedling box 12 to facilitate the placement of seedlings. A seedling supply mechanism is provided inside the seedling box 12. The seedling supply structure is existing technology and is not shown in the figure. The seedling supply structure works with the seedling outlet 13 to continuously supply seedlings to the subsequent transplanting mechanism. A first drive component 2 is provided inside the support frame 1. A linkage component 3 is provided inside the support frame 1. The linkage component 3 is connected to the first drive component 2. Two dynamic adjustment components 4 are arranged opposite each other inside the linkage component 3. A seedling needle 5 is provided on one side of each dynamic adjustment component 4. A first detection component 6 is provided on one side of the seedling needle 5. The first detection component 6 can detect the depth at which the seedling is inserted into the soil by the seedling needle 5.

[0023] In use, the controller drives the first drive component 2 to activate the linkage component 3, which in turn causes the two dynamic adjustment components 4 to move the seedling needle 5 along a fixed path. This removes the seedlings from the seedling box 12 through the seedling outlet 13 and inserts them into the soil, achieving automatic transplanting. During the insertion of the seedling needle 5 into the soil, the soil provides a reaction force to the first detection component 6. Combined with the real-time detection of the first detection component 6, if the value of the first detection component 6 exceeds the benchmark range during the transplanting period from the moment the seedling needle 5 contacts the soil to the completion of transplanting, the dynamic adjustment component 4 quickly retracts a short distance, causing the seedling needle 5 to retract. A short distance is used to restore the value of the first detection component 6 to the reference range. When the value of the first detection component 6 is lower than the reference range, the dynamic adjustment component 4 quickly extends a short distance, causing the seedling needle 5 to extend a short distance, so that the value of the first detection component 6 returns to the reference range. This allows for real-time dynamic correction of the depth of the seedling needle 5 inserted into the soil, ensuring that the insertion depth of each seedling is within the range that meets the transplanting requirements. This ensures that the insertion depth of each seedling is consistent, thereby improving the quality of transplanting. After transplanting is completed, the dynamic adjustment component 4 quickly resets to prepare for the next transplanting.

[0024] The first drive assembly 2 is fixedly connected to the first traveling wheel 8 at both ends. The second detection assembly 9 is installed inside the support frame 1. The second detection assembly 9 can detect the front-back and left-right tilting states of the support frame 1. The second drive assembly 10 is provided on one side of the first traveling wheel 8. The telescopic assembly 20 is slidably connected inside the first traveling wheel 8. The telescopic assembly 20 is connected to the second drive assembly 10. The lifting assembly 30 is provided inside the support frame 1.

[0025] During the rice transplanting process, scenario 1: When the second detection component 9 detects that the left and right sides of the support frame 1 are tilted, the controller causes the second drive component 10 on the lower side to drive the telescopic component 20 to extend by the length corresponding to the second detection component 9, and causes the second drive component 10 on the higher side to drive the telescopic component 20 to retract by the length corresponding to the second detection component 9, so that the left and right positions of the support frame 1 are restored to a horizontal state. At this time, the value of the second detection component 9 returns to the reference range.

[0026] Scenario 2: When the second detection component 9 detects that the front and rear sides of the support frame 1 are tilted, the controller causes the lifting component 30 to extend or shorten according to the specific data of the second detection component 9, so that the front and rear sides of the support frame 1 are restored to a horizontal state. At this time, the value of the second detection component 9 returns to the reference range, which can facilitate the dynamic adjustment of the left and right or front and rear angles of the support frame 1 during the rice transplanting process, so as to avoid the seedlings from tilting when being inserted, thereby improving the quality of rice transplanting.

[0027] like Figure 1 and Figures 3-4 As shown, the first drive assembly 2 includes a mounting plate 21 fixedly connected to the support frame 1. A motor 22 is mounted on one side of the mounting plate 21. A rotating shaft 23 is fixedly connected to the output end of the motor 22. A first gear 24 is fixedly connected to one end of the rotating shaft 23. Several limit frames 25 are fixedly connected inside the support frame 1. A connecting shaft 26 is rotatably connected inside the limit frame 25. A second gear 27 is fixedly connected to the outer wall of the connecting shaft 26. The second gear 27 meshes with the first gear 24. A first sprocket 28 is fixedly connected to the connecting shaft 26. A chain 29 is driven by the first sprocket 28.

[0028] like Figures 1-5 As shown, the linkage component 3 includes a mounting rod 31 fixedly connected to the support frame 1. A rotating seat 32 is rotatably connected inside the mounting rod 31. A second sprocket 33 is fixedly connected to one end of the rotating seat 32. The second sprocket 33 is connected to the chain 29 for transmission. A first connecting rod 34 is fixedly connected to the other end of the rotating seat 32. A second connecting rod 35 is rotatably connected to one end of the first connecting rod 34. Two mounting seats 36 are arranged opposite each other inside the support frame 1. A third connecting rod 37 is rotatably connected to each of the two mounting seats 36. A fixing plate 38 is fixedly connected to one end of each of the two third connecting rods 37. The second connecting rod 35 is rotatably connected to the fixing plate 38.

[0029] like Figure 1 and Figure 5As shown, the dynamic adjustment component 4 includes a fixed frame 41 that is fixedly connected to the fixed plate 38. An electric push rod 42 is installed in the fixed frame 41. The response speed of the electric push rod 42 can match the rice transplanting speed to avoid adjustment lag. A slider 43 is fixedly connected to the movable end of the electric push rod 42. The slider 43 is slidably connected to the fixed frame 41. A seedling needle 5 is fixedly connected to one side of the slider 43. The seedling needle 5 is slidably connected to the fixed frame 41.

[0030] like Figures 5-6 As shown, the first detection component 6 includes a mounting sleeve 61 fixedly connected to one side of the seedling needle 5. A mounting cylinder 62 is fixedly connected inside the mounting sleeve 61. A pressure sensor 63 is installed inside the mounting cylinder 62. A spring 64 is fixedly connected to one side of the pressure sensor 63. A sliding column 65 is fixedly connected to one end of the spring 64. The sliding column 65 is slidably connected to the mounting cylinder 62. The pressure sensor 63 can detect the reaction force transmitted by the soil through the sliding column 65 and the spring 64 in real time, thereby determining whether the insertion depth of the seedling needle 5 meets the reference range. During the initial calibration, the conical rod 7 is made to contact simulated soil with different hardness conditions. The controller sets the pressure value corresponding to the insertion depth of the seedling needle 5 to the reference range. At the same time, the initial preload of the spring 64 is adjusted to ensure that the value of the pressure sensor 63 is stable under zero load, thereby completing the calibration.

[0031] like Figure 6 As shown, a tapered rod 7 is fixedly connected to one end of the sliding column 65. The tapered rod 7 facilitates the insertion of the seedling needle 5 into the soil, allowing the tapered rod 7 to be inserted into the soil more smoothly. At the same time, the reaction force of the soil can be transmitted to the pressure sensor 63 more accurately and stably through the spring 64, making it easier for the pressure sensor 63 to detect the force.

[0032] In use, the controller causes the motor 22 to drive the rotating shaft 23 and the first gear 24 to rotate. The meshing of the second gear 27 with the first gear 24 drives the second gear 27, the connecting shaft 26, and the first sprocket 28 to rotate. Through the transmission of the chain 29, the second sprocket 33 drives the rotating seat 32 to rotate within the mounting rod 31. The rotating seat 32 then drives the first connecting rod 34, the second connecting rod 35, and the third connecting rod 37 to move, causing the fixed plate 38, the dynamic adjustment component 4, and the seedling needle 5 to move along a fixed path. This allows the seedling needle 5 to remove the seedlings from the seedling box 12 through the seedling outlet 13 and insert them into the soil, achieving automatic transplanting. During the insertion of the seedling needle 5 into the soil, the soil provides a reaction force to the conical rod 7, the sliding column 65, and the spring 64, which is transmitted to the pressure sensor 63. 3. Real-time detection: During the transplanting period from when the seedling needle 5 contacts the soil to when the transplanting is completed, if the value of the pressure sensor 63 is higher than the reference range, the electric push rod 42 will quickly retract a short distance, causing the seedling needle 5 to retract a short distance as well, so that the value of the pressure sensor 63 returns to the reference range. If the value of the pressure sensor 63 is lower than the reference range, the electric push rod 42 will quickly extend a short distance, causing the seedling needle 5 to extend a short distance as well, so that the value of the pressure sensor 63 returns to the reference range. This allows for real-time dynamic correction of the insertion depth of the seedling needle 5 into the soil, ensuring that the insertion depth of each seedling is within the range that meets the transplanting requirements, thus ensuring consistent seedling insertion depth and improving the quality of transplanting. After transplanting is completed, the electric push rod 42 will quickly reset, preparing for the next transplanting.

[0033] To address the technical problem of seedlings tilting after being planted due to uneven field terrain, such as... Figure 1 , Figure 3 and Figures 7-10 As shown, the following preferred technical solutions are provided: like Figure 1 and Figure 3 As shown, the second detection component 9 includes a first protective shell 91 fixedly connected inside the support frame 1. An inclination sensor 92 is installed inside the support frame 1. The inclination sensor 92 is a two-axis inclination sensor 92, which can conveniently detect the tilt angles of the support frame 1 in the front-back and left-right vertical directions at the same time, and provide data for the subsequent leveling of the support frame 1. During the initial calibration, the support frame 1 is placed on a standard horizontal platform so that the inclination sensor 92 is in a horizontal state. The detection values ​​of the left-right and front-back are set as the reference range by the controller, thereby completing the calibration. The first protective shell 91 covers one side of the inclination sensor 92.

[0034] like Figure 1 and Figures 7-9As shown, the second drive assembly 10 includes a fixed cover 101 fixedly connected to one side of the first traveling wheel 8. A first servo motor 102 is installed inside the fixed cover 101. The first servo motor 102 has a self-locking function. A first threaded rod 103 is fixedly connected to the output end of the first servo motor 102. The first threaded rod 103 is rotatably connected to the first traveling wheel 8. A threaded plate 104 is threadedly connected to the first threaded rod 103. The threaded plate 104 is slidably connected to the inner wall of the fixed cover 101. Under normal conditions, the threaded plate 104 is located in the middle of the first threaded rod 103, which facilitates preparation for subsequent adjustments. A power supply 105 is installed inside the fixed cover 101, which provides stable power to the first servo motor 102.

[0035] like Figure 1 and Figures 7-9 As shown, the telescopic assembly 20 includes several movable rods 201 fixedly connected to one side of the threaded plate 104. The movable rods 201 are slidably connected to the first traveling wheel 8. A rotating column 202 is rotatably connected inside the movable rods 201. Several first anti-slip plates 203 are slidably connected inside the first traveling wheel 8. The first anti-slip plates 203 have inclined grooves 204. The rotating column 202 is rotatably connected to the inclined groove 204. Under normal conditions, the rotating column 202 is located in the middle of the inclined groove 204, which facilitates preparation for subsequent adjustments.

[0036] like Figure 1 and Figure 10 As shown, the lifting assembly 30 includes a support rod 301 fixedly connected to the support frame 1. A second servo motor 303 is installed on one side of the support rod 301. The second servo motor 303 has a self-locking function. A second protective shell 302 is fixedly connected to one side of the support rod 301. The second protective shell 302 covers one side of the second servo motor 303. A second threaded rod 304 is fixedly connected to the output end of the second servo motor 303. The second threaded rod 304 is rotatably connected to the support rod 301. A threaded frame 305 is threadedly connected to the second threaded rod 304. The threaded frame 305 is slidably connected to the support rod 301. A U-shaped frame 306 is fixedly connected to the bottom of the threaded frame 305. A second traveling wheel 307 is rotatably connected inside the U-shaped frame 306. Several second anti-slip plates 308 are fixedly connected to the outer wall of the second traveling wheel 307. Under normal conditions, the threaded frame 305 is located in the middle of the second threaded rod 304, which facilitates preparation for subsequent adjustments.

[0037] During rice transplanting, scenario 1: When the tilt sensor 92 detects a tilt on the left and right sides of the support frame 1, the controller causes the first servo motor 102 on the lower side to rotate forward, driving the first threaded rod 103 to rotate. This causes the threaded plate 104 to slide within the fixed cover 101, moving the moving rod 201 and causing the rotating column 202 to roll downward within the inclined groove 204. This causes the first anti-slip plate 203 to extend beyond the length corresponding to the tilt sensor 92 within the first traveling wheel 8, and causes the first servo motor 102 on the higher side to rotate in the opposite direction. The first threaded rod 103 rotates, causing the threaded plate 104 to slide within the fixed cover 101, which in turn moves the moving rod 201, causing the rotating column 202 to roll upward within the inclined groove 204. This causes the first anti-slip plate 203 to retract the length corresponding to the tilt sensor 92 within the first traveling wheel 8, thereby restoring the left and right positions of the support frame 1 to a horizontal state. At this time, the value of the tilt sensor 92 returns to the reference range. When the left and right positions are offset and dynamic adjustment is performed, the path offset of the rice transplanter is controlled within a reasonable range and will not affect the normal rice transplanting path.

[0038] Scenario 2: When the tilt sensor 92 detects that the front and rear sides of the support frame 1 are tilted, the controller causes the second servo motor 303 to drive the second threaded rod 304 to rotate, causing the threaded frame 305 to drive the U-shaped frame 306 to move. Based on the specific data from the tilt sensor 92, the support frame 1 is extended or shortened accordingly, so that the front and rear sides of the support frame 1 are restored to a horizontal state. At this time, the value of the second detection component 9 returns to the reference range, which can facilitate the dynamic adjustment of the left-right or front-back angle of the support frame 1 during the rice planting process, avoiding tilting of the seedlings during insertion and thus improving the quality of rice planting. If the value detected by the tilt sensor 92 exceeds the correctable range, an alarm is triggered to remind the user. The alarm is existing technology and is not shown in the figure.
