Description

Technical Field

[0001] The invention belongs to the technical field of pot seedling transplanting machines, and in particular relates to an integrated pot seedling transplanting device. Background Art

[0002] The seedling pot transplanter is an automated agricultural device primarily used to efficiently and precisely transplant seedlings (seedlings with intact root tufts) from seedling trays into the field. Its core function is to mechanically complete the seedling removal, transportation, and planting process, replacing traditional manual transplanting. This significantly improves operational efficiency (up to 18-20 times that of manual labor), while minimizing root damage, shortening the seedling acclimatization period, and increasing crop survival rates. This device is widely used in large-scale cultivation of crops such as vegetables, rice, and flowers, and is particularly effective in high-cropping index crops like leafy vegetables.

[0003] Traditional transplanter spacing adjustment requires replacing sprockets or adjusting the position of mechanical components. For example, patent CN203661572U discloses a transplanter spacing adjustment device, comprising a sprocket mechanism I and a sprocket mechanism II. A closed-loop chain is mounted on a corresponding set of sprockets on sprocket mechanism I and sprocket mechanism II. The chain is equipped with an automatic tensioning mechanism. The torsional torque of a tensioning spring causes the tensioning wheel to rotate about its axis, automatically tensioning the chain. A wheel-changing mechanism I is located on one side of sprocket mechanism I for adjusting the position of the chain on sprocket mechanism I; a wheel-changing mechanism II is located on one side of sprocket mechanism II for adjusting the position of the chain on sprocket mechanism II. This device simplifies spacing adjustment and reduces adjustment time. When the transplanter needs to change the spacing, there is no need to disassemble or install the drive wheel or replace or adjust the relative positions of the sprockets. This eliminates the tedious disassembly and assembly process for adjusting the spacing, saving time and effort, and providing excellent performance.

[0004] Although the transplanting spacing adjustment device used in this transplanter simplifies the chain wheel changing process through the sprocket mechanism and the tensioning spring, the adjustment process requires stopping the operation and manually disassembling some mechanical structures (such as replacing the sprocket or adjusting the transmission ratio), and changing the wheel adjustment shaft. The above problems will lead to low efficiency of the device. Summary of the Invention

For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to the specific circumstances.

[0034] Please see Figures 1 to 11 , an integrated pot seedling transplanting device, comprising The mobile body 100 has a driving mechanism 110, which drives the mobile body 100 to move. Specifically, the driving mechanism 110 includes a driving wheel body, a driven wheel body and a driving assembly. The driving wheel body and the driven wheel body are installed at the bottom of the mobile body 100. The driving assembly is connected to the driving wheel body to drive the driving wheel body to move. The movement of the driving wheel body drives the driven wheel body to move, and then drives the mobile body 100 to move.

[0035] Speed ​​change mechanism 200, see Figure 1 and Figure 6 , installed on the mobile body 100, and connected to the driving mechanism 110; specifically, the speed change mechanism 200 is connected to the driven wheel body, and the driven wheel body moves to drive the speed change mechanism 200 to rotate. The speed change mechanism 200 is a device with a speed change function. After the rotation speed of the driven wheel body is transmitted to the speed change mechanism 200, the rotation speed is changed by the speed change mechanism 200 and then output as a second rotation speed again; and the speed change mechanism 200 can change speed to output different rotation speeds.

[0036] The first transmission rod mechanism 300, see Figure 6 , installed on the mobile body 100, the first transmission rod mechanism 300 is connected to the speed change mechanism 200, and the speed change mechanism 200 drives the first transmission rod mechanism 300 to transmit; the first transmission rod mechanism 300 can realize direction change and transmission, and the second rotation speed output by the speed change mechanism 200 drives the first transmission rod mechanism 300 to move.

[0037] The second transmission rod mechanism 400 is installed on the mobile body 100 and is in transmission connection with the first transmission rod mechanism 300 . The rotation of the first transmission rod mechanism 300 drives the rotation of the second transmission rod mechanism 400 .

[0038] Seedling planting mechanism 500, see Figure 7 and Figure 8 , including a vertical swing component 510 and a duckbill planting component 520, the vertical swing component 510 is connected to the first transmission rod mechanism 300, driving the vertical swing component 510 to swing vertically, the duckbill planting component 520 is connected to the vertical swing component 510, and the duckbill planting component 520 is connected to the first transmission rod mechanism 300, and the duckbill planting component 520 can be opened or closed within the interval time period; specifically, the first transmission rod mechanism 300 is in the rotation process In the process, the vertical swing component 510 will be driven to swing up and down in the vertical direction. When the vertical swing component 510 swings upward, it will drive the duckbill planting component 520 to swing upward. At this time, the duckbill planting component 520 is in a closed state. When the vertical swing component 510 swings downward, it will drive the duckbill planting component 520 to swing downward. At this time, the first transmission rod mechanism 300 pulls the duckbill planting component 520, and the duckbill planting component 520 is in an open state.

[0039] See the pot seedling placing mechanism. Figure 5 , including a rotating component and several seedling potting components 620, the rotating component is installed on the mobile body 100, the rotating component is connected to the second transmission rod mechanism 400, the second transmission rod mechanism 400 drives the rotating component to rotate, and several seedling potting components 620 are arranged in a circular array at a preset interval on the rotating component, and the seedling potting components 620 are located above the seedling potting planting mechanism 500, and seedlings are placed on the seedling potting components 620, and manual seedling placement is adopted.

[0040] The exercise process includes: The seedling pots are manually placed on the seedling potting assemblies 620, the mobile body 100 is started, the driving assembly drives the driving wheel body to move, and the driving wheel body drives the driven wheel body to move. The speed change mechanism 200 is connected to the driven wheel body, thereby driving the speed change mechanism 200 to rotate. The speed change mechanism 200 outputs a second rotation speed and drives the first transmission rod mechanism 300 to move. The process of the first transmission rod mechanism 300 driving the seedling pot planting mechanism 500 to move is mainly divided into a seedling collecting process and a seedling placing process; see Figure 7, the seedling collection process is as follows: the first transmission rod mechanism 300 rotates, driving the vertical swing component 510 to swing upward, and the vertical swing component 510 drives the duckbill type planting component 520 to swing upward, and the duckbill type planting component 520 is in a closed state. When the first transmission rod mechanism 300 rotates, it drives the second transmission rod mechanism 400 to rotate, and the second transmission rod mechanism 400 drives the rotating component to rotate, and drives the seedling pot holding component 620 to rotate through the rotating component. When the seedling pot holding component 620 moves to the top of the duckbill type planting component 520, the bottom of the seedling pot holding component 620 opens. At this time, the duckbill type planting component 520 rises to the highest point, and the seedlings in the seedling pot holding component 620 fall into the duckbill type planting component 520, and the seedling pot holding component 620 completes the seedling collection process; see Figure 8 The seedling planting process is as follows: during the seedling pot dropping process, the vertical swing assembly 510, driven by the first transmission rod mechanism 300, swings vertically downward, driving the duckbill planting assembly 520 downward. After the duckbill planting assembly 520 moves downward by a preset distance, the first transmission rod mechanism 300 drives the duckbill planting assembly 520 to open, causing the seedling pots in the duckbill planting assembly 520 to drop out and land on the ground or in the furrow, completing the seedling planting process. While the duckbill planting assembly 520 is descending, the first transmission rod mechanism 300 continues to drive the second transmission rod mechanism 400 to rotate, which indirectly drives the seedling pot holding assembly 620 to rotate, causing the seedling pot holding assembly 620 filled with seedlings to rotate toward the top of the duckbill planting assembly 520, waiting for the next seedling drop. This reciprocating motion is repeated in sequence to achieve the planting of seedling pots.

[0041] Through the cooperation among the speed change mechanism 200, the first transmission rod mechanism 300, the second transmission rod mechanism 400, the seedling pot planting mechanism 500 and the seedling pot holding mechanism, a rapid seedling collection and release process for the seedling pots is achieved; and during the planting process, it is only necessary to manually place the seedling pots in the seedling pot holding mechanism, and no manual secondary seedling arrangement is required, thereby avoiding damage and dispersion of the seedling pot roots; furthermore, by adjusting the speed change mechanism 200, the transmission speed of the transmission rod mechanism is changed, and then the seedling pot spacing is adjusted to achieve self-adaptive seedling pot planting; in addition, the seedling pot transplanter is an integrated transplanter, which does not require manual adjustment of the sprocket and the rotating shaft, and does not require manual adjustment of the transmission ratio, thereby improving the utilization efficiency of the transplanter.

[0042] In one possible embodiment, see Figure 6The variable speed mechanism 200 includes an infinitely variable gearbox 210, a driving pulley 220, an input pulley 230 and an output pulley 240. The infinitely variable gearbox 210 is installed on the mobile vehicle body 100. The infinitely variable gearbox 210 is a conventional variable speed device. The transmission ratio can be changed by the variable speed device to change the driving speed and the seedling planting speed. The driving pulley 220 is sleeved on the rotating shaft of the mobile vehicle body 100. Specifically, the driving pulley 220 is connected with the connecting shaft of the driven pulley body. The input pulley 230 is sleeved on the input shaft of the infinitely variable gearbox 210. The output pulley 240 is sleeved on the output shaft of the infinitely variable gearbox 210. The driving pulley 220 is connected with the input pulley 230 through a first transmission chain 250. The output pulley 240 is connected with the first transmission lever mechanism 300 through a second transmission chain 260. The transmission ratio is changed by adjusting the infinitely variable gearbox 210. The speed of the connecting shaft of the driven pulley body is transmitted to the input pulley 230 through the first transmission chain 250. After the transmission ratio is changed by the infinitely variable gearbox 210, the output of the output shaft of the infinitely variable gearbox 210 is adjusted to a second rotating speed. The output pulley 240 is transmitted to the first transmission lever mechanism 300 through the second transmission chain 260. The transmission ratio of the infinitely variable gearbox 210 is adjusted to change the spacing of the pot seedling planting mechanism 500 to make the spacing of the pot seedlings uniform.

[0043] In one possible embodiment, referring to Figure 6 The first transmission lever mechanism 300 includes a first shaft seat 310, a first driving shaft 320, a driven pulley 330, an eccentric assembly 340 and a first transmission gear 350. The first shaft seat 310 is provided in pairs. The first shaft seat 310 is installed on the mobile vehicle body 100. The first driving shaft 320 is rotatably sleeved on the first shaft seat 310. A pair of first shaft seats 310 can keep the sleeved driving shaft balanced to prevent the driving shaft from swinging during rotation.

[0044] Specifically, the shaft seat is provided with a rotating bearing. When the driving shaft is sleeved on the shaft seat, the driving shaft can rotate in the shaft seat.

[0045] Referring to Figure 7The eccentric component 340 is arranged at the other end of the first driving shaft 320. The eccentric component 340 is connected to the vertical swing component 510. The eccentric rotation of the eccentric component 340 drives the vertical swing component 510 to swing vertically. It should be further explained that the vertical swing amplitude of the vertical swing component 510 is related to the eccentric distance of the eccentric component 340. When the eccentric distance is larger, the vertical swing amplitude of the vertical swing component 510 is larger, and vice versa. Therefore, the vertical swing amplitude of the vertical swing component 510 can be adjusted by replacing or adjusting the eccentric distance of the eccentric component 340 so that the vertical swing component 510 reaches a swing height or amplitude in the vertical direction.

[0046] The eccentric component 340 is connected to the duckbill planting component 520, and the eccentric rotation of the eccentric component 340 drives the duckbill planting component 520 to open or close. During the vertical downward movement of the duckbill planting component 520, the eccentric component 340 drives the duckbill planting component 520 to open. When the duckbill planting component 520 moves down to the lowest point, the duckbill planting component 520 is in the maximal open state. During the vertical upward movement of the duckbill planting component 520, the duckbill planting component 520 gradually closes until it is completely closed.

[0047] The first transmission tooth 350 is sleeved on the first driving shaft 320 and fixed to the first driving shaft 320 by a key or welding method to prevent the first transmission tooth 350 and the first driving shaft 320 from rotating relative to each other. The first transmission tooth 350 cooperates with the second transmission rod mechanism 400 to transmit power, thereby driving the second transmission rod mechanism 400 to rotate.

[0048] In a preferred embodiment, see Figure 7 The eccentric assembly 340 includes a cam 341, an eccentric rod 342, and a pullback member 343. The cam 341 is sleeved on one end of the first driving shaft 320. The rotation of the first driving shaft 320 drives the cam 341 to rotate. One end of the eccentric rod 342 is rotatably disposed on the outer edge of the cam 341. The other end of the eccentric rod 342 is rotatably connected to the vertical swing assembly 510. Specifically, an eccentric protrusion is provided on the outer edge of the cam 341. The eccentric rod 342 is rotatably sleeved with the eccentric rod 342. When the cam 341 rotates, it drives the eccentric rod 342 to move eccentrically, and the movement of the eccentric rod 342 drives the vertical swing assembly 510 to move. The pullback member 343 is rotatably disposed on the mobile body 100. One end of the pullback member 343 is slidably overlapped with the outer end surface of the cam 341.

[0049] In a preferred embodiment, see Figure 7 The pull-back member 343 comprises a hinged seat 3431, an extension rod 3432 and a roller 3433. The hinged seat 3431 is arranged on the moving vehicle body 100. One end of the extension rod 3432 is rotatably connected with the hinged seat 3431. The other end of the extension rod 3432 is rotatably connected with the roller 3433. The roller 3433 is located near the cam 341. The roller 3433 and the extension rod 3432 are located above the cam 341. The roller 3433 is in rolling contact with the outer end surface of the cam 341. When the cam 341 rotates, the protruding part of the cam 341 is in contact with the roller 3433. The roller 3433 rolls on the outer end surface of the protruding part of the cam 341. Since the roller 3433 is located above the cam 341, the protruding part of the cam 341 lifts the roller 3433. Since the roller 3433 is located at one end of the extension rod 3432, one end of the extension rod 3432 is lifted upward. The other end of the extension rod 3432 rotates around the hinged seat 3431. When the roller 3433 moves off the protruding part of the cam 341, the roller 3433 is lowered due to gravity. One end of the extension rod 3432 moves downward and returns to the initial rolling position.

[0050] It should be further explained that the protruding part of the cam 341 is arranged in a staggered manner with the eccentric protrusion of the cam 341. The staggered arrangement position is adjusted according to the rotating position of the eccentric rod 342 and the lifting position of the roller 3433. The seedling planting method can be used to plant seedlings in a furrow or in soil.

[0051] Specifically, referring to Figure 7 , Figure 8 and Figure 9 , the seedling planting method is used to plant seedlings in a furrow (without breaking soil by the duckbill planting assembly 520, and the duckbill planting assembly 520 only plants seedlings). The distance between the eccentric protrusion of the cam 341 and the connecting line of the axis of the cam 341 is X1. The distance between the starting position of the protruding part of the cam 341 and the connecting line of the axis of the cam 341 is X2. The distance between the ending position of the protruding part of the cam 341 and the connecting line of the axis of the cam 341 is X3. The included angle between X1 and X2 is 90°-110°. The included angle between X1 and X3 is 160°-180°.

[0052] Specifically, the seedlings in the pots are planted in the furrows in a manner such that the angle between X1 and X2 is 100°, and the angle between X1 and X3 is 170°. When the eccentric rod 342 drives the vertical swing component 510 to move upward, that is, when the eccentric rod 342 indirectly drives the duckbill planting component 520 to move toward the side close to the seedling pot holding component 620, the raised portion of the cam 341 is not in contact with the roller 3433 (in a distant state), and the pullback member 343 will not pull the duckbill planting component 520 to be in an open state. When the seedling pot holding component 620 drops the seedling pot on the duckbill planting component 520, the seedling pot will be stored in the duckbill planting component 520 and will not fall on the ground, thereby preventing the seedling pot from being damaged; when the eccentric rod 342 drives the vertical swing component 510 to move downward, that is, when the eccentric rod 342 indirectly drives the duckbill planting component 520 toward a side away from the seedling pot holding component 620 When one side moves, or in other words, when the duckbill planting component 520 approaches the ground, the raised portion of the cam 341 contacts the roller 3433 (in a close state), and the raised portion of the cam 341 will lift the roller 3433, and then the extension rod 3432 of the pullback member 343 will pull the duckbill planting component 520, so that the duckbill planting component 520 is in a gradually opened state. When the duckbill planting component 520 moves to the lowest point, the raised portion of the cam 341 lifts the roller 3433 to the maximum height, and the duckbill planting component 520 also opens to the maximum width. After the seedlings in the duckbill planting component 520 fall to the ground or the furrow, since the seedlings fall close to the ground, they will not cause major damage to the seedlings, thereby ensuring the integrity of the seedlings and facilitating their growth.

[0053] Specifically, the method of planting seedlings in the soil is as follows (the duckbill planting component 520 is required to break the soil, and the duckbill planting component 520 is required to both break the soil and plant the seedlings): the distance between the eccentric protrusion of the cam 341 and the axis of the cam 341 is Y1, the distance between the starting position of the protrusion of the cam 341 and the axis of the cam 341 is Y2, and the distance between the ending position of the protrusion of the cam 341 and the axis of the cam 341 is Y3. The angle between Y1 and Y2 is 160°-180°, and the angle between Y1 and Y3 is 90°-110°.

[0054] Specifically, the method of planting the seedlings in the soil is as follows: the angle between X1 and X2 is 100 degrees, and the angle between X1 and X3 is 170 degrees. When the eccentric rod 342 drives the vertical swing assembly 510 to move upward, that is, when the eccentric rod 342 indirectly drives the duckbill planting assembly 520 to move toward the side close to the seedling holding assembly 620, the raised portion of the cam 341 is not in contact with the roller 3433 (in a distant state), and the pullback member 343 will not pull the duckbill planting assembly 520 to an open state. When the seedling holding assembly 620 drops the seedlings in the duckbill planting assembly 520, the seedlings will be stored in the duckbill planting assembly 520. In the process of the eccentric rod 342 driving the vertical swing component 510 to move downward, that is, the eccentric rod 342 indirectly drives the duckbill type planting component 520 to move toward the side away from the seedling holding component 620, or in other words, the duckbill type planting component 520 approaches the soil, and as the duckbill type planting component 520 moves, it will penetrate into the soil and be at a preset depth, such as 8-15 cm. The duckbill type planting component 520 will poke a planting pit. At this time, the duckbill type planting component 52 0 moves to the lowest point, and the duckbill planting component 520 is still in a closed state; when the duckbill planting component 520 rises, the raised portion of the cam 341 contacts the roller 3433 (is in a close state), and the raised portion of the cam 341 will lift the roller 3433, and then the extension rod 3432 of the pullback member 343 will pull the duckbill planting component 520, so that the duckbill planting component 520 is gradually opened. As the duckbill planting component 520 gradually rises, the raised portion of the cam 341 is lifted The roller 3433 is raised to its maximum height, and the duckbill planting assembly 520 is also opened to its maximum width. The seedlings in the duckbill planting assembly 520 fall into the planting pit pierced by the duckbill planting assembly 520, and then as the duckbill planting assembly 520 moves, the roller 3433 passes around the highest point of the raised portion of the cam 341, and then the roller 3433 descends, driving the duckbill planting assembly 520 to close. Since the seedlings in the pots fall close to the planting pit, no major damage will be caused to the seedlings in the pots, thereby ensuring the integrity of the seedlings in the pots and facilitating their growth.

[0055] The eccentric rod 342 drives the vertical swing assembly 510 to swing upward, thereby realizing the process of collecting seedlings of the duckbill planting assembly 520. The eccentric rod 342 drives the vertical swing assembly 510 to swing downward, and the raised portion of the cam 341 will lift the roller 3433, so that the duckbill planting assembly 520 is in an open state, thereby realizing the process of releasing seedlings of the duckbill planting assembly 520. The process runs continuously, and after releasing the seedlings, the seedlings in the pots are arranged neatly with moderate spacing, which is conducive to the growth and development of the seedlings in the pots.

[0056] In a preferred embodiment, see Figure 8 and Figure 9 The vertical swing assembly 510 includes a pair of transverse frames 511 and a pair of swing rods 512. One of the transverse frames 511 is installed on the mobile body 100, and the other transverse frame 511 is connected to the duckbill planting assembly 520. A pair of transverse rods are provided on the transverse frame 511. The swing rods 512 are rotatably connected to the transverse rods, and the pair of swing rods 512 are arranged in parallel along the vertical direction. The pair of transverse frames 511 and the pair of swing rods 512 are arranged in a parallelogram as a whole, and the swing rod 512 and the eccentric rod 342 are hinged to each other. When the eccentric rod 342 swings, the pair of swing rods 512 will rotate around the transverse frame 511 connected to the mobile body 100. Specifically, the pair of swing rods 512 rotate around a pair of transverse rods. At the same time, the transverse frame connected to the duckbill planting component 520 swings up and down, and a pair of transverse rods are provided on the transverse frame 511. The pair of swing rods 512 are rotatably provided on a pair of transverse rods. While realizing the relative rotation between the transverse frame 511 and the swing rods 512, a pair of transverse rods can prevent the swing back and forth around the swing rods 512, thereby preventing the duckbill planting component 520 from tilting.

[0057] In one possible embodiment, see Figure 10 The duckbill planting assembly 520 includes a planting cylinder 521, a duckbill tube 522 and an opener 523. The planting cylinder 521 is connected to the horizontal frame 511. The planting cylinder 521 is an open cylinder, which is convenient for the seedlings to enter the planting cylinder 521, and only one seedling can be placed in the planting cylinder 521. The duckbill tube 522 is rotatably set below the planting cylinder 521, and the duckbill tube 522 can be opened or closed. Specifically, the duckbill tube 522 is hinged on the side wall of the planting cylinder 521. By setting a rotating rod on the side wall of the planting cylinder 521, the duckbill tube 522 is rotatably set on the rotating rod, thereby realizing the rotation setting of the duckbill tube 522. The opener 523 is connected to the duckbill tube 522 for controlling the opening and closing of the duckbill tube 522.

[0058] In a preferred embodiment, see Figure 10The opener 523 includes a kneading rod 5231, a guide wheel 5232, a traction rope 5233 and a pull-back spring 5234. The kneading rod 5231 is arranged on the duckbill tube 522, and the guide wheel 5232 is arranged on the planting cylinder 521. One end of the traction rope 5233 is connected to the kneading rod 5231, and the other end passes around the guide wheel 5232 and is connected to the extension rod 3432. The pull-back spring 5234 is arranged on the duckbill tube 522. When the duckbill tube 522 is opened, the pull-back spring 5234 is in an extended state. A pair of kneading rods 5231 are provided, which are respectively provided on a pair of duckbill tubes 522 and located at the upper top of the duckbill tubes 522, so that the duckbill tubes 522 can be opened by kneading the kneading rods 5231 with each other. The guide wheel 5232 is mainly used to change the traction direction of the traction rope 5233. The pull-back spring 5234 is mainly used to pull back the opened duckbill tube 522 to close it. The specific movement process is that when the roller 3433 and one end of the extension rod 3432 are lifted, the traction rope 5233 is pulled backward, and the other end of the traction rope 5233 passes around the guide wheel 5232 and pulls the kneading rod 5231, so that the pair of kneading rods 5231 are close to each other, thereby opening the duckbill tube 522 and the return spring 5234 is in an extended state; when the roller 3433 and one end of the extension rod 3432 are lowered, since the return spring 5234 is not under force, the return spring 5234 is restored to its original state, pulling the duckbill tube 522 to close, thereby driving the kneading rod 5231 to return to its original position, and pulling the traction rope 5233 to return.

[0059] In one possible embodiment, see Figure 6 The second transmission rod mechanism 400 includes a second shaft seat 410, a second driving shaft 420, a second transmission tooth 430 and a bevel gear 440. The second shaft seat 410 is provided with a pair. The second shaft seat 410 is installed on the mobile body 100. The second driving shaft 420 is rotatably sleeved into the second shaft seat 410. The pair of second shaft seats 410 can keep the sleeved second driving shaft 420 balanced and prevent the second driving shaft 420 from swinging during rotation.

[0060] The second transmission tooth 430 is sleeved on the second driving shaft 420 and fixed to the second driving shaft 420 by a pin key or welding to prevent the second transmission tooth 430 and the second driving shaft 420 from rotating relative to each other. The second transmission tooth 430 and the first transmission tooth 350 are engaged with each other. During the rotation of the first transmission tooth 350, the second transmission tooth 430 is driven to rotate, and the second transmission tooth 430 drives the second driving shaft 420 to rotate.

[0061] The bevel gear 440 is sleeved on the second driving shaft 420 and fixed to the second driving shaft 420 by a key or welding method. It is located on the side close to the rotating assembly and is in transmission engagement with the rotating assembly. The second driving shaft 420 drives the bevel gear 440 to rotate, which in turn drives the rotating assembly to rotate.

[0062] In one possible embodiment, see Figure 1 and Figure 5 The rotating assembly includes a rotating shaft, rotating teeth and a multi-position clamping head. The rotating shaft is rotatably arranged on the mobile body 100. The rotating teeth are arranged at the bottom of the rotating shaft, and the rotating teeth and the bevel gear 440 are kneaded with each other. The rotating teeth are driven to rotate by the rotation of the bevel gear 440, and the rotating shaft is driven to rotate by the rotating teeth. The multi-position clamping head is arranged at the upper end of the rotating shaft, and a plurality of limiting holes are provided on the multi-position clamping head. The seedling pot holding assembly 620 is clamped in the limiting hole.

[0063] In a possible embodiment, the seedling pot holding assembly 620 includes a telescopic rod 621, an opening and closing seedling holding tube 622 and a limiting ring 623. One end of the telescopic rod 621 is arranged in the limiting hole. The telescopic rod 621 is extended to a preset length so that the telescopic rod 621 is extended to directly above the planting cylinder 521. The opening and closing seedling holding tube 622 is connected to the other end of the telescopic rod 621. The telescopic rod 621 adopts a sleeve telescopic method, which can be achieved by existing telescopic equipment; the limiting ring 623 is sleeved with several of the telescopic rods 621, and the limiting ring 623 is mainly used to limit the telescopic rod 621 to prevent the telescopic rod 621 from offset.

[0064] In a preferred embodiment, see Figure 5 and Figure 11The opening and closing seedling tube 622 includes a funnel tube 6221, an opening and closing mouth 6222, an inclined dial plate 6223 and a dial rod 6225. The funnel tube 6221 is vertically arranged, and the upper end of the funnel tube 6221 is open, which is convenient for the staff to place the pot seedlings in the funnel tube 6221. The bottom of the funnel tube 6221 has an inclined opening, and the opening and closing mouth 6222 is rotatably arranged at the bottom of the funnel tube 6221 for closing the inclined opening. The opening and closing mouth 6222 and the funnel tube 6221 are hinged and rotated. The inclined dial plate 6223 is tilted and arranged on the opening and closing mouth 6222 to prevent the inclined dial plate 6223 from deflecting on the opening and closing mouth 6222. The inclined dial plate 6223 is fixed on the opening and closing mouth 6222. One end of the return spring 6224 is connected to the funnel tube 6221, and the other end is connected to the opening and closing mouth 6222. The return spring 6224 mainly plays a role of pulling back and resetting. One end of the shift rod 6225 is fixedly connected to the movable seat, and the other end is in contact with the inclined dial plate 6223. The specific process is that when the lever 6225 is not in contact with the inclined dial plate 6223, under the traction of the return spring 6224, the opening and closing mouth 6222 is closed at the bottom of the funnel tube 6221, and the seedlings in the funnel tube 6221 will not fall; when the rotating shaft gradually rotates, driving the funnel tube 6221 to rotate toward the side directly above the duckbill planting component 520, the inclined dial plate 6223 contacts the lever 6225, and the funnel tube 6221 continues to rotate, and the inclined dial plate 6223 and the lever 6225 squeeze each other, which will open the opening and closing mouth. 6222 is pushed away from the bottom of the funnel tube 6221, the return spring 6224 is stretched by the force, the opening and closing mouth 6222 is gradually opened, the seedlings in the pot in the funnel tube 6221 will fall, and just enter the duckbill tube 522 that moves vertically upward, so that the seedlings fall. As the rotating shaft continues to rotate, the inclined dial plate 6223 and the dial rod 6225 are disengaged from each other (no longer in contact), and the opening and closing mouth 6222 is pulled back by the return spring 6224. The opening and closing mouth 6222 is closed at the bottom of the funnel tube 6221 and waits for the next time when the seedlings are manually released into the idle funnel tube 6221.

[0065] Specifically, a rubber pad is provided on the opening and closing mouth 6222 to prevent noise from being generated during the closing process of the opening and closing mouth 6222 and the funnel tube 6221 .
