Description

Technical Field

[0001] This invention relates to the field of seedling raising equipment technology, and in particular to a seedling raising equipment for planting Torreya grandis. Background Technology

[0002] Currently, the common practice in container seedling cultivation of Torreya grandis is to use a combination of seedling cups, seedling boxes, and seedling racks. Seedling cups are used to individually hold the potting soil and Torreya grandis seeds, while seedling boxes are used to hold the cups in place. The seedling racks then allow for multi-layered arrangement to improve space utilization. However, existing Torreya grandis seedling cultivation devices still have many technical shortcomings in practical applications, making it difficult to meet the demands of large-scale, automated, and efficient seedling cultivation.

[0003] Firstly, the space is not used efficiently and is poorly adapted to large-scale cultivation. The existing seedling racks of Torreya grandis seedling devices are mostly fixed-layer structures with a single arrangement of seedling boards, which fails to achieve efficient use of space.

[0004] Secondly, the automation level is low, and the efficiency of filling and removing seedling cups is low. Existing seedling devices mostly rely on manual labor to complete operations such as loading seedling cups, filling potting soil, sowing Torreya grandis seeds, and removing seedling cups after seedling cultivation. Even if some devices are equipped with simple soil filling or sowing structures, they cannot achieve automated connection, assembly, disassembly and separation between seedling cups and seedling boards, making it difficult to meet the cultivation needs of large-scale Torreya grandis seedlings.

[0071] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0072] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0073] Example

[0074] according to Figure 1 - Figure 14 ,like Figure 1 - Figure 3 In this embodiment of the invention, a seedling raising device for planting Torreya grandis includes a seedling box 1, which has multiple layers of vertically arranged seedling trays 11 inside. It also includes several strip-shaped slots 12 arranged in a circular array on the seedling trays 11. The seedling trays 11 can be connected to an external driving device to rotate autonomously in the seedling box 1. By driving the seedling trays 11 to rotate, the position of the strip-shaped slots 12 can be adjusted. Seedling strip boxes 2 are snapped onto the inner sidewalls of the strip-shaped slots 12. Snapping strips 22 are fixed to both sides of the top of the seedling strip boxes 2. The seedling strip boxes 2 are composed of two disassembled parts spliced ​​together.

[0075] A lifting platform 3 is located on one side of the seedling tray 11. A transmission belt 31 is installed on the inner side of the lifting platform 3. Several carrier plates 32 are connected in sequence on the transmission belt 31. The upper surface of each carrier plate 32 is fixedly equipped with arc-shaped positioning plates 34 arranged in a ring array. The arc-shaped positioning plates 34 are used to insert the seedling strip box 2 and the seedling cup. The inner side of the arc-shaped positioning plates 34 is slidably connected to the cup holder 33. At the same time, the seedling tray 11 is also provided with a notch that matches the width of the part of the lifting platform 3 that extends into the seedling box 1. The transmission belt 31 can pass through the seedling tray 11 through the notch in the seedling box 1 and can also be moved upward out of the seedling box 1. The seedling box 1 and the lifting platform 3 are set separately, so that the lifting platform 3 can be moved to switch to other seedling boxes 1 for operation. Moreover, the seedling box 1 is also provided with a rotating closed door, which is closed after the lifting platform 3 is moved out of the seedling box 1.

[0076] The soil-laying box 4, the seeding box 41, the movable platform 5, and the cup-filling platform 9 are fixedly installed on the lifting platform 3 and located on the transmission path of the transmission belt 31. There are two movable platforms 5, which are distributed on both sides of the transmission belt 31.

[0077] The split structure 6, the cantilever structure 7, and the press-fit structure 8 are fixedly installed on the movable platform 5 and are synchronously raised and lowered under the control of the movable platform 5.

[0078] Both the soil-filling box 4 and the seeding box 41 are connected to a pipe 42 pointing to the carrier plate 32 on one side, and the soil and seeds are filled into the seedling cups in the seedling box 2 through the pipe 42. The pressing structure 8 is used to compact the soil in the seedling cups.

[0079] The splitting structure 6 is used to split the seedling tray 2, and the pressing structure 8 can lock the mouth of the cultivation cup to fix the position of the seedling cup when splitting the seedling tray 2;

[0080] The lifting structure 7 is used to push the cup holder 33 to move the seedling strip box 2 and the seedling cup out of the arc-shaped positioning piece 34. The lifting structure 7 can cooperate with the cup-filling platform 9 to assemble and disassemble the seedling cup on the carrier plate 32. During the automated assembly and disassembly of the seedling cup on the seedling tray 11, the lifting platform 3 drives the transmission belt 31 to rise and fall. After the arc-shaped positioning piece 34 is aligned with the strip-shaped slot 12, the seedling strip box 2 can be assembled and disassembled on the seedling tray 11. On the transmission path of the transmission belt 31, the splitting structure 6 can split and merge the seedling strip box 2, and the lifting structure 7 and the cup holder 33 can facilitate the splitting and merging process. The system can transfer seedling cups between the arc-shaped positioning plate 34 and the seedling tray 2, and can also replace seedling cups in the arc-shaped positioning plate 34 by cooperating with the cup-filling platform 9. It can automatically and continuously replace seedling cups in the seedling tray 2 on the seedling tray 11. That is, after filling the new empty cup with cultivation soil and seeds and compacting it with the pressing structure 8, it is placed on the seedling tray 11 through the seedling tray 2. After the seedlings are finished, the seedling cups are removed from the seedling tray 11 and the seedling tray 2. It can continuously and cyclically replace the seedlings. During the batch cultivation of Torreya grandis, the various processes are smoothly connected and highly automated.

[0081] like Figure 6 In this system, a water-passing ring 1101 is provided on the seedling tray 11, and a cup-carrying cavity 21 is provided inside the seedling box 2. The cup-carrying cavities 21 are interconnected. One end of the seedling box 2 is fixedly connected to an insert 25, and one end of the insert 25 is inserted into the water-passing ring 1101. The water-passing ring 1101 belongs to the existing irrigation system in the seedling box 1. With the setting of the insert 25, when the seedling box 2 is snapped onto the seedling tray 11, the seedling box 2 is simultaneously inserted into the water-passing ring 1101 through the insert 25, so that the internal cavity of the seedling box 2 is connected to the irrigation system. The cultivation cups are irrigated through the cup-carrying cavity 21, and the breathing hole on the cultivation cup can communicate with the outside air through the cup-carrying cavity 21.

[0082] like Figure 5 In the above, the splicing parts of the seedling strip box 2 are respectively provided with a connecting clip 23 and a connecting plug 24. The connecting clip 23 and the connecting plug 24 are respectively provided on the two split parts of the seedling strip box 2. The connecting plug 24 is movably inserted into the connecting clip 23. After the split parts of the seedling strip box 2 are combined, the combined state of the seedling strip box 2 is fixed by the mutual connection of the connecting clip 23 and the connecting plug 24. And the two split parts are easy to separate when the seedling strip box 2 is disassembled.

[0083] like Figure 5 and Figure 7In this design, an inner top plate 3301 is slidably connected to the middle of the cup holder 33. A guide slide post is installed at the bottom end of the inner top plate 3301, and the guide slide post passes through and slidably connects to the bottom of the cup holder 33. Slide tracks 3302 are provided at both ends of the cup holder 33. Limiting grooves 3304 are slidably connected to the inner sidewalls of the slide tracks 3302. A lifting spring 3305 is fixedly connected between the bottom of the inner top plate 3301 and the inner bottom wall of the cup holder 33. Movable pressure rods 3303 are hinged to both sides of the inner top plate 3301. The other end of each movable pressure rod 3303, away from the inner top plate 3301, is slidably connected within the limiting groove 3304, lifting... Under its own elasticity, the spring 3305 can actively lift the inner top plate 3301 to slide upward in the middle of the cup holder 33. While the inner top plate 3301 slides upward, it drives one end of the movable pressure rod 3303 to rise. The other end of the movable pressure rod 3303 slides in the limiting slide groove 3304, so that the height of the inner top plate 3301 is higher than the height of the cup holder 33. When the cultivation cup is empty, it can actively lift the height of the cultivation cup in the arc-shaped positioning piece 34. The diameter of the inner top plate 3301 is smaller than the diameter of the cultivation cup, so that the empty cultivation cup is on the cup holder 33, and the outer side of the bottom of the cultivation cup is suspended, which makes it convenient to clamp the cultivation cup when the seedling box 2 is combined.

[0084] like Figure 6 and Figure 10 In this context, the active platform 5 includes: a mounting plate 51 fixedly installed on the lifting platform 3;

[0085] A movable frame 52 is liftably mounted on a mounting plate 51. A movable limiting rod 54 is fixedly connected to the bottom end of the movable frame 52. A seat 53 is fixedly connected to the upper surface of the mounting plate 51. The bottom end of the movable limiting rod 54 passes through the side wall of the slidingly connected seat 53.

[0086] A movable cylinder 55 is fixedly installed on the mounting plate 51. The output end of the movable cylinder 55 is fixedly connected to the movable frame 52. The movable limit rod 54 is slidably connected to the seat cylinder 53, which can limit the lifting path of the movable frame 52 and prevent the movable frame 52 from shaking when it is raised or lowered. At the same time, after the split structure 6, the lifting support structure 7 and the pressing structure 8 are all installed on the movable frame 52, the movable frame 52 can control the split structure 6, the lifting support structure 7 and the pressing structure 8 to lift and lower synchronously.

[0087] like Figure 6 , Figure 8 - Figure 11In the process, the split structure 6 includes two docking plates 61 located on both sides above the transmission belt 31. Two translational slide rods 64 are fixedly connected to one side of each docking plate 61, and a split telescopic rod 65 is fixedly connected to one side of each docking plate 61. Both the translational slide rods 64 and the split telescopic rods 65 are fixedly installed on the movable platform 5. The upper surface of each docking plate 61 has a docking groove 62 for engaging the engaging strip 22. Both sides of the strip groove 12 have engaging slide grooves 1201 for engaging the engaging strip 22. The top of the seedling box 2 has several protrusions for positioning on both sides. The top of both sides of the strip groove 12 has cultivation positioning grooves 13 adapted to the protrusions. The upper surface of the docking plate 61 has translational slide rods 64 adapted to the protrusions. When the movable platform 5 drives the split structure 6 to descend, the transmission belt 31 and the arc-shaped positioning plate 3... 4. After the seedling tray 2 is transferred between the two docking plates 61, the docking plates 61 and the translation slide bar 64 are moved synchronously by activating the split telescopic rod 65. The translation slide bar 64 slides on the movable platform 5 to support the movement of the docking plates 61. After the docking plates 61 are located on both sides of the seedling tray 2, the docking slot 62 is located directly below the snap-fit ​​strip 22. At this time, the docking plates 61 are moved upward by the movable platform 5, and the seedling tray 2 can be snapped onto the docking plates 61 by the snap-fit ​​strip 22. The protruding part is snapped into the split positioning groove 63 to fix the position of the seedling tray 2 on the docking plates 61. Continue to move upward, and the bottom of the seedling tray 2 can be disengaged from the arc-shaped positioning piece 34 by the docking plates 61. Then activate the split telescopic rod 65 to retract, and the two split parts of the seedling tray 2 can be separated by the docking plates 61. The reverse operation can be used to reassemble the two split parts of the seedling tray 2.

[0088] like Figure 6 , Figure 7 , Figure 9 - Figure 11 In the process, the lifting structure 7 includes: a lifting plate 71 fixed to the movable platform 5, one end of the lifting plate 71 extending to the bottom of the cup-filling platform 9;

[0089] The cup holder 33 is integrally formed with two lifting ears 72 at both ends. The lifting plate 71 is located below the lifting ears 72. When the movable platform 5 is raised, the lifting plate 71 lifts the lifting ears 72, thereby moving the cup holder 33 to the top of the arc-shaped positioning plate 34. When the movable platform 5 raises the lifting structure 7, the lifting plate 71 lifts the lifting ears 72, causing the cup holder 33 to slide in the arc-shaped positioning plate 34. This allows the seedling cups and seedling strip boxes 2 in the arc-shaped positioning plate 34 to be lifted upwards and out of the arc-shaped positioning plate 34. At this time, the seedling strip box 2 can be disassembled in conjunction with the splitting structure 6. The operation can also be combined with the split structure 6 to splice and operate the seedling tray 2, so that the empty cup on the cup holder 33 can be clamped into the seedling tray 2. The part of the lifting plate 71 extending to the bottom of the cup filling platform 9 can be used with the cup filling platform 9 to push the seedling cup in the arc-shaped positioning piece 34 away, remove the cup holder 33 and the arc-shaped positioning piece 34. When the lifting plate 71 descends, the lifting ear 72 descends with the lifting plate 71, thereby driving the cup holder 33 to fall into the arc-shaped positioning piece 34, so that the empty seedling cup newly placed on the cup holder 33 through the cup filling platform 9 can be placed into the arc-shaped positioning piece 34.

[0090] like Figure 5 and Figure 7 In this configuration, the bottom of each of the lifting ears 72 is fixedly connected to a limiting hook 73. Both sides of the transmission belt 31 are provided with annular limiting plates 74, which are all mounted on the lifting platform 3. The hook portions of the limiting hooks 73 are located inside the annular limiting plates 74. The bottom of the lifting ear 72 is slidably connected to the outer wall of the annular limiting plate 74. When the lifting plate 71 drives the cup holder 33 to rise within the arc-shaped positioning piece 34 via the lifting ear 72, it simultaneously drives the limiting hooks 73 to rise. The hook part of hook 73 is located inside the annular limiting plate 74, which can prevent the lifting ear 72 from being raised too high, thereby limiting the rising height of cup holder 33 in arc-shaped positioning plate 34. In addition, the setting of the annular limiting plate 74 can also share the load of the carrying plate 32 when the transmission belt 31 lifts the seedling box 2 through the carrier plate 32, and when the arc-shaped positioning plate 34 loads the seedling cup and seedling box 2. The bottom of the lifting ear 72 abuts against the annular limiting plate 74, which can also share the load of the carrying plate 32 and prevent the transmission belt 31 from deforming under the load.

[0091] like Figure 8 - Figure 12 In the process, the pressing structure 8 includes: an L-shaped bracket 81 fixedly installed on the movable platform 5, the part of the pipe 42 fixed on the L-shaped bracket 81 being a flexible hose, and the part of the pipe 42 fixed on the L-shaped bracket 81 being a rigid pipe, which can maintain alignment with the seedling cups in the seedling tray 2. Thus, during the process of the pressing structure 8 rising and falling with the movable platform 5, the pipe 42 can deform to cope with the height change of the pipe 42 installed at one end of the pressing structure 8, and maintain stable communication between the soil box 4 and the seed box 41 and the pipe 42.

[0092] Several guide grooves 85 are formed on the L-shaped bracket 81;

[0093] The guide rod 84 is slidably connected inside the guide groove 85;

[0094] A bent pressure rod 83 is fixedly connected to one end of the guide slide rod 84 near the transmission belt 31. The upper part of the bent pressure rod 83 is set as a vertical section and the lower part is set as an inclined section. The vertical section of the bent pressure rod 83, that is, the top, is fixedly connected to the guide slide rod 84. The outer wall of the bent pressure rod 83 is slidably connected to the end of the horizontal section of the L-shaped bracket 81.

[0095] The crescent-shaped pressure plate 82 is fixed to the bottom of the bent pressure rod 83. The bottom of the crescent-shaped pressure plate 82 is provided with a stepped groove. That is, the protruding part of the bottom of the crescent-shaped pressure plate 82 is adapted to the inner diameter of the top of the seedling cup. This allows the bottom protrusion of the crescent-shaped pressure plate 82 to engage with the mouth of the seedling cup when it moves down. When the seedling cup is filled with potting soil, the potting soil is compacted into the cup. The outer edge of the stepped groove is larger than the diameter of the mouth of the seedling cup. It can press the seedling strip box 2 on the upper surface of the seedling strip box 2 when the seedling strip box 2 is closed, avoiding excessive downward pressure of the crescent-shaped pressure plate 82 from damaging the soil compaction requirements in the seedling cup.

[0096] A synchronous pressure plate 88 is slidably sleeved on the guide slide rod 84, and the synchronous pressure plate 88 is located inside the L-shaped bracket 81;

[0097] A press-fit telescopic rod 89 is fixedly connected to an L-shaped bracket 81, and the output end of the press-fit telescopic rod 89 is fixedly connected to a synchronous pressure plate 88;

[0098] A retraction spring 87 and a pad 86 are slidably fitted onto the guide slide rod 84. Both the pad 86 and the retraction spring 87 are located on the outside of the L-shaped bracket 81. The two ends of the retraction spring 87 are fixedly connected to the end of the guide slide rod 84 away from the bent pressure rod 83 and the side of the pad 86 away from the L-shaped bracket 81, respectively. The pad 86 is fixedly connected to the synchronous pressure plate 88 via a connecting block. Both the synchronous pressure plate 88 and the pad 86 are slidably connected to the outer wall of the L-shaped bracket 81. The pad 86 and the synchronous pressure plate 88 are fixedly connected to each other and slide close to the outer wall of the L-shaped bracket 81. This not only restricts the vertical sliding trajectory of the guide slide rod 84 through the guide groove 85, but also allows the synchronous pressure plate 88 to slide through the pad. 86 is slidably connected to the outer wall of the L-shaped bracket 81, restricting the vertical sliding trajectory of the synchronous pressure plate 88, keeping the synchronous pressure plate 88 horizontal when sliding vertically, thereby restricting the guide slide rod 84 to remain horizontal, thus keeping the crescent pressure plate 82 horizontal and preventing the crescent pressure plate 82 from tilting upwards. When the output end of the press-fit telescopic rod 89 extends downwards, it drives the synchronous pressure plate 88 to move downwards, and the synchronous pressure plate 88 drives multiple guide slide rods 84 to move downwards synchronously. The guide slide rods 84 maintain stable downward sliding in the guide groove 85, while the retraction spring 87, under its own elasticity, pulls the guide slide rods 84 to keep one side of the bent pressure rod 83 in contact with the end of the horizontal section of the L-shaped bracket 81, so that the bent pressure rod 83... 3. When the horizontal section of the inclined end attached to the L-shaped bracket 81 moves downward, the bottom end of the crescent-shaped pressure plate 82 moves obliquely downward, allowing the crescent-shaped pressure plates 82 on both sides of the transmission belt 31 to move closer together. After the two crescent-shaped pressure plates 82 reach a preset distance, the bending pressure rod 83 continues to move downward, causing the part of the bending pressure rod 83 attached to the end of the L-shaped bracket 81 to become a vertical part. Thus, during the continued downward movement of the bending pressure rod 83, the bending pressure rod 83 no longer changes in the lateral direction, keeping the crescent-shaped pressure plate 82 moving vertically downward. It can use the stepped groove to press into the inside of the seedling cup mouth, compacting the soil in the seedling cup. In addition, the crescent-shaped pressure plate 82 can use the stepped groove to engage with the mouth of the seedling cup. When the splitting structure 6 separates the seedling tray 2, the position of the seedling cup can be fixed so that after the seedling tray 2 and the seedling cup are separated smoothly, the seedling cup remains in its original position. When the movable platform 5 controls the splitting structure 6 and the lifting structure 7 to move down, the pressing structure 8 also moves down, maintaining the snap-fit ​​state with the seedling cup, so that the seedling cup can accurately enter the arc-shaped positioning piece 34. In addition, during the process of the docking plate 61 moving up and snapping with the snap-fit ​​strip 22 on the seedling tray 2, the outer edge of the crescent pressing plate 82 presses the seedling tray 2 in the combined state, so that the snap-fit ​​strip 22 on the seedling tray 2 is completely snapped in the docking slot 62, ensuring the snap-fit ​​accuracy between the seedling tray 2 and the docking plate 61.

[0099] like Figure 13 and Figure 14In the process, the cup-filling platform 9 includes: a cup-filling frame 91 fixedly connected to the outer wall of the lifting platform 3;

[0100] A wave-shaped push plate 92 is slidably connected to the inner side wall of the cup-filling frame 91. A push-pull slide rod 93 is fixedly connected to the outer side wall of the wave-shaped push plate 92. The push-pull slide rod 93 passes through the side wall of the cup-filling frame 91.

[0101] A removable telescopic rod 94 is fixedly installed on the cup frame 91, and the output end of the removable telescopic rod 94 is fixedly connected to the wave push plate 92.

[0102] A bent loading and unloading plate 95 hinged to one end of the cup frame 91;

[0103] A bent telescopic rod 96 is hinged between the cup-filling frame 91 and the bent loading and unloading plate 95;

[0104] The inner bottom wall of the cup-filling frame 91 has a notch that matches the arc-shaped positioning piece 34, and the inner bottom of the cup-filling frame 91 is flush with the top of the arc-shaped positioning piece 34.

[0105] The operational process of mounting, unmounting, and filling the seedling cups with soil in this embodiment is suitable for the needs of large-scale cultivation of Torreya grandis.

[0106] During the process of loading seedling cups, empty cups are placed in batches into the bent loading and unloading plate 95. The movable frame 52 is lifted by the movable cylinder 55, which drives the lifting plate 71 to move upward. The lifting plate 71 drives the cup holder 33 to move upward in the arc-shaped positioning piece 34 by pushing the lifting ear 72, so that the inner top plate 3301 is flush with the inner bottom wall of the cup loading frame 91. The concave part of the wave push plate 92 corresponds to the top of the arc-shaped positioning piece 34 and is used to position the empty cup. The bent loading and unloading plate 95 reverses upward to drive the empty cup to slide automatically into the concave part of the wave push plate 92, that is, above the inner top plate 3301 and the cup holder 33. The lifting plate 71 is controlled to move downward until the lifting ear 72 separates, so that the cup holder 33 moves downward and the empty cup enters the inner side of the arc-shaped positioning piece 34 arranged in a ring on the carrier plate 32.

[0107] Then, the seedling cups are filled with soil, sown, and compacted. Following the transmission path of the drive belt 31, the carrier plate 32 and empty cups are transported to the movable frame 52. The movable frame 52 is controlled to move the lifting plate 71 upwards, using the cup holder 33 to lift the empty cups upwards. Then, the split telescopic rods 65 on both sides of the empty cups are activated, causing the separate seedling strip boxes 2 to merge and converge via the docking plate 61, clamping the empty cups into the carrier cup cavity 21. It is worth noting that... Figure 5 and Figure 7In the case of an empty seedling cup, the inner top plate 3301 is pushed higher than the cup holder 33 by the lifting spring 3305. Furthermore, the movable pressure rod 3303 tilts along with the inner top plate 3301 in the slide rail 3302. At this time, the bottom of the empty cup is higher than the cup holder 33 and higher than the bottom wall of the cup-carrying cavity 21. During the merging action of the connecting plate 61 and the separate seedling strip boxes 2, the outer side of the empty cup, which is suspended in the air, first enters the cup-carrying cavity 21, while the bottom of the seedling strip box 2 then contacts the movable pressure rod 3303. Due to the merging action of the seedling strip box 2... During the process, the horizontal height remains constant, and the inner top plate 3301 slides vertically on the cup holder 33 due to the limitation of the guide slide column. Therefore, the bottom of the seedling tray 2 slides against the inclined movable pressure rod 3303, causing the bottom end of the movable pressure rod 3303 to slide within the limiting slide groove 3304. The top end of the movable pressure rod 3303 moves downward, thereby driving the inner top plate 3301 to gradually move downward. The empty cup first enters the cup-carrying cavity 21 and then gradually separates from the inner top plate 3301. This can prevent the empty cup from being accidentally clamped when the seedling tray 2 is closed, while ensuring that the empty cup is smoothly clamped on the carrier of the seedling tray 2. Inside the cup cavity 21, after the seedling trays 2 are combined, the soil-filling box 4 and the seeding box 41 respectively deliver potting soil and Torreya grandis seeds into the empty cup through the pipe 42. After delivery, the pressing telescopic rod 89 is activated, causing the synchronous pressing plate 88 to move downward. The synchronous pressing plate 88 drives several guide sliding rods 84 and bending pressing rods 83 to move downward synchronously. During the downward movement of the bending pressing rod 83, its inclined surface first contacts the end of the horizontal section of the L-shaped bracket 81 and slides downward. As the height of the bending pressing rod 83 gradually decreases, the bottom end of the bending pressing rod 83 drives the crescent pressing plate 82 to move downward into the cup cavity. The bending pressure rod 83 moves gradually from directly above the seedling cup and the cup-carrying cavity 21. After reaching directly above the seedling cup and the cup-carrying cavity 21, the bending pressure rod 83 continues to move downward. At this time, the bending pressure rod 83 switches to sliding with the vertical section against the horizontal section end of the L-shaped bracket 81. At this time, the two crescent-shaped pressure plates 82 directly above the seedling cup are joined together and move downward synchronously to compact the cultivation soil in the seedling cup. Since the crescent-shaped pressure plate 82 is provided with stepped grooves, when it is pressed down, the bottom protruding part of the crescent-shaped pressure plate 82 is first inserted into the seedling cup body to compact the cultivation soil until the outer edge of the crescent-shaped pressure plate 82 abuts against the upper surface of the cup-carrying cavity 21.

[0108] After compaction, the combined seedling tray 2, along with the seedling cups, is assembled onto the seedling tray 11. First, the seedling tray 2 is transferred to the arc-shaped positioning plate 34 on the transmission belt 31. The movable cylinder 55 is activated, which drives the docking plate 61 and the lifting plate 71 to move down synchronously through the movable frame 52, so that the cup holder 33 and the seedling tray 2 both enter the inner side of the arc-shaped positioning plate 34. Then, the docking plate 61 continues to move down, causing the docking groove 62 and the split positioning groove 63 to separate from the locking strip 22, so that the seedling tray 2 is detached from the docking plate 61 and transferred into the arc-shaped positioning plate 34. Then, the transmission belt 31 continues to drive, which can be achieved through the lifting platform. 3. The height of the transmission belt 31 is controlled to control the height of the seedling tray 2 relative to the seedling tray 11 in the strip groove 12. The height of the top of the seedling tray 2 is higher than the height of the seedling tray 11. After entering the seedling tray 11 through the strip groove 12 and entering the preset position in the strip groove 12, the lifting platform 3 drives the transmission belt 31 to descend, so that the seedling tray 2 falls into the strip groove 12. The snap-fit ​​strip 22 is inserted into the snap-fit ​​slide 1201. The upper protrusion of the seedling tray 2 enters the cultivation positioning groove 13. The insert 25 is inserted into the water ring 1101 until the arc-shaped positioning piece 34 separates from the seedling tray 2.

[0109] Remove the culture cups from the other cultured seedling strip boxes 2 on the seedling tray 11. Then, control the seedling tray 11 to rotate at a preset angle using the drive device built into the seedling box 1, so that another strip slot 12 is placed directly above the transmission belt 31. Align the arc-shaped positioning piece 34 with the seedling strip box 2 in this strip slot 12. Control the transmission belt 31 and the arc-shaped positioning piece 34 to raise the height through the lifting platform 3, so that the seedling strip box 2 is inserted into the inner side of the arc-shaped positioning piece 34. Then, continue to raise the height of the seedling strip box 2 through the arc-shaped positioning piece 34, so that the pick ear 72 on the cup holder 33 abuts against the outer wall of the annular limiting plate 74, causing the seedling strip box 2 to separate from the locking slide 1201 and the culture positioning groove 13. Drive the transmission belt 31 to reverse the transmission of the seedling strip box 2, and remove the seedling strip box 2 from the seedling tray 11.

[0110] The seedling cups containing the Torreya grandis seedlings are transferred through the seedling tray 2 to the docking plates 61 on both sides of the conveyor belt 31 for cup removal. At this time, the docking plates 61 are located below the locking strip 22, and the lifting plate 71 is located below the lifting ear 72. The movable frame 52 moves the docking plates 61 and the lifting plate 71 upward. The docking slot 62 on the docking plates 61 engages with the locking strip 22, and the split positioning slot 63 engages with the upper outer protrusion of the seedling tray 2. At the same time, the lifting plate 71 contacts the bottom of the lifting ear 72. Then the movable frame 52 continues to move upward, and the docking plates 61 and the cup holder 33 simultaneously move the seedling tray 2 out of the arc-shaped positioning piece 3. 4. Then, activate the pressing structure 8, so that the bottom of the crescent-shaped pressing plate 82 is engaged with the top of the seedling cup. At the same time, the outer edge of the crescent-shaped pressing plate 82 presses down on the seedling tray 2 on the connecting plate 61, ensuring that both sides of the seedling tray 2 are stably engaged with the connecting plate 61. This also ensures that there is no gap between the bottom of the seedling tray 2 and the cup holder 33, and that the bottom of the crescent-shaped pressing plate 82, engaged with the top of the seedling cup, can fix the position of the seedling cup. Then, activate the split telescopic rod 65 to control the two connecting plates 61 to separate from each other. By pulling the two sides of the seedling tray 2 through the connecting plates 61, the two disassembled parts of the seedling tray 2 gradually separate. During the separation of the seedling box 2, it is worth noting that the seedling cup falls onto the cup holder 33. Because the diameter of the inner top plate 3301 is smaller than that of the seedling cup, the position of the seedling cup is fixed by the crescent-shaped pressure plate 82 during the separation of the seedling box 2. Furthermore, under the action of the lifting spring 3305, the inner top plate 3301 first contacts the bottom of the seedling cup. After the bottom of the seedling cup separates from the bottom of the seedling box 2, due to the thickness of the bottom of the seedling box 2, there is a certain height difference between the inner top plate 3301 and the cup holder 33. The inner top plate 3301 contacts the bottom of the seedling cup first. When the seedling cup falls, the weight of the seedling cup presses down on the inner top plate 3301 towards the cup holder. The dynamic pressure rod 3303 falls, and the inner top plate 3301 slides downward in the cup holder 33 until it is hidden in the cup holder 33. During this process, the lifting spring 3305 plays a certain role in buffering the bottom of the seedling cup through the inner top plate 3301, reducing the impact when the seedling cup falls to the cup holder 33, and more importantly, reducing the displacement of the seedling cup. Then, the crescent pressure plate 82 is controlled to reset, and the lifting plate 71 uses the cup holder 33 to lift the seedling cup through the lifting ear 72. Then, the lifting plate 71 is driven to move downward through the movable frame 52. Under the action of gravity, the seedling cup and the cup holder 33 fall to the inside of the arc-shaped positioning plate 34, transferring the individual seedling cups to the carrier plate 32.

[0111] After transferring the seedling cups to the carrier plate 32, the control belt 31 continues to drive the removed seedling cups to the cup-filling frame 91. After transferring the separated seedling cups out of the carrier plate 32, the movable frame 52 needs to be controlled again to drive the lifting plate 71 to move upward. After the cup holder 33 is raised to the same height as the inner bottom wall of the cup-filling frame 91 through the lifting lug 72, the disassembly and assembly telescopic rod 94 is activated to push the wave push plate 92, so that the concave part of the wave push plate 92 is gradually inserted into the outside of the seedling cup. Then, the movement continues to push the seedling cup away from the cup holder 33 and place it on the bending loading and unloading plate 95. The bending telescopic rod 96 is activated to drive the bending loading and unloading plate 95 to rotate, so that the bending loading and unloading plate 95 is tilted, and the seedling cup can slide to the other side of the bending loading and unloading plate 95.

[0112] It can continuously fill the seedling cups on the seedling tray 11, perform soil filling, sowing, compaction and tray filling operations, and then remove the cups and remove them. It is a continuous automated cycle operation with a high degree of automation and is suitable for mass seedling production of Torreya grandis.
