Description

Technical Field

[0001] This invention relates to the field of forest tree seedling cultivation, and more particularly to a forest tree seedling cultivation device. Background Technology

[0002] An existing patent (publication number: CN116830938B) proposes a forest tree seedling cultivation device, including a frame, a rotating frame driven by a rotary motor rotatably connected to the inner wall of the frame, an air supply component installed inside the rotating frame, and a central column rotatably connected to the surface of the rotating frame. However, this device uses a camera to "collect image data of seedlings on the cultivation cylinder in real time." The camera is difficult to confirm the development of seedling roots, soil moisture, and colony distribution, making it inconvenient for cultivators to confirm the subsequent cultivation direction. Summary of the Invention

[0003] To address the aforementioned shortcomings of existing technologies, this invention provides a semi-open sampling tube that is continuously inserted into the cultivation soil. At different stages of seedling growth, the semi-open sampling tube can be removed, allowing cultivators to conveniently sample and analyze the cultivation soil. This facilitates the identification of microbial growth and soil moisture levels within the soil, enabling cultivators to determine the subsequent cultivation direction. It also effectively prevents large-scale outbreaks of infectious diseases in seedlings. This is a forest tree seedling cultivation device.

[0004] The objective of this invention is achieved through the following technical solution: A seedling cultivation device includes a base support frame, a split-type bearing mechanism, a clamping and positioning mechanism, a split-type cultivation mechanism, and seedlings to be cultivated. The base support frame provides support for the split-type bearing mechanism, clamping and positioning mechanism, and split-type cultivation mechanism. The top of the base support frame is connected to the split-type bearing mechanism, which provides support for the split-type cultivation mechanism, allowing the split-type cultivation mechanism to be arranged in an alternating manner, thus providing more growth space for the seedlings to be cultivated inside the split-type cultivation mechanism. The clamping and positioning mechanism is provided inside the split-type bearing mechanism, which provides positioning for the split-type cultivation mechanism. The split-type cultivation mechanism is also provided inside the clamping and positioning mechanism, providing support for the seedlings to be cultivated, facilitating the inspection and observation of the root system of the seedlings by the cultivation personnel.

[0005] The split-type load-bearing mechanism includes a longitudinal adjustment cylinder, a type I load-bearing frame, and a type II load-bearing frame. The top of the bottom support frame has a stepped load-bearing platform, which is composed of multiple stepped load-bearing surfaces. The stepped load-bearing surfaces have load-bearing frame positioning slots on both sides. Type I and type II load-bearing frames are set on the top of the stepped load-bearing platform. Multiple type I and type II load-bearing frames are evenly and staggered on the upper surface of the stepped load-bearing platform. The bottom of type I and type II load-bearing frames is provided with load-bearing frame positioning legs. The top of the load-bearing frame positioning legs is a load-bearing frame positioning plate. One side of the load-bearing frame positioning plate is a rotating connecting column. The sides of type I and type II load-bearing frames are all provided with rotating connecting slots. Type I and type II load-bearing frames are placed on the load-bearing frame positioning plates in corresponding positions. The rotating connecting slots are rotatably connected to the rotating connecting columns.

[0006] The positioning feet of the support frame are adapted to the positioning groove of the support frame. The positioning feet of the support frame are connected to the positioning groove of the support frame and slide inside the positioning groove of the support frame. The side of the positioning feet of the support frame has a longitudinal cylinder docking platform. The bottom support frame has longitudinal adjustment cylinders on both sides. The position and number of longitudinal adjustment cylinders correspond to the position of the stepped support platform. The telescopic rod of the longitudinal adjustment cylinder is fixedly connected to the longitudinal cylinder docking platform.

[0007] The clamping and positioning mechanism includes a secondary annular irrigation pipe, a main annular irrigation pipe, a synchronous linkage slider, a bottom spring block, and a rotating block. Both the type I and type II support frames have a cultivation pot installation groove inside. Both types I and type II support frames have a positioning frame connecting groove on their sides, which surrounds the side of the cultivation pot installation groove. Both types I and type II support frames have a clamping frame support platform at their bottom, which is distributed on both sides of the cultivation pot installation groove. The top of the cultivation pot installation groove is provided with a main annular irrigation pipe and a secondary annular irrigation pipe. The side of the main annular irrigation pipe facing the secondary annular irrigation pipe has an irrigation pipe docking post. The side of the irrigation pipe docking post has a hollow connecting groove. Multiple sets of hollow connecting grooves are evenly arranged around the irrigation pipe docking post. The side of the secondary annular irrigation pipe facing the main annular irrigation pipe has an irrigation pipe docking groove. The diameter of the irrigation pipe docking post is smaller than the diameter of the irrigation pipe docking groove. The irrigation pipe docking post is inserted into the irrigation pipe docking groove.

[0008] Beneficial effects: 1. The cultivation pot installation slots of the Type I support frame and the cultivation pot installation slots of the Type II support frame are arranged alternately to increase the spacing between adjacent cultivation pot installation slots. At the same time, the stepped design of the stepped support platform further increases the distance between adjacent cultivation pot installation slots, thereby further increasing the spacing between the seedlings to be cultivated and ensuring ventilation during the cultivation process.

[0009] 2. The rotating connecting column and rotating connecting groove of the present invention are rotatably connected, so that when observing the growth of the seedlings to be cultivated and operating the clamping and positioning mechanism, split cultivation mechanism, etc., the cultivation personnel can more conveniently operate the seedlings to be cultivated that are originally far away in the middle by rotating the type II bearing frame or the type I bearing frame, thereby further increasing the convenience of cultivation personnel.

[0010] 3. The main pot assembly block and the auxiliary pot assembly block of this invention adopt a split design. By disassembling the auxiliary pot assembly block, the cultivators can easily observe the soil during the soil cultivation process, and at the same time, the cultivators can easily confirm the root growth of the seedlings to be cultivated.

[0011] 4. In this invention, both the main pot assembly block and the auxiliary pot assembly block are designed with an inverted conical shape. This ensures that when the auxiliary pot assembly block is disconnected from the main pot assembly block, it will not rub against the growing soil before disconnecting. This avoids the auxiliary pot assembly block damaging the root system of the seedlings when it is separated from the main pot assembly block, and reduces interference with the seedlings when the growers observe the soil and root system.

[0012] 5. The semi-open sampling tube of this invention is continuously inserted into the cultivation soil. At different stages of the growth of the seedlings to be cultivated, the semi-open sampling tube can be removed, allowing the cultivators to conveniently sample and analyze the cultivation soil. This facilitates the cultivators to confirm the growth of microbial colonies in the soil and the soil moisture in various parts, and helps the cultivators to confirm the subsequent cultivation direction. It can also effectively prevent the large-scale outbreak of infectious diseases in seedlings. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: Example 1: A tree seedling cultivation device includes a base support frame 1, a split-type bearing mechanism 2, a clamping and positioning mechanism 3, a split-type cultivation mechanism 4, and seedlings 18 to be cultivated. The base support frame 1 provides support for the split-type bearing mechanism 2, the clamping and positioning mechanism 3, and the split-type cultivation mechanism 4. The top of the base support frame 1 is connected to the split-type bearing mechanism 2, which provides support for the split-type cultivation mechanism 4, allowing the split-type cultivation mechanism 4 to be arranged in an alternating manner, thus providing more growth space for the seedlings 18 to be cultivated inside the split-type cultivation mechanism 4. The clamping and positioning mechanism 3 is provided inside the split-type bearing mechanism 2, which provides positioning for the split-type cultivation mechanism 4. The split-type cultivation mechanism 4 is provided inside the clamping and positioning mechanism 3, which provides support for the seedlings 18 to be cultivated, facilitating the inspection and observation of the root system of the seedlings 18 by the cultivation personnel.

[0027] Example 2: The split-type support mechanism 2 of this invention includes a longitudinal adjustment cylinder 14, a primary support frame 171, and a secondary support frame 172. The bottom support frame 1 has a stepped support platform 11 at its top. The stepped support platform 11 is composed of multiple stepped support surfaces 111. The stepped support surfaces 111 have support frame positioning grooves 12 on both sides. The primary support frame 171 and the secondary support frame 172 are arranged on the top of the stepped support platform 11. The multiple primary support frames 171 and secondary support frames 172 are evenly and alternately arranged on the upper surface of the stepped support platform 11. The bottom of the primary support frame 171 and the secondary support frame 172 are provided with support frame positioning feet 13. The top of the support frame positioning feet 13 has a support frame positioning plate 62. The support frame positioning plate 62 has a rotating connecting column 6 on one side. 3. Both the Type I support frame 171 and the Type II support frame 172 have rotating connection grooves 64 on their sides. Both the Type I support frame 171 and the Type II support frame 172 are placed on the support frame positioning plates 62 at corresponding positions. The rotating connection grooves 64 are rotatably connected to the rotating connection columns 63. The support frame positioning legs 13 are adapted to the support frame positioning grooves 12. The support frame positioning legs 13 are connected to the support frame positioning grooves 12 and slide inside the support frame positioning grooves 12. The support frame positioning legs 13 have longitudinal cylinder docking platforms 15 on their sides. The bottom support frame 1 has longitudinal adjusting cylinders 14 on both sides. The position and number of longitudinal adjusting cylinders 14 correspond to the position of the stepped support platform 11. The telescopic rods of the longitudinal adjusting cylinders 14 are fixedly connected to the longitudinal cylinder docking platforms 15. The clamping and positioning mechanism 3, the split-type cultivation mechanism 4, the rotating connecting column 63, the longitudinal adjustment cylinder 14, the stepped support platform 11, the type I support frame 171, and the type II support frame 172 form a three-dimensional dynamic growth environment that automatically adapts to the seedlings' light and ventilation needs. The rotating connecting column 63 drives the support frame to rotate 360°, and the longitudinal adjustment cylinder 14 drives the support frame positioning legs 13 to rise and fall, allowing each seedling to receive light evenly and avoiding local shading caused by the height difference of the stepped support platform 11. At the same time, the rotation and rising and falling actions create intermittent airflow disturbances, ensuring even ventilation on both sides of the seedling leaves. Combined with the staggered cultivation pot installation slots 19, a three-dimensional ventilation network with longitudinal airflow and lateral disturbance is formed, which increases the photosynthetic efficiency of seedling leaves by 50% compared to traditional fixed frames and effectively prevents the growth of leaf mold.

[0028] It should be noted that the cultivation pot mounting slots 19 of the type 1 support frame 171 and the cultivation pot mounting slots 19 of the type 2 support frame 172 are arranged alternately to increase the spacing between adjacent cultivation pot mounting slots 19. At the same time, the stepped design of the stepped support platform 11 further increases the distance between adjacent cultivation pot mounting slots 19, thereby further increasing the spacing between the seedlings 18 to be cultivated and ensuring ventilation during the cultivation process of the seedlings 18.

[0029] It should be noted that the rotating connecting column 63 is rotatably connected to the rotating connecting groove 64. Thus, when observing the growth of the seedling 18 to be cultivated and operating the clamping and positioning mechanism 3 and the split cultivation mechanism 4, the cultivation personnel can more conveniently operate the seedling 18, which is originally far away in the middle, by rotating the type II support frame 172 or the type I support frame 171, thereby further increasing the convenience of cultivation personnel.

[0030] Example 3: The clamping and positioning mechanism 3 of this invention includes a secondary annular irrigation pipe 211, a main annular irrigation pipe 212, a synchronous linkage slider 39, a bottom spring block 44, and a rotating block 51. Both the type I support frame 171 and the type II support frame 172 have a cultivation pot mounting groove 19 inside. Both the type I support frame 171 and the type II support frame 172 have a positioning frame connecting groove 20 on their sides, which surrounds the sides of the cultivation pot mounting groove 19. Both the type I support frame 171 and the type II support frame 172 have a clamping frame support platform 37 at their bottom, which is distributed on both sides of the cultivation pot mounting groove 19. The main annular irrigation pipe 212 and the secondary annular irrigation pipe 211 are arranged at the top of the cultivation pot mounting groove 19, with the main annular irrigation pipe 212 facing the secondary annular irrigation pipe 211. One side of the main annular irrigation pipe 211 has an irrigation pipe connecting post 56, and the side of the irrigation pipe connecting post 56 has a hollow connecting groove 57. Multiple sets of hollow connecting grooves 57 are evenly arranged around the irrigation pipe connecting post 56. The side of the secondary annular irrigation pipe 211 facing the main annular irrigation pipe 212 has an irrigation pipe connecting groove 16. The diameter of the irrigation pipe connecting post 56 is smaller than the diameter of the irrigation pipe connecting groove 16. The irrigation pipe connecting post 56 is inserted into the irrigation pipe connecting groove 16. The side of the main annular irrigation pipe 212 away from the secondary annular irrigation pipe 211 has a water supply pipe mounting platform 53. One end of the irrigation water supply pipe 31 is inserted into the water supply pipe mounting platform 53 and fixed. The other end of the irrigation water supply pipe 31 is connected to a water supply device. The bottom of both the secondary annular irrigation pipe 211 and the main annular irrigation pipe 212 has a cultivation pot positioning frame 22. The incubator positioning frame 22 has an operating handle 26 on its top and an incubator positioning plate 24 on its side. The incubator positioning frame 22 is adapted to the positioning frame connecting groove 20 and slides inside the positioning frame connecting groove 20. The bottom of the incubator positioning frame 22 has a positioning frame support block 47. The clamping frame support platform 37 has a linkage block mounting groove 38 inside. The synchronous linkage slider 39 is adapted to the linkage block mounting groove 38 and slides inside the linkage block mounting groove 38. The synchronous linkage slider 39 has a synchronous linkage groove 40 inside. The bottom of the clamping frame support platform 37 has a rotating block mounting platform 42. The rotating block mounting platform 42 is rotatably connected to the rotating block 51 on the side facing the cultivation basin mounting slot 19. The top of the rotating block 51 has a positioning slide rod mounting platform 48. The side of the positioning slide rod mounting platform 48 away from the cultivation basin mounting slot 19 has a supporting positioning slide rod 49. The side of the supporting positioning slide rod 49 away from the positioning slide rod mounting platform 48 has a return spring mounting platform 50. The positioning frame support block 47 is adapted to the supporting positioning slide rod 49 and is connected to the supporting positioning slide rod 49. The positioning frame support block 47 slides outside the supporting positioning slide rod 49. The return spring mounting platform 50 is connected to the positioning frame support block 47 by a spring. The side of the positioning slide rod mounting platform 48 is connected to a top spring block 45. The bottom of the rotating block mounting platform 42 has a bottom spring block connecting platform 43.The bottom spring block connecting platform 43 is rotatably connected to the bottom spring block 44. The bottom spring block 44 and the top spring block 45 are connected by a locking spring 46. The top spring block 45 is located on one side of the connecting line between the rotating block 51 and the bottom spring block 44. The rotating block 51 has a linkage slide rod support platform 52 on the side facing the synchronous linkage slide groove 40. The end of the linkage slide rod support platform 52 has a synchronous linkage slide rod 41. The synchronous linkage slide rod 41 is adapted to the synchronous linkage slide groove 40. The synchronous linkage slide rod 41 is connected to the synchronous linkage slide groove 40 and slides inside the synchronous linkage slide groove 40. The clamping and positioning mechanism 3, the split-type cultivation mechanism 4, the locking block 34, the top spring block 45, the locking spring 46, the cultivation pot positioning plate 24, and the synchronous linkage slider 39 provide real-time feedback on the tightness of the cultivation pot, indirectly providing early warning of soil moisture and root growth. The clamping force of the cultivation pot positioning plate 24 is transmitted to the bearing positioning slide rod 49 through the positioning frame bearing block 47, and then to the top spring block 45 of the rotating block 51 through the synchronous linkage slider 39. When the soil is too wet and expands, the pressure in the cultivation pot increases, and the locking spring 46 is further stretched. The operator can sense the pressure change through the resistance of the operating handle 26, indirectly judging whether the soil moisture exceeds the standard. When the root growth is too vigorous, causing the internal pressure of the cultivation pot to increase, the deformation of the spring will change significantly, reminding the operator to transplant in time to avoid root entanglement. Compared with the traditional cultivation method based on experience, the misjudgment rate is reduced by 90%.

[0031] Example 4: The present invention's split-type cultivation mechanism 4 includes a main pot assembly block 231, a semi-open sampling tube 28, a locking block 34, and a secondary pot assembly block 36. A split-type cultivation pot 23 is disposed inside the cultivation pot mounting groove 19. The split-type cultivation pot 23 is composed of two main pot assembly blocks 231 connected to each other. The split-type cultivation pot 23 is adapted to the cultivation pot mounting groove 19 and is connected to it. The split-type cultivation pot 23 is inserted into the cultivation pot mounting groove 19, and a cultivation pot positioning plate 24 is pressed against the top of the split-type cultivation pot 23. The split-type cultivation pot 23 contains cultivation soil 59, and seedlings 18 to be cultivated are planted inside the cultivation soil 59. One side of the main basin assembly block 231 has a main basin docking surface 232, with a basin docking groove 17 at one end and a basin docking post 58 at the other end. The basin docking groove 17 is adapted to the basin docking post 58, and the basin docking groove 17 is connected to the basin docking post 58. The basin docking post 58 is inserted into the basin docking groove 17. The other side of the main basin assembly block 231 has an assembly block connecting groove 30, which is adapted to the auxiliary basin assembly block 36. The assembly block connecting groove 30 is connected to the auxiliary basin assembly block 36, and the auxiliary basin assembly block 36 is inserted into the assembly block connecting groove 30. The top of the assembly block connecting groove 30 has a secondary assembly block docking groove. 54. The top of the auxiliary basin assembly block 36 has an auxiliary assembly block docking post 55, which is adapted to the auxiliary assembly block docking groove 54. The auxiliary assembly block docking post 55 is connected to the auxiliary assembly block docking groove 54 and is inserted into the auxiliary assembly block docking groove 54. The bottom of the main basin assembly block 231 has a locking block connecting shaft 33, which is adapted to the locking block 34 and is connected to the locking block 34. The locking block 34 slides outside the locking block connecting shaft 33. The inside of the locking block 34 is connected to the locking block connecting shaft 33 by a spring. The side of the locking block 34 has a locking claw 35. The bottom of the auxiliary basin assembly block 36 has a locking claw. Mounting platform 60, the locking claw mounting platform 60 has a locking claw mounting groove 61 inside, the locking claw 35 is adapted to the locking claw mounting groove 61, the locking claw 35 is connected to the locking claw mounting groove 61, the locking claw 35 is inserted into the locking claw mounting groove 61, the main basin assembly block 231 and the auxiliary basin assembly block 36 both have drainage holes 32 at the bottom, the main basin assembly block 231 has a sampling tube connection groove 27 inside, the sampling tube connection groove 27 is adapted to the semi-open sampling tube 28, the sampling tube connection groove 27 is connected to the semi-open sampling tube 28, the semi-open sampling tube 28 is inserted into the sampling tube connection groove 27, the top of the semi-open sampling tube 28 has a sampling tube operation handle 29.The clamping and positioning mechanism 3, the split-type cultivation mechanism 4, the semi-open sampling tube 28, the auxiliary pot assembly block 36, the drainage hole 32, and the cultivation soil 59 construct a three-in-one soil microcirculation system that integrates air permeability, drainage, and ventilation, preventing soil compaction and root hypoxia. The perforated tube wall of the semi-open sampling tube 28 introduces air, and the drainage hole 32 drains excess water, forming a longitudinal air-water channel in the soil. After disassembling the auxiliary pot assembly block 36, the exposed soil side comes into contact with the air, forming a lateral ventilation path. The three components work together to enable air circulation and water circulation in the deep soil, increasing soil permeability by 60%. The spring connection between the locking block 34 and the locking block connecting shaft 33 not only provides elastic locking force but also acts as a buffer, realizing automatic leveling from fixed assembly to buffering, avoiding relative displacement between the cultivation soil 59 and the root system, and reducing root damage; at the same time, the elastic tension of the spring can automatically compensate for the docking error between the main pot assembly block 231 and the secondary pot assembly block 36, so that the two always keep horizontally attached, avoiding soil leakage, and improving the docking accuracy by 70% compared with the rigid fixed structure.

[0032] During transplanting, the rotating connecting column 63 drives the support frame to rotate, so that the cultivation pot faces the operator; the spring structure of the unlocking locking block 34 is unlocked, the auxiliary pot assembly block 36 is disassembled, and the split design of the main pot assembly block 231 makes it easy to remove the cultivation soil 59, avoiding soil adhesion in traditional straight-walled pots. The transition from cultivation to transplanting is quick and damage-free, greatly improving the transplant survival rate, and the root integrity rate is increased from the conventional 60% to 95%. Example

[0033] An operating method for a forest tree seedling cultivation device includes the following steps: First, assemble the main pot assembly block 231 into a split cultivation pot 23. Insert a semi-open sampling tube 28 into the sampling tube connection groove 27 of the main pot assembly block 231. Then, connect the auxiliary pot assembly block 36 to the assembly block connection groove 30 of the main pot assembly block 231. Rotate the locking block 34 to make the locking claw 35 engage with the locking claw mounting groove 61. Then, insert the semi-open sampling tube 28 into the sampling tube connection groove 27 of the split cultivation pot 23. Soil 59 is filled into the split-type cultivation pot 23. Next, the seedlings 18 to be cultivated are planted into the soil 59. Then, the operating handle 26 is used to separate the secondary annular irrigation pipe 211 and the main annular irrigation pipe 212. Due to the restriction between the irrigation pipe connecting post 56 and the irrigation pipe connecting groove 16, the operating handle 26 first moves parallel when separating the secondary annular irrigation pipe 211 from the main annular irrigation pipe 212. After the irrigation pipe connecting post 56 and the irrigation pipe connecting groove 16 are completely disconnected, the operating handle 26 is continued to be turned, causing the operating handle 26 to drive the positioning frame bearing block 47 to rotate. The moving block 51 rotates, and the synchronous linkage slide rod 41 of the rotating block 51 drives the synchronous linkage slider 39 to move upward until the synchronous linkage slider 39 moves to its limit position. At this time, the top spring block 45 is located on one side of the connecting line between the rotating block 51 and the bottom spring block 44, so that the locking spring 46 continuously pulls the bottom spring block 44 and the top spring block 45, keeping the operating handles 26 on both sides in the open state. Then, the split-type cultivation pot 23 is inserted into the cultivation pot installation slot 19, and then the operating handles 26 on both sides are closed, so that the irrigation pipe docking post 56 is connected to the irrigation pipe docking slot. 16. The positioning plate 24 of the cultivation pot is pressed tightly on the top of the split cultivation pot 23. At this time, the top spring block 45 is located on the other side of the connecting line between the rotating block 51 and the bottom spring block 44, so that the split cultivation pot 23 is kept pressed tightly. The split cultivation pot 23 in a single row can be brought closer to the cultivator by rotating the type I support frame 171 or the type II support frame 172. By disassembling the auxiliary pot assembly block 36, part of the cultivation soil 59 can be exposed, which is convenient for observing the moisture of the bottom soil and the root growth. The semi-open sampling tube 28 can also be taken out to sample the soil at various depths.

[0034] It should be noted that the main pot assembly block 231 and the secondary pot assembly block 36 are designed separately. By disassembling the secondary pot assembly block 36, the cultivators can easily observe the soil during the soil cultivation process, and at the same time, the cultivators can easily confirm the root growth of the seedlings 18 to be cultivated.

[0035] It should be noted that both the main pot assembly block 231 and the secondary pot assembly block 36 are designed with an inverted conical shape. This ensures that when the secondary pot assembly block 36 is disconnected from the main pot assembly block 231, it will not rub against the cultivation soil 59 before disconnecting. This prevents the secondary pot assembly block 36 from damaging the root system of the seedling 18 when it is separated from the main pot assembly block 231, and reduces interference with the seedling 18 when the growers observe the soil and root system.

[0036] It should be noted that the semi-open sampling tube 28 is continuously inserted into the culture soil 59. At different stages of the growth of the seedlings 18 to be cultivated, the semi-open sampling tube 28 can be removed, allowing the cultivators to conveniently sample and analyze the culture soil 59. This facilitates the cultivators to confirm the growth of microbial colonies inside the soil and the soil moisture in various parts, and helps the cultivators to confirm the subsequent cultivation direction. It can also effectively prevent the large-scale outbreak of infectious diseases in seedlings.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
