Description

Technical Field

[0001] The present invention relates to the field of seedling cultivation, and specifically relates to a forestry seedling cultivation device. Background Art

[0002] A forestry seedling cultivation device is a professional device for cultivating forestry seedlings. By setting a suitable temperature environment in the cultivation device, it can effectively promote the germination of its seeds and the growth of seedlings, and is a facility that provides suitable environmental conditions for the germination of forest tree seeds and the growth of seedlings.

[0003] Traditional detachable planting beds are mostly assembled with connectors such as bolts and nuts during production, and cannot be disassembled and assembled by users according to the situation. In addition, if damaged during the disassembly process, it will affect reuse; during the seedling cultivation process, this drawback leads to the situation that when seedlings need to be transferred to a cultivation site or the seedling cultivation substrate needs to be replaced, the staff cannot quickly disassemble the equipment, and it will also damage the growing root system of the seedlings due to improper disassembly and assembly, reducing the survival rate of the seedlings. When fixed horizontally, either there are insufficient fixing points resulting in poor stability and easy loosening when subjected to external forces (such as handling collisions, etc.); or a complex fixing structure is adopted, increasing the equipment cost and installation difficulty; when arranged vertically, traditional planting beds usually have difficulty in balancing stability and convenience. Some planting beds using a single fixing method cannot effectively resist the influence of gravity and are prone to problems such as separation and tilting of the upper and lower components; while planting beds with multiple complex fixing structures increase the difficulty of disassembly and are not conducive to flexible use. In actual seedling cultivation scenarios, the difficulty of disassembling the seedling bed makes it impossible for the staff to adjust the space layout in a timely manner according to the growth of the seedlings, restricting the healthy growth of the seedlings. At the same time, the fixing and disassembly methods of traditional planting beds are often relatively single, difficult to adapt to different scenarios and requirements, restricting the application range of the equipment, and thus unable to meet the different needs of different seedlings by adjusting the planting bed structure, reducing the professionalism of seedling cultivation.

[0004] The water supply system of traditional planting beds is mostly of an integral design, making it difficult to flexibly increase or decrease modules according to actual needs. When it is necessary to expand or reduce the planting scale, either a complex pipeline system needs to be re-laid, or only simple splicing can be carried out on the original system, resulting in uneven water flow distribution and affecting the irrigation effect. During the seedling cultivation process, this water supply system cannot accurately control the water supply volume of seedlings in different areas, making it difficult to achieve differential water supply, and will cause problems such as withering of some seedlings due to water shortage.

[0005] When traditional detachable planting beds are used in horizontal and vertical combinations, they usually adopt the method of connecting external independent water pipes, resulting in messy water pipes, which not only affects the operation space but also easily leaks due to bending and pulling; at the same time, the sealing of the water supply system of traditional planting beds relies on conventional seals such as rubber sealing rings and flange plates. After long-term use, the seals are prone to aging and wear, resulting in water leakage and affecting the daily seedling cultivation management operations.

[0006] Therefore, it is necessary to provide a forestry seedling cultivation device aimed at solving the above problems. Summary of the Invention

[0007] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a forestry seedling cultivation device.

[0008] To achieve the above purpose, the present invention provides the following technical solution: A forestry seedling cultivation device includes a seedling raising bed and a sealing cover. The sealing cover is slidably connected to the outer wall of the seedling raising bed, and three sealing covers are linearly arranged. A connection component is arranged on the outer side of the sealing cover;

[0009] The connection component includes a first rectangular block fixedly connected to the outer wall of one of the sealing covers, and second rectangular blocks are fixedly connected to the outer walls of the remaining two sealing covers. Limiting sliding grooves are opened on the first rectangular block, the second rectangular blocks, and the top of the sealing cover. A first limiting plate is slidably connected to the inside of each limiting sliding groove, and first trapezoidal limiting blocks are fixedly connected to the limiting sliding grooves of the second rectangular blocks and the sealing covers.

[0010] Preferably, the connection component further includes a second limiting plate symmetrically slidably connected to the bottoms of the second rectangular blocks and the remaining two sealing covers, and second trapezoidal limiting blocks are symmetrically fixedly connected to the tops of the two second rectangular blocks and the remaining two sealing covers.

[0011] Preferably, a communication component is arranged inside the first rectangular block and the second rectangular blocks. The communication component includes a three-way pipe arranged inside the first rectangular block, four-way pipes are arranged inside the two second rectangular blocks, a water inlet pipe is arranged at one end of the three-way pipe, sealing blocks are fixedly connected to the remaining two ends of the three-way pipe, and connecting pipes are fixedly connected to the two ends of the four-way pipe far from the sealing blocks.

[0012] Preferably, the communication component further includes a fan-shaped groove block fixedly connected to the inner wall of the sealing block. Three trigger holes are annularly distributed inside the fan-shaped groove block. A first return spring is fixedly connected to the center of the fan-shaped groove block, and a sealing disc is fixedly connected to the end of the first return spring far from the fan-shaped groove block.

[0013] Preferably, the connecting component further includes a water-passing ring which is fixedly connected to the inner wall of the connecting pipe. The outer wall of the water-passing ring is fixedly connected with a second return spring, and the end of the second return spring away from the water-passing ring is fixedly connected with a sealing plug. A matching block is fixedly connected to the inner wall of the connecting pipe, and three abutting rods are fixedly connected to the outer wall of the matching block in an annular distribution. Two groups of water pipes are arranged vertically inside both the three-way pipe and the four-way pipe, and three water pipes form a group, and the water pipes penetrate through the inside of the sealing cover.

[0014] Preferably, there is an interference fit between the first limiting plate and the limiting sliding groove, and there is an interference fit between the second limiting plate and both the second rectangular block and the remaining two sealing covers.

[0015] Preferably, both the first limiting plate and the first trapezoidal limiting block are arranged horizontally, and the first trapezoidal limiting block is located on the movement track of the first limiting plate. The second limiting plate and the second trapezoidal limiting block are arranged vertically, and the second trapezoidal limiting block is located on the movement track of the second limiting plate.

[0016] Preferably, the three-way pipe and the four-way pipe are communicated with each other.

[0017] Preferably, the connecting pipe is sleeved on the outside of the sealing block, and the abutting rod is slidably connected to the inside of the triggering hole.

[0018] Preferably, the sector groove block and the sealing disc cooperate with each other, and the sealing plug and the matching block cooperate with each other.

[0019] A forestry seedling cultivation device provided by the present invention, compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] Through the cooperation of structures such as the connecting pipe, the abutting rod, and the sealing disc, whether arranged horizontally or vertically, the internal water source can be automatically circulated, realizing the automatic switching of the water supply system under horizontal and vertical arrangements, without additional pipe adjustment or complex operations, improving the applicability of the equipment, ensuring stable water supply during the seedling cultivation process, providing a continuous and suitable water environment for the growth of seedlings, and avoiding poor growth of seedlings caused by insufficient or unstable water supply.

[0021] When the connecting pipe is inserted into the sealing block, the abutting rod pushes the sealing disc to move, and the unsealed sealing disc is closely attached to the sector groove block under the action of the first return spring, realizing automatic sealing, preventing water leakage, avoiding the leakage problem caused by the aging and wear of the sealing parts. Whether arranged horizontally or vertically, the sealing performance of the water supply system can be ensured, reducing water resource waste, and avoiding the influence of water seepage in the seedling bed on seedling cultivation.

[0022] When arranged horizontally or vertically, each rectangular block, sealing cover, and seedling bed form independent and connectable units. When adding new modules, only fix and connect them according to the same structural principle to automatically access the water supply system, ensure the smooth flow of water source, improve the expandability and flexibility of the equipment, and be able to quickly adjust the water supply system according to different seedling cultivation scales, improve irrigation efficiency, and enable the seedling raising work to flexibly expand or shrink according to the seedling breeding plan, and timely meet the needs of seedlings for growth space and water at different stages.

[0023] Through the cooperation of the first limiting plate and the first trapezoidal limiting block, and the second limiting plate and the second trapezoidal limiting block, disassembly and fixation can be achieved through simple rotation and pulling operations without the need for additional tools. The process is simple to operate, shortening the disassembly and assembly time, reducing the risk of component damage at the same time, and improving the reuse rate of the device. The quick disassembly and assembly feature facilitates the staff to timely adjust the position and layout of the seedling bed according to the seedling cultivation process.

[0024] At the same time, when the device is arranged horizontally, fix the two fulcrums on the adjacent side, and use the engagement of the first limiting plate and the first trapezoidal limiting block to form an effective restraint in the horizontal direction, which can limit the relative displacement between components. Even when affected by external interference, the structure can maintain stability, preventing components such as the sealing cover and the seedling bed from sliding or misaligning horizontally. Compared with the traditional structure, it is simple in structure, reducing the manufacturing cost and installation difficulty, and avoiding affecting the growth of seedlings and water absorption due to structural shaking.

[0025] Provide stable restrictions on four fulcrums in the vertical direction. When subjected to gravity, the four fulcrums can disperse the pressure from different directions, effectively preventing displacement in the up and down or left and right directions, ensuring the stability of the overall structure, avoiding tipping or component detachment, and at the same time, while ensuring stability, maintaining the convenience of disassembly, achieving a good balance between stability and convenience.

[0026] The horizontal and vertical fixing methods of the device have strong versatility and flexibility. Whether arranged horizontally or vertically, its fixing structure can quickly adapt to different usage scenarios, meet the actual needs of different forestry seedling cultivation, and meet the special cultivation requirements of various seedlings. This fixing and disassembly design expands the application range of the device and can meet the actual needs of different forestry seedling cultivation. Brief Description of the Drawings

Detailed implementation manners

[0042] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0043] In the description of the present invention, the orientation or positional relationship indicated by the terms "center", "horizontal", "upper", "lower", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention.

[0044] The specific implementation of the present invention will be described in detail below in conjunction with specific embodiments.

[0045] The embodiment is as Figures 1 to 5 shown. A forestry seedling cultivation device provided by an embodiment of the present invention includes a seedling raising bed 11 and a sealing cover 12. The sealing cover 12 is slidably connected to the outer wall of the seedling raising bed 11, and there are three sealing covers 12 arranged linearly. A connecting component is provided on the outer side of the sealing cover 12;

[0046] The connecting component includes a first rectangular block 21. The first rectangular block 21 is fixedly connected to the outer wall of one of the sealing covers 12. Second rectangular blocks 22 are fixedly connected to the outer walls of the remaining two sealing covers 12. Limiting sliding grooves 23 are opened on the first rectangular block 21, the second rectangular blocks 22, and the top of the sealing cover 12. The limiting sliding grooves 23 are opened in an L shape, and the limiting sliding groove 23 on the side of the first rectangular block 21 away from the second rectangular block 22 and the sealing cover 12 to which it is fixedly connected is opened in an I shape. First limiting plates 24 are slidably connected inside the limiting sliding grooves 23, and each first limiting plate 24 can slide in every two limiting sliding grooves 23. An interference fit is formed between the first limiting plate 24 and the limiting sliding groove 23 to ensure the stability when the first rectangular block 21, the second rectangular blocks 22, and the sealing cover 12 are placed horizontally and fixed. First trapezoidal limiting blocks 25 are fixedly connected inside the limiting sliding grooves 23 of the second rectangular blocks 22 and the sealing cover 12. The first limiting plate 24 is rotatably connected inside the limiting sliding groove 23, and the first trapezoidal limiting block 25 is located on the movement track of the first limiting plate 24.

[0047] The connecting component further includes a second limiting plate 26 which is slidably connected to the bottoms of the two second rectangular blocks 22 and the remaining two sealing covers 12. Both the first limiting plate 24 and the second limiting plate 26 have a certain elasticity and are used to assist the first limiting plate 24 in being clamped on the second limiting plate 26. The second limiting plate 26 has an interference fit with the second rectangular blocks 22 and the remaining two sealing covers 12, which is used to ensure the stability when the first rectangular block 21, the second rectangular blocks 22, and the sealing covers 12 are vertically placed and fixed. Symmetrically fixed to the tops of the two second rectangular blocks 22 and the remaining two sealing covers 12 are second trapezoidal limiting blocks 27. The length of the limiting chute 23 is longer than the length of the first limiting plate 24, so that when the first limiting plate 24 is located inside the limiting chute 23, it will not intersect with the second trapezoidal limiting blocks 27. The second trapezoidal limiting blocks 27 are located on the movement track of the second limiting plate 26. The first limiting plate 24 and the second limiting plate 26 have the same shape, and the first trapezoidal limiting block 25 and the second trapezoidal limiting blocks 27 have the same shape. The first limiting plate 24 and the first trapezoidal limiting block 25 are both horizontally arranged, and the second limiting plate 26 and the second trapezoidal limiting blocks 27 are vertically arranged. The second trapezoidal limiting blocks 27 located on the movement track of the second limiting plate 26 are vertically arranged.

[0048] As Figures 6 to 12 shown, a connecting component is provided inside the first rectangular block 21 and the second rectangular blocks 22. The connecting component includes a three-way pipe 31 which is arranged inside the first rectangular block 21. Four-way pipes 32 are arranged inside both of the two second rectangular blocks 22. The three-way pipe 31 is communicated with the four-way pipes 32, which is used to ensure the circulation of water source inside the first rectangular block 21 and the second rectangular blocks 22. One end of the three-way pipe 31 is provided with a water inlet pipe 33. The remaining two ends of the three-way pipe 31 are both fixedly connected with sealing blocks 34. Also, the top ends and the ends far from the three-way pipe 31 of the four-way pipes 32 are both fixedly connected with sealing blocks 34. The lower ends and the ends close to the three-way pipe 31 of the four-way pipes 32 are both fixedly connected with connecting pipes 39, and the connecting pipes 39 are sleeved on the outer sides of the sealing blocks 34.

[0049] The connecting component further includes a fan-shaped groove block 35 which is fixedly connected to the inner wall of the sealing block 34. Three trigger holes 36 are annularly distributed inside the fan-shaped groove block 35. A first return spring 37 is fixedly connected to the center of the fan-shaped groove block 35. One end of the first return spring 37 far from the fan-shaped groove block 35 is fixedly connected with a sealing disc 38, and the fan-shaped groove block 35 and the sealing disc 38 cooperate with each other.

[0050] The connecting component also includes a water passing ring 310, which is fixedly connected to the inner wall of the connecting pipe 39, and a second return spring 311 is fixedly connected to the outer wall of the water passing ring 310, and a sealing plug 312 is fixedly connected to the end of the second return spring 311 away from the water passing ring 310, and a matching block 313 is fixedly connected to the inner wall of the connecting pipe 39, and the sealing plug 312 and the matching block 313 cooperate with each other. When the sealing plug 312 and the matching block 313 are in a sealed state, and the sealing plug 312 can only move toward the direction close to the water passing ring 310, and the outer wall of the matching block 313 is annularly distributed and fixedly connected with three resistance rods 314, and the resistance rods 314 are slidably connected to the inside of the trigger hole 36, and are used to resist the sealing disk 38 to assist the water source to flow, and the inside of the three-way pipe 31 and the four-way pipe 32 are both vertically arranged with two groups of water passing pipes 315, and the three water passing pipes 315 are a group, and the water passing pipes 315 pass through the inside of the sealing cover 12.

[0051] In combination with the above embodiments, the entire working process and working principle of the above embodiments are as follows:

[0052] Working principle:

[0053] After the sealing cover 12 and the nursery bed 11 are placed horizontally, when they need to be disassembled:

[0054] The staff first disassembles the second rectangular block 22 and the corresponding second limiting plate 26 on the top of the sealing cover 12, and the staff holds the first limiting plate 24 close to one end of the first trapezoidal limiting block 25 and rotates it to make the first limiting plate 24 break away from the restriction of the first trapezoidal limiting block 25;

[0055] Then, in the same manner as the above steps, the first limiting plate 24 on the top of the first rectangular block 21 is rotated again to achieve the purpose of separating the first rectangular block 21, the second rectangular block 22, and the sealing cover 12. Finally, the first limiting plate 24 is slid along the inside of the limiting groove 23 in the direction away from the first trapezoidal limiting block 25, so that the first limiting plate 24 is disengaged from the limitation of the first trapezoidal limiting block 25, and then the first limiting plate 24 is rotated to the inside of the limiting groove 23. Because the first limiting plate 24 and the limiting groove 23 are in an interference fit, the shaking of the first limiting plate 24 after being disengaged from the limitation of the first trapezoidal limiting block 25 is avoided.

[0056] After the sealing cover 12 and the nursery bed 11 are arranged horizontally, when they need to be fixed:

[0057] Contrary to the above movement process, the staff first pulls the first limit plate 24 in the limit slot 23 at the top of the first rectangular block 21 to rotate, so that the horizontal position of the end of the first limit plate 24 away from the limit slot 23 is higher than the first trapezoidal limit block 25 at the top of the second rectangular block 22;

[0058] Then, the first limiting plate 24 is pulled to move toward the first trapezoidal limiting block 25 at the top of the second rectangular block 22, and then the first limiting plate 24 is inserted into the outer wall of the first trapezoidal limiting block 25 at the top of the second rectangular block 22, so that the first limiting plate 24 is in conflict with the outer wall of the first trapezoidal limiting block 25 at the top of the second rectangular block 22, thereby achieving the purpose of fixing the first rectangular block 21 and the second rectangular block 22;

[0059] Then, the first limiting plate 24 on the top of the sealing cover 12 corresponding to the first rectangular block 21 is clamped on the outer wall of the first trapezoidal limiting block 25 again in the same manner as the above movement process, and then the assembly is carried out in sequence in the same manner as above.

[0060] When the first rectangular block 21, the second rectangular block 22 and the sealing cover 12 are arranged transversely, fixing two supporting points on one side adjacent to the first rectangular block 21, the second rectangular block 22 and the sealing cover 12 can form an effective constraint in the transverse direction and limit the relative displacement between the components.

[0061] When the sealing cover 12 and the nursery bed 11 are placed vertically:

[0062] At this time, the first rectangular block 21, the second rectangular block 22, and the sealing cover 12 are all fixed by the first limiting plate 24 and the first trapezoidal limiting block 25, and then the second rectangular block 22, the sealing cover 12, and the seedling bed 11 are stacked on top of the first rectangular block 21 and the corresponding sealing cover 12 in sequence;

[0063] The same as the step of the first limiting plate 24 being clamped into the first trapezoidal limiting block 25, the staff pulls the second rectangular block 22 and the second limiting plate 26 at the bottom of the sealing cover 12 respectively, so that the second limiting plate 26 is clamped on the outer wall of the second trapezoidal limiting block 27. In this process, the first limiting plate 24 rotates to the inside of the limiting slide groove 23, and thus will not affect the operation step of the second limiting plate 26 being clamped in the second trapezoidal limiting block 27, thereby achieving the first rectangular block 21, the second rectangular block 22, and the sealing cover 12. The four fulcrums on both sides adjacent to each other are fixed;

[0064] Furthermore, when the first rectangular block 21, the second rectangular block 22, and the sealing cover 12 are arranged vertically, each component is subject to the action of gravity and is prone to displacement in the up-down or left-right direction. Fixing with four fulcrums can provide stable support in different directions, thereby improving the fixing effect.

[0065] When the first rectangular block 21, the second rectangular block 22, the sealing cover 12, and the nursery bed 11 are arranged horizontally;

[0066] The connecting pipe 39 inside the second rectangular block 22 will be inserted into the sealing block 34 at one end of the first rectangular block 21 away from the water inlet pipe 33. At this time, the connecting pipe 39 drives the mating block 313 inside it and the three abutting rods 314 to be inserted into the sealing block 34, and the three abutting rods 314 will penetrate into the trigger holes 36 of the fan-shaped groove block 35 for sliding. When the connecting pipe 39 is inserted into the sealing block 34, the three abutting rods 314 sliding along the trigger holes 36 will abut the sealing disc 38 to move away from the fan-shaped groove block 35. At the same time, the sealing disc 38 will stretch the first return spring 37 away from the fan-shaped groove block 35. Thus, inside the sealing block 34 at one end of the first rectangular block 21 away from the water inlet pipe 33, there is a certain gap between the sealing disc 38 and the fan-shaped groove block 35 due to the abutment of the abutting rods 314;

[0067] At this time, inside the sealing block 34 at the top of the first rectangular block 21, without the abutment of the abutting rods 314, the first return spring 37 pulls the sealing disc 38 and the fan-shaped groove block 35 to fit together. Thus, one end at the top of the three-way pipe 31 is in a sealed state at this time;

[0068] And the four-way pipe 32 close to the first rectangular block 21 is connected to the three-way pipe 31 through the abutting rods 314 at this time. At this time, except for the end close to the first rectangular block 21, the other three ends of the four-way pipe 32 inside the second rectangular block 22 are still in a sealed state;

[0069] Thus, when an external water pipe is connected to the water inlet pipe 33 at this time, the water source will flow through the water inlet pipe 33 into the inside of the three-way pipe 31. At this time, one end at the top of the three-way pipe 31 is in a sealed state. Thus, the water source will flow along the inside of the sealing block 34 at one end of the first rectangular block 21 away from the water inlet pipe 33. Subsequently, the water source impacts the sealing plug 312 inside the second rectangular block 22 on the side close to the first rectangular block 21 along the gap between the sealing disc 38 and the fan-shaped groove block 35;

[0070] Subsequently, the impact force of the water source will cause the sealing plug 312 to squeeze the second return spring 311 towards the water passing ring 310. Thus, at this time, the water source flows into the inside of the connecting pipe 39 through the gap between the sealing plug 312 and the mating block 313. Finally, the water source inside the connecting pipe 39 will flow into the inside of the four-way pipe 32 through the water passing ring 310. At this time, except for the end close to the first rectangular block 21, the other three ends of the four-way pipe 32 inside are still in a sealed state. Thus, the water source flows into the inside of the seedling raising bed 11 through the four-way pipe 32, the three-way pipe 31, and the water passing pipe 315, and the water source will not leak.

[0071] Since the internal structures of the two second rectangular blocks 22, their corresponding sealing covers 12, and the seedling raising bed 11 are the same, when the remaining second rectangular block 22 is fixed on the side of the above-mentioned second rectangular block 22 away from the first rectangular block 21, the same movement process as above can still achieve the purpose of the water source flowing inside the three-way pipe 31 and the four-way pipe 32.

[0072] When the first rectangular block 21, the second rectangular block 22, the sealing cover 12, and the seedling bed 11 are arranged vertically;

[0073] Same as the above movement process, the connecting pipe 39 inside the second rectangular block 22 will be inserted into the sealing block 34 on the top of the first rectangular block 21. Subsequently, the three abutting rods 314 inside the connecting pipe 39 will simultaneously penetrate into the trigger holes 36. Then, the three abutting rods 314 will abut against the sealing disc 38 and move it away from the sector groove block 35. At the same time, the sealing disc 38 will stretch the first return spring 37 away from the sector groove block 35. Thus, inside the sealing block 34 at the end of the first rectangular block 21 away from the water inlet pipe 33, there is a certain gap between the sealing disc 38 and the sector groove block 35 due to the abutment of the abutting rods 314;

[0074] At this time, inside the sealing block 34 below the first rectangular block 21, the first return spring 37 pulls the sealing disc 38 and the sector groove block 35 to fit together. Thus, except for the part close to the water inlet pipe 33 and the top end, the three-way pipe 31 is in a sealed state;

[0075] At this time, the four-way pipe 32 inside the second rectangular block 22 on the top of the first rectangular block 21 is connected to the three-way pipe 31 through the abutting rods 314. At this time, except for the end close to the first rectangular block 22 inside the four-way pipe 32 of the second rectangular block 22, the other three ends are still in a sealed state;

[0076] Thus, when an external water pipe is connected to the water inlet pipe 33 at this time, the water source will flow through the water inlet pipe 33 into the inside of the three-way pipe 31. Then, the water source will rise along the three-way pipe 31. Subsequently, the water source impacts the bottom sealing plug 312 of the second rectangular block 22 on the side close to the first rectangular block 21 along the gap between the sealing disc 38 and the sector groove block 35, so that the water flow passes through the three-way pipe 31 and converges into the inside of the four-way pipe 32;

[0077] Since the internal structures of the two second rectangular blocks 22, the corresponding sealing covers 12, and the seedling beds 11 are the same, when the first rectangular block 21, the second rectangular block 22, the sealing cover 12, and the seedling bed 11 are arranged vertically, the same as the above movement process, the purpose of the water source flowing inside the three-way pipe 31 and the four-way pipe 32 can still be achieved.
