Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0026] Example

[0027] Please refer to Figures 1 to 5 This utility model provides a soilless cultivation device. It includes a cultivation container 1, a cultivation panel 2, multiple planting baskets 4, multiple lifting guide rods 5, and multiple connecting components. The cultivation panel 2 is installed on the top of the cultivation container 1, forming a cover on the top of the container 1. This not only prevents external impurities from entering the container 1 but also reduces the evaporation loss of the nutrient solution inside. The cultivation panel 2 has multiple planting holes 3, and the multiple planting baskets 4 are distributed one-to-one with the planting holes 3. The planting baskets 4 are movably fitted into the corresponding planting holes 3, allowing them to move up and down along the axis of the planting holes 3. Multiple lifting guide rods 5 are respectively installed on the cultivation panel 2, and each lifting guide rod 5 is arranged in the edge area of ​​the corresponding planting hole 3; one end of multiple connecting components is movably connected to the corresponding lifting guide rod 5, and the other end is connected to the corresponding planting basket 4. The connecting components have a locking function, which can form a lock at the preset height position of the lifting guide rod 5, thereby driving the planting basket 4 to be synchronously fixed at the preset height, so as to realize the control of the immersion depth of the planting basket 4 in the nutrient solution in the cultivation container 1.

[0028] In practical application, a set amount of nutrient solution is first injected into the cultivation container 1, and then the plant to be cultivated is placed into the planting basket 4. Filling materials such as ceramsite or sponge blocks can be embedded in the gap between the planting basket 4 and the plant to achieve the positioning of the plant in the planting basket 4. The root system of the plant can extend into the cultivation container 1 through the hollow structure at the bottom of the planting basket 4, thereby contacting the nutrient solution and completing the absorption of nutrients and water.

[0029] Because different plants have different root physiological characteristics, and the same plant's root absorption efficiency and tolerance to immersion depth vary at different growth stages such as seedling, growth period, and maturity, if the nutrient solution submerges the roots too deeply, it can easily lead to root hypoxia, suffocation, and rot; if the submersion is too shallow, it will result in insufficient nutrient absorption by the roots, affecting plant growth. Therefore, it is necessary to specifically control the contact position between the nutrient solution surface and the plant roots according to the type and growth stage of the cultivated object. At this time, the operator can independently adjust each planting basket 4, and by driving the corresponding connecting component to move along the lifting guide rod 5 to the target height and lock it, the planting basket 4 can be fixed at the preset height, so that the roots of the plant in the planting basket 4 are exactly at the set contact depth of the nutrient solution, meeting the personalized needs of plant growth.

[0030] Please refer to Figure 2 In some embodiments of this application, the connecting assembly includes a sleeve 10 and a connecting rod 9. The sleeve 10 is coaxially fitted onto the outside of the lifting guide rod 5, forming a sliding fit in the length direction. The sleeve 10 and the lifting guide rod 5 can be detachably locked at a preset height. One end of the connecting rod 9 is connected to the sleeve 10, and the other end is connected to the planting basket 4, forming a force transmission structure. When the sleeve 10 slides along the lifting guide rod 5 to the preset height and locks, the connecting rod 9 can drive the planting basket 4 to be synchronously positioned at the preset height, thereby achieving height adjustment of the planting basket 4.

[0031] The sleeve 10 is equipped with a locking component 6, and the lifting guide rod 5 has several spaced locking through holes 7 along its own axis. The locking through holes 7 at a preset height can lock with the locking component 6. When the sleeve 10 moves up or down along the length of the lifting guide rod 5, it can synchronously drive the locking component 6 to move in the same direction, so that the locking component 6 locks with the locking through holes 7 at different positions, thereby achieving the positioning of the sleeve 10 on the lifting guide rod 5.

[0032] Please refer to Figure 4 Specifically, the locking assembly 6 consists of a locking seat 11, a locking pin 15, and a first spring 22; the locking seat 11 is machined with a receiving groove 21 and is assembled on the top end face of the sleeve 10; the locking pin 15 is slidably inserted into the receiving groove 21 and has the ability to extend and retract along the axial direction of the receiving groove 21; the first spring 22 is coaxially mounted on the outside of the locking pin 15, with one end of the first spring 22 connected to the outer wall of the locking pin 15 and the other end connected to the inner wall of the receiving groove 21.

[0033] When adjusting the height of the sleeve 10, the operator applies a pulling force to the locking pin 15 in the direction away from the locking through hole 7, causing the first spring 22 to compress and deform against its own elastic force until the locking pin 15 is completely disengaged from the currently engaged locking through hole 7, and the locking state between the sleeve 10 and the lifting guide rod 5 is released. Then, the sleeve 10 is driven to move up and down along the axis of the lifting guide rod 5. After the sleeve 10 moves to the preset height position, the operator removes the pulling force on the locking pin 15. The first spring 22 extends and resets under the action of elastic restoring force, pushing the locking pin 15 to re-engage in the corresponding locking through hole 7, thus completing the height positioning and relocking of the sleeve 10.

[0034] Please refer to Figure 1 In some embodiments of this application, the planting holes 3 of the cultivation panel 2 are arranged in a matrix array, and the sleeves 10 distributed in the same row laterally are integrated with a linkage mechanism to realize the synchronous or independent switching of multiple sleeves 10; the locking seat 11 is composed of a supporting base 13 and a locking base 12, and the supporting base 13 and the locking base 12 form a slidable assembly relationship through a guide structure. The supporting base 13 is sequentially machined with a first positioning hole 18 and a second positioning hole 17 along the sliding path of the locking base 12. The positioning component installed on the locking base 12 has the function of selectively embedding into the two positioning holes, thereby realizing the switching of the working state of the locking seat 11.

[0035] When the locking seat 11 is in the first state, the positioning component forms a rigid positioning engagement with the first positioning hole 18. At this time, the locking function of the locking base 12 is activated, and it can form a lock with the locking through hole 7 of the lifting guide rod 5. At the same time, the linkage engagement mechanism of each sleeve 10 in the horizontal row can be in a separated state. Each sleeve 10 can be independently raised and lowered along the corresponding lifting guide rod 5 to drive the corresponding planting basket 4 to achieve height adjustment, adapting to the differentiated height requirements of different plant species or different growth stages.

[0036] When the locking seat 11 is switched to the second state, the positioning component and the second positioning hole 17 form a positioning engagement, the locking function of the locking base 12 is released, and the locking base 12 is disengaged from the locking through hole 7. At this time, one of the locking seats 11 of the multiple sleeves 10 in the same row can be kept in the first state, and the locking seats 11 of the other sleeves 10 are switched to the second state. The sleeve 10 in the first state can drive the other sleeves 10 in the second state to achieve synchronous lifting and lowering through the linkage engagement mechanism. After the whole is moved to the preset height, the height positioning of all planting baskets 4 in the same row can be completed by locking the locking seat 11 in the first state and the locking through hole 7, which significantly improves the efficiency of the coordinated adjustment of multiple sleeves 10 and meets the batch height control needs of the same type of plant or plants in the same growth stage.

[0037] Please refer to Figure 3 and Figure 4It should be noted that the upper surface of the supporting base 13 is provided with a groove 19 extending along a preset trajectory, and the lower surface of the locking base 12 is correspondingly fitted with a slider 20 adapted to the groove 19. The engagement of the groove 19 and the slider 20 forms an anti-disengagement sliding guide. At the same time, the receiving channel 21 is opened through the locking base 12 along the thickness direction. When the locking base 12 slides along the groove 19 of the supporting base 13, it can simultaneously drive the receiving channel 21 and the locking pin 15 in the receiving channel 21 to translate, thereby realizing the locking pin 15 and the corresponding locking through hole 7 to lock and conduct or lock and block, thereby switching the engagement state of the locking component 6 and the locking through hole 7.

[0038] Please refer to Figure 5 In some embodiments of this application, the positioning component includes a positioning body 14, a positioning pin 16, and a second spring 24. The positioning body 14 is mounted on the side wall of the locking base 12, and an assembly groove 23 is provided on the positioning body 14. The positioning pin 16 is slidably inserted into the assembly groove 23. The second spring 24 is sleeved on the outer periphery of the positioning pin 16, with one end connected to the outer wall of the positioning pin 16 and the other end connected to the inner wall of the assembly groove 23. The second spring 24 remains extended in its natural state and has the function of applying a pushing force to the positioning pin 16, which can drive the positioning pin 16 to be inserted into the first positioning hole 18 or the second positioning hole 17.

[0039] When the locking base 12 is displaced relative to the supporting base 13, the positioning body 14 moves synchronously with the locking base 12, causing the positioning pin 16 to align with the first positioning hole 18 or the second positioning hole 17. At this time, the thrust of the second spring 24 drives the positioning pin 16 to insert into the corresponding positioning hole, thereby fixing the position of the locking base 12. When the positioning is released, the positioning pin 16 is pulled by an external force, causing the positioning pin 16 to disengage from the currently mating positioning hole, thus releasing the constraint.

[0040] Please refer to Figure 1 In some embodiments of this application, a linkage shaft 8 is provided between two adjacent sleeves 10, and the two ends of the linkage shaft 8 are respectively detachably connected to the corresponding sleeves 10. When the two ends of the linkage shaft 8 are assembled with the adjacent sleeves 10, the adjacent sleeves 10 can form a linkage relationship, providing a structural basis for unified adjustment operations in the same planting scenario; when the linkage shaft 8 is disassembled from the adjacent sleeves 10, the linkage state between the adjacent sleeves 10 is immediately released.

[0041] For example, the connection between the linkage shaft 8 and the corresponding sleeve 10 can be achieved through various structures: the two ends of the linkage shaft 8 are connected to the sleeve 10 by bolts. Bolt connection is existing technology and will not be described in detail here. It can realize quick assembly and disassembly of the linkage shaft 8 and the sleeve 10.

[0042] Furthermore, a bushing joint can be installed on the sleeve 10, and an elastic layer (rubber) can be assembled on the inner wall of the bushing joint. When both ends of the linkage shaft 8 are embedded in the bushing joint, the elastic layer can fix the linkage shaft 8 through the clamping force generated by its own deformation, thereby completing the connection limit.

[0043] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
