Description

Technical Field

[0001] This invention relates to the field of cultivation experiment technology, specifically to a multi-layer plant cultivation experimental device for plant ecology. Background Technology

[0002] Plant cultivation refers to propagating plants by respecting their growth characteristics and laws, and utilizing the parts of the plant that can grow and reproduce. With the development of agricultural modernization, in order to improve the survival rate and efficiency of plant cultivation, people move plants indoors for control, observe the growth activity patterns of plants and their relationship with the environment, and combine the results with production practice to conduct experimental analysis and obtain experimental results.

[0003] For example, patent (CN114557213A) describes a multi-layer plant cultivation control device for plant ecology. Through the coordinated operation of a timed start device, a servo motor, an active bevel gear, a driven bevel gear, a transmission rod, circular plates, a first transmission plate, and a second transmission plate, the servo motor can be activated over time, continuously adjusting the distance between several circular plates to provide sufficient production space for the plants and facilitate observation by staff. Patent (CN102599041A) describes an inflatable cultivation device, creating a novel cultivation device without a "tail," which is energy-saving, quiet, and free of electromagnetic pollution. It can fully utilize spaces such as rooms and balconies to grow various plants, beautifying the environment and improving air quality. It is evident that traditional cultivation devices, with their stacked layers, obstruct the light absorption of seedlings below, hindering their absorption of light. Furthermore, manual arrangement is time-consuming, labor-intensive, inefficient, and labor-intensive. Summary of the Invention

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: a multi-layer plant cultivation experimental device for plant ecology, comprising two bases, with multiple support plates fixedly arranged on the upper surface of each of the two bases, and a cultivation platform fixedly arranged on the upper end of each pair of the multiple support plates located in the same horizontal direction, with movable grooves opened on the upper surface of each of the multiple cultivation platforms, and guide grooves opened at the midpoint of the front and rear ends of the inner walls of each of the multiple movable grooves, with multiple cultivation mechanisms movably arranged in each of the multiple movable grooves, and storage boxes embedded in the lower surface of each of the multiple cultivation mechanisms, with water receiving boxes fixedly arranged on the rear end face of each of the multiple storage boxes, and the cultivation mechanism including a first cultivation box and a second cultivation box;

[0008] Among the multiple cultivation platforms, the rear end face of the cultivation platform near the middle position is fixedly provided with two fixed rods. The upper end of the opposite side of the two fixed rods is rotatably provided with a screw. A servo motor is fixedly provided at one end of the screw. A threaded block is threadedly sleeved on the outside of the screw. A support rod is fixedly provided at the midpoint of the front end face of the threaded block. A second water outlet is fixedly provided at the front end of the support rod. A fourth connecting rod is fixedly connected to the lower end face of the threaded block. The lower end of the fourth connecting rod is connected to a water tank through a pump body.

[0009] A second linkage rod is fixedly installed at the lower end of the front end face of the fourth connecting rod. A third connecting rod is fixedly installed at the front end face of the second linkage rod. A third linkage rod is fixedly installed at the lower end of the rear end face of the fourth connecting rod. A second connecting rod is fixedly connected to the rear end face of the third linkage rod, and a first linkage rod is fixedly connected to the lower end of the rear end face of the second connecting rod. A first connecting rod is fixedly connected to the rear end face of the first linkage rod. A first water outlet is fixedly installed at the upper end of the front end face of the first, second, and third connecting rods.

[0010] Fixed blocks are fixedly installed at the upper and lower ends of both sides of the inner wall of the storage box. Each of the four fixed blocks has a rotating shaft inside, and a baffle is fixedly sleeved on the outside of the shaft. Water pipes are fixedly installed at the lower ends of the opposite side of the first and second incubation boxes. Connecting shafts are movably embedded inside the multiple incubation tables. Multiple No. 1 cutting blocks are fixedly sleeved on the outside of the multiple connecting shafts. Linkage blocks are fixedly connected to one side of the lower end face of the first and second incubation boxes. Multiple rotating rods are movably installed inside the multiple incubation tables, and No. 2 cutting blocks are fixedly sleeved on the outside of the rotating rods.

[0011] Preferably, the plurality of the first cutting blocks are movably connected to the plurality of second cutting blocks respectively, and a rotating block is fixedly connected to one end of the connecting shaft and a limiting block is fixedly connected to the other end.

[0012] Preferably, the water receiving tank has a water inlet on its upper surface and a through hole on one side of its front end near the lower end, and a through groove is provided inside the storage tank near the rear end, the through groove communicating with the through hole.

[0013] Preferably, the multiple linkage blocks are respectively disposed on the outer side of the upper end face of the multiple second cutting blocks.

[0014] Preferably, both the first and second incubators have openings on their upper surfaces, and the storage box is embedded in the lower end of the opposite side of the first and second incubators.

[0015] Preferably, guide rods are fixedly provided on one side of the front end face and the rear end face of the first and second incubators, and the guide rods are movably embedded in the guide grooves.

[0016] Working Principle: When using this equipment, the plants to be grown in the experiment are planted in the first and second incubation boxes. Depending on the needs, the connecting shaft can be selectively moved using the rotating block. During this movement, the position of the outermost No. 1 cutting block changes. Moving the rotating block causes the connecting shaft to move back and forth, causing multiple No. 2 cutting blocks located on the outer side of the connecting shaft to move accordingly. Since one of each pair is in front and the other is behind, either the first or second incubation box located on the same storage box can be selectively disconnected from the storage box, thus completing a comparative experiment—one connected to nutrient solution, one not connected. This allows for adjustment of the displacement of either the first or second incubation box. Because the linkage block is fixed at the lower end of the incubation box, and the upper incubation box is inserted into the guide groove on the inner side of the cultivation platform via the front and rear guide rods, it causes a horizontal movement. When the first cutting block comes into contact with the second cutting block connected to the lower end of the first cultivation box via a linkage block, the connecting shaft is pulled, causing the second cutting block to move. Meanwhile, the front and rear ends of the first cultivation box are restricted within the guide groove by guide rods, allowing only lateral movement. During this movement, the water pipe of the first cultivation box detaches from the storage box, thus altering the growth environment of both the first and second cultivation boxes to create a comparative growth effect. Simultaneously, a servo motor and its output screw can drive the threaded block to move. The lateral movement of the threaded block will cause the water outlet, fixed by multiple connecting rods and linkage rods, to move, thereby completing the water injection operation for each water tank. Furthermore, by utilizing the different heights of the multiple cultivation platforms, not only can multiple sets of comparisons be formed, but the experimental results on the influence of height on plant growth can also be better obtained based on these different heights.

[0017] (III) Beneficial Effects

[0018] This invention provides a multi-layered plant cultivation experimental device for plant ecology. It has the following beneficial effects:

[0019] 1. This invention provides a multi-layer plant cultivation experimental device for plant ecology. By setting up multiple cultivation platforms, each cultivation platform contains multiple control cultivation experimental groups with a single variable that can be changed. Based on the completion of the change of the single variable, the cultivation comparison after the change of the single variable can be quickly obtained in the same environment. By selectively using the rotating block to pull the connecting shaft to change the position of the first cut piece relative to the second cut piece at the upper end of the connecting shaft, the synchronous adjustment of the same sample in the control experimental group can be achieved. This not only makes the operation simpler and more convenient to use, but also enables better collection and modification of experimental data.

[0020] 2. This invention provides a multi-layer plant cultivation experimental device for plant ecology. By setting two movable and tangentially fitting baffles on both sides of the inner wall of the storage box, when one cultivation box moves away from the storage box, the water pipe on one side of the cultivation box detaches, and the two baffles are no longer separated and are closed by the liquid thrust. This not only eliminates the need for manual adjustment of the closing state, but also enables a rapid change in the growth environment, so that the other cultivation box no longer receives nutrients from the storage box. At the same time, by utilizing the different heights of the multiple cultivation platforms, multiple sets of comparisons can be formed, and the experimental variables can be adjusted according to the different heights, so as to better obtain experimental results on the effect of height on plant growth.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example:

[0032] like Figure 1-8 As shown, this embodiment of the invention provides a multi-layer plant cultivation experimental device for plant ecology, including two bases 7. Multiple support plates 8 are fixedly arranged on the upper surface of each of the two bases 7. Cultivation platforms 9 are fixedly arranged on the upper end of each pair of the multiple support plates 8 located in the same horizontal direction. Movable grooves 11 are opened on the upper surface of each of the multiple cultivation platforms 9. Guide grooves 37 are opened at the midpoint of the front and rear ends of the inner wall of each of the multiple movable grooves 11. Multiple cultivation mechanisms 12 are movably arranged in each of the multiple movable grooves 11. Storage boxes 17 are embedded in the lower surface of each of the multiple cultivation mechanisms 12. Water collection boxes 16 are fixedly arranged on the rear end surface of each of the multiple storage boxes 17. The cultivation mechanism 12 includes a first cultivation box 1201 and a second cultivation box 1202.

[0033] Among the multiple cultivation platforms 9, the cultivation platform 9 near the middle position has fixed rods 13 on both sides of the rear end face. The upper part of the opposite side of the two fixed rods 13 is rotatably set with screws 14. A servo motor 36 is fixedly set at one end of the screw 14. A threaded block 30 is threadedly sleeved on the outside of the screw 14. A support rod 33 is fixedly set at the midpoint of the front end face of the threaded block 30. A second water outlet 32 ​​is fixedly set at the front end of the support rod 33. A fourth connecting rod 34 is fixedly connected to the lower end face of the threaded block 30. The lower end of the fourth connecting rod 34 is connected to a water tank through the pump body.

[0034] A second linkage rod 4 is fixedly installed at the lower end of the front face of the fourth connecting rod 34. A third connecting rod 5 is fixedly installed at the front face of the second linkage rod 4. A third linkage rod 35 is fixedly installed at the lower end of the rear face of the fourth connecting rod 34. A second connecting rod 2 is fixedly connected to the rear face of the third linkage rod 35, and a first linkage rod 3 is fixedly connected to the lower end of the rear face of the second connecting rod 2. A first connecting rod 1 is fixedly connected to the rear face of the first linkage rod 3. A first water outlet 6 is fixedly installed at the upper end of the front face of the first connecting rod 1, the second connecting rod 2, and the third connecting rod 5.

[0035] Fixed blocks 28 are fixedly installed at the lower ends of both sides of the inner wall of the storage box 17. A shaft 25 is rotatably installed inside each of the four fixed blocks 28, and a baffle 26 is fixedly sleeved on the outside of the shaft 25. Water pipes 27 are fixedly installed at the lower ends of the opposite side of the first incubation box 1201 and the second incubation box 1202. A connecting shaft 22 is movably embedded inside each of the multiple incubation tables 9. Multiple first-order cutting blocks 19 are fixedly sleeved on the outside of the multiple connecting shafts 22. A linkage block 29 is fixedly connected to one side of the lower end face of the first incubation box 1201 and the second incubation box 1202. Multiple rotating rods 20 are movably installed inside each of the multiple incubation tables 9, and second-order cutting blocks 21 are fixedly sleeved on the outside of the rotating rods 20.

[0036] When conducting plant ecology and growth experiments, the plants to be tested are transplanted into the first incubator 1201 and the second incubator 1202, such as... Figure 1 As shown, based on the different heights of the multiple cultivation platforms 9, plants of the same type are cultivated on cultivation platforms 9 at the same height. According to the control requirements, cultivation institutions 12 in the same combined body are selected. At this time, the cultivation and transplantation of plants are completed. Since the lower end of the fourth connecting rod 34 is connected to a water tank through the pump body, different experimental substances such as pure water and nutrient solution can be selected in the water tank as needed. The pump body passes through multiple connecting rods through water pipes and is connected to the water outlet. A nozzle is set at the water outlet. The nozzle is directly connected to the water inlet 15 at the upper end of the water tank 16 to complete the addition of nutrients. The upper end face of the water tank 16 has a water inlet 15 and a through hole 24 is opened at the lower end of the front side. A through groove 18 is opened at the rear end of the storage box 17. The through groove 18 is connected to the through hole 24.

[0037] When adding substances, the servo motor 36 starts and drives the screw 14 to rotate. The screw 14 is threaded with a threaded block 30 on the outside. Multiple water outlets are linked and fixed with the threaded block 30 through the linkage rod, connecting rod and support rod 33. When the threaded block 30 moves along the screw 14, the lateral displacement of the entire adding mechanism is completed. At this time, the substances are injected into the water receiving tank 16 and flow through the through hole 24 to the through groove 18. Finally, the nutrients are collected in the storage tank 17 for storage.

[0038] When it is necessary to form a controlled experiment with a single variable change, such as Figure 5 and 8 As shown, pulling the rotating block 23 causes the connecting shaft 22 connected to it to shift, while the other side of the connecting shaft 22 is fixed with a limit block 10, which can effectively prevent it from falling off due to excessive pulling. When the connecting shaft 22 is pulled, the position of the first cutting block 19 fixedly sleeved on the outside of the connecting shaft 22 changes. It can be selected to fit with the second cutting block 21 at the lower end of the first incubator 1201 or the second cutting block 21 at the lower end of the second incubator 1202 as needed. Since the second cutting block 21 is fixedly sleeved on the rotating rod 20 and its upper end is connected to the incubator through the linkage block 29, the linkage block 29 is fixedly connected to the incubator. The front and rear ends of the incubator are embedded in the guide grooves 37 in the movable groove 11 at the upper end of the incubator 9 via guide rods 31. When the second cut piece 21 is displaced, the linkage block 29 moves accordingly, allowing the incubator to move laterally. At this time, when the first incubator 1201 or the second incubator 1202 is displaced, the water pipe 27 on one side is detached from the storage box 17. At this time, the two baffles 26 on the inner side no longer separate and are sealed under the pressure of the internal material. After the water pipe 27 is detached, it no longer receives nutrients, thereby changing the growth environment variables between the two incubators.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
