Description

Technical Field

[0001] This invention relates to the field of agricultural product cultivation equipment technology, specifically to a cultivation device for testing new varieties of agricultural technology. Background Technology

[0002] A crop cultivation and incubation chamber is a device used for agricultural research, crop cultivation, and experimentation, primarily to simulate crop growth under different environmental conditions. It is typically equipped with control systems for temperature, humidity, light, and ventilation, helping researchers conduct crop cultivation, breeding, and experimental research in a controlled environment. This device allows for precise control of environmental parameters, enabling the study of the effects of various factors on crop growth. For example, a crop cultivation experiment incubator with publication number CN224069294U belongs to the technical field of crop incubators. This crop cultivation experiment incubator includes an incubator, a placement rack, planting pots, connecting rods, vine rods, and positioning frames. The placement rack is fixedly connected inside the incubator; multiple planting pots are placed on the placement rack; multiple connecting rods are movably connected to the inner wall of the top of the incubator; vine rods are fixedly connected to the connecting rods; and multiple positioning frames are rotatably connected to the vine rods. By setting up vine rods and utilizing multiple rotatable positioning frames, the vines of the crop can be fixed to the vine rods, effectively supporting vine-type crops and improving the practicality of the device. At the same time, the connecting rods facilitate the assembly and disassembly of the vine rods.

[0003] While the existing technical solutions involved in the aforementioned patents can achieve relevant beneficial effects, they still have certain limitations. Specifically, in the process of crop cultivation, multiple pots of the same crop variety are usually planted in the cultivation box. Due to the limited space inside the cultivation box, the spacing between adjacent crop samples is small. When it is necessary to remove one of the crop samples for observation, testing, or other operations, it is very easy to touch or scratch the adjacent crop samples during the operation, thereby damaging the seedlings, roots, or leaves of the adjacent samples, affecting the integrity and accuracy of the sample cultivation, and failing to meet the actual operational needs in the process of crop sample cultivation.

[0004] Therefore, we have proposed a breeding device for testing new varieties of agricultural technology to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a cultivation device for testing new varieties of agricultural technology, in order to solve the problem mentioned in the background art that when it is necessary to take out one of the crop samples for observation, testing and other operations, it is very easy to touch or scratch the adjacent crop samples during the operation, thereby damaging the seedlings, roots or leaves of the adjacent samples, affecting the integrity and accuracy of the sample cultivation, and failing to meet the actual operation requirements in the crop sample cultivation process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cultivation device for testing new varieties of agricultural technology extension, comprising an outer shell mechanism and a pull-out mechanism disposed on one side of the outer shell mechanism, wherein a cultivation mechanism is further disposed at the upper end of the outer shell mechanism, the cultivation mechanism comprising a cultivation pot disposed at the upper end of the pull-out mechanism, and a through hole is provided at the bottom of the cultivation pot; The outer shell mechanism is provided with a flow guiding mechanism, which includes multiple equidistant transverse sleeves. Both ends of the multiple transverse sleeves are connected to a longitudinal sleeve, and multiple equidistant first flow pipes are provided on one side of the transverse sleeves. The outer shell mechanism is equipped with a protective mechanism, which includes a water bladder bag disposed around the outer periphery of the cultivation pot. The water bladder bag is connected to the transverse sleeve through the first flow tube, and the inner wall of the water bladder bag has a liquid outlet circumferentially opened.

[0007] Preferably, the outer shell mechanism includes an outer shell body, a liquid storage tank is provided at the bottom of the inner part of the outer shell body, an injection pipe is fixedly installed at one end of the liquid storage tank and inserted into the outer shell body, and a limit plate is fixedly installed on the inner wall of the outer shell body.

[0008] Preferably, the pull-out mechanism includes a side plate disposed on one side of the outer casing and a handle fixedly installed on one side of the side plate. A load-bearing plate is fixedly installed at the end of the side plate away from the handle, and the two ends of the load-bearing plate overlap the upper end of the limiting plate.

[0009] Preferably, the upper end of the load-bearing plate is provided with a plurality of equidistant through holes and a first magnetic strip. The through holes are connected to the transverse sleeve. The plurality of through holes are arranged in a rectangular array with the cultivation pot at intervals. The through holes are also spaced apart from the first magnetic strip.

[0010] Preferably, a plurality of second magnetic strips are evenly distributed at the upper end of the transverse sleeve, one second magnetic strip overlaps two transverse sleeves, and the second magnetic strip and the first magnetic strip exhibit a magnetic repulsion phenomenon.

[0011] Preferably, the water bag is a cylindrical structure with openings at the top and bottom, with its upper end curled inward and enclosing the cultivation pot within it.

[0012] Preferably, a telescopic strip is fixedly installed at the upper end of the water bladder, an annular reinforcing strip is fixedly installed on the outer periphery of the lower end of the water bladder, a reinforcing frame is fixedly installed at the upper end of the annular reinforcing strip, and the reinforcing frame is fixedly installed on the outer wall of the water bladder.

[0013] Preferably, the lower end of the water bladder is connected to a support cylinder via a second connecting pipe. The support cylinder is mounted on the load-bearing plate. A corrugated pipe is connected to the upper end of the support cylinder. The corrugated pipe is located at the lower end of the cultivation pot. An inner pipe is connected to the upper end of the corrugated pipe. The inner pipe passes through the through hole into the inside of the cultivation pot.

[0014] Preferably, the outer shell mechanism is further provided with a connecting mechanism, which is adapted to the protective mechanism. The connecting mechanism includes a pressing frame that overlaps the upper end of the adjacent second magnetic strip. The pressing frame is disposed on the outer periphery of the water bag. An elastic element is fixedly installed at the lower end of the pressing frame. The elastic element is fixedly installed at the upper end of the load-bearing plate. A height measuring ruler is fixedly installed at the upper end of the pressing frame.

[0015] Preferably, a damping slider is slidably mounted on the upper end of the height measuring ruler, and a flexible measuring tape is rotatably mounted on the outer periphery of the damping slider.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up a coordinated mechanism for the outer shell, pull-out mechanism, cultivation mechanism, flow guiding mechanism, and protective mechanism, the problem of small spacing between adjacent samples and easy scratching during removal in existing cultivation devices is effectively solved. When a cultivation pot needs to be removed, the entire pull-out mechanism is pulled out of the outer shell by the handle. At this time, the load-bearing plate drives the cultivation pot, water bag, and other structures above to move out simultaneously, realizing simultaneous cultivation of multiple samples and improving the standardization of the experiment.

[0017] 2. Since the transverse sleeve and the longitudinal sleeve in the flow guiding mechanism form a liquid flow network, liquid can be injected into the storage tank through the injection pipe during the pulling process. The liquid enters the transverse sleeve through the through hole and flows into the water bag through the first flow pipe. The liquid flowing out of the outlet on the water bag can accurately replenish the roots of the crops in the cultivation pot, ensuring a stable cultivation environment.

[0018] 2. The water bladder bag adopts a cylindrical structure with openings at the top and bottom. Its upper end is rolled inward, and the rolled part unfolds and extends upward, which can adaptively adjust the protection range according to the growth height of the crop, avoiding pressure on the crop stem. When it is filled with liquid and expands, a clear gap is formed between the water bladder bag and the adjacent water bladder bags, so that the operator can easily remove the cultivation pot from the support plate without touching or scratching the adjacent crop samples.

[0021] 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.

[0022] Example 1: Please refer to Figures 1-9A cultivation device for testing new varieties of agricultural technology includes an outer shell 1 and a pull-out mechanism 2 located on one side of the outer shell 1. A cultivation mechanism 3 is also provided at the upper end of the outer shell 1. The cultivation mechanism 3 includes cultivation pots 31 located at the upper end of the pull-out mechanism 2. The bottom of the cultivation pots 31 has a through hole 32. Multiple cultivation pots 31 are arranged inside the outer shell 1 in a rectangular shape. Crop samples are cultivated in the cultivation pots 31. The through hole 32 can filter excess water and nutrients, avoid water and fertilizer accumulation in the cultivation pots 31 which would lead to root rot, effectively ensure the air permeability of the cultivation environment for crop samples, reduce the risk of root rot, and at the same time, the multiple rectangular cultivation pots 31 can make full use of the internal space of the outer shell 1 to realize the simultaneous cultivation of multiple samples and improve the standardization of the experiment.

[0023] The outer shell mechanism 1 includes an outer shell 11. A liquid storage tank 12 is provided at the bottom inside the outer shell 11. A liquid injection pipe 13 is fixedly installed at one end of the liquid storage tank 12 and is inserted and connected to the outer shell 11. One end of the liquid injection pipe 13 is connected to a water pump and connected to a container containing nutrient solution. A limit plate 14 is fixedly installed on the inner wall of the outer shell 11. The limit plate 14 is used to support and limit the pull-out mechanism 2, ensuring that the pull-out mechanism 2 slides smoothly, avoiding deviation during the sliding process, preventing tilting when pulled out or pushed in, and protecting the cultivation pot 31 and the crop samples inside from damage.

[0024] The pull-out mechanism 2 includes a side plate 21 disposed on one side of the outer shell 11 and a handle 22 fixedly installed on one side of the side plate 21. A load-bearing plate 23 is fixedly installed at the end of the side plate 21 away from the handle 22. The two ends of the load-bearing plate 23 overlap the upper end of the limiting plate 14. All the cultivation pots 31 are distributed on the load-bearing plate 23. The operator holds the handle 22 and pulls the side plate 21 outward to completely remove the load-bearing plate 23 and the cultivation pots 31 on its upper end from the outer shell 11 without having to move the cultivation pots 31 one by one. This effectively solves the problem of small spacing between multiple samples and easy damage to adjacent samples when removing them in the existing device.

[0025] The upper end of the load-bearing plate 23 is provided with multiple equidistant through holes 24 and a first magnetic strip 25. The through holes 24 are connected to the transverse sleeve 41. The multiple through holes 24 and the cultivation pot 31 are arranged in a rectangular array with intervals. The through holes 24 and the first magnetic strip 25 are arranged with intervals.

[0026] The outer casing 1 is provided with a flow guiding mechanism 4. The flow guiding mechanism 4 includes multiple equidistant transverse sleeves 41. Both ends of the multiple transverse sleeves 41 are connected to a longitudinal sleeve 42. Multiple equidistant first flow pipes 43 are provided on one side of the transverse sleeves 41. The outer shell mechanism 1 is equipped with a protective mechanism 5. The protective mechanism 5 includes a water bag 51 disposed around the outer periphery of the cultivation pot 31. The water bag 51 is connected to the transverse sleeve 41 through the first flow pipe 43. The inner wall of the water bag 51 is provided with a liquid outlet 52 in the circumferential direction.

[0027] When the water pump is turned on, it injects the nutrient solution used to nourish the crop samples into the storage tank 12. The liquid in the storage tank 12 has only one outlet, the through hole 24. Therefore, the nutrient solution enters the horizontal sleeve 41 and the vertical sleeve 42 through the through hole 24, and then enters the water bag 51 through the first flow tube 43. Finally, it flows out from the outlet 52, which is downward and drips precisely into the cultivation pot 31, accurately landing on the substrate surface inside the cultivation pot 31 to provide nutrients for the crop samples.

[0028] Example 2: Please refer to Figures 1-9 Multiple second magnetic strips 44 are evenly distributed at the upper end of the transverse sleeve 41. One second magnetic strip 44 overlaps two transverse sleeves 41. The second magnetic strip 44 and the first magnetic strip 25 exhibit magnetic repulsion, which can reduce the friction between the transverse sleeve 41 and the load-bearing plate 23, extend the service life of the device, and ensure that the through hole 24 is accurately connected to the transverse sleeve 41, ensuring the smooth delivery of nutrient solution. The through hole 24 is located between two adjacent second magnetic strips 44 and is adapted to the cultivation pot 31. During the process of nutrient solution dripping into the cultivation pot 31, due to the repulsion between the first magnetic strip 25 and the second magnetic strip 44, the transverse sleeve 41 remains stable, ensuring that the nutrient solution is evenly distributed to each water bag 51.

[0029] The water sac 51 is a cylindrical structure with openings at the top and bottom. The opening at the top is larger than the opening at the bottom, and the top is rolled inward, enclosing the cultivation pot 31 inside.

[0030] A telescopic strip 53 is fixedly installed at the upper end of the water bladder 51, and an annular reinforcing strip 54 is fixedly installed on the outer periphery of the lower end of the water bladder 51. A reinforcing frame 55 is fixedly installed at the upper end of the annular reinforcing strip 54. The reinforcing frame 55 is fixedly installed on the outer wall of the water bladder 51. The annular reinforcing strip 54 and the reinforcing frame 55 are used to support the water bladder 51. The reinforcing frame 55 can also adapt to the deformation of the water bladder 51 as its shape changes.

[0031] The lower end of the water bag 51 is connected to a support cylinder 57 via a second connecting pipe 56. The support cylinder 57 is mounted on the load-bearing plate 23. The upper end of the support cylinder 57 is connected to a corrugated pipe 58, which is in a naturally contracted state. The corrugated pipe 58 is located at the lower end of the cultivation pot 31. The upper end of the corrugated pipe 58 is connected to an inner pipe 59, which passes through the through hole 32 into the inside of the cultivation pot 31.

[0032] When the operator removes the sample, the water pump is increased. The outlet 52 and the inner tube 59 have smaller diameters, and the liquid flow rate is greater than the liquid flow rate from the outlet 52 and the inner tube 59. As the water pump is turned on, the water bag 51 and the corrugated tube 58 can be unfolded. When the water bag 51 unfolds, it unfolds outward, adapting to the shape of plant leaves growing from bottom to top, so it will not damage the crop leaves. After the water bag 51 is fully unfolded, it has a trumpet-shaped structure with the upper opening larger than the lower opening, allowing the cultivation pot 31 and crop sample inside to be completely removed, making it easy for the operator to remove. The corrugated tube 58 unfolds after the water bag 51. After unfolding, the corrugated tube 58 can raise the cultivation pot 31, further increasing the convenience of sample removal. Multiple water bags 51 move simultaneously until they fit together, making it easy to remove the material.

[0033] Since the water pump is always on, there is still nutrient solution left in the cultivation pot 31 after the material is removed, and the cultivation pot 31 can be stored for a relatively long time after removal.

[0034] Example 3: Please refer to Figures 1-9 The outer shell mechanism 1 is also provided with a connecting mechanism 6. The connecting mechanism 6 is adapted to the protective mechanism 5. The connecting mechanism 6 includes a pressing frame 61 that overlaps the upper end of the adjacent second magnetic strip 44. The pressing frame 61 is set on the outer periphery of the water bag 51. An elastic element 62 is fixedly installed at the lower end of the pressing frame 61. The elastic element 62 is fixedly installed at the upper end of the load-bearing plate 23. A height measuring ruler 63 is fixedly installed at the upper end of the pressing frame 61.

[0035] A damping slider 64 is slidably mounted on the upper end of the height measuring ruler 63. The starting scale of the height measuring ruler 63 is consistent with the height of the cultivation pot 31. A flexible measuring tape 65 is rotatably mounted on the outer periphery of the damping slider 64. By lifting the damping slider 64 upward and rotating the flexible measuring tape 65 to the top of the crop, the height of the crop can be measured. If it is necessary to measure the diameter of a specific part of the stem or to perform more detailed dimensional measurements, the flexible measuring tape 65 on the outer periphery of the damping slider 64 can be rotated and placed around the corresponding part of the crop to read the scale value on the flexible measuring tape 65. After the measurement is completed, the damping slider 64 is slid back to its initial position.

[0036] When a single crop sample needs to be taken for observation and testing, the operator first locates the height gauge 63 corresponding to the sample location and presses it down. The height gauge 63 causes the pressing frame 61 to move downwards, squeezing the elastic element 62 at its lower end. At the same time, pressure is applied to the second magnetic strip 44 below. Under the pressure, the second magnetic strip 44 overcomes the repulsive force with the first magnetic strip 25, causing the transverse sleeve 41 to compress downwards. At this time, the communication state between the transverse sleeve 41 and the longitudinal sleeve 42 in the area covered by the pressing frame 61 changes locally, resulting in a larger water inflow and pressure in the through hole 24 in this area compared to other areas. More nutrient solution quickly enters the corresponding water through the first flow tube 43. The water bag 51 enters the support cylinder 57 through the second connecting pipe 56. Due to the small diameter of the outlet 52 and the inner tube 59, the inflow velocity of the liquid is greater than the outflow velocity. Under the action of liquid pressure, the water bag 51 expands outward, and the telescopic strip 53 at its upper end is stretched. The reinforcing frame 55 supports the water bag 51 to form a funnel-shaped structure with the upper opening larger than the lower opening, so as to avoid damage to the crop leaves. Subsequently, the corrugated pipe 58 extends upward under liquid pressure, pushing the cultivation pot 31 upward, further increasing the operating space for sample removal. At this time, a clear gap is formed between the water bag 51 and the adjacent water bag 51, and the operator can easily remove the cultivation pot 31 from the load-bearing plate 23 without touching or scratching the adjacent crop sample.

[0037] If it is necessary to perform unified operation on multiple or all crop samples or to clean and maintain the inside of the device, the operator can hold the handle 22 of the pull-out mechanism 2 and pull the side plate 21 outward. The side plate 21 drives the load-bearing plate 23 to slide along the limiting plate 14, so that the load-bearing plate 23 and all the cultivation pots 31, the flow guiding mechanism 4, the protective mechanism 5, etc. on it can be completely pulled out from the outer shell 11, which is convenient for batch operation or thorough cleaning of components such as the liquid storage tank 12 and the horizontal sleeve 41. After the operation is completed, the load-bearing plate 23 is pushed back into the outer shell 11, so that the side plate 21 is reset and fits against the outer shell 11.

[0038] Special Case Handling (When Nutrient Solution is Saturated): When the nutrient solution in the substrate of the cultivation pot 31 reaches saturation and no further liquid supply is needed, the water pump connected to the injection pipe 13 can be replaced with an air pump. The air pump injects air into the storage tank 12 through the injection pipe 13. The air enters the water bag 51 through the through hole 24, the horizontal sleeve 41, and the first flow pipe 43, and then exits from the outlet 52, or enters the substrate inside the cultivation pot 31 through the second connecting pipe 56, the corrugated pipe 58, and the inner pipe 59, increasing the oxygen content in the soil, promoting root respiration, and preventing root rot due to oxygen deficiency caused by oversaturation of the nutrient solution.

[0039] After completing sample observation, testing, or maintenance, if the removed sample needs to be returned, place the cultivation pot 31 back in its original position, ensuring that the inner tube 59 is inserted into the through hole 32, turn off the water pump (or air pump), and the liquid (or gas) in the water bag 51 and the corrugated tube 58 will gradually be discharged and return to its initial state under its own elasticity and gravity. The upper end of the water bag 51 will curl inward again to wrap the cultivation pot 31, and the pressing frame 61 will return to its original position under the restoring force of the elastic element 62. The second magnetic strip 44 and the first magnetic strip 25 will return to their like-pole repulsive state, the horizontal sleeve 41 will return to its initial position, and the device will return to normal cultivation state.
