Detailed implementation manners

[0030] Embodiment

[0031] The following is further described in conjunction with specific embodiments. As shown in the attached Figure 1 - attached Figure 13As shown in the figure, the research device for the micro-landscape plant propagation technology in this embodiment includes a box body 10, friction strips 12 vertically arranged on the inner wall of the box body 10, a main shaft 13 vertically arranged in the box body 10, a driving device for driving the main shaft 13 to rotate, a light source 14 arranged on the outer wall of the main shaft 13, a plurality of culture devices 20 arranged in a circular pattern around the outer wall of the main shaft 13, and a water supply device 30 connected to the culture device 20; the culture device 20 includes a vertically arranged culture cylinder 21, water seepage holes 22 opened on the side wall of the culture cylinder 21, a fiber mesh 23 wound around the outer wall of the culture cylinder 21, a first connecting rod 25 connected to the side wall of the upper end of the main shaft 13, and a second connecting rod 26 connected to the side wall of the lower end of the main shaft 13; both ends of the culture cylinder 21 are rotatably connected to the first connecting rod 25 and the second connecting rod 26 respectively; the thickness of the friction strip 12 is greater than the distance between the outer wall of the culture cylinder 21 and the inner wall of the box body 10. Specifically, when in use, plant seeds or seedlings are buried in the fiber mesh 23, then the fiber mesh 23 is wound around the outer wall of the culture cylinder 21, and then both ends of the culture cylinder 21 are connected to the first connecting rod 25 and the second connecting rod 26 respectively, and the water supply device 30 is connected to the culture cylinder 21. The water supply device 30 sends water into the interior of the culture cylinder 21 and seeps into the fiber mesh 23 through the water seepage holes 22 on the side wall of the culture cylinder 21, so as to supply water to the plant seeds. The driving device drives the main shaft 13 and the culture cylinder 21 to rotate. During the rotation of the culture cylinder 21, the outer wall of the culture cylinder 21 will periodically contact the friction strip 12. Under the action of the friction strip 12, the culture cylinder 21 will rotate a certain angle, so that the plant seedlings on the fiber mesh 23 on the outer wall of the culture cylinder 21 can receive light more evenly. Since the volume of a single device of this device is small and the height is low, multiple devices can be stacked to increase the planting density and reduce the floor area. This device can not only be used for the batch planting of micro-landscape plants, but also be used for the research on the growth and reproduction of different plants in different growth environments. Among them, the fiber mesh 23 is mainly a sheet-like structure formed by weaving natural fibers or artificial fibers into a mesh structure and filling stone grains, humus soil, wood chips, soil, etc. in the mesh structure. After burying the plant seeds in the fiber mesh 23, it can be wound around the culture cylinder 21 and fixed. After cultivation, it can be directly removed. After removal, the growth state of the plants on the fiber mesh 23 can be analyzed and detected, or it can be directly laid on the place to be decorated. It should be noted that the friction strip 12 can be a soft rubber strip, which can not only better push the culture cylinder 21 to rotate, but also will not cause large-amplitude vibration of the device.

[0032] In this embodiment, a plurality of annular partitions 24 are provided on the outer wall of the culture cylinder 21, and the plurality of partitions 24 are evenly distributed along the axis of the culture cylinder 21; the plurality of partitions 24 divide the outer wall of the culture cylinder 21 into a plurality of culture areas, and a fiber mesh 23 is wound in each culture area. Specifically, the partition 24 can divide the culture cylinder 21 into different culture areas, so that different plants can be cultured in each culture area, and the growth and reproduction of different plants in the same growth environment can be observed.

[0033] In this embodiment, the height of the outer side of the partition 24 is higher than the height of its inner side. Specifically, this can prevent the water in the fiber mesh 23 from flowing into the next fiber mesh 23.

[0034] In this embodiment, the culture cylinder 21 is a conical structure with a larger upper part and a smaller lower part. The culture device 20 further includes a hollow outer cylinder 27 disposed inside the culture cylinder 21, a hollow inner cylinder 28 fixedly disposed inside the outer cylinder 27, a water inlet pipe 29 disposed at the upper end of the outer cylinder 27, a drain pipe 210 disposed at the lower end of the outer cylinder 27, a drain hole opened on the side wall of the outer cylinder 27, and a sponge layer 211 attached to the outer wall of the outer cylinder 27; the inner cylinder 28 is a closed structure, a gap is provided between the outer cylinder 27 and the inner cylinder 28, the water inlet pipe 29 is connected to the water supply device 30, and the sponge layer 211 is attached to the inner wall of the culture cylinder 21. Specifically, the water supply device 30 sends water into the gap between the outer cylinder 27 and the inner cylinder 28, and then flows into the sponge layer 211 through the drain hole on the outer cylinder 27, flows into the water seepage hole 22 through the sponge layer 211, and finally flows into the fiber mesh 23. In this way, on the premise of more effectively controlling the water flow rate, each fiber mesh 23 can fully absorb water.

[0035] In this embodiment, the water supply device 30 includes a water storage tank 31 disposed at the upper end of the main shaft 13, a plurality of water storage tanks 34, a water supply pipe 37 vertically disposed at the lower end of the water storage tank 34, a conduit 32 for connecting the water storage tank 34 and the water storage tank 31, a water pump 33 disposed on the conduit 32, a medicine tank 35 disposed above the water storage tank 34, a connecting pipe 36 for connecting the medicine tank 35 and the water storage tank 34, and a valve disposed on the connecting pipe 36; one water storage tank 34 is disposed directly above one culture cylinder 21, the water supply pipe 37 is rotatably disposed in the water inlet pipe 29, the lower end of the water supply pipe 37 is disposed between the inner cylinder 28 and the outer cylinder 27, and the water storage tank 34 is connected to the first connecting rod 25. Specifically, the water supply device 30 does not supply water continuously, but supplies water intermittently. Before each start of water supply, the high-concentration nutrients or other agents in the medicine tank 35 first flow into the water storage tank 34 quantitatively through the connecting pipe 36, and then the water pump 33 pumps the water in the water storage tank 31 into the water storage tank 34. After mixing with the nutrients and agents, it is sent into the outer cylinder 27 through the water supply pipe 37. By studying the types and addition amounts of different nutrients and agents, the growth and reproduction of different plants under different nutrients can be studied.

[0036] In this embodiment, a first groove 212 is provided at the upper end of the inner cylinder 28, a water discharge hole 38 is opened on the side wall of the lower end of the water supply pipe 37, and the lower end of the water supply pipe 37 is slidably arranged in the first groove 212; a U-shaped support rod 214 is provided at the lower end of the culture cylinder 21, a vertically arranged rotating shaft 215 is provided on the support rod 214, a limiting groove 216 is provided on the upper side of the end of the second connecting rod 26 away from the main shaft 13, and the rotating shaft 215 is rotatably arranged in the limiting groove 216. A spring 218 is fixedly provided on the upper side of the support rod 214, and one end of the spring 218 away from the support rod 214 is connected to the lower end of the outer cylinder 27; when the water pump 33 is not operating, the sponge layer 211 does not contact the inner wall of the culture cylinder 21, and the water discharge hole 38 is arranged in the first groove 212; when the water pump 33 is operating, the sponge layer 211 contacts the inner wall of the culture cylinder 21, and the water discharge hole 38 is arranged above the inner cylinder 28. Specifically, as shown in the appendix Figure 6 As shown, when there is no water supply, the spring 218 pushes up the outer cylinder 27, so that the sponge layer 211 does not contact the inner wall of the culture cylinder 21, which can avoid the fiber mesh 23 from being airtight. When the water supply starts, the water is sprayed out from the water discharge hole 38 at the lower end of the water supply pipe 37 under the action of the water pump 33, generating a downward water pressure in the first groove 212, pressing the inner cylinder 28 and the outer cylinder 27 downward, so that the outer cylinder 27 moves downward, and the sponge layer 211 contacts the inner wall of the culture cylinder 21, and the water discharge hole 38 also exposes from the first groove 212 (as shown in the appendix Figure 7 As shown), at this time, the water in the water supply pipe 37 can enter the gap between the inner cylinder 28 and the outer cylinder 27 and enter the sponge through the drainage hole, finally realizing the water supply to the fiber mesh 23.

[0037] In this embodiment, the upper end of the rotating shaft 215 passes through the support rod 214 and is arranged in the drain pipe 210, a plug plate 217 is provided on the support rod 214, and the plug plate 217 is arranged directly below the drain pipe 210; there is a gap between the outer wall of the rotating shaft 215 and the inner wall of the drain pipe 210, and the diameter of the plug plate 217 is larger than the diameter of the drain pipe 210; when the sponge layer 211 contacts the inner wall of the culture cylinder 21, the lower end of the drain pipe 210 abuts against the plug plate 217. Specifically, when the water supply device 30 starts to supply water, the outer cylinder 27 moves downward, so that the lower end of the drain pipe 210 abuts against the plug plate 217. At this time, the plug plate 217 blocks the drain pipe 210, which can significantly reduce the amount of water directly discharged from the drain pipe 210 during the water supply process. After the water supply is completed, the outer cylinder 27 and the inner cylinder 28 move upward under the action of the spring 218, and the drain pipe 210 is away from the plug plate 217. At this time, the water between the inner cylinder 28 and the outer cylinder 27 is discharged through the drain pipe 210 to avoid its long-term stay.

[0038] In this embodiment, a second groove 213 is provided at the lower end of the inner cylinder 28, and the upper end of the rotating shaft 215 is arranged in the second groove 213. Specifically, inserting the rotating shaft 215 into the second groove 213 can make the rotation of the culture cylinder 21 more stable. It should be noted that the second connecting rod 26 and the main shaft 13 can be detachably connected. In this way, when installing the culture cylinder 21, the rotating shaft 215 can be first inserted into the limiting groove 216, then the water supply pipe 37 can be inserted into the water inlet pipe 29, and finally the second connecting rod 26 can be fixed on the main shaft 13.

[0039] The driving device in this embodiment includes a driven wheel 15 connected to the lower end of the main shaft 13, a motor 16 connected to the outer wall of the box body 10, a driving wheel 17 arranged on the output shaft of the motor 16, and a transmission belt 18 for connecting the driving wheel 17 and the driven wheel 15.

[0040] In this embodiment, a box door 11 is provided on the outer wall of the box body 10, a sewage pipe is provided at the lower end of the box body 10, and feet are provided at the lower end of the box body 10.

[0041] In summary, for the micro-landscape plant propagation technology research device of this embodiment, when in use, plant seeds or seedlings are buried in the fiber mesh 23, then the fiber mesh 23 is wound around the outer wall of the culture cylinder 21, and then the two ends of the culture cylinder 21 are respectively connected to the first connecting rod 25 and the second connecting rod 26. The water supply device 30 is connected to the culture cylinder 21. The water supply device 30 sends water into the interior of the culture cylinder 21 and seeps into the fiber mesh 23 through the water seepage holes 22 on the side wall of the culture cylinder 21, so as to supply water to the plant seeds. The driving device drives the main shaft 13 and the culture cylinder 21 to rotate. During the rotation of the culture cylinder 21, the outer wall of the culture cylinder 21 will periodically contact the friction strips 12. Under the action of the friction strips 12, the culture cylinder 21 will rotate a certain angle, so that the plant seedlings on the fiber mesh 23 on the outer wall of the culture cylinder 21 can receive light more evenly. Since the volume of a single device of this device is small and the height is low, multiple devices can be stacked to increase the planting density and reduce the floor area. This device can not only be used for the batch planting of micro-landscape plants, but also be used for the research on the growth and reproduction of different plants in different growth environments.
