Description

Technical Field

[0001] This utility model relates to the technical field of Gastrodia elata cultivation devices, specifically a Gastrodia elata cultivation device based on giant reed substrate. Background Technology

[0002] As a precious Chinese medicinal herb, the artificial cultivation of Gastrodia elata requires precise control of substrate humidity and symbiotic environment. Currently, most mainstream cultivation devices adopt container structure, which fixes Gastrodia elata seeds and Armillaria mellea mycelium through substrate and relies on water replenishment system to maintain growth humidity. Among them, top spray water replenishment is widely used because of its simple operation. This method sprays water directly onto the substrate surface through nozzles and then relies on gravity to penetrate to the lower layer.

[0003] Utility model patent application number: CN202320682014.0 discloses a device for preventing water accumulation in Gastrodia elata cultivation, comprising: a cultivation box, in which a perforated plate is fixedly installed, and planting soil is placed on top of the perforated plate, wherein Gastrodia elata is planted in the planting soil; and a water replenishment component, which is installed on the cultivation box.

[0004] The aforementioned patent uses a spray nozzle to spray water onto the substrate. However, in actual use, water tends to accumulate in the upper substrate due to osmotic resistance, resulting in long-term water accumulation in the upper substrate. The Gastrodia elata tubers near the water source are prone to rotting due to lack of oxygen. Meanwhile, the middle substrate is blocked by the water accumulation in the upper layer, resulting in insufficient water penetration. The lower substrate remains dry due to low gravity penetration efficiency, creating a layered difference of "water accumulation in the upper layer, insufficient moisture in the middle layer, and dryness in the lower layer." Ultimately, this leads to uneven development of Gastrodia elata tubers and poor yield and quality stability. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a giant reed substrate-based Gastrodia elata cultivation device to solve the problems mentioned in the background section. This invention features a novel structure, incorporating a ceramic capillary tube, an absorbent sponge, a water replenishment mechanism, and a reflux structure. With the assistance of the absorbent sponge, the ceramic capillary tube continuously and evenly delivers water to the giant reed substrate, preventing localized water shortages. The water replenishment mechanism senses water level changes via a float and automatically turns on or off the water replenishment, ensuring a constant supply of water within the bottom shell. The reflux structure recovers excess water from the cultivation shell back to the bottom shell, preventing water accumulation in the substrate. This provides a stable and suitable humidity environment for Gastrodia elata, ensuring its normal growth.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a giant reed substrate gastrodia elata cultivation device, comprising a bottom shell, a cultivation shell fixedly connected to the upper side of the bottom shell, a giant reed substrate disposed inside the cultivation shell on the upper side of the bottom shell, a water replenishment mechanism disposed inside the bottom shell, an absorbent sponge installed on one side inside the bottom shell, multiple ceramic capillaries arranged in a matrix on the upper side of the bottom shell, an arc-shaped plate fixedly connected to the upper side of the inner wall of the cultivation shell, multiple micro-holes opened in a matrix on the upper side of the arc-shaped plate, and a reflux pipe fixedly connected to the lower side of the arc-shaped plate.

[0007] Furthermore, the lower end of the reflux pipe extends into the interior of the bottom shell, and the lower end of the ceramic capillary extends into the interior of the bottom shell and is inserted into the water-absorbing sponge, and the lower end of the ceramic capillary is tapered.

[0008] Furthermore, the water replenishment mechanism includes a support frame fixedly connected to one side of the inner wall of the bottom shell. The inner wall of the support frame is rotatably fitted with a rotating shaft. A connecting rod is fixedly connected to the rotating shaft. A float ball is fixedly connected to the lower end of the connecting rod. A water replenishment tank is installed on the upper side of the bottom shell. A connecting elbow is fixedly connected to one side of the water replenishment tank. A ball valve shell is fixedly connected to the lower end of the connecting elbow inside the bottom shell. A valve core is rotatably fitted to the inner wall of the ball valve shell. A limit block is fixedly connected to the upper side of the inner wall of the support frame.

[0009] Furthermore, one end of the rotating shaft extends to one side of the rotating shaft and is fixedly connected to one end of the valve core, and the connecting rod cooperates with the lower side of the limiting block.

[0010] Furthermore, a partition is fixedly connected to the inner wall of the bottom shell, and a plurality of connection holes are provided on one side of the partition.

[0011] Furthermore, each of the ceramic capillaries is equipped with a filter screen cover at its upper end.

[0012] Furthermore, a rotating door is rotatably fitted on one side of the culture shell, an observation window is installed on one side of the rotating door, and a light shield that cooperates with the observation window is rotatably fitted on one side of the rotating door.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model, by setting up a ceramic capillary tube, a water-absorbing sponge, a water replenishment mechanism, and a reflux structure, allows the ceramic capillary tube, with the assistance of the water-absorbing sponge, to continuously and evenly deliver water to the giant Napier grass substrate, avoiding localized water shortage in the substrate. The water replenishment mechanism senses changes in water level through a float ball and automatically turns on or off the water replenishment, ensuring that there is always sufficient water available for delivery in the bottom shell. The reflux structure can recover excess water in the culture shell back to the bottom shell, preventing water accumulation in the substrate, thereby providing a stable and suitable humidity environment for Gastrodia elata and ensuring its normal growth.

[0015] 2. By setting up partitions and connecting holes, the present invention divides the interior of the bottom shell into different areas, and the connecting holes allow water to flow between the areas, so that the water level in the bottom shell is kept consistent. This avoids the water delivery effect of the ceramic capillary due to insufficient water in some areas, further improving the uniformity of water supply and providing a more stable foundation for the growth of Gastrodia elata.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please refer to Figures 1 to 5This utility model provides a technical solution: a Gastrodia elata cultivation device using giant reed substrate, comprising a bottom shell 1, a cultivation shell 2 fixedly connected to the upper side of the bottom shell 1, a giant reed substrate 3 disposed inside the cultivation shell 2 on the upper side of the bottom shell 1, a water replenishment mechanism 4 disposed inside the bottom shell 1, an absorbent sponge 5 installed on one side inside the bottom shell 1, multiple ceramic capillaries 6 arranged in a matrix on the upper side of the bottom shell 1, an arc-shaped plate 7 fixedly connected to the upper side of the inner wall of the cultivation shell 2, multiple micro-holes 8 being opened in a matrix on the upper side of the arc-shaped plate 7, and a return pipe 9 fixedly connected to the lower side of the arc-shaped plate 7. The lower end of the return pipe 9 extends into the interior of the bottom shell 1, and the lower end of the ceramic capillaries 6 extends into the interior of the bottom shell 1 and is inserted into the absorbent sponge 5, and the lower end of the ceramic capillaries 6 is conical. Giant Napier grass substrate 3 is laid inside the culture shell 2 on the upper side of the bottom shell 1, providing a foundation for the growth of Gastrodia elata. Water in the bottom shell 1 is transported upward to the giant Napier grass substrate 3 through ceramic capillary tubes 6 (the lower end of which is inserted into the water-absorbing sponge 5, and its conical design enhances the water absorption effect) to meet the water requirements for the growth of Gastrodia elata. Excess water in the culture shell 2 will permeate to the arc-shaped plate 7, and after being collected through the micropores 8, it will flow back into the bottom shell 1 through the return pipe 9 to achieve recycling. The ceramic capillary tube 6, with its own characteristics and in cooperation with the water-absorbing sponge 5, can stably supply water to the giant Napier grass substrate 3, ensuring that the substrate humidity is suitable. The return structure composed of arc plate 7, micropores 8 and return pipe 9 can prevent water from accumulating in the culture shell 2, and at the same time realize water recovery and save water resources.

[0024] In this embodiment, the water replenishment mechanism 4 includes a support frame 41 fixedly connected to one side of the inner wall of the bottom shell 1. A rotating shaft 42 is rotatably fitted to the inner wall of the support frame 41. A connecting rod 43 is fixedly connected to the rotating shaft 42. A float ball 44 is fixedly connected to the lower end of the connecting rod 43. A water replenishment tank 45 is installed on the upper side of the bottom shell 1. A connecting elbow 46 is fixedly connected to one side of the water replenishment tank 45. The lower end of the connecting elbow 46 extends into the interior of the bottom shell 1 and is fixedly connected to a ball valve housing 47. A valve core 48 is rotatably fitted to the inner wall of the ball valve housing 47. A limit block 49 is fixedly connected to the upper side of the inner wall of the support frame 41. One end of the rotating shaft 42 extends to one side of the rotating shaft 42 and is fixedly connected to one end of the valve core 48. The connecting rod 43 cooperates with the lower side of the limit block 49. When the water level in the bottom shell 1 drops, the float 44 drops with the water level, driving the rotating shaft 42 to rotate on the support frame 41 via the connecting rod 43. The rotating shaft 42 then drives the valve core 48 to rotate within the ball valve housing 47, allowing water from the water supply tank 45 to flow into the bottom shell 1 through the connecting bend 46 and the ball valve housing 47. When the water level rises, the float 44 rises, causing the relevant components to reset, the valve core 48 to close, and water supply to stop. The connecting rod 43 will cooperate with the limit block 49 to limit excessive rotation of the components. The water supply mechanism 4 senses changes in water level through the float 44 and automatically controls whether to supply water, thus achieving automatic adjustment of the water level in the bottom shell 1. The limit block 49 can prevent excessive rotation of the components, ensuring the stable operation of the water supply mechanism 4 and ensuring that there is always enough water in the bottom shell 1 for the ceramic capillary tube 6 to deliver.

[0025] In this embodiment, a partition 10 is fixedly connected to the inner wall of the bottom shell 1, and multiple connection holes 11 are provided on one side of the partition 10. A filter screen cover 12 is installed at the upper end of each of the multiple ceramic capillary tubes 6. A rotating door 13 is rotatably fitted on one side of the culture shell 2, and an observation window 14 is installed on one side of the rotating door 13. A light-shielding plate 15, which cooperates with the observation window 14, is rotatably fitted on one side of the rotating door 13. The partition 10 divides the interior of the bottom shell 1, and water can flow through the connection holes 11 on both sides of the partition 10. The filter screen cover 12 on the ceramic capillary tubes 6 can prevent the giant Napier grass substrate 3 from entering the tube and causing blockage. The culture shell 2 can be opened for operation through the rotating door 13. The observation window 14 facilitates observation of the growth of Gastrodia elata, and rotating the light-shielding plate 15 can adjust the light-shielding degree of the observation window 14. The partition 10 and the connecting hole 11 make the water distribution in the bottom shell 1 more uniform, the filter cover 12 prevents the ceramic capillary tube 6 from being blocked and ensures smooth water delivery, the rotating door 13 facilitates the management of the inside of the culture shell 2, and the observation window 14 and the light shield 15 can meet the needs of observation and light regulation without affecting the growth of Gastrodia elata.

[0026] When using the device, the giant reed substrate 3 provides a growth environment for Gastrodia elata. With the assistance of the water-absorbing sponge 5, the water in the bottom shell 1 is transported to the giant reed substrate 3 through the ceramic capillary tube 6 to ensure the water supply for Gastrodia elata growth. Excess water is collected through the micro-holes 8 of the arc plate 7 and flows back to the bottom shell 1 through the return pipe 9 for recycling. When water is replenished, the water level in the bottom shell 1 drops, causing the float 44 to fall. This causes the valve core 48 to rotate through the connecting rod 43 and the rotating shaft 42. Water from the water replenishment tank 45 enters the bottom shell 1 through the connecting bend 46 and the ball valve shell 47. When the water level rises, the float 44 floats up, the valve core 48 resets, and the water replenishment is closed. The limit block 49 restricts excessive rotation of the components. The partition 10 and the connecting hole 11 ensure even distribution of water in the bottom shell 1. The filter cover 12 prevents the ceramic capillary tube 6 from clogging. The rotating door 13 facilitates operation. The observation window 14 and the light shield 15 facilitate observation and adjustment of light. The entire device achieves stable water supply, water circulation, and convenient management for the growth of Gastrodia elata.
