Description

Technical Field

[0001] This invention belongs to the technical field of medicinal herb cultivation devices, specifically, it relates to a tuberous medicinal herb cultivation device and cultivation method. Background Technology

[0002] The cultivation of tuberous Chinese medicinal herbs (such as Gastrodia elata and Pinellia ternata) has strict requirements for soil moisture conditions. Their tubers mostly grow at a specific depth underground (usually 10-30 cm). Insufficient water will affect the tuber enlargement, while excessive water will easily cause rot.

[0003] In traditional cultivation, it is necessary to maintain the soil moisture balance through proper watering, while taking into account the different needs of stem and leaf growth and tuber development, in order to ensure the quality and yield of medicinal materials. Therefore, water management is one of the core aspects of this type of Chinese medicinal material cultivation.

[0004] In the current cultivation of tuberous Chinese medicinal herbs, traditional watering methods mostly rely on surface irrigation or manual spraying, which makes it difficult to accurately reach the tuber growth area. This can easily lead to a situation where the surface is moist but the deeper layers are dry or the whole plant is too wet, which is not conducive to the growth of Chinese medicinal herbs and has certain shortcomings. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a medicinal herb cultivation device that can overcome or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is: a tuberous Chinese medicinal herb cultivation device, comprising: A lifting platform, wherein multiple sets of motors are fixedly connected at equal intervals at the bottom of the lifting platform, and multiple sets of telescopic rods are fixedly connected to the lifting platform; A rotating disk is fixedly connected to the output end of the motor; Multiple sets of long rods are rotatably connected to the rotating disk at equal intervals. In their natural state, the long rods are perpendicular to the ground. When the rotating disk rotates, the long rods will be parallel to the ground due to the influence of centrifugal force. A humidity sensor is mounted on the end of the long rod furthest from the rotating disk; Multiple sets of atomizing nozzles are installed at equal intervals on the long rod, and the atomizing nozzles are used to spray atomized nutrient solution; The lifting plate is installed above the Chinese herbal medicine cultivation container, and the Chinese herbal medicine is located between two adjacent sets of rotating discs. When watering daily, the motor rotates the long rod and makes it horizontal to the ground. Then, the atomized nutrient solution is sprayed out through the atomizing nozzle to spray the Chinese herbal medicine with nutrient solution. By lowering the lifting plate, a long rod perpendicular to the ground can be inserted into the soil. Then, a humidity sensor can detect the humidity in the soil near the roots and stems of Chinese medicinal herbs. If watering is needed, nutrient solution is sprayed through atomizing nozzles to water the soil separately. Afterward, the lifting plate is reset.

[0007] Furthermore, the rotating disk is provided with multiple sets of empty slots at equal intervals, and the long rod is rotatably connected in the empty slots.

[0008] Furthermore, a rotating shaft is fixedly connected to the long rod, and the rotating shaft is rotatably connected in the slot. An electromagnet is fixedly connected inside the rotating disk, and the electromagnet is in contact with the rotating shaft, so that the rotating shaft can be fixed by the electromagnet.

[0009] Furthermore, the long rod is arranged in an inclined rhomboid shape, and the atomizing nozzle is installed on the leeward side of the long rod after it has been rotated.

[0010] Furthermore, a sliding sleeve is slidably connected to the long rod. The sliding sleeve is used to move by centrifugal force after the long rod rotates, thereby cleaning the surface of the long rod.

[0011] Furthermore, an insertion block is fixedly connected to the end of the long rod away from the rotating disk, and the insertion block is larger than the long rod.

[0012] Furthermore, a limiting plate is fixedly connected to the bottom of the sliding sleeve. When the long rod is inserted into the soil, the sliding sleeve will move upward along the long rod under the action of the limiting plate.

[0013] Furthermore, an electromagnet is fixedly connected to one end of the long rod near the rotating shaft.

[0014] Furthermore, a rotating connector is fixedly connected to the output end of the motor, the rotating disk is fixedly connected to the rotating connector, and multiple sets of connecting pipes are connected to the rotating connector. The multiple sets of connecting pipes are connected to atomizing nozzles on multiple sets of long rods, and the connecting pipes have electronic flow valves for supplying water to the atomizing nozzles.

[0015] A method for cultivating tuberous Chinese medicinal herbs, using a cultivation device for tuberous Chinese medicinal herbs, mainly includes the following operating steps: Step 1: Plant the tuberous Chinese medicinal herbs in the cultivation box at intervals, and install the lifting plate above the cultivation box, with the Chinese medicinal herbs located between two adjacent motors; Step 2: By periodically starting the motor, the long rod rotates, generating airflow and simultaneously spraying atomized nutrient solution through the atomizing nozzle to water the Chinese medicinal herbs; Step 3: After watering, energize the electromagnet to fix the position of the long rod, and then use the telescopic rod to lower the lifting plate, so that the long rod can be inserted into the soil near the roots of the Chinese medicinal herb. Step 4: Detect soil moisture using a humidity sensor, and replenish water individually using a misting nozzle based on the moisture level. Step 5: Reset the telescopic pole, pull the long pole out of the soil, and start the motor to shake off the soil adhering to the long pole; Step 6: Repeat steps 2 to 5 to replenish water to the Chinese medicinal herbs and test the soil moisture content.

[0016] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention realizes daily watering through atomizing nozzles, providing moisture to the stems, leaves and surface soil of Chinese medicinal materials; more importantly, it can use a long rod to insert into the soil to detect deep humidity, and control the atomizing nozzles to replenish water to the soil at the root and stem based on the actual humidity data, so as to meet the water needs of different growth stages of medicinal materials, reduce water waste, and greatly facilitate the cultivation and management of tuberous Chinese medicinal materials.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] Example: Refer to Figure 1-9 A cultivation device for tuberous Chinese medicinal herbs includes: a lifting plate 102, with multiple sets of motors 2 fixedly connected at equal intervals at the bottom of the lifting plate 102, and multiple sets of telescopic rods 101 fixedly connected to the lifting plate 102; a rotating disk 4 fixedly connected to the output end of the motors 2; multiple sets of long rods 5 rotatably connected at equal intervals to the rotating disk 4. In its natural state, the long rods 5 are perpendicular to the ground, but when the rotating disk 4 rotates, the long rods 5 will become parallel to the ground due to centrifugal force; a humidity sensor 6 installed on the end of the long rod 5 away from the rotating disk 4; and multiple sets of atomizing nozzles 7 installed at equal intervals on the long rods 5 for spraying... Atomized nutrient solution; the lifting plate 102 is installed above the Chinese herbal medicine cultivation container, with the Chinese herbal medicine located between two adjacent sets of rotating discs 4. During routine watering, the motor 2 rotates the long rod 5 horizontally to the ground, and then the atomized nutrient solution is sprayed out through the atomizing nozzle 7 to spray the Chinese herbal medicine with nutrient solution; by lowering the lifting plate 102, the long rod 5 perpendicular to the ground can be inserted into the soil, and then the humidity sensor 6 detects the humidity in the soil near the roots and stems of the Chinese herbal medicine. If watering is required, the nutrient solution is sprayed out through the atomizing nozzle 7 to water the soil separately, and then the lifting plate 102 is reset.

[0021] Multiple empty slots 401 are evenly spaced on the rotating disk 4, and the long rod 5 is rotatably connected in the empty slots 401.

[0022] A rotating shaft 501 is fixedly connected to the long rod 5. The rotating shaft 501 is rotatably connected in the empty slot 401. An electromagnet 402 is fixedly connected in the rotating disk 4. The electromagnet 402 is in contact with the rotating shaft 501. The rotating shaft 501 can be fixed by the electromagnet 402.

[0023] The cross-section of the long rod 5 is rhomboid, and one pair of opposite sides of the rhombus are parallel to the length direction of the long rod 5. The atomizing nozzle 7 is installed on the leeward side face formed when the long rod 5 rotates. When the long rod 5 rotates, the rhomboid structure can cut the air through the two side faces to form an airflow, which enhances the diffusion of the atomized nutrient solution.

[0024] A sliding sleeve 8 is slidably connected to the long rod 5. The sliding sleeve 8 is used to move by centrifugal force after the long rod 5 rotates, thereby cleaning the surface of the long rod 5.

[0025] An insertion block 502 is fixedly connected to the end of the long rod 5 away from the rotating disk 4. The insertion block 502 is larger than the long rod 5.

[0026] The bottom of the sliding sleeve 8 is fixedly connected to a limiting plate 801. When the long rod 5 is inserted into the soil, the sliding sleeve 8 will move upward along the long rod 5 under the action of the limiting plate 801.

[0027] An electromagnet 2 503 is fixedly connected to one end of the long rod 5 near the rotating shaft 501.

[0028] A rotary connector 3 is fixedly connected to the output end of the motor 2. A rotating disk 4 is fixedly connected to the rotary connector 3. Multiple sets of connecting pipes 9 are connected to the rotary connector 3. The multiple sets of connecting pipes 9 are connected to the atomizing nozzles 7 on the multiple sets of long rods 5. The connecting pipes 9 have electronic flow valves inside for supplying water to the atomizing nozzles 7.

[0029] This embodiment takes the cultivation of Gastrodia elata as an example to explain the usage of the device. The tubers of Gastrodia elata usually grow 15-20 cm underground. When planting, the plant spacing is generally set at 20 cm × 30 cm. The overall operation process of the device is described in detail below.

[0030] After the device is installed, the lifting plate 102 is fixed above the Gastrodia elata planting bed by the telescopic rod 101, about 60 cm above the ground. To prevent the lifting plate 102 from squeezing the Gastrodia elata plants when it moves down, a rectangular opening is made on the lifting plate 102 corresponding to the position where the plants grow. It is not shown in the figure. The opening size is 10 cm × 8 cm to prevent scratching the plants. The motor 2 is installed at the corresponding position of the two rows of Gastrodia elata, in the gap between the openings. The long rod 5 is perpendicular to the ground in its natural state. The sliding sleeve 8 hangs down naturally due to its own weight, which will block the humidity sensor 6 and protect the humidity sensor 6.

[0031] Every morning, or when water needs to be replenished, motor 2 starts, driving the rotating disc 4 to rotate rapidly. Under the action of centrifugal force, the long rod 5 unfolds to a horizontal state around the rotating shaft 501. The atomizing nozzle 7 is connected to the nutrient solution containing trace elements through the connecting pipe 9. The nutrient solution needs to be stored in a separate tank and equipped with a water pump. The water pump is connected to the connecting pipe 9. Under the airflow generated by the rotation of the long rod 5, the nutrient solution droplets fall evenly on the stems, leaves and surface soil of Gastrodia elata. The spraying continues for 15 minutes to complete the daily water replenishment. The water pump stops, and then the speed of motor 2 decreases until it stops. The long rod 5 returns to a vertical state under the action of gravity.

[0032] In the afternoon, or after watering, the device begins deep humidity detection. First, electromagnet 402 is energized, fixing the long rod 5 in a vertical position. The telescopic rod 101 extends, causing the lifting plate 102 to move downwards. At this time, the stem of the Gastrodia elata plant passes through the opening on the lifting plate 102, avoiding contact between the lifting plate 102 and the plant, thus preventing squeezing damage. The long rod 5 is slowly inserted into the soil through the insertion block 502 at its end. During insertion, after the limiting plate 801 touches the soil surface, it pushes the sliding sleeve 8 upwards along the long rod 5 to the top, simultaneously scraping off any soil that may be attached to the surface of the long rod 5. At this point, the humidity sensor 6 is exposed and can perform normal detection. When the insertion depth reaches 18 cm, the humidity sensor 6... Located at a depth of 15-20 cm where the Gastrodia elata tubers grow, the system can detect soil moisture in real time and transmit data. If the detected moisture is lower than 65% of the field capacity, the water pump starts and the amount of liquid discharged is controlled by an electronic flow valve. When the preset amount is reached, the electronic flow valve sends a signal, the solenoid valve closes, and water replenishment stops. Meanwhile, the remaining atomizing nozzles 7 continue to replenish water to other areas that need it. The atomizing nozzles 7 spray atomized water onto the soil around the tubers. The amount of water replenishment is adjusted according to the moisture difference. After water replenishment is completed, the telescopic rod 101 retracts, pulling the long rod 5 out of the soil. The sliding sleeve 8 falls back under the action of gravity, blocking the moisture sensor 6 again and scraping off some surface soil attached to the long rod 5.

[0033] Electromagnet 2503 mainly plays a role in manual maintenance. When cleaning and maintaining the atomizing nozzle 7 and humidity sensor 6, the sensor detection effect is poor due to soil adhesion. The sliding sleeve 8 can be moved to the top, and the electromagnet 2503 can be energized in advance to attract and fix the sliding sleeve 8 to the top, preventing the sliding sleeve 8 from sagging and affecting the maintenance work.

[0034] Specifically, after insertion, the long rod 5 can be rotated for about ten seconds by motor 2 to shake off some of the attached dirt, making it easier to use.

[0035] It is important to note that after the long rod 5 is repeatedly inserted into the soil, a hole with a diameter of about 1.5 cm will be left on the surface. If this is not addressed for a long time, it will affect the soil's aeration and be detrimental to the growth of the Gastrodia elata tubers. Therefore, the hole needs to be filled every week. This can be done manually by gently filling the hole with fine soil and compacting it slightly. In addition, the lifting plate 102 is designed to move along a track parallel to the direction of the planting bed. When there is a deviation in the spacing between plants of Gastrodia elata, or when it is necessary to focus on monitoring a local area, the position of the lifting plate 102 can be adjusted by the controller to ensure that the opening is precisely aligned with the plant. The long rod 5 can also accurately correspond to the gap between the target plants, avoiding blind spots in detection or plant compression due to a fixed position, thus improving the applicability of the device in actual planting.

[0036] Throughout the entire growth cycle, the device operates fully automatically via a PLC controller. Staff can monitor soil moisture data, water replenishment, and equipment operating status in real time via a terminal APP. 120-150 days after planting during the tuber enlargement period of Gastrodia elata, the controller will automatically raise the humidity threshold to 70% of the field water holding capacity. 20 days before harvest, the threshold will be lowered to 60%, while reducing the number of spray waterings. By precisely controlling soil moisture through targeted watering, tuber maturation can be promoted.

[0037] A method for cultivating tuberous Chinese medicinal herbs, using a cultivation device for tuberous Chinese medicinal herbs, mainly includes the following operating steps: Step 1: Plant the tuberous Chinese medicinal herbs in the cultivation box at intervals, and install the lifting plate 102 above the cultivation box, with the Chinese medicinal herbs located between two adjacent motors 2; Step 2: By periodically starting the motor 2, the long rod 5 is rotated, generating airflow and spraying atomized nutrient solution through the atomizing nozzle 7 to water the Chinese medicinal materials; Step 3: After watering, the position of the long rod 5 is fixed by energizing the electromagnet 402, and then the lifting plate 102 is lowered by the telescopic rod 101, so that the long rod 5 is inserted into the soil near the root of the Chinese medicinal herb. Step 4: Detect soil moisture using humidity sensor 6, and replenish water individually using atomizing nozzle 7 based on the moisture level. Step 5: Reset telescopic pole 101, pull long pole 5 out of the soil, and start motor 2 to shake off the soil adhering to long pole 5. Step 6: Repeat steps 2 to 5 to replenish water to the Chinese medicinal herbs and test the soil moisture content.

[0038] This invention enables daily watering through the atomizing nozzle 7, providing moisture to the stems, leaves, and surface soil of medicinal herbs. More importantly, the long rod 5 can be inserted into the soil to detect deep humidity, and the atomizing nozzle 7 can be controlled to replenish water to the soil at the root and stem based on the actual humidity data, meeting the water needs of medicinal herbs at different growth stages, reducing water waste, and greatly facilitating the cultivation and management of tuberous medicinal herbs.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
