Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine planting technology, specifically a drip irrigation device for traditional Chinese medicine seedling cultivation. Background Technology

[0002] With the increasing demand for traditional Chinese medicinal materials, the cultivation and seedling industry of Chinese medicinal materials has gradually become an important branch of agriculture. By cultivating high-quality medicinal materials, the needs of the Chinese medicine and health product market can be met. Among them, Buddha's Hand is a common Chinese medicinal material and is also used as an ornamental plant.

[0003] In the process of cultivating Buddha's Hand, proper water supply is one of the key factors to ensure its healthy growth. Traditional irrigation methods involve workers using tools such as kettles and buckets to directly pour water into the soil around the roots of the Buddha's Hand. Alternatively, workers use water pumps to transport water from pools or reservoirs to drip irrigation pipes, which then provide sufficient water support for the cultivated Buddha's Hand.

[0004] Currently, manual watering suffers from drawbacks such as low efficiency, difficulty in ensuring uniformity, and high labor intensity for workers. While water pumps and drip irrigation offer high efficiency and uniformity, in actual use, the presence of impurities (such as algae, silt, suspended solids, and organic debris) in the pool or reservoir necessitates the installation of a filter screen at the inlet pipe of the water pump. This prevents impurities from entering the pump and causing wear, and also reduces the risk of pipe and dripper blockage. However, cleaning the filter screen often presents numerous inconveniences in practice. Workers cannot easily monitor the flow status of the filter screen, and if it is not cleaned in time, blockages can lead to poor water intake, reduced pump efficiency, and even malfunctions such as idling and overload, becoming a hidden danger to the system's operation. Therefore, to solve the aforementioned problems, a drip irrigation device for Chinese herbal medicine seedling cultivation is proposed. Utility Model Content

[0005] This utility model provides a drip irrigation device for Chinese herbal medicine seedling cultivation. With the setting of pressure sensor, intelligent controller and sound and light buzzer, workers can easily monitor the flow status of filter screen so as to clean the filter screen in time. With the setting of branch pipe, backwash pipe and waste discharge pipe, the filter screen can be automatically flushed. This solves the problem mentioned in the background art that workers are inconvenient to monitor the flow status of filter screen and thus inconvenient to clean the filter screen in time.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Reference Figures 1-5 A drip irrigation device for Chinese herbal medicine seedling cultivation includes a base 1 with a water pump 2 fixedly mounted on top. The water pump 2 can be a Grundfos CM5-6IC or CM10-27 model, equipped with frequency conversion function. An inlet pipe 3 is fixedly connected to the inlet end of the water pump 2. A filter screen 5, a basket filter, is inserted into the end of the inlet pipe 3 away from the water pump 2. This filter screen 5 has the advantages of large filtration area, strong dirt-holding capacity, and easy cleaning. A suction pipe 4 is fixedly connected to the inlet pipe 3 via a flange. A drain pipe is fixedly connected to the outlet end of the water pump 2. Pipe 6, the end of the drain pipe 6 away from the water pump 2 is provided with a drip irrigation assembly, and the drip irrigation assembly includes a main pipe 61 fixedly connected to one end of the drain pipe 6. Multiple sets of drip tubes 62 are fixedly connected to the main pipe 61, and drip heads are fixedly installed on the drip tubes 62, so that water can be dripped into the soil in the root area of ​​the Buddha's Hand. Here, the number of drip tubes 62 is 4 to 12 sets. This device takes 5 sets as an example. The base 1 is provided with a feedback unit, which is used to monitor the flow status of the filter screen 5. The water pump 2 is provided with a backwash unit for rinsing the filter screen 5.

[0020] Specifically, the feedback unit can monitor the pressure difference before and after the filter screen 5 in real time. If any abnormality is detected, an alarm will be triggered to remind the workers. This allows workers to easily monitor the flow status of the filter screen 5 and clean it in a timely manner, preventing clogging and ensuring efficient, safe, and reliable operation of the device. This also helps improve the drip irrigation effect on plants. Furthermore, the backwash unit facilitates automatic flushing of the filter screen 5 without disassembling it for cleaning, greatly simplifying maintenance for workers, significantly reducing maintenance time, and improving work efficiency. This makes the seedling management of Chinese medicinal herbs more convenient and efficient.

[0021] Of course, in other embodiments, the feedback unit includes an electrical box 71 fixedly connected to the base 1, and the electrical box 71 is hinged with a door. The electrical box 71 has holes and vertical slots for wiring and heat dissipation. Pressure sensors 7 are fixedly installed on both the water inlet pipe 3 and the water outlet pipe 4. The model can be WIKA-CDP100 or Kunlun Coast JWB1-50 / 100. The electrical box 71 is provided with an alarm device for use with the pressure sensor 7. The alarm device includes an intelligent controller 72 fixedly installed in the electrical box 71. The model can be Siemens SINAMICS series, Schneider Electric Altivar series or Emerson PACSystems series. A sound and light buzzer 73 is fixedly installed on the top of the electrical box 71. The model can be Mallory Sonalert-SC628 or Werma-Signalgeber814.101. The pressure sensor 7 and the sound and light buzzer 73 are both electrically connected to the intelligent controller 72.

[0022] Specifically, during use, the two pressure sensors 7 before and after the filter screen 5 can monitor the pressure difference changes in real time and transmit the data to the intelligent controller 72. When the pressure difference exceeds the preset pressure difference threshold of the intelligent controller 72 (here, the pressure difference range is 0.3MPa-0.5MPa, taking 0.3MPa as an example), the alarm mechanism of the audible and visual buzzer 73 will be triggered, which will then issue an audible and visual alarm and remind the worker to clean the filter screen 5. This allows the worker to monitor the flow status of the filter screen 5 so that the filter screen 5 can be cleaned in time, avoiding the filter screen 5 from becoming clogged and causing poor water intake, thereby ensuring the efficient, safe and reliable operation of the device and helping to improve the drip irrigation effect on plants.

[0023] The backflushing section includes a branch pipe 8, and both ends of the branch pipe 8 are fixedly connected to the inlet pipe 3 and the pumping pipe 4 respectively via quick connectors. A basket filter screen is inserted into the end of the branch pipe 8 near the pumping pipe 4 for filtering the backflushing water. Here, the quick connector is a socket connector, which allows for quick insertion and removal of the branch pipe 8 to facilitate the disassembly and assembly of the inlet pipe 3 and the pumping pipe 4. It also allows for easy maintenance of the basket filter screen. The inlet pipe 3 is connected to the drain pipe 6 via the backflushing pipe 9. A waste discharge pipe 10 is fixedly connected to the pumping pipe 4. The water pump 2 is equipped with a valve assembly for controlling the water flow direction. The valve assembly includes a first valve 81 fixedly installed on the branch pipe 8, a second valve 82 fixedly installed on both the inlet pipe 3 and the pumping pipe 4, a third valve 91 fixedly installed on the backflushing pipe 9, a fourth valve 92 fixedly installed on the drain pipe 6, and a fifth valve 101 fixedly installed on the waste discharge pipe 10.

[0024] Specifically, when in use, first open the second valve 82 and the fourth valve 92, and start the water pump 2 to discharge the water source in the pool or reservoir into the main pipe 61 through the pumping pipe 4, the inlet pipe 3 and the drain pipe 6. During this process, the impurities in the water flow can be filtered through the filter screen 5. Finally, the water is evenly dripped into the soil in the root area of ​​the Buddha's Hand through the drip pipe 62, so that the cultivated plants can obtain sufficient water support. When the worker receives the alarm, he first opens the first valve 81, the third valve 91, and the fifth valve 101. By starting the water pump 2, the water flow temporarily flows through the branch pipe 8, the drain pipe 6, and the backwash pipe 9 into the inlet pipe 3. The water flow will then carry away the impurities in the filter screen 5 and discharge them to the outside through the pumping pipe 4 and the waste discharge pipe 10. This allows for automatic rinsing of the filter screen 5 without the need to disassemble and clean it, greatly facilitating the worker's maintenance work, significantly shortening maintenance time, and improving work efficiency. This makes the seedling management of Chinese medicinal herbs more convenient and efficient.

[0025] It should be noted that, due to the large filtration area and strong dirt-holding capacity of the basket filter, the backwash function of this device will only be used when the flow of the filter 5 is reduced due to long-term drip irrigation. Under normal circumstances, this function will not be used frequently. Therefore, it can be seen that the basket filter at the port of the branch pipe 8 does not require frequent maintenance. Its maintenance frequency is much lower than the cleaning frequency of the filter 5, and it will not increase the workload of the workers.

[0026] In this utility model, when in use, first open the second valve 82 and the fourth valve 92, and start the water pump 2 to input the water source in the pool or reservoir into the main pipe 61 through the pumping pipe 4, the inlet pipe 3 and the drain pipe 6. During this process, the filter screen 5 can filter the impurities in the water flow. Finally, the water is evenly dripped into the soil in the root area of ​​the Buddha's Hand through the drip pipe 62, so that the cultivated plant can obtain sufficient water support. Furthermore, during use, the two pressure sensors 7 before and after the filter screen 5 can monitor the pressure difference changes before and after the filter screen 5 in real time and transmit the data to the intelligent controller 72. When the pressure difference exceeds the pressure difference threshold preset by the intelligent controller 72, the alarm mechanism of the audible and visual buzzer 73 will be triggered, thereby issuing an audible and visual alarm and reminding the worker to clean the filter screen 5. This makes it easier for the worker to monitor the flow status of the filter screen 5 so that the filter screen 5 can be cleaned in a timely manner. When the worker receives the alarm, he first opens the first valve 81, the third valve 91, and the fifth valve 101. By starting the water pump 2, the water flow temporarily flows through the branch pipe 8, the drain pipe 6, and the backwash pipe 9 into the inlet pipe 3. The water flow will then carry away the impurities in the filter screen 5 and discharge them to the outside through the pumping pipe 4 and the waste discharge pipe 10. This allows for automatic rinsing of the filter screen 5 without the need to disassemble and clean it, greatly facilitating the worker's maintenance work, significantly shortening maintenance time, and improving work efficiency. This makes the seedling management of Chinese medicinal herbs more convenient and efficient.
