Description

Technical Field

[0001] The present invention relates to the technical field of drip irrigation devices, and more specifically, to an irrigation device for Chinese herbal medicine planting. Background Art

[0002] In the Chinese herbal medicine planting industry, efficient and precise irrigation is crucial for ensuring the healthy growth of Chinese herbal medicines, improving yield and quality. However, the current irrigation devices and technologies have a series of significant problems, seriously restricting the modern development of Chinese herbal medicine planting.

[0003] Regarding the currently common drip irrigation systems, most are only equipped with a single drip head and cannot be flexibly adjusted according to the differences in evaporation amounts in the morning and evening in the Chinese herbal medicine planting environment. During the day, with strong sunlight and high temperature, the water evaporation is fast, and a larger drip irrigation amount is required to meet the water demand of Chinese herbal medicines. At night, as the temperature drops and the evaporation amount decreases, an excessive drip irrigation amount may lead to too high soil humidity, affecting root respiration and even causing diseases. A single drip head is difficult to adapt to such different irrigation requirements caused by time changes, greatly reducing the irrigation effect and unable to provide the most suitable water conditions for the growth of Chinese herbal medicines.

[0004] In addition, during the process of Chinese herbal medicine planting, in order to meet the nutritional requirements at different growth stages, irrigation liquids with different fertilizer-water ratios are often needed. However, after long-term use of the existing drip irrigation pipes, due to the characteristics of the fertilizer-water components, sediments are extremely likely to be generated inside the pipes. Traditional drip irrigation pipes usually do not have a design that is convenient for observing the internal situation. Only when the drip irrigation stops and irrigation abnormalities are found can the staff possibly notice the problem of pipe blockage. This lagging discovery method may cause the growth of some Chinese herbal medicines to be severely affected due to long-term water shortage or uneven irrigation, thereby affecting the overall yield and quality.

[0005] At the same time, after the drip head is in contact with the fertilizer-water for a long time, blockage will occur inside due to the crystallization of the fertilizer-water. Once the drip head is blocked, the uniformity of the entire irrigation system will be damaged, resulting in some areas not being fully irrigated. Moreover, since the drip head is usually relatively small, it is difficult to operate to clean the blockage, not only consuming a large amount of manpower and time, but also possibly damaging the drip head due to improper cleaning, increasing the equipment maintenance cost.

[0006] In summary, the existing irrigation devices for Chinese herbal medicine planting have serious deficiencies in terms of the adaptability of the drip head, the convenience of observing the pipeline, and the anti-blockage of the drip head. These problems not only reduce the irrigation efficiency and effect, increase the labor cost and maintenance cost, but also have a negative impact on the yield and quality of Chinese herbal medicines. Therefore, it is urgent and important to develop a new type of irrigation device that can solve the above problems for promoting the sustainable development of the Chinese herbal medicine planting industry. Summary of the Invention

[0007] The object of the present invention is to provide an irrigation device for Chinese herbal medicine planting to solve the problems raised in the above-mentioned background technology.

[0008] An irrigation device for Chinese herbal medicine planting includes a liquid medicine mixing tank. A cleaning tank is arranged on the side of the liquid medicine mixing tank. The liquid medicine mixing tank is connected to a first liquid pump through a hose. The cleaning tank and a second liquid pump are connected through a hose. The liquid outlet ends of the second liquid pump and the first liquid pump are fixedly connected to a mixing pipe. A main control box is arranged on the front side of the first liquid pump. The side of the cleaning tank is connected to a pair of circulating water pumps through a hose; A number of drip irrigation pipes are distributed on both sides of the mixing pipe. A filter cylinder is arranged at the intersection position of the mixing pipe and the drip irrigation pipes. A filter detection device is arranged inside the drip irrigation pipes. A number of drip irrigation outer shells are equidistantly arranged at the lower end of the drip irrigation pipes. A liquid interface is fixedly installed in the upper middle part of the drip irrigation outer shells. A flushing pipe is arranged between multiple drip irrigation outer shells. A first drip irrigation head is slidably arranged on one side of the lower side of the inner cavity of the drip irrigation outer shell. A second drip irrigation head is slidably arranged on the other side of the lower side of the inner cavity of the drip irrigation outer shell. A pair of confluence boxes are fixedly installed on the top wall of the inner cavity of the drip irrigation outer shell. A guiding pipe is fixedly installed on the lower side of the inner cavity of the confluence box. Sealing members are fixedly installed at the upper ends of the first drip irrigation head and the second drip irrigation head. A fertilizer liquid pipe is fixedly installed above the opposite sides of the first drip irrigation head and the second drip irrigation head.

[0009] Further, both the liquid medicine mixing tank and the cleaning tank are arranged above the mounting frame. A sealing cover body is rotatably arranged at the upper end of the filter cylinder. A drain cover is threadedly arranged at the upper end of the drip irrigation pipe.

[0010] By adopting the above technical solution, operators can fill different liquids inside the liquid medicine mixing tank and the cleaning tank to meet the daily irrigation requirements. When fertilizer deposition occurs at the end of the pipeline, the drain cover can be rotated and opened to discharge the materials at the end of the drip irrigation pipe.

[0011] Further, a storage battery is fixedly installed on the side of the main control box, and a solar panel is fixedly installed on the side of the storage battery.

[0012] By adopting the above technical solution, the solar panel can continuously supply power to the storage battery on sunny days, so as to provide energy for the internal electrical equipment and save electricity.

[0013] Further, the drip irrigation outer shells are connected through the flushing pipe. The water outlets of the two circulating water pumps are respectively connected to an inlet hose and an outlet hose. The circulating water pumps and the flushing pipe form a circulating water flow circuit.

[0014] By adopting the above technical solution, the water inlet pipe is connected to the drip irrigation outer casing in the corresponding direction through a multi-way joint along the mixing pipe on the lower side of each drip irrigation pipe, and then is connected to the water outlet hose at the top of the drip irrigation pipe, so that the water body can be circulated and diluted inside the cleaning tank.

[0015] Further, a fixed mounting seat is fixedly installed at the position of the drip irrigation pipe on the upper side of the mixing pipe. A connecting seat is fixedly installed on the side of the fixed mounting seat by bolts. The upper end of the connecting seat is fixedly installed with a drip irrigation pipe, and an observation groove is formed on the front side of the drip irrigation pipe.

[0016] By adopting the above technical solution, the connecting seat can be removed so that the entire drip irrigation pipe can be picked up and replaced, which is convenient for cleaning and maintenance. At the same time, the operator can directly observe the inside through the observation groove to judge whether there is deposition inside the mixing pipe.

[0017] Further, the filtering and detecting device includes a connecting pipe fixedly installed at the bottom of the drip irrigation pipe. A detecting circulation pump is fixedly installed on the upper side of the connecting pipe. A liquid inlet pipe is fixedly installed on one side of the lower end of the detecting circulation pump, and a liquid outlet pipe is fixedly installed on the other side of the lower end of the detecting circulation pump. A circulation pipe is fixedly installed on one side of the upper end of the detecting circulation pump. A stabilizing column is arranged in the middle of the filtering cylinder. Three sub-filter plates are equidistantly fixedly installed on the outer side of the middle of the stabilizing column. A sub-filter screen is fixedly installed in the middle of the sub-filter plate. A connecting hole is fixedly installed at the position of the sub-filter screen where the circulation pipe is located. A wireless control device is fixedly installed at the upper rear end of the drip irrigation pipe. A water quality sensor and a wireless sensor are arranged inside the wireless control device.

[0018] By adopting the above technical solution, the irrigated water and fertilizer will be pumped into the top of the filtering cylinder by the detecting circulation pump from the position of the liquid inlet pipe. Then the water and fertilizer will flow downward through the sub-filter plates in turn until they are discharged from the position of the liquid inlet pipe. If the concentration of the pipeline fertilizer liquid deposits and precipitates, the operator can observe the internal state of the sub-filter screen from the observation groove, so as to judge whether it is necessary to clean the mixing pipe and avoid blockage.

[0019] Further, one end of the flushing pipe connected to the drip irrigation outer casing is fixedly connected to the side of the guiding pipe. The sealing member is a "C"-shaped member. A liquid outlet is formed on the upper side of the guiding pipe. A pair of backwashing grooves are fixedly installed on the lower side of the inner cavity of the drip irrigation outer casing. One side of one of the confluence boxes communicates with the rear side of the opposite backwashing groove. A reflux member is arranged on the lower side of the liquid interface. Both ends of the reflux member are fixedly connected to the flushing pipe.

[0020] By adopting the above technical solution, the first drip irrigation head can horizontally move inside the guiding pipe through the seal. When liquid is injected into the inside of the guiding pipe on the same side of the side flushing pipe box, the pressure will push the seal to move, aligning the first drip irrigation head on the same side with the liquid dripping port. At this time, the fertilizer liquid pipe on the upper side of the first drip irrigation head will be aligned with the liquid interface, and corresponding drip irrigation operations can be carried out. At the same time, as it moves towards the side of the seal, the liquid in the flushing pipe enters the inside of the confluence box through the liquid outlet, and then the liquid will enter below the second drip irrigation head inside the counter flushing groove on the opposite side for back flushing. At this time, the liquid will continuously exert pressure on the second drip irrigation head, and the upper end of the second drip irrigation head is connected to the through groove opened on the lower side of the reflux part, and the liquid will flow back into the flushing pipe on the other side, and the crystallization inside the corresponding second drip irrigation head will be diluted and removed.

[0021] Further, a main control device is arranged inside the main control box, and the main control device can control the start and stop of the circulating water pump and the second liquid pump. Liquid level sensors are arranged inside the liquid medicine mixing box and the cleaning box. The drip irrigation outer casing and the drip irrigation pipe form an irrigation module, and the cleaning box, the flushing pipe and the circulating water pump form a back flushing module.

[0022] By adopting the above technical solution, the liquid level sensor, the water quality sensor and the wireless sensor are all electrically connected to the main control. Through the liquid level sensor, the amount of water inside the liquid medicine mixing box and the cleaning box can be observed in real time. Through the water quality sensor, whether the concentration of the fertilizer water has changed too much due to pipeline sedimentation can be finely detected.

[0023] Compared with the prior art, the advantages of the present invention are as follows: 1. In the present invention, by arranging the structure of the first drip irrigation head and the second drip irrigation head, different drip irrigation heads can be used for suitable irrigation of Chinese herbal medicines in different light periods, which can more precisely meet the irrigation requirements of plants in different time periods, and enable the Chinese herbal medicines to maintain an appropriate soil moisture level.

[0024] 2. In the present invention, by arranging the structure of the drip irrigation pipe, the planting personnel can more carefully observe the deposition state inside the pipeline through the drip irrigation pipe. At the same time, a water quality sensor is arranged inside to enable the planting personnel to have a more detailed understanding of the situation inside the pipeline, reducing the blockage of the drip heads.

[0025] 3. In the present invention, by arranging the structure of the drip irrigation outer casing, during the process of switching the drip heads, the unused drip heads on the other side can be flushed with water. Since long-term exposure to high-concentration fertilizer water will cause crystallization, which will eventually block the drip heads, this structure can avoid crystal accumulation and extend the overall service life.

A water quality sensor and a wireless sensor are set inside the wireless control 33. The irrigation water and fertilizer will be detected from the position of the liquid inlet pipe 17 and drawn into the top of the filter cartridge 3 by the circulation pump 19. After that, the water and fertilizer will pass through the filter plate 20 in sequence and flow downward until they are discharged from the position of the liquid inlet pipe 17. If the concentration of the fertilizer liquid in the pipeline is precipitated, the operator can observe the internal state of the filter screen 2001 from the observation tank 201 to determine whether the mixing pipe 15 needs to be cleaned to avoid blockage. One end of the flushing pipe 25 connected to the drip irrigation outer shell 4 is fixedly connected to the side of the guide tube 30. The seal 23 is a "C"-shaped component. A liquid outlet 3001 is opened on the upper side of the guide tube 30. A pair of backwash grooves 27 are fixedly installed on the lower side of the inner cavity of the drip irrigation outer shell 4. One side of one junction box 31 is connected to the rear side of the backwash groove 27 on the opposite side. A reflux member 3201 is provided on the lower side of the liquid interface 32. Both ends of the reflux member 3201 are fixedly connected to the flushing pipe 25. The first drip irrigation head 26 can move horizontally inside the guide tube 30 through the seal 23. When the side flushing pipe 25 injects liquid into the guide tube 30 on the same side, the pressure will push the seal 23 to move. Align the first drip irrigation head 26 on the same side with the dripping port 29. At this time, the fertilizer liquid pipe 28 on the upper side of the first drip irrigation head 26 will be aligned with the liquid interface 32, and the corresponding drip irrigation operation can be carried out. At the same time, it moves toward the side of the sealing member 23. The liquid in the flushing pipe 25 enters the interior of the manifold box 31 through the liquid outlet 3001. The liquid then enters the lower part of the second drip irrigation head 2601 in the backwash groove 27 on the opposite side for backwashing. At this time, the liquid will continuously apply pressure to the second drip irrigation head 2601. The upper end of the second drip irrigation head 2601 is connected to the lower side of the return member 3201 through a groove. The liquid will flow back into the flushing pipe 25 on the other side, and the crystals inside the corresponding second drip irrigation head 2601 will be diluted and removed. Inside the main control box 13, there is a main control device which can control the start and stop of the circulating water pump 14 and the second liquid pump 10. Inside the liquid medicine mixing tank 7 and the cleaning tank 9, there are liquid level sensors. The drip irrigation outer casing 4 and the drip irrigation pipe 2 form an irrigation module. The cleaning tank 9, the flushing pipe 25 and the circulating water pump 14 form a backwashing module. The liquid level sensor, the water quality sensor and the wireless sensor are all electrically connected to the main control. Through the liquid level sensor, the amount of water inside the liquid medicine mixing tank 7 and the cleaning tank 9 can be observed in real time. Through the water quality sensor, it can be finely detected whether the concentration of the fertilizer solution has changed too much due to pipeline sedimentation.

[0030] Working principle of the present invention: The planter can fill the configured fertilizer solution inside the liquid medicine mixing tank 7 and fill the cleaning tank 9 with clean water. The main control box 13 can control the first liquid pump 8 and the second liquid pump 10 to mix the liquids inside the liquid medicine mixing tank 7 and the cleaning tank 9 to achieve a proper ratio. The water outlets of the two circulating water pumps 14 are respectively connected to the inlet hose and the outlet hose. The circulating water pump 14 and the flushing pipe 25 form a circulating water flow path. The inlet pipe passes along the mixing pipe 15 and is respectively connected to the drip irrigation outer casing 4 in the corresponding direction through a multi-way joint under the lower side of each drip irrigation pipe 2, and then is connected to the outlet hose at the top of the drip irrigation pipe 2. The water body can be circulated and diluted inside the cleaning tank 9. The operator can set the start and circulation direction of the pair of circulating water pumps 14 inside the main control box 13 according to the local weather as needed. When the circulating water pump 14 is in reverse circulation, the liquid inside the cleaning tank 9 is pumped into the confluence box 31 above the first drip irrigation head 26 through the flushing pipe 25. The first drip irrigation head 26 can horizontally move inside the guiding pipe 30 through the seal 23. When the side flushing pipe 25 injects liquid into the guiding pipe 30 on the same side, the pressure will push the seal 23 to move, so that the first drip irrigation head 26 on the same side is aligned with the liquid dripping port 29. At this time, the fertilizer liquid pipe 28 above the first drip irrigation head 26 will be aligned with the liquid interface 32, and the corresponding drip irrigation operation can be carried out. At the same time, moving towards the side of the seal 23, the liquid of the flushing pipe 25 enters the inside of the confluence box 31 through the liquid outlet 3001, and then the liquid enters below the second drip irrigation head 2601 inside the counter side backwashing groove 27 for backwashing. At this time, the liquid will continuously press on the second drip irrigation head 2601, and the upper end of the second drip irrigation head 2601 is connected to the through groove opened on the lower side of the reflux member 3201, and the liquid will flow back into the flushing pipe 25 on the other side. At this time, the first drip irrigation head 26 is aligned with the lower liquid dripping port 29, and the liquid inside the drip irrigation pipe 2 passes through the liquid interface 32 and passes through the fertilizer liquid pipe 28 into the first drip irrigation head 26, and the fertilizer liquid will drip downward from the liquid dripping port 29, and the crystals inside the corresponding second drip irrigation head 2601 will be diluted and removed; When the circulating water pump 14 circulates in the reverse direction, the liquid in its cleaning tank 9 will enter the liquid outlet 3001 from the flushing pipe 25 near the second drip head 2601, so that the second drip head 2601 can be pushed to the position of the liquid dripping port 29. Repeating the above process, the drip head under the first drip head 26 will be inside the corresponding backwashing groove 27. At this time, the second drip head 2601 is communicated with the liquid interface 32 through the upper side fertilizer liquid pipe 28 and performs drip irrigation operations. The drip head on the lower side of the backwashing groove 27 will be flushed and cleaned by the liquid inside the cleaning tank 9, which can more precisely meet the irrigation requirements of plants at different time periods. And this structure can avoid crystal accumulation and extend the overall service life. After the device has been used for a period of time, due to various factors such as different temperatures and preparation times inside the fertilizer liquid, condensation may occur in the drip irrigation pipe 2. The detection circulating pump 19 will regularly pump the liquid inside the drip irrigation pipe 2 from the circulating pipe 22 to the top of the filter cylinder 3. The liquid passes through the sub-filter screen 2001 downward and is discharged through the liquid outlet pipe 18 on the lower side of the detection circulating pump 19. The generated sediment residues will all remain inside the filter cylinder 3. As more and more solids remain in the filter cylinder 3, the internal detection device gives an alarm. The planting personnel can observe the deposition state inside the pipeline more carefully through the drip irrigation pipe 2, which is convenient for cleaning the irrigation device immediately and reducing the clogging of the drip heads. Among them, the operator needs to regularly replace the water body inside the cleaning tank 9 to maintain the self-cleaning effect.

Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
