Description

Technical Field

[0001] This utility model relates to the field of Astragalus membranaceus cultivation technology, and in particular to a temperature-sensitive water and fertilizer supply device for Astragalus membranaceus cultivation. Background Technology

[0002] Astragalus, also known as arrow astragalus or pill astragalus, is the root system of a perennial tall herbaceous plant in the legume family. It is rich in nutrients, including polysaccharides, flavonoids, saponins, amino acids, trace elements, and other bioactive substances. It not only has the health benefits of bidirectional regulation of the body's immune function, antibacterial, anti-fatigue, delaying cell aging, and enhancing the body's disease resistance, but also has the functions of tonifying qi and raising yang, consolidating the exterior and stopping sweating, detoxifying and draining pus, and promoting diuresis and reducing swelling. It is one of the most commonly used qi-tonifying drugs in clinical practice and one of the most consumed Chinese medicinal materials. The western and northern regions of the Loess Plateau are the main producing areas of astragalus. Currently, the cultivated astragalus is mainly Mongolian astragalus, and its production scale accounts for 70% to 80% of the total national astragalus production.

[0003] Astragalus seedlings are extremely sensitive to water and fertilizer concentrations, requiring a low-concentration and uniform supply of water and fertilizer. However, existing equipment often uses a single stirring blade at a fixed height, which makes it difficult to agitate the fertilizer sediment at the bottom of the supply cylinder. This easily leads to stratification of water and fertilizer in the cylinder, with a thinner upper layer and a more concentrated lower layer. When the thinner upper layer of water and fertilizer is extracted, the seedlings do not receive sufficient nutrients, and when the more concentrated lower layer of water and fertilizer is extracted, it can easily burn the delicate roots of the seedlings. Furthermore, it cannot address the issue of water level drop caused by reduced water and fertilizer application during the seedling stage, resulting in poor overall applicability. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a temperature-sensitive water and fertilizer supply device for Astragalus membranaceus cultivation. This device solves the problems of existing water and fertilizer equipment for Astragalus membranaceus cultivation, which often uses a single, fixed-height stirring blade, making it difficult to agitate the fertilizer at the bottom of the supply cylinder. This results in a situation where the upper layer of water and fertilizer is thin while the lower layer is concentrated. When extracting the thin upper layer, seedlings may lack sufficient nutrients; when extracting the concentrated lower layer, the delicate roots of seedlings may be scorched. Furthermore, it cannot adapt to the drop in water and fertilizer levels during the seedling stage, leading to poor overall applicability.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A temperature-sensitive water and fertilizer supply device for Astragalus membranaceus cultivation includes a trolley with a support fixed on it. A constant-temperature supply cylinder is fixed inside the support, and a cylinder cover is snapped onto the upper end of the cylinder. A drive motor is fixedly installed on the cylinder cover, and a rotating shaft is installed at the output end of the drive motor. Stirring blades are fixedly installed at equal intervals on the side wall of the rotating shaft. A turning plate is slidably installed inside the stirring blades. A threaded ring is evenly threaded on the rotating shaft. A limiting groove is formed on the side wall of the turning plate, and the threaded ring is disposed in the limiting groove. A sliding groove is formed inside the stirring blade, and a slider is fixedly installed on the side wall of the turning plate. The slider is slidably installed in the sliding groove. The drive motor drives the rotating shaft, stirring blades, and adjustable turning plate to rotate. The turning plate prevents water and fertilizer from settling, and the threaded ring adjusts the height of the turning plate to adapt to the liquid level, thereby achieving uniform mixing of water and fertilizer for Astragalus membranaceus cultivation and improving adaptability.

[0007] Preferably, a positioning ring is fixedly installed on the side wall of the support, a spray rod is inserted into the positioning ring, a connecting pipe is fixedly installed on the spray rod, and the connecting pipe is connected to the constant temperature supply cylinder. The positioning ring stabilizes the spray rod, and the connecting pipe conducts water to the constant temperature supply cylinder, which can gently spray the Astragalus seedlings, avoid displacement, ensure precise water and fertilizer supply, and meet the growth needs of the seedlings.

[0008] Preferably, the upper end of the trolley is fixedly installed with a pipe support, the lower end of the constant temperature supply cylinder is connected to a feeding pipe, the feeding pipe is installed on the pipe support, and valves are symmetrically installed on the feeding pipe. The pipe support fixes the feeding pipe to prevent shaking, and the valves precisely regulate the water and fertilizer flow rate, which is suitable for watering Astragalus membranaceus during the mature plant stage, avoids waste, and ensures a stable water and fertilizer supply for mature plants.

[0009] Preferably, irrigation pipes are symmetrically installed at both ends of the feeding pipe, and the irrigation pipes are connected to the feeding pipes. This allows for the simultaneous delivery of water and fertilizer, expanding the irrigation range for Astragalus membranaceus cultivation, improving the efficiency of large-scale batch irrigation, and ensuring uniform supply.

[0010] Preferably, a filter frame is fixedly installed on the lower end of the inner wall of the constant temperature supply cylinder, and filter screens are fixedly installed on the filter frame at equal intervals. The filter screens filter water and fertilizer impurities to prevent the feed pipe from being blocked. The filter frame fixes the position of the filter screens, reduces the frequency of equipment maintenance, and ensures continuous and uninterrupted irrigation for Astragalus planting.

[0011] Preferably, the lower end of the stirring blade is provided with an L-shaped groove, which is adapted to the filter screen frame and the filter screen. The L-shaped groove scrapes the filter screen as the stirring blade rotates, removing adhering impurities and maintaining filtration efficiency. No disassembly and cleaning are required, which reduces the operation difficulty of the water and fertilizer supply equipment for Astragalus planting.

[0012] Preferably, the stirring blades are evenly distributed along the axial direction of the rotating shaft, and two adjacent stirring blades are symmetrically arranged on the side wall of the rotating shaft. The uniform and symmetrical distribution of the stirring blades along the axial direction covers more areas of the constant temperature supply cylinder, reduces stirring dead corners, further improves the uniformity of water and fertilizer mixing, and avoids uneven absorption of astragalus.

[0013] Preferably, the inner diameter of the positioning ring is adapted to the outer diameter of the spray rod, the outer wall of the spray rod is fitted to the inner wall of the positioning ring, and the size of the positioning ring and the spray rod are adapted to each other, which enhances the sealing of the installation and prevents fertilizer leakage. At the same time, it is easy to insert and remove to adjust the spray position, and adapts to the needs of different planting areas of Astragalus membranaceus.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This equipment uses a drive motor to drive the stirring blades and an adjustable-height tilting plate to work together. When the tilting plate rotates, it can tilt the water and fertilizer in the constant temperature supply cylinder upwards, effectively enhancing the uniformity of water and fertilizer mixing and preventing fertilizer sedimentation. At the same time, the sliding height of the tilting plate can be adjusted by rotating the threaded ring to adapt to different water and fertilizer liquid levels in the constant temperature supply cylinder, greatly improving the adaptability and mixing effect of the device for water and fertilizer mixing operations.

[0022] This application provides a temperature-sensitive water and fertilizer supply device for Astragalus membranaceus cultivation. It effectively solves the problems of existing water and fertilizer equipment for Astragalus membranaceus cultivation, which often uses a fixed-height, single-blade agitator. This makes it difficult to agitate the fertilizer at the bottom of the supply cylinder, resulting in a thin upper layer and a concentrated lower layer of water and fertilizer. When extracting the thin upper layer, seedlings may lack sufficient nutrients; when extracting the concentrated lower layer, the delicate roots of seedlings may be scorched. Furthermore, this equipment cannot adapt to the drop in liquid level caused by reduced water and fertilizer usage during the seedling stage, resulting in poor overall applicability. This device uses a drive motor to drive the agitator blades in conjunction with an adjustable-height tilting plate. As the tilting plate rotates, it tilts the water and fertilizer in the constant-temperature supply cylinder upwards, effectively enhancing the uniformity of water and fertilizer mixing and preventing fertilizer sedimentation. Simultaneously, the sliding height of the tilting plate can be adjusted by rotating the threaded ring to adapt to different water and fertilizer levels in the constant-temperature supply cylinder, significantly improving the device's adaptability and mixing effect for water and fertilizer mixing operations.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the technical problems of existing water and fertilizer equipment for Astragalus planting, which mostly uses a single stirring blade of fixed height, making it difficult to stir the fertilizer at the bottom of the supply cylinder, easily resulting in a thin upper layer and a concentrated lower layer of water and fertilizer. When extracting the thin upper layer of water and fertilizer, the seedlings do not receive enough nutrients; when extracting the concentrated lower layer of water and fertilizer, the delicate roots of the seedlings are easily burned. Furthermore, it cannot adapt to the problem of liquid level drop when the amount of water and fertilizer used is reduced during the seedling stage, resulting in poor overall applicability. The overall idea is as follows: A temperature-sensitive water and fertilizer supply device for Astragalus planting includes a trolley 1, a support 2 fixed on the trolley 1, a constant temperature supply cylinder 3 fixed inside the support 2, a cylinder cover 11 snapped onto the upper end of the constant temperature supply cylinder 3, and a fixed device on the cylinder cover 11. Equipped with a drive motor 12, a rotating shaft 13 is mounted on the output end of the drive motor 12. Stirring blades 15 are fixedly mounted at equal intervals on the side wall of the rotating shaft 13. A tilting plate 17 is slidably mounted inside the stirring blades 15. A threaded ring 14 is evenly threaded on the rotating shaft 13. A limiting groove 19 is formed on the side wall of the tilting plate 17, and the threaded ring 14 is disposed within the limiting groove 19. A sliding groove 16 is formed inside the stirring blades 15. A slider 18 is fixedly mounted on the side wall of the tilting plate 17 and slidably mounted within the sliding groove 16. When the drive motor 12 drives the rotating shaft 13, stirring blades 15, and tilting plate 17 to rotate synchronously, the tilting plate 17 can penetrate deep into the bottom of the constant temperature supply cylinder 3, displacing the deposited fertilizer particles towards... The upward-turning mechanism completely breaks through the limitations of traditional stirring, which can only mix the upper layer of water and fertilizer, avoiding the stratification phenomenon of a thin upper layer and a concentrated lower layer. If stratification is not resolved, astragalus will grow slowly due to insufficient nutrients when absorbing the thin upper layer of water and fertilizer, and its roots will be easily burned when absorbing the concentrated lower layer of water and fertilizer. This structure ensures uniform water and fertilizer concentration throughout the cylinder, adapting to the stable water and fertilizer concentration requirements of astragalus at various growth stages. The threaded engagement between the threaded ring 14 and the rotating shaft 13, and the transmission action of the limiting groove 19, allow the tilting plate 17 to slide along the cavity of the stirring blade 15 by manually rotating the threaded ring 14, flexibly adjusting the extension length of the tilting plate 17. When the water and fertilizer level in the cylinder is high, the tilting plate 17 can be shortened to avoid contact with the constant temperature supply. The interference of the cylinder wall of the feed cylinder 3 is eliminated; when the liquid level drops, the extended tipping plate 17 can still contact the water and fertilizer to achieve agitation, solving the problem of failure of the traditional fixed-height stirring blade when the liquid level is low, and improving the adaptability of the device throughout the irrigation cycle. The sliding cooperation between the slider 18 and the chute 16 can limit the movement direction of the tipping plate 17, preventing it from deviating or getting stuck during sliding, and ensuring the stability of the adjustment process. If the tipping plate 17 deviates, it will lead to insufficient local stirring force and uneven mixing. This design can ensure the reliability of the stirring operation and further ensure that the water and fertilizer concentration absorbed by Astragalus is consistent. Moreover, the structure relies on the fixed support of the trolley 1 and the bracket 2, making the overall operation more stable and avoiding the impact of vibration on the stirring effect.

[0025] A positioning ring 4 is fixedly installed on the side wall of the support 2. A spray rod 5 is inserted into the positioning ring 4, and a connecting pipe 6 is fixedly installed on the spray rod 5. The connecting pipe 6 is connected to the constant temperature supply cylinder 3. The tight fit between the positioning ring 4 and the spray rod 5 can limit the radial sway of the spray rod 5 during operation. If the spray rod 5 shifts, the spraying range will be offset, and some seedlings will not be able to access water and fertilizer. This design can ensure the stability of the spraying range and meet the needs of precise supply in a small area during the seedling stage. The positioning ring 4 is fixed to the side wall of the support 2 by welding to ensure that its own position does not shift and to provide stable support for the spray rod 5. The connecting pipe 6 enables the constant temperature supply cylinder 3 to conduct to the spray rod 5. After opening the valve of the spray rod 5... Water and fertilizer can flow smoothly into the spray rod 5 along the connecting pipe 6 and be sprayed out from the spray hole in a mist or fine stream. The water flow has a small impact force: Astragalus seedlings have delicate and fragile root systems. Traditional high-pressure irrigation can easily wash away the soil and damage the root system. Gentle spraying can protect the root system while replenishing water and fertilizer, reducing the mortality rate of seedlings. The position of the spray rod 5 can be adjusted by inserting and pulling along the positioning ring 4. The spray point can be flexibly changed according to the row spacing of Astragalus planting: for example, when the row spacing is 30cm, the spray rod 5 can be adjusted to the middle of the two rows; when the row spacing is 40cm, the spray rod 5 can be pulled out to match the width, avoiding missed spraying or repeated spraying due to changes in row spacing. At the same time, the close fit can reduce the leakage of water and fertilizer from the gap between the positioning ring 4 and the spray rod 5, avoiding waste.

[0026] A pipe support 7 is fixedly installed on the upper end of the cart 1, and a feeding pipe 8 is connected to the lower end of the constant temperature supply cylinder 3. The feeding pipe 8 is installed on the pipe support 7, and valves 9 are symmetrically installed on the feeding pipe 8. The pipe support 7 fixes the feeding pipe 8 through a U-shaped groove. The pipe support 7 is fixed to the upper end of the cart 1 with bolts. It can bear the weight of the feeding pipe 8 and the internal water and fertilizer, and prevent the feeding pipe 8 from sagging and deforming due to its own weight, or shaking due to the impact of water flow. If the feeding pipe 8 is deformed, the water and fertilizer delivery will be blocked, and some mature plants will not be able to obtain water and fertilizer in time. The fixed support can ensure that the delivery channel is unobstructed and meet the needs of continuous and stable supply during the mature plant stage.

[0027] The symmetrically installed valves 9 can respectively regulate the water and fertilizer flow at both ends of the feeding pipe 8: Astragalus plants have well-developed root systems and require a large amount of water and fertilizer, but the growth status of mature plants in different areas may vary. By adjusting the valves 9, the flow in the edge area can be reduced and the flow in the middle area can be increased to avoid uneven growth caused by a one-size-fits-all supply. At the same time, the valves 9 on one side can be closed to achieve one-sided irrigation, which can meet the local fertilization needs of the planting area.

[0028] The flange connection between the feeding pipe 8 and the constant temperature supply cylinder 3 can enhance the sealing of the connection and prevent water and fertilizer from leaking at the starting point of the delivery. If leakage occurs here, it will not only waste water and fertilizer, but also cause insufficient pressure in the feeding pipe 8, reducing the amount of water and fertilizer obtained by the plants at the far end, thus affecting the overall growth. The flange connection can minimize the leakage rate and improve the delivery efficiency.

[0029] Irrigation pipes 10 are symmetrically installed at both ends of the feeding pipe 8. The irrigation pipes 10 are connected to the feeding pipe 8. The irrigation pipes 10 are sealed to both ends of the feeding pipe 8 through threaded joints to achieve water and fertilizer separation. This transforms the single-channel delivery of the feeding pipe 8 into multi-channel coverage. Traditional single feeding pipes can only irrigate a small area around the pipe, while the irrigation pipes 10 can cover the planting area 1-2 meters on both sides of the feeding pipe 8 after extending to both sides, greatly reducing the number of times the equipment needs to be moved.

[0030] The sealing design of the threaded joint can prevent leakage at the branch point and ensure that the water and fertilizer flow of each irrigation pipe 10 is uniform. If leakage occurs, the plants near the feeding pipe 8 will receive excessive water and fertilizer, while the plants at the far end will receive insufficient water and fertilizer. The sealed connection can ensure that each row of Astragalus receives the same amount of water and fertilizer, avoiding the polarization of growth caused by the difference in flow.

[0031] The length of the irrigation pipe 10 can be flexibly adjusted according to the row spacing of Astragalus membranaceus planting to adapt to different planting patterns: whether it is dense planting or sparse planting, the entire area can be covered by changing the length of the irrigation pipe 10, thus improving the versatility of the device.

[0032] A filter frame 21 is fixedly installed at the lower end of the inner wall of the constant temperature supply cylinder 3. Filters 22 are fixedly installed at equal intervals on the filter frame 21. The filters 22 can intercept impurities such as undissolved fertilizer particles and soil debris in the water and fertilizer. If impurities enter the feeding pipe 8 or irrigation pipe 10, they will block the pipe holes and cause irrigation to be interrupted. The filters 22 can keep the impurities in the constant temperature supply cylinder 3 to ensure that the delivery channel is unobstructed and avoid the interruption of the supply to some plants due to blockage.

[0033] The filter frame 21 is a ring structure, which is fixed to the lower end of the inner wall of the thermostatic supply cylinder 3 by welding. It fits completely with the inner wall of the thermostatic supply cylinder 3, and its inner diameter corresponds to the lower outlet of the thermostatic supply cylinder 3. This design ensures that all outflowing water and fertilizer must pass through the filter screen 22 without any dead corners: traditional square filter screens are prone to forming circumference in corners, and unfiltered water and fertilizer flow out directly, while the ring filter frame 21 can achieve full flow filtration, further reducing the risk of clogging.

[0034] The filter screen 22 is made of stainless steel or nylon and is resistant to water and fertilizer corrosion: the water and fertilizer commonly used in Astragalus cultivation are corrosive. Traditional iron filter screens are prone to rust and damage, while the stainless steel / nylon filter screen 22 has a service life of 1-2 years, reducing the maintenance cost of frequent filter screen replacement and preventing rust from mixing into the water and fertilizer and affecting the quality of Astragalus.

[0035] An L-shaped groove 20 is provided at the lower end of the stirring blade 15. The L-shaped groove 20 is adapted to the filter screen frame 21 and the filter screen 22. When the stirring blade 15 rotates, the transverse section of the L-shaped groove 20 at the lower end of the stirring blade 15 will contact the surface of the filter screen 22 and scrape the filter screen 22 synchronously with the stirring blade 15. After long-term use, fertilizer residue is easily attached to the surface of the filter screen 22. If it is not cleaned, it will clog the holes of the filter screen 22, resulting in a decrease in filtration efficiency. The scraping action of the L-shaped groove 20 can remove the residue in real time and maintain the filtration capacity of the filter screen 22 without manual cleaning.

[0036] Cleaning can be achieved without disassembling the thermostatic supply cylinder 3 or the filter frame 21 and filter 22: Traditional filter cleaning requires stopping the machine and removing the cylinder cover 11 and filter frame 21, which takes 30-60 minutes and interrupts the irrigation operation. However, this self-cleaning structure can complete the cleaning simultaneously during the stirring of the stirring blade 15, without downtime, ensuring continuous irrigation.

[0037] The longitudinal section of the L-shaped groove 20 does not contact the filter screen 22, and only the transverse section is scraped. This design can avoid affecting the flow of water and fertilizer during the scraping process, and at the same time prevent the L-shaped groove 20 from damaging the surface of the filter screen 22. If the entire screen is scraped, it is easy to cause the filter screen 22 to deform. The segmented design can balance the cleaning effect and the protection of the filter screen 22, and extend the service life of the filter screen 22.

[0038] The stirring blades 15 are evenly distributed along the axis of the rotating shaft 13, and two adjacent stirring blades 15 are symmetrically arranged on the side wall of the rotating shaft 13. The stirring blades 15 are evenly distributed along the axis of the rotating shaft 13, which can cover the water and fertilizer areas at different heights inside the constant temperature supply cylinder 3. Traditional stirring blades are only concentrated in the middle of the rotating shaft, which easily forms stirring dead corners at the bottom and top of the cylinder, resulting in uneven mixing of water and fertilizer in the dead corners. The evenly distributed stirring blades 15 can achieve synchronous stirring of the upper and lower layers, completely eliminate dead corners, and ensure that the water and fertilizer concentration is consistent throughout the cylinder.

[0039] Each set of stirring blades 15 is symmetrically welded on the side wall of the rotating shaft 13, which can balance the force on the rotating shaft 13 when it rotates. If the stirring blades 15 are not symmetrical, the rotating shaft 13 will sway eccentrically due to uneven force, which will increase the load on the drive motor 12 and easily burn out the drive motor 12 after long-term use. Symmetrical distribution can balance the force on the rotating shaft 13, reduce the load on the drive motor 12, and extend the service life of the drive motor 12.

[0040] The combination of axial uniformity and radial symmetry creates a three-dimensional mixing effect: the mixing blade 15 can not only mix horizontally, but the turning plate 17 can also turn vertically. The two work together to shorten the water and fertilizer mixing time by 20%-30%, improve work efficiency, and meet the needs of rapid supply in Astragalus membranaceus planting.

[0041] The inner diameter of the positioning ring 4 is matched with the outer diameter of the spray rod 5, and the outer wall of the spray rod 5 is fitted with the inner wall of the positioning ring 4. The inner diameter of the positioning ring 4 is matched with the outer diameter of the spray rod 5. The two are in a transition fit. After the spray rod 5 is inserted, the outer wall is completely fitted with the inner wall of the positioning ring 4. This fit precision can prevent water and fertilizer from leaking from the gap. Leaking water and fertilizer will drip onto the cart 1 and the ground, which will not only waste nutrients but also corrode the frame of the cart 1. The transition fit can reduce the leakage rate to below 0.5%.

[0042] The close fit can limit the radial sway of the spray rod 5: the water flow impact during spraying will cause the spray rod 5 to sway slightly. If the sway is too large, the spray range will be offset, resulting in some seedlings being missed. This structure can control the sway amplitude to a minimum, ensuring that the spray range accurately covers the target area; the positioning ring 4 is fixed to the side wall of the bracket 2, providing a stable positioning reference for the spray rod 5.

[0043] Although designed for close integration, the spray rod 5 can still be manually inserted and removed for adjustment: different planting densities of Astragalus require different spraying positions. During the seedling stage, it needs to be sprayed close to the seedlings, while during the mature stage, it can be sprayed slightly further away. The insertable design allows for flexible adjustment of the extension length of the spray rod 5 to adapt to different planting densities, avoiding the need to replace spraying components due to changes in density and reducing operating costs.

[0044] To address the problems existing in the prior art, this utility model provides a temperature-sensitive water and fertilizer supply device for Astragalus membranaceus cultivation. This device uses a drive motor to drive the stirring blades and an adjustable-height tilting plate to work together. When the tilting plate rotates, it can tilt the water and fertilizer in the constant-temperature supply cylinder upwards, effectively enhancing the uniformity of water and fertilizer mixing and preventing fertilizer sedimentation. At the same time, the sliding height of the tilting plate can be adjusted by rotating the threaded ring to adapt to different water and fertilizer liquid levels in the constant-temperature supply cylinder, greatly improving the adaptability and mixing effect of the device for water and fertilizer mixing operations.

[0045] Working principle:

[0046] First, when using the equipment, water and fertilizer can be added into the constant temperature supply cylinder 3. At this time, the drive motor 12 can be started. Under the action of the drive motor 12, the rotating shaft 13 will rotate, and the rotating shaft 13 will drive the stirring blade 15 to rotate. The rotation of the stirring blade 15 will stir and mix the water and fertilizer in the constant temperature supply cylinder 3. The rotation of the stirring blade 15 will also drive the turning plate 17 to rotate. The turning plate 17 will turn the water and fertilizer in the constant temperature supply cylinder 3 upward, so that the equipment can turn the water and fertilizer at the same time, further enhancing the mixing effect and preventing the water and fertilizer from settling.

[0047] The second step is to adjust the tilting plate 17. At this time, the threaded ring 14 can be rotated on the rotating shaft 13. Since the two are threadedly connected, the rotation of the threaded ring 14 will drive the tilting plate 17 to move vertically inside the stirring blade 15. At this time, the slider 18 on the tilting plate 17 will move vertically inside the chute 16, thereby adjusting the working height of the three tilting plates 17 and enhancing the applicability of the equipment.

[0048] The third step is to open the valve 9 on the feeding pipe 8 and then irrigate the astragalus through the limiting groove 19. Alternatively, the water and fertilizer inside the constant temperature supply cylinder 3 can be extracted from the connecting pipe 6 through the spray rod 5 and sprayed onto the astragalus. Two fertilization methods are available.

[0049] In the fourth step, during batch irrigation, water and fertilizer can flow into the feeding pipe 8 through the filter screen 22 on the filter frame 21. At this time, the filter screen 22 can filter the water and fertilizer at the bottom of the constant temperature supply cylinder 3, effectively preventing clogging. In addition, during the process of stirring the water and fertilizer inside the constant temperature supply cylinder 3 by the stirring blade 15, the filter screen 22 will also be scraped at the same time, which can effectively remove the impurities and dust adhering to the filter screen 22, further enhancing its anti-clogging effect.

[0050] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
