Description

Technical Field

[0001] This utility model belongs to the field of agricultural planting technology, specifically relating to a water-saving irrigation device for konjac planting. Background Technology

[0002] Konjac is a crop that thrives in moist conditions but is susceptible to waterlogging. Its growth requires strict water control; it needs sufficient water to sustain growth, but excessive water accumulation can lead to root rot. Traditional irrigation methods for konjac cultivation mainly involve flood irrigation or sprinkler irrigation. Flood irrigation not only wastes water resources but also easily causes soil compaction and waterlogging, which is detrimental to konjac growth. While sprinkler irrigation improves irrigation uniformity to some extent, it still suffers from problems such as difficulty in precisely controlling the irrigation amount and significant water loss due to evaporation.

[0003] Currently, some water-saving irrigation devices, such as drip irrigation systems, have emerged on the market. However, existing drip irrigation devices suffer from drawbacks in konjac cultivation, such as easy clogging of drippers and unreasonable distribution of irrigation areas. They cannot meet the differentiated water requirements of konjac at different growth stages, making it difficult to achieve efficient water-saving irrigation. Therefore, there is an urgent need to design a water-saving irrigation device suitable for konjac cultivation to solve the problems existing in current technologies. Summary of the Invention

[0004] To overcome the shortcomings of existing drip irrigation devices in konjac cultivation, such as easy clogging of drippers and unreasonable distribution of irrigation areas, which fail to meet the differentiated water requirements of konjac at different growth stages and make it difficult to achieve efficient water-saving irrigation, this utility model provides a water-saving irrigation device for konjac cultivation. By optimizing the irrigation structure and control method, it achieves precise irrigation, reduces water waste, improves irrigation efficiency, meets the water requirements of konjac growth, and reduces the risk of dripper clogging.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A water-saving irrigation device for konjac cultivation mainly includes a water storage tank, a filter assembly, a main pipeline, branch pipelines, and drip irrigation tape; the water storage tank has an inlet at the top and an outlet at the bottom, the outlet being connected to the inlet of the filter assembly through a pipeline, the filter assembly including a primary filter screen, an activated carbon filter layer, and a precision filter screen, which are sequentially arranged in the filter chamber, the outlet of the filter assembly being connected to the main pipeline, the other end of the main pipeline being closed, a booster pump being provided on the main pipeline, and multiple branch pipelines being evenly connected to the main pipeline, the branch pipelines being perpendicular to the main pipeline, and multiple drip irrigation tape connection ports being spaced apart on each branch pipeline, the drip irrigation tape being connected to the branch pipeline through the connection ports.

[0006] Furthermore, the drip irrigation tape includes an outer tube and an inner tube. The outer tube has multiple drip holes evenly distributed on it. The inner tube is fitted inside the outer tube and has adjustment holes corresponding to the drip holes. One end of the inner tube is connected to a rotating adjustment component. The rotating adjustment component can drive the inner tube to rotate, thereby changing the overlapping area between the adjustment hole and the drip hole.

[0007] Furthermore, the soil in which konjac is grown is also equipped with a humidity sensor to monitor soil moisture in real time.

[0008] Furthermore, the device also includes a control assembly comprising a controller and a solenoid valve, the solenoid valve being mounted on a branch pipeline, and the controller being electrically connected to the solenoid valve, the booster pump, the humidity sensor, and the rotary adjustment component.

[0009] Furthermore, a liquid level sensor is also provided on the outer wall of the water storage tank, and the liquid level sensor is electrically connected to the controller.

[0010] The beneficial effects of this utility model are as follows: The filter component of this utility model adopts a multi-stage filtration structure to fully filter irrigation water and effectively remove impurities from the water. At the same time, the drip irrigation tape adopts an adjustable inner tube structure, which can clean the drip holes to a certain extent during the adjustment of water volume, reduce the risk of drip head clogging, and extend the service life of the irrigation device. The layout of the branch pipes and main pipes, as well as the setting of the drip irrigation tape, can make the irrigation area evenly distributed, ensuring that the konjac plants receive sufficient and uniform water supply, which is conducive to the growth and development of konjac. The whole process is automatically controlled by the controller, eliminating the need for frequent manual operation, reducing labor intensity, improving irrigation efficiency, and also reducing water waste caused by improper human operation.

[0016] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0017] This utility model discloses a water-saving irrigation device for konjac cultivation. The water-saving irrigation device for konjac cultivation mainly includes a water storage tank 1, a filter assembly 2, a main pipe 3, branch pipes 4, and drip irrigation tape 5. The water storage tank 1 has an inlet 8 at the top and an outlet 9 at the bottom. The outlet 9 is connected to the inlet end of the filter assembly 2 through a pipe. The filter assembly 2 includes a primary filter screen, an activated carbon filter layer, and a precision filter screen, which are arranged sequentially in the filter chamber. The outlet end of the filter assembly 2 is connected to the main pipe 3, and the other end of the main pipe 3 is closed. A booster pump 6 is provided on the main pipe 3, and multiple branch pipes 4 are evenly connected to the main pipe 3. The branch pipes 4 are arranged perpendicular to the main pipe 3. Multiple drip irrigation tape 5 connection ports are arranged at intervals on each branch pipe 4, and the drip irrigation tape 5 is connected to the branch pipe 4 through the connection ports.

[0018] The drip irrigation tape 5 includes an outer tube 501 and an inner tube 502. The outer tube 501 has a plurality of drip holes 11 evenly distributed on it. The inner tube 502 is fitted inside the outer tube 501 and has adjustment holes 12 corresponding to the drip holes 11. One end of the inner tube 502 is connected to a rotating adjustment component 503. The rotating adjustment component 503 can drive the inner tube 502 to rotate, thereby changing the overlapping area of ​​the adjustment hole 12 and the drip hole 11. The drip irrigation tape 5 adopts the structure of the outer tube 501 and the inner tube 502 fitted together. By rotating the inner tube 502 through the rotating adjustment component 503, the overlapping area of ​​the adjustment hole 12 and the drip hole 11 can be changed, which can achieve precise flow rate adjustment according to the water requirements of konjac at different growth stages.

[0019] The soil in which konjac is grown is also equipped with a humidity sensor to monitor soil moisture in real time.

[0020] The device also includes a control component 7, which includes a controller and a solenoid valve 10. The solenoid valve 10 is installed on the branch pipe 4. The controller is electrically connected to the solenoid valve 10, the booster pump 6, the humidity sensor, and the rotary adjustment component 503. The humidity sensor monitors the soil moisture in real time and transmits the monitoring data to the controller. The controller controls the opening and closing of the solenoid valve 10, the working state of the booster pump 6, and the rotation angle of the rotary adjustment component 503 according to the preset soil moisture range and the received humidity data, so as to realize automated and precise irrigation.

[0021] A liquid level sensor is also installed on the outer wall of the water storage tank 1. The liquid level sensor is electrically connected to the controller. When the water level in the water storage tank 1 is lower than the preset value, the liquid level sensor transmits a signal to the controller, and the controller issues an alarm to remind the staff to replenish the water in time.

[0022] Working Process: In practical use, irrigation water is first injected into the water storage tank 1 through the inlet 8. After passing through multiple stages of filtration including the primary filter, activated carbon filter layer, and precision filter of the filter assembly 2, the water enters the main pipeline 3. The booster pump 6 is turned on, and under the action of the booster pump 6, the water flows through the main pipeline 3 and is distributed to each branch pipeline 4. Then, it enters the drip irrigation tape 5 through the branch pipeline 4. When installing the drip irrigation tape 5, the position of the drip irrigation tape 5 and the direction of the drip holes 11 are reasonably adjusted according to the planting spacing of the konjac plants to ensure that the irrigation water can be accurately dripped to the vicinity of the konjac roots. The humidity sensor is buried in the soil of the konjac planting area. Its burial depth and position are determined according to the distribution of the konjac root system to ensure accurate monitoring of soil moisture. The liquid level sensor is installed at a suitable position on the outer wall of the water storage tank 1 to monitor the water level in the water storage tank 1 in real time. The controller is installed in a place that is easy to operate and observe, and is electrically connected to the solenoid valve 10, the booster pump 6, the humidity sensor, the rotary adjustment component 503, and the liquid level sensor. When the soil moisture in the konjac planting area falls below the preset lower limit, the humidity sensor transmits a signal to the controller. The controller then opens the solenoid valve 10 and simultaneously starts the booster pump 6, allowing irrigation water to drip into the soil through the drip irrigation tape 5. Based on the difference between the soil moisture and the preset value, the controller adjusts the drip rate of the drip irrigation tape 5 using the rotating adjustment component 503. When the soil moisture reaches the preset upper limit, the controller closes the solenoid valve 10, stopping irrigation. During irrigation, if the water level in the storage tank 1 falls below the preset value, the level sensor transmits a signal to the controller, which issues an alarm, reminding staff to replenish water in the storage tank 1. Staff can manually adjust the drip rate of the drip irrigation tape 5 using the rotating adjustment component 503 to cope with special weather conditions or the specific growth needs of konjac.

[0023] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
