Description

Technical Field

[0001] This utility model relates to the field of drip irrigation technology, and in particular to a drip irrigation inlet adjustment device based on dynamic soil moisture monitoring. Background Technology

[0002] Drip irrigation technology has developed rapidly, with various types of drip irrigation equipment. However, most are surface drip irrigation systems, which cannot directly reach the root system of plants, still resulting in a certain amount of water loss due to evaporation and runoff. This is especially true for crops with deep root systems, where the irrigation effect of drip irrigation equipment still has room for improvement. Therefore, it is essential to develop a drip irrigation system that can target plant roots and reduce water loss caused by evaporation and runoff. Agricultural irrigation mainly refers to irrigation operations in agricultural areas, and its methods are generally divided into surface irrigation, conventional irrigation, and micro-irrigation.

[0003] For example, patent number CN220191684U discloses a quantitative drip irrigation device for fruits and vegetables. This device uses drip irrigation pipes on both sides of a liquid hopper, and a rotating adjusting pipe on each drip irrigation pipe. The adjusting pipe allows for adjustment of the length of the conical opening of a conical adjusting rod inside the drip irrigation pipe, thereby regulating the water flow rate from the liquid hopper into the adjusting pipe through the conical opening. This achieves adjustable quantitative drip irrigation. The device has a simple structure, is easy to operate, has strong applicability, and is convenient for a wide range of users. For example, patent number CN221901787U discloses an insertable drip irrigation device for crops. By pulling the pressing block, the connecting rod moves upward, which in turn moves the mounting block and rubber block upward as a whole. The movement of the rubber block opens the corresponding drip irrigation port, allowing water to flow out. The height of the adjusting tube can be adjusted according to the different heights of the plant roots to open the corresponding drip irrigation port, thus allowing the water to be better absorbed by the plant roots, avoiding water waste and reducing costs.

[0004] However, most existing drip irrigation inlet adjustment devices require staff to manually adjust the drip rate according to soil conditions, which means that staff need to monitor the soil for a long time, affecting their work efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a drip irrigation inlet adjustment device based on dynamic soil moisture monitoring. This solves the problem that most existing drip irrigation inlet adjustment devices require staff to manually adjust the drip rate according to soil conditions, which leads to staff needing to monitor the soil for extended periods and affects their work efficiency.

A control panel is fixedly connected to the front end of the device base. The control panel is electrically connected to the monitoring device, the electronic valve, and the servo motor. The monitoring device, the electronic valve, and the servo motor can be controlled separately through the control panel.

[0009] Preferably, both drip irrigation port A and drip irrigation port B have a discharge port on their inner sides, and the diameter of the discharge port on the inner side of drip irrigation port B is half the diameter of the discharge port on the inner side of drip irrigation port A.

[0010] Preferably, a flow guide seat is provided on the outer side of the bottom of the discharge seat, and a flow guide groove is provided on the top surface of the flow guide seat. The number of flow guide grooves is the same as that of drip irrigation port A and drip irrigation port B, and the flow guide grooves correspond one-to-one with drip irrigation port A and drip irrigation port B.

[0011] Preferably, one end of the connecting rod is provided with a rotating hole inside the control panel and the discharge seat.

Combined with a microprocessor, it intelligently determines irrigation needs and switches between high flow (drip inlet A) and low flow (drip inlet B) modes via a servo motor, connecting rod, and discharge plug. This avoids over- or under-irrigation, improves water and fertilizer utilization efficiency, and automatically locks the discharge plug after it rotates into position using a limit block, limit groove, and connecting spring. This effectively prevents accidental rotation caused by water and fertilizer impact, ensuring accurate alignment of the drip irrigation inlet and guaranteeing irrigation stability and continuity.

[0016] 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.

[0017] Please see Figures 1-4This utility model provides an embodiment: a drip irrigation inlet adjustment device based on dynamic soil moisture monitoring, including a device base 1, a storage tank 2 fixedly connected to the top of the device base 1, a monitoring device 3 fixedly connected to the rear end of the storage tank 2, a discharge seat 8 provided at the bottom of the storage tank 2, drip irrigation inlets A12 and B13 respectively provided on the outer side of the discharge seat 8, the drip irrigation inlets A12 and B13 being evenly distributed on the outer surface of the discharge seat 8, a limit seat 10 fixedly provided at the bottom of the discharge seat 8, and a servo motor fixedly connected to the bottom of the limit seat 10. The output end of the servo motor 9 is fixedly connected to a connecting rod 18. One end of the connecting rod 18 extends through the limiting seat 10 to the inside of the storage tank 2. A discharge plug 15 is provided on the inner wall of the storage tank 2 at one end of the connecting rod 18. (A discharge groove 16 is opened on the outer surface of the discharge plug 15. The outer wall of the discharge plug 15 fits against the inner wall of the discharge seat 8. The discharge plug 15 is made of wear-resistant and corrosion-resistant high-molecular composite material. Its outer surface is covered with a silicone sealing layer to ensure that it keeps in close contact with the inner wall of the discharge seat 8 during rotation to prevent liquid leakage.)

[0018] Please see Figures 1-2 In this embodiment, the top of the storage tank 2 is threadedly connected to a device top cover 5. Both sides of the top surface of the device top cover 5 are provided with feeding seats 6. The top of the feeding seat 6 has a feeding port 7. The bottom end of the feeding port 7 passes through the device top cover 5 and connects to the storage tank 2. The feeding port 7 and the storage tank 2 are connected in a through connection. The monitoring device 3 includes a humidity sensor (the humidity sensor is a multi-point distributed sensor array, which can simultaneously monitor soil moisture at different depths or in different areas; the control panel 4 makes irrigation decisions based on the weighted average of multi-point data, improving irrigation uniformity). One end of the humidity sensor can be inserted into the inner side of the soil. An electronic valve 11 is provided on one side of the discharge seat 8. The front end of the device base 1 is fixedly connected to the control panel 4, which controls... Panel 4 is electrically connected to monitoring device 3, electronic valve 11, and servo motor 9. Monitoring device 3, electronic valve 11, and servo motor 9 can be controlled separately through control panel 4. (Control panel 4 integrates a microprocessor. The microprocessor automatically determines the current irrigation demand level based on the soil moisture content data collected in real time by the humidity sensor, and controls the rotation angle of servo motor 9 accordingly, so that the discharge groove 16 on the discharge plug 15 is aligned with drip irrigation port A12 or drip irrigation port B13, thereby switching between high flow rate and low flow rate drip irrigation mode. When the soil moisture content is lower than the preset threshold, drip irrigation port A12 is activated for high flow rate irrigation. When the soil moisture content is close to but not saturated, drip irrigation port B13 is activated for fine-tuning supplementary irrigation.)

[0019] Please see Figures 3-4In this embodiment, both drip inlets A12 and B13 have discharge ports on their inner sides. The diameter of the discharge port on the inner side of drip inlet B13 is half the diameter of the discharge port on the inner side of drip inlet A12. A guide seat 14 is provided on the outer side of the bottom end of the discharge seat 8. A guide groove 17 is provided on the top surface of the guide seat 14. The number of guide grooves 17 is the same as that of drip inlets A12 and B13, and the guide grooves 17 correspond one-to-one with drip inlets A12 and B13. One end of the connecting rod 18 is provided with a rotating hole on the inner side of the control panel 4 and the discharge seat 8. One end of the connecting rod 18 passes through the rotating hole and connects to the discharge plug 15. When the motor 9 drives the connecting rod 18 to rotate, the connecting rod 18 drives the discharge plug 15 to rotate on the inner wall of the discharge seat 8. A sealing gasket is provided on the inner wall of the rotating hole. Limiting blocks 19 are movably connected to both sides of the connecting rod 18 on the outer surface of the limiting seat 10. A connecting spring 20 is fixedly connected to the bottom end of the limiting block 19 on the inner wall of the limiting seat 10. The limiting block 19 is connected to the limiting seat 10 through the connecting spring 20. A limiting groove 21 is opened on the outer surface of the connecting rod 18 at one end of the limiting block 19. When the connecting rod 18 rotates to a suitable angle, one end of the limiting block 19 cooperates with the connecting spring 20 to be inserted into the inner side of the limiting groove 21.

[0020] During operation, the device is placed in a suitable position, and the water and fertilizer to be drip-irrigated are poured into the storage tank 2 through the inlet 7. Then, the power is turned on and the device is started. A monitoring device 3 is set at the rear of the storage tank 2. The monitoring device 3 includes a humidity sensor. One end of the humidity sensor is inserted into the soil. The humidity sensor is a multi-point distributed sensor array, which can simultaneously monitor soil moisture at different depths or in different areas. The control panel 4 integrates a microprocessor. Based on the real-time soil moisture data collected by the humidity sensor, the microprocessor automatically determines the current irrigation demand level and controls the servo motor 9 to rotate the connecting rod 18 so that the discharge slot 16 on the discharge plug 15 is aligned with the drip irrigation port A. The connection rod 18 can be switched between high-flow and low-flow drip irrigation modes by using drip irrigation port A12 or drip irrigation port B13. When the soil moisture content is lower than the preset threshold, drip irrigation port A12 is used for high-flow irrigation. When the soil moisture content is close to but not saturated, drip irrigation port B13 is used for fine-tuning supplementary irrigation. The two sides of the connecting rod 18 are movably connected to the limiting block 19 on the outer surface of the limiting seat 10. One end of the limiting block 19 is provided with a limiting groove 21 on the outer surface of the connecting rod 18. When the connecting rod 18 is rotated to a suitable angle, one end of the limiting block 19, in conjunction with the connecting spring 20, is inserted into the inner side of the limiting groove 21, thereby locking the connecting rod 18 and preventing the discharge plug 15 from rotating under the impact of water and fertilizer when drip irrigation is performed at the discharge seat 8, which would affect the efficiency of drip irrigation. Compared to CN220191684U, a quantitative drip irrigation device for fruits and vegetables, which uses drip irrigation pipes on both sides of the hopper and a rotating adjusting pipe on the drip irrigation pipe, the length of the tapered opening of the adjusting rod inside the tapered structure of the adjusting pipe can be adjusted by rotating the adjusting pipe. This adjusts the water flow rate from the hopper into the adjusting pipe through the tapered opening, thus achieving adjustable quantitative drip irrigation. This drip irrigation device has a simple structure, is easy to operate, and has strong applicability, making it convenient for a wide range of users. Also compared to CN221901787U, an insert-type drip irrigation device for crops, which uses a pressing block to move a connecting rod upwards, which in turn moves the mounting block and rubber block upwards as a whole. The movement of the rubber block causes the corresponding drip inlet to spray water. The system opens the drip irrigation nozzle, allowing water to flow out. The height of the regulating pipe is adjusted according to the different root heights of the plants, opening the corresponding drip irrigation nozzle to ensure better water absorption by the plant roots, avoiding water waste and reducing costs. This application uses a humidity sensor to monitor soil moisture content at different areas or depths, and a microprocessor to intelligently determine irrigation needs. A servo motor, connecting rod, and discharge plug switch between high flow (drip irrigation nozzle A) and low flow (drip irrigation nozzle B) modes to avoid over- or under-irrigation, improving water and fertilizer utilization efficiency. Furthermore, the system uses a limit block, limit groove, and connecting spring to automatically lock the discharge plug after it rotates into position, effectively preventing accidental rotation caused by water and fertilizer impact, ensuring accurate alignment of the drip irrigation nozzle, and guaranteeing irrigation stability and continuity.

[0021] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
