Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, and in particular to a water-saving crop root irrigation device. Background Technology

[0002] Crops refer to all kinds of plants cultivated in agriculture, including food crops (such as wheat, rice, and corn), cash crops (such as cotton, rapeseed, and sugarcane), vegetable crops (such as cabbage, tomatoes, and cucumbers), and fruit crops (such as apples, bananas, and grapes). Irrigation is necessary because natural rainfall often cannot meet the needs of crop growth and development. Irrigation can supplement crops with water, ensuring an adequate water supply at different growth stages to maintain normal physiological activities such as photosynthesis, nutrient absorption, and transport. It can also regulate soil temperature and fertility, improve the microclimate in the field, and create environmental conditions conducive to crop growth, thereby increasing crop yield and quality.

[0003] In current agricultural production, existing crop irrigation methods are relatively simple and traditional, with the vast majority still relying on manual irrigation. Farmers often need to personally carry irrigation tools, moving back and forth in the fields to water crops section by section; or they use a direct spraying method, allowing water to be sprayed directly onto the crop plants from nozzles. However, this traditional irrigation method exposes many drawbacks. From the perspective of water resource utilization, it results in a significant waste of water resources. Due to the lack of precise irrigation control, some water evaporates directly into the air during spraying, while some flows outside the soil, failing to be fully absorbed and utilized by crops. Moreover, judging soil moisture status solely by visual observation is extremely limited. Farmers can only rely on experience and intuitive visual perception to infer whether the soil is dry or lacking water. This method of judgment lacks scientific rigor and accuracy, easily leading to misjudgments—either insufficient irrigation, affecting normal crop growth, or over-irrigation, further exacerbating water waste. In terms of work efficiency, both manual irrigation and direct sprinkler irrigation require significant investment of manpower and time. Farmers need to work in the fields for extended periods, resulting in high labor intensity but very low efficiency. From an energy-saving and environmental perspective, traditional irrigation methods not only waste water resources but may also consume excessive amounts of electricity due to the overuse of pumps and other equipment, which is inconsistent with the concept of sustainable development. Furthermore, during direct sprinkler irrigation, if water droplets remain on the leaves or fruits of crops and do not evaporate in time, under the midday sun, these residual water droplets act like small convex lenses, focusing sunlight and causing a sharp increase in local temperature, thus causing scorching and other damage to crops, affecting their quality and yield.

[0004] Therefore, those skilled in the art have provided a water-saving crop root irrigation device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a water-saving crop root irrigation device. When insufficient soil moisture is detected, it can achieve automated irrigation, directly irrigating the roots. It has a simple structure, is energy-saving and environmentally friendly, and has high irrigation efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water-saving crop root irrigation device, including an electrical waterproof housing, a clamp fixedly installed at the rear end of the electrical waterproof housing, a soil moisture sensor fixedly installed at the lower end of the clamp, and two adjusting rods rotatably installed inside the rear end of the clamp, with threaded holes opened at the rear ends of both adjusting rods.

[0007] The threaded hole is fitted with a root irrigation rod, and the upper ends of the two root irrigation rods are rotatably connected to a sub-tube via a bearing. The front ends of the two sub-tubes are connected to a main tube via a tee connector, and a solenoid valve is installed near the front end of the main tube.

[0008] Furthermore, the upper end of the waterproof protective shell of the electrical appliance is provided with a battery compartment, the upper end of the battery compartment is fitted with a sealing cover, and a lithium battery is installed inside the battery compartment.

[0009] Furthermore, a controller is embedded inside the waterproof housing of the electrical appliance, and the controller is electrically connected to the lithium battery, the soil moisture sensor, and the solenoid valve.

[0010] Furthermore, a limit block is fixedly provided at the upper end of the clamp.

[0011] Furthermore, the front end of the main pipe passes through the limiting block and extends to the front end of the electrical waterproof casing.

[0012] Furthermore, the main pipe and the sub-pipe are flexible hoses, the lower end of the root irrigation rod is provided with a water spray hole, and the root irrigation rod is a rigid pipe with threads on its outer surface.

[0013] This utility model has the following beneficial effects:

[0014] This invention proposes a water-saving crop root irrigation device. It uses a soil moisture sensor to monitor soil moisture in real time and automatically controls a solenoid valve for precise irrigation, directly delivering water to the crop roots. This significantly reduces water waste, avoids evaporation and loss as in traditional irrigation methods, and greatly improves water utilization efficiency. The device operates automatically without manual intervention, reducing farmers' labor intensity and time costs, and increasing work efficiency. Its simple structure makes installation and maintenance convenient. The root irrigation rod can be flexibly adjusted in position and depth to meet the needs of different crops. Powered by a lithium battery, both the soil moisture sensor and the solenoid valve operate intermittently, resulting in low energy consumption and conforming to the sustainable development concept of energy conservation and environmental protection. The spray hole at the lower end of the root irrigation rod is designed for slow overflow, preventing soil clogging and ensuring continuous and efficient irrigation. Direct root irrigation avoids water droplets remaining on leaves or fruits, preventing scorching under direct sunlight, protecting crop health, and improving yield and quality. The overall design is scientific and reasonable, easy to operate, and suitable for the irrigation needs of various crops, showing good prospects for widespread application.

[0021] 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.

[0022] Reference Figures 1-4An embodiment of this utility model is provided: a water-saving crop root irrigation device, including an electrical waterproof housing 1, a clamp 10 fixedly installed at the rear end of the electrical waterproof housing 1, a soil moisture sensor 11 fixedly installed at the lower end of the clamp 10, two adjusting rods 9 rotatably installed inside the rear end of the clamp 10, each adjusting rod 9 having a threaded hole 8 at its rear end, a root irrigation rod 7 threadedly fitted inside the threaded hole 8, a sub-tube 6 rotatably connected to the upper end of each of the two root irrigation rods 7 via a bearing, a main tube 4 connected between the front ends of the two sub-tubes 6 via a tee connector 5, and a solenoid valve 3 installed near the front end of the main tube 4;

[0023] The upper end of the waterproof casing 1 of the electrical appliance has a battery compartment 13, and a sealing cover 2 is snapped onto the upper end of the battery compartment 13. A lithium battery is installed inside the battery compartment 13. A controller is embedded inside the waterproof casing 1 of the electrical appliance. The controller is electrically connected to the lithium battery, the soil moisture sensor 11 and the solenoid valve 3. A limit block 12 is fixedly installed on the upper end of the clamp 10. The front end of the main pipe 4 passes through the limit block 12 and leads to the front end of the waterproof casing 1 of the electrical appliance. The main pipe 4 and the sub-pipe 6 are flexible hoses. A water spray hole is opened at the lower end of the root irrigation rod 7. The root irrigation rod 7 is a rigid pipe with threads on its outer surface.

[0024] Specifically, soil moisture sensor 11 monitors soil moisture in real time. When dry soil is detected, solenoid valve 3 automatically opens for irrigation, ensuring that water is directly delivered to the crop roots. This avoids water evaporation and loss as in traditional irrigation methods, greatly improving water resource utilization efficiency. The entire irrigation process is automatically managed by the controller, requiring no manual intervention, reducing farmers' labor intensity and time costs. The coordinated control of soil moisture sensor 11 and solenoid valve 3 ensures the accuracy and timeliness of irrigation, improving work efficiency.

[0025] The device mainly consists of an electrical waterproof casing 1, a clamp 10, an adjusting rod 9, and a root irrigation rod 7. It has a simple structure and is easy to install. The root irrigation rod 7 connects to the adjusting rod 9 via a threaded hole 8, allowing for adjustment of its position and depth according to the needs of different crops, making it highly adaptable. The device is powered by a lithium battery. The soil moisture sensor 11 and the solenoid valve 3 operate intermittently, resulting in low energy consumption. A single AA lithium battery can power the device for an extended period, reducing energy consumption and meeting energy conservation and environmental protection requirements. The spray hole at the lower end of the root irrigation rod 7 is designed for slow overflow, preventing soil clogging and ensuring continuous and efficient irrigation. Direct root irrigation avoids water droplets remaining on leaves or fruits, preventing scorching under direct sunlight, protecting crop health, and improving yield and quality.

[0026] Working principle: During use, the distance between the two adjusting rods 9 is adjusted so that they are positioned on both sides of the crop rootstock. Then, the root irrigation rod 7 is rotated to adjust its length. The root irrigation rod 7 is then inserted into the soil on both sides of the crop rootstock. The soil moisture sensor 11 is then inserted into the soil relatively close to the root irrigation rod 7. One end of the main pipe 4 is connected to a high-level water tank or a pressurized water tank. The solenoid valve 3 is normally closed, while the soil moisture sensor 11 operates intermittently, which can be set to open for 30 seconds to 1 minute every 3-5 hours. When the soil is detected to be dry within 1 minute, the solenoid valve 3 is opened to initiate irrigation. The soil moisture sensor 11 can only be turned off after the solenoid valve 3 is closed when the soil moisture reaches the standard. If no soil dryness is detected within 1 minute, it can be turned off directly. The soil moisture sensor 11 is made of relatively low-precision and inexpensive lithium battery, preferably a 3000 mAh AA battery. One or more batteries can be installed. Taking a 3000 mAh AA lithium battery as an example, the soil moisture sensor 11 consumes 20-50 mAh of power per hour when it is turned on. Moreover, this technology is only turned on intermittently and is in standby mode most of the time. The solenoid valve 3 is only turned on after the soil is detected to be dry. Therefore, one AA lithium battery can make this device work for a very long time.

[0027] The specific usage is as follows: after the soil moisture sensor 11 detects the set soil dryness level, the solenoid valve 3 is opened, and the water flows through the main pipe 4 into the sub-pipe 6, and then into the root irrigation rod 7. The water slowly overflows through the spray hole at the lower end of the root irrigation rod 7. Since the water overflows slowly, the soil is unlikely to clog the spray hole, and the irrigation efficiency will not be affected. Targeted irrigation can be achieved for the roots of crops. When the water overflows to the vicinity of the soil moisture sensor 11, and the soil moisture sensor 11 detects that the humidity meets the data requirements, the solenoid valve 3 is closed. The entire control program is based on the controller. The specific control principle is a relatively common and known technology, so it will not be described in detail here.

[0028] This irrigation technology allows for direct irrigation from the roots of crops, saving water resources and increasing irrigation efficiency. It eliminates the need for manual operation, overcoming the drawbacks of manual irrigation.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
