Description

Technical Field

[0001] This utility model belongs to the field of soil irrigation technology, specifically relating to a soil moisture sensing irrigation device. Background Technology

[0002] With the development of modern agricultural technology, intelligent irrigation systems have gradually become the core equipment for farmland management due to their water-saving and high-efficiency characteristics. Among them, the accuracy and stability of soil moisture detection directly affect the rationality of irrigation decisions. At present, most common soil moisture sensing irrigation devices adopt an insertion probe structure, which realizes moisture sensing by contacting the probe with the soil.

[0003] However, such devices have the following problems in practical applications: 1. The devices are mostly fixed with a single column or simple support, which makes them prone to tipping over in strong winds or loose soil, requiring frequent manual adjustment or reinforcement, affecting the stability and effectiveness of the device; 2. For compacted soil or complex geological conditions, the probe drill bit is prone to wear after long-term use, resulting in increased penetration resistance and insufficient detection depth. Since the probe drill bit adopts a fixed structure, it needs to be completely disassembled when replacing it, which is time-consuming and labor-intensive, limiting the service life of the device; 3. The position of the humidity sensor is usually fixed, making it difficult to flexibly adjust according to different soil layers and crop root distribution characteristics, affecting detection accuracy and irrigation effect. Utility Model Content

[0004] In view of the shortcomings of existing technologies, a soil moisture sensing irrigation device is proposed to solve the technical problems of easy tipping in strong winds or loose soil, and difficulty in replacing worn drill bits in compacted soil or complex geological conditions.

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

[0006] A soil moisture sensing irrigation device includes a sleeve, a moisture sensor, and a drill bit. A soil penetration component is disposed inside the sleeve, and a support component is disposed outside the sleeve. The moisture sensor is disposed inside the soil penetration component, and the distance between the moisture sensor and the sleeve is adjustable. The drill bit is detachably disposed at the end of the soil penetration component.

[0010] The technical solution is further configured such that a groove is provided on the side of the support block, and a baffle that can slide relative to it is provided inside the groove;

[0011] During the sliding process of the baffle relative to the groove, the baffle can block or open the insertion hole.

[0012] The technical solution is further configured such that the soil penetration component includes a first screw, the first screw passes through the sleeve and is threadedly connected to the sleeve, the humidity sensor is disposed on the first screw, and the drill bit is detachably connected to the bottom of the first screw.

[0013] The technical solution is further configured such that a protective component is provided on the first screw, and the humidity sensor is disposed inside the protective component.

[0014] The technical solution is further configured such that the protective component includes two protective covers, which are arranged opposite to each other to form a cavity for accommodating the humidity sensor.

Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0029] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0030] Example 1

[0031] According to an embodiment of this utility model, a soil moisture sensing irrigation device is provided. Please refer to [link / reference]. Figure 1 The device includes a sleeve 100, a humidity sensor, and a drill bit 500. A soil penetration component 300 is disposed inside the sleeve 100, and a support component 200 is disposed outside the sleeve 100. The humidity sensor is disposed inside the soil penetration component 300, and the distance between the humidity sensor and the sleeve 100 is adjustable. The drill bit 500 is detachably disposed at the end of the soil penetration component 300.

[0032] Furthermore, the sleeve 100 is cylindrical or prismatic in shape and made of stainless steel, possessing sufficient strength and corrosion resistance.

[0033] Furthermore, the humidity sensor is a resistive soil moisture sensor with a measurement range of 0-100% relative humidity, an accuracy of ±3%, and a response time of less than 2 seconds. Preferably, the humidity sensor model is VH400.

[0034] In use, the humidity sensor is manually rotated and positioned inside the soil using the soil penetration component 300, so that the bottom of the sleeve 100 contacts the soil surface. This allows the soil penetration component 300 to automatically break up compacted soil as it rotates and presses down, facilitating the detection of soil moisture in different geological conditions. Furthermore, the depth of the humidity sensor can be flexibly adjusted using the soil penetration component 300, allowing for the detection of soil moisture at different depths. The support component 200 improves the stability between the sleeve 100 and the soil, reducing the risk of tipping over in strong winds or loose soil conditions, and decreasing the frequency of manual adjustments or reinforcement. The drill bit 500 is detachably connected to the soil penetration component 300, allowing for quick replacement of worn drill bits and extending the overall lifespan of the device.

[0035] In the soil moisture sensing irrigation device of this embodiment, please refer to... Figures 1 to 4 The support assembly 200 includes a support arm 201 and a support block 202. The first end of the support arm 201 is connected to the sleeve 100, and the second end of the support arm 201 is connected to the support block 202. The bottom surface of the support block 202 is in contact with the soil.

[0036] Furthermore, the support arm 201 is made of aluminum alloy, which has good strength and lightweight characteristics. The bottom surface of the support block 202 is designed with a rough texture to increase its friction with the soil and improve stability.

[0037] Furthermore, multiple support components 200 are evenly distributed around the sleeve 100 in a circumferential manner, providing multi-point support for the sleeve 100. Preferably, three support components 200 are provided to form a stable triangular support structure.

[0038] Specifically, the first end of the support arm 201 is provided with a connecting seat 206 that is hinged thereto, allowing the support arm 201 to rotate and adjust its angle in a vertical plane to adapt to different terrain conditions. The connecting seat 206 is disposed on the insert block 208, which is inserted into a slot on the sleeve 100, thereby realizing a detachable connection between the connecting seat 206 and the sleeve 100.

[0039] In the soil moisture sensing irrigation device of this embodiment, please refer to... Figures 1 to 4 The second end of the support arm 201 is provided with a fixing plate 205. A connecting rod 209 is provided between the fixing plate 205 and the support block 202. A counterweight 203 is provided on the connecting rod 209 and slidably connected thereto. An insertion rod 207 is provided on the counterweight 203. An insertion hole for the insertion rod 207 to pass through is provided on the support block 202.

[0040] Furthermore, the counterweight 203 is made of cast iron and has a central hole, allowing it to slide along the connecting rod 209.

[0041] In use, the counterweight 203 moves downward under its own weight, and the insertion rod 207 moves along with the counterweight 203, allowing the insertion rod 207 to be inserted into the soil through the insertion hole without the need for additional tools or complicated operations. The insertion method is relatively gentle, which can maintain the original porosity and compactness of the soil. At the same time, under the gravity of the counterweight 203, the insertion rod 207 can maintain a relatively stable state after being inserted into the soil, and is not easily shaken or displaced by slight external vibrations, wind, or other factors. This helps to ensure the stability of the humidity sensor, making the detection data more reliable and reducing measurement errors caused by the instability of the insertion rod 207.

[0042] In the soil moisture sensing irrigation device of this embodiment, please refer to... Figures 1 to 4 The support block 202 has a groove on its side, and a baffle 204 that can slide relative to it is provided inside the groove;

[0043] During the sliding process of the baffle 204 relative to the groove, the baffle 204 can block or open the insertion hole.

[0044] Furthermore, the size of the baffle 204 is slightly smaller than the size of the groove, ensuring that the baffle 204 can slide freely within the groove. When the baffle 204 slides to the position of blocking the socket, the plug rod 207 cannot be inserted into the socket; when the baffle 204 slides to the position of opening the socket, the plug rod 207 can be inserted into the socket.

[0045] When the support component 200 is removed from the soil, the counterweight 203 is moved upward to separate the insertion rod 207 from the soil, and the baffle 204 is slidably engaged in the groove. The baffle 204 can support the bottom of the insertion rod 207. Finally, the insertion block 208 is moved out of the slot, which can separate the support component 200 from the sleeve 100. The operation is convenient and does not require the assistance of tools.

[0046] In the soil moisture sensing irrigation device of this embodiment, please refer to... Figures 1 to 5 The soil penetration component 300 includes a first screw 301 that passes through the sleeve 100 and is threadedly connected to the sleeve 100. The humidity sensor is disposed on the first screw 301, and the drill bit 500 is detachably connected to the bottom of the first screw 301.

[0047] Furthermore, the surface of the first screw 301 is treated with rust prevention, and a handle is provided on its top for easy rotation and adjustment by the operator.

[0048] Furthermore, the inner wall of the sleeve 100 is provided with an internal thread that matches the surface thread of the first screw 301, or the sleeve 100 is provided with a threaded sleeve, the inner wall of which is provided with an internal thread that matches the surface thread of the first screw 301.

[0049] In the soil moisture sensing irrigation device of this embodiment, please refer to... Figures 1 to 5 The first screw 301 is provided with a protective component 400, and the humidity sensor is located inside the protective component 400, which effectively protects the humidity sensor from soil impurities and mechanical damage. At the same time, by adjusting the first screw 301, the detection depth can be precisely controlled to adapt to the humidity monitoring needs of different crop root distribution depths, thereby improving the accuracy of irrigation decisions and the efficiency of water resource utilization.

[0050] Furthermore, the protective assembly 400 includes two protective covers 401, which are configured as frustums. The two protective covers 401 are arranged opposite each other and connected by a support rod to form a cavity for accommodating the humidity sensor, which can both protect the humidity sensor from damage and allow soil moisture to pass through.

[0051] In the soil moisture sensing irrigation device of this embodiment, please refer to... Figures 1 to 5 The protective component 400 is located above the drill bit 500, and the drill bit 500 is threadedly connected to the protective component 400 via a second screw 800.

[0052] Furthermore, the drill bit 500 is made of high-hardness alloy steel and is helical in shape, providing excellent penetration performance. The surface of the drill bit 500 is hardened to ensure it is not easily worn when penetrating various soil types. The detachable design of the drill bit 500 facilitates the replacement of different types to adapt to varying soil conditions.

[0053] Specifically, a threaded seat is fixedly installed at the bottom of the protective component 400, and the bottom of the second screw 800 is connected to the drill bit 500. The threaded seat is threadedly connected to the second screw 800, which enables the protective component 400 and the drill bit 500 to be assembled quickly.

[0054] In the soil moisture sensing irrigation device of this embodiment, please refer to... Figures 1 to 2 A support frame 700 is provided above the sleeve 100, and an irrigation component 600 is provided on the support frame 700.

[0055] Furthermore, the irrigation component 600 comprises an injection pipe 601, an annular connecting pipe 602, and an outlet pipe 603. The annular connecting pipe 602 surrounds the soil penetration component 300, and the support frame 700 supports and fixes the annular connecting pipe 602. The outlet pipe 603 is provided with an outlet hole. When the humidity sensor detects that the soil moisture is lower than a preset threshold, the water pump is activated to quickly pump water into the injection pipe 601 and then into the annular connecting pipe 602. Finally, the water required for irrigation flows out through the outlet pipe 603, thereby irrigating the soil. This precise irrigation based on the actual soil moisture avoids the water waste problem in traditional irrigation methods, improves irrigation efficiency and crop growth environment, and has broad application prospects.
