Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural drip irrigation, and particularly relates to a drip irrigation system with humidity detection. Background Technique

[0002] A drip irrigation system is an efficient and precise irrigation method. It slowly and evenly drips water in the form of water droplets into the soil near the roots of plants through a pipeline network. A drip irrigation system usually consists of a water source, a head hub, a water delivery and distribution pipeline network, and drip heads. The water source provides irrigation water. The head hub filters, pressurizes, and adds fertilizers to the water. The water delivery and distribution pipeline network transports the treated water to each drip head. The drip head is a key component of the drip irrigation system, which can control the water flow rate and drip irrigation speed to ensure that each plant can obtain an appropriate amount of water and nutrients. The drip irrigation system has many advantages such as water saving, energy saving, labor saving, and improving crop yield and quality, and is widely used in agriculture, horticulture and other fields;

[0003] A Chinese patent with the publication number "CN218353795U" discloses a drip irrigation device, which includes a water tank. An adjusting device is arranged on the arc surface of the water tank. The adjusting device includes a communicating pipe. One end of the communicating pipe is communicated with the arc surface of the water tank. The other end of the communicating pipe is a closed end. A water valve is arranged on the arc surface of the communicating pipe. A branch pipe is communicated with the arc surface of the communicating pipe away from the water tank. A ring pipe is communicated with the arc surface of the branch pipe. A plurality of drip irrigation heads are arranged on the arc surface of the ring pipe. The plurality of drip irrigation heads are evenly distributed in a circumferential circle on the same side arc surface of the ring pipe. The utility model improves the practicability of the drip irrigation device, enables the roots of fruit trees to receive uniform water and fertilizers during drip irrigation, thus facilitating the growth of fruit trees, and to a certain extent improves the drip irrigation efficiency of the drip irrigation device and the yield of fruit trees;

[0004] During the use of the above device, although it can assist in realizing circular drip irrigation, in the specific use process, there are obvious defects and deficiencies. First of all, it is not easy to quickly disassemble and assemble the circular pipes of each drip irrigation as a whole, and the operation process is relatively cumbersome and complex. Secondly, it is impossible to conveniently expand the drip irrigation range during its use, and it can only perform drip irrigation on a single plant. This limitation is obviously difficult to adapt to the needs of large-scale agricultural planting. Moreover, it lacks the corresponding humidity detection function and cannot detect the soil humidity in real time, which is extremely likely to cause the situation of excessive or insufficient soil humidity. At the same time, in large-scale farmland, if large-area crops need to be drip-irrigated, the efficiency of this device will be extremely low. Due to the inconvenience of disassembling and assembling the circular pipes, it will consume a lot of time and manpower. Moreover, its narrow drip irrigation range requires a large number of devices to be arranged to meet the needs, which not only increases the cost but also increases the management difficulty. Therefore, in order to better meet the needs of actual agricultural production, it is imperative to improve this device. Summary of the Utility Model

The docking head 72 is fixedly installed at the inner end of the connecting pipe 61. The inner ends of the limit components 74 are clamped with the docking head 72. The side rails 91 are fixed in the middle of one side of the mounting ring 3. The driving motor 92 at the bottom drives the lead screw 93 to rotate inside the side rails 91, so that the threadedly connected slider 94 can drive the annular pipe 4 to rise and fall, realizing flexible adjustment of the drip irrigation height to adapt to different plants. The quick connector 7 is ingeniously designed. The solenoid valves 71 at equal intervals on the outer side of the annular pipe 4 cooperate with the socket joint 73, the docking head 72 at the inner end of the connecting pipe 61 and the limit components 74 on both sides, which can quickly achieve stable connection and disassembly, facilitating installation and maintenance. This design improves the convenience and efficiency of the device, makes the drip irrigation system more intelligent and practical, reduces the operation difficulty and labor cost, and ensures the accuracy and stability of drip irrigation.

[0029] Reference Figure 3 , the limit component 74 includes a fixed rail 741 and a card slot 742. The fixed rails 741 are fixedly installed on both sides of the socket joint 73. A limit spring 743 is fixedly connected inside the fixed rails 741. A limit block 744 is fixedly installed at the end of the limit spring 743. The card slots 742 are opened on both sides of the docking head 72. The inner end of the limit block 744 penetrates through the sleeve pipe and is inserted into the inside of the card slot 742. The outer side of the limit block 744 is fixedly connected with a connecting shaft 745.

A push plate 747 is fixedly installed at the outer end of the adjusting connecting rod 746. The fixed rails 741 on both sides of the socket joint 73 are provided with limit springs 743, which push the limit blocks 744, so that the inner ends of the limit blocks 744 pass through the sleeve pipe and are inserted into the card slots 742 on both sides of the docking head 72 to achieve stable connection. The connecting shaft 745 connects the limit block 744 with the outer adjusting connecting rod 746. The push plate 747 at the outer end of the adjusting connecting rod 746 is convenient for operation. This design makes the connection firm and reliable, not easy to loosen, ensuring the normal operation of the drip irrigation system. When disassembly is required, by pushing the push plate 747 to drive the connecting shaft 745 and the limit block 744 to move, separation can be easily achieved. The operation is simple and fast. Whether it is installation or disassembly, it can be completed quickly, improving work efficiency and reducing the time cost of maintenance and adjustment.

[0030] Principle and advantages of use: By setting the lifting mechanism 9, the device can be operated by starting the driving motor 92 during use. When the driving motor 92 is running, it will drive the screw rod 93 to rotate. With the help of the rotation of the screw rod 93, the slider 94 can be assisted to slide up and down on the inner side of the side rail 91. As the slider 94 slides up and down, the annular tube 4 can be driven to move up and down. Through the up and down displacement of the annular tube 4, the height of each drip irrigation mechanism 6 can be flexibly adjusted. In this way, when the device is used for drip irrigation of different plants, it can be flexibly adapted to meet diverse needs. For example, when facing taller plants, the drip irrigation mechanism 6 can be raised to ensure that water droplets can accurately drip onto the roots of the plants; and for shorter plants, the height of the drip irrigation mechanism 6 can be correspondingly lowered to avoid waste of water resources and unnecessary infiltration.

[0031] By providing a quick-install structure, the device can be used to insert the docking joint 72 into the interior of the sleeve joint 73. When the docking joint 72 and the sleeve joint 73 are connected to each other, the limiting spring 743 can drive the limiting block 744 to be inserted into the inner side of the slot 742. Since the slot 742 and the limiting block 744 are mutually engaged and limited, the docking joint 72 and the sleeve joint 73 can be connected and installed. When the docking joint 72 and the sleeve joint 73 need to be disassembled, it is only necessary to push the push plate 747 to drive the connecting shaft 745 to move outward, and the outward movement of the connecting shaft 745 can drive the limiting block 744 to move outward and disengage from the inner side of the slot 742. The stopper 744 and the card slot 742 are separated from each other, and the butt joint 72 and the sleeve joint 73 are separated from each other. When installation is required, the butt joint 72 and the sleeve joint 73 only need to be connected to each other, and the limit spring 743 is pressed against the stopper 744 to be inserted into the card slot 742. It can be seen that the device as a whole can quickly card and separate the drip irrigation mechanism 6, and its use, operation and installation are relatively convenient. This quick-installation structure greatly improves the use efficiency of the device. In practical applications, for example, when a drip irrigation mechanism 6 needs to be replaced or repaired, it can be quickly disassembled and installed, saving a lot of time and manpower.

[0032] By setting up the drip irrigation mechanism 6, during the use of this device, connecting pipes 61 of different lengths can be prepared according to actual needs, enabling it to adapt to the drip irrigation requirements of different planting spacings. Moreover, during the drip irrigation process, a circular drip irrigation loop pipe 62 is provided. The drip irrigation loop pipe 62, in cooperation with the drip irrigation joints, can evenly drip water solution to the roots of the vegetation. At the same time, during the drip irrigation, by adjusting the sliding of the sliding rod 643 inside the sleeve 641, the anti-slip foot pads 644 can be adjusted to fit the ground, and the hand-twist type screw rod 645 is used to assist in fixing the sliding rod 643, enabling this device to quickly adapt according to the height during use, being able to assist in supporting the connecting pipe 61, thereby improving its overall stability. Additionally, during use, the telescopic spring 647 can reset to drive the humidity sensor 648 to fit the ground, enabling this device to detect the humidity of the ground soil in real time during use, enabling this device to precisely adjust the drip irrigation humidity, making the soil humidity within the optimal adaptation range, which can improve the overall use convenience and drip irrigation accuracy of this device. For example, in large-scale farmland planting, the planting spacings in different areas may vary. By preparing connecting pipes 61 of different lengths, it can ensure that each area can receive uniform and effective drip irrigation, and the function of real-time detecting soil humidity can adjust the drip irrigation amount in a timely manner according to the actual situation, ensuring that the soil always maintains the humidity state most conducive to plant growth.
