Description

Technical Field

[0001] This utility model relates to the field of agricultural engineering technology, specifically to a drip irrigation device for organic vegetable cultivation. Background Technology

[0002] Organic vegetables refer to vegetables produced in strict accordance with organic production procedures. To facilitate the control of growth conditions, organic vegetables are often grown in greenhouses. Currently, drip irrigation systems are commonly used to supplement the water supply for organic vegetables grown in greenhouses.

[0003] Existing drip irrigation systems typically consist of four main parts: water source engineering, headworks, water distribution network, and drippers. These parts work together to achieve precise irrigation.

[0004] In current drip irrigation technology, dripper clogging is a key issue restricting irrigation efficiency. When irrigation water is not adequately filtered or has a high impurity content, pollutants such as silt, organic debris, and microbial flocs can easily enter the drip irrigation system with the water flow. These impurities continuously deposit and accumulate in the water distribution network, eventually clogging the narrow water outlet channels of the drippers, leading to poor water flow or even water interruption, which seriously affects the water supply and growth quality of crops. To address these issues, a drip irrigation device for organic vegetable cultivation is proposed. Utility Model Content

[0005] In order to solve the above problems, the purpose of this utility model is to provide a drip irrigation device for organic vegetable cultivation.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: it includes a sleeve and a sewage discharge assembly at the end of the sleeve. The bottom of the sleeve is provided with an inlet and an outlet. A coarse filter screen is provided at the end of the inner cavity of the sleeve near the inlet, and a fine filter screen is provided at the end of the inner cavity of the sleeve near the outlet.

[0007] Preferably, the sewage discharge assembly is provided with a fixed frame near the outlet end, a servo motor is provided on one side of the fixed frame, a drive rod is provided at the output end of the servo motor, the drive rod extends through the fixed frame into the inner cavity of the sleeve, a sewage discharge pipe is provided at the end of the surface of the drive rod near the outlet, and a plurality of sewage suction devices are sleeved on the surface of the sewage discharge pipe.

[0008] Preferably, a U-shaped fixing frame is provided at the center of the fixing frame, and a threaded button is provided between the U-shaped fixing frames. A threaded groove is provided on the surface of the drive rod near one end of the U-shaped fixing frame, and the threaded groove on the surface of the drive rod is adapted to the threaded protrusion on the inner sidewall of the threaded button.

[0009] Preferably, the surface of the vacuum cleaner is provided with a long suction port, which is in contact with the inner wall of the fine filter screen.

[0010] Preferably, the drain pipe can slide on the surface of the drive rod.

[0011] Preferably, a drain outlet is provided at the top of the sleeve near the drain assembly.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: By adopting a graded filtration structure of coarse and fine filters inside the sleeve, a double protective barrier is formed. The water flowing in from the inlet first passes through the coarse filter to intercept large particles of impurities such as mud, dead branches, and aquatic plants, reducing the pressure on subsequent filtration. The water that has undergone preliminary filtration continues to flow towards the outlet, where the fine filter further intercepts tiny impurities such as microbial remains and colloidal particles. This filtration method can effectively cover pollutants of different particle sizes, improve the water purification accuracy by more than 30%, ensure that the irrigation water meets the cleanliness standards of the drip irrigation system, and significantly reduce the risk of dripper clogging.

[0019] 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.

[0020] Example: Figures 1-4As shown, this utility model provides a drip irrigation device for organic vegetable planting, including a sleeve 1 and a sewage discharge component 2 at the end of the sleeve 1. The bottom of the sleeve 1 is provided with an inlet 101 and an outlet 102. A coarse filter screen 104 is provided at the end of the inner cavity of the sleeve 1 near the inlet 101, and a fine filter screen 105 is provided at the end of the inner cavity of the sleeve 1 near the outlet 102. When working, the motor starts to provide flow power for the well water. The well water is drawn into the sleeve 1 from the inlet 101. The water flow first passes through the coarse filter screen 104, which has a large mesh diameter. Its main function is to filter out large particulate impurities in the well water. This step can effectively reduce the burden of subsequent fine filtration and avoid the fine filter screen being blocked by large particles. The water that has passed through the coarse filter flows to the other end and enters the area of ​​the fine filter screen 105. The mesh of the fine filter screen is more compact and can further intercept small suspended solids, microbial debris and other tiny impurities in the water, so that the water quality meets the cleanliness requirements of the drip irrigation system and avoids the drip irrigation hole from being blocked.A mounting bracket 201 is installed at one end of the sleeve 1 near the outlet 102 to fix the servo motor 202. The servo motor 202 provides the power source, and its output end is connected to the drive rod 203. The drive rod 203 passes through the mounting bracket 201 and extends into the inner cavity of the sleeve 1. The drain pipe 204 is sleeved on the drive rod 203, and multiple suction devices 205 are distributed on its surface. The suction devices 205 are in close contact with the surface of the fine filter screen 105 to adsorb impurities. When the servo motor 202 is powered on, its output shaft drives the drive rod 203 to rotate. Since the drive rod passes through the mounting bracket and is rigidly connected to the drain pipe 204, the drain pipe rotates synchronously with the drive rod. When the drain pipe 204 rotates, the suction devices 205 on its surface move in a circular motion around the fine filter screen 105. A U-shaped mounting bracket 206 is installed at the center of the mounting bracket to fix the threaded button 207. The threaded button 207 is a hollow cylinder with threaded protrusions on its inner wall. Between the U-shaped fixing brackets, the axis coincides with the drive rod 203. When the servo motor 202 drives the drive rod 203 to rotate, the threaded button 207 cannot rotate because it is fixed by the U-shaped fixing bracket 206. The threaded groove of the drive rod meshes with the threaded protrusion of the threaded button, forming a helical transmission. The servo motor can drive the drain pipe 204 and the vacuum cleaner 205 to rotate and move linearly around the sleeve axis. The movement trajectory of the vacuum cleaner 205 is a spiral line, which can cover the entire surface of the fine filter screen 105. The linear movement does not require an additional motor. It only converts the rotational power into linear power through the mechanical cooperation between the threaded button and the drive rod, simplifying the structure and reducing energy consumption. The long suction port on the surface of the vacuum cleaner 205 fits tightly against the inner wall of the fine filter screen 105. When the suction... When the cleaner 205 moves in a spiral motion on the filter screen surface, the long suction port uses negative pressure adsorption to suck in impurities such as mud, microbial debris, and colloids adhering to the filter screen surface. The drain port 103 at the top of the sleeve 1, near the drain assembly 2, is the outlet for the entire drain process. After the cleaner 205 finishes cleaning the fine filter screen 105, the impurities flow towards the drain port through the drain pipe. When the control valve of the drain port 103 is opened, under the action of negative pressure or water flow in the drain pipe, the impurities collected in the pipe are discharged out of the sleeve through the drain port, completing one complete drain process.

[0021] By adopting the above technical solution.

[0022] Obviously, those skilled in the art of agricultural engineering can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
