Technical Field

[0001] The utility model relates to the technical field of agricultural production, in particular to a double-channel anti-blocking drip irrigation tape. Background Art

[0002] Drip irrigation is an irrigation method that, according to the water requirements of crops, through pipes and emitters installed on the capillary tubes, drops water, moisture, and nutrients required by the crops drop by drop, evenly and slowly into the root zone soil of the crops. Drip irrigation does not damage the soil structure and can keep the water, fertilizer, and air inside the soil in a good condition suitable for crop growth. Moreover, the evaporation loss is small, there is no surface runoff, and there is no deep leakage. It is a water-saving irrigation method. With the development of drip irrigation technology, ordinary drip irrigation tapes can no longer meet the needs of productivity, so double-channel drip irrigation tapes have emerged.

[0003] The double-channel drip irrigation tape is a special drip irrigation product with two independent channels. The design of this drip irrigation tape allows farmers to provide water and nutrients through the two channels respectively according to the needs of the crops, so as to achieve more precise irrigation management. And farmers can better control the concentration and pH value of the nutrient solution, as well as the water flow rate, thereby improving the growth quality and yield of the crops. Therefore, it is commonly used in crop planting that requires precise control of water and nutrient supply.

[0004] The existing double-channel drip irrigation tape can soften the water quality through a pre-mounted filter and filter impurities in the drip irrigation liquid, but it cannot remind the user whether the filtering device needs to be cleaned, resulting in a reduction in the filtering effect, clogging of the drip heads, a decrease in work efficiency, and economic losses. Summary of the Utility Model

A filter box 3 is arranged on the outer wall of the first thread 18 and the inner end of the filter box 3 is fixedly connected with a first sealing ring 21. This design enables the drip irrigation belt to effectively prevent blockage during use, and at the same time maintains the balance of water pressure through the pressure control device 2, thereby improving the irrigation efficiency and effect. The baffle 14 can rotate along the second rotating shaft 13 with the flow of water.

[0035] Please refer to the attachedFigure 4 - Attachment Figure 6 , the pressure control device 2 includes a main pipe 201. The inner wall of the main pipe 201 is communicated with the inner wall of the connecting pipe 1. A bypass pipe 202 is fixedly connected to the outer wall of the main pipe 201. A drain pipe 208 is communicated with the inner wall of the main pipe 201. An inlet pipe 209 is fixedly connected to the outer wall of the drain pipe 208.

A sliding disk 204 is arranged on the outer wall of the second fixing rod 206. The inner wall of the sliding disk 204 is slidably connected to the outer wall of the second fixing rod 206. A first spring 207 is fixedly connected to the rear side of the sliding disk 204. A limiting block 205 is fixedly connected to the front end of the second fixing rod 206. The outer wall of the sliding disk 204 is attached to the rear end of the inlet pipe 209. The rear end of the first spring 207 is fixedly connected to the outer wall of the first fixing rod 203;

[0036] Specifically, a first spring 207 is fixedly connected to the rear side of the sliding disk 204.

An inlet pipe 209 is fixedly connected to the outer wall of the drain pipe 208. The inlet pipe 209 is responsible for introducing new fluid into the drain pipe 208.

[0037] Please refer to Attachment Figure 3 - Attachment Figure 5 , please refer to Attachment Figure 1 - Attachment Figure 3 , on the inner wall of the detection pipe 6, a second thread 19 is provided. A first thread 18 is arranged on the inner wall of the second thread 19. A second sealing ring 22 is fixedly connected to the outer end of the hollow outer shell 23. At the bottom of the inner walls of the main pipe 201 and the bypass pipe 202, a drip head 15 is communicated. A plurality of drip heads 15 are all communicated at the same horizontal height. An indicating block 17 is fixedly connected to the outer wall of the moving rod 8. A plurality of scale lines 20 are fixedly connected to the inner wall of the chute 5 near the edge. A filter plate 4 is fixedly connected to the inner wall of the filter box 3. Anti-slip patterns 16 are provided on the outer wall of the filter box 3;

[0038] Specifically, the filter plate 4 is to ensure the cleanliness of the liquid when passing through. Anti-slip patterns 16 are also provided on the outer wall of the filter box 3, which enables the filter box 3 to be held more firmly during use. A plurality of drip heads 15 being at the same horizontal height ensures the uniformity during drip irrigation. The second sealing ring 22 enhances the sealing performance of the hollow outer shell 23. The scale lines 20 help to accurately measure the pressure of the incoming water.

[0039] Working principle: When using this drip irrigation tape for drip irrigation, water will pass through the filter box 3 and be filtered by the filter plate 4 and the filter material inside it, and then enter the detection tube 6 to push the baffle 14, causing it to rotate along the second rotating shaft 13, and drive the moving rod 8 fixed on the second rotating shaft 13 to rotate together, causing the first rotating shaft 10 to pull the second spring 12 to slide in the hollow column 9, and the indicating block 17 indicates the value on the scale line 20. When there is dirt accumulation in the filter material in the filter box 3 after long-term use, the water pressure passing through it will become smaller, and the amplitude of pushing the baffle 14 will also become smaller, so that the reading on the scale line 20 indicated by the indicating block 17 becomes smaller to remind the user to replace or clean the filter device;

[0040] First, connect the left connecting pipe 1 to the main pipe 201 and the right connecting pipe 1 to the bypass pipe 202. When the water pressure in the main pipe 201 is too high, the water supply to the bypass pipe 202 is closed, so that the water in the main pipe 201 squeezes the sliding disk 204, compresses the first spring 207, and makes it slide along the second fixed rod 206, and the water is released from the main pipe 201 to the bypass pipe 202 for drip irrigation.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
