Description

Technical Field

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

[0002] Tamarix, a unique plant with both drought and salt tolerance, plays an irreplaceable role in desertification control and saline-alkali land improvement. Since its growing environment is mostly in water-scarce areas, irrigation methods must ensure precise water supply to meet its growth needs while maximizing water conservation, placing stringent requirements on irrigation practices.

[0003] Existing irrigation systems have significant shortcomings in practical applications. Due to the dispersed irrigation areas, a large amount of water is lost through evaporation or seepage before being absorbed by the tamarisk roots, resulting in low water resource utilization. More importantly, this method cannot adjust the water supply according to the differences in tree height, crown width, and other growth characteristics of the tamarisk. A uniform irrigation standard is applied regardless of the size of the plant, often leading to overwatering of individual trees. This not only causes a serious waste of precious water resources but may also damage the physiological characteristics of tamarisk adapted to arid environments due to excessive water, affecting its growth stability in special habitats. This contradicts the core objectives of water conservation and efficiency improvement in desertification control and saline-alkali land improvement. Utility Model Content

[0025] Working principle: When the device is needed, first push the water storage tank 5, and with the help of the pulley 4 with brake pads, move the base 1 to the side of the tamarisk tree that needs irrigation, and lock the brake pads to fix the device; then, according to the height, crown width and other specifications of the tamarisk tree, adjust the position of the adjusting plate 204 inside the water-saving tank 202: rotate the rotating wheel 207, the rotating wheel 207 drives the threaded rod 206 to rotate inside the U-shaped frame 205, the threaded rod 206 drives the movable plate 209 to slide along the vertical groove 208, and the movable plate 209 drives the adjusting plate 204 to rise and fall inside the water-saving tank 202 through the connecting rod 210; observe the adjusting plate 204 through the observation window 203. When the water level corresponding to scale 04 is reached and the appropriate water volume for the tamarisk tree is achieved, the rotating wheel 207 stops rotating, and the threaded rod 206 self-locks the position of the adjusting plate 204. Then, the first extraction pump 211 is started via the PLC controller 7. The first extraction pump 211 draws water from the storage tank 5 through the first extraction pipe 213 and delivers it to the water-saving tank 202 via the first discharge pipe 212. When the water level in the water-saving tank 202 rises to the bottom of the adjusting plate 204, after confirmation through the observation window 203, the PLC controller 7 is operated to shut off the first extraction pump 211. At this point, the water volume in the water-saving tank 202 is the preset irrigation amount. Next, connect the second discharge pipe 11 to the external irrigation hose and nozzle. The operator holds the nozzle and aims it at the tamarisk root area. Then, the second extraction pump 9 is started through the PLC controller 7. The second extraction pump 9 draws water from the water-saving tank 202 through the second extraction pipe 10, and delivers it to the nozzle through the second discharge pipe 11 and irrigation hose. Finally, it is accurately sprayed onto the tamarisk root area to complete the irrigation operation. If it is necessary to irrigate with a mixture of pesticide and water, first install the filter device 3: place the mounting plate 302 with filter screen 303 into the mounting groove 301 of the square mounting base 8, and slide the convex plate 305 to move it along the sliding groove 304. The device moves, causing the insertion rod 306 to be inserted into the insertion hole 307, thus initially fixing the mounting plate 302. Then, the bolts 309 on the surface of the extension plate 308 are screwed into the threaded hole 310 on the top of the protruding plate 305, so that the mounting plate 302 is firmly fixed. At this time, the mixture is poured into the water storage tank 5. The filter screen 303 can filter out undissolved pesticide clumps to avoid subsequent pipe or pump blockage. The filtered liquid can be used for irrigation according to the above steps. After irrigation is completed, the second extraction pump 9 is turned off, the connection between the irrigation hose and the second discharge pipe 11 is disconnected, and the device is pushed to the next tamarisk tree. The above operation is repeated.
