Abstract
Description
Technical Field
[0001] This utility model relates to the field of corn planting technology, specifically to a low-temperature resistant corn planting water and fertilizer integrated fertilization device. Background Technology
[0002] Cold-resistant corn refers to corn varieties that can grow and develop normally in low-temperature environments. These varieties typically have strong cold resistance, maintaining normal physiological functions and growth under low-temperature conditions, thus ensuring high yield and quality. Corn requires periodic watering and fertilization during its growth process. Large-scale planting often employs integrated water and fertilizer management, which saves water and ensures comprehensive and precise fertilization. Therefore, integrated water and fertilizer tanks offer significant advantages for corn cultivation. Fertilizer ratios can be flexibly adjusted according to different growth needs. Furthermore, irrigation equipment requires high water cleanliness; excessive impurities can cause pipe blockages and affect irrigation, necessitating water filtration.
[0003] After a period of use, the filter screen needs to be cleaned and repaired. When the filter screen needs to be cleaned or repaired, it requires maintenance personnel to perform more complicated procedures or reinstall it, which greatly increases the workload of maintenance personnel.
[0004] Therefore, we propose a water and fertilizer integrated fertilization device for low-temperature resistant corn cultivation. Utility Model Content

A fixing pin 313 is integrally connected to one side of the sealing sleeve 304. The fixing pin 313 is fixedly installed through the fixing hole 307 and the locking hole 314. When replacing the filter screen 306 by setting the filter assembly 3, turn the knob 309 to rotate the rotating ring 308, align the wider end of the locking hole 314 with the fixing hole 307, pull out the fixing pin 313, remove the sealing sleeve 304, remove the arc-shaped sealing plate 305, and collect the collection. Remove the filter screen 306 and replace it. After replacement, cover the placement groove 303 with the arc-shaped sealing plate 305, move the sealing sleeve 304 so that the fixing pin 313 is inserted into the fixing hole 307, release the dial 309, and under the action of the return spring 312, the rotating ring 308 reverses, thereby locking the narrower end of the locking hole 314 with the fixing pin 313, which facilitates the replacement of the filter screen 306. While facilitating the disassembly and assembly of the filter screen 306, it also avoids setting too many structures inside the liquid inlet pipe 301.
[0024] Both ends of the inlet pipe 301 are fixedly installed opposite to the middle of the water inlet pipe 2 and the connecting conduit 7, respectively. A sealing ring 317 is integrally formed inside the inlet pipe 301, located on both sides of the placement groove 303.
