[0040] The two ends of the bottom end of the displacement plate 3 are slidably connected with anti-slip plates 33, so that one end of the connecting frame 2 is located between the anti-slip plate 33 and the displacement plate 3 through the reverse movement of the two anti-slip plates 33, and the height of the displacement plate 3 is limited. A translation component for driving the anti-slip plate 33 to move is installed inside the displacement plate 3. The translation component includes a displacement sleeve 23, a push rod motor 24, a second worm 25, a limiting plate 26, a synchronization block 27, a second worm gear 30, a second conveying shaft 31 and a threaded segment 32.

[0042] The outer sides of both ends of the second worm 25 are rotatably connected to the limit plates 26, the top of the limit plates 26 is fixed to the displacement plate 3, so as to limit the position of the second worm 25, the bottom of the second worm 25 is meshedly connected to the second worm wheel 30, the inside of the second worm wheel 30 is fixed to the second conveying shaft 31, so that the rotation of the second worm wheel 30 drives the second conveying shaft 31 to rotate;

A synchronization groove 29 is provided inside the displacement sleeve 23. The synchronization groove 29 is slidably connected with the synchronization block 27, so that when the synchronization block 27 is located inside the synchronization groove 29, the rotation of the first conveying shaft 20 drives the displacement sleeve 23 to rotate through the cooperation of the synchronization block 27 and the synchronization groove 29. A rotation groove 28 is provided inside the displacement sleeve 23 and located on one side of the synchronization groove 29, and the synchronization groove 29 is connected with the rotation groove 28. When the synchronization block 27 is located inside the rotation groove 28, the rotation of the first conveying shaft 20 cannot drive the displacement sleeve 23 to rotate.

[0044] The use process of the irrigation device with adjustable flow provided by the utility model is as follows: when it is necessary to adjust the position of the displacement plate 3 on the connecting frame 2 to adjust the position of the spray head 6 for spraying liquids such as nutrient solution, the first conveying shaft 20 is driven to rotate by the rotation of the transmission drive motor 19, so that the rotation of the first conveying shaft 20 drives the first worm 21 to rotate, and the first worm 21 drives the rotating shaft 17 to rotate through the cooperation with the first worm wheel 22, so that the rotating shaft 17 drives the displacement gear 18 to rotate, and the displacement gear 18 is meshed and connected with the connecting frame 2 and the connecting frame 2 is fixed, so that the displacement plate 3 is translated on the top of the connecting frame 2;

[0045] At the same time, before the displacement plate 3 moves, the rotation of the first conveying shaft 20 drives the displacement sleeve 23 to rotate through the synchronous block 27 located inside the synchronous groove 29, and the rotation of the displacement sleeve 23 drives the second worm 25 to rotate synchronously, and the rotation of the second worm 25 drives the meshing second worm gear 30 to rotate, so that the rotation of the second worm gear 30 drives the second conveying shaft 31 to rotate, and the rotation of the second conveying shaft 31 drives the threaded anti-dropping plate 33 to move through the two threaded sections 32 with opposite rotation directions, so that the two anti-dropping plates 33 move away and enter the bottom of the connecting frame 2, at this time, the displacement plate 3 can only translate at the top of the connecting frame 2, and cannot move in height, and then the push rod motor 24 is powered to drive the translation plate to move, so that the translation plate drives the rotationally connected displacement sleeve 23 to move, so that the movement of the displacement sleeve 23 allows the synchronous block 27 to enter the inside of the rotating groove 28 from the inside of the synchronous groove 29, at this time, the rotation of the first conveying shaft 20 can no longer drive the displacement sleeve 23 to rotate through the synchronous block 27, and at this time, the rotation of the first conveying shaft 20 can only drive the displacement gear 18 to rotate;

[0046] When the anti-slip plate 33 needs to be detached from the bottom of the displacement plate 3, the first conveying shaft 20 is rotated while the push rod motor 24 works to drive the translation plate to move, so that the translation plate drives the displacement sleeve 23 to move in the direction close to the transmission drive motor 19. At this time, the synchronization block 27 is constantly in contact with the synchronization groove 29, and the rotation of the synchronization block 27 and the chamfer of the outer side of the synchronization block 27 enter the interior of the synchronization groove 29, and then the rotation of the synchronization groove 29 drives the two anti-slip plates 33 to move closer through the threaded section 32. However, in this embodiment, the anti-slip plate 33 will basically not be removed after the installation is completed.
