[0029] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0030] Refer to Figures 1-5The utility model provides an embodiment: a kind of water distribution drip irrigation device for smart farm greenhouse, including conveying pipe 1, the upper end of the outer wall of conveying pipe 1 is uniformly connected with multiple positioning rods 11, the upper end of multiple positioning rods 11 is uniformly connected with connecting disc 12, the inner wall of connecting disc 12 is all rotatably connected with rotating rod 13, the lower end of rotating rod 13 outer wall is all set with external thread 16, the upper end of the outer wall of conveying pipe 1 is all connected with sliding sleeve 2 slidingly, the lower end of sliding sleeve 2 is all fixedly connected with connecting rod 21, connecting rod 21 lower end is fixedly connected with movable plug 22, the inner wall of sliding sleeve 2 upper end is all set with internal thread 24.

[0031] Compared with prior art water distribution drip irrigation device for smart farm greenhouse, when the water distribution drip irrigation device for smart farm greenhouse is used, rotating knob 14 drives rotating rod 13 to rotate and sliding sleeve 2 to move, sliding sleeve 2 moves to drive limiting block 23 to slide in positioning rod 11, thereby limiting sliding sleeve 2 to move horizontally, movable plug 22 is adjusted in height, thereby indirectly adjusting the flow of liquid into drip head 3, and the flow is adjusted according to the required water amount of different plants.

[0032] The upper end of rotating rod 13 is fixedly connected with knob 14, which facilitates the rotation of rotating rod 13, the upper end of rotating rod 13 outer wall is fixedly connected with limiting ring 15, limiting ring 15 is rotatably connected with the inner wall of connecting disc 12, limiting ring 15 is rotatably connected with the inner wall of connecting disc 12, which facilitates the limiting of rotating rod 13, external thread 16 is threadedly connected with internal thread 24, which facilitates the rotation of rotating rod 13 to drive sliding sleeve 2 to move, the upper end of sliding sleeve 2 outer wall is fixedly connected with multiple limiting blocks 23, limiting block 23 is slidably connected with the outer wall of positioning rod 11, which facilitates the limiting of sliding sleeve 2 to move horizontally, the lower end of conveying pipe 1 is connected with multiple drip heads 3, which facilitates the drip irrigation of plants, movable plug 22 is wide at the top and narrow at the bottom, and the upper end outer wall is tightly attached to the inner wall of the lower end of conveying pipe 1, when movable plug 22 is lowered, due to its shape characteristics, the liquid passage can be quickly and effectively reduced, achieving fine control of flow, and vice versa, when it rises, the passage area can also be stably increased.

[0033] Working principle: when using, the conveying pipe 1 facilitates the conveying of liquid; when it is necessary to adjust the flow of drip irrigation, the operator rotates the knob 14, which drives the rotation of the rotating rod 13 fixedly connected with the knob 14; since the external thread 16 at the lower end of the outer wall of the rotating rod 13 is engaged with the internal thread 24 at the upper end of the inner wall of the sliding sleeve 2, the rotating movement of the rotating rod 13 is converted into the longitudinal movement of the sliding sleeve 2; at the same time, the limiting block 23 at the outer wall of the sliding sleeve 2 slides on the outer wall of the positioning rod 11, which ensures that the sliding sleeve 2 can only stably move in a straight line along the positioning rod 11 and cannot deviate; with the up-and-down movement of the sliding sleeve 2, the movable plug 22 connected with the sliding sleeve 2 through the connecting rod 21 also correspondingly adjusts the height in the conveying pipe 1; since the movable plug 22 is wide at the cross section and narrow at the top and tightly fits the inner wall of the lower end of the conveying pipe 1, when the movable plug 22 rises, the flow passage area of the liquid in the conveying pipe 1 increases, and the flow of the drip irrigation head 3 increases; conversely, when the movable plug 22 descends, the flow passage area of the liquid decreases, and the flow of the drip irrigation head 3 decreases.

[0034] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application is made with reference to the foregoing embodiments, for those skilled in the art, it can still be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
