The existing irrigation method still uses continuous flooding irrigation throughout the year, which not only consumes a lot of water resources, but also takes a lot of labor and time. Therefore, it is particularly important for sustainable agricultural development to develop and implement intelligent control devices for alternating dry and wet irrigation of farmland to improve the utilization efficiency of irrigation water in a simple way.

[0003] Controlled wet-dry alternating irrigation is a new irrigation method that artificially keeps half of the crop root system wet and the other half in a dry soil environment, making full use of water and avoiding drought. Alternating irrigation is artificially controlled so that dry and wet areas appear alternately, that is, the area that was irrigated last time will be left dry the next time, while the area that was kept dry last time will be irrigated the next time, so that the roots in different areas can alternate and accept a certain degree of water stress.

[0021] S1: During installation, the device is plugged into one side of the crop through a plug-in rod;

[0022] S2: When irrigation is required on one side of the crop, the staff controls the water main pipe to rotate, and the water main pipe drives the screw tube to rotate. When the screw tube rotates, the outer sleeve moves along its axial direction, and the sleeve moves on the screw tube from the end away from the displacement assembly to the end close to the displacement assembly, so that the swing seat changes from being parallel to the water main pipe to being inclined to the water main pipe;

[0023] S3: When the main water pipe rotates, the driving gear meshes with the first large gear for transmission, and the first large gear drives the second large gear to rotate through the rotating shaft. At this time, the second large gear does not mesh with the driven gear, the drum does not reel in the pull rope, and the water spraying part on the slide performs irrigation on one side of the crop;

[0024] S4: After the irrigation is completed, the driving motor drives the water main pipe to continue rotating, and the sleeve moves along the guide screw tube track groove from the end close to the displacement assembly to the end far away from the displacement assembly. During this period, the second large gear is meshed with the driven gear, and the reel pulls the stretching part through the pull rope, so that the first elastic telescopic rod is stretched, and the slide seat slides on the swing seat, changing the overall position of the water spraying part placed on the swing seat;

[0025] S5: During the next irrigation, step S2 is repeated to realize the inclined arrangement of the swing seat and the water main pipe. During this period, the second large gear continues to mesh with the driven gear, and the drum continues to apply tension to the stretching part through the pull rope. The second elastic telescopic rod is stretched, and the slide seat remains at the current position of the swing seat. The water spraying part on the slide seat only irrigates the other side of the crop, realizing the alternating dry and wet irrigation on both sides of the crop.

[0026] S6: After the irrigation is completed, the driving motor drives the water main pipe to rotate, so that the swing seat is changed from being arranged obliquely with the water main pipe to being arranged parallel to the water main pipe;

[0027] S7: When continuing the next irrigation, repeat step S2 to realize the inclined arrangement of the swing seat and the water main pipe. During this period, the second large gear is no longer engaged with the driven gear, the first elastic telescopic rod and the second elastic telescopic rod are restored, and the slide moves back to the initial position of the swing seat, so that the water spray part irrigates the side of the crop initially irrigated again, realizing the reciprocating dry-wet alternating irrigation on both sides of the crop.

[0028] Compared with the prior art, the present invention provides an intelligent dry-wet alternating agricultural irrigation device and an irrigation method thereof, which have the following beneficial effects:

[0029] 1. The intelligent dry-wet alternating agricultural irrigation device and irrigation method thereof, through the coordinated action of the lateral movement mechanism and the displacement component, control the water spraying part on the water distribution pipe to perform dry-wet alternating irrigation on both sides of the crops at different distances in turn. There is no need to set up two pipelines for dry and wet irrigation on both sides of the crops respectively. The installation cost is low, and it can be stored and placed when not in use for irrigation, which is convenient for farmers to observe the growth of the operation.

[0030] 2. The intelligent dry-wet alternating agricultural irrigation device and irrigation method thereof, by arranging a plurality of water spraying parts on the slide, facilitates irrigation operations on the left or right sides of multiple rows of crops at the same time, and the spacing between the plurality of water spraying parts on the slide can be adjusted by rotating the screw to adapt to the planting spacing of the crops, is easy to use, and has a wide range of applications.

[0031] 3. The intelligent dry-wet alternating agricultural irrigation device and irrigation method thereof apply thrust to the paddle through the water flow in the fixed pipe during irrigation, so that the paddle drives the rotating shaft to rotate, and the rotating shaft drives the first connecting plate and the second connecting plate to move, and then the second connecting plate drives the sprinkler to swing left and right, thereby expanding the irrigation distance of the sprinkler to the crops in the horizontal direction, thereby reducing the number of sprinklers installed and avoiding the occurrence of irrigation dead corners, and ensuring the dry-wet alternating irrigation effect of crops.

A rotating joint 15 is provided at one end of the water supply main pipe 3, and a driving motor 16 is provided on the water supply main pipe 3.

[0052] Specifically, during installation, the device is plugged into one side of the crop through the plug rod 1, and the driving motor 16 is controlled to run.

The rotation of the water main pipe 3 will not affect the water pipe and the water distribution pipe 4 connected thereto under the action of the rotating joint 15 and the connecting ring 14. The water main pipe 3 drives the transverse movement mechanism to work, and the transverse movement mechanism drives the displacement component to move when working. Through the coordinated action of the transverse movement mechanism and the displacement component, the water spraying part 5 on the water distribution pipe 4 is controlled to perform dry and wet alternating irrigation on both sides of the crops at different distances each time. There is no need to set up two pipelines for dry and wet irrigation on both sides of the crops respectively.

[0069] S5: During the next irrigation, step S2 is repeated to realize the tilted arrangement of the swing seat 701 and the water main pipe 3.

10. An irrigation method according to claim 9, characterized in that: The following steps are involved: S1: During installation, the device is plugged into one side of the crop through the plugging rod (1); S2: When irrigation is required on one side of the crop, the staff controls the water main pipe (3) to rotate, and the water main pipe (3) drives the screw tube (6) to rotate. When the screw tube (6) rotates, the sleeve (601) on the outside moves along its axial direction, and the sleeve (601) moves on the screw tube (6) from the end away from the displacement assembly to the end close to the displacement assembly, so that the swing seat (701) changes from being parallel to the water main pipe (3) to being inclined with the water main pipe (3); S3: When the water main pipeline (3) rotates, the driving gear (301) meshes with the first large gear (902) for transmission, and the first large gear (902) drives the second large gear (903) to rotate through the rotating shaft (901). At this time, the second large gear (903) does not mesh with the driven gear (1001), the reel (1002) does not reel the pull rope (1003), and the water spraying part (5) on the slide seat (8) performs irrigation operation on one side of the crops; S4: After the irrigation is completed, the driving motor (16) drives the water main pipe (3) to continue rotating, and the sleeve (601) moves along the track groove of the screw tube (6) from the end close to the displacement assembly to the end away from the displacement assembly. During this period, the second large gear (903) is meshed with the driven gear (1001), and the reel (1002) pulls the stretching part (11) through the pull rope (1003), so that the first elastic telescopic rod (112) is stretched, and the sliding seat (8) slides on the swing seat (701), changing the overall position of the water spraying part (5) placed on the swing seat (701); S5: During the next irrigation, step S2 is repeated to realize the tilted arrangement of the swing seat (701) and the water main pipe (3). During this period, the second large gear (903) continues to mesh with the driven gear (1001), and the reel (1002) continues to apply tension to the stretching portion (11) through the pull rope (1003). The second elastic telescopic rod (113) is stretched, and the slide seat (8) remains at the current position of the swing seat (701). The water spraying portion (5) on the slide seat (8) only performs irrigation on the other side of the crop, thereby realizing dry-wet alternating irrigation on both sides of the crop. S6: After the irrigation is completed, the driving motor (16) drives the water main pipe (3) to rotate, so that the swing seat (701) changes from being arranged obliquely with the water main pipe (3) to being arranged parallel with the water main pipe (3); S7: When the next irrigation is continued, step S2 is repeated to realize the tilted arrangement of the swing seat (701) and the water main pipe (3). During this period, the second large gear (903) is no longer meshed with the driven gear (1001), the first elastic telescopic rod (112) and the second elastic telescopic rod (113) are restored, and the slide seat (8) moves back to the initial position of the swing seat (701), so that the water spraying part (5) irrigates the side of the crop initially irrigated again, thereby realizing the reciprocating dry-wet alternating irrigation of the two sides of the crop.
