Ensuring the supply and efficient use of agricultural irrigation water has become a key factor in ensuring food security and sustainable agricultural development.

[0003] At present, when irrigating high-standard farmland, water supply pipes are usually pre-buried deep in the ground of the farmland, and then sprinkler pipes are installed on the water supply pipes, and the farmland is irrigated through the nozzles on the sprinkler pipes.

[0039] In order to facilitate the irrigation of farmland, water is supplied to the interior of the water supply pipe 1 through an external high-pressure water pump. After the water flows into the interior of the water supply pipe 1, it will enter the interior of the connecting pipe 2. At this time, the water outlet 135 corresponds to the position of the water outlet pipe 11, and the water will enter the interior of the water outlet pipe 11 through the water outlet 135, so that the water will flow out through the water outlet pipe 11, thereby facilitating the irrigation of farmland.

[0040] See also Figure 1 , Figure 2 , Figure 7 and Figure 8 A top ring 21 is fixedly provided at the top of the connecting pipe 2, and a circular ring 22 used in conjunction with the top ring 21 is provided on the outside of the water spray pipe 3, and the bottom of the circular ring 22 contacts the upper part of the top ring 21. A plurality of limiting grooves 23 distributed in a circumferential array are provided on the upper end of the outer side of the water spray pipe 3, and a positioning mechanism 24 is fixedly provided inside the limiting groove 23. The positioning mechanism 24 includes a third spring 241 fixedly provided inside the limiting groove 23, and a connecting block 242 is fixedly provided at one end of the third spring 241 away from the inner wall of the limiting groove 23, and a positioning block 243 is fixedly provided on the side of the connecting block 242 away from the third spring 241, and the upper and lower sides of the positioning block 243 are both sloped, and a plurality of positioning ports 25 used in conjunction with the positioning block 243 are provided inside the top ring 21, and the side of the positioning block 243 away from the connecting block 242 passes through the limiting groove 23 and is plugged into the positioning port 25.

[0041] In order to ensure the stability of the water spray pipe 3 when irrigating farmland, after the water flows into the interior of the connecting pipe 2, the water will impact the turbine blade 4. At this time, the positioning block 243 is located in the positioning port 25. Then, after the water flows into the interior of the connecting pipe 2, the water spray pipe 3 will not rotate, thereby ensuring the stability of the water spray pipe 3 when irrigating farmland.

[0042] See also Figure 2 and Figure 3 A tooth plate 8 is fixedly provided at the bottom of the connecting ring 7, and the bottom end of the tooth plate 8 penetrates into the interior of the water supply pipe 1. An adjusting mechanism 9 used in conjunction with the tooth plate 8 is provided on the outside of the water supply pipe 1.

[0043] The adjusting mechanism 9 includes a shell 901 fixedly arranged on the outside of the water supply pipe 1, a rotating rod 902 is rotatably arranged inside the shell 901, one end of the rotating rod 902 penetrates into the inside of the water supply pipe 1 and is fixedly arranged with a gear 903, the gear 903 is meshed with the tooth plate 8, the adjusting mechanism 9 also includes a handle 904 rotatably arranged on the upper part of the shell 901, a worm 905 is rotatably arranged inside the shell 901, and the top end of the worm 905 is connected to the bottom end of the handle 904, a worm wheel 906 is fixedly arranged on the outside of the rotating rod 902, and the worm wheel 906 is meshed with the worm 905.

[0044] In order to facilitate the spraying and irrigation of crops in the farmland, first, the handle 904 is turned to drive the worm 905 to rotate. The rotation of the worm 905 drives the rotating rod 902 to rotate through the worm gear 906. The rotation of the rotating rod 902 drives the gear 903 to rotate. The rotation of the gear 903 can drive the tooth plate 8 to move upward. The upward movement of the tooth plate 8 will drive the connecting ring 7 to move upward. The upward movement of the connecting ring 7 will drive the water spray pipe 3 to move upward. The upward movement of the water spray pipe 3 can drive the nozzle 6 to move upward, thereby driving the nozzle 6 originally located in the connecting pipe 2 to move out of the connecting pipe 2, and the positioning block 243 will also be driven to move upward during the upward movement of the water spray pipe 3. Since the upper and lower sides of the positioning block 243 are sloped, the positioning block 243 can The arc block 132 is moved upward on the vertical rod 131 by the elastic force of the second spring 134, so that the upper part of the arc block 132 contacts the inner wall of the groove 12, and the upward movement of the arc block 132 drives the arc blocking plate 133 to move upward, so that the water outlet 135 is moved upward away from the water outlet pipe 11. At this time, the water outlet pipe 11 can be blocked by the arc blocking plate 133, and the water flow entering the connecting pipe 2 will enter the water spray pipe 3, making it convenient for the subsequent irrigation of crops in the farmland.

[0045] See also Figure 2 and Figure 8 A plurality of guide openings 27 distributed in a circular array are provided inside the connecting tube 2, and a plurality of guide blocks 28 distributed in a circular array are fixedly provided on the outside of the connecting ring 7. The side of the guide block 28 away from the connecting ring 7 passes through the guide opening 27 and is slidably connected to the guide opening 27.

[0046] In order to ensure the stability of the connecting ring 7 when it moves inside the connecting pipe 2, as mentioned above, when the tooth plate 8 moves up to drive the connecting ring 7 to move upward, the connecting ring 7 moves to drive the guide block 28 to slide in the guide port 27. The cooperation between the guide block 28 and the guide port 27 makes the connecting ring 7 more stable during the movement, and also makes the water spray pipe 3 more stable during the movement.

[0047] See also Figure 6 , Fig. 9 , Fig.10 and Fig.11 An annular water inlet 14 is provided at one end of the nozzle 6 close to the water spray pipe 3, and a plurality of water guide ports 15 connected to the annular water inlet 14 are provided inside the nozzle 6. A first spring 16 is provided inside the nozzle 6, and a blocking block 17 is fixedly provided at one end of the first spring 16 away from the inner wall of the nozzle 6, and the blocking block 17 is located at the water guide port 15, and a plurality of water spray ports 18 distributed in a circular array are provided on the blocking block 17, and a connecting rod 19 is fixedly provided at the center position of a side of the blocking block 17 away from the first spring 16, and the end of the connecting rod 19 away from the blocking block 17 abuts against the inner wall of the water spray pipe 3, and a limiting ring 20 is fixedly provided on the side of the nozzle 6 away from the first spring 16.

[0048] In order to improve the irrigation effect on crops when irrigating crops, as mentioned above, after the nozzle 6 is moved out from the inside of the water spray pipe 3, the connecting rod 19 is also moved out from the inside of the connecting pipe 2. At this time, the connecting rod 19 does not contact the inner wall of the connecting pipe 2, so that the extrusion force on the connecting rod 19 disappears, and the elastic force of the first spring 16 can push the blocking block 17 to move, so that the blocking block 17 abuts against the limit ring 20. At this time, the blocking block 17 is away from the water guide port 15. At this time, the water flow entering the inside of the connecting pipe 2 will impact the turbine blades 4 and enter the inside of the water spray pipe 3. After the water flow enters the inside of the water spray pipe 3, it will enter the annular water inlet 14, and then Then it enters the interior of the sprinkler head 6 through the water guide port 15, and is finally sprayed out through the water spray port 18 to irrigate the crops in the farmland by spraying. At the same time, the turbine blades 4 will drive the sprinkler pipe 3 to rotate, so that the sprinkler head 6 can rotate accordingly, so that the sprinkler head 6 can evenly spray the crops around it, thereby expanding the range of sprinkler irrigation. In addition, by setting three groups of sprinkler heads 6 at different heights, in the process of irrigating the crops, the appropriate number of sprinkler heads 6 can be moved out of the connecting pipe 2 according to the irrigation needs, and the spraying range of the crops can be flexibly adjusted, thereby ensuring sufficient irrigation of the crops and greatly improving the irrigation effect of the crops.

[0049] See also Figure 1 , Figure 2 , Figure 4 and Fig. 9 A medicine supply mechanism 10 for use with the nozzle 6 is provided on the upper part of the water spray pipe 3. The medicine supply mechanism 10 includes a connecting pipe 101 fixedly arranged on the upper part of the water spray pipe 3. The upper part of the connecting pipe 101 is rotatably connected to a medicine supply pipe 102. The outer side of the connecting pipe 101 is fixedly connected to a medicine guide pipe 103. The end of the medicine guide pipe 103 away from the connecting pipe 101 passes through the two annular openings 5 ​​at the upper end and is connected to the annular opening 5 at the lower end.

[0050] The medicine supply mechanism 10 also includes an annular tube 104 fixedly arranged in the annular opening 5, and the outer side of the annular tube 104 is fixedly connected to a plurality of medicine outlet tubes 105 distributed in a circular array, and one end of the medicine outlet tube 105 away from the annular tube 104 passes through the annular water inlet 14, and the outer side of the drug guiding tube 103 is fixedly connected to a plurality of medicine delivery tubes 106 distributed in a linear array, and one end of the medicine delivery tube 106 away from the medicine guiding tube 103 is connected to the annular tube 104, and a one-way valve 107 is fixedly arranged on the outer side of the medicine delivery tube 106.

[0051] In order to facilitate the spraying of nutrients on crops while irrigating them, as mentioned above, when irrigating crops, a mounting frame with a height higher than the connecting pipe can be erected on the outside of the connecting pipe, and then a drug supply pump is set on the mounting frame, and then the drug supply pipe 102 is connected to the drug supply pump, and then the drug supply pump is used to supply nutrient solution into the drug supply pipe 102, and the nutrient solution passes through the connecting pipe 101 and the drug guide pipe 103 in turn, and then the nutrient solution enters the annular pipe 104 through the drug delivery pipe 106, and then the nutrient solution inside the annular pipe 104 enters the inside of the annular water inlet 14 through the drug outlet pipe 105, and finally enters the inside of the nozzle 6 through the water guide port 15 and is sprayed out, so as to facilitate the spraying of nutrients while irrigating the crops and meet the growth needs of the crops.

[0052] See also Figure 6 , Fig.10 and Fig.11 A plurality of dredging rods 26 distributed in a circular array are fixedly arranged inside the nozzle 6, and the plurality of dredging rods 26 are all located on the outside of the first spring 16, and one end of the dredging rod 26 away from the inner wall of the nozzle 6 is inserted into the water outlet 18, and one end of the dredging rod 26 away from the inner wall of the nozzle 6 and one end of the connecting rod 19 away from the blocking block 17 are both conical.

[0053] In order to ensure the irrigation effect of crops in the farmland, after the irrigation of crops in the farmland is completed, the handle 904 is turned to drive the gear plate 8 to move downward using the gear 903, thereby driving the water spray pipe 3 to move to the initial position, so that the nozzle 6 located outside the connecting pipe 2 moves back to the inside of the connecting pipe 2. In the process of the nozzle 6 moving to the inside of the connecting pipe 2, the downward movement of the nozzle 6 will drive the connecting rod 19 to move downward, so that the connecting rod 19 abuts against the inner wall of the connecting pipe 2 again. At this time, the connecting rod 19 will drive the blocking block 17 to move to re-block the water guide port 15, and the dredging rod 26 will be inserted into the water spray port 18 during the movement of the blocking block 17. The dredging rod 26 can be used to dredge and clean the water spray port 18 on the blocking block 17, thereby ensuring the spray effect. The head 6 can discharge water normally to irrigate the crops in the farmland, and in the process of the water spray pipe 3 moving downward, it will also drive the positioning block 243 to move downward. When the top ring 21 contacts the circular ring 22, the water spray pipe 3 stops moving downward. At this time, the positioning block 243 may not be exactly aligned with the positioning port 25 after moving downward. Then, in the next process of irrigating the farmland, when the water flows into the interior of the connecting pipe 2, the water flows will impact the turbine blades 4 and drive the water spray pipe 3 to rotate. The rotation of the water spray pipe 3 drives the positioning block 243 to rotate. When the positioning block 243 rotates to the positioning port 25, the elastic force of the third spring 241 can be used to drive the positioning block 243 to be inserted into the positioning port 25, and the water spray pipe 3 can be limited and locked so that it no longer rotates, thereby reducing the wear of the connecting rod 19.

[0054] In the specific work, firstly, a water supply pipe 1 is pre-buried in each area of ​​the standardized farmland (see Fig.13 ), the pre-buried depth of the water supply pipe 1 can be about one meter underground in the farmland (the purpose is not to affect the planting of crops in the farmland), and multiple connecting pipes 2 can be installed on the water supply pipe 1 at intervals, and then the multiple water supply pipes 1 are connected to the external main water pipe through the branch pipe, and the main valve is installed on the main water pipe (in actual use, a valve can also be installed on each branch pipe). When it is necessary to irrigate the farmland, open the main valve on the main water pipe, and then supply water to the main water pipe through an external high-pressure water pump, and then the water flows into the interior of the water supply pipe 1 through the branch pipe. After the water flows into the interior of the water supply pipe 1, it will enter the interior of the connecting pipe 2. At this time, the water outlet 135 corresponds to the position of the outlet pipe 11, and the water will enter the interior of the outlet pipe 11 through the water outlet 135, so that the water will flow out through the outlet pipe 11, thereby facilitating the irrigation of the farmland. At this time, since the positioning block 243 is located in the positioning port 25, the water will not drive the water spray pipe 3 to rotate through the turbine blades 4 after entering the interior of the connecting pipe 2.

[0055] When it is necessary to irrigate the crops in the farmland, the handle 904 is turned to drive the worm 905 to rotate, and the rotation of the worm 905 drives the rotating rod 902 to rotate through the worm gear 906, and the rotation of the rotating rod 902 can drive the tooth plate 8 to move upward through the gear 903. The upward movement of the tooth plate 8 will drive the connecting ring 7 to move upward, and the upward movement of the connecting ring 7 will drive the water spray pipe 3 to move upward. The upward movement of the water spray pipe 3 can drive the nozzle 6 to move upward, thereby driving the nozzle 6 originally located inside the connecting pipe 2 to move out of the inside of the connecting pipe 2. At this time, the connecting rod 19 is also moved out of the inside of the connecting pipe 2, so that the connecting rod 19 does not contact the inner wall of the connecting pipe 2, and the extrusion force on the connecting rod 19 disappears, then the elastic force of the first spring 16 can push the blocking block 17 to move, so that the blocking block 17 is away from the water guide port 15, and water is sprayed. In the process of the pipe 3 moving upward, the positioning block 243 will also be driven to move upward. Since the upper and lower sides of the positioning block 243 are both sloped, the positioning block 243 can be moved out of the positioning port 25, thereby canceling the limit on the water spray pipe 3. At the same time, in the process of the connecting ring 7 moving upward, it will be away from the arc block 132, and the extrusion force on the arc block 132 will disappear. The elastic force of the second spring 134 can be used to drive the arc block 132 to slide upward on the vertical rod 131, so that the upper part of the arc block 132 contacts the inner wall of the groove 12. The upward movement of the arc block 132 drives the arc blocking plate 133 to move upward, so that the water outlet 135 is moved upward away from the water outlet pipe 11. At this time, the water outlet pipe 11 can be blocked by the arc blocking plate 133, and the water flow entering the connecting pipe 2 will enter the water spray pipe 3.

[0056] After the water flows into the interior of the water spray pipe 3, it will enter the annular water inlet 14, then enter the interior of the nozzle 6 through the water guide port 15, and finally be sprayed out through the water spray port 18 to irrigate the crops in the farmland. At the same time, the water spray pipe 3 will be driven to rotate by the turbine blades 4, so that the nozzle 6 can rotate accordingly, so that the nozzle 6 can evenly spray the crops around it, thereby expanding the range of water spraying and irrigation. In addition, by setting up three groups of nozzles 6 at different heights, during the process of irrigating the crops, the appropriate number of nozzles 6 can be moved out of the water spray pipe 3 according to the irrigation needs, so that the spraying range of the crops can be flexibly adjusted, thereby ensuring that the crops are fully irrigated and greatly improving the irrigation effect of the crops.

[0057] When irrigating crops, the medicine supply pipe 102 is connected to an external medicine supply pump, and then the medicine supply pump is used to supply nutrient solution into the medicine supply pipe 102. The nutrient solution passes through the connecting pipe 101 and the medicine guide pipe 103 in turn, and then the nutrient solution enters the annular pipe 104 through the medicine delivery pipe 106. Then the nutrient solution inside the annular pipe 104 enters the inside of the annular water inlet 14 through the medicine outlet pipe 105, and finally enters the inside of the nozzle 6 through the water guide port 15 and is sprayed out, so as to facilitate the spraying of nutrients while irrigating the crops, thereby meeting the growth needs of the crops.
