Description

Technical Field

[0001] This invention relates to the field of farmland irrigation technology, specifically to a water-saving adaptive irrigation device for farmland. Background Technology

[0002] In the field of agricultural production, irrigation is a core link in ensuring crop growth and increasing yield. Its technical rationality and resource utilization efficiency are directly related to the economic and ecological benefits of agricultural production. At present, my country's farmland irrigation still faces two major contradictions: on the one hand, the imbalance between water supply and demand is prominent, and traditional irrigation methods result in serious water waste; on the other hand, existing irrigation devices are difficult to adapt to the diverse needs of farmland crops, and the precision and coverage of irrigation are insufficient, resulting in a mismatch between irrigation effects and resource input.

[0003] When traditional devices are in use, the spray angle, height, and distance of the irrigation device are all fixed because the nozzle angle is fixed. This can easily lead to irrigation blind spots or insufficient irrigation in farmland, requiring manual secondary irrigation to make up for the deficiencies. This consumes a lot of human resources and causes repeated waste of water resources. Summary of the Invention

[0004] This invention adjusts the spraying height and distance by reciprocating the rotation of multiple sets of nozzles B, irrigating crops in different areas, reducing irrigation blind spots, preventing secondary irrigation operations due to local lack of irrigation, reducing human resource input for secondary irrigation and lowering labor costs, and preventing water resource consumption caused by repeated irrigation, thereby improving water resource utilization.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a water-saving adaptive irrigation device for farmland, comprising a base plate, a plurality of rods installed at the lower end of the base plate, a sealing groove provided at the lower end of the base plate, a water supply device connected to one end of the sealing groove, a rotating shaft rotating inside the sealing groove, a water storage pipe connected to the other end of the sealing groove, a rotating shaft driven by the rotating shaft rotating inside the water storage pipe, a plurality of nozzles A connected to the outside of the water storage pipe, a sealing ring rotating inside the water storage pipe, and the plurality of nozzles A intermittently spraying water through the rotation of the sealing ring, a plurality of nozzles B rotating outside the water storage pipe, and the plurality of nozzles B all communicating with the inside of the water storage pipe, a reciprocating screw connected to one end of the water storage pipe, a sliding seat sliding outside the reciprocating screw, and the plurality of nozzles B flipping by sliding the sliding seat.

[0006] Preferably, one end of the sealing groove is connected to a connecting pipe A, and the other end of the connecting pipe A is connected to a water supply device.

[0007] Preferably, multiple sets of blades are fixedly connected to the outside of the rotating shaft, the rotating shaft is rotatably connected to the inside of the sealing groove, and the rotating shaft is located at the center of the lower end of the base plate.

[0008] Preferably, the water storage pipe is embedded inside the base plate, and the other end of the rotating shaft is connected to a connecting pipe B, the other end of the connecting pipe B is connected to the water storage pipe, and the water storage pipe is located at the center of the base plate.

[0009] Preferably, one end of the rotating shaft is connected to a rotating shaft, and the other end of the rotating shaft extends through the connecting pipe B and the water storage pipe to the upper end of the water storage pipe.

[0010] Preferably, a bracket is installed at the upper end of the water storage pipe, and multiple sets of movable buckles are installed on the outside of the bracket. Each set of movable buckles is rotatably connected to a nozzle B. One end of the nozzle B is connected to a flexible hose, and the other end of the flexible hose is connected to the inside of the water storage pipe.

[0011] Preferably, the slide is connected to a reciprocating lead screw ball nut assembly, and a disc is rotatably connected to one end of the reciprocating lead screw. A limit rod is fixedly connected to one end of the disc, and the other end of the limit rod extends through the slide into the interior of the slide.

[0012] Preferably, multiple sets of connecting rods are fixedly connected to the outside of the slide block, and the other end of each set of connecting rods is connected to the nozzle B.

[0013] Preferably, the sealing ring is fixedly connected to the outside of the rotating shaft, and the outer diameter of the sealing ring matches the inner diameter of the water storage pipe.

[0014] Preferably, the outer side of the sealing ring has multiple sets of through holes, and the multiple sets of through holes and the multiple sets of nozzles A are all located on the same plane.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By adjusting the spraying height and distance through the reciprocating rotation of multiple sets of nozzles B, irrigation of crops in different areas can be achieved, reducing irrigation blind spots and preventing secondary irrigation operations due to local lack of irrigation. At the same time, it reduces the human resource input for secondary irrigation, lowers labor costs, and prevents water consumption caused by repeated irrigation, thereby improving water resource utilization.

The instantaneous pressure reduction in the water storage pipe caused by nozzle A ensures balanced irrigation of crops in both near and far areas, preventing localized under- or over-irrigation. At the same time, the intermittent water output of nozzle A, which rotates with the sealing ring, prevents the surrounding soil from becoming saturated or unable to absorb water in time due to continuous irrigation, reducing deep water seepage or surface runoff loss, and further improving the effective utilization rate of water resources.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 6 This invention provides a water-saving adaptive irrigation device for farmland, including a base plate 1. Multiple sets of insert rods 2 are installed at the lower end of the base plate 1. A sealing groove 3 is provided at the lower end of the base plate 1. One end of the sealing groove 3 is connected to a water supply device. A rotating shaft 4 rotates inside the sealing groove 3. The other end of the sealing groove 3 is connected to a water storage pipe 8. A rotating shaft 9 driven by the rotating shaft 4 rotates inside the water storage pipe 8. Multiple sets of nozzles A10 are connected to the outside of the water storage pipe 8. A sealing ring 11 rotates inside the water storage pipe 8, and the multiple sets of nozzles A10 spray water intermittently through the rotation of the sealing ring 11. Multiple sets of nozzles B15 rotate on the outside of the water storage pipe 8, and the multiple sets of nozzles B15 are all connected to the inside of the water storage pipe 8. A reciprocating screw 12 is connected to one end of the water storage pipe 8. A sliding seat 17 slides on the outside of the reciprocating screw 12, and the multiple sets of nozzles B15 are flipped by sliding the sliding seat 17.

[0021] In an optional embodiment, one end of the sealing groove 3 is connected to a connecting pipe A6, and the other end of the connecting pipe A6 is connected to a water supply device. When using the device, the staff fixes the base plate 1 to the ground using multiple sets of rods 2. After fixing the base plate 1, the water supply equipment is started. After the water supply equipment is started, it will deliver water to the inside of the sealed groove 3 through the connecting pipe A6. The water supply equipment will automatically open or close according to the soil moisture, and then automatically irrigate when the soil moisture is low.

[0022] In an optional embodiment, multiple sets of blades 5 are fixedly connected to the outside of the rotating shaft 4, the rotating shaft 4 is rotatably connected to the inside of the sealing groove 3, and the rotating shaft 4 is located at the center of the lower end of the base plate 1. After the water source enters the sealing groove 3, the sealing groove 3 will transport the water source to the connecting pipe B7. When the water source passes through the sealing groove 3, the water source will drive two sets of multiple blades 5 to rotate. When the multiple blades 5 rotate, the multiple blades 5 will synchronously drive the rotating shaft 4 to rotate.

[0023] In an optional embodiment, the water storage pipe 8 is embedded inside the base plate 1, and the other end of the rotating shaft 4 is connected to the connecting pipe B7. The other end of the connecting pipe B7 is connected to the water storage pipe 8, and the water storage pipe 8 is located at the center of the base plate 1. After the water source enters the connecting pipe B7, the connecting pipe B7 will transport the water source to the water storage pipe 8. After the water source enters the water storage pipe 8, as the water source gradually accumulates, the water level inside the water storage pipe 8 will gradually rise.

[0024] In an optional embodiment, one end of the rotating shaft 4 is connected to the rotating shaft 9, and the other end of the rotating shaft 9 extends through the connecting pipe B7 and the water storage pipe 8 to the upper end of the water storage pipe 8. When rotating shaft 4 rotates, it will synchronously drive rotating shaft 9 to rotate.

[0025] In an optional embodiment, a bracket 13 is installed on the upper end of the water storage pipe 8, and multiple sets of movable buckles 14 are installed on the outside of the bracket 13. Each set of movable buckles 14 is rotatably connected to a nozzle B15. One end of the nozzle B15 is connected to a hose 16, and the other end of the hose 16 is connected to the inside of the water storage pipe 8. As the water level inside the water storage pipe 8 gradually rises to the top of the water storage pipe 8, the water pressure inside the water storage pipe 8 will increase as water continues to enter the water storage pipe 8. As the water pressure inside the water storage pipe 8 increases, the water pressure will push the water into the multiple sets of hoses 16. After the water enters the multiple sets of hoses 16, the water will be sprayed outward through the multiple sets of nozzles B15.

[0026] In an optional embodiment, the slide 17 is connected to the ball nut pair of the reciprocating screw 12, and a disc is rotatably connected to one end of the reciprocating screw 12. A limit rod 19 is fixedly connected to one end of the disc, and the other end of the limit rod 19 extends through the slide 17 into the interior of the slide 17. When the rotating shaft 9 rotates, it will synchronously drive the reciprocating screw 12 to rotate. When the reciprocating screw 12 rotates, it will not drive the disk to rotate. When the reciprocating screw 12 rotates, it will drive the slide 17 to reciprocate along the outside of the connecting rod 18.

[0027] In an optional embodiment, a plurality of connecting rods 18 are fixedly connected to the outside of the slide 17, and the other end of each of the plurality of connecting rods 18 is connected to the nozzle B15. As the slide 17 reciprocates, it simultaneously drives multiple sets of connecting rods 18 to reciprocate. This reciprocating motion of the connecting rods 18, in turn, drives multiple sets of nozzles B15 to rotate back and forth. As the nozzles B15 rotate, the height of their output ends is continuously adjusted. Consequently, when the nozzles B15 spray water, the spray height and distance are synchronously changed by the position of their output ends. This allows for rapid irrigation of crops at different distances, preventing blind spots and the waste of manpower and water resources caused by secondary irrigation. By adjusting the spray height and distance through the reciprocating rotation of the nozzles B15, irrigation of crops in different areas is achieved, reducing blind spots and preventing secondary irrigation due to localized neglect. This reduces manpower input for secondary irrigation, lowering labor costs, and prevents water consumption from repeated irrigation, thus improving water resource utilization.

[0028] In an optional embodiment, the sealing ring 11 is fixedly connected to the outside of the rotating shaft 9, and the outer diameter of the sealing ring 11 matches the inner diameter of the water storage pipe 8; When the rotating shaft 9 rotates, it will simultaneously drive the sealing ring 11 to rotate inside the water storage pipe 8.

[0029] In an optional embodiment, multiple sets of through holes are provided on the outer side of the sealing ring 11, and the multiple sets of through holes and multiple sets of nozzles A10 are all located on the same plane. When the sealing ring 11 rotates, and the multiple sets of through holes on the outer side of the sealing ring 11 rotate to be flush with the nozzles A10, water will be sprayed outward through the multiple sets of nozzles A10 due to pressure. This spraying of water will irrigate crops nearby. Simultaneously, the water pressure inside the water storage pipe 8 will momentarily decrease as water is sprayed outward through the multiple sets of nozzles A10, thus irrigating crops further away while also better addressing the irrigation of nearby crops. Furthermore, because the multiple sets of nozzles A10 open intermittently with the rotation of the sealing ring 11, continuous pressure on the surrounding area is prevented. Irrigation of the surrounding soil prevents the soil from absorbing water quickly, leading to water loss. By intermittently opening the nozzle A10, irrigation is provided to crops nearby. The instantaneous pressure drop in the water storage pipe 8 caused by the nozzle A10 spraying water ensures balanced irrigation for crops in both near and far areas, preventing localized under- or over-irrigation. At the same time, the intermittent water discharge from the nozzle A10, which rotates with the sealing ring 11, prevents the surrounding soil from becoming saturated or unable to absorb water in time due to continuous irrigation. This reduces deep water seepage or surface runoff loss, further improving the effective utilization rate of water resources.

[0030] Working principle: When using the device, the operator fixes the base plate 1 to the ground using multiple sets of insert rods 2. After fixing the base plate 1, the water supply equipment is started. After the water supply equipment is started, it will deliver water to the sealed groove 3 through the connecting pipe A6. The water supply equipment will automatically open or close according to the soil moisture, and then automatically irrigate when the soil moisture is low. After the water enters the sealed groove 3, the sealed groove 3 will deliver the water to the connecting pipe B7. When the water passes through the sealed groove 3, the water will drive two sets of multiple blades 5 to rotate. When the multiple blades 5 rotate, they will synchronously drive the rotating shaft 4 to rotate. When the rotating shaft 4 rotates, it will synchronously drive the rotating shaft 9 to rotate. After the water source enters the connecting pipe B7, the connecting pipe B7 will transport the water source to the water storage pipe 8. After the water source enters the water storage pipe 8, as the water source gradually accumulates, the water level inside the water storage pipe 8 will gradually rise. When the water level inside the water storage pipe 8 gradually rises to the top of the water storage pipe 8, the water pressure inside the water storage pipe 8 will increase as the water source continues to enter the water storage pipe 8. As the water pressure inside the water storage pipe 8 increases, the water pressure will push the water source into the multiple sets of hoses 16. After the water source enters the multiple sets of hoses 16, the water source will be sprayed outward through the multiple sets of nozzles B15. When the rotating shaft 9 rotates, it will synchronously drive the reciprocating screw 12 to rotate. When the reciprocating screw 12 rotates, it will not drive the disk to rotate. When the reciprocating screw 12 rotates, it will drive the slide 17 to move back and forth along the outside of the connecting rod 18. When the slide 17 moves back and forth, it will synchronously drive multiple sets of connecting rods 18 to move back and forth. When the multiple sets of connecting rods 18 move back and forth, they will synchronously drive multiple sets of nozzles B15 to rotate back and forth. When the multiple sets of nozzles B15 rotate back and forth, they will continuously adjust the height of the output end of the multiple sets of nozzles B15. Thus, when the multiple sets of nozzles B15 spray water, the spray height and distance of the water source will be synchronously changed by the change of the position of the output end. When the rotating shaft 9 rotates, it will synchronously drive the sealing ring 11 to rotate inside the water storage pipe 8. When the sealing ring 11 rotates, when the multiple sets of through holes on the outside of the sealing ring 11 rotate to be flush with the nozzle A10, the water source will be sprayed outward through the multiple sets of nozzles A10 due to pressure. As the water source is sprayed outward through the multiple sets of nozzles A10, it will irrigate the crops nearby. At the same time, when the water source is sprayed outward through the multiple sets of nozzles A10, the water pressure inside the water storage pipe 8 will drop instantaneously, thus irrigating the crops nearby while irrigating the crops far away.
