Description

Technical Field

[0001] This invention relates to the field of agricultural planting equipment technology, specifically to a drip irrigation and fertilization integrated precision irrigation and fertilization device. Background Technology

[0002] In the long-term development of agricultural production, irrigation and fertilization are key links to ensure crop growth. The scientific nature of their technical methods directly affects agricultural production efficiency, resource utilization, and the ecological environment. With the advancement of agricultural modernization, people's demand for water-saving, fertilizer-saving, efficient, and environmentally friendly agricultural technologies is becoming increasingly urgent, leading to the emergence of irrigation and fertilization devices that dissolve fertilizer and mix it with water to achieve integrated water and fertilizer management.

[0003] In the planting areas of Xinjiang, the rubber irrigation pipes are easily damaged by animals, and some planting areas in Xinjiang also have significant sandstorms. These sandstorms can easily cover the irrigation nozzles, causing the irrigation liquid to condense the sand near the nozzles, thus affecting water and fertilizer application. Therefore, it is necessary to propose a drip irrigation and fertilization integrated precision irrigation and fertilization device. Summary of the Invention

[0004] To address the problems in the existing technology, the present invention provides a drip irrigation and fertilization integrated precision irrigation and fertilization device.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a drip irrigation and fertilization integrated precision irrigation and fertilization device, including a protective pipe, a rotating rod rotatably connected inside the protective pipe, and a drive component being provided on both the protective pipe and the rotating rod;

[0006] The rotating rod has a storage groove, the inner wall of the protective pipe has a placement groove, the upper end of the placement groove has a sliding hole, the outer wall of the protective pipe has a retaining groove, a connecting pipe is slidably connected in the sliding hole, the upper end of the connecting pipe extends into the retaining groove and is fixedly connected to a nozzle, the lower end of the connecting pipe extends into the storage groove and is fixedly installed with a solenoid valve, the rotating rod has an air inlet, a first connecting hole is formed between the air inlet and the storage groove, the rotating rod has a water inlet, the wall of the water inlet has a storage groove, a second connecting hole is formed between the air inlet and the storage groove, an airbag is fixedly installed at the opening of the second connecting hole in the storage groove, and a push plate is fixedly installed on the airbag.

[0007] Specifically, a sealing plate is rotatably connected inside the air intake, the sealing plate is arc-shaped, and the upper surface of the sealing plate is concave.

[0008] Specifically, the drive assembly includes a drive motor, which is fixedly installed on the outer wall of the protective pipe. A gear is fixedly installed at the output end of the drive motor via a coupling. A gear ring is fixedly installed at one end of the rotating rod, and the gear meshes with the gear ring.

[0009] Specifically, a baffle plate is fixedly installed at the opening of the storage tank.

[0010] Specifically, the nozzle is provided with a plurality of spray holes, and all of the spray holes are arranged at an angle.

[0011] Specifically, the push plate is slidably connected inside the storage tank, and the outer wall of the push plate abuts against the tank wall.

[0012] Specifically, the airbag is fixedly installed in the storage tank, and the air inlet of the airbag is connected to the second connecting hole, and the other end of the airbag is fixedly connected to the push plate.

[0013] The beneficial effects of this invention are as follows: The drip irrigation and fertilization integrated precision irrigation and fertilization device of this invention, during use, injects compressed air into the storage tank through the air inlet, using the air pressure to push out the nozzle. The nozzle rotates automatically with the help of airflow, clearing away surrounding sand and debris, thus clearing the path for operation. Rotating the rotating rod adjusts the connection between the storage tank and the placement tank; after injecting clean water, uniform irrigation is achieved through the nozzle.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1-6 As shown, the present invention provides the following technical solution:

[0024] Example 1: A drip irrigation and fertigation precision irrigation and fertilization device includes a protective pipe 1, a rotating rod 2 rotatably connected inside the protective pipe 1, and a drive assembly is provided on both the protective pipe 1 and the rotating rod 2.

[0025] A storage groove 3 is provided on the rotating rod 2, a placement groove 4 is provided on the inner wall of the protective pipe 1, a sliding hole 5 is provided through the upper end of the placement groove 4, a slot 6 is provided on the outer wall of the protective pipe 1, a connecting pipe 7 is slidably connected in the sliding hole 5, the upper end of the connecting pipe 7 extends into the slot 6 and is fixedly connected to the nozzle 8, the lower end of the connecting pipe 7 extends into the storage groove 3 and is fixedly installed with the solenoid valve 9, an air inlet 10 is provided through the rotating rod 2, a first connecting hole 11 is provided through the air inlet 10 and the storage groove 3, a water inlet 12 is provided through the rotating rod 2, a storage groove 13 is provided on the wall of the water inlet 12, a second connecting hole 21 is provided through the air inlet 10 and the storage groove 13, an airbag 14 is fixedly installed at the opening of the second connecting hole 21 located in the storage groove 13, and a push plate 15 is fixedly installed on the airbag 14;

[0026] A sealing plate 16 is rolled inside the air inlet 10. The sealing plate 16 is arc-shaped and its upper surface is concave.

[0027] The drive assembly includes a drive motor 17, which is fixedly installed on the outer wall of the protective pipe 1. A gear 18 is fixedly installed at the output end of the drive motor 17 via a coupling. A gear ring 19 is fixedly installed at one end of the rotating rod 2, and the gear 18 meshes with the gear ring 19.

[0028] When using it, the following steps are included:

[0029] 1) First, lay the protective pipe 1, then connect the water supply pipe to the water inlet 12, and connect the output end of the air compressor to the air inlet 10;

[0030] 2) Under its own center of gravity adjustment, the sealing plate 16 will remain below the air inlet 10 and seal the second connecting hole 21. The air compressor is started to inject air into the air inlet 10, and the air in the air inlet 10 is injected into the collection tank 3 through the first connecting hole 11. The gas entering the collection tank 3 will push the solenoid valve 9, the connecting pipe 7 and the nozzle 8 to rise, so that the solenoid valve 9 is disengaged from the collection tank 3 and enters the placement tank 4. At the same time, the nozzle 8 rises to the outside of the protective pipe 1. Then the solenoid valve 9 can be opened, and the air in the collection tank 3 enters the nozzle 8 through the solenoid valve 9 and the connecting pipe 7. The nozzle 8 sprays gas outward. Because the air jet hole on the nozzle 8 is set at an angle, the nozzle 8 will rotate itself when it sprays gas, so that the nozzle 8 can treat the sand and dust accumulated outside.

[0031] 3) At this time, start the drive motor 17 and stop the air compressor. The drive motor 17 drives the gear 18 to rotate. The gear 18 drives the rotating rod 2 to rotate through meshing with the gear ring 19. The rotating rod 2 rotates inside the protective pipe 1 and drives the rotating rod 2 to rotate 180°, so that the slot of the storage tank 13 is aligned with the slot of the placement tank 4. The baffle plate 20 supports the solenoid valve 9, the connecting pipe 7 and the nozzle 8, so that the solenoid valve 9, the connecting pipe 7 and the nozzle 8 remain in their original positions.

[0032] 4) When irrigating or fertilizing in large quantities, clean water or fertilizer can be injected into the water inlet 12. The clean water or fertilizer is injected into the storage tank 13 through the water inlet 12. Then, driven by the subsequent clean water or fertilizer, it enters the nozzle 8 through the solenoid valve 9 and the connecting pipe 7. At this time, the nozzle 8 sprays clean water or fertilizer outward and drives itself to rotate, so that the nozzle 8 irrigates or fertilizes the outside.

[0033] 5) During quantitative irrigation or fertilization, a mixture of clean water or fertilizer solution can be injected into the water inlet 12. The clean water or fertilizer solution fills the storage tank 13 through the water inlet 12, ensuring that the storage tank 13 is filled with a measured amount of clean water or fertilizer solution. Then, the air compressor is started to inject gas into the air inlet 10. Simultaneously, the sealing plate 16, due to its own center of gravity adjustment, will rotate to the bottom of the air inlet 10 and seal the first connecting hole 11, allowing the air in the air inlet 10 to be injected into the air bag through the second connecting hole 21. Inside 14, the airbag 14 inflates and pushes the push plate 15 upward. The push plate 15 squeezes the clean water or fertilizer water and enters the nozzle 8 through the solenoid valve 9 and the connecting pipe 7. At this time, the nozzle 8 sprays clean water or fertilizer water outward and pushes itself to rotate, so that the nozzle 8 irrigates or fertilizes the outside. Afterward, the air can be extracted by the air compressor, so that the airbag 14 returns to its original position. Then the above operation is repeated, so that targeted irrigation or fertilization can be achieved by spraying clean water or fertilizer water in multiple quantitative amounts.

[0034] 6) After irrigation or fertilization is completed, start the drive motor 17. The drive motor 17 drives the gear 18 to rotate. The gear 18 drives the rotating rod 2 to rotate through meshing with the gear ring 19. The rotating rod 2 rotates inside the protective pipe 1 and rotates 180°, so that the opening of the collection slot 3 is aligned with the opening of the placement slot 4. At this time, the solenoid valve 9 and the connecting pipe 7 are released from the support of the nozzle 8, so that the solenoid valve 9 descends into the collection slot 3 and the nozzle 8 descends into the slot 6, thereby preventing the nozzle 8 from being stored and preventing wind and sand from entering and animals from damaging it.

[0035] Example 2: The technical solutions in this example that differ from Example 1 include:

[0036] A baffle plate 20 is fixedly installed at the opening of the storage tank 13 to block the solenoid valve 9 and prevent it from falling into the storage tank 13. The nozzle 8 is provided with several spray holes, all of which are inclined. When air and water fertilizer are sprayed, the nozzle 8 will rotate, making the sand and dust removal more thorough and the water and fertilizer spraying more even. The push plate 15 is slidably connected in the storage tank 13, and the outer wall of the push plate 15 abuts against the tank wall of the storage tank 13. The air bag 14 is fixedly installed in the storage tank 13, and the air inlet of the air bag 14 is connected to the second connecting hole 21. The other end of the air bag 14 is fixedly connected to the push plate 15, so that the air bag 14 expands in the storage tank 13 and pushes the push plate 15 to move up and down parallel in the storage tank 13.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
