Description

Technical Field

[0001] This invention relates to the field of sandy potato cultivation technology, specifically to a drip irrigation device for sandy potato cultivation. Background Technology

[0002] Drip irrigation is a method of watering crops by delivering water and nutrients drop by drop, evenly and slowly, into the root zone of the crop, according to the crop's water requirements. Drip irrigation does not damage the soil structure, maintaining optimal conditions for crop growth in terms of water, fertilizer, air, and heat. It minimizes evaporation loss, does not produce surface runoff, and has virtually no deep seepage, making it a water-saving irrigation method. The main characteristics of drip irrigation are: small water volume (the emitter's flow rate is approximately 1-2 liters per hour), allowing for longer irrigation durations and shorter irrigation cycles, enabling frequent, small-volume irrigation; low operating pressure, precise control of water volume, reduced ineffective inter-row evaporation, and no water waste.

[0003] In sandy soil potato cultivation, drip irrigation technology is often used to irrigate potatoes. When cultivating potatoes, nutrient agents need to be added to the water. Under the long-term operation of the pipeline, scale can easily accumulate inside the pipeline, causing blockage of the plastic pipeline and affecting the drip irrigation efficiency. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a drip irrigation device for potato cultivation in sandy areas, comprising a liquid storage tank for storing drip irrigation liquid, a liquid guide pipe fixedly installed on the top of the liquid storage tank, a feeding port fixedly installed on one side of the outer surface of the liquid storage tank, and a support frame fixedly installed on the bottom of the liquid storage tank;

[0005] A mixing guide for exporting and mixing nutrients from a storage tank;

[0006] A filter assembly for filtering impurities in drip irrigation liquid, wherein a diversion pipe is fixedly installed on the outer surface of the filter assembly.

[0007] The mixing guide is fixedly installed at the bottom of the storage tank and extends through the storage tank into its cavity. The filter assembly is fixedly installed on the outer surface of the mixing guide.

[0008] The filtration assembly includes a double-ended connecting pipe. Liquid collection pipes are fixedly installed on the outer surfaces of the double-ended connecting pipes. A protective cap is installed on the top of each liquid collection pipe. A flow guide seat is fixedly installed inside each liquid collection pipe, and a filter element is fixedly installed inside the flow guide seat. Workers connect the water pipe to the flow guide pipe to inject water into the storage tank. Nutrients are then added to the storage tank through the inlet. The irrigation equipment is then activated, causing the nutrient solution to mix with the liquid via a mixing guide before being filtered by the filtration assembly. The liquid is then directed to the plastic pipe connected to the diversion pipe for drip irrigation of the potatoes.

[0009] Preferably, the double-ended connecting pipe is fixedly installed on the outer surface of the mixing guide. Two liquid collection pipes are provided, each fixedly installed on the outer surface of the double-ended connecting pipe. A delivery pipe is fixedly installed at the bottom of each liquid collection pipe, and the delivery pipe is fixedly connected to the diverting pipe. Liquid is transported through the through-pipe into the double-ended connecting pipe, and then flows into the liquid collection pipe. After being filtered by the filter element and the guide seat, the liquid flows into the delivery pipe to filter impurities in the liquid, preventing impurities from clogging the plastic pipes and affecting drip irrigation efficiency.

[0010] Preferably, the flow guide includes a layered cover, the bottom of which has an outlet, a filter tube is fixedly installed on the top of which is fixedly installed inside the layered cover, and a support ring is fixedly installed on the top of the filter tube.

[0011] Preferably, the layered cover is fixedly installed at the bottom of the inner wall of the liquid collection pipe, the support ring is fixedly installed at the bottom of the filter element, and an inclined ring is fixedly installed on the inner wall of the layered cover, with the inclined ring located outside the support ring. Liquid is injected into the layered cover through the guide pipe, and the filter pipe inside the layered cover filters the liquid again, allowing the filtered liquid to flow from the outlet into the delivery pipe. This facilitates the removal of impurities from the liquid during delivery, reducing the impurity content and preventing scaling from forming on the pipes over long-term operation, which could lead to blockages in the plastic pipes during drip irrigation.

[0012] Preferably, the filter element includes a chassis, and four guide pipes are fixedly installed on the bottom of the chassis, which are distributed in a circumferential shape on the bottom of the chassis.

[0013] Preferably, a sleeve is fixedly installed on the side of the upper surface of the chassis, and a fixed seat is fixedly installed at the center of the upper surface of the chassis. A sliding column is fixedly installed on the top of the fixed seat, and a lower drain cover is fitted on the outer surface of the sliding column. Liquid is introduced into the sleeve through the injection pipe. At this time, the downward flowing liquid impacts downward, causing the lower drain cover to slide on the surface of the sliding column. The lower drain cover is made of flexible material. When sliding on the surface of the sliding column, the lower drain cover deforms and protrudes downward. At this time, the liquid is filtered through the holes on the lower drain cover to the surface of the chassis, and the liquid is diverted through the guide pipe to the guide seat, so that the liquid can be initially filtered through the lower drain cover. Multiple guide pipes increase the liquid flow path and prevent the liquid from clogging when passing through the lower drain cover.

[0014] Preferably, the lower drain cover is fixedly installed on the surface of the housing near the sliding column, and the lower drain cover is slidably adapted to the sliding column. A curved cover is fixedly installed at the top edge of the housing, and an injection tube is fixedly installed on the top of the curved cover. Four injection tubes are provided, and the four injection tubes are distributed in a circumferential shape on the top of the curved cover.

[0015] Preferably, the mixing guide includes a through pipe that penetrates the storage tank and extends into its cavity. A slip ring is fitted onto the outer surface of the through pipe, and a circular pad is fixedly installed on the outer surface of the slip ring. A stirring rotor is rotatably mounted on the outer surface of the circular pad, and an extension frame is fixedly installed on the outer surface of the stirring rotor. When the operator opens the valve at the mixing guide and the filter assembly, the liquid in the storage tank flows towards the filter assembly. When the liquid flows towards the through pipe, it first contacts the stirring rotor, causing the stirring rotor to rotate at the end of the through pipe. Since the extension frame is located on both sides of the outer surface of the circular ring and is rotatably positioned inside the cavity of the storage tank via the ring, the water flow pushes the extension frame, causing it to rotate with the ring due to the liquid flow, thus facilitating the mixing of the liquid in the storage tank and ensuring a more uniform mixing of the nutrients within the liquid.

[0016] Preferably, the stirring component includes a ring, with four curved frames fixedly mounted on its outer surface. Each of the four curved frames has a collar fixedly mounted on its surface, and the collars are fixedly connected to an extension frame. Two sets of inclined rods are fixedly mounted on the surface of the ring, symmetrically arranged around the ring. The curved frames separate the ring from the collars to divert the flowing liquid. When the liquid impacts the ring, the extension frame is propelled by the water flow, causing the ring to rotate and agitate the flowing liquid, thus facilitating uniform mixing of the nutrient solution and the liquid.

[0017] Preferably, the tilting rod is rotatably mounted on the surface of the circular pad on the side away from the ring. A folding rod is fixedly installed inside the tilting rod, and a clamping plate is fixedly installed between the opposite faces of the folding rod on the side away from the tilting rod. The clamping plate is rotatably mounted on the inner wall of the circular pad. The tilting rod and the clamping plate are clamped on both sides of the circular pad. When the extension frame drives the ring to rotate, the tilting rod and the clamping plate rotate on the surface of the circular pad to maintain the stability of the ring during rotation.

[0018] This invention provides a drip irrigation device for potato cultivation in sandy soil. It has the following beneficial effects:

[0019] 1. This drip irrigation equipment for potato cultivation in sandy areas injects liquid into a layered hood through a guide pipe. The filter pipe installed inside the layered hood filters the liquid again, allowing the filtered liquid to flow from the outlet into the delivery pipe. This helps to remove impurities from the liquid during delivery, reducing the impurity content in the liquid and preventing scaling from forming on the pipes over a long period of time, which would otherwise clog the plastic pipes during drip irrigation.

[0020] II. This drip irrigation equipment for potato cultivation in sandy areas introduces liquid into the casing through the injection pipe. The downward-flowing liquid impacts the lower drain cover, causing it to slide on the surface of the sliding column. The lower drain cover is made of flexible material, and deforms and protrudes downward as it slides on the sliding column surface. At this time, the liquid is screened through the holes on the lower drain cover to the surface of the base plate, and the liquid is diverted through the guide pipe to the guide seat, so that the liquid can be initially filtered through the lower drain cover. Multiple guide pipes increase the liquid flow path and prevent blockage when the liquid passes through the lower drain cover.

[0021] 3. The drip irrigation equipment used for potato cultivation in sandy areas allows the liquid in the storage tank to flow towards the filter component by opening the valves at the mixing guide and filter assembly. When the liquid flows towards the through pipe, it first comes into contact with the stirring rotor, causing the stirring rotor to rotate at the end of the through pipe. Since the extension frame is set on both sides of the outer surface of the ring and is set inside the cavity of the storage tank by the rotation of the ring, the water flow pushes the extension frame, causing the extension frame to swing with the ring due to the influence of the liquid flow, so as to mix the liquid in the storage tank and make the nutrients in the liquid more evenly mixed.

[0022] IV. The drip irrigation equipment used for potato cultivation in sandy areas uses a curved frame to separate the circular ring and the inner ring to divert the flowing liquid. When the liquid impacts the circular ring, the extended frame is pushed by the water flow to rotate the circular ring, thereby agitating the flowing liquid so that the nutrients and liquid can be mixed evenly.

[0023] 5. The drip irrigation equipment used for potato cultivation in sandy areas is secured to both sides of a circular pad by tilting rods and clamping plates. When the extension frame drives the circular ring to rotate, the tilting rods and clamping plates rotate on the surface of the circular pad to maintain the stability of the circular ring during rotation.

A liquid guide pipe 1 is fixedly installed on the top of the liquid storage tank 2, an injection port 6 is fixedly installed on one side of the outer surface of the liquid storage tank 2, and a support frame 3 is fixedly installed on the bottom of the liquid storage tank 2.

[0036] Mixing guide 7, which is used for mixing and exporting nutrients from the storage tank;

[0037] Filter assembly 4 is used to filter impurities in drip irrigation liquid, and a diversion pipe 5 is fixedly installed on the outer surface of the filter assembly 4.

[0038] The mixing guide 7 is fixedly installed at the bottom of the storage tank 2, and the mixing guide 7 extends through the storage tank 2 into its cavity. The filter assembly 4 is fixedly installed on the outer surface of the mixing guide 7.

[0039] The filter assembly 4 includes a double-ended connecting pipe 42, on the outer surface of which a liquid collection pipe 44 is fixedly installed. A protective cover 41 is installed on the top of each liquid collection pipe 44, and a flow guide seat 45 is fixedly installed inside the liquid collection pipe 44. A filter element 46 is fixedly installed inside the flow guide seat 45. The operator connects the water pipe to the liquid guide pipe 1 to inject water into the storage tank 2, and then adds the nutrient solution through the inlet 6 into the storage tank 2. The operator then starts the irrigation equipment, causing the solution and liquid to mix under the mixing guide 7 before being filtered through the filter assembly 4 to guide the liquid flow. The liquid is then drained from the plastic pipe connected to the diversion pipe 5 to drip irrigate the potatoes.

[0040] Preferably, the double-ended connecting pipe 42 is fixedly installed on the outer surface of the mixing guide 7. Two collection pipes 44 are provided, each fixedly installed on the outer surface of the double-ended connecting pipe 42. A delivery pipe 43 is fixedly installed at the bottom of each collection pipe 44, and the delivery pipe 43 is fixedly connected to the diversion pipe 5. Liquid is transported through the through pipe 71 into the double-ended connecting pipe 42, and then flows into the collection pipe 44. After being filtered by the filter element 46 and the guide seat 45, the liquid flows into the delivery pipe 43 to filter impurities in the liquid, preventing impurities from clogging the plastic pipes and affecting drip irrigation efficiency.

[0041] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 5 to 6 As shown, preferably, the flow guide seat 45 includes a layered cover 454, the bottom of the layered cover 454 is provided with an outlet 451, the top of the outlet 451 is fixedly installed with a filter tube 455, the filter tube 455 is fixedly installed inside the layered cover 454, and the top of the filter tube 455 is fixedly installed with a support ring 452.

[0042] Preferably, the layered cover 454 is fixedly installed on the bottom of the inner wall of the liquid collection pipe 44, the support ring 452 is fixedly installed on the bottom of the filter element 46, and an inclined ring 453 is fixedly installed on the inner wall of the layered cover 454, with the inclined ring 453 located outside the support ring 452. Liquid is injected into the layered cover 454 through the guide pipe 466, and the filter pipe 455 installed inside the layered cover 454 filters the liquid again, allowing the filtered liquid to flow from the outlet 451 into the delivery pipe 43. This facilitates the removal of impurities from the liquid during delivery, reducing the impurity content and preventing scaling during long-term pipe operation, which could lead to impurities clogging the plastic pipe during drip irrigation.

[0043] Preferably, the filter element 46 includes a chassis 468, and a guide pipe 466 is fixedly installed on the bottom of the chassis 468. Four guide pipes 466 are provided and are distributed in a circumferential shape on the bottom of the chassis 468.

[0044] Preferably, a housing 465 is fixedly installed on the side of the upper surface of the chassis 468, and a fixing seat 467 is fixedly installed at the center of the upper surface of the chassis 468. A sliding column 463 is fixedly installed on the top of the fixing seat 467, and a lower drain cover 464 is fitted on the outer surface of the sliding column 463. Liquid is introduced into the housing 465 through the injection pipe 462. At this time, the downward flowing liquid impacts downward, causing the lower drain cover 464 to slide on the surface of the sliding column 463. The lower drain cover 464 is made of flexible material. When sliding on the surface of the sliding column 463, the lower drain cover 464 deforms and protrudes downward. At this time, the liquid is filtered through the holes on the lower drain cover 464 to the surface of the chassis 468, and the liquid is diverted through the guide pipe 466 to the guide seat 45, so that the liquid can be initially filtered through the lower drain cover 464. The multiple guide pipes 466 increase the liquid flow path and prevent the liquid from clogging when passing through the lower drain cover 464.

[0045] Preferably, the lower drain cover 464 is fixedly installed on the surface of the housing 465 near the sliding column 463, and the lower drain cover 464 is slidably adapted to the sliding column 463. A curved cover 461 is fixedly installed at the top edge of the housing 465, and an injection tube 462 is fixedly installed on the top of the curved cover 461. Four injection tubes 462 are provided, and the four injection tubes 462 are distributed in a circumferential shape on the top of the curved cover 461.

[0046] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 7 to 9 As shown, preferably, the mixing guide 7 includes a through pipe 71 that penetrates the storage tank 2 and extends into its cavity. A slip ring 72 is fitted on the outer surface of the through pipe 71, and a circular pad 75 is fixedly installed on the outer surface of the slip ring 72. A stirring rotor 73 is rotatably installed on the outer surface of the circular pad 75, and an extension frame 74 is fixedly installed on the outer surface of the stirring rotor 73. When the operator opens the valve at the mixing guide 7 and the filter assembly 4, the liquid in the storage tank 2 flows towards the filter assembly 4. When the liquid flows towards the through pipe 71, it first contacts the stirring rotor 73, causing the stirring rotor 73 to rotate at the end of the through pipe 71. Since the extension frame 74 is located on both sides of the outer surface of the circular ring 732 and is rotatably positioned inside the cavity of the storage tank 2 through the circular ring 732, the water flow pushes the extension frame 74, causing the extension frame 74 to rotate with the circular ring 732 due to the influence of the liquid flow, thereby facilitating the mixing of the liquid in the storage tank 2 and making the nutrients in the liquid more evenly mixed.

[0047] Preferably, the stirring component 73 includes a ring 732, with four bent frames 731 fixedly mounted on the outer surface of the ring 732. Each of the four bent frames 731 has a collar 736 fixedly mounted on its surface, and the collar 736 is fixedly connected to an extension frame 74. Two sets of inclined rods 733 are fixedly mounted on the surface of the ring 732, symmetrically arranged around the ring 732. The bent frames 731 separate the ring 732 from the collars 736 to divert the flowing liquid. When the liquid impacts the ring 732, the extension frame 74 is propelled by the water flow, causing the ring 732 to rotate, thus agitating the flowing liquid and facilitating uniform mixing of the nutrient solution and the liquid.

[0048] Preferably, the tilting rod 733 is rotatably mounted on the surface of the circular pad 75 on the side away from the ring 732. A folding rod 734 is fixedly mounted inside the tilting rod 733. A retaining plate 735 is fixedly mounted between the opposite faces of the folding rod 734 on the side away from the tilting rod 733. The retaining plate 735 is rotatably mounted on the inner wall of the circular pad 75. The tilting rod 733 and the retaining plate 735 are engaged on both sides of the circular pad 75. When the extension frame 74 drives the ring 732 to rotate, the tilting rod 733 and the retaining plate 735 rotate on the surface of the circular pad 75 to maintain the stability of the ring 732 during rotation.

[0049] In use, the staff connects the water pipe to the liquid guide pipe 1 to inject water into the storage tank 2, and puts the nutrient agent into the storage tank 2 through the injection port 6. Then, the staff starts the irrigation equipment so that the agent and liquid are mixed by the mixing guide 7 and then filtered through the filter assembly 4 to guide the liquid flow, so that the liquid is discharged from the plastic pipe connected to the diversion pipe 5 to drip irrigate the potatoes.

[0050] The liquid is transported through the through-pipe 71 to the double-ended connecting pipe 42, and then the liquid is introduced into the collection pipe 44 through the double-ended connecting pipe 42. After being filtered by the filter element 46 and the guide seat 45, the liquid flows into the delivery pipe 43 to filter impurities in the liquid and prevent impurities from clogging the plastic pipe and affecting the drip irrigation efficiency.

[0051] Liquid is injected into the layered cover 454 through the guide pipe 466. The filter pipe 455 installed in the layered cover 454 filters the liquid again, so that the filtered liquid flows from the outlet 451 into the delivery pipe 43. This is to remove impurities in the liquid during liquid delivery, reduce the impurity content in the liquid, and avoid scaling in the pipeline during long-term operation, which would cause impurities to clog the plastic pipe during drip irrigation.

[0052] Liquid flows into housing 465 through injection pipe 462. The downward-flowing liquid impacts the lower drain cover 464, causing it to slide on the surface of slide column 463. The lower drain cover 464 is made of flexible material. When sliding on the surface of slide column 463, the lower drain cover 464 deforms and protrudes downward. At this time, the liquid is filtered through the holes on the lower drain cover 464 to the surface of chassis 468, and the liquid is diverted through guide pipe 466 to guide seat 45, so that the liquid can be initially filtered through the lower drain cover 464. The multiple guide pipes 466 increase the liquid flow path and prevent the liquid from clogging when passing through the lower drain cover 464.

[0053] The operator opens the valves at the mixing guide 7 and the filter assembly 4, causing the liquid in the storage tank 2 to flow towards the filter assembly 4. When the liquid flows towards the through pipe 71, it first comes into contact with the stirring rotor 73, causing the stirring rotor 73 to rotate at the end of the through pipe 71. Since the extension frame 74 is set on both sides of the outer surface of the ring 732 and is rotated inside the cavity of the storage tank 2 through the ring 732, the water flow pushes the extension frame 74, causing the extension frame 74 to swing with the ring 732 due to the influence of the liquid flow, so as to mix the liquid in the storage tank 2 and make the nutrients in the liquid more evenly mixed.

[0054] The bending frame 731 separates the ring 732 and the collar 736 to divert the flowing liquid. When the liquid impacts the ring 732, the extension frame 74 is pushed by the water flow to rotate the ring 732, thereby agitating the flowing liquid so that the nutrient agent and the liquid can be mixed evenly.

[0055] The tilting rod 733 and the clamping plate 735 are clamped on both sides of the circular pad 75. When the extension frame 74 drives the ring 732 to rotate, the tilting rod 733 and the clamping plate 735 rotate on the surface of the circular pad 75 to maintain the stability of the ring 732 during rotation.

[0056] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
