Description

Technical Field

[0001] This invention relates to the field of drip irrigation technology in landscaping, and in particular to a drip irrigation water-saving device for landscaping. Background Technology

[0002] Drip irrigation is a water-saving irrigation method that delivers water and nutrients to the crop root zone slowly and evenly, drop by drop, through a pipeline system and sprinklers installed on capillary tubes, according to the crop's water requirements. Drip irrigation does not damage the soil structure, and the water, fertilizer, air, and heat within the soil are constantly maintained in a state suitable for crop growth. It has minimal evaporation loss, does not produce surface runoff, and has almost no deep seepage, making it a water-saving irrigation method.

[0003] Current drip irrigation systems have several drawbacks. They cannot accurately deliver water to the inside of the flowerpot, resulting in poor drip irrigation precision and affecting the irrigation effect. Therefore, accurately delivering water to the inside of the flowerpot can improve the accuracy of drip irrigation, thereby increasing the irrigation effect and ultimately achieving water conservation.

[0004] Chinese patent document CN210226464U discloses a water-saving drip irrigation device for garden flower planting, including a precision drip irrigation mechanism. The precision drip irrigation mechanism includes a fixed rod, a first connecting plate fixed to one side of the fixed rod, a second connecting plate fixed to the bottom of the first connecting plate, a sliding rod fixed to the back of the first connecting plate, a sliding sleeve sleeved to the outside of the sliding rod, the sliding sleeve slidably connected to the sliding rod, a connecting rod fixed to the bottom of the sliding sleeve, a water storage tank at the bottom of the connecting rod, a positioning rod at the bottom of the water storage tank, a universal water pipe fixed to the bottom of the positioning rod, a pointing pipe fixed to the bottom of the universal water pipe, a drip irrigation head at the bottom of the pointing pipe, a connecting pipe on one side of the universal water pipe, and an infusion tube with flow adjustment on the outside of the connecting pipe. The device includes a connecting pipe that passes through the water tank and extends into it. Multiple sliding sleeves are provided, each with a stretching band on one side and an adjustment mechanism at the top. The adjustment mechanism includes a drive rod, a slider at the top of the drive rod, an electric slide rail at the top of the slider, and a top plate at the top of the electric slide rail. The top plate is welded to a first connecting plate. A water inlet pipe is located at the top of the water tank, with a main water inlet pipe at one end and a water pump at the other end. The water pump is fixedly connected to the first connecting plate, and has an inlet pipe on one side. By setting the adjustment mechanism, the spacing between the drip irrigation heads can be effectively adjusted, allowing for adjustments to the density of the drip irrigation heads as needed, further improving the convenience and precision of drip irrigation.

[0005] While this patent allows for precise drip irrigation of plants in practical use, it fails to protect the bottom of the drip head. When the drip head is not in use, prolonged exposure may damage it, ultimately preventing the device from effectively irrigating the plants. Summary of the Invention

[0006] The main objective of this invention is to provide a drip irrigation water-saving device for landscaping that can effectively solve the problem of not being able to protect the bottom of the drip irrigation head.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] A water-saving drip irrigation device for landscaping includes a base plate and two sliding columns. The base plate has casters at its four corners. A collection housing is located at the top of the base plate, and a filter plate is located inside the collection housing. Mounting plates are located at the center of both ends of the collection housing. Multiple through slots are formed on the upper part of the mounting plates. Multiple drip irrigation devices are located on the outer surface of both mounting plates. Each drip irrigation device has a first flexible hose near the collection housing, and all first flexible hoses communicate with the collection housing. The ends of the two sliding columns near the collection housing are fixedly connected to the collection housing.

[0009] Preferably, the drip irrigation device includes a first support plate and a second hose. The side of the first support plate closest to the mounting plate is slidably connected to the mounting plate. The side of the first support plate closest to the collecting housing is provided with two first threaded rods, and two bolts are provided on the outer surface of the two first threaded rods. Both first threaded rods can pass through multiple through slots. A fixing block is provided at the lower part of the end of the first support plate closest to the collecting housing. Multiple fixing blocks are slidably connected to sliding columns on the same side. A fixing housing is provided at the upper part of the first support plate. A synchronization component is provided in the middle of the fixing housing. The front and rear parts of the synchronization component are slidably connected to the fixing housing. The side of the second hose closest to the collecting housing is fixedly connected to the first hose. A second support plate is provided at the lower end of the fixing housing away from the first support plate. A fixing column is provided at the lower part of the second support plate. An adjustment component is provided on the outer surface of the fixing column. The lower part of the adjustment component communicates with the second hose.

[0010] Preferably, the adjustment assembly includes multiple moving blocks and multiple drip heads. Each of the multiple moving blocks has a movable plate on its upper part. Two movable plates have a common rotating shaft on their adjacent sides. Each of the multiple moving blocks has a mounting block at its lower end. The middle of each of the multiple mounting blocks is slidably connected to a fixed column. The interior of each of the multiple mounting blocks is fixedly connected to a drip head on the same side. One side of each of the multiple moving blocks has a common second threaded rod. The other side of each of the multiple moving blocks has a limiting column. The left and right ends of the limiting column are fixedly connected to a second support plate and a first support plate, respectively.

[0011] Preferably, the synchronization component includes a third threaded rod and multiple slide rails. The lower end of the third threaded rod is provided with a lifting plate. The third threaded rod passes through the upper part of the fixed housing. The front and rear ends of the lifting plate are slidably connected to the fixed housing. There are through-posts at the four corners of the lower end of the lifting plate. The upper parts of the multiple slide rails are slidably connected to the fixed housing. The rear ends of the multiple slide rails are fixedly connected to multiple moving blocks. The inner surface of the multiple slide rails is provided with a moving plate. The rear part of the multiple moving plates is provided with a linkage groove. The left and right sides of the inner surface of the multiple linkage grooves are provided with linkage posts. The rear ends of the multiple linkage posts are provided with driven plates. The upper part of the moving plates is provided with a linkage plate. The upper parts of the multiple linkage plates are slidably connected to the lower part of the lifting plate. The ends of the multiple linkage plates that are close to each other are provided with a telescopic rod. The upper parts of the multiple baffles are slidably connected to the lower part of the mounting block on the same side. The middle of the rear ends of the multiple slide rails is provided with a limiting plate. The middle of the multiple limiting plates is provided with a transverse groove. The multiple through grooves are slidably connected to the multiple linkage posts.

[0012] Preferably, both of the first threaded rods can pass through multiple through slots.

[0013] Preferably, the linkage plate is L-shaped.

[0014] Preferably, the lower part of the insertion post is tapered.

[0015] Preferably, the driven plate has a Z-shaped shape.

[0016] Preferably, the linkage groove is V-shaped.

[0017] Preferably, the plurality of limiting plates are C-shaped.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In this invention, rainwater can be filtered using a filter plate, thereby collecting water resources. When the position of the drip irrigation device needs to be changed, pushing the fixed housing will cause the drip irrigation device to slide on the outer surface of the mounting plate. After the position of the drip irrigation device is determined, it is fixed using two first threaded rods and two bolts, thereby determining the position of the drip irrigation device and drip irrigating the plants, ultimately achieving water conservation.

[0020] In this invention, the adjustable components allow for more precise drip irrigation positioning. Rotating the second threaded rod moves multiple moving blocks, thereby moving multiple drip irrigation heads to irrigate the plants. Once the irrigation position is determined, a synchronization component inserts multiple insertion posts into the soil to secure the device and prevent movement during irrigation. This also allows the two baffles to move away from each other, enabling drip irrigation. After irrigation, to prevent damage to the drip irrigation heads, the two baffles are brought closer together to protect them and prevent damage that could render the device unusable.

[0032] 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. Example 1

[0033] like Figure 1 As shown, a drip irrigation water-saving device for landscaping includes a base plate 6 and two sliding columns. The device is characterized by: universal wheels 5 at the four corners of the lower end of the base plate 6; a collection housing 1 at the upper end of the base plate 6; a filter plate 2 inside the collection housing 1; mounting plates 3 at the middle of both ends of the collection housing 1; multiple through slots on the upper part of the mounting plates 3; multiple drip irrigation devices 4 on the outer surface of both mounting plates 3; a first flexible hose 7 on the side of each drip irrigation device 4 near the collection housing 1; multiple first flexible hoses 7 communicating with the collection housing 1; and a fixed connection between the ends of the two sliding columns near the collection housing 1.

[0034] First, the device can be moved to a suitable position using the multiple casters 5. Then, water is poured into the collection housing 1. The filter plate 2 can filter the water and also filter rainwater in rainy weather, thus collecting water resources. At the same time, the multiple drip irrigation devices 4 are slidably connected to the mounting plate 3. In order to make the device more versatile, the position of the drip irrigation device 4 can be changed using the mounting plate 3, so as to accurately drip irrigate plants in different locations, reduce water waste, and ultimately increase the functionality of the device. The multiple first hoses 7 can deliver water to the drip irrigation device 4, thereby drip irrigating the plants.

[0035] like Figure 2 - Figure 3As shown, the drip irrigation device 4 includes a first support plate 44 and a second hose 45. The side of the first support plate 44 closest to the mounting plate 3 is slidably connected to the mounting plate 3. The side of the first support plate 44 closest to the collecting housing 1 is provided with two first threaded rods 41, each of which can pass through multiple through slots. The outer surface of the two first threaded rods 41 is provided with two bolts 42. The lower part of the end of the first support plate 44 closest to the collecting housing 1 is provided with a fixing block 43. Multiple fixing blocks 43 are slidably connected to sliding columns on the same side. The upper end of the first support plate 44 is provided with a fixing housing 40. The middle part of the fixing housing 40 is provided with a synchronization component 49. The front and rear parts of the synchronization component 49 are slidably connected to the fixing housing 40. The side of the second hose 45 closest to the collecting housing 1 is fixedly connected to the first hose 7. The lower end of the fixing housing 40 away from the first support plate 44 is provided with a second support plate 47. The lower part of the second support plate 47 is provided with a fixing column 46. The outer surface of the fixing column 46 is provided with an adjustment component 48. The lower part of the adjustment component 48 is connected to the second hose 45.

[0036] When the position of the drip irrigation device 4 needs to be changed, the fixed housing 40 can be pushed to allow the drip irrigation device 4 to slide on the outer surface of the mounting plate 3. After the position of the drip irrigation device 4 is determined, the drip irrigation device 4 is fixed by the two first threaded rods 41 and the two bolts 42, thus determining the position of the drip irrigation device 4. At the same time, the position of the drip irrigation device can be further adjusted by the adjustment component 48, so as to better irrigate the plants. After the position of the drip irrigation device is adjusted, the drip irrigation device 4 can be fixed by the synchronization component 49 to prevent the drip irrigation device 4 from moving during the drip irrigation process and affecting the drip irrigation effect. Multiple second hoses 45 are connected to the adjustment component 48, so water will be delivered from the first hose 7 to the lower part of the adjustment component 48, thereby irrigating the plants.

[0037] like Figure 4 As shown, the adjustment assembly 48 includes multiple moving blocks 480 and multiple drip heads 484. Each of the multiple moving blocks 480 has a movable plate 481 on its upper part. Two movable plates 481 are provided with a common rotating shaft on their side that is close to each other. Each of the multiple moving blocks 480 has a mounting block 482 at its lower end. The middle of the multiple mounting blocks 482 is slidably connected to a fixed column 46. The interior of each of the multiple mounting blocks 482 is fixedly connected to the drip head 484 on the same side. One side of the multiple moving blocks 480 is provided with a second threaded rod 483. The other side of the multiple moving blocks 480 is provided with a limiting column. The left and right ends of the limiting column are fixedly connected to a second support plate 47 and a first support plate 44, respectively.

[0038] When the position of the drip irrigation needs to be changed, rotating the second threaded rod 483 will cause multiple moving blocks 480 to move, which will cause multiple movable plates 481 to rotate. Since there is a rotating shaft on the side of the two movable plates 481 that are close to each other, a certain angle will be formed between the two movable plates 481. While the multiple moving blocks 480 are moving, they will also drive multiple mounting blocks 482 and drip irrigation head 484 to move, thereby changing the position of the drip irrigation.

[0039] Figure 4 The state in the middle is when multiple moving blocks 480 are far apart from each other, and at this time multiple moving plates 481 are in the extended state;

[0040] Figure 5 The state in the middle is when multiple moving blocks 480 are close to each other. At this time, multiple moving plates 481 are in a compressed state, so as to drip irrigation at different positions, ultimately making the device more versatile.

[0041] like Figure 6 - Figure 8 The synchronization component 49 includes a third threaded rod 490 and multiple slide rails 493. A lifting plate 491 is provided at the lower end of the third threaded rod 490. The third threaded rod 490 passes through the upper part of the fixed housing 40. The front and rear ends of the lifting plate 491 are slidably connected to the fixed housing 40. Insertion posts 492 are provided at the four corners of the lower end of the lifting plate 491. The upper parts of the multiple slide rails 493 are slidably connected to the fixed housing 40. The rear ends of the multiple slide rails 493 are fixedly connected to multiple moving blocks 480. Moving plates 496 are provided on the inner surfaces of the multiple slide rails 493. Linkage grooves 497 are opened at the rear of the multiple moving plates 496. Linkage posts 498 are provided on the left and right sides of the inner surfaces of the multiple linkage grooves 497. Each of the multiple linkage columns 498 has a driven plate 499 at its rear end, and a linkage plate 494 is provided at the upper end of the moving plate 496. The upper parts of the multiple linkage plates 494 are slidably connected to the lower part of the lifting plate 491. The ends of the multiple linkage plates 494 that are close to each other are provided with a telescopic rod 495. The linkage groove 497 is V-shaped, the linkage plate 494 is L-shaped, the lower part of the through column 492 is conical, the driven plate 499 is Z-shaped, the upper parts of the multiple baffles 4000 are slidably connected to the lower part of the mounting block 482 on the same side, the middle of the rear end of the multiple slide rails 493 is provided with a limiting plate, the middle of the multiple limiting plates is provided with a transverse groove, and the multiple through grooves are slidably connected to the multiple linkage columns 498.

[0042] Once the drip irrigation location is determined, rotating the third threaded rod 490 will cause the lifting plate 491 to move downwards, which in turn will cause the multiple inserted columns 492 to move downwards, thus inserting the multiple inserted columns 492 into the soil and fixing the device. This allows movement during drip irrigation. As the lifting plate 491 moves downwards, it will cause the multiple linkage plates 494 to move downwards, which will cause the moving plate 496 to move downwards. This will cause the two linkage columns 498 to contact different positions on the inner surface of the linkage groove 497, thereby causing the two driven plates 499 and the baffle 4000 to move away from each other. At this time, the lower part of the drip irrigation head 484 will not be blocked, thus drip irrigation of the plants will be carried out. When the multiple moving blocks 480 move, they will cause the multiple slides 493 to move, which will cause the multiple linkage plates 494 to slide under the lifting plate 491, thus not affecting the operation of the device.

[0043] Figure 6 The multiple interlocking posts 492 are not inserted into the soil, and the multiple baffles 4000 are closed to each other. At this time, the multiple drip irrigation heads 484 cannot drip irrigate the plants, thus protecting the multiple drip irrigation heads 484 and preventing them from being damaged.

[0044] like Figure 9 - Figure 10 As shown, the multiple insertion columns 492 can be inserted into the soil, thus improving the drip irrigation effect and preventing the device from moving. At the same time, the multiple baffles 4000 are moved away from each other, and the multiple baffles 4000 no longer block the lower part of the insertion columns 492. At this time, the multiple drip irrigation heads 484 can be used to drip irrigate the plants. When the linkage plate 494 moves downward, it will drive the moving plate 496 to move downward, so that the two linkage columns 498 contact the upper part of the linkage groove 497, thereby moving the two driven plates 499 and the baffles 4000 away from each other. At this time, the plants can be drip irrigated. If the device is not used for drip irrigation, rotating the third threaded rod 490 will move the lifting plate 491 upward, which will drive the moving plate 496 upward, thereby bringing the two driven plates 499 and the baffles 4000 closer together, thus blocking the lower part of the insertion columns 492, which can protect the drip irrigation heads 484.

[0045] The specific implementation method is as follows: First, the device is moved to a suitable position, and then the inside of the collection housing 1 is filled with water. During rainy days, water can be collected, and the filter plate 2 can also filter the rainwater. Next, if the position of multiple drip irrigation devices 4 needs to be adjusted, multiple first threaded rods 41 and multiple bolts 42 can be used to fix the moved position. Then, the position of multiple moving blocks 480 can be moved using the adjustment component 48, thereby changing the drip irrigation position and ultimately achieving precise drip irrigation. Rotating the second threaded rod 483 will cause multiple moving blocks 480 to move, which will cause multiple movable plates 481 to rotate. Since the two movable plates 481 have a rotating shaft on their adjacent sides, a certain angle will be formed between the two movable plates 481. While the multiple moving blocks 480 move, they will also drive multiple mounting blocks 482 and drip irrigation heads 484 to move. After determining the drip irrigation position, rotating the third threaded rod 490 will cause the lifting plate 491 to move downwards. This causes multiple insertion columns 492 to move downwards, inserting them into the soil and fixing the device in place. During drip irrigation, the lifting plate 491 moves downwards, causing multiple linkage plates 494 to move downwards, which in turn causes the moving plate 496 to move downwards. This brings two linkage columns 498 into contact with different positions on the inner surface of the linkage groove 497, causing the two driven plates 499 and the baffle 4000 to move away from each other. This prevents obstruction of the lower part of the drip head 484, allowing for drip irrigation of the plants. After irrigation, to prevent damage to the drip head 484, the two baffles 4000 can be brought closer together to protect it and prevent damage that could render the device unusable. Once the position of the drip head 484 is confirmed, water from inside the collection housing 1 can be drawn into the first hose 7 and the second hose 45, allowing water to drip from the multiple drip heads 484 and ultimately irrigate the plants.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
