Description

Technical Field

[0001] This utility model relates to the field of green plant maintenance technology, specifically a drip irrigation device for green plant maintenance. Background Technology

[0002] Most green plants prefer slightly moist soil but are intolerant of waterlogging, so it's important to carefully control the amount of water when watering. Water when the soil is dry to the touch, keeping it slightly moist, especially during the peak growing season. Drip irrigation avoids water movement in the air, doesn't wet the leaves, and doesn't cause evaporation beyond the effective moistened area of ​​the soil surface, thus minimizing direct water loss through evaporation. It's also easy to control the amount of water, preventing surface runoff and deep soil seepage, making it suitable for green plant care.

[0003] According to a public notice (No. CN219046931U) of a drip irrigation device for urban greening, the aforementioned application includes a support plate, a conical block, and a mating plate. When installing the hose, rotating the knob causes the screw to rotate, which in turn moves the transmission plate. The movement of the transmission plate then moves the connecting plate, which in turn moves the support plate. The movement of the support plate then moves the conical block, thus changing the gap between the conical block and the mating plate. This allows for adjustment of the amount of water entering the hose from the main water pipe. This structure enables the drip irrigation water volume to be adjusted according to the density of the greenery during hose installation, thereby improving the drip irrigation effect of the device.

[0004] However, in actual use, the above-mentioned equipment can only control the water volume at the inlet. When it is necessary to accurately control the water volume of drip irrigation, it is difficult to accurately control the water volume of drip irrigation by only controlling the water volume of the main water pipe, which reduces the irrigation effect of the drip irrigation device. In view of this, we propose a drip irrigation device for green plant maintenance. Utility Model Content

[0005] The purpose of this invention is to provide a drip irrigation device for green plant maintenance to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drip irrigation device for green plant maintenance, comprising an inlet pipe, a valve fixedly connected to the outer wall of the inlet pipe, a drip irrigation pipe fixedly connected to the inner wall of the inlet pipe, a drip irrigation port opened on the outer wall of the drip irrigation pipe, and a limiting component disposed inside the inlet pipe, the limiting component comprising:

[0007] A fixed shell is fixedly connected to the outer wall of the drip irrigation pipe. A bolt is threadedly connected to the outer wall of the fixed shell. A connecting plate is slidably connected through the outer wall of the bolt. The end of the connecting plate away from the fixed shell is fixedly connected to the fixed plate.

[0008] A threaded rod is threadedly connected to the inner wall of a fixed housing. A knob is fixedly connected to the upper outer wall of the threaded rod, a limiting block is fixedly connected to the lower end of the threaded rod, an indicator plate is rotatably connected to the outer wall of the threaded rod, and a pointer is fixedly connected to the outer wall of the fixed housing.

[0009] Preferably, the threaded rod is internally provided with a flow guiding component, which includes a flow guiding rod that is threaded through and connected to the inner wall of the threaded rod. A rotating block is fixedly connected to the upper outer wall of the flow guiding rod, and a conical head is fixedly connected to the lower outer wall of the flow guiding rod. This allows the water flow to move along the flow guiding rod to the tip of the conical head during drip irrigation, making it easier for the water to condense into droplets before dripping. Furthermore, the position of the flow guiding rod can be controlled, allowing the water to drip more effectively onto the soil when the drip irrigation pipe is in a position that is difficult to move downwards.

[0010] Preferably, the outer wall of the threaded rod is provided with a limiting groove, the indicator plate is composed of a scale plate and a sliding plate, the sliding plate is slidably connected to the limiting groove, the scale plate is provided with a scale, the pointer is in contact with the scale, when the knob is rotated to make the threaded rod rotate and move in the fixed shell, the sliding plate slides and rises and falls in the limiting groove, thereby causing the indicator plate to rise and fall.

[0011] Preferably, in an embodiment of the present invention, the threaded rod passes through the drip inlet and is slidably connected to the inner wall of the drip inlet, and the limiting block is set in the shape of a frustum, with the larger end of the limiting block having the same area as the drip inlet, so that the limiting block can completely block the drip inlet when it is in full contact with it.

[0012] Preferably, the area of ​​the flat end of the conical head is the same as the area of ​​the guide rod, and the area of ​​the flat end of the conical head is the same as the area of ​​the smaller end of the limiting block, so that the water flow can be better guided from the guide rod to the conical head.

[0013] Preferably, both ends of the connecting plate are threaded with bolts, and one set of bolts is threadedly connected to the connecting plate and the fixed shell, while the other set of bolts is fixedly connected to the connecting plate and the fixed plate, so that the fixed plate and the fixed shell are fixed together by the connecting plate and the bolts.

[0014] Compared with the prior art, this utility model provides a drip irrigation device for green plant maintenance, which has the following beneficial effects:

[0015] 1. This drip irrigation device for green plant maintenance, by turning the knob to make the threaded rod rotate and move in the fixed shell, causes the limiting block to move, thereby controlling the distance between the limiting block and the drip irrigation nozzle, and thus controlling the water volume of the device. The sliding plate slides and rises and falls in the limiting groove, thereby causing the indicator plate to rise and fall. At this time, the scale pointed to by the pointer can represent the distance between the limiting block and the drip irrigation nozzle, allowing the user to accurately control the water volume of drip irrigation. When the limiting block is in complete contact with the drip irrigation nozzle, it can completely block the drip irrigation nozzle, preventing water from dripping from the drip irrigation nozzle, thereby allowing the number of working drip irrigation nozzles to be controlled.

[0016] 2. This drip irrigation device for green plant maintenance allows the water flow to move along the guide rod to the tip of the conical head by rotating the rotating block. This makes it easier for the water to condense into droplets before dripping. The position of the guide rod can be controlled. When the drip irrigation pipe is in a position that is difficult to move down, the guide rod can be used to make the water flow better onto the soil. This prevents the drip irrigation pipe from being too high, causing the dripping water droplets to be blown away by the wind and preventing the soil from being irrigated. Attached Figure Description

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: a drip irrigation device for green plant maintenance, including an inlet pipe 1, a valve 2 fixedly connected to the outer wall of the inlet pipe 1, a drip irrigation pipe 3 fixedly connected to the inner wall of the inlet pipe 1, a drip irrigation port 4 opened on the outer wall of the drip irrigation pipe 3, and a limiting component 5 set inside the inlet pipe 1. The limiting component 5 includes a fixing shell 51, a bolt 52, a connecting plate 53, a fixing plate 54, a knob 55, a threaded rod 56, a limiting block 57, an indicator plate 58, and a pointer 59.

[0023] In one embodiment of the present invention, the fixing shell 51 is fixedly connected to the outer wall of the drip irrigation pipe 3, the outer wall of the fixing shell 51 is threaded with a bolt 52, the outer wall of the bolt 52 is slidably connected with a connecting plate 53, and the end of the connecting plate 53 away from the fixing shell 51 is fixedly connected to the fixing plate 54.

[0024] In one embodiment of this utility model, the threaded rod 56 is threadedly connected to the inner wall of the fixed shell 51, a knob 55 is fixedly connected to the upper outer wall of the threaded rod 56, a limiting block 57 is fixedly connected to the lower end of the threaded rod 56, an indicator plate 58 is rotatably connected to the outer wall of the threaded rod 56, and a pointer 59 is fixedly connected to the outer wall of the fixed shell 51.

[0025] In addition, a flow guiding component 6 is provided inside the threaded rod 56. The flow guiding component 6 includes a flow guiding rod 62, which is threaded through and connected to the inner wall of the threaded rod 56. A rotating block 61 is fixedly connected to the upper outer wall of the flow guiding rod 62, and a conical head 63 is fixedly connected to the lower outer wall of the flow guiding rod 62. When the drip irrigation device is drip irrigating, the water flow will move along the flow guiding rod 62 to the tip of the conical head 63, making it easier for the water flow to condense into water droplets before dripping. The position of the flow guiding rod 62 can be controlled. When the drip irrigation pipe 3 is in a position that is difficult to move down, the flow guiding rod 62 can be used to make the water flow better drip onto the soil, preventing the drip irrigation pipe 3 from being too high and causing the dripping water droplets to be blown away by the wind, thus preventing the soil from being irrigated.

[0026] In this embodiment of the utility model, a limiting groove is provided on the outer wall of the threaded rod 56, and the indicator plate 58 is composed of a scale plate and a sliding plate. The sliding plate is slidably connected to the limiting groove, and a scale is provided on the scale plate. The pointer 59 is in contact with the scale. When the knob 55 is rotated to make the threaded rod 56 rotate and move in the fixed shell 51, the sliding plate slides and rises and falls in the limiting groove, thereby causing the indicator plate 58 to rise and fall. At this time, the scale pointed to by the pointer 59 can represent the distance between the limiting block 57 and the drip irrigation port 4, so that the user can accurately control the amount of water for drip irrigation.

[0027] In this embodiment of the utility model, the threaded rod 56 passes through the drip irrigation port 4 and is slidably connected to the inner wall of the drip irrigation port 4. The limiting block 57 is set in the shape of a frustum, and the larger end of the limiting block 57 is the same as the area of ​​the drip irrigation port 4. When the limiting block 57 is in complete contact with the drip irrigation port 4, it can completely block the drip irrigation port 4, so that the water flow will not drip from the drip irrigation port 4, thereby controlling the number of working drip irrigation ports 4.

[0028] In an embodiment of this utility model, the area of ​​the flat end of the conical head 63 is the same as the area of ​​the guide rod 62, and the area of ​​the flat end of the conical head 63 is the same as the area of ​​the smaller end of the limiting block 57, so that the water flow can be better guided from the guide rod 62 to the conical head 63, thereby making it easier for the water flow to condense into water droplets and fall.

[0029] In the embodiment of this utility model, both ends of the connecting plate 53 are threaded with bolts 52, and one set of bolts 52 is threadedly connected to the connecting plate 53 and the fixing shell 51, while the other set of bolts 52 is fixedly connected to the connecting plate 53 and the fixing plate 54, so that the fixing plate 54 and the fixing shell 51 are fixed together by the connecting plate 53 and the bolts 52, preventing the fixing shell 51 from falling off the drip irrigation pipe 3.

[0030] In this invention, during use, first rotating the knob 55 causes the threaded rod 56 to rotate and move within the fixed housing 51. This causes the sliding plate to slide and rise / fall within the limiting groove, thereby raising and lowering the indicator plate 58. At this time, the pointer 59 indicates the distance between the limiting block 57 and the drip irrigation port 4, allowing the user to precisely control the amount of water used for drip irrigation. When the limiting block 57 is fully in contact with the drip irrigation port 4, it completely blocks the port, preventing water from dripping. This allows the number of working drip irrigation ports 4 to be controlled. Rotate the rotating block 61 to adjust the position of the diversion rod 62. The water will flow along the diversion rod 62 to the tip of the conical head 63, making it easier for the water to condense into droplets before dripping. The position of the diversion rod 62 can be controlled. When the drip irrigation pipe 3 is in a position that is difficult to move down, the diversion rod 62 can be used to make the water flow better onto the soil, preventing the drip irrigation pipe 3 from being too high and causing the dripping water droplets to be blown away by the wind, thus preventing the soil from being irrigated. Afterwards, the valve 2 can be opened to allow water to flow from the inlet pipe 1 into the drip irrigation pipe 3, and then irrigate the green plants through the drip irrigation port 4.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
