Abstract
Description
Technical Field
[0001] The utility model relates to agricultural planting technology, in particular to a water-saving irrigation device for crops. Background Art
[0002] In agricultural irrigation, drip irrigation is gradually being promoted to save water and improve irrigation efficiency. According to tests, the average water consumption of drip irrigation is 12% of that of traditional irrigation methods and 50% of that of sprinkler irrigation. The principle of drip irrigation is to supply water through a drip irrigation belt (or drip irrigation pipe) placed at the root of the crop. There are many small water outlets on the drip irrigation belt, and the water overflowing from the outlet slowly moistens the root soil of the crop. Since the moistening range is controllable, drip irrigation is currently the most effective water-saving irrigation method. In addition to saving water, it can also reduce fertilizer loss, promote crop growth, and improve the yield and quality of crops.
[0003] Since the drip irrigation pipes floating on the soil surface or shallowly buried have limited range and depth, the root system of crops will be shallow for a long time, which is not conducive to the growth and lodging resistance of some crops. The existing technology inserts the pointed drip irrigation head into the ground to guide the root system to grow downward longitudinally. However, when the pressure of the drip irrigation head extended into the ground is too high, it causes changes in the soil structure, which is not conducive to irrigation and crop growth. Utility Model Content
[0004] The utility model aims to provide a crop water-saving irrigation device, which is used to solve the problem that when the pressure of the drip irrigation head of the crop water-saving irrigation device extending into the ground is too large, the soil structure changes, which is not conducive to irrigation and crop growth.

[0018] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.
[0019] like Figures 1 to 4 In the embodiment of the crop water-saving irrigation device of the utility model shown, the crop water-saving irrigation device includes a pointed shell 1, a valve head 2 is threadedly connected to the top of the shell 1, a water inlet pipe 3 is provided on the top of the valve head 2, an elastic plate 4 is installed under the water inlet pipe 3, a collection plate 5 is fixedly connected to the inner wall of the valve head 2, a water outlet hole 6 is provided in the center of the collection plate 5, a radial collection groove 7 is provided on the collection plate 5, the elastic plate 4 is in contact with the top of the collection plate 5, and a plurality of water permeable holes 8 are provided on the shell 1.
[0020] Specifically, water flows into the valve head 2 through the water inlet pipe 3. Under the action of water pressure, the elastic plate 4 bends toward the direction of the confluence plate 5. Due to the bending of the elastic plate 4, the confluence groove 7 on the confluence plate 5 is exposed, and the water flows into the confluence groove 7 from the edge of the elastic plate 4, and enters the outer shell 1 from the water outlet hole 6 in the center of the confluence plate 5 and flows out from the water permeable hole 8. The elastic force of the elastic plate 4 resists the water pressure, and the water flow is disturbed and slowed down through the edge of the elastic plate 4 and the confluence groove 7, so as to achieve the purpose of reducing the water flow velocity.
[0021] In one embodiment of the present application, preferably, a water blocking plate 9 is provided at the bottom of the water inlet pipe 3, and a support rod 10 is fixedly connected to the bottom of the water blocking plate 9, and the support rod 10 is fixedly connected to the center of the elastic plate 4, which is used to further disrupt the water flow in the water inlet pipe 3 and reduce the flow velocity, while avoiding the continuous increase in the flow velocity caused by the downward bending deformation of the elastic plate 4.
[0022] In one embodiment of the present application, preferably, a guide rod 11 extending into the water inlet pipe 3 is provided on the upper part of the water blocking plate 9, and the top of the guide rod 11 is a pointed tip to prevent the water blocking plate 9 from shifting during operation. When the elastic plate 4 rebounds, the water blocking plate 9 cannot accurately block the water inlet pipe 3, and the top pointed tip can play a water dividing role so that the water pressure acts on the water blocking plate 9.
[0023] In one embodiment of the present application, preferably, a flexible capsule membrane 12 is provided on the inner wall under the water permeable hole 8, a liquid cavity 13 is provided under the capsule membrane 12, a plurality of hollow floats 14 are provided in the liquid cavity 13, and a penetration hole 15 is provided on the bottom shell of the liquid cavity 13. When the moisture content in the soil continues to increase, the water in the soil enters the liquid cavity 13 through the penetration hole 15. As the amount of water in the liquid cavity 13 increases, the hollow float 14 floats up to prop up the capsule membrane. The propped-up capsule membrane 12 closes the water permeable hole 8 on the shell to prevent the water from continuing to flow into the soil through the water permeable hole 8, thereby avoiding the excessive irrigation water volume affecting plant growth. When the moisture content in the soil decreases, the water in the liquid cavity 13 enters the soil through the penetration hole 15. As the liquid level drops, the float 14 falls, and the capsule membrane 12 resets to expose the water permeable hole 8, and irrigation continues. This is used to avoid excessive irrigation water volume and prevent mud and sand from entering the shell 1. The penetration hole 15 can only allow water to penetrate through when there is an osmotic pressure difference between the inside and the outside.
[0024] In one embodiment of the present application, preferably, a decompression core 16 is provided in the housing 1 above the water permeable hole 8, and a labyrinth flow channel 17 arranged in a circumferential array is provided on the decompression core 16 for slowing down the flow rate of water.
[0025] In one embodiment of the present application, preferably, the top end of the water inlet pipe 3 is provided with anti-slip teeth 18 to prevent it from falling off when connecting the pipeline.
[0026] In summary, in the above-mentioned embodiment of the utility model, the crop water-saving irrigation device, specifically, the water flow at the bottom of the water inlet pipe 3 pushes the water blocking plate 9 downward to squeeze the elastic plate 4, and the elastic plate 4 bends toward the direction of the confluence plate 5. Due to the bending of the elastic plate 4, the confluence groove 7 on the confluence plate 5 is exposed, and the water flows from the edge of the elastic plate 4 into the confluence groove 7, and enters the housing 1 from the water outlet hole 6 in the center of the confluence plate 5. The water flows through the labyrinth flow channel 17 on the decompression core 16 to further slow down the flow rate, and finally flows out from the water permeable hole 8. When the moisture content in the soil continues to increase, the soil The water in the liquid cavity 13 enters the liquid cavity 13 through the penetration hole 15. As the amount of water in the liquid cavity 13 increases, the hollow float 14 floats up and props up the capsule 12. The propped-up capsule 12 closes the water-permeable hole 8 on the shell 1 to prevent the water from continuing to flow into the soil through the water-permeable hole 8, so that the elastic plate 4 is reset when the water pressure above and below the elastic plate 4 is balanced, and the water-blocking plate 9 blocks the water inlet pipe 3; when the moisture content in the soil decreases, the water in the liquid cavity 13 enters the soil through the penetration hole 15. As the liquid level drops, the float 14 falls, and the capsule 12 is reset to expose the water-permeable hole 8, so that irrigation can continue. The water flow speed is slowed down by the elastic plate 1 and the labyrinth flow channel 17 to meet the drip irrigation requirements, and the capsule 12 closes or opens the water-permeable hole 8 by the change of the soil moisture content, so as to control the irrigation amount and prevent mud and sand from entering the drip irrigation head when no irrigation is performed.
