Description
Technical Field
[0001] The utility model belongs to the technical field of agricultural irrigation, in particular to an agricultural water-saving irrigation pipeline. Background Art
[0002] Agricultural water-saving irrigation not only helps to ensure national food security, but also has a positive impact on the economy, society, ecology and other aspects. By implementing effective water-saving measures and technologies, we can reduce the pressure on water resources and promote sustainable development while ensuring agricultural production. Existing irrigation pipes are equipped with sprinklers, which are easily blocked by the external environment such as soil or other impurities in the field when not in use. Utility Model Content
[0003] The purpose of the utility model is to provide an agricultural water-saving irrigation pipeline to avoid clogging of the nozzle in view of the above-mentioned technical problems.
[0004] In view of this, the utility model provides an agricultural water-saving irrigation pipeline, including a flow pipeline, the flow pipeline is connected to a spraying unit, the spraying unit includes a shell and a liquid outlet head slidably arranged in the shell, the liquid outlet head is provided with a liquid outlet hole, and the liquid outlet head is connected to an elastic part, wherein in a non-irrigation state, the liquid outlet hole is blocked by the shell.
[0005] In the present technical solution, water in the flow pipe enters the shell of the spray unit. When irrigation is needed, the internal water pressure increases, and the water flow pushes the liquid outlet head slidingly arranged in the shell to extend out of the shell to complete irrigation. When irrigation is stopped, the water flow in the flow pipe decreases, the water pressure drops, and the elastic part drives the liquid outlet head to retract into the shell to complete reset, thereby preventing the liquid outlet hole on the liquid outlet head from being exposed to the outside, and the soil or other impurities in the field may easily cause blockage of the liquid outlet hole.
[0006] In the above technical solution, further, the shell includes a mounting portion connected to the flow pipe and a flow portion in which a liquid outlet head is slidably provided.
[0007] In the above technical solution, further, the flow portion is provided with a liquid inlet connected to the flow pipeline, a liquid outlet is provided on the other side of the flow portion, and a liquid outlet head is provided to seal the liquid outlet.
[0008] In this technical solution, the flow part is a hollow cylindrical structure with a liquid inlet on one side connected to the flow pipe and a liquid outlet on the other side connected to the outside. The liquid outlet is sealed with a liquid outlet head, which can ensure that the liquid outlet head extends out of the liquid outlet under the push of water flow to complete irrigation.
[0009] In the above technical solution, further, the liquid outlet head includes a main body, a liquid outlet hole is provided at one end of the liquid outlet of the flow part of the main body, an opening is provided at the other end of the main body, a first flange is provided at the opening and abuts against the side wall, and the first flange is connected to the second flange provided at the liquid inlet of the flow part through an elastic member.
[0010] In the present technical solution, the elastic member is a spring, and its two ends are fixedly connected to the first flange and the second flange respectively. During irrigation, the internal pressure of the flow pipe is increased, and the water flow pushes the liquid outlet head to move outward along the flow part. The elastic member is stretched, and the liquid outlet head extends out of the shell. The liquid outlet hole on the liquid outlet head is not blocked, and water flows out from the liquid outlet hole for irrigation. After the irrigation is completed, the water flow in the flow pipe decreases, and the water pressure decreases. Under the elastic reset action of the elastic member, the liquid outlet head is driven to reset, and the liquid outlet hole on the liquid outlet head is blocked again to avoid being exposed to the outside. The soil or other impurities in the field can easily cause blockage of the liquid outlet hole.
[0011] In the above technical solution, further, an annular support plate is provided on one side of the liquid outlet of the flow part, a vertical plate is provided on the support plate corresponding to the liquid outlet hole of the liquid outlet head, and a conical protrusion is provided on the vertical plate facing the liquid outlet hole.
[0012] In the technical solution, after the water jetted from the liquid outlet hits the conical protrusion, the water will splash and spray small droplets around, which is significantly helpful for water saving and sufficient irrigation.
[0013] In the above technical solution, further, a sleeve is formed on the outer wall of the flow pipe, a flow port is provided between the sleeve and the outer wall of the flow pipe, and the sleeve is threadedly connected to the mounting portion of the spray unit.
[0014] In the present technical solution, a sleeve is provided on the outer wall of the flow conduit, and the sleeve and the mounting portion of the spray unit are threadedly connected, so as to achieve fast and reliable installation. The mounting portion of the spray unit is a circular plate structure with internal threads.
[0015] In the above technical solution, further, an extension portion is provided between the mounting portion and the flow portion in the shell and extends outward, and a filter screen is provided in the extension portion.
[0016] In the present technical solution, the filter screen is used to intercept impurities in the irrigation water, and the impurities will be retained in the extended portion extending outward, making it convenient for operators to remove the shell to clean the impurities.
[0017] The beneficial effects of the utility model are:
[0018] 1. During irrigation, the flow pipe is pressurized, the water flow pushes the liquid outlet head to move outward along the flow part, the elastic member is stretched, the liquid outlet head extends out of the shell, the liquid outlet hole on the liquid outlet head is not blocked, and water flows out from the liquid outlet hole for irrigation. After irrigation is completed, the water flow in the flow pipe decreases, the water pressure decreases, and the elastic resetting action of the elastic member drives the liquid outlet head to reset, and the liquid outlet hole on the liquid outlet head is blocked again to avoid being exposed to the outside. Soil or other impurities in the field can easily block the liquid outlet hole;
[0019] 2. An annular support plate is provided on one side of the liquid outlet of the flow part, and a vertical plate is provided on the support plate corresponding to the liquid outlet hole of the liquid outlet head, and a conical convex block is provided on the side of the vertical plate facing the liquid outlet hole. When the water jetted from the liquid outlet hits the conical convex block, the water will splash and spray small droplets around, which is significantly helpful for water saving and sufficient irrigation;
