Description

Technical Field

[0001] This utility model relates to the field of farmland irrigation technology, specifically a farmland water conservancy water-saving pipe. Background Technology

[0002] Irrigation pipes, also known as irrigation pipes, are often made of PVC resin powder as the main raw material, with the addition of appropriate additives. They are processed and shaped through processes such as mixing, extrusion, sizing, cutting, and flaring. In order to irrigate a large area of ​​farmland, many holes are often made in the irrigation pipe so that the water entering the irrigation pipe can be sprayed out from the holes to irrigate the farmland.

[0003] As disclosed in the application document with application number 202323048400.3, a water-saving irrigation pipe for farmland is proposed. This utility model, through the combined use of a steering component, a welding frame, and a sprinkler pipe, allows the sprinkler pipe to adjust its spraying area when irrigating farmland. On the one hand, this allows the sprinkler pipe to water the farmland more evenly, and on the other hand, it allows the sprinkler pipe to be adjusted during use to prevent spraying outside the farmland, thereby reducing water waste. However, this water-saving irrigation pipe can only provide directional irrigation for crops in one direction. Multiple corresponding irrigation holes still need to be opened on one pipe to spray and irrigate crops planted in the same row. However, with high crop planting density and multiple rows planted at one time, multiple sets of equipment are needed to spray and irrigate simultaneously using the corresponding irrigation holes. This still requires a large water supply, making it difficult to cover all crops with the same amount of irrigation water, and therefore it is not conducive to water-saving use.

[0004] Therefore, in view of this, we studied and improved the existing structure to propose a water-saving pipeline for farmland irrigation. Utility Model Content

[0005] The purpose of this utility model is to provide a water-saving pipeline for farmland irrigation to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water-saving irrigation pipe for farmland, comprising a water supply pipe, a secondary pipe fixedly connected to the upper surface of the water supply pipe, a conveying pipe rotatably mounted on the upper side of the inner surface of the secondary pipe using a sealed bearing, a water wheel inside the secondary pipe, a connecting rod fixedly mounted in the middle of the upper surface of the water wheel, the upper end of the connecting rod being fixedly connected to the top of the inner surface of the conveying pipe, flexible hoses fixedly connected to both sides of the outer surface of the conveying pipe, a nozzle fixedly connected to the end of the flexible hose away from the conveying pipe, and the same adjustment mechanism being provided on the outer side of the secondary pipe and the lower surface of the nozzle.

[0007] Preferably, a top cover is fixedly installed on the top of the outer surface of the conveying pipe, a fixing frame is fixedly installed on the upper side of the outer surface of the conveying pipe, and the nozzles on both the left and right sides are rotatably connected inside the fixing frame.

[0008] Preferably, the adjustment mechanism includes an assembly ring sleeved on the outer side of the secondary tube, and the upper surface of the assembly ring has a groove circumferentially formed.

[0009] Preferably, the adjustment mechanism further includes annular grooves corresponding to the front and rear sides of the inner surface of the groove, and the annular grooves are arranged in an up-and-down wave pattern. Two adjustment rods are symmetrically arranged inside the groove, and the upper ends of the adjustment rods are rotatably connected to the nozzle.

[0010] Preferably, the adjustment mechanism further includes movable rods that are rotatably mounted on both the left and right sides of the bottom end of the adjustment rod. The movable rods are slidably located inside the annular groove, and the movable rods and the adjustment rods combine to form an inverted "T" shape.

[0011] Preferably, connecting blocks are fixedly installed on both the left and right sides of the outer surface of the secondary tube, and the connecting blocks are fixedly connected to the assembly ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the setting of conveying pipe, water wheel, connecting rod, hose and nozzle, only requires a single nozzle structure to fully irrigate the crops from all 360 degrees around them, without the need to pull multiple pipes for irrigation, thus greatly saving water resources, avoiding waste, and making fuller use of water resources. In addition, the elevated design of the conveying pipe can also avoid irrigation blockage.

[0014] 2. This utility model, through the setting of adjustment mechanism, assembly ring, groove, ring groove, adjustment rod and movable rod, can adjust the up and down angle of the nozzle, thereby continuously adjusting the spraying and irrigation position, thereby further expanding the spraying coverage area, avoiding the situation where the nozzle rotates at a fixed angle and can only form a fixed range of circular spraying and irrigation, so as to make irrigation more comprehensive, the irrigation coverage area wider, and the amount of crops irrigated by the same nozzle structure, thus saving more water resources;

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-3 As shown, a water-saving irrigation pipeline for farmland includes a water supply pipe 1, a secondary pipe 2 fixedly connected to the upper surface of the water supply pipe 1, a conveying pipe 3 rotatably mounted on the upper side of the inner surface of the secondary pipe 2 using a sealed bearing, a water wheel 4 inside the secondary pipe 2, a connecting rod 5 fixedly mounted in the middle of the upper surface of the water wheel 4, the upper end of the connecting rod 5 fixedly connected to the top of the inner surface of the conveying pipe 3, flexible hoses 6 fixedly connected to both sides of the outer surface of the conveying pipe 3, a nozzle 7 fixedly connected to the end of the flexible hose 6 away from the conveying pipe 3, and the same adjusting mechanism 11 provided on the outer side of the secondary pipe 2 and the lower surface of the nozzle 7; multiple secondary pipes 2 and structural devices installed on the upper side of the secondary pipes 2 can be added at equal intervals according to the length of the same water supply pipe 1.

[0022] By adopting the above technical solution, irrigation water is transported into the delivery pipe 3 through the secondary pipe 2, and then continues to flow into the hose 6 using water pressure to supply water to the sprinkler head 7. The irrigation water is then sprayed by the sprinkler head 7 for agricultural irrigation.

[0023] The flow of water will drive the water wheel 4 to rotate, and the water wheel 4 will drive the entire delivery pipe 3 to rotate through the connecting rod 5, so that the sprinkler head 7 can rotate to irrigate.

[0024] The design of the delivery pipe with 3 high-nozzle units 7 can prevent irrigation blockages.

[0025] Furthermore, a top cover 8 is fixedly installed on the top of the outer surface of the conveying pipe 3, and a fixing frame 9 is fixedly installed on the upper side of the outer surface of the conveying pipe 3, and the nozzles 7 on both the left and right sides are rotatably connected inside the fixing frame 9.

[0026] By adopting the above technical solution, flags or strips of cloth can be installed on the upper end of the top cover 8. When the conveying pipe 3 rotates, the top cover 8 can also rotate, thereby causing the flags and strips of cloth to rotate and flutter, which can have the effect of repelling birds and preventing birds from eating crops.

[0027] Furthermore, the adjustment mechanism 11 includes an assembly ring 1101 sleeved on the outer side of the secondary pipe 2, and a groove 1102 is circumferentially formed on the upper surface of the assembly ring 1101; the adjustment mechanism 11 also includes annular grooves 1103 correspondingly formed on the front and rear sides of the inner surface of the groove 1102, and the annular grooves 1103 are arranged in a wave-like manner; two adjustment rods 1104 are symmetrically arranged on the left and right sides inside the groove 1102, and the upper end of the adjustment rods 1104 is rotatably connected to the nozzle 7; the adjustment mechanism 11 also includes movable rods 1105 rotatably installed on both the left and right sides of the bottom end of the adjustment rods 1104, the movable rods 1105 are slidably located inside the annular grooves 1103, and the movable rods 1105 and the adjustment rods 1104 combine to form an inverted "T" shape.

[0028] By adopting the above technical solution, when the nozzle 7 is rotated and adjusted, it will drive the adjusting rod 1104 to move synchronously around in the groove 1102.

[0029] When the adjusting rod 1104 moves around, the movable rod 1105 will move along with it and be restricted by the annular groove 1103. The wave-shaped annular groove 1103 will push the movable rod 1105 up and down, so that the adjusting rod 1104 pushes the nozzle 7 to adjust the up and down angle while rotating, continuously adjusting the spraying and irrigation position, thereby further expanding the spraying coverage area.

[0030] The movable rod 1105 can rotate, which can create rolling friction between the movable rod 1105 and the annular groove 1103. This can significantly reduce the wear caused by friction during movement and extend the service life of the device.

[0031] The movable rod 1105 and the adjusting rod 1104 combine to form an inverted "T" shape, which ensures the stability of the adjusting rod 1104 and prevents it from shaking and dislodging from the groove 1102.

[0032] Furthermore, connecting blocks 10 are fixedly installed on both the left and right sides of the outer surface of the secondary tube 2, and the connecting blocks 10 are fixedly connected to the assembly ring 1101.

[0033] By adopting the above technical solution, the connecting block 10 fixes the assembly ring 1101, that is, the bottom base point of the entire adjustment mechanism 11.

[0034] Working principle: When using this farmland water conservancy water-saving pipeline, firstly, the entire water supply pipe 1 is laid in the middle of the farmland, flexibly determined according to the farmland area. Then, irrigation water is delivered into the water supply pipe 1. The irrigation water is delivered into the delivery pipe 3 through the secondary pipe 2, and continues to flow into the hose 6 using water pressure to supply water to the sprinkler heads 7. The irrigation water is sprayed by the sprinkler heads 7 for agricultural irrigation. When the irrigation water enters the secondary pipe 2, the water flow force will drive the water wheel 4 to rotate. The water wheel 4 drives the entire delivery pipe 3 to rotate through the connecting rod 5, which allows the sprinkler heads 7 to rotate and irrigate. In a block of land, only one sprinkler head 7 structure is needed to irrigate the crops in a 360-degree radius. During adjustment, the adjusting rod 1104 moves synchronously around the groove 1102. As the adjusting rod 1104 moves around, the movable rod 1105 moves along with it and is restricted by the annular groove 1103. The wave-shaped annular groove 1103 pushes the movable rod 1105 up and down, so that the adjusting rod 1104 pushes the nozzle 7 to rotate while adjusting the up and down angle, thereby continuously adjusting the spraying and irrigation position, and further expanding the spraying coverage. This avoids the situation where the nozzle 7 rotates at a fixed angle and can only form a fixed range of circular spraying and irrigation, making irrigation more comprehensive and the irrigation coverage wider. This is the working principle of this farmland water conservancy water-saving pipeline.
