Description

Technical Field

[0001] This utility model relates to the field of water conservancy and irrigation technology, and in particular to a farmland water conservancy and irrigation device. Background Technology

[0002] Mountains cover more than 65% of my country's land area. The mountainous terrain is complex, and agricultural production mainly takes place on ridges, slopes, and terraces. To this day, mountain agriculture still relies heavily on rainfall and often experiences drought. However, crops need timely and appropriate water to ensure their yield. Therefore, when rainfall is insufficient or unevenly distributed and cannot meet the water requirements of crops, irrigation is necessary to supplement the lack of natural rainfall.

[0003] Irrigation devices are used during irrigation, such as the farmland irrigation device with prior art authorization publication number CN213784574 U. This device has a rotating shaft block fixedly connected to the outer surface of a connecting plate. An adjusting rod is movably connected to one side of the rotating shaft block, and a support rod is slidably connected to the other side of the adjusting rod. Several adjusting holes are arranged in a parallel array on one side of the adjusting rod, and a regulator is threaded onto one side of the support rod. This farmland irrigation device uses four support rods to stably fix the connecting plate to the ground, the adjusting holes and regulator to fix the support rod and adjusting rod, a side pipe for spraying water to increase the irrigation area, a pressure plate to spray water in a disc shape, a hose to connect to a water delivery pipe to deliver water to the spray pipe, and a filter screen to filter large particles and prevent clogging of the spray pipe.

[0004] However, after the irrigation device is used up and the water supply is stopped, the impurities at the bottom of the filter screen will flow back into the water supply pipe with the water flow, making it inconvenient for staff to clean the impurities inside the pipe later.

[0005] Therefore, it is necessary to provide a farmland irrigation device to solve the above-mentioned technical problems. Utility Model Content

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] First Embodiment Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a farmland irrigation device provided by this utility model; Figure 2 for Figure 1 The diagram shows a partial cross-sectional structure. Figure 3 for Figure 2 The enlarged schematic diagram of part A shown below; Figure 4 for Figure 3 The diagram shows a filter frame structure. A farmland irrigation device includes: a rigid pipe 1; The filter tube 2 is threaded to the top of the rigid tube 1. Connecting tubes 21 are fixedly installed on the bottom of both sides of the filter tube 2. The output ends of the two connecting tubes 21 are fixedly installed on the top of both sides of the filter tube 2. A guide plate 22 is fixedly installed on the inner side of the filter tube 2. A one-way valve 23 is fixedly installed at the bottom of the guide plate 22. The spraying assembly 3 is threadedly connected to the top of the filter tube 2. Both ends of the bottom of the spraying assembly 3 are fixedly installed with connecting rods 31. A filter plate 32 is fixedly installed at the bottom of the connecting rods 31. A partition plate 33 is fixedly installed at the bottom of the filter plate 32. A filter frame 34 is fixedly installed at the bottom of the partition plate 33.

[0018] By setting a partition 33 between the output ends of the two connecting pipes 21, it can not only connect the filter plate 32 and the filter frame 34 during use, but also prevent the output ends of the two connecting pipes 21 from colliding. The filter frame 34 is made of metal bracket and has a filter screen on its outer side, which can filter impurities during use. The spraying assembly 3 is equipped with multiple spray pipes. When in use, water can be sprayed from multiple spray pipes, thereby increasing the spraying range.

[0019] A support assembly 4 is fixedly installed on the outer side of the rigid tube 1.

[0020] Support component 4 is an adjustable support bracket that supports the spraying component 3 during use.

[0021] A flexible tube 5 is fixedly installed at the bottom of the rigid tube 1, and a main pipe 6 is fixedly installed at the bottom of the flexible tube 5.

[0022] When in use, the main pipe 6 is connected to a water pump, which then delivers water into the main pipe 6.

[0023] The outer surfaces of the filter plate 32 and the filter frame 34 are both attached to the inner surface of the rigid tube 1, and the bottom of the filter frame 34 is located at the top of the guide plate 22.

[0024] The input end of the connecting pipe 21 is located at the bottom of the guide plate 22, and the output end of the connecting pipe 21 is located at the bottom of the filter plate 32.

[0025] The working principle of the farmland irrigation device provided by this utility model is as follows: When in use, the rigid pipe 1 is supported in the farmland by the support component 4. Then, the water enters the inside of the flexible hose 5 through the main pipe 6, and then enters the inside of the filter pipe 2 through the flexible hose 5 and the rigid pipe 1. The water entering the filter pipe 2 will be split through two connecting pipes 21 and directly enter the bottom of the filter plate 32. The filter plate 32 filters the water and removes impurities from the water. The filtered water is then evenly sprayed into the farmland through the spray component 3 to irrigate the crops. When the main pipe 6 stops supplying water, the water inside the filter pipe 2 will flow downwards along the filter pipe 2. At this time, the filter frame 34 plays a secondary filtration role, which allows impurities to accumulate inside the filter frame 34, while the remaining relatively clean water will flow back into the main pipe 6 through the one-way valve 23. Then, the user can rotate the spray assembly 3 to remove the spray assembly 3 from the top of the filter pipe 2. Since the connecting rod 31 at the bottom of the spray assembly 3 is connected to the filter plate 32, and the bottom of the filter plate 32 is connected to the partition plate 33 and the filter frame 34 in sequence, the filter plate 32 and the filter frame 34 inside the filter pipe 2 can be brought out together through the connecting rod 31 and the partition plate 33. Then, the user can clean the impurities on the inner side of the filter frame 34, which is convenient and quick.

[0026] Compared with related technologies, the farmland irrigation device provided by this utility model has the following beneficial effects: The components, including rigid pipe 1, filter pipe 2, connecting pipe 21, guide plate 22, one-way valve 23, spray assembly 3, connecting rod 31, filter plate 32, baffle 33, and filter frame 34, work together to trap impurities in the filter frame 34 when the main pipeline 6 stops supplying water. This prevents impurities from flowing back into the main pipeline 6 with the water flow, making it easier for staff to clean the impurities in the filter frame 34.

[0027] Second Embodiment Please refer to the following: Figure 5 and Figure 6 Based on the farmland irrigation device provided in the first embodiment of this application, the second embodiment of this application proposes another farmland irrigation device. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0028] Specifically, the difference in the second embodiment of this application regarding the farmland irrigation device is that, in the farmland irrigation device, both sides of the inner side of the rigid pipe 1 are provided with mounting grooves 7, and the inner side of the mounting grooves 7 is rotatably connected to a baffle plate 71.

[0029] The baffle plate 71 is disposed at the output end of the connecting pipe 21.

[0030] The working principle of the farmland irrigation device provided by this utility model is as follows: When the main pipe 6 stops supplying water, there is no water flow inside the connecting pipe 21, so the baffle plate 71 cannot be pushed open. At this time, the baffle plate 71 will rotate, so that one side of the baffle plate 71 abuts against the output end of the connecting pipe 21. At this time, the water inside the filter pipe 2 cannot flow back through the connecting pipe 21, but can only flow back to the inside of the main pipe 6 through the one-way valve 23.

[0031] Compared with related technologies, the farmland irrigation device provided by this utility model has the following beneficial effects: By installing a groove 7 and a baffle plate 71 at the output end of the connecting pipe 21, when the water supply is stopped, the water and impurities inside the filter pipe 21 can be prevented from flowing back into the main pipe 6 through the connecting pipe 21, thereby increasing the filtration effect on impurities.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
