Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural irrigation, in particular to a water-saving device for farmland irrigation. Background Art

[0002] Farmland irrigation refers to the process of delivering water to farmland in various ways in order to meet the water needs of crop growth and development. It is a key link in agricultural production and has a very important impact on the yield and quality of crops. There are many ways to irrigate farmland, including traditional ground irrigation, such as flooding and furrow irrigation, etc.; there are also more water-saving and efficient sprinkler irrigation and drip irrigation. The operation of ground irrigation is relatively simple, but its water resource utilization rate is relatively low. Sprinkler irrigation can evenly spray water on farmland and is suitable for large areas of farmland. Drip irrigation can accurately deliver water directly to the roots of crops, greatly improving the utilization efficiency of water resources. The timing and amount of farmland irrigation need to be comprehensively judged and accurately grasped based on a variety of factors such as crop type, growth stage, soil moisture and climatic conditions;

[0003] The Chinese patent with the announcement number "CN218353778U" discloses a novel water-saving device for farmland irrigation, including a valve body, a constraint ring, a valve stem, a turning handle, a valve plate, a fixing plate, a screw, a rotating disk, a water pipe, a rotating joint and a nozzle. The valve body is connected to a water supply device, the constraint ring is installed on the top of the valve body, the valve stem is rotatably installed at the bottom of the valve body and is rotatably connected to the constraint ring, the turning handle is installed on the top of the valve stem, the valve plate is installed on the valve stem and is located inside the valve body, the fixing plate is installed on the top of the valve body, the screw is threadedly connected to the fixing plate and corresponds to the position of the valve stem, the rotating disk is installed at the front end of the screw, the water pipe input end is connected to the valve body, and the nozzle is rotatably connected to the water pipe output end through a rotating joint. By setting up this device, water can be sprayed out through the nozzle in a rotating manner, thereby expanding its irrigation range, thereby saving water for farmland irrigation;

[0004] During the specific application of the above-mentioned device, although the overall device can play a good irrigation role, during its specific application, the interior of the overall pipeline lacks a corresponding filtering structure. During use, when the irrigation water is supplied, impurities and dust are very likely to exist in the water. The impurities and dust flow and accumulate in the pipeline for a long time, which can easily cause blockage in the water-saving valve or the nozzle and the pipeline. In the prior art, although additional filters are used to prevent blockage, during the application of the filters, dust is very easy to adhere to the outer surface of the filters, thereby reducing its water permeability, thereby affecting the filtration efficiency of the water in the entire device, and reducing the circulation efficiency of the water. It can be seen that the prior art has certain defects and deficiencies, and therefore needs to be improved. Utility Model Content

The water flow drives the turbine to rotate, driving the semi-toothed ring to rotate. The semi-toothed ring engages with the rack, driving the slider to slide and displace in the movable rail frame. The semi-toothed ring intermittently drives with the two sets of racks, causing it to reciprocate horizontally left and right in the outer frame, thereby driving the slider to reciprocate. At this time, the brush plate rotates and displaces horizontally under the drive of the turbine, which can automatically reciprocate and clean the filter screen to avoid blockage, thereby improving the protective filtering ability.

[0031] Principle and advantages of use: By setting the filter mechanism 6, during use of the device, water can be assisted in water supply through the delivery pipe 1, and water enters the interior of the filter box 2, and the dust is assisted in filtering and screening through the filter screen 62 inside the filter box 2. Since the filter screen 62 is arranged obliquely, the filtering surface of the filter screen 62 is located at the top inclined surface, and the filtered dust can fall downward naturally. After the dust falls, it can enter the collecting bucket 8 at the bottom of the filter box 2, and the collecting bucket 8 assists in guiding and collecting. If auxiliary cleaning is required, the bottom of the collecting bucket 8 can be opened by twisting the sealing screw cover 9, so that dust and impurities can be quickly and conveniently removed. At the same time, when the filter screen 62 needs to be inspected and maintained, the limiting screw 11 can be loosened, and the end of the limiting screw 11 is separated from the limiting hole 12. At this time, the sealing cover 3 on the top of the filter box 2 can be removed, so that the filter mechanism 6 can be disassembled and assembled, so that the overall device is convenient for inspection and maintenance, which can improve the convenience of overall inspection and maintenance of the device.

[0032] By setting the filtering mechanism 6, when the device is in use, when the filter screen 62 assists in filtering dust and impurities, most of the filtered dust and impurities will automatically fall into the interior of the collecting bucket 8. When a small amount of dust adheres to the outer surface of the filter screen 62, it can be removed by the cleaning brush plate 635. The flow of water can drive the turbine 644 to rotate, and the rotation of the turbine 644 drives the semi-toothed ring 642 to rotate. The semi-toothed ring 642 and the rack 643 are engaged. As the semi-toothed ring 642 rotates, the slider 633 can be driven to slide inside the movable rail frame 632, and the semi-toothed ring 642 moves to the outer frame. When the brush plate is driven by the turbine 644 to rotate, it can also move laterally, and can automatically and reciprocately clean the filter screen 62 inside the filter box 2, so as to avoid the filter screen 62 from being blocked, thereby improving the overall protection and filtering ability of the device.
