[0002] In agricultural production, integrated water-fertilizer irrigation technology has been widely used. In some large-scale vegetable planting bases, the integrated water-fertilizer irrigation system is used, which can automatically adjust the ratio of fertilizer and water according to the fertilizer requirements and soil moisture conditions of different vegetable varieties, and realize precise irrigation and fertilization.

[0003] However, irrigation water often contains impurities, suspended matter and harmful substances. If it is not effectively filtered, it will not only affect the irrigation effect, but may also clog the irrigation pipes and nozzles, reducing the service life of the equipment.

However, when cleaning the filters, it may be inconvenient to clean the impurities in the filter holes on the filters without disassembling the filters, which may cause some impurities to remain in the filter holes, thereby greatly reducing the efficiency of water filtration.

Two baffle plates 52 are arranged in each water collecting cylinder 2, and the shaft rod 55 movably penetrates one of the baffle plates 52. The three filter cylinders 51 filter the water in turn to separate the granular impurities of different sizes in the water. The shaft rod 55 drives the cross plate 56 to rotate, so that the filter cylinder 51 rotates accordingly. After water is flushed into the inside of the cleaning pipe 53, it is discharged through the water spray hole 54.

Two connecting pipes 7 are provided to facilitate the transfer of filtered water from two adjacent water collecting cylinders 2 from top to bottom.

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, the driving assembly 3 includes a motor 31 fixed on the steel frame 1, a large transmission wheel 32 fixed on the output end of the motor 31, a small transmission wheel 33 transmission-connected to the large transmission wheel 32, and a belt 34 transmission-connected to the small transmission wheel 33. The shaft rod 55 located inside the middle water collecting cylinder 2 is fixedly connected to the large transmission wheel 32. After the motor 31 is running, the shaft rods 55 inside the three water collecting cylinders 2 are rotated simultaneously through the large transmission wheel 32, the small transmission wheel 33 and the belt 34, so that the impurities on the filter cylinder 51 are cleaned simultaneously.

[0030] like Figure 1 As shown, the irrigation assembly 4 includes a mixing drum 41 below the steel frame 1, an irrigation pump 43 fixed on the mixing drum 41, and a water inlet pipe 42 fixed on the top of the mixing drum 41.

[0031] A water-fertilizer integrated irrigation device adopts the above-mentioned filtering structure.

[0032] Working principle: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, when using this filtering structure and water-fertilizer integrated irrigation device, firstly, tap water is introduced into the water collecting cylinder 2 located at a high position, and the tap water seeps out from the inside to the outside through the filter cylinder 51, and the impurities in the water are separated, and then filtered in sequence through three filter cylinders 51, and the two adjacent filter cylinders 51 are connected through the flushing pipe 6 and the connecting pipe 7. After the filtering of the filter cylinder 51 located at the lowest position is completed, the water is transmitted to the inside of the mixing cylinder 41 through the water inlet pipe 42, and then transferred through the irrigation pump 43 to irrigate the crops; The motor 31 runs, and through the cooperation of the large transmission wheel 32, the small transmission wheel 33 and the belt 34, the shafts 55 in the three water collecting cylinders 2 rotate accordingly, and the shafts 55 drive the cross plate 56 to rotate, and the filter cylinder 51 rotates accordingly. The water supply pipe 57 on the highest water collecting cylinder 2 is connected to the clean water through a water pump. The clean water is transmitted to the inside of the cleaning pipe 53 through the water storage box 513 and sprayed out through the water spray hole 54 to wash the filter holes on the baffle 52 to prevent impurities from clogging the inside of the filter holes, thereby backwashing the filter cylinder 51. During the rotation of the filter cartridge 51, the inner wall of the filter cartridge 51 rubs against the scraper 58 to remove impurities attached to the inner wall of the filter cartridge 51. Subsequently, the cleaned liquid and impurities inside the filter cartridge 51 are transmitted to the inside of the discharge pipe 511 through the drain pipe 510. The third solenoid valve 512 facilitates the outflow of the liquid inside the discharge pipe 511. While removing impurities, the first solenoid valve 44 and the second solenoid valve 46 operate, so that the impurities flowing into the water inlet pipe 42 are transmitted to the inside of the discharge pipe 511 through the diversion pipe 45, thereby facilitating the centralized discharge of impurities.
