Pipeline dredging device for garden irrigation

The utility model discloses a pipeline dredging device for garden irrigation. Including a base, two sleeves are fixedly connected to two sides of the top end of the base; two sliding blocks are respectively connected in the two sleeves in a sliding manner; two springs are respectively arranged in the two sleeves; the top of the spring is fixedly connected with the slider bottom; according to the device, the two U-shaped water pipes are alternately opened; impurities are discharged through impact force of water flow. When the U-shaped water pipe is blocked; the whole device vibrates through thevibrator; the impurities slide off in a continuous shaking state; therefore, the device is helped to discharge impurities; the labor intensity of workers is greatly reduced, cleaning can be completedwithout stopping the device, the working efficiency is indirectly improved, the filter screens can be circularly and alternately used and replaced by rotating the threaded rod, the replacement periodof the filter screens is g
