[0002] As an important product in the field of farmland irrigation, the anti-scouring trough is widely used in farmland water diversion, crop irrigation, farmland fertilization and other purposes due to its characteristics of easy installation, high water discharge efficiency, long service life and low maintenance cost. Its working principle is mainly to introduce water into the anti-scouring trough box through the water inlet at the bottom, and then through the water outlet on the side of the anti-scouring trough and the guide plate connected to the water outlet to realize the water diversion and irrigation of the farmland.

[0003] At present, most of the existing anti-scouring trough bodies adopt a water outlet structure, and a sealing cover is set outside the water outlet. It needs to be assembled on site when in use, which is not convenient, and the sealing is not good and water is easy to leak. For example, patent application number "201420296216.2" introduces a farmland irrigation water outlet, including an inlet pipe, an outlet pipe, a screw, and a knob. The water volume is controlled by a water blocking sheet and a screw, and the inlet pipe and the outlet pipe of the outlet are connected by a flange. However, its structure is complex and inconvenient to adjust. It is suitable for small flow irrigation control, and lacks an external sealing cover. For example, patent application number "201920049512.5" discloses a pull-up water outlet, including an upper cover outlet pipe, an inlet valve seat and a lower riser. It adopts a pull-up structure, which requires manual operation, and the water outlet does not have an anti-scouring function, which is easy to form an impact fracture surface at the water inlet of the farmland. For this reason, the existing farmland irrigation anti-scouring trough structure needs to be further improved. Utility Model Content
