Agricultural non-point source pollution control device

The invention relates to the technical field of non-point source pollution control, in particular to an agricultural non-point source pollution control device. Comprising an intercepting plate; the intercepting plate is a plate-shaped object with filtering holes; an edge frame; the edge frame is fixedly connected to the edge of the intercepting plate and wraps the position, making contact with the ditch, of the intercepting plate. The edge frame can be inserted into the ditch through the insertion rod to realize positioning; a main sleeve; the main sleeve is fixedly connected to the upper part of the intercepting plate; a main shaft; the main shaft is rotationally connected into the main sleeve; two ends of the main shaft extend out of the main sleeve; a fan blade; the fan blades are located on the side, opposite to the coming direction of water flow, of the intercepting plate. According to the cleaning device, the rotating fan blades drive the fishing plate to fish out solid waste in the ditch, and the solid
