The invention discloses a fixed-point shutdown device for a circular electric sprinkling irrigation machine. The fixed-point shutdown device comprises a sprinkling irrigation pipeline, tires, a sprinkling irrigation machine electric con trol cabinet and a fold-back control unit which is used for achieving fixed-point limiting and the automatic fold-back function. The fold-back control unit comprises a positioning assembly, a fold-back assembly and a fixed-point control assembly. The positioning assembly is a fixed-point limiting pile. The fold-back assembly is composed of a cross beam, a left touch rod, a right touch rod, a left pull rod and a right pull rod. The fixed-point control assembly is composed of a box body, a left fold-back assembly body and a right fold-back assembly body, wherein the left fold-back assembly body and the right fold-back assembly body are mounted in the box body. Each fold-back assembly body is composed of a rotary shaft, a ratchet wheel and a microswitch. By means of the technical scheme, the fixed-point shutdown device overcomes the defects in the prior art, is simple in structure, capable of saving time and labor and achieving fixed-point shutdown and automatic fold-back and flexible and convenient to operate, water resources are saved, the sprinkling irrigation efficiency is improved, and cost is lowered.
