Brake shoe support detection device for agricultural machinery

The utility model is applicable to the technical field of brake shoes, and provides a brake shoe support detection device for agricultural machinery, which comprises an outer ring, a fixed disc, support columns, a swing assembly and a detection assembly, the support columns are rotatably mounted on the surface of the fixed disc, and a brake shoe I and a brake shoe II are fixedly mounted on the support columns at different positions; the swing assembly is installed on the fixed disc and is driven by an external motor to rotate. The detection assembly is arranged in an inner cavity of the fixed disc, and one end of the detection assembly is connected with the execution end of the swing assembly; when the detection device is used, due to the fact that the supporting column is movable and is matched with the detection assembly arranged in the inner cavity of the fixing disc, multidirectional detection of the supporting column can be achieved, detection dead angles are not left, and therefore the obtained result i
