[0003] When detecting the slump of the concrete, in order to avoid interference with the concrete cone during lifting the slump cone, it is necessary to ensure the verticality of the upward movement of the slump cone and avoid deflection of the slump cone. However, most of the current slump cones only have two handles fixed on the outside of the cylinder, and the slump cone is manually lifted upward by holding the handles. This operation is difficult and has a high failure rate. Moreover, after completing the slump detection of the concrete, the collapsed concrete is not easy to clean from the detector, and the slump detection of the next batch of concrete cannot be quickly performed, which reduces the efficiency of the concrete slump detection.
