Concrete slump detection device

The utility model relates to a concrete slump detection device which comprises a slump cone, a material guide cylinder and a pedal, the slump cone and the material guide cylinder are both frustoconical cylinders, the pedal is fixedly connected to the lower end of the outer side wall of the slump cone, and a supporting mechanism is arranged on the slump cone. The supporting mechanism comprises a supporting ring coaxially and fixedly connected to the upper end of the outer side wall of the slump cone, a supporting barrel is coaxially and fixedly connected to the outer side wall of the material guiding barrel, the end, with the minimum diameter, of the material guiding barrel is located in the supporting barrel, and when the end, with the minimum outer diameter, of the material guiding barrel is coaxially arranged in the upper end of the slump cone in a sleeving mode, the end, away from the material guiding barrel, of the supporting barrel abuts against the upper surface of the supporting ring.
