Slump measuring device

The utility model relates to a slump measuring device, and relates to the technical field of slump measurement, the slump measuring device comprises a rack, a slump cylinder and a bottom plate are arranged on the rack in an up-down sliding manner, the bottom plate abuts against the bottom of the slump cylinder for sealing, and the sliding direction of the bottom plate is opposite to the sliding direction of the slump cylinder; and a driving mechanism for driving the slump cylinder and the bottom plate to move is arranged on the rack. The concrete is added into the slump cylinder, and after adding is completed, the driving mechanism is started to drive the slump cylinder and the bottom plate to be away from each other, so that the emptying time of the concrete in the slump cylinder is detected, the situation that local falling of the concrete is not uniform is reduced, and the detection precision of the slump is improved. 本申请涉及塌落度的测量装置，涉及塌落度的测量的技术领域，包括机架，机架上上下滑移设置有塌落度筒和底板，底板抵触在塌落度筒底部上进行封口且滑移方向和塌落度筒滑移方向相反，机架上设置
