Title:
METHOD, DEVICE AND SYSTEM FOR DETECTING SLUMP, AND STIRRING-TYPE ENGINEERING MACHINE
Document Type and Number:
WIPO Patent Application WO/2021/253891
Kind Code:
A1
Abstract:
The present invention relates to the field of engineering machinery. Disclosed are a method, a device and a system for detecting slump, and a stirring-type engineering machine. The method comprises: determining whether the volume of concrete in a concrete container mounted on a roller of a stirring-type engineering machine is changed from a first preset volume to a second preset volume along with the rotation of the roller; under the condition that the volume is changed from the first preset volume to the second preset volume, determining a slump detection parameter corresponding to the concrete, wherein the slump detection parameter is the rotating time or angle of the roller when the volume is changed from the first preset volume to the second preset volume; and on the basis of the determined slump detection parameter and a preset correlation, determining the slump of the concrete, wherein the preset correlation is the correlation between the slump detection parameter and the slump. Therefore, the slump can be automatically detected without manual involvement.
