Aggregate detection device

The embodiment of the invention discloses an aggregate detection device, which is characterized in that a controller is respectively connected with a sampling part and a dehydration part, and controlsthe sampling part to obtain an aggregate sample from an aggregate conveyor belt; and the dehydration part is used for dehydrating the aggregate sample. The controller is connected with a conveying part and controls the conveying part to uniformly and dispersedly convey the dehydrated aggregate sample to an image acquisition area. An image acquisition part is arranged on the side edge of the imageacquisition area and is used for acquiring a digital image of the aggregate sample; a weighing part is used for obtaining the sample mass of the aggregate sample; a user terminal is respectively connected with the image acquisition part and the weighing part and is used for carrying out aggregate analysis on the digital image transmitted by the image acquisition part so as to calculate the aggregate mass of the aggregate
