Sand pile and sand grain detection trolley based on Internet of Things

The invention relates to the field of engineering detection, in particular to a sand pile and sand grain detection trolley based on the Internet of Things. The trolley comprises a storage water outlet mechanism and is characterized in that a moving mechanism is arranged on the lower side of the storage water outlet mechanism, an upper side baffle is arranged on the front side of the moving mechanism, a sampling detection mechanism is slidably connected to the inner side of the moving mechanism, and an upper side hydraulic rod is fixedly connected to the front side of the storage water outlet mechanism; a hydraulic rod is arranged on the side, away from the storage water outlet mechanism, of the upper side hydraulic rod, and a front side baffle component is fixedly connected to the hydraulic rod; and the storage water outlet mechanism is designed as a rectangular box body. According to the invention, sampling detection can be carried out at each height and depth of a sand pile, and a plurality of samples can b
