[0025] Working principle: First, the device is installed in the required position via the mounting base 1 and connected to the main control device. A suitable number of quantitative mechanisms 3 are installed (the mounting base 301 is engaged with the mounting slot 209 on the rotating base 205 via the mounting block 302, and the quantitative mechanism 3 is installed by the positioning block 2010 and the locking bolt 2012). Various required materials (materials for fine aggregate apparent density testing) are stored in their respective storage cylinders 305. The quantitative mechanism 3 is connected to the adjustment mechanism 2 via the data cable 208. Then, various presets are made via the main control device. When the required material is needed, the servo motor 206 rotates the rotating base 205 (rotating one full revolution and then rotating in the opposite direction, cycling continuously) to align the laser emitter 3025 and laser receiver 204 of the corresponding material. Then, the electric telescopic rod 308 controls the sealing block 3016 to rise upwards within the conveying pipe 309, thereby facilitating the material flow. The lower end of the 09 internal vacuum seal guides the material in the storage cylinder 305 into the conveying pipe 309 (the second conveying pipe 3014 is closed under the restriction of the second one-way valve 3015, a FEMALE model integrated large-diameter one-way valve, and the first conveying pipe 3010 is activated under the restriction of the first one-way valve 3011, thus causing the material in the storage cylinder 305 to be adsorbed into the conveying pipe 309 under the action of vacuum negative pressure). When the electric telescopic rod 308 controls the sealing block 3016 to move to the preset height and stops operating, it then slowly pushes downward to push the material out through the second conveying pipe 3014 (the first conveying pipe 3010 is closed under the restriction of the first one-way valve 3011, and the second conveying pipe 3014 is opened under the restriction of the second one-way valve 3015, thus causing the material in the conveying pipe 309 to be pushed out under pressure). Under the action of gravity, it is collected in the collection hopper 3022, and with the pressure detection plate 3019 ( The Kistler 5069A series pressure sensor pad detects that when the pressure value is within a preset range due to the material reaching a preset quantitative value, the electric telescopic rod 308 stops, and the servo motor 3026 starts to flip the collection hopper 3022, thereby conveying the quantitatively measured material to the required container. Through cyclic operation, the material of different materials is quantitatively measured.
