9. A method of using an aggregate bulk density testing device as defined in any one of claims 1 to 7, comprising the steps of:
step one: aggregate with density to be measured is put in the scraper component (30) until the aggregate is completely filled in the weighing container (28) and covers the upper surface of the stacking plate (23), and then the put of the aggregate to be measured is finished preliminarily;
step two: the hydraulic rod (33) is started, the scraper (34) is driven to move leftwards when the hydraulic rod (33) is started, in the process, the scraper (34) contacts the vertical plate (35) and the surface of the stacking plate (23) to push redundant aggregate covered on the upper end of the weighing container (28) to the baffle (15) to fall, and the aggregate in the weighing container (28) is enabled to be flush with the upper end surface of the weighing container (28);
step three: the motor (41) is started, the motor (41) starts to drive the gear (43) to rotate, and the gear (43) rotates and simultaneously drives the rack (45) to rotate, so that the whole of the connecting plate (44) and the stop block (25) is forced to move downwards;
step four: the stop block (25) moves downwards, the sliding rod (22) and the stacking plate (23) move downwards integrally, the spring (24) is compressed, the upper end face of the stacking plate (23) is forced to be separated from the limiting block (32), the stacking plate (23) and the weighing container (28) move downwards integrally until the upper end face of the clamping groove (29) contacts the weighing scale (50), the weighing container (28) is separated from the stacking plate (23), and the weighing scale (50) is used for weighing the weighing container (28) and aggregate therein;
