Mineral powder density detection device

The utility model discloses a mineral powder density detection device, and relates to the technical field of mineral powder detection. The device comprises a base, two symmetrically-arranged sliding grooves are formed in the top of the base, sliding plates are slidably connected into the two sliding grooves correspondingly, limiting rods are fixedly connected to the tops of the two sliding plates correspondingly, and the outer walls of the two limiting rods are slidably sleeved with first sliding sleeves correspondingly; the opposite sides of the outer walls of the two first sliding sleeves are fixedly connected with first connecting rods, and the other ends of the two first connecting rods are fixedly connected with arc-shaped supporting plates. When the mineral powder feeding device is used, the situation that the bottle body topples over to affect detection is avoided, mineral powder feeding can be well carried out on the Lee's pycnometer through the funnel, the telescopic cylinder is arranged, the positio
