Machine-made sand high-performance concrete proportioning device

The utility model discloses a machine-made sand high-performance concrete proportioning device which comprises a water storage tank, a water adding mechanism is arranged in the water storage tank, and a feeding mechanism is arranged on the surface of one side of the water storage tank. In the dry material pre-stirring stage, water is prepared and finally added, so that the quality of a concrete body is kept stable, the situation that the amount of water added manually is too large or too small is avoided, sand, cement and other raw materials in a hopper are transferred through a groove in the surface of a motor rotating discharging wheel, proportioning feeding is conducted from a discharging groove below, in the feeding process, a rotating rod drives a speed reducer to operate, and the speed reducer is driven by a motor to rotate. The speed reducer drives the threaded rod to rotate, the threaded rod drives the sliding plate to slide in the bottom groove, the amount of pre-stored water is increased, and after
