Concrete quantitative proportioning device

Abstract

The utility model discloses a kind of concrete quantitative proportioning device, including mixing box, mixing box top wall is provided with feeding pipe, mixing box inside is provided with sealing mechanism, sealing mechanism includes electric telescopic rod, the telescopic end of electric telescopic rod is rotatably connected with the lower surface of blocking plate, the end of electric telescopic rod away from blocking plate is rotatably connected on mixing box, the side of blocking plate close to mixing box is rotatably connected on mixing box inner wall, electronic weigher is embedded on blocking plate, mixing box is also provided with the guide plate of oblique setting. The utility model can make blocking plate flexible switching between first position and second position by the telescopic of first electric telescopic rod;When blocking plate is in first position, it is not only conducive to electronic weigher to accurately weigh cement, sand and other raw materials, but also can effectively prevent dust in mixing box from escaping to external environment;And when blocking plate is in second position, material can smoothly slide along guide plate and fall into mixing box.
