The invention discloses a sand loading device for building
engineering construction. The device comprises rollers, an installing frame, a lead screw, a
shovel hopper, a driving base, a supporting plate, a fixed
pulley, a pull
rope, an installing plate, a stepping motor, a belt wheel, a take-up wheel, a spring base, a rack, a guiding hopper, an electric push rod, an installing frame, a sliding base, a clamping base, a connecting rod, a sliding rod, a supporting frame, a fixed plate, a positioning plate, a guide rod, a U-shaped adjusting rod and a rolling gear. The U-shaped adjusting rod is pushed, the U-shaped adjusting rod drives the sliding rod towards one end of the installing frame through the guiding rod, the sliding base and the connecting rod, the sliding rod drives the clamping baseto clamp the opening of the bag, in this way, the opening of the bag can be better clamped, the phenomenon that a sand bag opening is pulled open by one person is avoided, the working intensity of workers is greatly lowered, sand can be better loaded into a sand bag, the phenomenon that sand is shoveled into the sand bag again and again is avoided, the sand loading efficiency is greatly improved,a large amount of time is shortened, and meanwhile the practicability is enhanced.
