[0003] Chinese Patent with Publication No. CN217449834U discloses a sand and gravel mixing device for building construction, which includes an outer cylinder. A rotating shaft group is installed in the middle of the outer cylinder. A first connecting sleeve is slidably sleeved up and down outside the rotating shaft group. Outside the first connecting sleeve, turning components are uniformly installed along its circumferential direction. The outside of the turning components is installed on a limiting ring. The lower end of the limiting ring is connected to the rotating shaft group through a connecting rod. A liftable lifting component is connected between the upper end of the first connecting sleeve and the upper end of the outer cylinder.
