1results about How to "Realize hierarchical screening" patented technology

The utility model discloses a building sieve which comprises a shell, a fixing frame, a first sieve, a second sieve, a reciprocating screening mechanism and a tray, the fixing frame is placed at the upper end of the shell, the first sieve is arranged in the fixing frame, a first slot is formed in the inner wall of the shell and used for installing the second sieve, and a second slot is formed in the inner wall of the bottom and used for being connected with the slidable tray. The reciprocating screening mechanism is composed of a fixing frame, a cam, a driving motor and the like, the driving motor drives the cam to rotate, the fixing frame reciprocates on the shell, and meanwhile a vibration motor of the second screen enhances the screening effect. By means of the structure, the screen can efficiently screen building materials in a classified mode, materials with different particle sizes are effectively separated, the operation stability is guaranteed through the structural design of the screen, meanwhile, cleaning and maintaining are convenient, the screen can be widely applied to the fields of building construction, building material production and the like, and the screening efficiency and quality are improved.
