Wherein the motor 12 is of type Y90S-6.

The working principle is as follows: this sand screening plant for ready-mixed mortar need place the ready-mixed mortar raw materials inside feed hopper 2 in the in-service use of reality, then will drop under the effect of gravity and carry out the primary screening to the raw materials on first filter plate 4, what the primary screening was gone on is non-vibrations screening, main aim at with the building stones and the sand preliminary separation of large granule. The stabilizing frame 3 is used for stably connecting and supporting the first filter plate 4, and then the filtered raw material falls to the top position of the second filter plate 5 for secondary screening.

At this moment, the rotation of the motor 12 will drive the swing rod 13 to rotate, the swing rod 13 will drive the annular frame 14 to move left and right, the annular frame 14 will drive the linkage rod 15 to move left and right, the linkage rod 15 will drive the second filter plate 5 to move left and right, the second filter plate 5 drives the L-shaped support rod 9 to move left and right, the L-shaped support rod 9 will extrude the spring 8, the effect of stably extending and retracting the L-shaped support rod 9 is achieved, and therefore the second filter plate 5 can move left and right under the acting force of the motor 12 and the spring 8, so that the effect of vibration screening is achieved.
