[0002] After retrieval, application number 202020750850.4 discloses a construction sand screening equipment, including a base and a screen box, two vertical support plates are welded on the upper end surface of the base, and slide grooves are opened on the opposite sides of the two support plates. There is no box wall on the top of the screen box, and a screen mesh is welded on the bottom of the screen box. The screen mesh is provided with an aperture adjustment device, and a steel plate is welded on the outer walls on both sides of the screen box, and the ends of the two steel plates away from the screen box are located in the slide grooves of the support plates on both sides and are slidably connected to the groove walls of the slide groove.

[0003] During use, a construction sand screening device in this patent application uses a motor to drive a screen barrel to screen the sand, so that the fine sand is discharged through the gaps on the screen barrel and the discharge port in turn and collected by a receiving box. However, during such use, the bottom of the screen barrel is blocked by the support plate, which reduces the screening efficiency of the screen barrel, and there are four groups of discharge ports arranged in a circular array about the center line of the horizontal plate. Two groups of receiving boxes are required to enclose and cooperate with the four groups of discharge ports for use. The operation is relatively cumbersome, which reduces the practicality of the device. For this reason, we propose a construction sand screening device. Utility Model Content
