Problems solved by technology

[0002] At present, in most construction projects, the sorting of the fine sand used in the project is still carried out with traditional sieves. The existing technology is to screen the fine sand, usually before the sand heap that has been transported in advance. , artificially sprinkle sand on the screen, and screen the sand through the filtration of the screen, which is complicated, time-consuming and labor-intensive, and the screened sand has to be loaded and transported to other places again, which is a waste of time; the existing screening machine vibrates The amplitude is large, and the noise generated is also large, which affects the surrounding environment. When the existing screening machines are used, they are all directly filled, without a speed-limiting structure, and the screening effect is not good and the screening is not thorough.

Abstract

The invention discloses a convenient and fast type noise-reduction classified sand screening device for civil engineering and a used method thereof. The convenient and fast type noise-reduction classified sand screening device comprises a screening box, pushing rods, supporting pillars, damping cylinders, rolling wheels, a material discharging plate, a material discharge plate, a feeding assembly,a screening assembly, first supporting plates, cylinder cavities, installing frames, second rotating discs, damping springs, a rubber rod, a wheel disc, a motor, a supporting rod, a screening plate,an oblique beam, an inserting block, an inserting hole and a second fixed cylinder barrel; and the pushing rods are arranged on one side of the side wall of the screening box. According to the convenient and fast type noise-reduction classified sand screening device for the civil engineering and the used method thereof, the screening plate is arranged into horizontally shaking screening, the vibration amplitude of the screening device is reduced, the generation of noise is reduced, and meanwhile, with the assistance of the damping springs, better noise reduction effect can be achieved; the feeding assembly is arranged, the feeding speed can be changed by changing the rotation speed of a first motor, complete screening can be ensured, and the screening effect is better; and a knocking rod intermittently knocks on the second fixed cylinder barrel, the vibration of the screening plate can be realized, and clear of filtering holes of the screening plate can be ensured.

Description

technical field [0001] The invention relates to the technical field of sand screening equipment, in particular to a convenient noise-reducing classification sand screening device for civil engineering and a method for using the same.
