Sand screening device for civil engineering

Abstract

The invention discloses a sand screening device for civil engineering, which comprises a mounting plate, a support seat fixed on the mounting plate, a telescopic mechanism fixed on the upper side of the mounting plate, and a screening mechanism arranged on the upper end of the support seat. The upper end is located at the left and right ends of the support seat to fix the limit plate one and the limit plate two respectively. The support seat is a rectangular frame surrounded by the support block one and the support block two. The upper end of the support frame is provided with a sliding connection with the support block. The sliding track, the support block is provided with a rectangular groove along the length of its inner wall, and the bottom surface of the rectangular groove is equidistantly distributed with semi-cylindrical slide rail projections with openings downward. The screening mechanism includes a screening frame, which is arranged on the screening The cleaning mechanism in the frame, and the walking wheels symmetrically installed around the bottom of the screening frame, this device can not only improve the efficiency of sand screening, but also complete the cleaning of the screen mesh during the sand screening process, reducing the cost of sand screening , the sand screening effect is obvious, and it is very convenient to use.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a sand screening device for civil engineering. Background technique [0002] The sand used in civil engineering needs to be screened by a screening mechanism before use in order to screen the fine sand from the coarse sand and separate the soil and sand better. The ordinary screening mechanism is more complicated and inconvenient to operate. The mesh is easy to cause blockage, and it is necessary to stop the sand screening work regularly, disassemble the screen and manually clean the blocked mesh, which not only affects the screening efficiency, but also increases the cost of sand screening. The rain is easy to harden, which leads to incomplete sand screening during the screening process. Contents of the invention [0003] The object of the present invention is to provide a sand screening device for civil engineering to solve the problems raised in the above-mentione...
