Automatic sand screening equipment

Abstract

The invention discloses automatic sand screening equipment. A first hopper and a second hopper which can slide in the length direction of a bottom frame are arranged inside the bottom frame; the upperhalf part of a screen is rotationally connected with at least one first hydraulic pushing rod; the at least one first hydraulic pushing rod is movably connected with the bottom frame; and the first hopper or the second hopper is located below the screen. According to the automatic sand screening equipment, the screen having the adjustable inclination angle is arranged on the bottom frame to perform screening, and the two movable hoppers are arranged inside the bottom frame to store screened sand materials and sand materials requiring secondary treatment respectively; according to the equipment, adjustment of the inclination angle of the screen and movement of the hoppers are performed by the aid of the hydraulic pushing rods, screening and separation transferring of the sand materials canbe performed quickly, the automation degree of sand material screening and transferring work is increased, the requirement for human participation is reduced to the great extent, the labor force is liberated, a lot of human costs are saved, the sand material screening operation flow can be simplified, the screening time can be shortened, and the screening work efficiency can be improved effectively.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an automatic sand and gravel screening equipment. Background technique [0002] Sand and gravel are widely used in the field of engineering construction. According to the thickness of sand and gravel, sand and gravel can be applied to different types of engineering projects. In order to screen the sand and gravel according to the degree of thickness, different types of sand and gravel screening equipment are generally used to screen the sand and gravel in engineering construction. However, most of the sand and gravel screening equipment currently used in the industry requires a large number of workers to carry out auxiliary operations on site, which has the problems of high labor intensity and low automation, which will eventually lead to low screening efficiency and affect the construction period of the project.
