Screening device for filtering concrete raw materials

The utility model relates to the technical field of concrete raw material screening, in particular to a screening device for filtering concrete raw materials, which comprises a vibrating box, the vibrating box is placed at a slope angle, a first filter sieve is fixedly mounted in an inner cavity of the vibrating box, and a second filter sieve is fixedly mounted in the inner cavity of the vibrating box. The first filter sieve is arranged right above the second filter sieve, and a vibrator is fixedly mounted at the bottom of the vibration box; according to the screening device for filtering the concrete raw materials, the first filter sieve, the second filter sieve, the bottom of the inner cavity of the vibration box and the vibrator are used in cooperation, and the working efficiency is improved through two times of screening; the problem that raw materials screened by an existing screening device need secondary screening is solved. 本实用新型涉及混凝土原料筛选技术领域的一种混凝土原料过滤用筛选装置，包括振动箱，所述振动箱呈斜坡角度摆放，所述振动箱的内腔固定安装有第一过滤筛，所述振动箱的
