In the prior art, a screening box is usually slidably arranged inside the casing, and a protrusion that can eccentrically move is provided at the lower end of the screening box to knock its bottom, so that it moves up and down, so as to separate the concrete waste. However, in this method, the bottom of the screening box is frequently knocked, and the continuous physical impact will cause fatigue of the screening box material, accelerate wear, shorten the service life of the screening box, and increase maintenance costs and downtime.

[0003] For example, the utility model with publication number CN211538541U discloses a concrete waste separation device. In the technical solution of this patent, a screening box is provided at the upper end of the inner part of the casing, and a protrusion that can move eccentrically is provided at the lower end of the screening box to knock its bottom, so that the screening box moves up and down cyclically, thereby separating the concrete waste inside the screening box. However, in this method, the bottom of the screening box needs to be knocked frequently to make it move up and down. Long-term exposure to the knocking force will aggravate the metal fatigue of the screening box and its internal screen, which may cause the box body to deform or the screen to be damaged, shortening the service life, and then the screening box needs to be replaced frequently, affecting work efficiency.
