[0015] The following is a detailed description of the preferred implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0016] In the description of the present utility model, unless otherwise specified, "multiple" means two or more than two; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0017] like Figure 1-3As shown, a construction waste vibrating feeder of the present embodiment comprises an inclined hopper 1 and a vibrating device 2 for driving the hopper 1 to vibrate, a plurality of sieving holes 3 are arranged in parallel on the hopper 1, a dust collecting bag 4 is arranged at the bottom of the sieving holes 3 on the lower side of the hopper 1, the sieving holes 3 are long hole-shaped, and the direction of the sieving holes 3 is parallel to the length direction of the hopper 1, so as to facilitate the dropping of dust during the falling process, and during the vibrating feeding process of construction waste on the hopper 1, the dust will gradually move to the lower layer through vibration, and when the dust passes through the sieving holes 3, it can fall into the dust collecting bag 4 at the sieving holes 3 for collection, so as to avoid the dust falling into the crusher and being scattered in large quantities, thus avoiding harming the working environment and increasing the burden on the crusher; wherein the dust collecting bag 4 can be connected to the bottom of the hopper 1 by connecting parts such as hooks and Velcro, so as to facilitate disassembly and assembly, and the connecting parts are mature existing technologies and will not be described in detail here;
