This invention discloses a crushing device for recycling plastic particles from waste materials, relating to the field of plastic particle technology. It includes a crushing and recycling bin, a fixed motor fixedly connected to one side of the bin, and a connecting pipe fixedly connected to the other side. A feeding trough is fixedly connected to the top of the connecting pipe. An auxiliary feeding mechanism is installed inside the feeding trough. By using this mechanism, when a large number of plastic particles are fed into the feeding trough, an electric air pump is activated to blow air upwards rapidly. The electric air pump continuously blows air upwards through an annular jet vent at the top, creating an upward airflow at the center of the feeding trough. This allows the plastic particles, which accumulate in the feeding trough and fall through the gap between the electric air pump and the feeding trough, to be more evenly dispersed and fall. By continuously pushing the plastic particles, the problem of agglomeration, jamming, and clogging during the falling process is reduced.
