[0034] In the electronic waste recycling equipment provided by the utility model, the electronic waste is sent into the recycling box 1 from the feed port 1b, and the electronic waste is first sent to the filter plate 3 after being crushed by the crushing roller 2. The crushed materials that meet the size requirements are sent to the heating bucket 4 through the filter holes 3a of the filter plate 3, so that the heating bucket 4 can separate organic matter and metal, while the crushed materials with larger volume slide down along the inclined direction of the filter plate 3 and are finally discharged from the return port 1c. The operator sends the crushed materials output from the return port 1c into the feed port 1b again, so that the crushing roller 2 can fully crush them, improve the heating efficiency of the heating bucket 4, and further improve the metal separation efficiency.

The connecting hole 5a is connected to the filter hole 3a of the filter plate 3 to form a material passing channel, wherein the adjusting plate 5 can also move along the inclination direction of the filter plate 3 to adjust the size of the material passing channel.

[0036] In this embodiment, the size of the material passage is adjusted by moving the adjustment plate 5 along the tilting direction of the filter plate 3, that is, the particle size of the crushed material that can enter the heating bucket 4 can be adjusted according to actual needs, so as to meet the needs of screening different types of electronic waste and improve practicality.

[0037] In one embodiment, the recovery box 1 is further provided with an adjustment port in the inclined direction of the filter plate 3, and the adjustment port and the return port 1c are located on two opposite sides of the recovery box 1. One end of the adjustment plate 5 extends out of the inner cavity 1a from the adjustment port for the operator to drive, and the other end extends to the side wall of the inner cavity 1a where the return port 1c is provided.

After the material in the return hopper 8 is full, the plug-in plate 81 of the return hopper 8 is pulled out from the installation port, and the empty return hopper 8 is installed on the installation plate 12. Then, the return hopper 8 filled with crushed material is moved to the feed port 1b to dump the crushed material therein, thereby improving convenience.
