The punched waste material falls on the discharging plate 3-1 through the punching holes on the negative plate 4-2 and the upper bottom plate 1-2, the waste material is contacted with the ejector pins 3-11 on the discharging plate 3-1, the ejector pins 3-11 connect the waste material with the negative electrode of the power supply, and the ejector pins 3-11 accumulate electrons in the waste material.

After the waste falls on the discharge plate 3-1, the rope is driven by a power mechanism in the propulsion box 1-3 to slide in the chute and push the waste, and the rope uses the same pushing speed for all the waste so that the waste moves from the discharge plate 3-1 to the measuring plate 3-2.

After the waste material moves onto the measuring plate 3-2, the waste material is in contact with the energy transmission column 3-22, electrons in the waste material move into a lead through the energy transmission column 3-22, the current detection circuit detects the magnitude of current in the lead and transmits a detection result to the control system, the control system controls the sorting mechanism to enable the sorting mechanism to work, the waste material which can be secondarily processed and utilized is placed together, the waste material which cannot be reprocessed and utilized is placed at another position, and automatic discharge of the waste material is achieved through the rope and the work of the sorting mechanism.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
