2. A dual shaft shredder for solid waste treatment as claimed in claim 1 wherein: the induction extrusion blocks are located on one side of the extrusion induction groove and are fixedly provided with displacement arc heads, the displacement arc heads are arranged in the arc-shaped sliding grooves in a sliding mode, induction probes of the displacement induction devices extend into the arc-shaped sliding grooves, and when the extrusion induction blocks are pushed by broken materials to rotate around a rotating shaft to enter the extrusion induction grooves, the induction extrusion blocks push the displacement arc heads to slide in the arc-shaped sliding grooves and then are identified by the displacement induction devices.
3. A dual shaft shredder for solid waste treatment as claimed in claim 2 wherein: an air inlet groove is further formed in one side of the displacement arc-shaped head, the air inlet groove is communicated with the air pumping groove formed in the cutter head and the spindle, and the air pumping groove is communicated with an external air pumping device.
4. A dual shaft shredder for solid waste treatment as claimed in claim 3 wherein: the main shafts are respectively sleeved with a driving matched gear which is meshed with each other, one side of the main shafts are connected with the power output end of the speed reducer through a coupler, and the power input end of the speed reducer is connected with the driving shaft of the crushing motor through the coupler.
5. A dual shaft shredder for solid waste treatment as claimed in claim 4 wherein: the main shaft is kept away from the air feed cover that all overlaps of initiative cooperation gear one end and is equipped with fixed setting, offer on the main shaft with the pump gas pocket of blade disc position one-to-one, the air feed groove has been seted up to air feed cover one side, works as the line of tool bit top and axle center is located below the horizontal line and is alpha with the horizontal line contained angle, the pump gas pocket of this tool bit intercommunication is in the air feed inslot, thereby pumps the gas to corresponding clean downthehole through the intercommunication of external pump gas device and air feed groove.
6. A dual shaft shredder for solid waste treatment as claimed in any one of claims 1 or 5 wherein: the power device for driving the conveying of the material conveying belts is a conveying motor which is arranged in one-to-one correspondence, the conveying motor is electrically connected with a main control MCU, the main control MCU is in communication connection with a plurality of displacement sensing devices, and the displacement condition of the sensing extrusion block at the position of the cutter head is monitored through the main control MCU so as to control the work of the conveying motor.
