The method as claimed in claim 1, wherein when the blocking height approach switch is triggered again and the material block on the capturing frame is not guided to the crushing cavity by the capturing and discharging cylinder, the crushing motor increases the working efficiency to drive the crushing roller to accelerate the impact decomposition of the material block.
4. The method for processing the large materials in the material conveying process as claimed in claim 1, wherein a crushing elastic rod is arranged at the power output end of the crushing driving hydraulic cylinder so as to realize flexible driving of the lifting of the crushing roller.
5. The method as claimed in claim 1, wherein if the material pieces in the crushing chamber cannot be decomposed, the separate discharging mechanism on the crushing chamber is used for guiding the material which cannot be decomposed in the crushing chamber out of the crushing chamber;
the specific process is as follows: the crushing roller is positioned at the uppermost end of the crushing cavity under the action of the crushing driving hydraulic cylinder, and the material separation window at the inner end of the crushing cavity is opened by the separation valve plate under the action of the valve driving hydraulic cylinder; the separation plate gets into through the separating groove on the terminal surface before smashing the chamber and smashes the intracavity under the effect of separation pneumatic cylinder, and under the vertical drive effect of separation pole, the separation drive spout on the terminal surface will smash the material piece of intracavity and derive through the material separation window along smashing the chamber before the separation board.
6. The method as claimed in claim 1, wherein in step S3, the capturing frame falls on the capturing material guiding plate, and the capturing material guiding plate is rotated by the capturing material guiding motor to guide the material to the crushing chamber.
7. The method as claimed in claim 6, wherein the capturing material guiding plate senses whether the material block falls on the capturing material guiding plate through a material guiding pressure sensor arranged on the capturing material guiding plate.
8. The method as claimed in claim 1, wherein the capturing frame is provided with a material receiving pressure sensor to detect whether the material block enters the capturing frame.
9. The method as claimed in claim 1, wherein the capturing box is provided with a discharge detection switch to detect whether the material block enters a designated position in the capturing box under the driving of the capturing frame.
