Technical Field

[0001] The utility model relates to the technical field of single - shaft shredders, and particularly relates to a movable feed hopper type single - shaft shredder. Background Technique

[0002] A single - shaft shredder mainly consists of a blade main shaft, fixed knives, a bearing box body, a box body support, a feeding system, a hydraulic pusher system, a power system, and an electrical control system, and is mainly used for shredding waste materials such as wood, rubber, plastic, paper, etc.

[0003] The existing patent CN218554313U discloses a movable feed hopper type single - shaft shredder, including a single - shaft shredder box. An inlet is provided at the center of the end face of the single - shaft shredder box. A rectangular feed sleeve is slidably connected inside the inlet, and the end of the rectangular feed sleeve is fixedly connected to the bottom of a conical feed hopper. In the utility model, by operating the PLC controller to start the stepping motor and controlling the forward and reverse rotation of the stepping motor, after the stepping motor is started, it drives the precision lead screw to rotate. When the precision lead screw rotates, it drives the rectangular feed sleeve on the lead screw moving seat to reciprocate in the inlet, thereby realizing the left - right movement of the feed hopper, effectively solving the problem that the existing single - shaft shredder is a fixed - feed - hopper type shredder, and this structure will cause some materials to accumulate at the inlet of the single - shaft shredder during material transportation, ensuring the rate of materials falling into the shredder and the working efficiency of the shredder.
