AI Technical Summary
Technical Problem
The blades of traditional weed shredders are prone to breakage due to collisions with hard objects at high speeds. The material is not tough enough, resulting in frequent replacements, long downtime, and high maintenance costs.
Method used
Made of 65Mn spring steel and subjected to isothermal quenching, combined with shock-absorbing washers and modular structural design, the tool's impact resistance is increased, and stress is dispersed through the transition section and the working section at the tool tip, reducing the fracture rate.
Benefits of technology
It significantly reduces the blade breakage rate, decreases the frequency of tool replacement, reduces downtime and maintenance costs, and improves the operational stability of the equipment.

Abstract
The utility model provides a novel wild grass rubbing crusher's flail cutter, including flail axle, tool rest and flail, be provided with tool rest on flail axle, install flail on tool rest, the flail includes two, two flails are mirror image setting, the flail includes the tool root section, transition section and the knife tip operation section that are connected in proper order in proper order, the tool root section is set through hole, the through hole is equipped with the shock pad ring, the shock pad ring is threaded and is equipped with bolt, and the both ends of bolt are connected on tool rest. The utility model discloses the flail cutter, when colliding, produces tangent force through transition section, and transition section and knife tip operation section can reduce radial impact load, thereby make stress dispersion rate promote, improve the anti -impact of tool rest, reduce blade fracture rate significantly, reduce tool rest replacement frequency, reduce downtime, reduce maintenance cost.
