Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a cutter shaft installation device for a lawnmower. Background technique [0002] Knife roller grass cutter is a traditional product, which is used to cut various grass raw materials in the material preparation section of pulp and paper making enterprises. Its cutter roller assembly includes a cutter roller and a plurality of flying knives running through the cutter roller evenly arranged on the circumference of the cutter roller. Grass material in the cutting area is cut. For cutting brittle raw materials such as wheat straw, the uneven knife-edge gap has little effect, but it has a greater impact on cutting tough raw materials such as straw and asparagus, resulting in continuous cutting or poor cutting quality at places with large gaps, which cannot meet the requirements. Subsequent section requirements. The support rigidity is low, which affects the working efficiency a...
