Currently, most leaves and branches pruned from trees or naturally fallen are transported to landfills for incineration or burial, requiring landscaping companies to spend significant funds on transporting and burning these branches. If waste branches, grass clippings, and other landscaping waste generated from garden maintenance and forest management are landfilled or incinerated as urban garbage, it not only leads to the waste of biomass resources and occupies land resources but also increases garbage disposal costs. The main crushing device of existing garden branch and leaf crushers suffers from low efficiency and an unreasonable overall structure. There is an urgent need in the market for a crushing device for garden branch and leaf crushers.
It can classify and process garden branches and leaves, with its special crushing device offering high efficiency. A crushing device for garden branch and leaf crushers, wherein the crushing device is installed inside the crusher. The crushing device includes a rotating crushing unit that receives vertical feeding and a rotating cutting unit that receives horizontal feeding and performs pre-cutting. The rotating cutting unit is positioned on one side of the rotating crushing unit.
Furthermore, the rotating crushing unit includes a crushing main shaft, cutting discs, fixed discs, and hammer piece assemblies. The crushing main shaft is fixed inside the crusher via bearing connections.
The cutting discs and fixed discs are respectively fixed at both ends of the crushing main shaft, with the hammer piece assemblies positioned between the cutting discs and fixed discs.
Furthermore, the hammer piece assemblies include multiple pin shafts, multiple hammer pieces, and spacing sleeves.
