[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. The present invention provides a multifunctional cutting component and a knife holder in a three-spiral shape, thereby effectively reducing the cutting resistance compared with the prior straight knife drum, making the crushing and cutting process continuous and reducing the cutting impact load. The present invention provides replaceable blades and hammers, so that when tree trunks, branches and stumps are chipped and crushed, all blades can be installed inside the knife holder; when template waste and furniture waste such as small iron nails, sand and gravel are used, all hammers can be installed inside the knife holder; when branches, trunks and stumps are crushed and the crushed materials are used as organic coverings for urban landscaping, a mixed installation method of blades and hammers can be used inside the knife holder to improve the crushing and chipping capacity.
[0015] 2. The present invention provides a dustproof component, and by installing the mounting frame and the filter between two connecting plates, it is possible to prevent debris from flying into the knife drum during the crushing process. When disassembly is required, the mounting frame is moved to one side through the disassembly slot on the top of the mounting frame to disengage the card block from the slot, and then the mounting frame is pulled outward to disengage the positioning plate from the positioning slot, thereby taking out the mounting frame and the filter, and the filter can be cleaned or replaced.
[0016] 3. The present invention sets a ventilation cooling component when the main shaft is running. The rotation of the main shaft drives the fan blades to rotate. The air is sucked in from the through hole at one end of the air inlet cylinder through the rotation of the fan blades. The air enters the gap between the main shaft and the air inlet cylinder from the ventilation holes on the side wall of the air inlet cylinder through the internal guide member of the main shaft. Finally, the air is discharged through the exhaust port on the side wall of the main shaft. In this way, the heat inside the main shaft is discharged through the exhaust port, thereby achieving the effect of cooling the main shaft and preventing the main shaft from being damaged due to excessive temperature.
[0017] 4. The present invention sets a protective component. When the main shaft is running, the main shaft rotates to generate centrifugal force to make the mounting part slide toward the inner wall of the main shaft through the mounting column, so that air can enter through the through hole on one side of the air inlet tube. When the main shaft stops rotating, the centrifugal force slowly disappears, and the mounting part moves into the air inlet tube under the action of the spring on the side wall of the mounting column and the spring on the side wall of the mounting rod, and finally the air inlet tube is closed, which can prevent various impurities from entering the inside of the main shaft.
