Plant fiber blade shredder

Abstract

A plant fiber blade shredder includes: a rotating wheel with a drive shaft passing through the center of a plurality of circular plates; a plurality of inner blade holders and inner blades arranged around the outer periphery of the circular plates, with the blade extension direction of the inner blades forming an angle of 1 to 10 degrees with respect to the axial direction of the drive shaft; a housing supporting the drive shaft and having a discharge channel connected below; and a cover covering the housing; the cover having a plurality of outer blades fixed parallel to each other, all of which extend through outer blade grooves into the outer periphery of the rotating wheel, creating a plurality of shearing gaps between the inner and outer blades, allowing the inner and outer blades to gradually cut into the plant fibers at an oblique direction, thereby effectively reducing instantaneous cutting resistance and minimizing the occurrence of plant fiber entanglement, pulling, or incomplete cutting.

Claims

1. A plant fiber blade shredder, comprising: A rotary wheel includes a drive shaft, a plurality of circular plates, a plurality of inner cutter holders, and a plurality of inner blades. The drive shaft passes through the center of the circular plates, which are spaced apart along the axial direction of the drive shaft. The inner cutter holders are spaced around the outer periphery of the circular plates and are disposed between at least two of the circular plates. Each inner blade is detachably fixed to its corresponding inner cutter holder, and the cutting edge of each inner blade extends at an angle of 1 to 10 degrees relative to the axial direction of the drive shaft. A housing includes a base, a cover, and a mesh. The base supports the drive shaft and has a discharge channel connected to its lower part. The cover is fitted onto the base housing, and the cover and the base housing together form a receiving space for accommodating the rotating wheel. The cover has a feed inlet at the top and a plurality of parallel outer blade grooves. Each outer blade groove has an outer blade holder on one side, and each outer blade holder has an outer blade fixed thereon. The blade extension direction of the outer blade is parallel to the axial direction of the drive shaft. The outer blades all extend into the receiving space through the outer blade grooves and are located on the outer periphery of the rotating wheel, so that a plurality of shearing gaps are formed between the inner blade and the outer blade. The mesh is installed inside the base housing and is spaced between the rotating wheel and the discharge channel.

2. The plant fiber blade chopper as claimed in claim 1, wherein the inner blade has a plurality of first elliptical holes and is secured to the inner blade holder by a plurality of first bolts passing through the first elliptical holes.

3. The plant fiber blade chopper as claimed in claim 2, wherein the outer blade has a plurality of second elliptical holes and is secured to the outer blade holder by a plurality of second bolts passing through the second elliptical holes.

4. The plant fiber blade shredder as claimed in claim 3, wherein a transparent window is provided on one side of the housing, the transparent window corresponding to the shearing gap between the inner blade and the outer blade, so that the operator can view the shearing gap through the transparent window and adjust the relative position of the outer blade and the inner blade, thereby changing the size of the shearing gap.

5. The plant fiber blade chopper as claimed in claim 4, wherein the cover has a pivot end and an open end opposite to each other, the pivot end being pivotally mounted on the base housing, the open end being able to open the cover relative to the base housing to switch the cover from a closed state to an open state, and in the open state, the rotor is exposed to allow the operator to adjust the relative position of the inner blade and the inner blade holder.

6. The plant fiber blade shredder as claimed in claim 1, wherein the mesh body is mesh-shaped and has a plurality of holes, each hole having an equivalent aperture between 1 mm and 3 mm, so that plant fibers shredded to the corresponding size can pass through the mesh body and enter the discharge channel.

7. The plant fiber blade shredder as claimed in claim 6, wherein an airflow generator is installed at the discharge channel to generate a guiding airflow in the discharge channel, so that the plant fibers passing through the mesh are driven by the guiding airflow and discharged from the discharge channel.

8. The plant fiber blade shredder as claimed in claim 1, wherein a first motor and a second motor are respectively connected to both ends of the drive shaft by a belt, and the first motor and the second motor jointly drive the drive shaft to rotate.

9. The plant fiber blade shredder as claimed in claim 8, wherein the first motor and the second motor are stacked vertically on the outside of the impeller, thereby reducing the installation space occupied by the first motor and the second motor in the horizontal direction.

10. The plant fiber blade shredder as claimed in claim 1, wherein a conveyor belt is provided above the feed inlet, and one of the discharge ends of the conveyor belt corresponds to the feed inlet for conveying and feeding unchopped plant fibers into the feed inlet.
