Problems solved by technology

[0007] However, if the replacement is performed every 24 hours, it is necessary to replace the blade almost every day, and continuous operation cannot be performed.
In addition, the cost of the blade itself also increases, and the cost increases

Embodiment 1

[0024] First, an example of a wind blade will be described using figures. For the air shovel 11, the air shovel 1 rotates at a high speed inside, and when the bamboo 3 is delivered to the inside of the air shovel 11 by the conveying roller 2, the air shovel 1 hits the bamboo 3, and the bamboo is cut off. The cut bamboo hits the blade or the like again inside the wind shovel 11 and is atomized. There is a filter screen 4 at the lower part of the wind shovel 11, and the bamboo that has been atomized into a size smaller than the filter screen 4 is discharged to the outside.

[0025] However, because bamboo has a cylindrical shape with a hollow inside, when the wind blade 1 hits the bamboo material 3 (before deformation), the substantially circular shape is deformed into an elliptical cross section by a compressive force. , and become the state of 5 after bamboo deformation. In addition, even if it is a slat-shaped bamboo cut in the vertical direction, the same deformation occur...

Abstract

The present invention provides a micronization device of bamboo and a micronization method, which can inhibit the shot life of a blade even the bamboo is micronized. The micronization device of the bamboo has an air chipper (11) for cutting strip shaped bamboo (3); and a bamboo opening device (9) which is used as a configuration device for configuring the inside and the outside of the strip shaped bamboo (3) guided in the air chipper (11) to face the same direction. Moreover the micronization method of the bamboo arranges the inside and the outside of the strip-shaped bamboo to face the same direction, and cuts the bamboo in a manner that the blade always enters the bamboo from the inside.

Description

technical field [0001] The present invention relates to an apparatus and method for pulverizing bamboo and micronizing bamboo for fertilization, production of activated carbon from bamboo charcoal, modification, and the like. Background technique [0002] In the case of fertilizing bamboo and making charcoal from bamboo as activated carbon, it is necessary to pulverize the bamboo and use a device called a wind shovel. According to the purpose and use, the size of the particles can be changed through the hole size of the filter inside the wind shovel. [0003] However, the life of the blade of a common air shovel is more than 100 hours if it is general wood, and it is 24-30 hours in the case of bamboo, which is extremely short. [0004] In addition, as a patent document disclosing a bamboo wind shovel, there is, for example, JP-A-2013-154588 (Patent Document 1). [0005] prior art literature [0006] Patent Document 1: Japanese Patent Laid-Open No. 2013-154588 [0007] Ho...
