近時、オガ粉の需要分野は、きのこ栽培用、畜産用、有
機質堆肥用更には農水産物梱包用として急速に広がりつ

主体とする流通機構にあっては到底これに対応し得るも
のでゆなかった。(Prior Art) Recently, the fields in which sawdust is in demand are rapidly expanding for mushroom cultivation, livestock farming, organic compost, and packaging of agricultural and marine products. However, due to changes in the industrial structure, the supply of sawdust from sawmills, the traditional main source of supply, has drastically decreased, and the price has increased, making it difficult to maintain a stable supply. In addition, in various biomass industries, sawdust from more limited tree species is required, and it is impossible for the distribution system centered on the above-mentioned sawmills, where sawdust from various tree species is mixed in, to meet the demand. There was nothing that could handle this.
そこで最近になって、オガ粉専用の製造機が開発され実

るような処置も講じられるようになった。Recently, a manufacturing machine specifically designed for sawdust has been developed and put into practical use. Such a sawdust manufacturing machine has a cutting rotor in which a number of circular saws are fixed to a single shaft, and the wood to be treated is fed vertically to the rotor, which rotates once, and the wood is cut and processed to produce sawdust. It is manufactured by Then, the circular saw is made oblique or a part of the circular saw is bent obliquely and fixed to the shaft so that the cutting edge of the circular saw acts as evenly as possible on the surface to be treated of the wood. This is because if a circular saw is fixed in parallel as it is, even if a thin plate is produced, a large amount of sawdust cannot be obtained. Furthermore, as mentioned above, the cutting edge of a circular saw is placed diagonally with respect to the wood supply direction, resulting in severe wear and tear on the cutting edge, which is why measures such as silver-brazing cemented carbide tips are taken to the cutting edge. It became so.
（発明が解決しようとする問題点）
然し乍ら、上記の如く多数の丸鋸を軸装したローターを
用いる場合、丸鋸の刃先が縦長に供給された被処理木材
に対して斜めに配されている為。(Problem to be Solved by the Invention) However, when using a rotor equipped with a large number of circular saws as described above, the cutting edge of the circular saw is arranged diagonally with respect to the wood to be treated that is supplied vertically. For.
木材の繊維方向に交叉するように作用することとなり、
丸鋸の刃先に無理な力が加わり、且つ高速回転するので
その衝撃による騒音が極めて大でしかも堅い木材を切削

丸鋸を１枚づつ取り外さなければならずそのメンテナン
ス作業は大変煩わしいものであった。It acts in a manner that crosses the direction of the wood fibers,
Since excessive force is applied to the cutting edge of a circular saw and it rotates at high speed, the noise caused by the impact is extremely loud.Moreover, when cutting hard wood, the tip will be severely worn and damaged, making it unusable, and the worn circular saw will become unusable. In order to replace the saw, the circular saw must be removed one by one from the shaft, making maintenance work very troublesome.
本発明は上記実情に鑑みなされたもので、品質が均一で

がてスクリーン７の目より排出される。(Function) In the sawdust manufacturing apparatus having the above configuration, the wood W to be treated is placed vertically on the feeding conveyor 1 having an electric or mechanical speed change mechanism, and the cutting rotor 6 is placed on the conveyor 1.
fed to the side. Then, the wood W is held between the pinch roll 2 and the conveyor 1, and is further pressed by the piano touch-like holding member 3 and advances, and its tip hits the cutting rotor 6 that rotates at high speed. As it continues to progress, it is subjected to the shearing action of the cutting blades 5 and the fixed blade 4, and is finely cut. At this time, the wood W is subjected to a strong impact force due to the rotation of the rotor 6, but since it is held down by the pinch rolls 2 and the presser members 3, it is correctly struck in the radial direction of the rotor 6 without wobbling. In particular, since the piano-touch holding members 3 are individually swingable around the axis 20 of the pinch roll 2, the holding members 3 do not rest on the wood W even if the thickness of the wood W is large or small. ... descends due to its own weight and also serves as a guide, and the wood W is fed straight, so that the cutting blades 5 always act at right angles to the direction of the resin fibers of the wood W. also,
When the tip of the wood W hits the rotor 6, each of the cutting edges of the cutting blades 5 has a width in the thrust direction of the rotor 6 as described above, and also touches the circumferential body of the rotor 6 when viewed from the circumferential direction. Since the adjacent cutting blades 5 are arranged so that the gap between them is zero or they overlap, the tip of the wood W can be evenly cut by any of the cutting blades 5, and the above-mentioned always stable feeding of the wood W can be achieved. Together with this, sawdust with uniform particles of arbitrary particle size can be efficiently produced. The sawdust produced in this way is appropriately discharged through the holes of the screen 7, and the coarse particles that do not pass through the holes are subjected to the action of the cutting blade 5 in the narrow clearance between the screen 7 and the cutting blade 5. is finely crushed and eventually discharged from the screen 7.

A large number of cutting blades 5 are attached to the cutting rotor 6 in such a manner that they always strike the cutting rotor 6 correctly, and that there is substantially no gap in the thrust direction around the circumferential body of the rotor 6. Therefore, the tip of the wood to be treated is evenly cut by one of the cutting blades 5, and sawdust with a uniform particle size can be produced extremely efficiently.Moreover, the cutting blade 5
Since they are said to be removable, maintenance is extremely easy as you only need to replace worn parts. Furthermore, since a plurality of circumferential grooves 61 are recessed in the circumferential body of the rotor 6, wind is generated as the rotor 6 rotates, and this wind generation can be used to treat backboards and humid wood. Even in such a case, clogging of the screen 7 is significantly reduced, and overheating of the rotor 6 and cutting blades 5 is suppressed, which greatly contributes to reducing the frequency of wear and tear of these parts, and noise is also reduced.
