を段部に構成したことを特徴とするものである。The present invention aims to improve the above-mentioned drawbacks, and includes a rotating disc equipped with a rotating blade mounted on a shaft in a casing, and one side of the casing having a material inclined with respect to the rotating disc. A feeding cylinder is provided protrudingly, a receiving plate is attached to the lower surface of the material feeding cylinder at a portion that communicates with the casing, and a large number of protrusions are provided on the upper surface of the receiving plate substantially parallel to the material feeding direction. It is characterized in that a part or all of the protrusion near the casing is cut out from above over the entire width of the receiving plate, and a step is formed between the cut out part and the protrusion that is not cut out.

A plate-shaped rotary blade 5 is obliquely installed on the casing so that it can be adjusted forward and backward by a holding plate 6 and a screw 7. On one side of the casing, a spout 8 for feeding the material is approximately parallel to the plate surface of the rotary blade 5. The holes are drilled diagonally so that they intersect at right angles.

... are provided in large numbers, and the protrusions 10a of this receiving plate 10
The part close to the casing 2 is removed to create a smooth plate surface 1.
0b or by cutting off the top of the protrusion 10b so that the plate surface 10b has a height intermediate to that of the protrusion 10a, and a stepped portion 10c is formed between the protrusion 10a and the plate surface 10b. It is.
前述の装置において、スパウト８から送込まれた材料は

るので材料が後退することがない。In addition, a large number of parallel grooves are formed on the lower surface of the material by the above-mentioned protrusions, but when they reach the plate surface 10b, they are pressed by the rotary blade 5 during cutting and are restored to a somewhat flat shape. On the other hand, since the stepped portion 10c cuts into the material at an acute angle, the material does not retreat.
なお、受刃１２は省略する場合もある。Note that the receiving blade 12 may be omitted in some cases.
また、この実施例では主軸３を水平となしたがスパウト
８が水平となるように主軸３を傾斜させスパウト８の入

削することができる。As described above, the present invention includes a rotary disk equipped with a rotary blade mounted on a shaft in a casing, a material feeding tube protruding from one side of the casing that is inclined with respect to the rotating disk, and this material feeding tube. A receiving plate is attached to the lower surface of the inside that communicates with the casing, and the upper surface of the receiving plate is provided with a large number of protrusions that are approximately parallel to the material feeding direction, and the casing side of these protrusions are extended upward over the entire width of the receiving plate. Since a part or all of the material is removed and a stepped portion is formed between the removed portion and the unremoved protrusion, the protrusion 10a of the receiving plate 10 digs into the material during cutting and prevents the material from swinging laterally. However, the plate surface 10b is
While the receiver stops the irregularities on the surface of the material formed by a and flattens it, the step part 10c bites into the material at an acute angle and stops the receiver, and the material is intermittently and flattened by a rotating blade. The material does not retreat even when cut with an impact, and the inserted material can be stably cut to a predetermined tip length.
