Description

[Detailed Description of the Invention] A. Purpose of the Invention (Field of Industrial Application) The present invention relates to a chipper for producing chips for pulp raw materials, building materials, fuel, and other uses from wood.

(Prior art) As shown in FIG. 4, a chipper conventionally used for manufacturing wood chips has a receiving blade 20 fixed to a spout base 17 with a bolt 21 so as to be movable back and forth in correspondence with a cutting blade 19 of a rotary disk 18. , the spout 22 is fastened to the spout base 17 with bolts 23 so as to be movable forward and backward, with the receiving blade 20 being straddled, and the hanging blade 2 is attached to the inclined surface 24 of the spout 22 with its lower end in contact with the receiving blade 20.
5 is fixed.

(Problems to be Solved by the Invention) In the conventional chipper described above, when adjusting the receiving blade 20 and the hanging blade 25 in and out in order to change the size of chips to be manufactured, the receiving blade 20 is first moved forward and backward to make the cut. The distance between the spout 22 and the blade 19 is determined, and then the spout 22 is moved forward and backward according to the amount of movement of the receiving blade 20.
Since the adjustment was made so that the relative position between the receiving blade 20 and the hanging blade 25 was always maintained constant, the adjustment operation was troublesome and time-consuming, and the relationship between the receiving blade 20 and the hanging blade 2
5 and 5, there was a problem in that it was extremely difficult to keep the relative position of the two constant at all times.

This invention was made to solve the above-mentioned conventional problems, and by separating the hanging blade from the spout and making it work together with the receiving blade, it is easy and quick to adjust the insertion and removal of the receiving blade and hanging blade. The purpose of the present invention is to provide a chipper in which the relative position of the two does not change even when the chipper is used.

B. Structure of the invention (means for solving problems) The chipper according to the invention includes a cutting blade 5 attached to a rotary disk 1, a receiving blade 7 and a hanging blade 13 corresponding to the cutting blade 5, and a supply of material. In the chipper A equipped with a spout 10, the hanging blade 13 is separated from the spout 10 and is formed integrally with a mounting piece 14 that overlaps the receiving blade 7.

(Function) The chipper configured as described above has a receiving blade 7 and a hanging blade 1 in order to change the size of chips to be manufactured.
3, when adjusting the forward or backward movement of the bolt 9 that fixes the receiving blade 7 and the mounting piece 14 of the hanging blade 13 to the spout base 6.
When you loosen the and let out the receiving blade 7, the mounting piece 14 will be attached to it.
The hanging blade 13 on which the mounting piece 14 rests is also extended in the same way, and when the receiving blade 7 is retracted, the hanging blade 13 on which the mounting piece 14 rests is also extended.
are also retracted in the same way, so when the distance between the receiving blade 7 and the hanging blade 13 matches the dimension to obtain the desired chip, tighten the loosened bolt 9 and retracting the receiving blade 7 and the hanging blade 13. If it is fixed to the spout stand 6, the receiving blade 7 and the hanging blade 13 can be adjusted in and out easily and quickly, and at this time, the relative position between the receiving blade 7 and the hanging blade 13 remains constant without changing. It is something that can be preserved.

(Example) Next, an example of implementation of the chipper related to the present invention will be described based on the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a rotary disk in the chipper A, which is supported by a shaft 2. This rotary disk 1 is provided with a large number of blade holes 3, and each of these blade holes 3 is provided with a back blade 4. A cutting blade 5 is attached.

Reference numeral 6 denotes a spout stand provided on one side of the rotary disk 1 described above, on which a receiving blade 7 corresponding to the cutting blade 5 described above is mounted so as to be adjustable forward and backward by a mounting bolt 9 that engages with a long hole 8. be.

Reference numeral 10 denotes a spout attached to the spout stand 6 by bolts 11 so as to straddle the receiving blade 7, and is adapted to supply material diagonally to the rotary disk 1 along its inclined surface 12.

Reference numeral 13 denotes a hanging blade, which is provided at the lower part of the sloped surface 12 of the spout 6, separate from the sloped surface 12 and with the same slope as the sloped surface 12, and a mounting piece 14 which overlaps the receiving blade 7.
This mounting piece 14 is provided with a long hole 15 that fits the receiving blade 7, and the mounting bolt 9 of the receiving blade 7 described above is passed through the long hole 15 to connect the mounting piece 14 and the receiving blade 7. It is fixed to the spout base 6 by tightening it together.

16 is the mounting piece 1 of the above-mentioned receiving blade 7 and the hanging blade 13.
After combining the receiving blade 7 and the hanging blade 13 with the connecting bolt with the connecting bolt 4 so that there is a required dimensional difference between the cutting edges of both, the receiving blade 7 and the mounting piece 14 are tightened, and the receiving blade 7 and the hanging blade 1 are assembled.
3 are always operated in unison.

In the chipper A shown in the above embodiment, the hanging blade 13 is separated from the spout base 6 and is integrally formed with the mounting piece 14 that overlaps the receiving blade 7. When the forward and backward adjustments were made, the hanging blade 13 was also adjusted forward and backward, and the preset relationship between the two blade edges was always maintained constant and did not change unless it was intentionally changed.

C. Effects of the invention In the chipper according to the invention, the forward and backward movement of the hanging blade is adjusted as well as the forward and backward movement of the hanging blade, so that the adjustment operation is easily performed and does not take much time.

When the receiving blade and hanging blade are adjusted forward and backward at the same time, the relative position of the blade edges of both blades does not change, and an appropriate state can always be maintained.

Adjustments can be made easily because there is no need to move the heavy spout.

It has the following unique effects.
