Description

[Detailed description of the invention] This invention relates to drum bar force, and more specifically, a rotary peeling tool (Rotatsukatsuta) in which cutting blades are formed on the circumferential surface in each gap between a plurality of rotating wire bodies that rotationally transport wood. This relates to the force of a drum bar that is inserted and rotated to forcibly strip wood.

In this invention, a plurality of rotary separating bodies are arranged in series with a slight gap, and a drum-shaped rotary cutter is installed below the gap to debark the raw wood being transferred within the wire sphere. The cutters are two truncated conical cutters facing each other on the small diameter side, and the drum bar force allows these opposing cutters to rotate in the same direction or in different directions. The present invention provides a drum bar force characterized in that a common rotating shaft is supported at its center and both ends by bearings fixed to mounting members, respectively.

An embodiment of this invention shown in the drawings will be described in detail below.

Figure 1 is a diagram showing the overall structure of the drum bar force of this invention.
A to 1C are a plurality of rotating bodies, each of which is mounted on a roller 4 supported by a bearing 3 on a base 2 via a rolling wheel 5 attached to the outer periphery of the rotating body. The wood put into the rotating body 1C from the wood input hopper 6 installed at one end of the frame is applied by a drive mechanism (not shown), and is moved within the rotating edges 1b and la by rotation in the direction of the arrow. It can be taken out from the wood discharge lower installed at the other end.

Reference numeral 8 denotes a rotary cutter device, one end of which is pivotally supported by a shaft 91 at the end of a vertical member 90 forming the mounting machine frame 9, and a spring, etc. A rotating shaft 80 and its bearings 81 to 83 are attached to a mounting member 94 which is elastically mounted via an elastic member 93.
Two truncated conical rotary cutters 84°85
The rotary cutter 84 between the bearings 81 and 82 is fixed to the shaft 80, and the rotary cutter 85 between the bearings 82 and 83 can rotate with respect to the shaft 80. Pulleys 86 and 87 are attached to the end of the shaft 80 and the large diameter side of the rotary cutter 85, respectively, and motors 88 and 89 attached to the attachment member 94 drive power transmission means such as a belt. It is configured to be able to rotate independently through the

As shown in FIG. 3a, l), the rotary cutter 84.85 has a large diameter portion approximately 1/6 of the diameter of the rotary separation body, and the length of the two rotary cutters 84.85 is A truncated cone-shaped body 841, 851 with a length slightly longer than 1/2 of the diameter of the rotary body is made of steel, and a substantially V-shaped blade (single-edged or double-edged) 842, 852 is provided on its surface. One or more wires are attached in a spiral shape, and the fuselage 84
1 has a hollow shaft 846 provided with a keyway through end plates 843, 845, and a body 851 has bearings 853, 85.
A pulley mounting shaft 856 is attached via the end plate 855 and the pulley mounting shaft 855 .

The rotary cutter device 8 is shown in FIGS. 1, 2 and 4.
As shown in the figure, most of the total length of the rotary cutter device 8 is inside the rotary housing due to the interval 10 which is wider than the diameter of the large diameter side of the rotor 11 cutter 84.85 provided between the rotary compacts 1a to 1C. It is inserted through the mounting machine frame 9 at an inclination angle of approximately 40°, and a fixed circular body 13 is provided in the gap 12 remaining on both sides of the rotary cutter 84, 85, and this fixed circular body also serves as a roller cutter cover. gap cover 14
is installed.

Incidentally, the part indicated by reference number G in FIG. 2 is a fixed guide member.

When the wood W is continuously fed into the rotating line ball 1C from the wood input hopper 6 shown in FIG.
The rotating wire is given an agitating motion such that it is lifted along the wall of the rotating wire body and then falls, and gradually moves toward the discharge lower.

During this movement, blades 842 and 852 of rotary cutters 84 and 85, which are inserted between the rotary bodies through the gap 10 and rotated individually via power transmission means by motors 88 and 89, cut into the wood W as shown in FIG. It bites into the side of the wood that is moving while rolling at right angles to the wood, scraping the bark, and the two work together due to the collision of the fixed notch 15, making it possible to effectively strip wood with hard bark such as small-diameter trees, frozen water trees, and walnut trees. I can do it.

This rotary cutter 84.85 is for the small diameter wood described above.

If the tree is frozen or hard, the motor 88 should be rotated in the normal direction.
Rotate the motor 89 in the reverse direction and rotate the rotary cutter 84°85 in the correct direction.
Effective debarking can be achieved by rotating the motors 88 and 89 in the forward direction, while rotating the motors 88 and 89 in the forward direction in the case of large-diameter water or wood whose bark easily peels off.

Rotary cutter 84.8 due to a large amount of wood clogging the input port side.
When an excessive load is applied to the shaft 5, the elastic member 93 is deflected and the mounting member 94 is moved back around the shaft 91, thereby avoiding the excessive load.

As described above, this invention consists of arranging a plurality of rotary bodies in series with a slight gap between them, and placing a drum-shaped shape at the bottom of the gap to which the raw wood to be debarked is transferred in the wire sphere. A rotary cutter is provided, and this cutter has two truncated conical shapes facing each other on the small diameter side, and the two opposing cutters can be rotated in the same direction or in different directions by improving the drum bar force. The raw wood is stripped by rotating frusto-conical rotary cutters in the same direction or in different directions, so stripping is done efficiently, but an abnormal load is applied to the common rotation axis through each cutter. In the present invention, the rotating shaft is supported at the center and both ends by bearings fixed to the mounting member, so that the abnormal load applied to the common rotating shaft is shared, preventing damage to the common rotating shaft, and reducing the force of the drum bar. It has the effect of maintaining smooth operation for a long time.
