Description

[Detailed Description of the Invention] Conventionally, a notch is provided at the bottom of a storage body supported on a machine frame.
It is already known that a beating body, which enters the storage body through an opening, is rotatably attached to a rotary body provided below the storage body, and the stored wood is hammered to debark the wood.

However, since the above-mentioned debarking machine strongly strikes the peripheral surface of the wood with the striking body, the wooden part may be damaged and the driving part of the striking body may be damaged due to the impact. The purpose of hammering is to strip the wood and circulate the wood. However, when a large, thick piece of wood is pounded, the reaction from the impact causes it to return in the opposite direction to the direction of rotation, so the wood does not circulate in itself. However, there were disadvantages such as the wood did not rotate, and even though the wood part was damaged on one side, there were parts that were not peeled off on the other side.

In addition, the thin material breaks due to the impact of the striking body and is wasted, and the fragile material also tends to lie sideways, creating an obstacle to circulation.

The present invention is aimed at improving the above-mentioned drawbacks, and includes providing an opening at the bottom of a storage body fixed to the machine frame, and installing rotary bodies in parallel at the bottom of the storage body, and A peeling plate that enters the storage body from one side of the opening and escapes from the other side of the opening is fixed to the outer periphery of the rotating body, and the distance between the outer periphery of the peeling plate and the center of rotation of the rotating body is It is characterized in that it is composed of successively larger portions and successively smaller portions, and that the outer circumferential surface of the peeling plate is provided with irregularities.

Hereinafter, the embodiment shown in the drawings will be described in more detail. FIGS. 1 and 2 show an example of the relationship between the peeling plate and the storage body.
It is a storage body with a discharge port 3 at the end, and has four openings in the circumferential direction at the bottom, and is hung horizontally on the machine frame 5 so that the discharge port 3 side is lower. .

Reference numeral 6 denotes a rotating shaft constituting a rotating body supported below the storage body 1. A triangular peeling plate 7 is fixed to the outer periphery of the rotary shaft with screws, and a corner 7a of the peeling plate 7 has a radius of It is formed in a small circular arc shape, and a circular arc shape part 7b with a large radius of curvature is formed between the adjacent corners 7a, and a large number of peeling protrusions 7C are provided on the entire circumferential surface.

Further, the portion where the distance between the outer periphery of the peeling plate 7 and the rotation center axis is the smallest substantially coincides with the opening 4 or
It protrudes a little inward, and the larger part penetrates into the storage body l through the opening 4 and pushes up the wood.

Reference numeral 8a is a scrap cutting blade screwed onto the end of the opening 4 on the scraping side, and cuts the wood chips or bark scraped by the peeling board 7.

Next, other examples of the peeling plate 7 will be explained with reference to FIGS. 3 and 4. FIG. 3 shows an example in which the peeling plate 7 has an oval shape,
Further, in the example shown in FIG. 4, a stripping plate 7 made of a disc is attached eccentrically to the rotating body 6, and a large number of protrusions 7c are attached to the outer peripheral surface of each plate.

In the above-mentioned embodiment, when the peeled wood is fed from the hopper 2 by an appropriate means and the rotating shaft 6 is rotated, the peeling plate 7... has the smallest distance from the center of rotation at point A, and the distance from the center of rotation is the smallest at point B. This combination of the fact that it is the largest and that it is integrated with the rotating body 6 forces the wood to be pushed up with this A-B while forcing the bark with the protrusion 7 C@e on the outer periphery. While the wood is firmly supported, it is pushed up and rotated upward from one side to the other, and between B and A, the distance from the center of rotation decreases as the wood descends under its own weight. The skin is peeled off by the protrusions 7C, which are gradually lowered.

The wood subjected to the peeling and rolling action is pushed up to the left in the drawing by parts where the distance from the center of rotation of the peeling plate 7 gradually increases and decreases, and then moves upward to the right. By creating a cycle of moving and descending, a uniform peeling action is rapidly applied to the entire circumferential surface of the wood, and the wood is sequentially transferred to the discharge port 3 and discharged.

Incidentally, even if the peeling plate 7 shown in the embodiment shown in FIGS. 2 and 3 is configured only by a portion whose distance from the center of rotation changes from small to large and small, the same peeling effect and transfer circulation can be obtained. effect can be obtained.

As described above, the present invention provides an opening at the bottom of a storage body fixed to the machine frame, and provides rotating bodies in parallel at the bottom of the storage body,
A peeling plate that enters the storage body from one side of the opening and escapes from the other side of the opening is fixed to the outer periphery of the rotating body,
The outer periphery of the peeling plate is constituted by a portion in which the distance from the center of rotation of the rotary body increases successively, and a portion in which the distance from the center of rotation of the rotary body gradually decreases. The peeling board that rotates integrally applies peeling and rotation to the wood both in the process of pushing it up and in the process of lowering it, and circulates the wood within the storage unit.Even if the wood is large in diameter and heavy, the transfer circulation is improved. It is possible to reliably remove the bark from the entire circumferential surface of the wood without damaging the surface layer of the wood.

It goes without saying that the present invention can be modified as appropriate within the scope of the claims.
