Description

[Detailed description of the invention] This invention relates to the drum bar force, and more specifically, by rotating the cylindrical rim and providing a spindle approximately at the center of the support body for the drum bar force excluding the bark, this support body is This relates to the force of a drum bar that can be swung in a see-saw manner.

In the production of chips, the drum bar force for removing the bark of pine and other chip logs is provided with a rotatable edge on a support via at least two support/rotation mechanisms, and
The drum bar force is configured so that as the edge body rotates, the log moves while hitting the notch protruding inside the edge body, and the drum bar force is used to debark the bark of the chip log placed in the edge body. has been done.

However, with this conventional structure, the logs become stuck in the notch inside the frame, preventing them from moving toward the exit or bending, and although they make a lot of noise, their structure makes it difficult to debark. There are drawbacks such as poor performance.

The purpose of this invention is to eliminate the above-mentioned conventional drawbacks, and its features are that the edge body is rotatably provided on the support body via at least two support/rotation mechanisms; By configuring the drum bar force so that as the edge rotates, the log moves while hitting the notch protruding inside the edge, and by providing a fulcrum at approximately the center of the support, the support can be moved. The drum bar is configured to be able to swing in a see-saw manner together with the edge, and to provide a drum bar force that controls the movement of raw wood using gravity.

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

Figure 1 is an external view of the drum bar force of this invention. A plurality of guide roller mechanisms 5 arranged on the machine frame 4
It is composed of a rim 7 which is rotatably supported by the rim member 7 and rotated by the power transmission mechanism 6.

Although the power transmission mechanism is not shown, it includes a motor and a speed reducer mounted on the frame member 4 via a support, between the pulley of the motor and the pulley of the speed reducer, and between the pulley of the speed reducer and the main body of the can. It consists of a belt, etc. that is hung between the pulley and the pulley.

As shown in FIG. 2, the rim 7 has a pair of rails and a pulley attached to the outside of the can main body 7, and has numerous notches protruding from the inside.

Note that at one end of the support 1 there is a hopper 11 into which chip logs are fed.
However, a shooter 12 is attached to the other end.

The drum bar force of this invention has the above-mentioned structure, and the procedure for peeling the bark of a chip log using this drum bar force will be described below.

First, the edge body 7 supported by the guide roller mechanism 5 on the support body 1 is rotated by the power transmission mechanism 6, and the third
As shown in the figure, the support body 1 is held in a posture with the hydraulic jacks 91 and 92 disposed below both ends of the support body 1 so that the chute 12 side is slightly lowered around the spindle mechanism 3, and the edge body 7
The bark of the log is stripped using the notches installed inside.

When raw chips are fed into the hopper 11 by the force of the drum bar, which performs such an operation, the raw chips are gradually transferred from the hopper 11 side to the chute 12 side by the rotation of the rim 7 and the scraping of the chip logs by the notches in the rim. The bark is scraped off by the notches.

Therefore, while the chip log reaches the chute 12 side within the edge, it repeatedly and violently hits the notch, and the bark is peeled off.
The stripped bark and torn pieces of wood are discharged from the edge 7.

If the bark is not peeled enough, use a hydraulic jack 91.92
Using this, raise the chute 12 side in the opposite way as described above, lower the hopper 11 side, perform the same operation, lower the chute 12 side again, raise the hopper 11 side, and discharge the chip logs to the chute side to completely debark the wood. I can do it.

As described above, this invention has a rim rotatably provided on the support via at least two supporting/rotating mechanisms, and a notch protruding into the rim that rotates as the rim rotates. By configuring the drum bar force so that the raw wood moves while bumping against it, and by providing a fulcrum at approximately the center of the support, the support is configured to be able to swing in a see-saw manner together with the edge. There is little noise, and since the support body to which the edge body is attached can perform see-saw movement, the progress of the chip logs can be accelerated in the edge body and the wood chips can be reciprocated, so complete debarking can be carried out efficiently.

[Scope of utility model registration request] The edge body is rotatably provided on the support body via at least two support/rotation mechanisms, and as the edge body rotates, the log is moved while hitting a notch protruding inside the edge body. By configuring a drum bar force at the center and providing a fulcrum at approximately the center of the support body, the slope angle of the support body can be set in a see-saw manner together with the edge body through a tilt angle control member such as a jack. The power of the drum bar.
