JPS5856487B2 - Wood inlet in drum barker - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wood inlet in a drum barker that can reliably debark wood and allow long pieces of wood to be input.

A drum barker is used to debark wood.It rotates a cylindrical drum, throws the wood into it, causes the wood to scatter, and uses friction between the pieces of wood to remove the bark. be.

However, this friction between the pieces of wood alone takes a long time.

Therefore, if possible, it is desirable to perform a peeling operation on the inlet portion before charging into the drum barker.

On the other hand, conventionally, when loading wood into a drum barker, a wood input port formed on a steep slope (400 degrees) allows the wood to fall into the drum barker under its own weight.

However, if the input port is steeply sloped, the wood that is being fed will also slope steeply, and the tip of the wood may hit the bottom of the drum barker's inlet, making it difficult to advance further, or in the case of long wood. The length of the wood that can be fed into the drum barker is limited by the diameter of the drum barker, and long wood has to be cut into short pieces before being fed.

Furthermore, in order to perform the debarking effect on the wood at the input port, it is necessary to gradually move the wood at the input port and prevent it from falling all at once.

Therefore, in this invention, the bottom of the U-shaped wood input port provided at one end of the main body of the drum barker is formed into a gently sloping shape, and a plurality of rotating shafts parallel to the bottom are arranged below the bottom. Disks with blades formed on the outer circumferential surface are arranged on this rotating shaft at regular intervals so that the blades of the disks face the top surface of the bottom, so that the wood is collected at the center of the bottom of the inlet. This was developed for the purpose of providing a wood inlet for a drum barker that allows the wood to be moved into the drum barker while peeling by rotating a disc, and also allows for the input of long pieces of wood.

Now, an embodiment of the wood input port in the drum barker according to the present invention will be described based on the drawings. Reference numeral 1 indicates a cylindrical drum barker body, and 2 indicates a wood slot provided at one end of the drum barker body 1. It is an input port.

This wood input port 2 has a U-shaped cross section and is formed with a gentle slope, and a hole 3 is bored in the bottom thereof.

Reference numeral 4 denotes a plurality of rotating shafts arranged in parallel with the bottom, and this rotating shaft 4 has a sprocket 5 arranged at one end, and this sprocket 5 is arranged on a motor 7 via a chain 6. sprocket 5'.

Reference numeral 8 denotes a disk disposed on the rotating shaft 4 at a constant interval, and a blade portion 9 is formed on the outer peripheral surface of the disk 8.

This blade portion 8 faces into the wood input port 2 through a hole 3 formed in the wood input port 2.

When the motor 7 is operated to rotate the disk 8 and wood is inputted from the wood input port 2, the disk 8
As the wood rotates, the wood is sequentially moved into the drum barker 1, and at the same time, the wood comes into contact with the blade 9 and is subjected to the debarking action.

Here, since the input port has a U-shaped cross section, the input wood naturally approaches the center of the bottom.

A plurality of rotary shafts are disposed below the bottom where the wood gathers in parallel with the bottom, and the disks 8 are disposed so that the wood can be reliably stripped of its skin.

As described above, according to the wood input port for a drum barker according to the present invention, the bottom of the wood input port having a U-shaped cross section is gently sloped, and a plurality of rotating shafts parallel to the bottom are arranged below the bottom. Since a disk with a blade formed thereon is provided, the debarking action can be performed effectively at the input port, and the disk also allows the wood to be reliably transferred into the drum barker.

In addition, since the wood input port is gently sloped, it is possible to input wood that is longer than before compared to the diameter of the drum barker, and there is no need to load the wood with momentum from a high position, so the wood input port can be placed at the height of the drum barker. In addition to being able to reduce the amount of wood that is required, it also occupies a smaller area than when wood is loaded horizontally.
