Description

[Detailed Description of the Invention] This invention relates to a wood crushing device in which used desks, chairs, etc. are directly thrown into a rotating drum and crushed directly.

That is, in this invention, crushing blades are arranged at a constant interval on a rotating shaft horizontally suspended from the wood input port side to the wood chip discharge port side in the center of the rotating drum, and the crushing blades are connected from the wood input port side to the wood chip discharge port side. Desks, chairs, etc. (of course regular wood can also be used) are introduced into the rotating drum through the wood input port in a manner that increases the length of the wood toward the exit side, and the crushed blades rotating inside the rotating drum crush the input materials. This was developed for the purpose of providing a wood crushing device that crushes wood into pieces while stirring.

Now, one embodiment of the wood crushing device according to the present invention will be described based on the drawings. 1 is a rotating drum equipped with a rotating device, and 2 is a rotating shaft horizontally suspended within the rotating drum 1.

The rotary shaft 2 extends from the wood input port 3 side to the wood chip discharge port 4 side of the rotary drum 1, that is, the rotary drum 1
It is arranged parallel to the

Further, although the rotating drum 1 and the rotating shaft 2 may rotate in the same direction, it is preferable that they rotate in opposite directions to promote the stirring action of the input material within the rotating drum 1.

5 is a crushing blade arranged at a constant interval on the rotating shaft 2, and when installing this crushing blade 5 on the rotating shaft 2, the second
As shown in the figure, a support rod 6 is fixed to the rotating shaft 2, and this support rod 6
A crushing blade 5 is pivotally attached to.

The crushing blade 5 is made to gradually become longer from the wood input port 3 side to the wood chip discharge port 4 side.

This is because the material input from the wood input port 3 is a huge lump at the time of its introduction, so when it is suddenly thrown into the rotating drum 1, the crushing blades 5 engage with the material and the rotation is performed. This is to eliminate such phenomena.

In the figure, 7 is a belt conveyor disposed below the wood chip discharge port 4, and 8 is a secondary crusher disposed at the tip of the belt conveyor 7.

Further, 9 is a magnet disposed at the tip of the belt conveyor 7, and 10 is a belt conveyor disposed below the secondary crusher 8.

Then, the rotary drum 1 and the rotary shaft 2 are rotated, and a desired material is inputted from the lumber input port 3.

In this invention, it is planned to crush waste materials such as desks and chairs, but there is no need to limit it to these materials, and ordinary wood may also be used.

The input material in the rotating drum 1 is then crushed by the rotating crushing blade 5.

Since the crushing blades 5 are formed to be gradually longer from the wood input port 3 side to the wood discharge port 4 side, the input material is first crushed by the short crushing blades 5 and then gradually by the long crushing blades 5.
It will be crushed by

Moreover, since the rotating drum 1 is constantly rotating, even if the input materials are not all pulverized instantly, they are gradually and completely pulverized.

The crushed wood chips are then discharged from the wood chip discharge port 4,
The belt conveyor 7 is transferred to the secondary crusher 8, but before reaching the secondary crusher 8, the magnet 9
Metal pieces such as nails mixed with the wood pieces are thereby adsorbed and removed, and are further crushed by the secondary crusher 8.

This secondary pulverizer 8 is not necessary in theory, but it is expected that there will be some materials that are not sufficiently pulverized in the rotating drum 1, so it has a supplementary function for this purpose. .

Therefore, in this secondary crusher 8, wood pieces that have already been sufficiently crushed are not crushed further.

In other words, the degree of pulverization in the secondary pulverizer 8 is made uniform.

The wood chips discharged from the secondary crusher 8 are sent to a belt conveyor 10 for use.

As mentioned above, according to the wood crushing device according to this invention,
The desired input material is crushed by the rotation of the crushing blade, and the length of the crushing blade is designed so that it gradually increases from the input port side to the discharge port side, so that the crushing blade engages with the wood that is input. The occurrence of this phenomenon can be prevented, and since the rotary drum is rotated, the contents inside the rotary drum are stirred, thereby making the crushing uniform. Moreover, by reversing the rotation of the rotary drum and the crushing blade, the effect is further enhanced. The effects are remarkable.
