――― Treatment of wood ―――
In the wood processing system of the present invention, wood is chipped as follows.
(1) The self-propelled wood crusher 100 and the wind power sorter 1 are appropriately installed at a place where wood is processed.
(2) The self-propelled wood crusher 100 and the wind power sorter 1 are activated, and the wood to be processed is put into the hopper 111 of the self-propelled wood crusher 100.
(3) The wood put into the hopper 111 is made into chips by the self-propelled wood crusher 100 and put into the sorting device 4 of the wind power sorter 1.
(4) The dust put into the sorting device 4 of the wind power sorter 1 is separated and removed by the sorting device 4 and discharged to the lower part of the wind power sorter 1.
Hereinafter, the processing content in the wood processing system of this invention is explained in full detail.

  When the self-propelled wood crusher 100 is activated, the hydraulic motors 112b, 113b, 114b, and 121b are respectively driven by the pressure oil from the hydraulic pump 123b. When the wind power sorter 1 is activated, the electric motor 31 and the driving motor 41 are driven.

  The wood put into the hopper 111 of the self-propelled wood crusher 100 is conveyed to the front of the self-propelled wood crusher 100 by the feed conveyor 112. The wood transported forward by the feed conveyor 112 is sandwiched between the belt 112a of the feed conveyor 112 and the belt 114a of the press conveyor 114, and is pushed into the crushing unit 113 located in front of the conveyors 112 and 114, to form chips. It is crushed into the shape At this time, dusty fine powder (hereinafter referred to as dust) is also generated.

  The wood crushed into chips by the crushing unit 113 is put into the sorting device 4 of the wind power sorter 1 installed in front of the self-propelled wood crusher 100 by the discharge conveyor 121 together with the dust. The metal piece mixed in the wood chip is removed by the magnetic separator 122 during the conveyance by the discharge conveyor 121.

  In the wind power sorter 1, the air sucked from the intake port 33 of the blower 3 is discharged from the discharge port 34. As shown in FIG. 11, the air (arrow B) discharged from the discharge port 34 passes through the hole 431 a of the screen 431 facing the blown air inlet 444 from the blown air inlet 444 of the cover 44 and passes through the hole 431 a of the screen 431. Air is blown to the inner periphery. And it is sent to the outer periphery of the screen 431 from the hole 431a of the screen 431 facing the exhaust port 446. That is, on the inner surface of the screen 431, ventilation is performed in the horizontal direction from the blown air inlet 444 toward the exhaust outlet 446.

  When the wood chip and the dust are input into the sorting device 4 of the wind power sorter 1 as indicated by an arrow C shown in FIG. 11, they fall in the sorting unit 43, but in the process of falling, In the selection unit 43, air (arrow B) blown from the blower 3 is received from the side. Among the wood chips and dust that have been put into the sorting device 4, the dust is sent to the outer periphery of the screen 431 from the hole 431 a of the screen 431 facing the exhaust port 446 along with the flow of air blown from the blower 3. (Arrow D).

  The wood chip from which the dust component has been separated by receiving the flow of air discharged from the blower 3 is larger than the diameter of the hole 431a of the screen 431, and therefore is not sent to the outer periphery of the screen 431 from the hole 431a. The inner surface of the cylinder 42 is dropped (arrow E).

  The air containing the dust component sent to the outer periphery of the screen 431 from the hole 431 a of the screen 431 facing the exhaust port 446 is sent to the inlet pipe 51 of the cyclone 5. The air containing the dust flowing in from the inlet pipe 51 of the cyclone 5 is swirled inside the outer cylinder 52 (arrow F), and the dust is separated. The separated dust is discharged from the rotary valve 54 to the lower part. The clean air purified by separating the dust is discharged to the outside from the outlet pipe 53 (arrow G).

  The cylindrical portion 42 and the sorting portion 43 are rotationally driven around the shaft 42 a by the drive motor 41. Therefore, the screen 431 always moves, and alternately faces the blowing air inlet 444 and the exhaust outlet 446. That is, the relative positional relationship between the screen 431 and the air flow passing through the screen 431 changes. For this reason, the air discharged from the blower 3 may flow from the outer surface of the screen 431 toward the inner surface or the inner surface of the screen 431 toward the outer surface in the hole 431a of the screen 431. That is, the direction of the airflow passing through the hole 431a is alternately reversed.

  There is a case where the hole 431a is blocked and clogging occurs, for example, a wood chip that is flowed by an air flow from the inner surface to the outer surface of the screen 431 is stuck in the hole 431a. However, when the rotating screen 431 moves to a position facing the blowing air inlet 444, the wood chip that closes the hole 431a by the airflow flowing from the outer surface of the screen 431 toward the inner surface (arrow B in FIG. 11) is on the inner surface side of the screen 431. Pushed out. That is, the screen 431 is back-washed at the position facing the blown air inlet 444 by the air discharged from the blower 3.

The wood processing system of the present invention has the following effects.
(1) By throwing the wood chips crushed by the self-propelled wood crusher 100 from the upper part of the sorting unit 43 having a perforated plate processed into a cylindrical shape, the wood chips and the dust are separated. Thereby, the processing speed of the wood chip containing dust is increased.
(2) The inner surface of the screen 431 is vented in the horizontal direction from the blown air inlet 444 toward the exhaust outlet 446. Thereby, dust can be efficiently separated from the wood chips that fall vertically.

(3) The screen 431 moves with respect to the airflow passing through the inner surface of the screen 431 from the blown air inlet 444 toward the exhaust outlet 446. Therefore, since the holes 431a separating the dust from the wood chips are sequentially replaced, the dust can be separated from the wood chips by the holes 431a that are not clogged, and problems such as a reduction in processing amount can be prevented.

(4) The screen 431 is rotationally driven with respect to the airflow passing through the inner surface of the screen 431 from the blown air inlet 444 toward the exhaust outlet 446, and the direction of the airflow passing through the hole 431a is alternately reversed. Thereby, since the clogged hole 431a can be backwashed, the dust can be separated for a long time.
(5) Since wood is processed by the self-propelled wood crusher 100 and the wind power sorter 1, dust can be removed from the produced wood chips. Thereby, since dust does not fly in the air at the time of conveyance of the produced | generated wood chip, handling property improves.

(6) The self-propelled wood crusher 100 is self-propelled, and the wind power sorter 1 is processed in a state in which the blower 3, the sorting device 4, and the cyclone 5 are integrated with the frame 2. It can be removed from the site and mounted on a vehicle. As a result, it can be quickly installed at the processing site and is highly convenient.

――― Modifications ――――

For example, the blower 3 may be disposed between the sorting device 4 and the cyclone 5, and the inlet 33 of the blower 3 may be connected to the outlet conduit 53 of the cyclone 5. In this case, piping may be provided so that the air discharged from the blower 3 is supplied to the blown air inlet 444 of the sorting device 4.

(2) In the above description, the screen 431 is driven to rotate all around, but the present invention is not limited to this. The screen 431 may repeat the forward partial rotation and the reverse partial rotation. In this case, what is necessary is just to set the rotation angle of the screen 431 so that the screen 431 is backwashed with the ventilation air from the air blower 3. FIG. In addition to the blown air from the blower 3, a means for blowing backwashed blown air to the screen 431 may be separately prepared. That is, any structure may be used as long as the dust and the wood chips can be separated by the screen that has been backwashed to eliminate clogging. In this case, the movement of the screen 431 is not limited to the rotation around the shaft 42a.

  For example, as shown in FIGS. 12A to 12D, instead of the above-described screen 431, a cylinder 436 having an opening on the side surface, an arc-shaped screen 437, and an actuator 438 that is a moving means of the screen 437 are provided.

The upper and lower portions of the screen 437 are plate portions 437a and 437c having no openings, and the upper and lower plate portions 437a and 437c are screen portions 437b capable of passing air. The screen 437 is provided in the vicinity of the exhaust port 446, and the screen 437 can be moved up and down by the actuator 438 (FIGS. 12A and 12B). And the screen part 437b moved to the backwashing positions 436a and 436b is backwashed with the backwashing air by periodically raising and lowering the screen 437 (FIGS. 12 (c) and 12 (d)). May be.

  In addition, since only the screen 431 needs to move with respect to the airflow generated by the blower 3, the cylindrical portion 42 and the sorting portion 43 may be fixed as shown in FIG. For example, if the sorting unit 43 is not a cylindrical shape but a square tube shape, the moving direction of the screen 437 described above may be the left-right direction.

(3) Contrary to the above description, the screen may be fixed and the direction of the airflow by the blower 3 may be configured to move relative to the screen. For example, the screen 431 may be fixed, and portions corresponding to the blowing air inlet 444 and the exhaust outlet 446 of the cover 44 may be configured to move with respect to the screen 431.

(4) In the above description, the screen 431 has a cylindrical shape with a circular cross section, but the present invention is not limited to this. A cylindrical shape having a polygonal cross section may be used.
(5) In the above description, the cyclone 5 is used for collecting the dust separated from the wood chip, but the present invention is not limited to this. Depending on the particle size of the dust component, for example, any dust collector such as a gravity dust collector, an inertial dust collector, a cleaning dust collector, a filtration dust collector, and an electric dust collector can be used.
(6) The above-described embodiments and modifications may be combined.

  In the above embodiment and its modifications, for example, the selection means corresponds to the selection unit 43, the ventilation means corresponds to the blower 3, and the collection means corresponds to the cyclone 5, respectively. The changing means and the rotating means are realized by a drive motor 41, sprockets 413, 414, and 415, chains 418 and 424, a cam follower 426, and a roller 427. Furthermore, as long as the characteristic functions of the present invention are not impaired, the present invention is not limited to the device configuration in the above-described embodiment.
