[0002] Wood fumigation refers to a technical method of using fumigants under controlled conditions to poison pests and their eggs in wood through their vapors. Fumigants are chemical agents that can produce gas concentrations that are lethal to pests at the required temperature and pressure.

[0003] For example, a wood fumigation device with authorization announcement number "CN220074978U" maintains a certain distance between the wood pieces through the interaction between the various components, and allows the device to adjust its limits according to the varying thicknesses of the wood, thereby enabling the device to perform a uniform fumigation process on the wood. However, after fumigating the wood, the wood temperature remains high, forcing workers to wait for the wood temperature to drop before fumigating the next batch of wood, thereby reducing work efficiency. Furthermore, when cooling the wood, the fixed position of the wood limits the contact area between the wood and the external wind source, thereby reducing the cooling effect on the wood. Utility Model Content

[0027] Working principle:

[0028] When it is necessary to fumigate the wood, the worker opens the frame door 11 on the frame 6, then places the wooden board in the block 7, and tightens the bolts on the block 7 so that its end is pressed against the wood to fix the board on the block 7. After all the boards to be fumigated are fixed on the block 7, the frame door 11 is closed, and then the external power supply of the cylinder 4 is turned on and started. The cylinder 4 drives the frame 6 to move downward, and then the wood in the frame 6 is moved into the box 9. After the frame 6 is moved into the box 9, the cylinder 4 is closed. At this time, the upper end of the box 9 is fitted together with the frame 6 (a sealing ring is provided on the upper end of the box 9, which can prevent air leakage at the joint between the box 9 and the frame 6, thereby increasing the air tightness). The sealing of the box body 9 is increased), and then the fumigators 10 on both sides are turned on. The fumigators 10 convert the water and Chinese medicine in the external water tank into high-temperature steam by heating and atomizing, and convert the water and Chinese medicine in the external water tank into steam and slowly release them into the box body 9 through the air outlet of the fumigator 10. The high-temperature steam generated by the fumigator 10 contacts the wood, and then fumigates the wood to achieve the effect of killing insects and preserving corrosion (during the wood fumigation process, the pressure relief valve 13 can be opened to discharge the air pressure generated in the box body 9 out of the box body, and the moisture formed in the box body 9 will be stored under the inner wall of the box body 9. After the wood fumigation work is completed, the water outlet 12 can be opened by the solenoid valve to discharge it out of the box body 9);

[0029] After the wood is fumigated, turn off the fumigators 10 on both sides.

[0030] Then, the cylinder 4 is started to retract its output end and drive the frame 6 to move upward to reset. After the frame 6 is reset, the cylinder 4 is closed. Then, the external power supply of the blowers 206 on both sides is connected and started. The blowers 206 on both sides blow wind to the fumigated wood to cool it down. The first servo motor 202 is started. The first servo motor 202 drives the rod 203 to rotate. The rod 203 rotates clockwise. The rod 203 drives the roller 204 to rotate. The roller 204 drives the slide to drive the protrusion 205 to swing clockwise (as shown in FIG. Figure 3 ), when the protrusion 205 drives the hair dryer 206 to swing 20 degrees clockwise, the first servo motor 202 reverses and drives the hair dryer 206 to swing in the opposite direction (the maximum swing angle of the hair dryer 206 is 25 degrees). In this way, the hair dryer 206 swings back and forth to adjust the blowing range of the hair dryer 206, thereby increasing the blowing range of the wood;

[0031] The external power supply of the second servo motor 302 is turned on and started. The second servo motor 302 drives the first gear 304 to rotate, and the first gear 304 drives the second gear 305 to rotate. (Since the first gear 304 has a smaller number of teeth than the second gear 305, the second gear 305 rotates slower than the first gear 304, thereby preventing the wood from rotating too quickly and reducing the time each surface of the board is exposed to wind.) The second gear 305 slowly drives the cylinder 4 to rotate, and the cylinder 4 causes the frame 6 to slowly drive the wood inside the frame 6 to rotate, thereby cooling the wood at different angles.

[0032] After the wood is cooled, the first servo motor 202 and the blower 206 are turned off, and the second servo motor 302 is turned off when the frame 6 rotates to the initial direction (as shown in FIG. Figure 1 ), then open the frame door 11, screw the bolts on the block 7 to separate its end from the plate, and then the worker manually removes the plate from the block 7. The fumigation work of the plate is completed in the above manner.

[0033] While the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
