[0021] In an optional embodiment: a traction motor 605 is fixedly installed on the top side of the base 100, and a driving gear 606 is fixedly installed on the output end of the traction motor 605.

[0024] It should be noted that the sliding movable rod 205 is restricted by the T-shaped slide groove 206 and the T-shaped slider 207 and can only move within a fixed range. The movable rod 205 can limit the extension direction of the sealing tarpaulin 200. The sealing tarpaulin 200 moves into the sealing liquid tank 300 under the traction of the counterweight bar 201.

[0026] It should be noted that the movement of the traction rope 604 is limited by the guide shaft 609 and the limiting sleeve 610 in the guide block 608 to prevent the traction rope 604 from deviating from the position.
[0027] In an optional embodiment: the drug circulation mechanism includes a delivery trough 400, a fumigant conveyor 401 is fixedly installed on the bottom inner wall of the delivery trough 400, a same fumigant conveying pipeline 402 is fixedly installed between the fumigant conveyors 401, the fumigant conveying pipeline 402 is connected to the fumigant delivery cabinet 500, a top support frame 403 is fixedly installed on the top of the fumigant conveying pipeline 402, and a load-bearing frame 404 is fixedly installed between the top support frame 403 and the bottom inner wall of the delivery trough 400.

[0029] It should be noted that the top support frame 403 and the load-bearing frame 404 on the base 100 can support the wood and leave a channel for air circulation. A fumigant conveyor 401 and a fumigant conveying pipe 402 are arranged in the delivery slot 400. The fumigant conveying pipe 402 conveys the fumigant to the inside of the fumigant conveyor 401 through the electronic valve 405. The bottom of the fumigant conveyor 401 can absorb a part of the air through the air vent 406. The air and the fumigant are fully mixed through the rotation of the fan 407, and then conveyed to the inside of the sealed tarpaulin 200. The fan 407 not only has the function of conveying the fumigant, but also can promote the flow of air inside the sealed tarpaulin 200 to ensure that the fumigant and the wood are fully mixed.
[0030] In an optional embodiment: the sealing tarpaulin 200 includes a wear-resistant layer 202, a base layer 203, and a sealing layer 204. The base layer 203 is the middle layer of the sealing tarpaulin 200 and is made of aramid base cloth. The sealing layer 204 is the inner layer of the sealing tarpaulin 200 and is made of silicone coating. The wear-resistant layer 202 is the outer layer of the sealing tarpaulin 200 and is made of polytetrafluoroethylene.
[0031] It should be noted that the sealing tarpaulin 200 is made of three materials: a wear-resistant layer 202, a base layer 203, and a sealing layer 204. The inner sealing layer 204 has good sealing and heat resistance, which can ensure the sealing effect of the sealing tarpaulin 200. The middle base layer 203 has high strength, which can enhance the overall toughness of the sealing tarpaulin 200, so that the sealing tarpaulin 200 can adapt to repeated folding during use and extend its service life. The wear-resistant layer 202 has high wear resistance, which can prevent the sealing tarpaulin 200 from being damaged externally.
[0032] In an optional embodiment: a fumigant delivery cabinet 500 is fixedly installed on the base 100, a control panel 501 and a movable door 502 are arranged on the fumigant delivery cabinet 500, a fumigant storage tank 503 and a fumigant atomizer 504 are placed in the control panel 501, an output end of the fumigant atomizer 504 is connected to the fumigant delivery pipeline 402, a sealing liquid delivery cabinet 700 is fixedly installed on the base 100, a sealing liquid tank 701 and a sealing liquid pump 702 are arranged in the sealing liquid delivery cabinet 700, a pipeline is connected between the sealing liquid pump 702 and the sealing liquid tank 300, and a liquid level sensor 703 is arranged in the sealing liquid tank 300.
[0033] It should be noted that, in the fumigant delivery cabinet 500, the fumigant in the fumigant storage tank 503 is gasified by the fumigant atomizer 504 and transported to the fumigant conveyor 401, while the liquid in the sealing liquid tank 300 is monitored by the liquid level sensor 703 and replenished in time by the sealing liquid pump 702 and the sealing liquid tank 701.
[0034] Working principle of the present invention: When using the device, firstly, the sealing tarpaulin 200 needs to be raised by the traction motor 605 to facilitate the staff to place the wood on the base 100. After the placement is completed, the traction motor 605 is started, and the output end of the traction motor 605 drives the driving gear 606 to rotate. The rotation of the driving gear 606 will also drive the driven gear 607 to rotate. The driving gear 606 and the driven gear 607 rotate in opposite directions. The rotating driving gear 606 and the driven gear 607 respectively drive the rotating rod 602 to rotate. The rotating rotating rod 602 releases the traction rope 604 through the winding ring 603 thereon, so that the movable rod 205 connected to the end of the traction rope 604 slides between the fixed mounting frame 101, and the sliding movable rod 205 is affected. The sealing tarpaulin 200 can only move within a fixed range due to the restriction of the T-shaped slide groove 206 and the T-shaped slider 207. The movable rod 205 can limit the extension direction of the sealing tarpaulin 200. The sealing tarpaulin 200 moves into the sealing liquid tank 300 under the traction of the counterweight bar 201. The sealing tarpaulin 200 and the counterweight bar 201 are in contact with the sealing liquid in the sealing liquid tank 300, so that the inside of the sealing tarpaulin 200 becomes a sealed environment. The movement of the sealing tarpaulin 200 is also restricted by the limiting rod 301 on the inside. At the same time, the fumigant sensor 302 arranged on the limiting rod 301 can detect the fumigant concentration inside. The movement of the traction rope 604 is restricted by the guide shaft 609 and the limiting sleeve 610 at the guide block 608 to prevent the traction rope 604 from deviating from the position. The top support frame 403 and the load-bearing frame 404 on the base 100 can support the wood and leave a passage for air circulation. A fumigant conveyor 401 and a fumigant conveying pipe 402 are arranged in the delivery slot 400. The fumigant conveying pipe 402 conveys the fumigant to the inside of the fumigant conveyor 401 through the electronic valve 405. The bottom of the fumigant conveyor 401 can absorb a part of the air through the air vent 406. The air and the fumigant are fully mixed through the rotation of the fan 407, and then conveyed to the inside of the sealed tarpaulin 200. The fan 407 not only has the function of conveying the fumigant, but also can promote the flow of air inside the sealed tarpaulin 200 to ensure the full mixing of the fumigant and the wood. The sealed tarpaulin 200 partially adopts a wear-resistant layer 202, a base layer 203, and a sealing layer 2 04 The three materials cooperate with each other. The inner sealing layer 204 has good sealing and heat resistance, which can ensure the sealing effect of the sealing tarpaulin 200. The middle base layer 203 has high strength, which can enhance the overall toughness of the sealing tarpaulin 200, so that the sealing tarpaulin 200 can adapt to repeated folding during use and extend its service life. The wear-resistant layer 202 has high wear resistance, which can prevent the sealing tarpaulin 200 from being damaged on the outside. In the fumigant delivery cabinet 500, the fumigant atomizer 504 is used to vaporize the fumigant in the fumigant storage tank 503 and transport it to the fumigant conveyor 401, and the liquid in the sealing liquid tank 300 is monitored by the liquid level sensor 703, and is replenished in time by the sealing liquid pump 702 and the sealing liquid tank 701.

10. The fumigation process for abrasion-resistant and corrosion-resistant oak bark according to claim 1, specifically comprising: Step 1: Preprocessing Wood inspection: remove surface dirt, bark, and rotten parts to ensure uniform penetration of the agent. Moisture content control: The moisture content of the wood must be ≤20%. Too high a moisture content will reduce the penetration efficiency of the fumigant. For stacking, the wood should be stacked at least 5 cm apart in a "well" shape to ensure gas circulation. Chemical impregnation pretreatment: Mix boric acid (concentration 5-10%) with ethanolamine and soak the wood for 4-6 hours to enhance the insect and anti-corrosion ability. The temperature needs to be controlled at 40-50°C. Then use low molecular weight phenolic resin (10-15% solution) for impregnation. After curing, the hardness and wear resistance of the wood will be improved. The immersion process needs to be in a vacuum state, -0.08MPa for 30 minutes, and then pressurized to 0.5MPa for 2 hours to ensure deep penetration; Surface nano-modification, spraying nano-silicon dioxide on the wood surface ( ) or zinc oxide (ZnO) suspension to form a protective layer against wear and UV rays, and then dried at 60°C for 2 hours to allow the nanoparticles to bind to the wood fibers; Step 2: Sealed environment construction Use a dedicated fumigation site, dedicated fumigation room, container or cover with airtight tarpaulin (thickness ≥ 0.15mm), conduct sealing test before use, use smoke bombs or pressure test (maintain negative pressure for 10 minutes without obvious leakage); Step 3: Fumigant placement Drug selection, methyl bromide ( ): Fast and efficient, but it damages the ozone layer and has been gradually restricted (special permission is required). Aluminum phosphide (AlP): produces phosphine ( ), suitable for long-term closed environment, corrosive to metal; Composite agent, copper-ethanolamine (Cu-EA) solution (ratio 1:100) is added to sulfuryl fluoride, copper ions are released during fumigation to inhibit fungal growth, silane (such as KH-550) is mixed with fumigant, the hydrophobicity of wood surface is enhanced, and the sulfuryl fluoride dosage is increased by 10% (such as the original 40g / m³ is adjusted to 44g / m³) to offset the effect of the composite agent on penetration efficiency; Dose calculation: Methyl bromide: 30-50g / m³ (at temperature ≥10℃, sealed for 24 hours), aluminum phosphide: 5-10 pieces / ton (3g per piece, decomposition takes 12-24 hours); Step 4: Fumigation Temperature: The best range is 20-35℃. If the temperature is lower than 10℃, the fumigation time needs to be extended (50% time extension for every 5℃ drop). Humidity: Relative humidity is 60-80%. If it is too low, spray water mist to adjust. Sealing time: Thin board (≤5cm): 24-48 hours, thick wood (>5cm) or serious insect pests: more than 72 hours. Fumigation with compound agents, keep the environment closed after fumigation, gradually raise the temperature to 120-150℃, and continue for 4-6 hours (thermal modification) to promote the degradation of wood hemicellulose, improve dimensional stability and hardness, and the heating rate is ≤5℃ / min to avoid wood cracking. The humidity is controlled at <15% throughout the process to prevent deformation caused by thermal degradation; Step 5: Ventilation and safety testing after fumigation Forced ventilation: Use a fan to continuously ventilate for 8-12 hours to ensure that the residual agent concentration is less than 5ppm (methyl bromide) or less than 0.3ppm (phosphine); Detection method: Gas detector: real-time monitoring of fumigant residues; Biological indicators: Place sensitive insects (such as longhorn beetle larvae) to verify the killing effect.
