[0044] In this embodiment, in order to improve the penetration effect of the protective agent in the soaking pool, a sealing groove 11 is opened on the top of the soaking pool 1, and a sealing strip 21 that cooperates with the sealing groove 11 is arranged at the bottom of the cover plate 2. The cover plate 2 is connected with a vacuum tube 8 and a pressure tube 9 (both are telescopic tubes), and a disc heating tube 10 is installed at the bottom of the inner cavity of the soaking pool 1, wherein the cooperation of the sealing groove and the sealing strip can ensure the sealing of the soaking pool, and the vacuum tube cooperates with an external vacuum pump to evacuate the soaking pool, so that the bamboo can be pre-treated by vacuum suction, and then the soaking pool is pressurized by the pressure tube and the external pressure pump, and the protective agent is heated and insulated by the disc heating tube at the same time, so that after vacuum and pressurization treatment, the protective agent penetrates into the interior of the original bamboo from the inner circle of the original bamboo (bamboo yellow) with the highest nutrient content and the lowest density, which greatly improves the penetration speed and penetration amount of the protective agent.

[0045] In this embodiment, in order to ensure the sealing of the interior of the immersion pool and only use one set of motors for lifting control and dynamic immersion control, the first lifting mechanism 3 and the second lifting mechanism 4 both include a bidirectional screw rod 31 rotatably connected to the bottom of the inner cavity of the immersion pool 1, and the interior of the bidirectional screw rod 31 is a hollow structure, the outer wall of the bidirectional screw rod 31 is threadedly connected with an internal threaded sleeve 32, and the top of the internal threaded sleeve 32 is connected to the cover plate 2, the inner cavity of the bidirectional screw rod 31 is slidably connected with a sliding rod 33, and the outer wall of the sliding rod 33 is provided with a limiting strip 34, and the inner wall of the bidirectional screw rod 31 is provided with a limiting groove, the top of the sliding rod 33 is fixedly connected with a driving rod 35, and the top of the driving rod 35 passes through the inner cavity of the cover plate 2 and is rotatably connected to the cover plate 2 through a bearing, the power component 61 is connected to the driving rod 35, and the four driving rods 35 are connected by a sprocket assembly 36, wherein the power component drives one driving rod and a screw rod to rotate, and synchronously drives the other three screw rods to rotate through the chain assembly, thereby realizing smooth up and down lifting of the cover plate.

[0046] In this embodiment, the power assembly 61 includes a power box 6101, a driving motor 6102 is fixedly connected to the side wall of the power box 6101, and the top and bottom of the inner cavity of the power box 6101 are respectively rotatably connected to the first output shaft 6103 and the second output shaft 6104, the first output shaft 6103 passes through the power box 6101 and is installed with a pulley assembly 6105, and the pulley assembly 6105 is connected to a driving rod 35, the second output shaft 6104 is connected to the incomplete gear 62, the outer wall of the first output shaft 6103 is fixedly connected to the first driven bevel gear 6106 that can rotate in one direction, and the outer wall of the second output shaft 6104 is fixedly connected to the first driven bevel gear 6106 that can rotate in one direction. There are two driven bevel gears 6107, and the output end of the driving motor 6102 is fixedly connected with an active bevel gear 6108 which is meshed with the first driven bevel gear 6106 and the second driven bevel gear 6107 respectively. When the driving motor rotates in the forward direction, it can drive the first output shaft and the second output shaft to rotate synchronously, so that the cover plate can be lowered, and the placement rack can be gradually immersed in the immersion pool, and in the process of descending, the two ends of the placement rack can also slide back and forth alternately up and down. After the cover plate is installed, the driving motor rotates in the opposite direction. At this time, it can only drive the second output shaft to rotate, so that the placement rack moves, and the cover plate remains in position.

[0047] The specific working process of this embodiment is as follows:

[0048] When the bamboo is modified, a protective agent is added into the soaking tank 1 , and then the bamboo to be treated is sequentially placed on each layer of the placement rods 513 of the placement rack 51 , and then the baffles 7 on both sides of the placement rack 51 are closed.

[0049] Then the driving motor 6102 is started forward, and the driving motor 6102 drives the first driven bevel gear 6106 (and the connection structure between the first driven bevel gear 6106 and the first output shaft 6103 is: the outer wall of the first output shaft 6103 is provided with a rotating disk with a ratchet, the first driven bevel gear 6106 is sleeved on the rotating disk, and the inner hole of the first driven bevel gear 6106 is provided with a ratchet groove matched with the ratchet, and this structure enables the first output shaft 6103 to rotate in one direction) and the second driven bevel gear 6107 through the active bevel gear 6108. Rotate, wherein the first output shaft 6103 drives a driving rod 35 to rotate through the pulley assembly 6105, and synchronously drives the remaining three driving rods 35 to rotate through the sprocket assembly 36, so that the four bidirectional screw rods 31 rotate synchronously, and drive the four internal threaded sleeves 32 and the cover plate 2 to descend. During the process of the cover plate 2 descending, the driving rod 35 and the sliding rod 33 can be driven to slide inside the bidirectional screw rod 31, so as to realize the continuous rotation of the bidirectional screw rod 31, until the cover plate 2 completely covers the immersion tank 1 (the sealing strip 21 is completely inserted into the sealing groove 11);

[0050] The second output shaft 6104 rotates forward to drive the incomplete gear 62 to rotate, and the incomplete gear 62 meshes with the two first racks 64 in turn, thereby driving the rectangular frame 63 and the second rack 65 to slide back and forth. When the second rack 65 slides back and forth, it can drive the rotating gear 68 on the first double-headed screw 66 to rotate forward and drive the rotating gear 68 on the second double-headed screw 67 to rotate in the opposite direction, so that the first double-headed screw 66 and the second double-headed screw 67 rotate in opposite directions. When the first double-headed screw 66 rotates forward, it drives the two The first slider 69 slides in a direction approaching each other, thereby driving the two first sliding bars 52 to slide upward along the internal threaded sleeve 32. At the same time, the second double-headed screw 67 rotates in the opposite direction, driving the two second sliders 610 to slide in a direction away from each other, thereby driving the two second sliding bars 53 to slide downward along the internal threaded sleeve 32, and finally the placement rack 51 can be tilted, so that the bamboo and wood slide a certain distance in the tilted direction and are blocked by the baffle 7. In this way, as the rectangular frame 63 slides back and forth, the bamboo and wood slide back and forth in the placement rack 51;

[0051] After the cover plate 2 completely covers the soaking pool 1, the drive motor 6102 is started in reverse, wherein the active bevel gear 6108 drives the first driven bevel gear 6106 to idle (that is, the first output shaft 6103 does not rotate), while the second driven bevel gear 6107 and the incomplete gear 62 rotate normally, so that during the soaking process, the sealing of the soaking pool 1 can be ensured, and the bamboo can be driven to slide back and forth on the placement rack 51, so that the soaking has no dead angle and is more uniform.

[0052] During the soaking process, the external pressure pump is started to pressurize the soaking pool 1 through the pressure pipe 9 to improve the penetration efficiency, and the disc heating pipe 10 is turned on to heat and keep the protective agent warm.

[0053] After the soaking is completed, the drive motor 6102 is started in the forward direction, so that the internal threaded sleeve 32 slides upward under the drive of the bidirectional screw 31, driving the cover plate 2 and the placement rack 51 to rise. During the rising process, the bamboo and wood also slide back and forth, and can also be tilted, so that the protective agent remaining on the bamboo and wood can flow out along the inclined angle, and after rising into place, the placement rack 51 is kept in a tilted state. After the protective agent has completely flowed out, the baffle 7 at the lower end is opened, the bamboo and wood are taken out, and the bamboo and wood modification is completed.

[0054] The second embodiment of the present invention is:

[0055] A method for synergistically modifying bamboo and wood for mildew and corrosion resistance comprises the following steps:

[0056] S1. Dry the fresh raw bamboo wood in the shade to a moisture content of 12-15%. The control range of the moisture content of the raw bamboo has a significant impact on the antiseptic effect. The moisture content directly affects the penetration effect of the protective agent. If the moisture content exceeds 15%, the penetration effect is poor. If the moisture content is less than 12%, the raw bamboo is prone to cracking after and during treatment. When the moisture content is between 12% and 15%, the vacuum degree is above 0.08MPa, the treatment is carried out for 35-50min, and combined with the subsequent pressurization, the penetration effect achieved by the protective agent is better.

[0057] S2, put the dried raw bamboo wood into the placement rack 51 of the first embodiment in sequence, then cover the cover plate 2 and control the vacuum degree in the soaking tank 1 to be above 0.08MPa, and treat for 35-50min, and before S2, perform high pressure pre-treatment on the raw bamboo, and the conditions of the high pressure pre-treatment are pressure 2.6-3.2MPa, temperature 10-15℃, and treatment time 2-5min. The early high pressure pre-treatment has a short treatment time, which is controlled at 2-5 minutes, which is conducive to improving the penetration of the protective agent in the later stage;

[0058] S3, adding a protective agent into the soaking pool 1, and turning on the disc heating tube 10, and the protective agent includes the following components in parts by weight: 3-6 parts of alcohol, 3-5 parts of chitosan (and chitosan is chitosan with a deacetylation degree of 88-92%), 2-4 parts of nano titanium dioxide, 22-30 parts of acetic acid, 5-8 parts of quaternary ammonium salt, and 12-18 parts of bamboo leaf extract. The protective agent has a higher affinity with the original bamboo. Under the process adopted by the present invention, it is easier to penetrate into the interior of the original bamboo, and has good binding force with bamboo fiber, especially chitosan. Under the action of acetic acid, chitosan is more likely to carry anti-corrosion and anti-mildew effective ingredients into the bamboo fiber, and the combination is firm, and the anti-corrosion and anti-mildew effect is more lasting. In addition, chitosan and nano titanium dioxide work together to be able to more quickly and efficiently penetrate the original bamboo inner circle with the highest nutrient content and the lowest density and penetrate into the interior of the original bamboo;

[0059] In this embodiment, the bamboo leaf extract is obtained according to the following steps: A. Wash the bamboo leaves, dry them, and grind them to obtain bamboo leaf powder; B. Add an alcohol solution with a volume 2-4 times that of the bamboo leaf powder, and ultrasonically treat it for 35-50 minutes to obtain an initial extraction solution; C. Filter the initial extraction solution to obtain a bamboo leaf extract.

[0060] S4. Turn off the vacuum pump and turn on the pressure pump to make the pressure reach 1.2-1.8MPa, and maintain the pressure for dynamic immersion treatment for 50-70min;

[0061] S5, release the pressure, discharge the protective agent, and after the protective agent is discharged, first steam the bamboo and then perform vacuum treatment, wherein the steaming treatment is carried out for 30-40 minutes at a humidity of 75-88% and a temperature of 85-100°C. Adding the steaming treatment can prolong the residence time of the protective agent in the original bamboo, making it difficult to be lost, and can achieve a long-term protective effect.

[0062] In the present invention, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0063] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
