Abstract

The present invention belongs to the technical field of wood fumigation, and in particular relates to a continuous fumigation and conveying device for exported wood, which includes a fumigation chamber and a fumigation device fixedly arranged on the top of the fumigation chamber. A sheet material loading conveyor table and a sheet material unloading conveyor table are respectively arranged at the feeding end and the discharging end of the fumigation chamber. The fumigation conveying mechanism can rotate and convey the sheet material into the fumigation chamber for fumigation. While the fumigation conveying mechanism rotates and conveys the sheet material, the sheet material storage mechanism on the fumigation conveying mechanism can drive the sheet material storage pallet on the sheet material storage mechanism to rotate through the linkage gear on it and the linkage rack on the inner wall of the fumigation chamber, and further drive the sheet material on the sheet material storage pallet to rotate, so that the sheet material can rotate while revolving for conveying, enabling the sheet material to be fumigated evenly. Moreover, when the sheet material rotates, it can disturb the steam in the inner cavity of the fumigation chamber, which can further improve the fumigation effect.

Description

Technical Field

[0001] The present invention belongs to the technical field of wood fumigation, and particularly relates to a continuous fumigation and conveying device for exported wood. Background Art

[0002] Wood fumigation is a compulsory measure taken to prevent harmful pests in imported wood from damaging the forest resources of the importing country. Since small organisms are likely to be mixed in untreated wood, if the wood is not fumigated, it is very likely to carry pests into other countries, which is likely to cause the invasion of disease-carrying pest species and cause great losses to the target country. Therefore, wood passing in and out of the country must be fumigated.

[0003] When fumigating wood in the prior art, the wood is often stacked in a closed space, and then the stacked wood is fumigated as a whole. It is impossible to fumigate the wood continuously. Moreover, during the fumigation process, the distance between adjacent woods is too close, and the position of the wood is fixed during fumigation, which is likely to cause uneven fumigation, resulting in incomplete fumigation of the wood and poor fumigation effect.

[0004] To solve the above problems, a continuous fumigation and conveying device for exported wood is proposed in this application. Summary of the Invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. By setting up a plate feeding and conveying platform, the plates that need to be fumigated can be automatically fed and fed. The plates transported on the plate feeding and conveying platform can be automatically positioned by the plate positioning mechanism. When the plates are transported to the feeding end of the fumigation box, the plate positioning mechanism can block and position the plates through the positioning plates thereon. At this time, the positioning plates will synchronously press the induction switch under the push of the plates. At this time, the induction switch will control the plate feeding and conveying platform to stop conveying the plates. The plates that need to be fumigated can be accurately positioned to facilitate subsequent feeding.

[0020] 2. By setting up an automatic plate feeding mechanism, the automatic plate feeding mechanism can automatically push the plates that need to be fumigated into the plate storage mechanism to complete automatic feeding, and in the process of the automatic plate feeding mechanism pushing the plates for feeding, the plate clamping mechanism on the plate storage mechanism can be linked to lift up. When the automatic plate feeding mechanism is pulled out of the plate storage mechanism for reset after pushing the feeding, the plate clamping mechanism on the plate storage mechanism will be reset synchronously, and the plates can be automatically clamped and positioned, which can prevent the plates from shaking or falling from the plate storage mechanism during fumigation.

[0021] 3. By setting up a fumigation conveying mechanism, the fumigation conveying mechanism can rotate and convey the plate into the fumigation box for fumigation. While the fumigation conveying mechanism rotates and conveys the plate, the plate storage mechanism on the fumigation conveying mechanism can drive the plate storage tray on the plate storage mechanism to rotate through the linkage gear thereon and the linkage tooth plate on the inner wall of the fumigation box, and then drive the plate on the plate storage tray to rotate, so that the plate can be transported while rotating, so that the plate can be fumigated evenly, and when the plate rotates, it can disturb the steam in the inner cavity of the fumigation box, which can further improve the fumigation effect.

[0022] 4. When the fumigated board is conveyed to the discharge port of the fumigation box by the fumigation conveying mechanism, control the second electric telescopic rod on the automatic board blanking mechanism to contract. When the second electric telescopic rod contracts, it can drive the linkage plate B of the clamping mechanism to move towards the side close to the fumigation box through the connecting plate B and the pull rod B, and can link and lift the board clamping mechanism on the board storage mechanism, so that the board clamping mechanism stops clamping and fixing the board. When the linkage plate B of the clamping mechanism moves towards the direction close to the fumigation box to a certain extent, the one-way clamping mechanism at the bottom of one end of the linkage plate B of the clamping mechanism will rotate and reset under the action of its own structure, and can hook the board. At this time, control the second electric telescopic rod to extend, and the board in the board storage mechanism can be pulled out and conveyed to the board blanking conveying table through the one-way clamping mechanism, and the blanking of the board can be automatically completed, and the continuous fumigation of the board can be carried out.

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] Embodiment, as Figures 1-9As shown in the figure, a continuous fumigation and conveying device for exported wood includes a fumigation box 1 and a fumigation device 2 fixedly arranged on the top of the fumigation box 1. A board loading and conveying table 3 and a board unloading and conveying table 4 are respectively arranged at the feeding end and the discharging end of the fumigation box 1. A board automatic loading mechanism 5 and a board positioning mechanism 6 are fixedly arranged on the board loading and conveying table 3. The board to be fumigated can be automatically conveyed and loaded through the board loading and conveying table 3, and the board conveyed on the board loading and conveying table 3 can be automatically positioned through the board positioning mechanism 6. A board automatic unloading mechanism 7 is fixedly arranged on the board unloading and conveying table 4. A fumigation conveying mechanism 8 and a linkage tooth plate 9 are fixedly arranged on the fumigation box 1. Board storage mechanisms 10 are fixedly arranged at equal intervals on the fumigation conveying mechanism 8;

[0045] The board storage mechanism 10 includes a connecting piece 1001 fixedly arranged on the fumigation conveying mechanism 8, a board storage pallet 1002 rotatably installed between two groups of connecting pieces 1001, and a ventilation notch 1003 opened on the board storage pallet 1002. Linkage gears 1004 are fixedly connected to both ends of the board storage pallet 1002 through shaft rods. Board clamping mechanisms 1005 are symmetrically and fixedly arranged on the top of the board storage pallet 1002. The board to be fumigated can be automatically pushed into the board storage mechanism 10 by the board automatic loading mechanism 5 to complete automatic loading. During the process of the board automatic loading mechanism 5 pushing the board for loading, the board clamping mechanisms 1005 on the board storage mechanism 10 can be driven to lift synchronously. After the board automatic loading mechanism 5 is withdrawn from the board storage mechanism 10 and reset after the loading is completed, the board clamping mechanisms 1005 on the board storage mechanism 10 will be reset synchronously, and the board can be automatically clamped and positioned, which can avoid the board shaking or falling from the board storage mechanism 10 during fumigation. After the board is clamped and positioned by the board clamping mechanisms 1005 on the board storage mechanism 10, the board is rotated and conveyed into the fumigation box 1 by the fumigation conveying mechanism 8 for fumigation. While the fumigation conveying mechanism 8 rotates and conveys the board, the board storage mechanism 10 on the fumigation conveying mechanism 8 can drive the board storage pallet 1002 on the board storage mechanism 10 to rotate through the cooperation of the linkage gear 1004 thereon and the linkage tooth plate 9 on the inner wall of the fumigation box 1, so as to drive the board on the board storage pallet 1002 to rotate, enabling the board to rotate while revolving for conveying, so that the board can be fumigated evenly. Moreover, when the board rotates, the steam in the inner cavity of the fumigation box 1 can be disturbed, which can further improve the fumigation effect;

[0046] The sheet clamping mechanism 1005 includes a frame 10051 fixedly arranged on the top of the sheet storage pallet 1002. A pin rod 10052 is slidably inserted through the frame 10051. A clamping plate member 10053 and a return spring 10054 are respectively arranged at the bottom end and the outer side of the pin rod 10052. A linkage notch 10055 is formed on the clamping plate member 10053. An extrusion slope 10056 is arranged at the top of the inner cavity of the linkage notch 10055. A clamping block 10057 is fixedly arranged at the bottom of one side of the clamping plate member 10053. During the process of the sheet automatic feeding mechanism 5 pushing the sheet for feeding, one end of the clamping mechanism linkage plate A507 on the sheet automatic feeding mechanism 5 is inserted into the linkage notch 10055 on the clamping plate member 10053. The extrusion slope 10056 in the linkage notch 10055 can be used to link and lift the sheet clamping mechanism 1005 on the sheet storage mechanism 10. When the feeding of the sheet by the sheet automatic feeding mechanism 5 is completed and one end of the clamping mechanism linkage plate A507 on the sheet automatic feeding mechanism 5 is withdrawn from the linkage notch 10055 for resetting, the clamping plate member 10053 and the clamping block 10057 on the sheet clamping mechanism 1005 will be reset synchronously under the elastic force of the return spring 10054. The reset clamping plate member 10053 can clamp and fix the sheet, and the reset clamping block 10057 can block and position both ends of the sheet, which can prevent the sheet from shaking or falling off the sheet storage mechanism 10 during fumigation.

[0047] As a further embodiment of the above invention: The linkage gear 1004 is meshed and connected with the linkage tooth plate 9. The sheet storage mechanism 10 on the fumigation conveying mechanism 8 can drive the sheet storage pallet 1002 on the sheet storage mechanism 10 to rotate through the cooperation of the linkage gear 1004 thereon and the linkage tooth plate 9 on the inner wall of the fumigation chamber 1, and further drive the sheet on the sheet storage pallet 1002 to rotate, so that the sheet can rotate while revolving for conveying.

[0048] As a further embodiment of the above invention: The automatic sheet feeding mechanism 5 includes a first electric telescopic rod 501 fixedly installed at the bottom of the sheet feeding conveyor table 3 and a first guide plate 502 fixedly arranged on the top of the sheet feeding conveyor table 3. One end of the first electric telescopic rod 501 is fixedly connected with a connecting plate member A503. One side of the connecting plate member A503 is fixedly provided with a pull rod A504, and one end of the pull rod A504 penetrates through the first guide plate 502. The end of the pull rod A504 penetrating through the first guide plate 502 is fixedly provided with a push plate 505. The push plate 505 is fixedly provided with a push rod member 506 and a clamping mechanism linkage plate A507. When the first electric telescopic rod 501 on the automatic sheet feeding mechanism 5 contracts, the first electric telescopic rod 501 can push the sheet on the sheet feeding conveyor table 3 into the sheet storage mechanism 10 for automatic feeding through the connecting plate member A503, the pull rod A504, the push plate 505 and the push rod member 506. During the process of pushing the sheet for feeding, one end of the clamping mechanism linkage plate A507 on the automatic sheet feeding mechanism 5 is inserted into the linkage notch 10055 on the clamping plate member 10053, and the extrusion slope 10056 in the linkage notch 10055 can be used to link and lift the sheet clamping mechanism 1005 on the sheet storage mechanism 10.

[0049] As a further embodiment of the above invention: The sheet positioning mechanism 6 includes sliding grooves 601 symmetrically opened on the top of the sheet feeding conveyor table 3 and a connecting support column 602 fixedly arranged at one end of the top of the sheet feeding conveyor table 3. One side of the inner cavity of the sliding groove 601 is fixedly provided with a spring member 603. One end of the spring member 603 is fixedly connected with a slider 604. The top of the slider 604 is fixedly provided with a positioning plate member 605. One end of the connecting support column 602 is fixedly provided with an induction switch 606. When the sheet is conveyed to the feeding end of the fumigation chamber 1, the sheet positioning mechanism 6 can block and position the sheet through the positioning plate member 605 thereon. At this time, the positioning plate member 605 will synchronously press the induction switch 606 under the push of the sheet. At this time, the induction switch 606 will control the sheet feeding conveyor table 3 to stop conveying the sheet. At this time, the sheet is located at the feeding end of the fumigation chamber 1, and the sheet to be fumigated can be accurately positioned, which is convenient for subsequent feeding. After the sheet to be fumigated is automatically pushed into the sheet storage mechanism by the automatic sheet feeding mechanism 5 to complete automatic feeding, the positioning plate member 605 automatically separates from the induction switch 606 under the action of the spring member 603. At this time, the sheet feeding conveyor table 3 continues to rotate to convey the next group of sheets.

[0050] As a further embodiment of the above invention: The slider 604 matches the sliding groove 601, and the slider 604 is slidably installed inside the sliding groove 601. The slider 604 being slidably installed in the sliding groove 601 enables the positioning plate member 605 to slide smoothly, which is convenient for linking and pressing the induction switch 606 or resetting under the action of the spring member 603.

[0051] As a further embodiment of the above invention: The automatic sheet material blanking mechanism 7 includes a second electric telescopic rod 701 fixedly installed at the bottom of the sheet material blanking conveyor table 4 and a second guide plate 702 fixedly arranged on the top of the sheet material blanking conveyor table 4. One end of the second electric telescopic rod 701 is fixedly connected with a connecting plate member B703. A pull rod B704 is fixedly arranged on one side of the connecting plate member B703, and one end of the pull rod B704 penetrates through the second guide plate 702. A pull plate 705 is fixedly arranged at the end of the pull rod B704 penetrating through the second guide plate 702. A clamping mechanism linkage plate B706 is fixedly arranged on the pull plate 705. A one-way clamping mechanism 707 is arranged at the bottom of one end of the clamping mechanism linkage plate B706.

[0052] As a further embodiment of the above invention: The one-way clamping mechanism 707 includes a rectangular installation groove 7071 opened at the bottom of one end of the clamping mechanism linkage plate B706. A connecting column 7072 is fixedly arranged in the inner cavity of the rectangular installation groove 7071. A clamping member 7073 is sleeved outside the connecting column 7072. A torsion spring 7074 is fixedly arranged between the clamping member 7073 and the connecting column 7072. When the fumigated sheet material is conveyed to the discharge port of the fumigation box 1 by the fumigation conveyor mechanism 8, the second electric telescopic rod 701 on the automatic sheet material blanking mechanism 7 is controlled to contract. When the second electric telescopic rod 701 contracts, the clamping mechanism linkage plate B706 can be driven to move towards the side close to the fumigation box 1 through the connecting plate member B703 and the pull rod B704. One end of the clamping mechanism linkage plate B706 is inserted into the linkage notch 10055 on the clamping plate member 10053. The extrusion slope 10056 in the linkage notch 10055 can be used to drive the sheet material clamping mechanism 1005 on the sheet material storage mechanism 10 to be lifted. At this time, the clamping plate member 10053 and the clamping block 10057 on the sheet material clamping mechanism 1005 stop clamping and fixing the sheet material. When the clamping mechanism linkage plate B706 moves towards the direction close to the fumigation box 1 to a certain extent, the one-way clamping mechanism 707 at the bottom of one end of the clamping mechanism linkage plate B706 will rotate and reset under the elastic action of its own torsion spring 7074. After the rotation and reset, the one-way clamping mechanism 707 can hook the sheet material through the clamping member 7073. At this time, the second electric telescopic rod 701 is controlled to extend, and the sheet material in the sheet material storage mechanism 10 can be pulled out and conveyed onto the sheet material blanking conveyor table 4 through the one-way clamping mechanism 707, and the blanking of the sheet material can be automatically completed, and continuous fumigation of the sheet material can be carried out.

[0053] As a further embodiment of the above invention: Arc-shaped guiding slopes are arranged at the ends of the clamping mechanism linkage plate A507 and the clamping mechanism linkage plate B706. The arrangement of the arc-shaped guiding slopes makes it more convenient for the clamping mechanism linkage plate A507 and the clamping mechanism linkage plate B706 to be inserted into the linkage notch 10055 to lift the sheet material clamping mechanism 1005.

[0054] As a further embodiment of the above invention: when the sheet storage mechanism 10 moves to the feeding end of the fumigation chamber 1 and when it moves to the discharging end of the fumigation chamber 1, the sheet storage pallets 1002 on the sheet storage mechanism 10 are both in a horizontal state, and the sheet clamping mechanism 1005 is vertically upward, facilitating the feeding and discharging of the sheets by the automatic sheet loading mechanism 5 and the automatic sheet unloading mechanism 7.

[0055] As a further embodiment of the above invention: the fumigation conveying mechanism 8 includes an extension plate A801 and an extension plate B802 symmetrically and fixedly arranged at both ends of the fumigation chamber 1. A driving motor 803 is fixedly arranged outside the extension plate B802. The end of the output shaft of the driving motor 803 is fixedly connected with a driving roller A804. A driving roller B805 is rotatably arranged between the two extension plates A801. A conveyor belt 806 is connected between the driving roller B805 and the driving roller A804. The sheet storage mechanisms 10 are equidistantly and fixedly arranged on the conveyor belt 806. The driving motor 803 can drive the conveyor belt 806 to rotate through the driving roller A804. When the conveyor belt 806 rotates, the sheets can be rotationally conveyed into the fumigation chamber 1 for fumigation.

[0056] During specific implementation: the automatic feeding of the sheets to be fumigated can be carried out through the sheet feeding and conveying table 3. When the sheets are conveyed to the feeding end of the fumigation chamber 1, the sheet positioning mechanism 6 can block and position the sheets through the positioning plate member 605 thereon. At this time, the positioning plate member 605 will simultaneously press the induction switch 606 under the push of the sheets. At this time, the induction switch 606 will control the sheet feeding and conveying table 3 to stop conveying the sheets. At this time, the sheets are located at the feeding end of the fumigation chamber 1, and the sheets to be fumigated can be accurately positioned, facilitating subsequent feeding. After the sheets to be fumigated are automatically pushed into the sheet storage mechanism by the automatic sheet loading mechanism 5 to complete automatic feeding, the positioning plate member 605 automatically separates from the induction switch 606 under the action of the spring member 603. At this time, the sheet feeding and conveying table 3 continues to rotate to convey the next group of sheets;

[0057] The automatic sheet feeding mechanism 5 can automatically push the sheet positioned by the sheet positioning mechanism 6 into the sheet storage mechanism 10 to complete automatic feeding. During the process of the automatic sheet feeding mechanism 5 pushing the sheet for feeding, one end of the clamping mechanism linkage plate A507 on the automatic sheet feeding mechanism 5 is inserted into the linkage slot 10055 on the clamping plate member 10053. The extrusion ramp 10056 in the linkage slot 10055 can be used to link and lift the sheet clamping mechanism 1005 on the sheet storage mechanism 10. When the sheet is pushed and fed by the automatic sheet feeding mechanism 5 and completed, after one end of the clamping mechanism linkage plate A507 on the automatic sheet feeding mechanism 5 is withdrawn from the linkage slot 10055 for reset, the clamping plate member 10053 on the sheet clamping mechanism 1005 and the clamping block 10057 will be reset synchronously under the elastic force of the reset spring 10054. The reset clamping plate member 10053 can clamp and fix the sheet, and the reset clamping block 10057 can block and position both ends of the sheet, which can prevent the sheet from shaking or falling off the sheet storage mechanism 10 during fumigation;

[0058] After the sheet clamping mechanism 1005 on the sheet storage mechanism 10 clamps and positions the sheet, continue to control the fumigation conveying mechanism 8 to rotate. The fumigation conveying mechanism 8 rotates and conveys the sheet into the fumigation chamber 1 for fumigation. While the fumigation conveying mechanism 8 rotates and conveys the sheet, the sheet storage mechanism 10 on the fumigation conveying mechanism 8 can drive the sheet storage pallet 1002 on the sheet storage mechanism 10 to rotate through the cooperation of the linkage gear 1004 on it and the linkage tooth plate 9 on the inner wall of the fumigation chamber 1. Furthermore, it can drive the sheet on the sheet storage pallet 1002 to rotate, so that the sheet can rotate while revolving for conveying, enabling the sheet to be fumigated evenly. Moreover, when the sheet rotates, it can disturb the steam in the inner cavity of the fumigation chamber 1, which can further improve the fumigation effect;

[0059] When the fumigated board is conveyed to the discharge port of the fumigation box 1 by the fumigation conveying mechanism 8, control the second electric telescopic rod 701 on the automatic board blanking mechanism 7 to contract. When the second electric telescopic rod 701 contracts, it can drive the linkage plate B706 of the clamping mechanism to move towards the side close to the fumigation box 1 through the connecting plate B703 and the pull rod B704. One end of the linkage plate B706 of the clamping mechanism is inserted into the linkage notch 10055 on the clamping plate 10053. The extrusion slope 10056 in the linkage notch 10055 can be used to link and lift the board clamping mechanism 1005 on the board storage mechanism 10. At this time, the clamping plate 10053 and the clamping block 10057 on the board clamping mechanism 1005 stop clamping and fixing the board. When the linkage plate B706 of the clamping mechanism moves towards the position close to the fumigation box 1 to a certain extent, the one-way clamping mechanism 707 at the bottom of one end of the linkage plate B706 of the clamping mechanism will rotate and reset under the elastic action of its own torsion spring 7074.
