Description

Technical Field

[0001] This utility model relates to the field of tobacco fumigation technology, specifically a structure for sealing gaps in the entire fumigation chamber for tobacco leaves. Background Technology

[0002] Before being made into finished cigarettes, flue-cured tobacco is usually stored in a warehouse for a period of time, typically several years. During the storage process, the losses caused by flue-cured tobacco pests are very serious every year. In order to reduce and prevent the losses of flue-cured tobacco, the tobacco leaves need to be placed in a concentrated area inside the warehouse, and then fumigated with phosphine using a fumigation device to control and kill the pests.

[0003] Before fumigation, the tobacco needs to be covered and sealed to ensure the fumigation effect, so that the fumigation agent can fully contact the tobacco. The existing sealing method is mostly to have workers pull the sealing cloth to cover and seal the tobacco, which is labor-intensive and inconvenient. Therefore, in order to solve the above problems, a gap sealing structure for the whole warehouse of tobacco fumigation is proposed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A sealing structure for the entire warehouse gaps in tobacco fumigation, as described in this utility model, includes a fixed plate. A drive motor is fixedly connected to the outer side of the fixed plate. A first bevel gear is fixedly connected to the output end of the drive motor. A second bevel gear meshes with the outer side of the first bevel gear. A movable screw is fixedly connected to the outer side of the second bevel gear. The movable screw is rotatably connected to the fixed plate. A movable plate is threadedly connected to the outer side of the movable screw. The fixed plate and the movable plate are slidably connected. A sliding plate is rotatably connected to the outer side of the movable plate. A sealing plate is rotatably connected to the outer side of the fixed plate. A sliding opening is provided on the inner side of the sealing plate. The groove and the sliding plate are slidably connected. This step involves setting up a first bevel gear, a second bevel gear, a moving screw, a sliding plate, and a sealing plate. In use, the device is first installed on the ceiling of the tobacco warehouse. Then, the drive motor is started, which drives the first and second bevel gears to rotate. The second bevel gear drives the moving screw to rotate, which in turn drives the moving plate and the sliding plate to move. The sliding plate pulls the sealing plate to rotate until they are pressed tightly together, and one end of the sealing plate rotates to be pressed against the ground. This allows the sealing plate to form a sealed space with the ground to isolate the tobacco inside, and then fumigation can be carried out. This improves the convenience of sealing the device.

[0006] Preferably, a partition plate is fixedly connected to the outer side of the second bevel gear, and a connecting groove is formed on the surface of the partition plate. The connecting groove is rotatably connected to the moving screw. This step, by setting the partition plate and the connecting groove, restricts one end of the moving screw, making the rotation of the moving screw more stable. Furthermore, the partition plate further restricts the range of motion of the moving plate, preventing the moving plate from contacting the first bevel gear and the second bevel gear, thereby improving the stability of the device operation.

[0007] Preferably, a first sealing strip is fixedly connected to the outer side of one side of the sealing plate, and a second sealing strip is fixedly connected to the outer side of the sealing plate. This step, by setting the first sealing strip and the second sealing strip, both of which are made of elastic material, allows the sealing plates to come into contact with each other when they are close together. The first sealing strip can then adhere tightly to the other sealing plate, thereby further sealing the sealing plates. The second sealing strip, in contact with the ground, can further seal the sealing plate and the ground, thus further improving the sealing performance of the device.

[0008] Preferably, a mounting plate is fixedly connected to the outer side of the fixing plate, and a mounting groove is formed on the surface of the mounting plate. This step, by setting the mounting plate and the mounting groove, allows the device to be fixed by screwing the bolts into the mounting groove during the installation of the fixing plate, without the need for additional drilling or the use of clips, thus improving the convenience of device installation.

[0009] Preferably, a first magnetic plate is fixedly connected to the outside of the fixing plate, and a second magnetic plate is fixedly connected to the outside of the sealing plate. The first magnetic plate and the second magnetic plate work together. By setting the first magnetic plate and the second magnetic plate, when the sealing plate is raised, the first magnetic plate and the second magnetic plate can attract each other, thereby further fixing the position of the sealing plate and improving the stability of the device when it is deployed.

[0010] Preferably, a reinforcing block is fixedly connected to the outer side of one side of the sealing plate, and a reinforcing rod is slidably connected to the inner side of the other side of the sealing plate. The reinforcing block and the reinforcing rod are slidably connected. By setting the reinforcing block and the reinforcing rod, when the sealing plates are connected to each other, the reinforcing rod can be inserted into the inner side of the reinforcing block, thereby further reinforcing the connection after the sealing plates are merged and improving the stability of the device.

[0011] The advantages of this utility model are:

[0012] 1. This utility model, by setting up a first bevel gear, a second bevel gear, a moving screw, a sliding plate, and a sealing plate, allows for easy use. First, the device is installed on the ceiling of a tobacco warehouse. Then, the drive motor is started, causing the first and second bevel gears to rotate. The second bevel gear then rotates the moving screw, which in turn moves the sliding plate and the sliding plate. The sliding plate pulls the sealing plate until it rotates tightly against the ground, creating a sealed space that isolates the tobacco inside. Fumigation can then be performed, improving the convenience of sealing the device.

[0013] 2. By setting up a partition and a connecting groove, the partition and the connecting groove restrict one end of the moving screw, making the rotation of the moving screw more stable. The partition further restricts the range of motion of the moving plate, preventing the moving plate from contacting the first bevel gear and the second bevel gear, thus improving the stability of the device operation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figure 1-5 As shown, a sealing structure for the gaps in a tobacco fumigation chamber includes a fixed plate 1. A drive motor 2 is fixedly connected to the outer side of the fixed plate 1. A first bevel gear 3 is fixedly connected to the output end of the drive motor 2. A second bevel gear 4 meshes with the outer side of the first bevel gear 3. A movable screw 5 is fixedly connected to the outer side of the second bevel gear 4. The movable screw 5 is rotatably connected to the fixed plate 1. A movable plate 6 is threadedly connected to the outer side of the movable screw 5. The fixed plate 1 and the movable plate 6 are slidably connected. A sliding plate 7 is rotatably connected to the outer side of the movable plate 6. A sealing plate 8 is rotatably connected to the outer side of the fixed plate 1. A groove 9 is formed on the inner side of the sealing plate 8. The groove 9 and the sliding plate 7 slide together. The connection process involves setting up a first bevel gear 3, a second bevel gear 4, a moving screw 5, a sliding plate 7, and a sealing plate 8. In use, the device is first installed on the ceiling of the tobacco warehouse. Then, the drive motor 2 is started, which drives the first bevel gear 3 and the second bevel gear 4 to rotate. The second bevel gear 4 drives the moving screw 5 to rotate, which in turn drives the moving plate 6 and the sliding plate 7 to move. The sliding plate 7 pulls the sealing plate 8 to rotate until they are pressed tightly together, and one end of the sealing plate 8 rotates to be flush with the ground. This creates a sealed space between the sealing plate 8 and the ground, isolating the tobacco inside. Fumigation can then be performed, improving the convenience of sealing the device.

[0024] Furthermore, such as Figure 2 and Figure 3 As shown, a partition plate 19 is fixedly connected to the outer side of the second bevel gear 4. A connecting groove 10 is provided on the surface of the partition plate 19. The connecting groove 10 is rotatably connected to the moving screw 5. This step, by setting the partition plate 19 and the connecting groove 10, restricts one end of the moving screw 5 through the partition plate 19 and the connecting groove 10, making the rotation of the moving screw 5 more stable. The partition plate 19 further restricts the range of motion of the moving plate 6, so that the moving plate 6 will not contact the first bevel gear 3 and the second bevel gear 4, thereby improving the stability of the device operation.

[0025] Furthermore, such as Figure 1As shown, a first sealing strip 11 is fixedly connected to the outer side of one side of the sealing plate 8, and a second sealing strip 12 is fixedly connected to the outer side of the sealing plate 8. This step, by setting the first sealing strip 11 and the second sealing strip 12, both of which are made of elastic material, allows the first sealing strip 11 to press against the other side of the sealing plate 8 when the sealing plates 8 come into contact with each other, thereby further sealing between the sealing plates 8. The second sealing strip 12 contacts the ground, allowing it to further seal between the sealing plate 8 and the ground, thus further improving the sealing performance of the device.

[0026] Furthermore, such as Figure 1 As shown, a mounting plate 13 is fixedly connected to the outer side of the fixing plate 1. The mounting plate 13 has a mounting groove 14 on its surface. By setting the mounting plate 13 and the mounting groove 14, the device can be fixed by screwing the bolts into the mounting groove 14 when the fixing plate 1 is installed, without the need for drilling or using clips, thus improving the convenience of device installation.

[0027] Furthermore, such as Figure 1 As shown, a first magnetic plate 15 is fixedly connected to the outside of the fixing plate 1, and a second magnetic plate 16 is fixedly connected to the outside of the sealing plate 8. The first magnetic plate 15 and the second magnetic plate 16 work together. By setting the first magnetic plate 15 and the second magnetic plate 16, when the sealing plate 8 is raised, the first magnetic plate 15 and the second magnetic plate 16 can attract each other, thereby further fixing the position of the sealing plate 8 and improving the stability of the device when it is deployed.

[0028] Furthermore, such as Figure 1 As shown, a reinforcing block 17 is fixedly connected to the outer side of one side of the sealing plate 8, and a reinforcing rod 18 is slidably connected to the inner side of the sealing plate 8 on the other side. The reinforcing block 17 and the reinforcing rod 18 are slidably connected. By setting the reinforcing block 17 and the reinforcing rod 18, when the sealing plates 8 are connected to each other, the reinforcing rod 18 can be inserted into the inner side of the reinforcing block 17, thereby further reinforcing the connection of the sealing plates 8 after they are merged, and improving the stability of the device.

[0029] Working principle: When not sealed, the sealing plate 8 and the fixing plate 1 are set in parallel. In use, first install the device on the ceiling of the tobacco warehouse, then start the drive motor 2. The drive motor 2 drives the first bevel gear 3 and the second bevel gear 4 to rotate. The second bevel gear 4 drives the moving screw 5 to rotate. The moving screw 5 drives the moving plate 6 and the sliding plate 7 to move. The sliding plate 7 pulls the sealing plate 8 to rotate until they are close to each other, and one end of the sealing plate 8 rotates to be close to the ground. Thus, the sealing plate 8 and the ground form a sealed space to isolate the tobacco inside. Then, pull the reinforcing rod 18 to insert it into the inside of the reinforcing block 17, and then perform fumigation.
