Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] In one embodiment, such as Figures 1-4 As shown, a special drying device for flue-cured tobacco includes a drying chamber shell 100. Two heating wires 200 are symmetrically arranged on the inner wall of the drying chamber shell 100 for heating and drying the tobacco leaves. Multiple drying rods 300 are rotatably connected within the drying chamber shell 100. The rotation of the drying rods 300 drives the tobacco leaves to be dried to rotate, thereby ensuring more even heating. A sealing cover 500 is fitted on the top of the drying chamber shell 100 to prevent hot air from escaping. A gear set 600 is fitted within the sealing cover 500 to drive the rotation of the drying rods 300. A motor 400 is fixedly connected to the top of the sealing cover 500 to provide power for the rotation of the gear set 600.
[0025] In one embodiment, such as Figure 2 As shown, the drying chamber housing 100 includes an observation window mounting hole 101, a sealing cover mounting groove 102, and a drying rod mounting hole 103. The observation window mounting hole 101 is provided on the side of the drying chamber housing 100 to reserve space for mounting the window, thereby facilitating observation of the drying status of the tobacco leaves in the heating wire 200. The top of the drying chamber housing 100 is provided with a sealing cover mounting groove 102, and the bottom of the drying chamber housing 100 is provided with multiple drying rod mounting holes 103 to limit the rotation of the drying rod 300.
[0026] In one embodiment, such as Figure 3As shown, the drying rod 300 includes a drying rod shaft 301, a suspension platform 302, a hook 303, a connecting block 304, and a bottom extension block 305. Multiple suspension platforms 302 are evenly distributed on the drying rod shaft 301, and multiple hooks 303 are provided at the bottom of the suspension platform 302 for hanging tobacco leaves. The top of the drying rod shaft 301 is fixedly connected to the connecting block 304, and the bottom of the drying rod shaft 301 is provided with a bottom extension block 305 that cooperates with the drying rod mounting hole 103. The drying rod shaft 301 is rotatably connected to the drying chamber shell 100 through the bottom extension block 305.
[0027] In one embodiment, such as Figure 3 As shown, the hooks 303 are arranged in a circumferential array below the suspension platform 302, which makes the tobacco leaves more dispersed and avoids the tobacco leaves from piling up, thus affecting the drying effect.
[0028] In one embodiment, such as Figure 3 As shown, the sealing cover 500 includes an upper cover 501, a handle 502, a motor shaft mounting hole 503, a lower cover 504, a connecting post 505, and a gear shaft mounting hole 506. The upper cover 501 and the sealing cover mounting groove 102 are sized to match each other. Two handles 502 are fixedly connected to the upper cover 501, allowing the sealing cover 500 to be moved away from above the drying chamber shell 100 via the handles 502. A motor shaft mounting hole 503 is provided in the upper cover 501, which is a reserved hole for the output end of the motor 400. A lower cover 504 is also provided below the upper cover 501. Multiple connecting posts 505 are fixedly connected to the upper surface of the lower cover 504, which is connected to the upper cover 501 via the connecting posts 505. Multiple gear shaft mounting holes 506 are also distributed in a circumferential array on the lower cover 504, which are reserved holes for the gear shaft 603.
[0029] In one embodiment, such as Figure 4 As shown, the gear set 600 includes a driving gear 601, a driven gear 602, a gear shaft 603, and a transition block mounting groove 604. The output end of the motor 400 is fitted with the driving gear 601 to provide power for the rotation of the driving gear 601. Multiple driven gears 602 are fitted around the driving gear 601, so that the rotation of the driving gear 601 drives the rotation of the driven gears 602. The gear shaft 603 is fixedly connected to the driven gear 602 to limit the rotation of the driven gear 602. The gear shaft 603 has a transition block mounting groove 604.
[0030] In one embodiment, such as Figure 3As shown, the dimensions of the gear shaft 603 and the gear shaft mounting hole 506 are matched to each other, so that the driven gear 602 can rotate around the axis of the gear shaft mounting hole 506; the dimensions of the adapter block mounting groove 604 and the adapter block 304 are matched to each other, so that when the adapter block 304 is inserted into the hole of the adapter block mounting groove 604, the driven gear 602 can drive the drying rod shaft 301 to rotate synchronously.
[0031] In one embodiment, such as Figure 2 As shown, a sealing gasket 700 that matches the size of the sealing cover mounting groove 102 is also provided above the drying chamber shell 100, so that the drying chamber shell 100 and the sealing cover 500 can fit more tightly and improve the drying effect.
[0032] Working principle: First, the tobacco leaves are hung on the hooks 303 one by one. After hanging, the drying rod 300 is inserted into the drying rod mounting hole 103 through the bottom extension block 305. Then, the sealing gasket 700 is placed on the sealing cover mounting groove 102. Next, the holes of the adapter block mounting groove 604 and the adapter block 304 are aligned. The upper cover 501 is placed stably in the sealing cover mounting groove 102. The heating wire 200 and the motor 400 are started to heat and dry the tobacco leaves. At the same time, the motor 400 drives the driven gear 602 to rotate through the drive gear 601, which in turn causes the drying rod shaft 301 to rotate, so that the tobacco leaves can receive the heat source evenly, thus making the drying more thorough.
[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
