Description

Technical Field

[0001] This utility model relates to the field of tobacco production, specifically a tobacco storage device. Background Technology

[0002] Fresh tobacco leaves need to be dried after harvesting. Utility model patent application number CN202223383305.4 discloses a tobacco leaf storage device, which uses a cover to enclose the storage space and sets up hanging rods inside the cover. This patent does not further disclose the opening and closing structure of the cover. The common door-type opening and closing structure in the prior art cannot fully open the space inside the cover, which limits the operating space during drying and makes it inconvenient. In addition, this patent uses radially distributed horizontal bars as hanging rods, and the spacing between adjacent horizontal bars increases linearly from the inner end to the outer end. This results in a high density of tobacco leaves in the inner area and a low density in the outer area, leading to uneven drying and low space utilization. Summary of the Invention

[0003] To address the problems of inconvenient hanging, low space utilization, and uneven drying in tobacco leaf storage and drying devices, this utility model provides a tobacco storage device.

[0004] The technical solution includes a drying unit and a protective unit. The drying unit includes a base with a vertical shaft mounted on it, and a drying rod fixed on the vertical shaft. The protective unit includes several cylindrical bodies with open ends, which are coaxially fitted together with the vertical shaft as the axis. From the inside out, the diameter of the cylindrical bodies increases in an arithmetic sequence. The lower end of the innermost cylindrical body is fixed to the base. Except for the innermost cylindrical body, the lower end of each of the other cylindrical bodies is provided with an inwardly extending annular edge plate with a perforated hole. The inner wall of the annular edge plate contacts the outer wall of the next innermost cylindrical body. The upper end of each cylindrical body is provided with an outwardly extending annular limiting edge, the outer diameter of which is larger than the inner diameter of the annular edge plate. The protective unit also includes a cover plate fixed to the upper end of the vertical shaft.

[0005] A protective mesh is attached to the annular edge plate.

[0006] A winch is provided on the cover plate, and a wire rope is connected between the winch and the outermost cylinder.

[0007] The aforementioned drying rack comprises multiple layers spaced apart vertically.

[0008] The drying rod is involute-shaped, and its inner end is fixed to the vertical axis.

[0009] The vertical shaft is provided with a radial reinforcing rod, which is connected and fixed to the drying rod.

[0010] The lower end of the vertical shaft is connected to a drive motor, which can drive the vertical shaft and the drying rod to rotate.

[0011] This invention achieves the sealing and opening of the protective unit through the lifting and lowering of the multi-section cylinder, facilitating the hanging of tobacco leaves; the gradually opening linear hanging rod can make more efficient use of the space inside the cylinder, hanging more tobacco leaves in the same space, and the density of tobacco leaves hanging in each place is uniform, which is conducive to synchronous air drying.

[0017] Figure 6 for Figure 4 A magnified view of position B in the middle. Detailed Implementation

[0018] Referring to the accompanying drawings, this utility model includes a drying unit and a protective unit. The drying unit includes a base 1, on which a vertical shaft 2 is mounted, and a drying rod 3 is fixed on the vertical shaft 2, on which tobacco leaves are hung. The protective unit includes several cylindrical bodies 4 with open ends, which are coaxially fitted together around the vertical shaft 2. The cylindrical bodies 4 can be lifted layer by layer to form a retractable stepped cylindrical structure. From the inside out, the diameter of the cylindrical bodies 4 increases in an arithmetic sequence. The lower end of the innermost cylindrical body 4 is fixed to the base 1. Except for the innermost cylindrical body 4, the lower end of each of the other cylindrical bodies 4 is provided with an inwardly extending annular edge plate 5, which has a perforation. The inner wall of the annular edge plate 5 contacts the outer wall of the innermost cylindrical body 4. Each cylindrical body 4 has an outwardly extending annular limiting edge 7 at its upper end. The outer diameter of the limiting edge 7 is larger than the inner diameter of the annular edge plate 5. When the cylindrical body 4 is lifted, it can prevent the outer cylindrical body 4 from slipping off the inner cylindrical body 4. The protective unit also includes a cover plate 8 fixed to the upper end of the vertical shaft 2. When the outermost cylindrical body 4 is lifted to the highest position, the upper end of the cylindrical body 4 contacts the cover plate 8. At this time, all the cylindrical bodies 4, the cover plate 8 and the base 1 form a closed cylindrical structure, which covers the inside of the drying unit and protects the unit. At the same time, ventilation can be achieved through the hollow hole 6 on the annular edge plate 5.

[0019] A protective mesh 9 is attached to the annular edge plate 5 to prevent insects and ants from entering the protective unit through the perforated holes 6, provided that ventilation is possible.

[0020] The cover plate 8 is equipped with a winch 10, and a wire rope 11 is connected between the winch 10 and the outermost cylinder 4. The cylinder 4 can be lifted by the winch 10 winding the wire rope 11 and the cooperation of the annular edge plate 5 and the limiting edge 7.

[0021] The drying rack 3 includes multiple layers spaced at intervals to increase the amount of tobacco leaves that can be dried.

[0022] The drying rod 3 is involute-shaped, and the inner end of the drying rod 3 is fixed to the vertical shaft 2. The tobacco leaves are hung on the drying rod 3 at fixed intervals, which can improve the utilization rate of the space inside the tube and make the drying density of tobacco leaves in different parts of the tube consistent.

[0023] The vertical shaft 2 is provided with a radial reinforcing rod 12, which is connected and fixed to the drying rod 3 to improve the load-bearing capacity of the drying rod 3.

[0024] The lower end of the vertical shaft 2 is connected to a drive motor 13, which can drive the vertical shaft 2 and the drying rod 3 to rotate. Adjusting the position of the drying rod 3 facilitates drying and also helps to dry the tobacco leaves evenly.

[0025] In use, the present invention first lowers the cylinder 4 using a winch 10. Under the action of gravity, each cylinder 4 is lowered onto the base 1, exposing the drying unit. At this time, the tobacco leaves can be conveniently and evenly hung on the drying rod 3. After drying, the cylinder 4 is lifted upward by the winch 10. The outermost cylinder 4 moves upward first. When the annular edge plate 5 at the lower end of the outermost cylinder 4 contacts the limiting edge 7 at the upper end of the second cylinder 4, the second cylinder 4 is pulled up synchronously. This process continues until the upper end of the outermost cylinder 4 contacts the cover plate 8, sealing and forming a complete protective unit. Ventilation is achieved through the perforated holes 6 on each annular edge plate 5.

[0026] An exhaust fan can be installed on the cover plate 8 for auxiliary ventilation, and a heating and drying unit can be installed for drying. This is existing technology and will not be described in detail here.

[0027] This utility model achieves the sealing and opening of the protective unit through the lifting and lowering of the multi-section cylinder 4, which facilitates the hanging of tobacco leaves; the gradually opening linear hanging rod 3 can make more efficient use of the space inside the cylinder, hang more tobacco leaves in the same space, and the density of tobacco leaves hanging in each place is uniform, which is conducive to synchronous air drying.
