Description

Technical Field

[0001] This utility model relates to the technical field of tobacco leaf drying equipment, specifically to a cigar tobacco leaf drying shed. Background Technology

[0002] Fresh cigar tobacco leaves, harvested from the field, need to be promptly transported to drying rooms for processing. Before drying, the leaves undergo three stages: sorting, weaving, and loading (placing on drying racks). The weaving stage is done manually, and the quality of the weaving is crucial for producing high-quality cigar tobacco. Traditionally, there are two main methods for processing fresh cigar tobacco leaves: The first is needle-threading and hanging: The harvested leaves are threaded through a needle, passing the needle and thread 1.5-2 cm from the base of the leaf's main vein. Two leaves are hung back-to-back, about 2 cm apart, on a 2-meter bamboo (or wooden) pole. The second method is binding the leaves to a pole: Fresh cigar tobacco leaves are tied to a 2-meter bamboo (or wooden) pole with rope, typically one leaf per pole. If two leaves are tied together (one from the base and one from the top), they should be back-to-back. Of course, some methods involve hanging the lower tobacco leaves on poles to dry using the two methods mentioned above, while directly harvesting the middle and upper tobacco leaves by cutting the stems. The tobacco plants are then hung on 0.9m bamboo or wooden poles. All of these methods—using needle and thread to thread the tobacco leaves or tying them to the poles with rope, or cutting the stems and hanging them to dry—are laborious, time-consuming, and inefficient.

[0003] Existing technology discloses a patent with publication number CN221128222U, which includes: a pair of biomass burners arranged on both sides of a drying chamber; a flue housed in a pit within the drying chamber; a dry-bulb temperature sensor; a cold air damper; a control module; a display; a humidifier; a feeding auger; and a feeding auger motor. The combustion chamber of the biomass burner is connected to the air inlet at one end of the flue. A pipe connecting the flue and the biomass burner is installed. The dry-bulb temperature sensor and humidifier are housed within the drying chamber. The cold air damper is located on the lower side wall of the drying chamber. The display is located on the outer wall of the drying chamber. The combustion chamber is connected to the feeding auger pipe. The feeding auger is driven by a feeding auger motor. By installing a humidifier within the drying chamber and electrically connecting the control module to the humidifier, the biomass burner feed motor, the heating pipe valve of the drying chamber, and the temperature and humidity sensor within the drying chamber, the temperature and humidity within the drying chamber are effectively maintained to meet the requirements for cigar drying, thus effectively improving the quality of the dried cigars.

[0004] The shortcomings of existing technology have gradually become apparent with use, mainly in the following aspects:

[0005] First, the existing cigar drying racks have complex structures and low stability, making it difficult to adjust the height and spacing of the drying rods.

[0006] Secondly, the existing drying sheds are limited by the ventilation structure, making it difficult to adjust the size of the ventilation holes. In rainy weather, rainwater can easily enter the drying shed through the ventilation holes, affecting the stability of cigar drying.

[0007] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a cigar tobacco drying shed, which solves the problems of complex and unstable drying racks in existing cigar tobacco drying sheds, making it difficult to adjust the height and spacing of the drying rods; and the fact that existing drying sheds are limited by the ventilation structure, making it difficult to adjust the size of the ventilation holes, and that rainwater can easily enter the drying shed through the ventilation holes during rainy days, affecting the stability of cigar drying.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A cigar tobacco drying shed includes an arched shed body. Roller film retractors are vertically mounted on both side walls of the shed body. A ventilation duct is horizontally fixed to the top of the shed body along its length. An air outlet is axially positioned at the top of the ventilation duct, and an air inlet is axially positioned at the bottom of the ventilation duct. A valve plate is rotatably mounted inside the ventilation duct to adjust the size of the air inlet opening.

[0011] A shield is fixed to the top of the ventilation duct, located above the air outlet.

[0012] The shed has several movable drying racks arranged side by side. Each drying rack has several height-adjustable support rods arranged horizontally from top to bottom. Each support rod has several adjustable support seats that slide along the horizontal direction.

[0013] As an optimized solution, the drying rack includes a rectangular frame, with sliding seats slidably fitted on each of the four vertical sides of the frame corresponding to each of the support rods, and the two ends of the support rods being fixed to the opposite sidewalls of the two sliding seats in the width direction.

[0014] As an optimized solution, a vertical positioning knob is threaded onto the sliding seat, and the end of the vertical positioning knob abuts against the vertical edge of the frame.

[0015] As an optimized solution, the vertical edge of the frame is provided with several positioning slots arranged in parallel along the vertical direction, and the end of the vertical positioning knob abuts against one of the positioning slots.

[0016] As an optimized solution, each of the support bases has a U-shaped card holder fixedly connected to its upper end.

[0017] As an optimized solution, a lateral positioning knob is threaded onto the support base, and the end of the lateral positioning knob abuts against the side wall of the support rod.

[0018] As an optimized solution, a rectangular guide groove is horizontally formed on the side wall of the support rod, and the end of the horizontal positioning knob abuts against the rectangular guide groove.

[0019] As an optimized solution, the frame is equipped with omnidirectional casters at the lower ends near the four corners.

[0020] As an optimized solution, the shield is arc-shaped and has side baffles fixed to both ends along its length. The ventilation duct has several vertical rods fixed in parallel along its length on both sides of the air outlet, and the upper ends of the vertical rods are fixed to the inner top surface of the shield.

[0021] As an optimized solution, the valve plate is an arc-shaped plate that matches the inner wall of the ventilation duct. Support rings that are rotatably installed in the two ends of the arc-shaped plate are fixed to the two ends of the ventilation duct. A plug plate located on the outside of the ventilation duct is fixed to the outer end of the support ring.

[0022] As an optimized solution, a drive motor is fixedly connected to the outer wall of the ventilation duct, and a gear ring segment is fixedly connected to the outer peripheral wall of the plug plate. The output shaft of the drive motor meshes with the gear ring segment through a gear.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] The size of the openings on the sides of the greenhouse and the ventilation ducts on the top are adjusted by the lifting film rollers on both sides of the greenhouse to ventilate the inside of the greenhouse. The size of the air inlet is controlled by the rotation of the valve plate, which, together with the size of the side openings, allows for convenient and quick adjustment of the ventilation volume. In addition, a shield is installed above the air outlet of the ventilation duct to prevent rainwater from entering the air outlet on rainy days, effectively preventing rainwater from entering the inside of the greenhouse.

[0025] The drying rack uses several support rods that move vertically. By loosening the vertical positioning knob, the vertical positioning knob separates from the positioning groove, and the height of the support rods can be adjusted using the sliding seat. By loosening the horizontal positioning knob, the spacing between adjacent support seats can be adjusted. By setting up the brackets, the two ends of the cigar drying rods can be suspended on two opposite brackets, enabling quick positioning of the drying rods. This allows for adjustment of the height and spacing of the drying rods to meet the needs of drying cigars of different lengths and spacings. Attached Figure Description

Detailed Implementation

[0032] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0033] like Figures 1 to 4 As shown, the structure includes an arched canopy 1. Roller film retractors 2 are vertically mounted on both side walls of the canopy 1. A ventilation duct 4 is horizontally fixed to the top of the canopy 1 along its length. An air outlet 6 is axially opened at the top of the ventilation duct 4, and an air inlet 5 is axially opened at the bottom of the ventilation duct 4. A valve plate 9 is rotatably mounted inside the ventilation duct 4 to adjust the size of the air inlet 5.

[0034] A shield 7 is fixed to the top of the ventilation duct 4, located above the air outlet 6.

[0035] Inside the shed 1, several movable drying racks 3 are arranged side by side. The drying racks 3 are horizontally arranged from top to bottom with several height-adjustable support rods 18. Each support rod 18 is slidably provided with several adjustable support seats 20 along the horizontal direction.

[0036] The drying rack 3 includes a rectangular frame 14. Sliding seats 15 are slidably fitted on the four vertical sides of the frame 14 corresponding to each support rod 18. The two ends of the support rod 18 are fixed to the opposite side walls of the two sliding seats 15 in the width direction.

[0037] A vertical positioning knob 16 is threaded onto the sliding seat 15, and the end of the vertical positioning knob 16 abuts against the vertical edge of the frame 14.

[0038] The vertical edge of the frame 14 has several positioning grooves 17 arranged in parallel along the vertical direction, and the end of the vertical positioning knob 16 abuts against one of the positioning grooves 17.

[0039] Each support 20 has a U-shaped card holder 22 fixedly connected to its upper end.

[0040] A transverse positioning knob 21 is threaded onto the support base 20, and the end of the transverse positioning knob 21 abuts against the side wall of the support rod 18.

[0041] A rectangular guide groove 19 is horizontally provided on the side wall of the support rod 18. The end of the horizontal positioning knob 21 abuts against the rectangular guide groove 19 to guide the support seat 20 and prevent the support seat 20 from rotating around the support rod 18.

[0042] The frame 14 is equipped with omnidirectional casters 23 at the lower ends near the four corners.

[0043] The shield 7 is arc-shaped and has side baffles fixed to both ends along its length. The ventilation duct 4 has several vertical rods 8 fixed in parallel along its length on both sides of the air outlet 6. The upper ends of the vertical rods 8 are fixed to the inner top surface of the shield 7.

[0044] The valve plate 9 is an arc-shaped plate that matches the inner wall of the ventilation duct 4. Support rings 10 are fixedly connected to both ends of the arc-shaped plate and are rotatably installed in the two ports of the ventilation duct 4. A plug plate 11 located on the outside of the ventilation duct 4 is fixedly connected to the outer end of the support ring 10.

[0045] A drive motor 12 is fixedly connected to the outer wall of the ventilation duct 4, and a gear ring section 13 is fixedly connected to the outer peripheral wall of the plug 11. The output shaft of the drive motor 12 meshes with the gear ring section 13 through a gear.

[0046] A stepper motor or a servo motor can be connected to the drive motor 12, so that the controller can send pulse signals to control the number of rotation steps of the stepper motor or servo motor, thereby precisely controlling the rotation angle (each pulse corresponds to a fixed angle increment), and thus adjusting the rotation angle of the valve plate 9 to control the size of the air inlet 5.

[0047] The film rolling device 2, the structure of the shed 1, and the cigar drying facilities inside the shed 1 are all well-known in the field, so they will not be described in detail here.

[0048] The working principle of this device is as follows:

[0049] The lifting film rollers 2 on both sides of the shed 1 are used to adjust the size of the opening on the side of the shed 1 and the ventilation duct 4 on the top to ventilate the inside of the shed 1. The size of the air inlet 5 is controlled by the rotation of the valve plate 9. In combination with the size of the side opening, the ventilation volume can be adjusted conveniently and quickly. A shield 7 is installed above the air outlet 6 of the ventilation duct 4 to prevent rainwater from entering the air outlet 6 on rainy days, effectively preventing rainwater from entering the inside of the shed 1.

[0050] The drying rack 3 raises and lowers several support rods 18 vertically. By loosening the vertical positioning knob 16, the vertical positioning knob 16 separates from the positioning groove 17. The height of the support rods 18 can be adjusted using the sliding seat 15. By loosening the horizontal positioning knob 21, the distance between adjacent support seats 20 can be adjusted. By setting the card holder 22, the two ends of the cigar drying rod can be suspended on two opposite card holders 22, realizing quick positioning of the drying rod. This allows for adjustment of the height and distance of the drying rod, meeting the needs of drying cigars of different lengths and distances.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
