Description

Technical Field

[0001] The utility model relates to the technical field of tobacco hanging racks, in particular to an adjustable hanging tobacco rack. Background Art

[0002] The tobacco leaf preparation process begins with picking the leaves from the fields. After picking, the leaves are tied into bundles and placed on hanging racks. Finally, the racks are moved to the drying room for drying. During the hanging process, the racks are over 2 meters high, and the horizontal bars on the racks are higher than the workers. Therefore, steps or ladders are placed in the racks to facilitate the hanging process. However, frequent climbing poses certain safety risks.

[0003] The existing Chinese patent (publication number: CN220236028U) discloses a mobile flue-cured tobacco hanging rack structure that is easy to disassemble, including a base, and also including: multiple groups of support components installed on the base, the support components including support rods and mounting shafts, a pair of support rods are respectively installed on both sides of the base, and the two ends of the mounting shaft are respectively rotatably connected to the pair of support rods; a tobacco hanging component, the tobacco hanging component including a connecting piece and a cross bar, the middle part of the connecting piece is fixedly installed on the mounting shaft, and the cross bars are respectively installed at both ends of the connecting piece; the beneficial effect of the utility model is that the mobile flue-cured tobacco hanging rack structure that is easy to disassemble: tobacco leaves can be hung on the cross bar, and when the cross bar at the top is hung, the cross bar and the fixed block can be separated by pressing down the fixed block, so that the restriction of the fixed block is lost and the cross bar can be rotated, and the cross bar is rotated 180 degrees with the mounting shaft as the center, so that the upper cross bar moves to the bottom, which is convenient for hanging tobacco leaves.

[0004] An existing Chinese patent (publication number: CN218681929U) discloses an overlapping, liftable tobacco curing rack. This utility model provides an overlapping, liftable tobacco curing rack that allows tobacco leaves to be hung on high-rise tobacco curing racks without requiring climbing. The utility model provides such an overlapping, liftable tobacco curing rack, comprising a first column, a second column, and a third column; the first column and the third column are symmetrically arranged on either side of the second column with the second column as the center, and a cross slot is defined on one side of each of the first, second, and third columns. When a high-temperature, explosion-proof motor is energized and rotated in the forward direction, the winding drum winds and tightens the drawstring, which drives the third tobacco curing rack, which is laden with tobacco leaves, upward. The third tobacco curing rack, through the cooperation of the first and second connecting plates, pulls the second tobacco curing rack, which is laden with tobacco leaves, upward.

[0005] During use of the above-mentioned tobacco rack, tobacco leaves can be hung by removing the cross bars to facilitate drying of the tobacco leaves, or the tobacco leaves can be hung by lowering the cross bars, and then the spacing between the multiple cross bars can be adjusted simultaneously to raise the tobacco leaves, thereby facilitating the drying of the tobacco leaves. However, in actual use, when the tobacco leaves are hung by removing the cross bars, the spacing between the cross bars cannot be adjusted. When the cross bars are removed, the tobacco leaves are a whole composed of multiple cross bars. If the tobacco leaves want to be hung on the cross bars at the bottom, the workers need to use tools to adjust the height of the cross bars at the bottom, otherwise the tobacco leaves will come into contact with the ground and cause pollution.

[0006] If multiple cross bars are adjusted synchronously, the spacing between the multiple cross bars will be adjusted to the same size. However, in the actual tobacco curing process, parameters such as the length and thickness of the tobacco leaves will vary depending on the variety, growth environment and picking time. In one curing process, tobacco leaves of different lengths may need to be cured. For this reason, it is necessary to further adjust the spacing between each cross bar to ensure that the hot air can circulate fully between the tobacco leaves. Utility Model Content

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] See also Figure 1-8 The utility model provides a technical solution: an adjustable hanging tobacco rack, comprising a plurality of mounting bases 1 and support rods 2 connected to the mounting bases 1, including:

[0039] There are at least three sliding rods 301, which are vertically slidable and are equally spaced between every two support rods 2;

[0040] At least two first steel cables 302 are provided, connected between every two sliding rods 301;

[0041] A second steel cable 303 is connected to one of the sliding rods 301 on a side away from the mounting base 1 , and the other end of the second steel cable 303 extends into the mounting base 1 ;

[0042] The winding roller 304 is rotatably connected to the mounting base 1 , and the other end of the second steel cable 303 is wound around the winding roller 304 .

[0043] Preferably, the first steel cable 302 and the second steel cable 303 can also be chains or ropes, as long as they can pull the slide bar 301 to slide;

[0044] The sliding rod 301 , the first steel cable 302 , the second steel cable 303 and the winding roller 304 together constitute the adjustment assembly 300 .

[0045] It should be noted that a sliding hole is provided on the support rod 2 to facilitate the sliding of the second steel cable 303 .

[0046] In practice, multiple mounting bases 1 and support rods 2 connected to the mounting bases 1 form a basic framework. Sliding rods 301 are vertically slidably arranged at equal intervals between each pair of support rods 2. To adjust the height of the sliding rods 301, a wrapping roller 304 connected to the mounting base 1 is rotated. The rotation of the wrapping roller 304 drives a second steel cable 303 connected thereto. One end of the second steel cable 303 is connected to one of the sliding rods 301 on the side away from the mounting base 1. As the wrapping roller 304 rotates, the second steel cable 303 is tightened or loosened, thereby pulling the sliding rod 301 to slide vertically between the support rods 2.

[0047] The first steel cable 302 connected between each pair of slide bars 301 serves to synchronously adjust the height of the multiple slide bars 301. When one of the slide bars 301 is pulled by the second steel cable 303, the other slide bars 301 will also move vertically synchronously through the connection of the first steel cable 302, ensuring that the slide bars 301 on the entire tobacco curing rack can be maintained at the same horizontal height for hanging and curing tobacco leaves.

[0048] Please refer to Figure 1 、 Figure 4 and Figure 5 , a telescopic assembly is provided between each two slide bars 301, including:

[0049] A connecting tube 12 is provided at the top of one of the slide rods 301 and a telescopic rod 13 is provided at the bottom of the other slide rod 301. One side of the connecting tube 12 is threadedly connected to a fixing bolt 14. The other end of the fixing bolt 14 extends into the connecting tube 12 and is rotatably connected to a fixing piece 15. The fixing piece 15 is in conflict with the outer surface of the telescopic rod 13.

[0050] In specific implementation, the telescopic assembly is used to facilitate adjustment of the spacing between the two slide bars 301, making it convenient to hang tobacco leaves of different lengths. By adjusting the distance between the slide bars 301, the tobacco leaves can be kept at an appropriate spacing, ensuring that hot air can fully circulate between the tobacco leaves, improving the uniformity of baking. When the distance between the two slide bars 301 needs to be adjusted, the fixing bolt 14 is rotated, and the fixing bolt 14 moves into the interior of the connecting tube 12 under the action of the thread of the connecting tube 12. The other end of the fixing bolt 14 extends into the connecting tube 12 and is rotatably connected to a fixing member 15. As the fixing bolt 14 moves, the fixing member 15 also approaches the telescopic rod 13 to fix the telescopic rod 13. The fixing member 15 prevents the fixing bolt 14 from falling off the connecting tube 12.

[0051] Please refer to Figure 2 and Figure 6 The mounting bases 1 are distributed in a rectangular array with equal spacing. A first transmission assembly 400 is provided on one side of the mounting base 1, including:

[0052] A drive shaft 401 is rotatably connected to one side of the mounting base 1. One end of the drive shaft 401 extends outside the mounting base 1 and is driven to rotate by the hoist 305. The drive shaft 401 rotatably connected to the mounting base 1 in the middle is connected to a first synchronous pulley 402 and a second synchronous pulley 403 at equal intervals along the direction in which the drive shaft 401 extends.

[0053] A third synchronous wheel 405 is connected to the driving shaft 401 on both sides away from the central mounting base 1, and the positions of the two third synchronous wheels 405 are different. One of the third synchronous wheels 405 is in the same horizontal plane as the first synchronous wheel 402, and the other third synchronous wheel 405 is in the same horizontal plane as the second synchronous wheel 403. The two third synchronous wheels 405 are respectively connected to the first synchronous wheel 402 and the second synchronous wheel 403 by a first synchronous belt 404.

[0054] Preferably, the first synchronous wheel 402, the second synchronous wheel 403 and the third synchronous wheel 405 can also be connected by a sprocket and a chain for transmission, as long as the driving shaft 401 on both sides can be driven to rotate by the driving shaft 401 in the middle.

[0055] In specific implementation, when adjusting the height of the slide bar 301 , the hoist 305 drives the drive shaft 401 located on the middle mounting base 1 to rotate. The first synchronous wheel 402 and the second synchronous wheel 403 on the drive shaft 401 rotate together with the drive shaft 401 .

[0056] For the drive shaft 401 away from the two sides of the central mounting base 1, two third synchronous wheels 405 at different positions are connected thereto, one of the third synchronous wheels 405 is connected to the first synchronous wheel 402 on the central drive shaft 401 through a first synchronous belt 404, and the other third synchronous wheel 405 is connected to the second synchronous wheel 403 on the central drive shaft 401 through a first synchronous belt 404.

[0057] In this way, when the driving shaft 401 in the middle rotates, the driving shafts 401 on both sides are driven to rotate synchronously through the transmission of the first synchronous belt 404, providing a unified power source for the subsequent height adjustment of the sliding rod 301, ensuring that the sliding rods 301 on each mounting base 1 can be adjusted in height synchronously.

[0058] See Figure 6 A second transmission assembly 500 is also provided in the mounting base 1, including a connecting shaft 501 coaxially arranged with the winch 305, a fourth synchronous wheel 502 is rotatably connected in the mounting base 1, the fourth synchronous wheel 502 is connected to the drive shaft 401, and a second synchronous belt 503 is connected between the connecting shaft 501 and the fourth synchronous wheel 502.

[0059] In specific implementation, when the hoist 305 is working, it drives the connecting shaft 501 coaxially arranged therewith to rotate. The connecting shaft 501 transmits power to the fourth synchronous wheel 502 rotatably connected in the mounting base 1 through the second synchronous belt 503, so that the fourth synchronous wheel 502 can drive the driving shaft 401 to rotate.

[0060] See Figure 7 , the drive shaft 401 is connected to a first bevel gear 6, the mounting base 1 is rotatably connected to a second bevel gear 7, the second bevel gear 7 and the first bevel gear 6 are engaged with each other, the second bevel gear 7 is coaxially arranged with the winding roller 304.

[0061] Specifically, the first bevel gear 6 and the second bevel gear 7 can be used in conjunction with each other so that the driving shaft 401 drives the winding roller 304 to rotate during the rotation process, thereby facilitating the retraction of the second steel cable 303 .

[0062] Please refer to Figure 3 and Figure 8 The top of the support rod 2 is connected to a pulley seat 8, a roller is rotatably provided in the pulley seat 8, and the second steel cable 303 is overlapped on the roller.

[0063] Specifically, the second steel cable 303 is overlapped on the roller. When the wrapping roller 304 rotates, the second steel cable 303 slides on the roller. The rotation of the roller makes the movement of the second steel cable 303 smoother, reducing the friction of the second steel cable 303.

[0064] Please refer to Figure 8 A slide groove 9 is provided in the support rod 2 , and the slide groove 9 is adapted to the slide rod 301 , and the slide rod 301 is slidably connected in the slide groove 9 .

[0065] Specifically, the sliding groove 9 provides a limit and guide for the sliding of the sliding rod 301, thereby improving the stability of the sliding rod 301 during the sliding process.

[0066] See Figure 1 , The support rod 2 is connected to a connecting plate 10, and the connecting plate 10 is provided with a threaded hole.

[0067] Specifically, this arrangement facilitates fixing of the support rod 2 .

[0068] refer to Figure 3 A fixing rod 11 is connected between the support rods 2 on both sides away from the middle mounting base 1.

[0069] Specifically, this arrangement improves the stability of the support rod 2 during use.

[0070] refer to Figure 5The bottom of the telescopic rod 13 is connected to a limiting disc 16, and the top of the connecting tube 12 is connected to a limiting ring 17. The limiting ring 17 is used to cooperate with the limiting disc 16 to limit the sliding position of the telescopic rod 13.

[0071] During specific implementation, the limiting disc 16 can be used in conjunction with the limiting ring 17 to prevent the telescopic rod 13 from slipping.

[0072] Working Principle: During use, multiple mounting bases 1 and support rods 2 connected to the mounting bases 1 form a basic framework. Sliding rods 301 are vertically slidably arranged at equal intervals between each pair of support rods 2. To adjust the height of the sliding rods 301, the height is adjusted by rotating a wrapping roller 304 connected to the mounting base 1. This rotation of the wrapping roller 304 drives a second steel cable 303 connected to it. One end of the second steel cable 303 is connected to one of the sliding rods 301 on the side away from the mounting base 1. As the wrapping roller 304 rotates, the second steel cable 303 is tightened or loosened, thereby pulling the sliding rod 301 to slide vertically between the support rods 2.

[0073] The first steel cable 302 connected between each pair of slide bars 301 serves to synchronously adjust the height of the multiple slide bars 301. When one slide bar 301 is pulled by the second steel cable 303, the other slide bars 301 will also move vertically synchronously through the connection of the first steel cable 302, ensuring that the slide bars 301 on the entire tobacco curing rack can be maintained at the same horizontal height, facilitating the hanging and curing of tobacco leaves.

[0074] The telescopic assembly is used to facilitate adjustment of the spacing between the two slide bars 301, making it easier to hang tobacco leaves of different lengths. By adjusting the distance between the slide bars 301, the tobacco leaves can be kept at an appropriate distance, ensuring that hot air can fully circulate between the tobacco leaves and improving baking uniformity. When the distance between the two slide bars 301 needs to be adjusted, the fixing bolt 14 is rotated, and the fixing bolt 14 moves into the interior of the connecting tube 12 under the action of the thread of the connecting tube 12. The other end of the fixing bolt 14 extends into the connecting tube 12 and is rotatably connected to a fixing member 15. As the fixing bolt 14 moves, the fixing member 15 also moves closer to the telescopic rod 13 to secure the telescopic rod 13. The fixing member 15 prevents the fixing bolt 14 from falling off the connecting tube 12.

[0075] When the height of the slide bar 301 is adjusted, the hoist 305 drives the drive shaft 401 located on the middle mounting base 1 to rotate. The first synchronous wheel 402 and the second synchronous wheel 403 on the drive shaft 401 rotate together with the drive shaft 401.

[0076] For the drive shaft 401 away from the two sides of the central mounting base 1, two third synchronous wheels 405 at different positions are connected thereto, one of the third synchronous wheels 405 is connected to the first synchronous wheel 402 on the central drive shaft 401 through a first synchronous belt 404, and the other third synchronous wheel 405 is connected to the second synchronous wheel 403 on the central drive shaft 401 through a first synchronous belt 404.

[0077] In this way, when the driving shaft 401 in the middle rotates, the driving shafts 401 on both sides are driven to rotate synchronously through the transmission of the first synchronous belt 404, providing a unified power source for the subsequent height adjustment of the sliding rod 301, ensuring that the sliding rods 301 on each mounting base 1 can be adjusted in height synchronously.
