Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of tobacco curing equipment, specifically to a liftable tobacco hanging device. Background Technology
[0002] Currently, when tobacco leaves arranged in rows on hanging rods are hung in the tobacco curing barn, the internal height of the barn is relatively high, and the frames used to hang the tobacco leaves are all fixed. It is necessary to use ladders or other climbing equipment to climb and hang them. This method of taking and hanging tobacco leaves in rows is labor-intensive, requires multiple climbs, and is very inefficient. In addition, this method of taking and hanging tobacco leaves in rows is unsafe, as operators are at risk of falling while climbing, which is not safe enough. Utility Model Content
[0003] In view of this, the present invention provides a lifting and lowering tobacco hanging device to solve the problems of low work efficiency and insufficient safety of manual climbing to retrieve and hang tobacco leaves.
[0004] This utility model provides a height-adjustable cigarette hanging device, suitable for installing and raising / lowering cigarette hanging rods, including:

[0007] A plurality of mating blocks are movably disposed on the suspension rod, and each suspension rod has at least one of the mating blocks;
[0008] A plurality of driving components are connected to at least one of the suspension rods and adapted to drive the suspension rods to rotate, causing the mating block to move along the axial direction of the suspension rods;
[0009] The cigarette holder is connected to several of the aforementioned mating blocks and is adapted to suspend the cigarette rod. The mating blocks are driven to move so as to raise or lower the cigarette holder, thereby raising or lowering the cigarette rod.
[0010] Beneficial effects: This utility model provides a liftable tobacco hanging device. The suspension rod and the matching block on the suspension rod provided on the main frame provide the installation position for the tobacco hanging frame. The tobacco hanging rod is installed horizontally on the tobacco hanging frame. After the tobacco hanging rod is installed in place, the suspension rod can be driven to rotate by the drive component, which in turn drives the matching block to move along the axial direction of the suspension rod. This causes the tobacco hanging frame to rise or fall with the movement of the matching block, which in turn drives the tobacco hanging rod to rise or fall. This makes it easy to raise the tobacco hanging rod to a high place to bake the tobacco leaves or lower it to a low place to collect the tobacco leaves. There is no need for manual climbing to high places, which improves the efficiency and safety of the tobacco leaf collection operation.
[0011] In one optional embodiment, the number of driving components and suspension rods are the same, and they are connected in a one-to-one transmission connection; the mating block is connected in a transmission connection with the suspension rod.
[0012] Beneficial effects: Multiple drive components are set up to simultaneously drive multiple suspension rods to rotate, and then multiple mating blocks move synchronously to drive the cigarette rack and the cigarette rods on it to rise and fall, thereby improving the operational stability of the cigarette rod lifting and lowering.
[0013] In one optional embodiment, the cigarette rack includes two crossbeams, and the suspension rod, the mating block, and the driving component are correspondingly arranged to form four sets of driving components. The two sets of driving components on the same side are connected to one of the crossbeams to drive the two crossbeams of the cigarette rack to rise or fall synchronously.
[0014] Beneficial effects: The tobacco hanging rack is equipped with two crossbeams, which allows each layer of the tobacco hanging rack to suspend multiple tobacco hanging rods horizontally across the two crossbeams, thereby improving the tobacco curing efficiency and the operational stability of the tobacco hanging rack.
[0015] In one alternative embodiment, the suspension rod is configured as a rotating lead screw, and the mating block is configured as a lead screw nut.
[0016] Beneficial effects: By setting the suspension rod as a rotating lead screw and the mating block as a lead screw nut that is connected to the suspension rod in a transmission, the rotation of the suspension rod can drive the mating block to move along the axial direction of the suspension rod, thereby driving the cigarette rack and the cigarette rod on it to rise and fall.
[0017] In one optional embodiment, each of the suspension rods is provided with a plurality of mating blocks, and the cigarette racks are provided with a plurality of mating blocks, each of the plurality of cigarette racks being connected to a corresponding mating block, and any one of the cigarette racks being adapted to suspend a plurality of cigarette rods.
[0018] Beneficial effects: In the above embodiments, multiple mating blocks are provided on the suspension rod to facilitate the installation of multiple tobacco hanging frames and multiple tobacco hanging rods to hang tobacco leaves at the same time, thereby improving the tobacco curing efficiency.
[0019] In one alternative embodiment, the liftable cigarette holder further includes a clutch component disposed on the mating block, the clutch component being adapted to grip or release the suspension rod;
[0020] When the clutch engages, the mating block is adapted to move along the axial direction of the suspension rod;
[0021] When the clutch is released, the suspension rod is adapted to rotate freely relative to the mating block.
[0022] Beneficial effect: When each suspension rod is equipped with multiple mating blocks, by setting a clutch on the mating blocks, the four mating blocks corresponding to each layer of cigarette rack can move relative to the other mating blocks, thereby driving each cigarette rack to rise and fall one by one.
[0023] In one alternative embodiment, the driving component is a worm gear motor, wherein the worm of the worm gear motor is collinearly connected to the suspension rod.
[0024] Beneficial effects: In the above embodiments, the worm of the worm gear motor is connected collinearly with the suspension rod, thereby driving the suspension rod to rotate. The worm gear motor can provide sufficient driving power to ensure that the suspension rod rotates stably and smoothly.
[0025] In one optional embodiment, the top of the main frame is provided with a clearance hole, the drive component is mounted on the main frame, and the suspension rod extends through the clearance hole and extends downward.
[0026] Beneficial effects: The main frame provides an installation position for the drive component. An obstacle avoidance hole is provided at the top of the main frame to allow the suspension rod that is connected to the drive component to pass through, thus avoiding installation interference between the suspension rod and the main frame.
[0027] In one alternative embodiment, the distance between the suspension rod and the ground ranges from 1m to 1.3m.
[0028] Beneficial effect: Limiting the height of the suspension rod from the ground makes it easier for operators to install the cigarette hanger directly from the ground. Attached Figure Description

[0043] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0044] The following is combined with Figure 1 The following describes embodiments of the present invention.
[0045] According to an embodiment of this utility model, a height-adjustable cigarette hanging device is provided, suitable for installing and raising / lowering the cigarette hanging rod 1, such as... Figure 1 As shown, it includes: main frame 2, suspension rod 3, mating block 4, drive component 5, and cigarette rack 6.
[0046] A number of suspension rods 3 are spaced apart on the main frame 2; a number of mating blocks 4 are movably provided on the suspension rods 3, and each suspension rod 3 has at least one mating block 4; a number of driving members 5 are connected to at least one suspension rod 3 and are adapted to drive the suspension rod 3 to rotate, so that the mating blocks 4 move along the axial direction of the suspension rod 3; the cigarette rack body 6 is connected to the number of mating blocks 4 and is adapted to suspend the cigarette rack 1, and the mating blocks 4 are driven to move to drive the cigarette rack body 6 to rise or fall, thereby driving the cigarette rack 1 to rise or fall.
[0047] In the above embodiment, the suspension rod 3 and the mating block 4 on the suspension rod 3 provided by the main frame 2 provide an installation position for the tobacco hanging frame 6. The tobacco hanging rod 1 is installed horizontally on the tobacco hanging frame 6. After the tobacco hanging rod 1 is installed in place, the suspension rod 3 can be driven to rotate by the drive component 5, which in turn drives the mating block 4 to move along the axial direction of the suspension rod 3. This causes the tobacco hanging frame 6 to rise or fall with the movement of the mating block 4, which in turn drives the tobacco hanging rod 1 on it to rise or fall. This makes it easier to raise the tobacco hanging rod 1 to a high place to bake the tobacco leaves or lower it to a low place to collect the tobacco leaves. There is no need for manual climbing to high places, which improves the efficiency and safety of the tobacco leaf collection operation.
[0048] Specifically, such as Figure 1 As shown, the tobacco hanging rod 1 has multiple hanging positions at intervals for hanging tobacco leaves; the main frame 2 is the main support structure, providing an installation base for the suspension rod 3, the mating block 4, the drive component 5, and the tobacco hanging frame 6; the top of the suspension rod 3 is installed and suspended at the lower part of the main frame 2 so that the tobacco leaves can be hung for drying after the tobacco hanging rod 1 is installed on the tobacco hanging frame 6 on its mating block 4.
[0049] Furthermore, such as Figure 1 As shown, the mating block 4 is movably disposed on the suspension rod 3, including at least two implementation methods. First, the mating block 4 is drive-connected to the suspension rod 3, so that rotation of the suspension rod 3 directly drives the mating block 4 to move axially along the suspension rod 3. Second, the mating block 4 is sleeved on the outside of the suspension rod 3, in which case the suspension rod 3 only serves as a track structure, providing only a guiding function for the mating block 4. The liftable cigarette holder provided in this embodiment also has two implementation methods.
[0050] In one implementation, each suspension rod 3 is connected to its corresponding mating block 4 in a transmission manner, and multiple driving components 5 drive multiple suspension rods 3 to rotate. Each mating block 4 moves along the axial direction of its respective suspension rod 3 to synchronously drive the cigarette rack body 6 and the cigarette rod 1 on it to rise or fall.
[0051] In one implementation, the suspension rod 3 is divided into two groups: one group serves as a force-transmitting suspension rod, and the other group serves as a guide suspension rod. The mating block 4 on the force-transmitting suspension rod is connected to it in a transmission manner, and the mating block 4 on the guide suspension rod is sleeved onto it. The driving component 5 is only connected to the force-transmitting suspension rod in a transmission manner to drive the cigarette rack body 6 and its cigarette hanging rod 1 to rise or fall. At this time, the guide suspension rod engages with the sleeved mating block 4 on it, providing a guiding function for the cigarette rack body 6. This configuration results in a relatively simple overall structure, helping to save on production and installation costs.
[0052] Furthermore, this embodiment does not limit the specific structural form of the cigarette rack 6. As one implementation, the cigarette rack 6 is configured as a rectangular frame with two opposite sides serving as longitudinally extending crossbeams, which are fixedly connected to corresponding mating blocks 4; as another implementation, such as... Figure 2 , Figure 3 As shown, the cigarette rack body 6 is directly designed as two longitudinally extending crossbeams of a split structure, and the two crossbeams are fixedly connected to the corresponding mating blocks 4.
[0053] In the above two structural forms of cigarette rack 6, the cigarette rod 1 on each layer of cigarette rack 6 can be suspended horizontally across two crossbeams, thereby suspending multiple cigarette rods 1 side by side in the longitudinal direction.
[0054] The liftable cigarette hanging device provided in this embodiment has two implementation methods for its own assembly structure.
[0055] As one implementation method, such as Figure 2 As shown, the liftable cigarette hanging device is equipped with two sets of suspension rods 3, mating blocks 4, and driving components 5. The two crossbeams of the cigarette hanging frame 6 are fixedly connected to the two mating blocks 4 respectively. In this way, only two driving components 5 are needed to drive the two crossbeams of the cigarette hanging frame 6 to run synchronously. The mating blocks 4 are connected to the middle of the crossbeams so that the crossbeams remain balanced when driven. At the same time, the simplified design of the structure can also reduce the design cost of the liftable cigarette hanging device.
[0056] As another implementation method, such as Figure 3 As shown, the liftable cigarette hanging device is equipped with four sets of suspension rods 3, mating blocks 4, and driving components 5. Each crossbeam of the cigarette hanging frame 6 is fixedly connected to two mating blocks 4 on the same side. That is, the two crossbeams of the cigarette hanging frame 6 are fixedly connected by four mating blocks 4. In this way, the two crossbeams of the cigarette hanging frame 6 are driven synchronously by four driving components 5, thereby improving the operational stability of the cigarette hanging frame 6. It should be noted that, as a preferred embodiment, the connection point between the mating block 4 and the crossbeam is located slightly further away from the end of the crossbeam. For example, if the length of the crossbeam is five meters, the connection point between the mating block 4 and the crossbeam is located about one meter away from the end of the crossbeam, thereby avoiding excessive load on the middle of the crossbeam and bending.
[0057] In some embodiments, such as Figure 1 As shown, the number of driving components 5 and suspension rods 3 are the same, and they are connected in a one-to-one transmission connection; the mating block 4 is connected to the suspension rods 3 in a transmission connection.
[0058] In the above embodiment, multiple driving components 5 are provided to simultaneously drive multiple suspension rods 3 to rotate, and then multiple mating blocks 4 move synchronously to drive the cigarette rack body 6 and the cigarette rod 1 on it to rise and fall, thereby improving the operational stability of the cigarette rod 1 rising and falling.
[0059] Specifically, by setting up multiple sets of drive structures, each connection point between the cigarette rack 6 and the mating block 4 can perform synchronous lifting and lowering movements, avoiding jamming at any point of the cigarette rack 6 during operation, thereby improving the operational stability of the cigarette rack 6 and the cigarette rod 1 on it.
[0060] Furthermore, the driving component 5 can be a worm gear motor, a direct drive motor, or the like.
[0061] In some embodiments, such as Figure 1 As shown, in a preferred embodiment, the cigarette rack body 6 includes two crossbeams, a suspension rod 3, a mating block 4, and a driving component 5, which are correspondingly arranged to form four sets of driving components. The two sets of driving components on the same side are connected to a crossbeam for transmission, so as to drive the two crossbeams of the cigarette rack body 6 to rise or fall synchronously.
[0062] In the above embodiment, the tobacco hanging rack 6 is provided with two crossbeams, so that each layer of the tobacco hanging rack 6 can span the two crossbeams and suspend multiple tobacco hanging rods 1 in the horizontal direction, thereby improving the tobacco curing efficiency and the operational stability of the tobacco hanging rack 6.
[0063] Specifically, such as Figure 1 The figure shows a vertical sectional view of the liftable cigarette hanging device. Only two sets of suspension rods 3, mating blocks 4, and driving components 5 are shown, and only the cross-sections of two crossbeams are shown of the cigarette hanging frame 6. In reality, the depth of the liftable cigarette hanging device can reach several meters. Figure 2 , Figure 3 As shown, the lifting and lowering is driven by a drive assembly consisting of four sets of suspension rods 3, mating blocks 4, and drive components 5 located on the two crossbeams.
[0064] Furthermore, since the depth of a typical tobacco curing barn exceeds six meters, the depth of each layer of the tobacco hanging rack 6 is more than five meters, which can suspend dozens of tobacco hanging rods 1.
[0065] In some embodiments, such as Figure 1 As shown, the suspension rod 3 is a rotating lead screw, and the mating block 4 is a lead screw nut.
[0066] In the above embodiment, the suspension rod 3 is set as a rotating screw, and the mating block 4 is set as a screw nut that is connected to the suspension rod 3 in a transmission manner, so that the suspension rod 3 can be driven to rotate and drive the mating block 4 to move along the axial direction of the suspension rod 3, thereby driving the cigarette rack body 6 and the cigarette rod 1 on it to rise and fall.
[0067] Specifically, the inner ring structure of the mating block 4 is configured to connect the thread of the lead screw nut with the rotating lead screw for transmission. The outer part of the mating block 4 is used to fix it to the cigarette rack body 6. The two ends of the cigarette rod 1 are respectively attached to the cigarette rack body 6 so that the suspension rod 3 can be driven to rotate and drive the cigarette rack body 6 and the cigarette rod 1 on it to rise and fall through the mating block 4.
[0068] Furthermore, as an alternative implementation, the suspension rod 3 is a threaded rod, and the mating block 4 is a screw nut that is threadedly connected to the suspension rod 3. The inner ring structure of the mating block 4 is configured such that the thread of the screw nut is connected to the threaded rod and performs transmission engagement. The outer part of the mating block 4 is used to fix it to the cigarette rack body 6. The two ends of the cigarette rack 1 are respectively attached to the cigarette rack body 6 so that the suspension rod 3 can be driven to rotate and drive the cigarette rack body 6 and the cigarette rack 1 on it to rise and fall through the mating block 4.
[0069] In some embodiments, such as Figure 1 As shown, each suspension rod 3 is provided with multiple mating blocks 4, and multiple cigarette racks 6 are provided. The multiple cigarette racks 6 are connected to the corresponding mating blocks 4 respectively, and any cigarette rack 6 is suitable for suspending multiple cigarette rods 1.
[0070] In the above embodiment, multiple mating blocks 4 are provided on the suspension rod 3 to facilitate the installation of multiple tobacco hanging racks 6 and multiple tobacco hanging rods 1 to hang tobacco leaves simultaneously, thereby improving the tobacco curing efficiency.
[0071] Specifically, in this embodiment, each suspension rod 3 of the liftable cigarette hanging device is provided with four mating blocks 4, and the number of mating blocks 4 on each suspension rod 3 is the same, so that four cigarette hanging racks 6 can be fixedly connected and installed at the same time.
[0072] Furthermore, the number of mating blocks 4 on each suspension rod 3 can be two, three, five, six, or even more.
[0073] In some embodiments, such as Figure 1 As shown, the liftable cigarette holder also includes a clutch component located on the mating block 4. The clutch component is adapted to grip or release the suspension rod 3. When the clutch component grips, the mating block 4 is adapted to move along the axial direction of the suspension rod 3. When the clutch component releases, the suspension rod 3 is adapted to rotate relative to the mating block 4.
[0074] In the above embodiment, when each suspension rod 3 is provided with multiple mating blocks 4, by setting a clutch on the mating block 4, the four mating blocks 4 corresponding to each layer of cigarette rack 6 can move relative to the other mating blocks 4 respectively, thereby driving each cigarette rack 6 to rise and fall one by one.
[0075] Specifically, taking the distribution of multiple mating blocks 4 on the suspension rod 3 from top to bottom as an example, the uppermost mating block 4 is the first mating block 4, and the four uppermost mating blocks 4 on the four suspension rods 3 form the first group of mating blocks 4, which together connect to the uppermost tobacco hanging rack 6. When suspending tobacco leaves for drying, after the operator hangs the uppermost tobacco hanging rack 6 with the tobacco hanging rods 1, the clutches of the four mating blocks 4 in the first group of mating blocks 4 tighten while the clutches of the remaining mating blocks 4 loosen. The drive unit 5 is then activated to lift the uppermost tobacco hanging rack 6 and its tobacco hanging rods 1 into position. After that, the operator hangs the second, i.e., the next uppermost tobacco hanging rack 6 with the tobacco hanging rods 1. At this time, the clutches of the four mating blocks 4 in the second group of mating blocks 4 tighten while the clutches of the remaining mating blocks 4 loosen. The drive unit 5 is then activated to lift the second, i.e., the next uppermost tobacco hanging rack 6 into position below the uppermost tobacco hanging rack 6. Subsequent tobacco hanging racks 6 and their tobacco hanging rods 1 are then installed and suspended in this manner. The procedure for harvesting tobacco leaves is similar to that described above, and will not be repeated here.
[0076] Furthermore, the clutch can be configured as a friction clutch, a jaw clutch, an electromagnetic clutch, etc.
[0077] In some embodiments, such as Figure 1 As shown, the driving component 5 is a worm gear motor, and the worm of the worm gear motor is connected collinearly with the suspension rod 3.
[0078] In the above embodiment, the worm of the worm gear motor is connected collinearly with the suspension rod 3, thereby driving the suspension rod 3 to rotate. The worm gear motor can provide sufficient driving power to ensure that the suspension rod 3 rotates stably and smoothly.
[0079] Specifically, the worm gear motor includes a meshing worm wheel and a worm. The worm wheel outputs rotational power and transmits the power to the worm through the meshing part, causing the worm to rotate and drive the suspension rod 3 connected to it along the same line to rotate. The torque transmission between the worm wheel and the worm increases the driving power of the suspension rod 3.
[0080] Furthermore, as an alternative implementation, the drive unit 5 is configured as a direct drive motor, with the output shaft of the direct drive motor connected collinearly with the suspension rod 3 to directly drive the suspension rod 3 to rotate.
[0081] In some embodiments, such as Figure 1 As shown, the top of the main frame 2 is provided with a clearance hole, the drive component 5 is installed on the main frame 2, and the suspension rod 3 extends through the clearance hole and extends downward.
[0082] In the above embodiment, the main frame 2 provides an installation position for the drive component 5, and an avoidance hole is provided on the top of the main frame 2 so that the suspension rod 3, which is connected to the drive component 5, can pass through, so as to avoid installation interference between the suspension rod 3 and the main frame 2.
[0083] Specifically, the top of the main frame 2 is provided with four clearance holes (only two are shown in the figure), and four drive components 5 are respectively installed on the main frame 2 near the four clearance holes. Four suspension rods 3 are respectively passed through the four clearance holes and extended downwards.
[0084] In some embodiments, such as Figure 1 As shown, the distance between the suspension rod 3 and the ground ranges from 1m to 1.3m.
[0085] In the above embodiment, the height of the suspension rod 3 from the ground is limited so that the operator can directly install the cigarette hanger 1 on the ground.
[0086] Specifically, the distance between the suspension rod 3 and the ground is preferably 1.1m.
[0087] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
