Description

Technical Field

[0001] This application relates to the field of tobacco curing technology, and in particular to a lifting and unloading tobacco device. Background Technology

[0002] In tobacco production, tobacco curing is primarily used to improve the quality and flavor of tobacco leaves. Currently, tobacco leaves are mainly cured in intensive curing barns, which include a heating chamber and a loading chamber. The loading chamber contains tobacco racks, traditionally consisting of two or more layers of tobacco pillows. Each layer has three pillows (left, center, and right), all on the same horizontal plane, and the height of each layer is fixed. When tobacco needs to be hung on racks with three or more layers, the considerable height often necessitates manual climbing or the use of ladders for hanging and unloading, which is quite laborious. Summary of the Invention

[0003] The purpose of this application is to provide a lifting and unloading device for tobacco, which solves the problem that hanging and unloading tobacco on a tobacco rack is laborious in related technologies.

[0004] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0005] This application provides a lifting-type loading and unloading smoke device, including:

[0006] Base;

[0007] A bracket, which is disposed on the base;

[0008] A conveying assembly, comprising: a first sprocket, a second sprocket, and a transmission chain; the first sprocket and the second sprocket are respectively rotatably mounted on a support, and in the direction of gravity, the first sprocket is located above the second sprocket, and the first sprocket and the second sprocket are connected by the transmission chain;

[0009] A support member is disposed on the transmission chain, and the support member is provided with a support groove to support the cigarette holder.

[0010] This solution uses a support member mounted on a transmission chain to support the tobacco hanging rod. The transmission chain moves the support member up and down, which in turn moves the tobacco hanging rod, thus meeting the needs of hanging and unloading tobacco on higher tobacco racks. During loading, the woven tobacco hanging rod is placed in the support groove. Next, the device is moved into the curing barn, and the support is rotated so that the hanging rod is no longer intersecting the tobacco rack in the direction of gravity. Then, the conveyor chain is manually or otherwise driven to raise the hanging rod to a horizontal height above the desired tobacco rack level. The support is then rotated again until both ends are above the tobacco rack. The support member is lowered to allow the hanging rod to rest against the tobacco rack. The above operation is repeated at the next hanging position to complete the entire tobacco hanging process. During unloading, the support member is raised via the transmission chain, lifting the hanging rod off the tobacco rack. The support is then rotated so that the hanging rod is no longer intersecting the tobacco rack in the direction of gravity. Then, the cigarette holder can be lowered via the transmission chain.

[0011] Optionally, the bracket includes a lifting assembly and a support plate. The lifting assembly is disposed on the base and connected to the support plate for driving the support plate to move up and down along the direction of gravity. The conveying assembly is disposed on the support plate.

[0012] Optionally, the lifting assembly includes: a guide column, a crossbeam, a lifting rod, and an electro-hydraulic push rod. The guide column is disposed on the base and has a guide hole. The lifting rod is slidably disposed in the guide hole, and the top end of the lifting rod is connected to the support plate. The base of the electro-hydraulic push rod is connected to the guide column through the crossbeam, and the output end of the electro-hydraulic push rod is connected to the support plate.

[0013] To avoid excessive overall height of the device, the support frame in this design includes a lifting assembly and a support plate. The conveying assembly is mounted on the support plate. When not in use, the height of the support plate can be lowered using the lifting assembly, thereby reducing the overall height of the device and facilitating the placement of the tobacco hanging rod. When loading tobacco, the tobacco hanging rod can be placed in the bearing groove first, and then the lifting assembly can be used to raise it, ensuring that the top of the transmission chain exceeds the tobacco layer at a horizontal height, thus ensuring that the tobacco hanging rod is raised above the tobacco layer.

[0014] Optionally, the guide column is provided with a handrail.

[0015] The addition of a handrail facilitates adjustment of the bracket's position, thereby simplifying the adjustment of the cigarette hanger's position and angle. Furthermore, it makes aligning the support groove with the cigarette hanger easier when unloading cigarettes.

[0016] Optionally, the support component includes: a lifting arm connected to the transmission chain, a support block on the lifting arm, and a support groove located on the support block.

[0017] Optionally, the lifting arm and the supporting block are integrally formed.

[0018] Optionally, there are multiple first sprockets, multiple second sprockets and multiple transmission chains, with each of the multiple first sprockets, multiple second sprockets and multiple transmission chains corresponding to one another. The conveying assembly also includes a first transmission shaft and a second transmission shaft rotatably mounted on the bracket. Multiple first sprockets are axially mounted on the first transmission shaft, multiple second sprockets are axially mounted on the second transmission shaft, and multiple support members are correspondingly mounted on the multiple transmission chains.

[0019] To ensure the stability of the cigarette holder supported by the support components, this design incorporates multiple first sprockets, multiple second sprockets, and multiple drive chains. These multiple first sprockets, second sprockets, and drive chains correspond one-to-one, forming multiple parallel transmission structures. The conveying assembly also includes a first drive shaft and a second drive shaft rotatably mounted on the bracket. Multiple first sprockets are axially mounted on the first drive shaft, and multiple second sprockets are axially mounted on the second drive shaft, thereby achieving synchronous movement of multiple drive chains in the same direction. The support components on these multiple drive chains are correspondingly arranged, thus collaboratively supporting the cigarette holder and increasing its stability on the support components.

[0020] Optionally, the bracket is provided with a driving component, which is connected in a transmission manner to at least one of the first sprocket and the second sprocket.

[0021] This solution uses a driving component to drive the first and second sprockets to rotate, thereby driving the transmission chain to move. In some embodiments, the driving component is a drive motor, and the output shaft of the drive motor is connected to the first sprocket for transmission. The drive motor drives the first sprocket to rotate, thereby driving the transmission chain to move.

[0022] Optionally, the base includes a base plate and a turntable, the turntable being rotatably mounted on the top surface of the base plate via a rotating shaft, and the lifting assembly being mounted on the top surface of the turntable.

[0023] In this design, the base includes a base plate and a turntable. During the loading and unloading of cigarettes, the cigarette hanging rod needs to be rotated; this design allows for convenient rotation of the hanging rod via the turntable. Furthermore, during unloading, to ensure the hanging rod is aligned with the support groove, the angle of the support needs fine-tuning; the turntable allows for more precise angle adjustment.

[0024] Optionally, the bottom of the base plate is provided with casters.

[0025] Compared with existing technologies, the beneficial effects achieved by this application are as follows: This application uses a support member to support the tobacco hanging rod, and the support member is mounted on a transmission chain. The movement of the transmission chain can drive the support member to move up and down, thereby moving the tobacco hanging rod. When loading tobacco, this application can place the tobacco hanging rod on the support member at a lower position, and then the conveying component transports the tobacco hanging rod to the top of the layer to be hung on the tobacco hanging rack. The position of the tobacco hanging rod is adjusted by a rotating device so that the tobacco hanging rod rests against the tobacco hanging rack, thus completing the loading. Similarly, when unloading tobacco, the support member is lifted by the transmission chain, and the support member lifts the tobacco hanging rod away from the tobacco hanging rack. The position of the tobacco hanging rod is adjusted by a rotating device, and then the tobacco hanging rod is lowered to complete the unloading. This application effectively solves the problem of laborious tobacco hanging and unloading due to the high height of the tobacco hanging rack. It is especially suitable for batch operation scenarios in multi-layer tobacco drying barns, greatly reducing labor intensity and operation time, and significantly improving the efficiency of tobacco hanging and unloading.

Detailed Implementation

[0033] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure / application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0034] Example 1

[0035] This embodiment describes a lifting and unloading smoke device, referencing... Figure 1 The lifting and unloading smoke device in this embodiment includes a base 1, a support 2 on the base 1, and a conveying assembly 3 on the support 2. The conveying assembly 3 includes a first sprocket 31, a second sprocket 32, and a transmission chain 33. The first sprocket 31 and the second sprocket 32 ​​are rotatably mounted on the support 2, and their axial directions are the same. The first sprocket 31 is located above the second sprocket 32. In some embodiments, the first sprocket 31 is located directly above the second sprocket 32. Further, the transmission chain 33 is sleeved on the first sprocket 31 and the second sprocket 32. The first sprocket 31 and the second sprocket 32 ​​can be driven by the transmission chain 33; similarly, the transmission chain 33 can rotate through the first sprocket 31 and the second sprocket 32.

[0036] Furthermore, a support member 4 is provided on the transmission chain 33, and a support groove 41 is provided on the support member 4. The top opening of the support groove 41 is suitable for supporting the cigarette holder. It should be noted that in this embodiment, there can be one or more support members 4.

[0037] This solution uses a support member 4 to support the tobacco hanging rod, which is mounted on a transmission chain 33. The movement of the transmission chain 33 causes the support member 4 to move up and down, thereby moving the tobacco hanging rod to meet the needs of hanging and unloading tobacco on higher tobacco racks. When loading tobacco, the woven tobacco hanging rod is placed in the support groove 41. Next, the device is moved into the curing barn, and the support bracket 2 is rotated so that the tobacco hanging rod does not intersect the tobacco rack in the direction of gravity. Then, the conveyor chain is manually or otherwise driven to raise the tobacco hanging rod to a horizontal height higher than the desired tobacco rack level. The support bracket 2 is then rotated again until both ends are above the tobacco rack. The support member 4 is lowered so that the tobacco hanging rod rests against the tobacco rack. The above operation is repeated at the next tobacco hanging position to complete the entire tobacco hanging process. When unloading tobacco, the support member 4 is raised via the transmission chain 33, lifting the tobacco hanging rod off the tobacco rack. Next, rotate the bracket 2 to rotate the cigarette hanging rod until it does not intersect the cigarette hanging frame in the direction of gravity. Then, lower the cigarette hanging rod via the transmission chain 33. It should be noted that when there are multiple support members 4, the multiple support members 4 can be arranged at intervals according to the height of each layer of the cigarette hanging frame, so as to realize multi-level synchronous cigarette hanging operation and ensure that the needs of multi-level cigarette hanging and unloading are met at one time.

[0038] refer to Figure 4 In some embodiments, to ensure the stability of the support member 4 in supporting the cigarette holder, there can be multiple first sprockets 31, second sprockets 32, and transmission chains 33. These multiple first sprockets 31, second sprockets 32, and transmission chains 33 correspond one-to-one, forming multiple parallel transmission structures, thereby enabling the multiple transmission chains 33 to move in the same direction. To ensure the synchronous movement of the multiple transmission chains 33, the conveying assembly 3 also includes a first transmission shaft 34 and a second transmission shaft 35 rotatably mounted on the bracket 2. Multiple first sprockets 31 are axially mounted on the first transmission shaft 34, and multiple second sprockets are axially mounted on the second transmission shaft 35. Through the first transmission shaft 34 and the second transmission shaft 35, the multiple first sprockets 31 and second sprockets 32 rotate synchronously, thereby enabling the multiple transmission chains 33 to rotate synchronously. Furthermore, the support members 4 on the multiple transmission chains 33 are correspondingly arranged to ensure they can collectively support the cigarette holder, thereby increasing the stability of the cigarette holder on the support member 4.

The base 1 of the electro-hydraulic push rod 214 is connected to the guide column 211 via the crossbeam 212, and its output end is connected to the support plate 22. When not in use, the height of the support plate 22 can be lowered using the lifting assembly 21, thereby reducing the overall height of the device and facilitating the placement of the cigarette holder. When loading cigarettes, the cigarette hanging rod can be placed in the bearing groove first, and then the height can be raised by the lifting component 21 so that the top of the transmission chain 33 is above the layer of cigarettes to be hung at a horizontal height, ensuring that the cigarette hanging rod can be raised above the layer of cigarettes.

[0041] Furthermore, a handrail 5 is provided on the guide column 211. The handrail 5 facilitates the adjustment of the position of the bracket 2, thereby facilitating the adjustment of the position and angle of the cigarette hanger. It also makes it easier to align the support groove 41 with the cigarette hanger when unloading cigarettes.
