Description

Technical Field

[0001] This utility model relates to auxiliary equipment for tobacco curing, and in particular to a rapid tobacco loading and unloading device for a stepped tobacco curing barn. Background Technology

[0002] Loading and unloading tobacco in the tobacco curing barn is a crucial step in the tobacco curing process. Loading involves hanging tobacco-woven rods or clips (collectively referred to as tobacco-weaving tools) onto the tobacco rack beams in the barn. Unloading occurs after the tobacco leaves have dried and regained moisture, removing the tobacco-weaving tools from the rack beams. Tobacco racks come in three-tiered and four-tiered configurations. In a three-tiered rack, the second and third beams are relatively high, while in a four-tiered rack, the third and fourth beams are also relatively high. Tools are required for both loading and unloading. There are two existing types of tobacco loading and unloading tools. One type is directly fixed inside the tobacco curing barn, which provides good continuity of loading, but the environment inside the tobacco curing barn is humid and hot, resulting in a shorter service life. In addition, it is bulky and cannot be used flexibly in other tobacco curing barns, and the cost of matching tobacco curing barns with the equipment and investing in the machine is high. The other type is mobile, which can be used flexibly in various tobacco curing barns and has a low cost, but the continuity of loading and unloading is poor and the efficiency of loading and unloading is low. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a stepped tobacco curing barn rapid tobacco loading and unloading device, which has good continuity and high efficiency in tobacco loading and unloading, can be flexibly used in various tobacco curing barns, and has low cost and low modification cost.

[0004] The objective of this utility model is achieved through the following technical solution: A stepped tobacco curing barn rapid loading and unloading device includes a lifting frame. The lifting frame includes two stepped lifting rods arranged in a mirror image. The opposing horizontal lifting rods of the two lifting rods respectively support both ends of a tobacco clamping tool containing tobacco leaves. A transport frame is movably installed within the lifting frame. The transport frame includes two stepped transport rods arranged in a mirror image. The transport horizontal and vertical rods of the two transport rods are one-to-one opposite to the supporting horizontal and vertical rods of the two lifting rods. The horizontal transport bar can respectively support both ends of the tobacco leaf clamping tool with tobacco leaves clamped on it. It also includes a drive mechanism, which drives the transport frame to move along a rectangular motion trajectory. Each time the transport frame moves along the rectangular motion trajectory once, each transport horizontal bar transports the tobacco leaf clamping tool with tobacco leaves clamped on each supporting horizontal bar to the next adjacent supporting horizontal bar and / or tobacco beam, or transports the tobacco leaf clamping tool with tobacco leaves clamped on each supporting horizontal bar and / or tobacco beam to the next adjacent supporting horizontal bar.

[0005] Furthermore, the drive mechanism includes a linear motion mechanism and a lifting motion mechanism. The linear motion mechanism is parallel to the lifting horizontal bar. One end of the linear motion mechanism is connected to the lifting frame, and the other end is connected to the lifting motion mechanism. The lifting motion mechanism is parallel to the vertical bar of the lifting rod, and the end of the lifting motion mechanism is connected to the transport frame.

[0006] Furthermore, the linear motion mechanism and the lifting motion mechanism are connected to a controller.

[0007] Furthermore, a sliding structure is connected between the linear motion mechanism and the lifting motion mechanism, and the sliding structure is slidably mounted on the lifting frame.

[0008] Furthermore, it also includes a base, and a lifting device is connected between the base and the bottom of the support frame.

[0009] Furthermore, the base is equipped with movable rollers.

[0010] Furthermore, the lower ends of the two lifting rods are detachably connected to extended lifting rods, which are stepped. The lower ends of the two transport rods are also detachably connected to extended transport rods, which are stepped. The horizontal and vertical transport rods of the extended transport rods are aligned with the horizontal and vertical lifting rods of the extended lifting rods.

[0011] Furthermore, the high end of the transport rack is equipped with a first detector that can detect tobacco leaves on nearby tobacco beams, and the first detector is connected to a controller.

[0012] Furthermore, the lower end of the transport frame is equipped with a second detector that can detect the tobacco leaf clamping tool on the lowest lifting horizontal bar, and the second detector is connected to the controller.

[0013] Furthermore, the tobacco beam is equipped with a track, and the two ends of the tobacco leaf clamping tool are equipped with rollers that can roll on the track.

[0014] The beneficial effects of this utility model are: The stepped tobacco curing barn rapid loading and unloading device proposed in this utility model has a drive mechanism that drives the transport frame to move along a rectangular motion trajectory. Each time the transport frame moves along the rectangular motion trajectory, each transport horizontal bar moves the tobacco leaf clamping tool with tobacco leaves on each lifting horizontal bar to the next adjacent lifting horizontal bar and / or tobacco beam, or moves the tobacco leaf clamping tool with tobacco leaves on each lifting horizontal bar and / or tobacco beam to the next adjacent lifting horizontal bar. This realizes the loading and unloading of tobacco into or from the upper tobacco beams of the tobacco curing barn, with good continuity and high efficiency, and can be flexibly used in various tobacco curing barns.

[0015] The linear motion mechanism and the lifting motion mechanism work together to make the transport frame move along a rectangular motion trajectory.

[0016] When loading and unloading tobacco on the second layer of the three-layer tobacco rack, the lifting device lowers to its lowest point, and the distance between the lower end of the two lifting rods and the ground is suitable for the tobacco leaf clamping tool. When loading and unloading tobacco on the third layer of the three-layer tobacco rack, the lifting device rises to a certain height, suitable for a person to stand on the ground and place the tobacco leaf clamping tool with tobacco leaves on the lower end of the lifting rod.

[0017] The base is equipped with casters to facilitate the movement of the smoke loading and unloading device.

[0018] By adding extended lifting rods and extended transport rods, the tobacco loading and unloading device is suitable for loading and unloading tobacco on the top layer of a four-layer tobacco rack. At this time, the lifting device rises to a certain height, which is suitable for a person to stand on the ground and place the tobacco leaf clamping tool with tobacco leaves clamped on the horizontal lifting rod at the lower end of the extended lifting rod.

[0019] During the loading and unloading of tobacco, when the first detector detects tobacco leaves for a certain period of time, the controller stops the drive mechanism. Similarly, during unloading, when the second detector detects tobacco leaf clamping tools for a certain period of time, the controller stops the drive mechanism to prevent the clamping tools with tobacco leaves from clustering together.

[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0031] Example 1 like Figure 1-3The stepped tobacco curing barn rapid loading and unloading device shown includes a lifting frame 1, which includes two stepped lifting rods 2 arranged in a mirror image. Each lifting rod 2 is composed of multiple horizontal lifting rods and multiple vertical rods connected alternately. The lower end of the lifting rod 2 is the rear end, and the upper end is the front end. The opposing horizontal lifting rods of the two lifting rods 2 respectively support the two ends of the tobacco leaf clamping tool 19 with tobacco leaves. A transport frame 3 is movably installed inside the lifting frame 1. The transport frame 3 includes two stepped transport rods 4 arranged in a mirror image. Each transport rod 4 is composed of multiple horizontal transport rods and multiple vertical rods connected alternately. The horizontal and vertical transport rods of the two transport rods 4 are one-to-one opposite to the horizontal and vertical lifting rods of the two lifting rods 2. The opposing horizontal transport rods of the two transport rods 4 can respectively support the two ends of the tobacco leaf clamping tool 19 with tobacco leaves. It also includes a drive mechanism that drives the transport frame 3 to move along a rectangular trajectory. The drive mechanism for achieving this rectangular trajectory includes a linear motion mechanism 5 and a lifting motion mechanism 6. The linear motion mechanism 5 is parallel to the lifting horizontal bar. One end of the linear motion mechanism 5 is fixedly connected to the front end of the lifting frame 1, and the other end is fixedly connected to a sliding structure 7. The sliding structure 7 is slidably mounted on the lifting frame 1. There are many structural forms of the sliding structure 7 and various ways to achieve this sliding mounting. For example, the sliding structure 7 can be a flat frame with sliders 8 on both sides, and the lifting frame 1 has matching grooves 9 on both sides. The lifting structure 7 has a lifting motion mechanism 6, which is parallel to the vertical bar of the lifting rod 2. The end of the lifting motion mechanism 6 is connected to the bottom of the transport frame 3. The linear motion mechanism 5 can be of various types, such as a telescopic rod, and the lifting motion mechanism 6 can be of various types, such as a telescopic rod, a gear rack, etc. The linear motion mechanism 5 and the lifting motion mechanism 6 are connected to a controller. Each time the transport frame 3 moves along a rectangular trajectory, each transport horizontal bar moves the tobacco leaf clamping tool 19, which is attached to the tobacco leaf, from the lifting horizontal bar to the next adjacent lifting horizontal bar and / or tobacco beam 16, or moves the tobacco leaf clamping tool 19, which is attached to the lifting horizontal bar and / or tobacco beam 16, to the next adjacent lifting horizontal bar. There should be a certain space between the left and right sides of the lifting frame 1. This space should be sufficient to accommodate the transport frame 3 and the tobacco leaf clamping tool 19, and facilitate the movement of the transport frame 3 under the drive of the drive mechanism, or the movement of the tobacco leaf clamping tool 19. There are various specific structural forms of the lifting frame 1, which will not be described in detail here. Similarly, there should be a certain space between the left and right sides of the transport frame 3, which should be sufficient to accommodate the tobacco leaf clamping tool 19, and facilitate the movement of the transport frame 3 under the drive of the drive mechanism, or the movement of the tobacco leaf clamping tool 19. There are various specific structural forms of the transport frame 3, which will not be described in detail here.A base 10 is provided below the lifting frame 1, and a lifting device 11 is provided between the bottom of the lifting frame 1 and the base 10. The lifting device 11 has various structural forms, such as four telescopic rods respectively set at the four corners of the base 10. The base 10 is provided with moving rollers 12, which makes the smoke loading and unloading device easy to move.

[0032] In this embodiment, when used in a three-layer tobacco hanging rack tobacco curing barn, the device is moved to the entrance of the curing barn via the moving rollers 12, ensuring that the front end of the loading and unloading device faces the entrance. When loading tobacco onto the second-layer tobacco beam 16, the height of the lifting frame 1 is adjusted via the lifting device 11, so that its upper end approaches the second-layer tobacco beam 16 from below. The drive mechanism is then activated, causing the transport frame 3 to... Figure 7-10 The transport frame 3 moves along a rectangular trajectory, placing tobacco leaf clamping tools 19, which are clamped with tobacco leaves, onto the two horizontal lifting bars at the lower end of the lifting frame 1. Each time the transport frame 3 moves along the rectangular trajectory, each horizontal lifting bar moves the tobacco leaf clamping tools 19 from their respective lifting bars to the next adjacent lifting bar and / or tobacco beam 16. The tools are then lifted onto the tobacco beam 16 and moved to a designated position using a lifting rod, thus loading the tobacco. When unloading tobacco from the second layer tobacco beam 16, the height of the lifting frame 1 is adjusted using the lifting device 11, so that its upper end approaches the second layer tobacco beam 16 from below. The drive mechanism is then activated, causing the transport frame 3 to move along the rectangular trajectory. Figure 11-15 The transport frame 3 moves along a rectangular trajectory, using a lifting rod to lift the tobacco-clamping tools 19, which are attached to the tobacco leaves on the tobacco beam 16, to the high end of the lifting frame. Each time the transport frame 3 moves along the rectangular trajectory, it moves the tobacco-clamping tools 19 from each lifting horizontal bar and / or the tobacco beam 16 to the next adjacent lifting horizontal bar. When loading or unloading tobacco onto or from the third layer of tobacco beam 16, the height of the lifting frame is adjusted by the lifting device 11 so that its high end is close to the lower side of the third layer of tobacco beam 16. This allows a person to stand on the ground and place or remove the cured tobacco-clamping tools 19 from the lower lifting horizontal bar. This embodiment achieves good continuity and high efficiency in loading and unloading tobacco onto or from the high-level tobacco beam 16 of the tobacco curing barn, and can be flexibly used in various tobacco curing barns.

[0033] Example 2 like Figure 4As shown, the difference from Embodiment 1 is that: The lower ends of the two lifting rods 2 are detachably connected to extended lifting rods 13. There are many ways to detach and connect them, such as connecting a vertical first connecting rod to the lower side of the end of the upper horizontal lifting rod of the extended lifting rod 13. The first connecting rod and the vertical rod of the lifting rod 2 have corresponding through holes, and the first connecting rod and the vertical rod of the lifting rod 2 are connected by bolts passing through the corresponding through holes. The extended lifting rod 13 is stepped, meaning it is composed of multiple horizontal and vertical lifting rods connected in an alternating manner, and the two extended lifting rods 13 are mirror images of each other. The lower ends of the two transport rods 4 are detachably connected to extended transport rods 14. There are many ways to detach and connect them, such as connecting a vertical second connecting rod to the lower side of the end of the upper horizontal transport rod of the extended transport rod 14. The second connecting rod and the vertical rod of the transport rod 4 have corresponding through holes, and the second connecting rod and the vertical rod of the transport rod 4 are connected by bolts passing through the corresponding through holes. The extended transport rod 14 is stepped, meaning that the extended transport rod 14 is composed of multiple horizontal and vertical transport rods connected in an alternating manner, and the horizontal and vertical transport rods of the extended transport rod 14 are opposite to the horizontal and vertical support rods of the extended lifting rod 13.

[0034] When this embodiment is used in a four-layer tobacco curing barn, when loading or unloading tobacco from the third layer tobacco beam 16, refer to Embodiment 1. When loading or unloading tobacco from the fourth layer tobacco beam 16, an extended lifting rod 13 is connected to the two lifting rods 2, and an extended transport rod 14 is connected to the two transport rods 4. The height of the lifting frame 1 is adjusted by the lifting device 11 so that its high end is close to the fourth layer tobacco beam 16 from below. At this time, it is suitable for a person to stand on the ground and place the tobacco leaf clamping tool 19 with tobacco leaves clamped on it to the lower lifting horizontal bar or to take the tobacco leaf clamping tool 19 with tobacco leaves clamped on it from the lower lifting horizontal bar.

[0035] Example 3 The difference from Example 1 is as follows: The high front side of the transport frame 3 is provided with a first detector 15 that can detect tobacco leaves on the nearby tobacco beam 16, and the top of the low transport horizontal bar of the transport frame 3 is provided with a second detector that can detect tobacco leaf clamping tool 19 on the lowest lifting horizontal bar. The first detector 15 and the second detector are distance detectors.

[0036] During the loading and unloading of tobacco, when the first detector 15 detects tobacco leaves for a certain period of time, the controller stops the drive mechanism. Similarly, during unloading, when the second detector detects tobacco leaf clamping tools 19 for a certain period of time, the controller stops the drive mechanism to prevent the tobacco leaf clamping tools 19 from clumping together.

[0037] Example 4 like Figure 5-6As shown, the difference from Embodiment 1 is that: a track 17 is provided on the tobacco beam 16, and rollers 18 that can roll on the track 17 are provided at both ends of the tobacco leaf clamping tool 19, facilitating the movement of the tobacco leaf clamping tool 19 along the track 17 when it is lifted with a lifting pole. Baffles 20 are provided at 5cm positions at both ends of the tobacco leaf clamping tool 19 to prevent damage to the tobacco leaves due to friction when the tool moves along the track 17. Grooves are provided on each transport horizontal bar and each lifting horizontal bar, and the ends of the tobacco leaf clamping tool 19 are located within these grooves to prevent them from falling off.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
