Description

Technical Field

[0001] The utility model relates to the technical field of tobacco production, in particular to a tobacco leaf lifting mechanism in a tobacco flue-curing room. Background Art

[0002] In the field of tobacco production, intensive baking in the flue-curing room is the current advanced baking method. This method is to fix the fresh tobacco leaves in the flue-curing room with tobacco rods or tobacco clips, and then hang them in layers for intensive baking. Our company has developed and applied for a variety of tobacco clip collection and hanging equipment for flue-curing rooms, especially a tobacco clip conveying system for flue-curing rooms with application number 202222779868.9, which has a high market share, but because the conveyor is longer and requires a larger space, it is not applicable to old flue-curing rooms with smaller spaces. Therefore, for old flue-curing rooms, due to the small space, they still choose to hang tobacco leaves manually, which has low work efficiency.

[0003] Our company has an application number of 202222071994.9 for a lift truck used for loading and unloading tobacco leaves in a tobacco flue-curing room. The whole set of equipment is small and does not require a large rotating space. It is more suitable for old tobacco flue-curing rooms. However, the work platform needs to be lifted and lowered frequently to load and unload tobacco leaves. Not only is the work efficiency low, but the safety risk of the workers standing on the work platform will also increase. Utility Model Content

[0004] The purpose of the utility model is to provide a tobacco leaf lifting mechanism in a tobacco flue-curing room, which can be vertically arranged on the working platform of a lifting vehicle, thereby controlling the horizontal volume of the lifting mechanism to a great extent, and can be suitable for old tobacco flue-curing rooms. The lifting work of tobacco leaves does not require a working platform to lift and load and unload tobacco leaves.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a tobacco lifting mechanism in a tobacco flue-curing room, including a lifting car, two groups of connecting supports are relatively arranged on the working platform of the lifting car, guide rods and lifting rods are vertically slidably arranged on the connecting supports, and a lifting motor for driving the guide rods and lifting rods to move up and down is arranged on the connecting supports, and upper supporting rods and lower supporting rods are respectively arranged at the top and bottom ends of each group of guide rods and lifting rods, and driving sprockets and driven sprockets are respectively arranged at corresponding upper and lower positions of each group of upper supporting rods and lower supporting rods, a lifting chain is arranged between the driving sprocket and its corresponding driven sprocket, and a plurality of tobacco rack hanging feet and tobacco foot hanging feet are equidistantly and cross-arranged on the lifting chain.

[0006] Preferably, a slideway for moving the two groups of guide rods and lifting rods closer together and further apart is horizontally disposed on the connecting support, and a screw motor for driving the two groups of guide rods and lifting rods closer together and further apart is disposed on the connecting support.

[0007] Preferably, a sprocket main motor is horizontally arranged between the two lower support rods, one side output end of the sprocket main motor is transmission connected to one of the driving sprockets, and the other side output end of the sprocket main motor is transmission connected to the other driving sprocket through a retractable transmission shaft.

[0008] Preferably, the four vertically arranged guide rods and lifting rods are arranged on the connecting support in a rectangular shape as a whole.

[0009] Preferably, the horizontal heights of the cigarette rack hanging feet and the cigarette foot hanging feet on different lifting chains are staggered.

[0010] Preferably, the connecting support is fixed to the working platform of the lifting vehicle by means of positioning pins.

[0011] The beneficial effects of the utility model are:

[0012] 1. This solution vertically sets up an additional lifting mechanism on the working platform of the lifting vehicle, which greatly controls the horizontal volume of the lifting mechanism, can be applied to old tobacco flue-curing rooms, and the lifting work of tobacco leaves does not require the working platform to lift and unload tobacco leaves. It improves work efficiency and ensures the safety of the staff standing on the working platform.

[0013] 2. The connecting support is provided with a lifting motor for driving the guide rod and the lifting rod to move up and down. The lifting motor drives the guide rod and the lifting rod to move up and down relative to the working platform. The height of the lower support rod from the ground can be adjusted instantly, and is not affected by the change of different levels of the working platform each time, which is convenient for hanging cigarette clamps.

[0014] 3. Multiple tobacco rack hanging feet and cigarette foot hanging feet are equidistantly arranged on the lifting chain. The horizontal heights of the tobacco rack hanging feet and cigarette foot hanging feet on different lifting chains are staggered. It is convenient to hang the tobacco clips at an angle. Since the tobacco clips and tobacco leaves are large in size, they are hung horizontally and occupy a large space. They are not suitable for old tobacco curing rooms. Such a setting can reduce the space occupied by tobacco leaf lifting.

[0015] 4. As the space of the old tobacco flue-curing room is small, the position of the tobacco clip transporting equipment is not easy to adjust, and it is difficult to align it with the tobacco lifting mechanism. The screw motor controls the horizontal position of the two lifting chains to actively adapt to the position of the tobacco clip transporting equipment. This reduces the difficulty of aligning the tobacco clip transporting equipment with the tobacco lifting mechanism. BRIEF DESCRIPTION OF THE DRAWINGS
