Description

Technical Field

[0001] The utility model relates to the technical field of tobacco production, in particular to a tobacco leaf loading and unloading device 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.

[0004] In addition, the existing lifting equipment for loading and unloading tobacco leaves in the tobacco flue-curing room generally requires the staff to manually control the travel switch to drive the lifting equipment to rise and fall again after each loading and unloading of tobacco leaves. The degree of intelligence is low and the working efficiency of loading and unloading tobacco leaves is reduced. Utility Model Content

[0005] The utility model aims to provide a tobacco leaf loading and unloading device in a tobacco flue-curing room. When the tobacco leaves are hung up, the dead weight of the tobacco leaves is used to trigger the travel switch. When the tobacco leaves are taken down, the spring rebound force is used to release the travel switch. This eliminates the need for manual control of the lifting equipment, improves the degree of intelligence and the work efficiency of loading and unloading tobacco leaves.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a tobacco leaf loading and unloading device in a flue-cured tobacco room, comprising a lifting vehicle, a base is horizontally arranged on the working platform of the lifting vehicle, a linear track is horizontally arranged on the base, a frame sliding above the linear track is vertically arranged, an upper crossbeam is horizontally arranged just above the linear track, one end of the upper crossbeam is fixedly connected to the side wall of the frame, a tobacco clamp hanger is horizontally arranged between the upper crossbeam and the linear track, a wire reel is arranged on the frame, two pulleys are arranged on the upper crossbeam, and the steel of the wire reel is The wires are connected to the top of the cigarette clamp hanger after passing through two pulleys respectively; the upper crossbeam includes an upper crossbeam body and a rotating member, the rotating member is rotatably connected to the upper crossbeam body at one end away from the frame, a travel switch is provided on the upper crossbeam body, a trigger component of the travel switch is provided between the rotating member and the upper crossbeam body, one of the pulleys is provided on the rotating member, the rotating member and the top of the upper crossbeam body are both provided with bosses, the two bosses are connected by a spring, the spring is used to trigger the travel switch when tobacco leaves are hung on the cigarette clamp hanger, and release the travel switch after the cigarette clamp hanger is removed.
