Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco drying racks, and specifically relates to a tobacco drying rack structure. Background Art

[0002] Tobacco leaf sun-drying is a tobacco leaf curing method that mainly regulates natural temperature and humidity to make tobacco leaves go through three stages of withering and discoloration, color fixation, and dry tendons to meet the quality requirements of sun-dried tobacco. The method of curing tobacco leaves outdoors mainly with the help of sunlight heat, or curing tobacco leaves by drying them first and then drying them is called "sun-drying", and the curing time is about 1 to 2 weeks. The method of curing tobacco leaves by natural drying using air convection indoors or in a drying shed is called "air-drying", and the curing time is about 3 to 5 weeks. The sun-dried tobacco produced in various places varies greatly in variety characteristics and curing techniques, and the quality characteristics of tobacco leaves are also different. The main types of sun-dried tobacco are sun-dried red tobacco, sun-dried yellow tobacco, spice tobacco, yellow flower tobacco, etc. The main types of air-dried tobacco are cigar wrapper tobacco, Maryland tobacco, burley tobacco, and local air-dried tobacco.

[0003] When drying tobacco, a drying rack is needed to spread the tobacco flat for sunlight exposure. For example, Chinese invention patent CN115191633A discloses a tobacco drying rack that pulls the circular block upward, so that the circular block drives the fixed rod to move upward, and at the same time stretches the spring, and then pulls the drying rod farthest from the storage structure (for the convenience of expression, the drying rod will be referred to as the end drying rod in the following text). As the distance between the drying rod and the storage structure increases, the rope gradually separates from the reel, and as the reel rotates, the torsion spring twists; when the slot blocks at both ends of the end drying rod move to the bottom of the fixed structure, the circular block is released, and the fixed rod moves downward under the action of the spring, and the lower end of the fixed rod is plugged into the slot on the top surface of the slot block. At this time, the end drying rod is restricted in position and cannot move freely. At this time, move other drying rods as needed, adjust the spacing between the drying rods as needed, and then lay the tobacco leaves neatly for drying; when the drying is completed and the tobacco leaves need to be collected, just pull up the two circular blocks at the same time to separate the two fixed rods from the slot block. Under the action of the torsion spring, the reel rotates and retracts the rope. At the same time, the end drying rod moves the remaining drying rods to one end close to the storage structure until all the drying rod assemblies can no longer move. At this time, the staff can remove the tobacco in a centralized manner without having to repeatedly change positions, thereby improving work efficiency. It should be noted that the diameter of the drying rod is smaller than the width of the slot block, so even if the drying rod assemblies are close together, it will not hinder the removal of the tobacco.

[0004] Although the above-mentioned prior art can conveniently place tobacco on the surface of the crossbar, after the tobacco is dried, it needs to be collected before new tobacco can be laid out for drying. The interval between collecting and drying is long, thereby reducing the drying efficiency. Utility Model Content
