Description

Technical Field

[0001] The invention belongs to the technical field of tobacco leaf fixing, and in particular relates to a rotating telescopic tobacco leaf penetrating rod device. Background Art

[0002] At present, the fresh tobacco leaves picked by tobacco farmers need to be baked in a curing room. The picked fresh tobacco leaves go through the yellowing period, the dry leaf period, and the dry tendon period before finally being made into finished tobacco. For baking tobacco leaves in a curing room, the traditional operation method is to use ropes and bamboo poles or other fixings for fixing tobacco leaves to braid and fix the tobacco leaves, that is, to tie and fix the fresh tobacco leaves on the tobacco rods and hang them in the curing room for baking.

[0003] For the traditional weaving of fresh tobacco leaves, only one person can operate for one tobacco stem, and multiple people cannot operate at the same time to weave the tobacco leaves and tie them to the tobacco stem. This is time-consuming and labor-intensive and cannot be applied to high-yield flue-cured tobacco work.

[0004] Secondly, when the tobacco leaves are tied and fixed on the tobacco stems with traditional ropes, as they are roasted, the fresh tobacco leaves will gradually dry out, which can easily cause the tied and fixed tobacco leaves to loosen, causing the roasted tobacco leaves to fall, resulting in waste and economic losses.

[0005] In addition, the traditional bundling method will use a large number of fixing rods and ropes. Long-term use will easily lead to aging of the ropes and fixing rods (such as bamboo poles or wooden poles), which are not convenient for reuse, and correspondingly easily cause waste of resources and increase the cost of tobacco farmers to flue-cure tobacco.

[0006] Therefore, in view of the technical problems that the traditional method of using ropes to tie fresh tobacco leaves to the tobacco rods is time-consuming and labor-intensive, easily causes the roasted tobacco leaves to fall, is inconvenient to reuse, and easily causes waste of resources, it is urgent to design and develop a rotating and telescopic tobacco rod threading device. Summary of the invention

[0007] The purpose of the present invention is to provide a rotating and telescopic tobacco leaf piercing rod device.

[0008] The object of the present invention is achieved as follows: the device comprises: a through-rod load-bearing housing, in which a first load-bearing rod and a first rotating rod coaxially rotating with the first load-bearing rod are arranged; a second load-bearing rod is arranged parallel to the first load-bearing rod, and a second rotating rod coaxially rotating with the second load-bearing rod; the first load-bearing rod and the second load-bearing rod are fixedly connected by a fixing column;

[0009] At least one perforation is arranged on the side of the load-bearing shell of the penetration rod; at least one tobacco leaf penetration needle is arranged on one side of the first rotating rod or the second rotating rod; the tobacco leaf penetration needle rotates and retracts along the perforation.

[0010] The present invention uses a first rotating rod that rotates coaxially with the first load-bearing rod, and a second rotating rod that rotates coaxially with the second load-bearing rod; combined with a tobacco threading needle arranged on one side of the first rotating rod or the second rotating rod, the perforation rotation and extension along the side of the threading rod load-bearing shell can be realized. For the same tobacco threading rod, multiple people can operate to weave tobacco leaves at the same time, and the falling of tobacco leaves during the tobacco baking process is eliminated. In addition, the tobacco threading rod of the present invention can be reused, avoiding waste of resources and reducing the cost of tobacco farmers to bake tobacco. BRIEF DESCRIPTION OF THE DRAWINGS
