Description

TECHNICAL FIELD

[0001] The utility model relates to an automatic lifting tobacco hanging frame and belongs to the tobacco baking hanging tobacco operation technical field. BACKGROUND

[0002] Most of the current tobacco curing barns are large-scale intensive curing barns. Large-scale intensive curing barns can accommodate more tobacco for baking, and have the advantages of large tobacco loading capacity, precise control, and energy saving, distinguishing them from small-scale intensive curing barns and small-scale ordinary curing barns. To reduce the labor cost of tobacco farmers, tobacco clamps are used for tobacco baking in large-scale intensive curing barns, and now tobacco clamps account for more than 48% of the total baking barns.

[0003] During the baking process, most current large-scale intensive curing barns have three or four layers of tobacco shelves. In a three-layer large-scale intensive curing barn, the third layer (counted from the bottom up) is 3.3m high; in a four-layer large-scale intensive curing barn, the fourth layer is 3.7m high and the third layer is 2.9m high. During the process of loading fresh tobacco, the loading personnel need to work at a height of 2.9m or above, which can easily lead to a fall from a high place and cause safety accidents.

[0004] The existing document (CN215837051U) discloses a lifting type tobacco shelf for use in a curing barn, comprising: a lifting mechanism, including a base, multiple levels of telescopic cylinders, and hooks, the outer shell of the multiple levels of telescopic cylinders is vertically fixed to the base, and the hooks are provided on the outer side of the upper part of the outer shell of the multiple levels of telescopic cylinders and the outer side of the upper part of each level of telescopic cylinders; a support beam that can be arranged on the hooks; and tobacco hanging rods that can be arranged on the support beam. This tobacco shelf can realize fast tobacco loading and unloading operations, and does not need to install traditional fixed tobacco shelves in the curing barn, and can be flexibly assembled and used. However, the applicant found in actual application that this tobacco shelf still needs to be manually moved to different positions for loading and unloading tobacco, and the work efficiency still needs to be improved.
