Description

Technical Field

[0001] The utility model relates to the technical field of tobacco leaf cutting at the seedling stage, and specifically relates to a tobacco seedling leaf cutting device. Background Art

[0002] my country is the country with the largest tobacco production in the world, with a planting area of ​​more than 20 million mu. In the process of tobacco seedling cultivation, leaf cutting is an indispensable part of cultivating strong seedlings. At present, tobacco producing areas generally adopt intensive floating seedling cultivation. Because the floating seedling tray has many small holes, the growth space of tobacco seedlings is limited. When 5-7 leaves grow, the leaves of adjacent tobacco seedlings compete to obtain more light area and grow rapidly, while the roots and stems of tobacco seedlings grow slowly. If leaf cutting is not carried out in time, it is easy to form tall stem seedlings with poor plant shape and unsuitable for transplanting. Therefore, leaf cutting in the tobacco seedling stage is an indispensable measure for strengthening and hardening the seedlings in the process of tobacco seedling cultivation.

[0003] During the tobacco seedling raising process, the tobacco seedlings need to be trimmed many times, and the length of the cut leaves is different each time. The leaf cutters under the existing technology are mainly designed for highly standardized greenhouses. The equipment in the greenhouses is relatively easy to control, but the greenhouse seedling raising facilities in the mountainous areas of Guizhou are not perfect. The seedling raising sheds are relatively simple, and many of them are temporary. It is impossible to install electric adjustable leaf cutters. Manual leaf cutters are also sold, but it is difficult to control the cutting length and force when cutting leaves. Therefore, a more convenient, controllable and easy-to-carry tobacco seedling leaf reducer is needed. Utility Model Content
