Technical Field

[0001] This utility model relates to the field of transportation protection technology, specifically a protective device for transporting lettuce seedlings. Background Technology

[0002] In the process of vegetable seedling cultivation, seedling raising is necessary. Farmers often encounter situations that lead to large-scale seedling death and only a few strong seedlings. Consider this situation: not only is the seed wasted, but it also affects the planting of the next crop. Such professional seedling organizations cultivate vegetable seedlings and then sell them to farmers for planting.

[0003] According to the search (application number: 202321710583.8), a vegetable seedling transportation protection device is provided, including a protective sleeve and a protective base plate connected to one side of the protective sleeve. The protective sleeve has an opening, and the protective base plate is connected to a plurality of culture tubes corresponding to the opening. One end of the sleeve away from the protective sleeve is connected to a second sleeve. A connecting component is provided at the connection between the protective sleeve and the protective base plate. The connecting component includes an adjustable connecting frame.

[0004] In the process of realizing this utility model, the inventors found that the following problems in the prior art have not been solved: Although the device is equipped with a corresponding sliding lifting component and a threaded fixing component on one side of the protection mechanism, which can prevent the cover from opening and hitting the lettuce seedlings and causing damage, the sliding lifting component and the threaded fixing component have high manufacturing and maintenance costs, and disassembly and assembly depend on tools. At the same time, they occupy a lot of space and urgently need to be improved. Therefore, we propose a lettuce seedling transportation protection device. Utility Model Content
