Description

Technical Field

[0001] This utility model relates to the field of seedling lifting device technology, and in particular to a device that facilitates seedling lifting. Background Technology

[0002] In the early days, seedlings were manually lifted by hand using a seedling-lifting shovel during transplanting. Due to limited human strength, the lifting efficiency was slow, and manual operation could not ensure the integrity of the soil mound under the seedling, which was not conducive to the subsequent transportation and transplanting of seedlings. With the development of industrial technology, some simple seedling lifting devices have emerged, saving the step of manually shoveling seedlings and improving the efficiency of lifting seedlings. However, they cannot guarantee the integrity of the seedlings when they are taken out. The existing seedling lifting device has the problem that the seedlings cannot be fixed in place, causing them to tilt, which leads to the inability to guarantee the integrity of the seedlings and low lifting efficiency.
