Description

Technical Field

[0001] The utility model relates to the technical field of seedling transplanting, in particular to an adjusting mechanism of a seedling transplanting supporting device. Background Art

[0002] Seedlings are young plants in the early stage of growth after seeds germinate. Planting and managing seedlings uniformly can save a lot of planting time and increase the survival rate of seedlings, so this method is widely used in forestry and agriculture. However, when the seedlings grow to a certain size, they need to be transplanted. At this time, the seedlings need to be dug out from the soil where they originally grew. This behavior is called transplanting.

[0003] Chinese patent CN216362539U discloses a seedling transplanting device, which discloses a technical solution with high stability, solving the problem that although the existing transplanting device has the advantages of automatic digging and transplanting, the external threaded cavity interacts with the ground when rotating, and the internal threaded sleeve and the trolley are not fixed, which easily causes the transplanting device to shift as a whole, posing a risk of damaging the seedlings.

[0004] When the device is in use, an arc-shaped fixing plate is inserted into the ground to support the transplanting device to prevent deviation. However, the movable frame supports it through rollers. When the motor rotates and drives the arc plate to move downward through a threaded connection, it is easy to cause the movable seat to shake, thereby causing the movable seat to move, reducing the use effect. Therefore, an adjustment mechanism of a seedling transplanting support device is proposed to solve the above problem. Utility Model Content
