Description

Technical Field

[0001] This utility model relates to the field of transplanting device technology, and in particular to a rapid transplanting device for *Polygonatum yunnanense* seedlings. Background Technology

[0002] Transplanting of plant seedlings is a common practice in agricultural planting techniques. After the seedlings have been cultivated in the early stage, they need to be transplanted. At this time, a special transplanting device is required for transplanting. There are various types of transplanting devices, and different transplanting devices can be selected according to the actual planting needs.

[0003] Existing seedling transplanting equipment requires manual labor to insert the shovel head into the ground to widen the hole, which requires considerable physical effort on dry, hard soil. Utility Model Content

The lower seedling guide tube passes through the outside of the motor compartment and is rotatably connected to the motor compartment. A hollow drill bit is fixedly connected to the end of the lower seedling guide tube.

[0010] Preferably, the hollow drill bit has a seedling outlet channel, and the upper seedling guide tube, the hollow output shaft of the hollow shaft motor, the lower seedling guide tube, and the seedling outlet channel are connected in sequence.

[0011] In the above scheme, the hollow shaft motor drives the drill bit to realize the integrated drilling and seedling guiding, which greatly reduces the operation time per plant and improves efficiency. The spiral soil guide groove increases the soil discharge rate and avoids repeated hole cleaning.

[0012] Preferably, the outer wall of the lower guide tube is provided with threads, and the middle of the pedal has a threaded groove.

[0013] In the above scheme, the pedal can be adjusted in height by rotating a spiral on the lower guide tube to accommodate operators of different heights. At the same time, the pedal can also serve as a limiting plate to control the drilling depth. Furthermore, stepping on the pedal during drilling can increase the stability of the drilling and prevent the hollow drill bit from deviating.

[0014] Preferably, the hollow drill bit has a spiral soil guide groove on its surface, the inner diameter of the drill bit is the same as the inner diameter of the lower seedling guide tube, a connecting pipe is provided at the top of the hollow drill bit, and bolt holes are opened on the outer wall of the connecting pipe. The connecting pipe is fixedly connected to the lower seedling guide tube by bolts.
