Description

Technical Field

[0001] This utility model belongs to the field of planting machine technology, and specifically relates to a multi-functional planting machine. Background Technology

[0002] A transplanter is a planting machine that can plant seedlings according to certain agronomic requirements. The most common types include: seedling guide tube transplanters, duckbill transplanters, and hanging cup transplanters. Each of these transplanters has its own characteristics and is suitable for different crops and operational needs.

[0003] Current planting machines have relatively limited functionality and cannot complete all basic tasks in one go, therefore functional upgrades and improvements are needed. In addition, there are many different mechanisms in the duckbill planting assembly of the duckbill planter. The most common one is the linkage duckbill planting assembly, such as the patent "CN115136776A discloses a vegetable transplanter and its duckbill planting device", which uses a linkage mechanism to drive the reciprocating motion. However, the structure of the above patent is relatively complex, and it is more troublesome to produce and assemble. The most important point is that the duckbill opening and closing control lever of the gate cable is directly set on the cam, which is likely to get tangled and is not easy to implement.
