Description
Technical field
The invention belongs to the technical field in talents for agri-mechanization transplanter, more particularly to a kind of riding type transplanter to have
The ground-contour-following device of multirow planting mechanism.
Background technology
Culturing and transplanting seedlings can not only shorten growth cycle, improve land utilization ratio, can also reduce labour, reduce production
Cost etc., it is known that it has, and considerable Social benefit and economic benefit is equal, and at present, the transplanter that the country develops mainly has flexibility
Disc type, suppending cup type, chain-clip type, seedling guide tube type etc..With the development of modernization, bowl transplantation of seedlings demand can be increasingly
More, transplanter gradually can also be developed from semi-automation to full-automatic transition, and it is the development of transplantation technique to ensure transplanting quality
Premise.
For transplantation technique, one link of most important of which is to transplant planting seedlings for part, as transplanting process
