Description

Feeding type seedling taking and planting integrated transplanting mechanism Technical Field The invention belongs to agricultural machinery, and mainly relates to a feeding type seedling taking and planting integrated transplanting mechanism for transplanting crop seedlings. Background The seedling transplanting of the dry-land crops mainly needs to complete the process of transplanting the seedlings to the field after the seedlings are taken out of the seedling tray, and the core mechanism of the dry-land crop transplanting machine mainly completes the procedures of seedling taking, seedling conveying and transplanting. At present, no matter in a field or a greenhouse, seedling transplanting operation is carried out, the types of transplanting machines for transplanting crop seedlings to the field are more, and the transplanting machine also has better operation effect, but the seedlings are usually put into the transplanting machines to be transplanted after being manually taken, and the types are the most common semiautomatic dry-land seedling transplanting machines in the market at present, and the efficiency of integral transplanting is seriously influenced due to manual seedling taking operation, and the operation quality is also difficult to guarantee. The full-automatic dry land transplanting machine at the present stage mainly has two working modes, namely, a transplanting mechanism is utilized to directly complete seedling taking, seedling conveying and seedling throwing transplanting operation, the seedling throwing transplanting process mainly comprises the steps of throwing the seedlings after seedling taking into a dug pit to complete planting, but the transplanting mechanism needs to dig the pit in advance, stable planting operation cannot be realized, only the seedling throwing and falling operation process can be calculated, and the operation requirement of planting on a dry mulching film cannot be realized, and the full-automatic dry land transplanting machine also comprises the steps of carrying out automatic seedling taking through the cooperation of the seedling taking mechanism and the seedling supplying mechanism, conveying and throwing the seedlings into another set of planting machinery, and then carrying out independent planting operation. Disclosure of Invention The invention aims at solving the problems of the prior art, and provides a feeding type seedling taking and planting integrated transplanting mechanism which combines the requirements of agricultural production operation, the seedling taking, conveying and planting procedures required by dry land seedling transplanting can be completed by adopting a set of planetary gear train rotating mechanism, and the transplanting work after membrane rupture and hole digging required by the membrane transplanting process can be realized, so that the stable seedling planting work is ensured, various procedures are completed by one mechanism, the purposes of integration and system simplification of dry land crop seedling transplanting are achieved, the completeness of pot seedling matrix is guaranteed, and the damage to the root of pot seedlings is reduced in the transplanting process.
