Transplanting mechanism for hole formation and seedling taking of rapeseed carpet seedlings and transplanting method thereof

Abstract

The invention discloses a transplanting mechanism for hole formation and seedling taking of rapeseed carpet seedlings and a transplanting method thereof. An existing rapeseed carpet seedling transplanting machine cannot achieve seedling taking and seedling planting through one set of mechanism. A planting arm includes a seedling throwing cam, a hole formation cam, a shifting fork, a hole formationrod, a seedling pushing rod, a seedling needle, a hole formation knife and a planting arm shell; when the planting arm runs to the positions of rapeseed carpet seedlings, and the seedling needle catches the seedlings from the rapeseed carpet seedlings; when the planting arm runs to a seedling throwing position, the hole formation cam runs to a push stage, and the hole formation knife swings to beparallel to the seedling needle under driving of the hole formation rod; at the moment, the hole formation knife is used for hole formation on the ground; after hole formation, the push stage of thehole formation cam is over, the hole formation knife returns to an initial position, at the moment, the seedling throwing cam runs to a push stage, the shifting fork drives the seedling pushing rod tomove forwards to push the seedlings clamped by the seedling needle out, the seedlings fall in the holes formed by the hole formation knife, and then transplanting is completed. According to the transplanting mechanism, seedling taking, conveying, hole formation and transplanting can be completed through one set of mechanism.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a mechanism for opening holes for rape blanket seedlings, picking seedlings and transplanting them and a transplanting method thereof. Background technique [0002] my country has always been a big country for growing rapeseed, but for a long time, rapeseed has been transplanted manually, which is labor-intensive. Although there are transplanting machines for rape at the present stage, most of the transplanting machines are not efficient, the overall structure is complex, and the cost is relatively high, which is inconsistent with the basic national conditions of my country's agriculture. Rapeseed blanket seedling transplanting technology is a transplanting technology with high efficiency, simple structure and cost saving. Transplanting rapeseed blanket seedlings can not only greatly improve the transplanting efficiency, but also help to expand the rape...

AI Technical Summary

Problems solved by technology

[0003] The transplanting of rapeseed blanket seedlings needs to complete the complicated transplanting process such as blanket seedling clamping, transportation, hole opening and planting. The existing rapeseed blanket seedling transplanting machinery cannot realize the process of taking seedlings and planting seedlings simultaneously with one mechanism. Most rapeseed blanket seedlings The seedling transplanting machine is modified on the basis of the rice blanket seedling transplanting machine. Multiple devices are used to complete a single operation. Seedlings, poor planting effect, unreliable operation, etc.
