Seedling taking mechanism for automatic transplanter

Abstract

The invention provides a seedling taking mechanism for an automatic transplanter. The seedling taking mechanism mainly comprises an overturning mechanism, a seedling taking frame, an inserting and pulling mechanism and a seedling taking claw. The seedling taking mechanism uses a cylinder as a driver; the overturning mechanism turns over the seedling taking frame to a position right above a seedling bowl; the seedling taking claw is inserted into the seedling bowl under the action of the inserting and pulling mechanism and simultaneously, the seedling taking claw clamps the seedling bowl; thenthe seedling bowl is pulled out and then turned over to a seedling dropping position to drop seedlings. The invention has the advantage that the seedling taking mechanism for the automatic transplanter is simple in mechanism, high in success rate of seedling taking and seedling dropping and high in integral efficiency, and can be applied to the field of plug seedling automatic transplantation.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an automatic seedling picking device applied to an automatic transplanting machine for seedlings in plug trays. Background technique [0002] The planting method of vegetables is mainly transplanting. Transplanting can avoid natural disasters such as drought and freezing damage during the seedling period, and can make full use of light and heat resources. It has the effect of climate compensation, early maturity and increased production of crops. economic and social benefits. [0003] At present, there are semi-automatic and fully automatic transplanting machines on the market. The semi-automatic transplanting machine uses the planter to plant seedlings, but it needs to manually take the seedlings from the hole tray and throw the seedlings. This kind of transplanting machine is labor-intensive and efficient. Low. The seedling taking and planting of the automatic transplant...

Problems solved by technology

Among the relevant published patents, such as CN104782292A, a seedling-taking mechanism of a plug-in seedling transplanting machine is disclosed, which can realize the clamping and throwing action of seedling claws, but the mechanism's seedling-taking track is a closed duckbill shape, that is, the trajectory of inserting the seedling claws into the substrate and pulling out the substrate after clamping the seedlings is not the same straight line. When taking seedlings, it is easy to crush the seedlings in the pot. The quality of the seedling substrate is high, the success rate of seedlings is low, and it is easy to damage the seedlings.

In CN102960107A, the gantry type seedling picking device requires a large driving torque, cannot be loaded on an actual transplanting machine, and cannot meet the requirements applicable to various plug trays, and has a single application
