Pneumatic row-by-row seedling picking device of pot seedling transplanter

Abstract

The invention provides a pneumatic row-by-row seedling picking device of a pot seedling transplanter. The device can realize the action of picking seedlings row by row; seedling picking and seedling throwing opportunities of a picking and throwing device are controlled by an air cylinder; and a needed seedling taking track is formed by the swinging of a large portal frame and the movement of one end of a small portal frame along a groove, and seedling picking and seedling throwing actions are realized by combining the control of the picking and throwing device.

Description

technical field [0001] The invention belongs to the field of automatic transplanting in facility agriculture, and relates to an automatic seedling picking device applied to an automatic transplanting machine for seedlings in pots and pots. Background technique [0002] Plug seedling cultivation is a new industry, and it is a new type of seedling cultivation technology developed internationally in the 1970s. Compared with conventional seedling cultivation methods, plug seedling cultivation has labor-saving, labor-saving, fast seedling growth, resource saving, With the advantages of low cost, high efficiency, easy management and protection of the agricultural ecological environment, it is mainly used in the cultivation of tobacco, flowers, vegetables and trees. There are a series of links in plug seedling cultivation, from seeding to transplanting. The transplanting of seedlings is a low-efficiency, monotonous and repetitive action, but it requires a lot of manual work. The se...

Problems solved by technology

There are a series of links in plug seedling cultivation, from seeding to transplanting. The transplanting of seedlings is a low-efficiency, monotonous and repetitive action, but it requires a lot of manual work. The seedlings are transferred from the plug to the semi-automatic transplanting machine. It is easy to get tired at work, the production efficiency is low, and it is easy to miss out. It is particularly critical whether the transplanting of plug trays can achieve automatic high speed.

[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, while the seedling taking and planting of the automatic transplanting machine are all done automatically by machinery. There must be a coordinated action of clamping and releasing seedlings, which puts forward higher requirements for the design of the automatic seedling picking mechanism

Among the relevant published patents, such as patent CN101940102A, a seedling-taking mechanism of a plug-in seedling transplanting machine is disclosed, which can realize the clamping and throwing action of the seedling-taking claws, but the seedling-taking track of this mechanism is a closed duck Mouth-shaped, 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. It is easy to crush the seedlings when taking seedlings. The quality of the seedling substrate is high, the success rate of seedlings is low, and it is easy to damage the seedlings; The gantry type seedling picking device in patent CN102960107A is a mechanical seedling picking device with the same principle as the present invention, but it requires a large driving torque, cannot be loaded on the actual transplanting machine, and cannot meet the requirements applicable to various plug trays. Single application, not programmable
