Method and system for taking seedlings in rows at intervals and placing seedlings in sequence by means of pot seedling transplanter

Abstract

The invention provides a method and system for taking seedlings in rows at intervals and placing the seedlings in sequence by means of a pot seedling transplanter. The system comprises a tray conveying device, a swinging type seedling taking device, a rotational seedling separating device and a control unit; the tray conveying device is installed behind the rotational seedling separating device and can achieve left-right translation actions of trays, the translation distance can be adjusted, vertical feed motion is achieved, a row is fed every time, and feeding is controlled by a first photoelectric sensor; the swinging type seedling taking device is located over the rotational seedling separating device, and a seedling taking claw set can take half row of the seedlings at a time; the rotational seedling separating device cooperates with the swinging type seedling taking device, and the seedlings on the swinging type seedling taking device are put into the rotational seedling separating device through a second photoelectric sensor and program control. The method can be suitable for different trays, different planting speeds and unstable planting speeds, tray feeding and seedling taking without interruption can be achieved, and the in-row seedling taking efficiency is high; the overall structure is simple, and the system can be carried on a mobile transplanter.

Description

technical field [0001] The invention belongs to the field of automatic transplanting research in facility agriculture, and in particular relates to a method and a system for taking seedlings at intervals in rows and placing seedlings sequentially by pot seedling transplanting machines. 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 actio...

AI Technical Summary

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.
