Control system of suspension type automatic transplanter and control method thereof

Abstract

The invention discloses a control system of a suspension type automatic transplanter and a control method thereof, and relates to the technical field of agricultural machinery equipment automation, and the control system comprises a box moving control system, a seedling taking and dropping control system and a main control unit; the box moving control system comprises a plug tray transverse feeding driving motor, a plug tray in-place sensor and a plug tray longitudinal shifting cylinder; the seedling taking and throwing control system comprises a first limiting sensor arranged on a transverse moving cylinder, a second limiting sensor arranged on a seedling claw lifting cylinder, a third limiting sensor arranged on a longitudinal moving cylinder, a fourth limiting sensor arranged on a seedling claw opening and closing cylinder, a seedling separating cup in-place sensor and a seedling separating cup counter D0; according to the invention, the main control unit controls the box moving control system and the seedling taking and dropping control system to coordinate and cooperate, so that automatic seedling taking, seedling dropping and seedling separation can be realized, the seedling taking speed is increased, and full automation of the transplanting process is realized.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery equipment automation, and more particularly to a control system and a control method of a hanging automatic transplanter. Background technique [0002] my country is a big country in vegetable cultivation. The vegetable planting area in my country has reached 300 million mu, with an annual output of more than 700 million tons, and it is still growing. The cultivation of agricultural vegetables in my country mostly adopts the method of raising seedlings in plug trays and then transplanting them. This method has huge economic and social benefits. Therefore, it is very necessary to develop automatic transplanting machines suitable for my country's national conditions to realize large-scale vegetable cultivation. [0003] At present, the transplanting of vegetables in my country is still dominated by semi-automatic transplanting machines, which require manual removal of seedlings from t...

Problems solved by technology

In the prior art, the publication number is CN104737686A, which discloses a motion coordination control system and control method for automatic transplanting machine for plug seedlings. Through the combination of PLC and relay, the coordination of the movement of the transplanting machine is realized by using the relay to turn on and off the power. Control, the control system is relatively complicated, the space of the horizontal feeding mechanism is large, the transplanting efficiency is limited, and it is not suitable for high-speed transplanting

The publication number is CN106358537A, which discloses an automatic transplanter for plug seedlings and its control system. The seedling separation mechanism of the transplanter picks up seedlings in motion. When the speed is fast, hanging seedlings are likely to occur, and the seedling throwing posture is not good. and other problems, it can only take seedlings at one speed, and cannot adapt to the coordinated movement between feeding seedlings and separating seedlings at different speeds
