Problems solved by technology

The machine is composed of three parts: the transplanter body, the control unit (PLC) and the pneumatic power source. The transplanting manipulator has multiple functions such as clamping seedlings, placing seedlings, planting and soil suppression. The disadvantages are: poor operation stability, Affect the quality of transplanting, the degree of automation is low, need to manually feed the seedling tray, and the transplanting efficiency is not high
Using trajectory planning to determine the kinematic characteristics of the end effector of the transplanting manipulator, and using ADAMS software to simulate and analyze the rationality of the mechanism design, but the research stays at the conceptual design
In 2012, Mao Hanping and others of Jiangsu University proposed a two-finger and four-needle clamp-type seedling picking method (application number: 201210476721.0), and developed a corresponding seedling picking end effector (application number: 201210477010.5). It is flexible and reliable, and has outstanding innovations in seedling clamping, picking, and putting seedlings, but there is no device to automatically complete the work of picking seedlings
[0005] In short, the automatic transplanting technology of plug seedlings in my country is still in the exploratory stage and has not been put into production practice. It is necessary to further study the automatic seedling picking device of the plug seedling transplanting machine with relatively simple structure and reliable performance to replace human manual labor. Automatically complete the removal of seedlings from the plug tray and planting operations

Abstract

The invention provides an automatic seedling taking manipulator for a plug seedling transplanter. The automatic seedling taking manipulator comprises a seedling taking manipulator and a seedling taking end effector (7), the integral structure is a Cartesian motion system, the seedling taking end effector (7) is driven by a motor (4-7) to shift back and forth along an X-axis in an X-Y plane to align with a hole to be prepared to take a seedling and align with a flowerpot to be prepared to plant the seedling, different air suction and air exhaust modes of the upper end and the lower end of a rodless cylinder (5) drive the seedling taking end effector (7) to slide up and down along a Y-axis in the X-Y plane to take the seedling from a hole dish (1) and plant the seedling in the flowerpot (8). The automatic seedling taking manipulator can replace hand labor of a man, the seedling is taken out from a hole of a source dish and transplanted in a target growing dish or the flowerpot, the integral structure is simple, the performance is reliable, and the automatic seedling taking manipulator is applicable to automatically transplanting the plug seedlings of different specifications.

Description

technical field [0001] The invention belongs to the technical field of facility agriculture, and in particular relates to a greenhouse seedling transplanting machine, in particular to a seedling picking device that can automatically take out seedlings from holes in source trays and transfer them to target growth trays or flower pots for planting. Background technique [0002] Seedling transplanting of vegetables, flowers and other crops has long been a beneficial and specialized greenhouse production mode (Ting et al., 1992). After the plug seedling technology appeared in the 1970s, it showed strong vitality. Since entering the 21st century, this technology has been widely used in the production of annual and biennial herbaceous flowers and perennial flowers, and has also been widely used in many vegetable crops and some economic crops such as tobacco and rapeseed. my country has preliminarily established an industrialized seedling raising technology system, and the annual ...
