Groove type cam folding and unfolding device for multiple seedling-taking end effectors

Abstract

The invention relates to a groove type cam folding and unfolding device for multiple seedling-taking end effectors. The device consists of a folding and unfolding plate, a synchronous belt guide rail, a linear guide rail, a square slide block, a rotating shaft, a servo motor, a beam and a mounting rack, and is characterized in that the mounting rack of the multiple seedling-taking end effectors is pushed to be folded or unfolded through slippage of the folding and unfolding plate, so that the seedling-taking end effectors take and put the seedlings in a dispersing or gathering mode, and plug seedlings with different specifications and sizes are automatically transplanted. The groove type cam folding and unfolding device has the characteristics that a chute with a certain regular inclined angle is formed on the folding and unfolding plate, the seedling-taking end effectors are pushed to be unfolded or folded by utilizing the relative slippage of the chute, only one power driver is required, and the groove type cam folding and unfolding device for multiple seedling-taking end effectors is simple in structure and easy to control and can be applied to an automatic plug seedling transplanting system comprising the multiple seedling-taking end effectors.

Description

technical field [0001] The invention relates to an unfolding device aimed at the action of multiple seedling-taking end effectors in the automatic transfer of plug seedlings, in particular to a device that uses a grooved cam mechanism to unfold or close a plurality of seedling-taking end effectors. Background technique [0002] Since the 1980s, protected horticulture in my country has achieved unprecedented development. The planting area of ​​protected vegetables has reached 3.3 million hectares, ranking first in the world in terms of total area. Among them, the proportion of multi-span greenhouses representing the modernization level of protected horticulture has increased year by year. However, in addition to the greenhouse frame and small gardening management machines, facility agriculture seriously lacks mechanized equipment in the main production links, and the per capita management area of ​​facility horticulture is only equivalent to 1 / 4~1 / 5 of the Netherlands.

AI Technical Summary

Problems solved by technology

The simplest configuration of multiple seedling-taking end effectors is to install them in fixed positions against holes, which limits the size of the hole trays. Changing a different type of hole tray requires re-adjusting the installation position of the seedling-taking end effectors, which has poor adaptability to the hole trays.

Multiple seedling-taking end effectors can also be dispersed and moved to each other, so as to take seedlings and plant seedlings for different specifications and sizes, but each movement requires a power drive, such as the XT616 transplanter produced by TransplantSystems in Australia, Shenyang Agricultural "An automatic transfer machine for plug seedlings" of the University (application number: 200910187621.4), etc., when the number of movable seedling-taking end effectors is large, the power drive system is huge, which increases the burden on the mobile platform, and the movement control is complicated
