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 Transplant Systems in Australia, Shenyang "An automatic transfer machine for plug seedlings" of the Agricultural 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 complex

Embodiment Construction
[0014] The unfolding plate is a key part of the unfolding mechanism of the seedling-taking end effector, which completes the unfolding or closing action of the seedling-taking end effector. The plywood is a flat plate with chutes at different inclination angles. For the plywood that unfolds or closes the end effector for seedling taking at equal intervals, such as a plywood with 6 chutees at equal intervals, its structure is shown in Figure 3. After the center line of each chute is extended, it converges at a point O, and OB, OC, OD and OB′, OC′, OD′ are left and right symmetrical along the OA line, that is, ∠BOA=∠B’OA, ∠COA=∠C′OA, ∠DOA=∠D′OA. When the seedling-taking end effectors are unfolded or closed at equal intervals, the angular relationship satisfies: tan∠BOA:tan∠COA:tan∠DOA=1:3:5, that is, the tangent value of the angle between the center line of each chute and the symmetry line Odd ratio. Driven by a motor, the cam expansion plate containing 6 chutes slides to push...

The invention relates to a groove type cam unfolding and folding method of a plurality of seedling taking tail end actuators. Sliding chutes adopted in the method are distributed on a cam unfolding and folding plate according to a certain rule, i.e. the sliding chutes are symmetrically distributed in the synchronous belt guide rail direction, the center lines of each sliding chute extend and are then gathered into one point O, the symmetrical axis of the sliding chute distribution is OA, the tangent value ratio of included angles between the center lines of each outward sliding chute from the symmetrical axis OA and the symmetrical axis OA is 1:3:5:7 to (2n-1), and n is one half of the number of the sliding chutes. Through the driving of one motor, the cam unfolding and folding plates of a plurality of sliding chutes glide for pushing the seedling taking tail end actuators to realize the unfolding and folding action for adapting to seedling taking steps and seedling placing steps of plug seedlings at different gaps. The method has the advantages that only one motive power is needed for driving, the structure is simple, the control is easy, and the method can be applied to a plug seedling automatic transplantation system containing a plurality of seedling taking tail end actuators.
Description
technical field [0001] The invention relates to a method for unfolding and closing multiple seedling-taking end effectors in the automatic transfer of plug-in seedlings, in particular to a method for unfolding or closing the multiple seedling-taking end effectors by using a grooved cam mechanism. 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.
