Protrusion part push locating rack 210 in X direction to the mobile preset distance of seed plate fixed mechanism 12, locating rack 210, which drives, to float
Locating piece 330, thimble 320 on frame 310 and floating shelf 310 move in X direction, at this point, 330 elasticity of locating piece is pushed against seedling
On the back side of the positioning plate 121 of disk fixed mechanism 12 (seed plate fixed mechanism is not shown in diagram).
As shown in figure 5 a and 5b, sending the conveyer belt of disk device 13 to start, stepping is primary, and drive seed plate fixed mechanism 12 is along X
Step motion (is not shown, ask structure chart 1 and Fig. 2) to seed plate fixed mechanism 12 in direction.During stepping, locating piece 330 is passed through
Corresponding location hole 122, and locating piece 330 is driven to the seed plate fixed mechanism 12 of Y-direction stepping by location hole 122 and is moved
Dynamic a distance, connects the floating shelf 310 of locating piece 330 and thimble 320 on floating shelf 310 in company with moving down, floating shelf 310
340 forced compression of floating shelf reset spring between locating rack 210.At this point, the center of thimble 320 on seed plate 20 to corresponding
The corresponding completion positioning in the center of one row's seedling cave leakage hole.
Floating seedling taking device 100 of the invention does two dimensional motion in X-direction and Y-direction and carries out seedling taking, and guarantee is fixed
Seed plate can be precisely overlapped at the seedling cave leakage hole center of seedling taking position with thimble center.
As shown in figures 6 a and 6b, the rotation of drive shaft 430 drives thimble cam 420 to rotate, the protrusion of thimble cam 420
Divide and pushes thimble push plate 360 mobile to seed plate fixed mechanism 12 (being not shown, ask structure chart 1 and Fig. 2) in X direction, thimble push plate
360 push thimble 320 mobile again, and thimble 320 passes through row's seedling cave leakage hole and ejects pot seedling.
Later, the protrusion part of thimble cam 420 leaves thimble push plate 360, and thimble 320 is in thimble reset spring 350
The lower position restored to before ejecting of effect；The protrusion part of positioning cam 410 leaves locating rack 210, and locating rack 210 is in locating rack
Restore under the action of reset spring 220 to initial position；Locating rack 210 drives locating piece 330 to be detached from location hole 122, floating shelf
310 and locating piece 330, thimble 320 are restored by floating shelf reset spring 340 to initial position thereon.Floating seedling taking device
100, disk device 13 and seed plate fixed mechanism 12 is sent to carry out stepping next time and positioning seedling taking work.
To sum up, as shown in fig. 7, floating seedling taking method of the invention includes the following steps:
S100, driving mechanism drive positioning mechanism Forward, and locating piece elasticity pushes against seed plate fixed mechanism；
S200 send disk device to drive the stepping of seed plate fixed mechanism mobile primary, and locating piece is positioned by seed plate fixed mechanism,
