Wherein, power input shaft is also referred to as partial gear axle, is connected with partial gear using flat key, and two ends are separately installed with two
Bearing block, the located lateral of deep groove ball bearing uses sleeve and bearing block, and bearing block, which is bolted, is fixed on transplanter
In frame.
According to the top seedling device of the present invention, during hole tray transplantation of seedlings, push rod is first passed through by seedling matrix and the broken knot ejection of hole tray
Hole tray, then seedling stalk is gripped with pointer clamping type seedling taking mode, reach the effect that low damage is transplanted, described its end of push rod
Accumulate larger with seedling substrate interface, seedling medium will not be caused damage.With conventional directly with seedling pin insertion seedling medium
Middle gripping seedling compares, the problems such as this method largely avoids damage to seedling stalk, root system and matrix structure, contracting
Short recovery cycle of the seedling in field, while also improving the efficiency of transplanting.
In addition to objects, features and advantages described above, the present invention also has other objects, features and advantages.
Below with reference to figure, the present invention is further detailed explanation.

Embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
As shown in Figure 1, 2, a kind of Plug seedling top seedling device based on partial gear rackwork, including partial gear
Rack assembly, bearing spider component, push rod 5 and back-moving spring 4.Partial gear rack assembly includes：It is partial gear 9, straight
Gear rack 3, rack guide rail 1 and partial gear axle 7.Wherein, partial gear 9 is not involute spur gear, and not
Complete gear shaft 7 is connected using general flat key 13, and spur rack guide rail 1 is fixed in transplanter frame.Described incomplete tooth
Wheel assembly is fixed on bearing block 8, and partial gear 9 is attached with power input shaft by flat key 13.Described its end of push rod 5
Portion's diameter is adapted with hole tray bottom part aperture diameter, and the one end of back-moving spring 4 is contacted with spur rack 3 during the seedling of top, and the other end is in straight-tooth tooth
