When actuating arm 29 further rotates because of minor axis 85a, swing arm 135 becomes the state that is pulled to back upper place, activation part 134 is because combining and rotate with guide finger 132c, limiting unit 134a and swing arm 135 butts, but allow cramp bar 132 to move up, hoe parts 131 shoal to being absorbed in gradually of ridge R.

And when to become the crankangle shown in Figure 17 be the state of 180 °, nozzle component 98 is extracted with hole W1 and starts to carry out closed action from seedling plantation, uproots parts 131 and also extracts upward from ridge R.

Described expanded hole W2 is than seedling the plantation large and shallow bowl-type of hole W1, overlapping with hole W1 with seedling plantation, in side, see that Shi Miao plants with the position of hole W1 as the darkest, in addition, when front is seen, seedling plantation, pours into water in expanded hole W2 and concentrates on the darkest seedling and plant and use hole W1 because the circular arc of the lower edge 131a of hoe parts 131 becomes the darkest with the position of hole W1, is effectively supplied in seedling N.

Because the top of the nozzle component 98 of seedling plantation utensil U1 is most advanced and sophisticated shapes, even if therefore hoe parts 131 are from starting to excavate the charging into originally in the R of ridge of expanded hole W2, resistance is also little, in addition, can not damage expanded hole W2.Owing to first forming expanded hole W2, therefore, than the situation without expanded hole W2, can the nozzle component 98 of seedling plantation utensil U1 afterwards be inserted in the R of ridge deeper with less resistance, form darker seedling plantation and use hole W1, and can seedling N be planted deeplyer.

Now explanation adopts the transplanting operation of described seeding transplant machine 1.

When moving seeding transplant machine 1 along ridge R, operator match with moving ahead of mobile body T ground and the trailing wheel 41A rear in left side follow away space G walking, the pot seedling N that is placed on the seedling-cultivating tray on preliminary seedling platform Y is supplemented to each seedling implementation K1.When an individual work, seedling N is rendered to each seedling implementation K1 continuously, when two individual works, everyone renders to the seedling implementation K1 every.

Utilization is from the power of the travel drive difference of gearbox M, plantation driving mechanism U2 transferring power from from plantation driving shaft 30 to seedling cultivation device U, the track L of the longer along the vertical direction substantially elliptical of seedling plantation utensil U1 is periodically moved up and down, be connected with moving up and down of seedling plantation utensil U1 and the hoe parts 131 of expanded hole digging mechanism 130 are moved up and down, and by the power transmitting to plantation driving mechanism U2, from planting driving shaft 30 differences, the supply driving mechanism K2 to seedling feedway K transmits, and turntable S is intermittently driven around the longitudinal axis 10.

Along with the rotation of turntable S, many seedling implementation K1 carry out intermittent movement on circular orbit.Gate 35 is closed by the 36b of closure midway of gate closing feature 36, on gate 35, supply with and have seedling N, at seedling plantation utensil, U1 arrives before seedling feedway P, when the rear end of seedling plantation utensil U1 by gate closing feature 36 arrives seedling and supplies with position P, gate 35 is all opened seedling N is fallen because force application part 37 is instantaneous, to come seedling feedway P under the seedling plantation utensil U1 of top dead centre supply with.

The seedling plantation utensil U1 of seedling cultivation device U accepts the supply of seedling N near top dead centre from seedling implementation K1, move down with together with the movement of mobile body T, to arriving lower dead center, insert ridge R and open, form seedling plantation hole W1 on one side, on one side by being accommodated in inner seedling N, to be released to ridge R upper, while then move up and close.This moves up and down and on-off action is periodically to carry out with the rotational synchronization of turntable S, at certain intervals seedling N is planted on the R of ridge.

In the situation that be planting depth adjustment to seedling plantation utensil U1 with respect to the penetration depth of the upper surface of ridge R, in left side, follow away the operator of space G that the adjusting lever of planting depth guiding mechanism 44 45 is swung forwards, backwards, change the setting height of grounding body 43.

Utilizing the nozzle component 98 of seedling plantation utensil U1 to form seedling plantation with before the W1 of hole, hoe parts 131 insert ridge R and deepen gradually, be formed on the plantation of formation seedling and with the precalculated position of hole W1, reach the expanded hole W2 of the bowl-type of depth capacity, when nozzle component 98 departs from seedling plantation with hole W1, hoe parts 131 also move up and arrive position of readiness.

In addition, the shape of each parts of described embodiment of the present utility model and all around separately, upper and lower position relationship forms as Fig. 1～23 is best.But, be not limited to aforementioned embodiments, also can carry out various distortion to parts, structure, or change combination.

For example, hoe parts 131 also can directly be fixed on the rear end of cramp bar 132, or form respectively left and right alar part 131L, 131R and they are separately fixed on fixing body 132C.

Also can on the fixing body 20 of turntable S, implant stud, make the circular hole 21A of turntable S and this stud chimeric, with nut, fix.

Before and after preliminary seedling platform Y also can make, the 123F of foot, 123R will give prominence to downwards from himself, using the 123F of front and back foot, 123R as support unit 123.

In addition, seeding transplant machine 1, also can plant at seedling the rear portion side of the plantation framework 82 of utensil U1 rear side, configuration height regulates the pair of right and left with ridge R butt freely to press pinch roller, rolled in its left and right sides in the plantation position of the seedling N of ridge R upper surface, with left and right, by pinch roller, to rendering to the seedling plantation being formed by seedling implementation K1, with the soil of the left and right sides of the seedling N in the W1 of hole, push and earthing.
