A pair of left and right mounting plates 12A and a screw tightening means 7 (fulcrum) that joins the pair of left and right mounting plates 13A integrated with the pot seedling guide portion frame 13 constituting the rear machine body 20B. This screw tightening means 7 acts as a pivot point of rotation at the connecting portion d.
[0014]
Next, the movable state of the bending angle varying means e of the connecting portion d in FIG. 1 is illustrated. As shown in FIGS. 1 and 6, the angle varying means e is provided with a pin 21 on the lever 2 attached to the handle frame 15, the wire cable 3 extending from the lever 2, the potted seedling placement frame 12 and the mounting plate 12A. A lock fixing release metal fitting 5 that is pivotally attached using, a notch 22 provided around the attachment plate 13A at the tip of the potted seedling guide portion frame 13, a pin 23 provided through the lock fixation release metal fitting 5, and The urging means (tensile spring) 24 is provided between the spring receiver 12B projectingly contacted with the side surface of the mounting plate 12A and the spring receiver 5B projectingly contacted with the side face of the lock fixing release metal fitting 5. Note that a biasing force in the direction of the center (fulcrum 7) of the connecting portion d is always applied to the pin 23 that is in contact with the lock fixing release fitting by a tension spring 24. Thereby, when the notch 22 provided around the mounting plate 13A reaches directly above the pin 23, the pin 23 is fitted into the notch 22, and the front side 20A and the rear side 20B of the fuselage are fixed (locked). .
[0015]
By holding the lever 2 with a hand, a tension acts in the direction of arrow P via the wire cable 3 as shown in FIG. 7, the lock fixing release metal fitting 5 rotates around the fulcrum 21, and the pin 23 is cut. It is cut off from the notch 22 and is in a fixed release (unlocked) state. When the handle 14 is pulled up in this state, the machine body front side 20A rotates upward (in the direction of arrow R in FIG. 8) about the fulcrum 7 of the joint portion d.
[0016]
The angle varying means e is locked (fixed) at the time of steady transplantation. That is, the pin 23 is inserted into the notch 22, and the potted seedling placement part a, the potted seedling guide part b, and the feeding part c are locked. At least two notches 22 are provided at the circumferential end, and are locked at arbitrary bending angles by inserting the pins 23. The angle is provided so that it can be changed to at least two stages.

Further, as shown in FIG. 9, by providing a play in the notch 22, the pin 23 slides on the inner surface of the notch 22, and the front and rear of the fuselage can swing around the fulcrum 7 of the connecting portion. Since the planting part works as a buffer for the unevenness of the field ground in the range, the potted seedling feeding part c is devised to maintain a certain angle with respect to the field ground. That is, (a) in FIG. 9 shows the positions of the notches 22 and the pins 23 in the steady transplantation state, and (b) in FIG. 9 shows a stone or a lump of soil in the field, where the wheels 4 and potted seedlings are placed. The position of the pin 23 when the part a is lifted upward is shown. Furthermore, (c) of FIG. 9 shows the position of the pin 23 in a state where the wheel 4 is depressed in the depression on the concave surface of the farm ground. Even if the wheel 4 on the front side of the machine moves up and down by the angle r degrees shown in FIGS.
[0019]
The transplanting operation by the transplanter of the present invention is performed as shown in FIG. When the transplanter body 1 is pulled in the F direction, the continuous potted seedlings 34 are drawn out from the set continuous potted seedlings 33 placed on the potted seedling placement part a, and then pass through the potted seedling guide part b to pass the potted seedlings. The continuous potted seedlings 34 are transplanted into the planting grooves formed in the field from the feeding part c. In transplanting the potted seedlings, the angle between the potted seedling feeding portion c and the field ground 30 is appropriately about 20 to 30 degrees. Therefore, if this angle is maintained, the potted seedlings are properly planted.
[0020]
Next, the transplanting operation state at the field end 31 is shown in FIGS. When the lever 2 is operated when approaching the farm field end 31 such as a greenhouse, the planting side 20A is planted while lifting the front side 20A of the machine body upward by the traction handle 14, and the potted seedling placement part a is roughly at the farm field end 31 with respect to the field ground. Finish planting in a vertical position. By doing in this way, an untransplanted part can be decreased.
[0021]
The transplanter of the present invention is shown in FIGS. 1 and 3 , and the conventional transplanter is shown in FIGS. 2 and 4. When these are compared, the transplanter of the present invention has a reduced length of the potted seedling guide part a, resulting in In addition, the length of the main body 1 (total machine length) is greatly shortened. 2 and 4, the same parts as those of the transplanter of the present invention are indicated by the same reference numerals with dashes.
[0022]
Further, there is provided a transplanting machine in which the handle can be rotated rearward in the traveling direction for the purpose of expanding the potted seedling transplanting portion at the field end without using the angle changing means e. Schematic diagrams in this case are shown in FIGS. The handle 14 and the wheel 4 are separately attached to a pair of left and right receiving frames 26 attached to the potted seedling placement unit frame 12 as shown. The handle 14 includes a pin (fulcrum) 28 penetrating below the handle 14, an arc-shaped elongated hole 27 centering on the pin 28, a knob bolt 29 </ b> A for locking the elongated hole 27 and the handle 14, and a knob nut 29 </ b> B. The handle 14 is attached so as to be rotatable within the range of the long hole 27 with the pin 28 as a fulcrum. That is, the handle 14 can be fixed at an arbitrary position within the range of the angle S shown by tightening the knob nut 29B into the knob bolt 29A penetrating the elongated hole 27. As shown in FIG. 14, during normal potted planting work, the handle 14 is tilted forward most with respect to the traveling direction of the machine body, but the handle 14 is tilted farthest rearward at the field edge or the like. By planting the potted seedlings in the state (the handle is substantially perpendicular to the field), it becomes possible to plant more continuous potted seedlings by the length of L shown in the figure, and the number of untransplanted parts can be reduced.
