Thus, as shown in FIG. 15, in the transplanting operation, two strips are planted at the same time in the first stroke, and after the planting operation is completed, the aircraft is turned to perform two strips at the same time in the second stroke. 4 plants are planted on 1 ridge surface (M), and further, the aircraft (1) is slid and planted between each left and right 2 lanes on the existing ridge surface (M). It is also possible to plant multiple strips such as 6 or 8 strips. In addition, the distance between the center of the left rear wheel (8) and the rightmost seedling (N) is adjusted by adjusting the right side within the range of the maximum slide amount (L0) of the airframe (1) during the planting operation in one stroke. Can be adjusted in the range of L1 to L2 (L2 = L1 + L0). Furthermore, by simultaneously planting two strips, the lateral feed amount of the seedling mounting table (21) can be reduced to reduce the entire width of the seedling feeding device (16), and the spacing between the planted seedlings (N) (L3 ) Can always be kept constant, and the handle (26) can be operated more easily than the operator position between the left rear wheel (8) and the rear value by setting the fuselage (1) to the leftmost position even in the wide lance. This makes it possible to improve the operability of the handle (26).
[0016]
Furthermore, by setting the center of the planting device (18) such as the planting claw (23) and the pressure reducing rollers (20a) (20b) to the approximate center of the machine body (1), the planting claw (23 ) And the pitching external force from the pressure-reducing rollers (20a) and (20b) can be received substantially evenly to improve the stability of the airframe. .

【The invention's effect】
As is apparent from the above embodiments, the present invention has the following effects.
Seedling planting in which the seedling (N) taken out from the seedling tray (22) of the seedling mount (21) by the seedling picking claw (23) is inherited and planted to the seedling planting claw (25) as in claim 1. In the transplanter equipped with a mechanism (18), two sets of seedling planting mechanisms (18) for planting two seedlings from one seedling tray (22) are arranged in the body, and the two sets of seedling planting A mechanism (18) is disposed between the left and right traveling wheels (8, 8), and two sets of seedling planting mechanisms (18) are provided between the left and right traveling wheels (8, 8). Since the horizontal mounting position can be adjusted to correspond to the tray, and the distance (K) between the centers of two adjacent seedling extraction claws (23, 23) can be adjusted , 288 holes or 200 It is possible to adjust the lateral mounting position of the seedling picking claw (23) corresponding to the type of the tray (22a) (22b) such as a hole. Than it is.
[0018]
As described in claim 2, two bottom projections (78a) at both ends are fitted and mounted on the upper end of the pot hole (22c) at the substantially central portion of the seedling tray (22) having a plurality of different types of holes. Since the nail set gauge (78) is provided, the lateral mounting position of the seedling extraction claw (23) corresponding to the type of the tray (22a) (22b) such as 288 holes or 200 holes can be determined. By adjusting, the distance (K) between the centers of two adjacent claws (23) and (23) can be adjusted accurately. Thereby, improvement of seedling collection accuracy can be achieved.
[0019]
As in claim 3, the width dimension (W) of the seedling picking claw (23) is formed on the surface of the claw set gauge (78) corresponding to the lower surface protrusion (78a) of the claw set gauge (78). Since the display part (78b) for display is formed, the adjustment of the crank arm (35) is integrated with the claw (23) in accordance with the width dimension (W) of the display part (78b) of the claw set gauge (78) during the adjustment operation. The mounting position can be adjusted to improve seedling collection accuracy.
