The conventional one is configured as described above, and when the seedling placing table (10) in each of the transplanting units (7a) and (7b) is laterally fed forward and backward, the seedlings are taken out from the seedling tray (11) forward and backward directions. The nail (12) and the seedling push-out pin (87) are synchronously operated to take out the seedlings, and the taken-out seedlings are transferred to the nails (13) for planting seedlings.

According to the conventional type as described above, since the transplant unit is pulled by the tractor, the unplanted portion can be formed on the headland due to the length of the tractor, and the contour line work can be performed on sloped land. Since the transplant unit does not run in the same way as the tractor, there is a drawback that the planting position shifts. In this proposal, the traveling unit is directly attached to the transplant unit in order to improve the above drawbacks. In FIGS. 1 and 2, (100) is a transplantation frame, and front and rear wheels (101) and (102) are located below the transplantation frame so that it can be driven by an engine (103) mounted in the front. Further, there is a seat (104) behind the frame (100), and the transplant unit (A) is installed between the uniform seat (104) and the engine (103). The main frame (105) on the transplanting frame (100) has a mounting table (106) on which seedling trays are loaded, and a pot for one strain taken out from this seedling tray by the seedling take-out nails (107). It is equipped with a hopper-shaped seedling claw (108) for planting seedlings and a soil soil roller (109) for covering the seedlings after planting, and the elevator mechanism (110) raises and lowers in a substantially elliptical locus. When the planting claw (108) rises, the seedlings supplied and dropped from the seedling take-out claw (107) are received, and when the planting claw (108) descends, the seedlings are planted in the transplant holes formed on the ridge surface. The seedling planting claw (108) is attached to the planting transmission case (112) via the planting arm (111), the lateral feeding mechanism (113) of the seedling placing table (106), and the seedling tray. The feeding mechanism is the same as the conventional one. Further, the operation column (114) is provided on the side of the main frame (105) facing the seat (104), and the traveling handle (115) is provided on the operation column (114). Further, a gauge wheel (116) is attached to the transplantation frame (100) behind the front wheel. A specific drive system for the front and rear wheels (101), (102) is shown in FIG. 3, in which the pulley (128) is driven from the engine (103) via the pulley (126) and the belt (127), A split pulley (130) is provided on the shaft (129) of (128), and from this, the split pulley (131) is driven via a belt. The split pulley (131) drives a gear mechanism in the mission case (132) via the main clutch (137), and the gear (133) is driven by this gear mechanism, and the gear (133) is the propeller shaft (134). The front wheels (101) and the rear wheels (102) are driven via the differential gear mechanism (135) (136) in the differential case. Further, the shaft (139) is driven from the shaft (129) via the bevel gear mechanism (138), and the continuously variable transmission belt mechanism (140) is driven. The input shaft (142) of the bevel case (141) is rotatably linked to the continuously variable transmission belt mechanism (140), and drives the shaft (143) of the bevel case (141) from the shaft (142). Driving the seedling picking claw driving system and the planting claw driving system directly from the shaft (143) without using the swinging chain case as in the conventional case is no different from the conventional one.

The transplanter as described above is driven by the engine (103) and is driven by the front and rear wheels (101) (102), and the operation is controlled by the operator sitting on the seat (104) and holding the handle (115). Since it is a steering device, the transplanting machine runs alone to perform planting, so the planting efficiency is wide, no unplanted part occurs on the headland, and the planting position does not shift laterally during contour line work on sloping land etc. . Although the wheels are shown as the traveling bodies in the above embodiments, crawlers may be used.

4 and 5 show a dedicated riding transplanter having two transplanting units on the left and right. A crawler (118) or wheels are attached to a transplantation frame (144) provided on a vehicle body frame (117), an engine (119) is mounted in front of the vehicle body frame (117), and a step (123) is provided behind the vehicle. , Which has a seat (120). Further, there is an operation lever (121) in front of the seat (120). A guide bar (122) is horizontally installed on the body frame (117) so that the transplant frames (144) of the left and right transplant units (124) (125) can be moved along the guide bar (122). Has become. Along with this movement, a normal mechanism is adopted in which transmission from the engine pulley is always performed. It goes without saying that a means for fixing at the moved position is also provided.

In the conventional transplanter, it is necessary to adjust the planting part and the traveling wheel when adjusting the striation. However, as shown in the figure, since the transplant units (124) and (125) can move along the guide bar (122), the inter-plant adjustment and the inter-wheel adjustment can be performed at the same time. At the same time, it is possible to prevent the body from slipping sideways. Therefore, the planting position does not shift laterally.

[0021]

[Effect of device]

 According to the proposed method, the traveling unit is directly mounted on the frame of the transplanting unit for transplanting, so that the planting efficiency is good and the unplanted part of the headland is small, and the planting position during contour line work on sloping ground etc. Has the effect of not laterally shifting.
