Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transplanter for planting seedlings such as vegetables taken out of a seedling mounting table into a field by planting claws. Conventionally, ridges have been formed by tilling work and ridge work, and seedlings such as vegetables have been planted on the upper surfaces of the ridges. However, since the width (groove shape) of the grooves formed between the ridges is formed unevenly, the running wheels are likely to meander due to a change in running resistance. Since the operator steering handle operation is performed by eye measurement, the distance between the ridge side surface and the planting position of the planting nail changes, and the direction in which the existing row of seedlings on the upper surface of the ridge intersects with the extension direction of the ridge (for forward movement) (Left and right direction), the spacing between the ridge side and the already planted seedlings, or the spacing between adjacent planting streaks when planting one ridge in multiple streaks, makes post-treatment work such as middle tilling and fertilization troublesome. There were problems such as damage to the seedlings during the operation and root rot of the seedlings caused by fertilization. [0004] However, the present invention provides a seedling mounting table, a planting claw, and a running wheel, respectively, and continuously runs the seedlings by the planting claw while running across the ridge. In the transplanter to be implanted in the axle frame, the engine is mounted on the machine base, the transmission case is fixed to the machine base, and the rear running wheels are provided on the transmission case via the telescopic axle case and the swingable axle frame. the only attached to the vehicle body frame, a slide cylinder provided on the machine base, the piston ends of the cylinders

The ridges (8) for planting are formed, and the front and rear running wheels (1) and (2) are moved into the grooves (43) formed between the adjacent ridges (8) and (8). When the ridge (8) is formed by the shaping plate (42) when the ridge (8) is formed by the shaping plate (42), the ridge (8) ( When the interval of 8) changes, the width (A) of the groove (43) between the ridges (8) and (8) is formed unevenly, and the groove width (A) is smaller than the running wheel (2). When the furrow (8) collapses and the work cannot be performed, and the groove width (A) becomes considerably large, the running wheel (2) meanders due to a change in running resistance. However, the ridge work becomes extremely troublesome to make the running wheel (2) width and the groove width (A) substantially equal, so that the groove width (A) is formed larger than the running wheel (2) width. The width (B) of the ridge (8) is prevented from being reduced by the running wheel (2) when planting seedlings. A fulcrum shaft (4) is provided in front of the machine base (22).
