However, in all of the above-described soil covering devices of the transplanter, the soil covering device is mounted above the tip of the hopper portion of the borer, and the soil covering device is moved from the seedling supply device to the borer. Even if soil is covered with a conventional device after transplanting the seedlings supplied to the hopper portion of the hopper portion, the soil cannot be sufficiently covered, and the transplanted seedlings may fall down. However, it was often necessary to perform the soil covering work manually after the transplantation work was completed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 to 3, reference numeral 1 denotes a body frame of a traveling body 4 having left and right front wheels 2, 2 and rear wheels 3, 3, and 5 denotes an engine mounted on a rear portion of the body frame 1. Power from the transmission 5 is transmitted to the rear wheels 3 and 3 via the transmission case 6. 7, 7 is the body frame 1
Left and right seedling supply seats 8 are disposed at the upper left and right ends of the vehicle and face the transplanting device described later. Reference numeral 8 denotes a steering handle for steering the front wheels 2, 2 provided between the left and right sides of the seats 7, 7. is there. A driving operation unit 9 is provided on the rear side of the seats 7, 7, and a seedling supply unit 11 facing above the planting unit 10 is provided on the front side of the seats 7, 7. Driving operation section 9
, Side clutch levers 12a, 12a, a main clutch lever 12, a forward / reverse switching lever 13, a transplant working device clutch lever 14, and a switching lever 15 for switching a transplant working speed and a traveling movement speed are arranged in parallel.

As shown in FIGS. 5 to 10, the seedling supply section 11 is a rotary pot 1 in which a plurality of cylindrical seedling pots 16 for supplying seedlings P are mounted on a disk-shaped rotating body 17 at equal intervals.
8 and four sets of the rotary pots 18 are provided on the working machine frame 19 in parallel. Reference numeral 25 denotes a bottom plate of the seedling pot 16. The bottom plate 25 is configured such that when the rotary pot 18 rotates, the seedling pot 16 is opened.
When it faces above 0, it comes off the guide and opens downward, allowing the seedlings P to fall naturally. 25a is the bottom plate 2
5 is a stopper for restricting the swing of 5.

The planting section 10 comprises a tubular main body 26 for receiving the seedlings P from the seedling supply section 11 and beak-shaped divided hoppers 27a and 27b for opening and closing the lower end side. Four sets are provided side by side, and the left and right crank portions 28,
At 28, the planting unit 10 is rotated by two sets of right and left along a rotation locus A indicated by a two-dot chain line to receive the seedling P at the upper movement position, and then the split hoppers 27a and 27b are moved to the field a at the lower movement position. A hole is made, and then the split hoppers 27a and 27b are opened as it rises from the lowering position.
Drop and plant. One split hopper 27a has a long
A support 29a having a hole 29 is mounted by a pin 29b so that the angle can be adjusted, and a cover plate 29c is attached to an end of the support 29a.

That is, a planter drive shaft 32 is interlocked to a transmission shaft 31 protruding from the transmission case 30 by a chain 31 a, and an operating arm 34 is connected to a crank arm 33 provided on the planter drive shaft 32. The operating arm 34 has an intermediate portion pivotally supported by a rotating arm 35, and a distal end of the operating arm 34 is pivotally supported by an upper link arm 37 of a link 36 supporting the planting portion 10. The upper link arm 37 and the lower link arm 3 of the link portion 36
8 is supported at its base end by a support plate 39, and the support plate 39 is swingably supported by an arm 40 constituting a link portion 36. Therefore, the link portion 36 swings up and down and back and forth by the rotation of the planter drive shaft 32 without changing the posture of the link portion 36.
This is an operating rod that opens and closes the 0 divided hoppers 27a and 27b at the lower movement position. Reference numeral 42 denotes a brush attached to the inside of the planting section 10, which is used for transplanting.
By holding the seedlings P supplied to the planting portion 10 from the brush 42 with the brush 42, the planting operation can always be performed at the center position of the planting portion 10 regardless of the size of the seedlings P.

In the above configuration, when transplanting the seedlings P of the satsuki seedlings, the front wheel 2 and the rear wheel 3 of the traveling machine 4 are positioned via the lifting drive cylinder and the rolling cylinder with the front wheel 2 and the rear wheel 3 positioned in the groove b of the field a. To set the transplantation working device to a predetermined implantation depth. Then, while the traveling machine 4 is traveling along the groove b of the field a, the operators sitting on the left and right seats 7 take the seedlings P from the seedling mounting table and supply the seedlings P to the seedling pots 16. Pot 18
As described above, the planting unit 10 intermittently rotates in conjunction with the vertical movement of the planting unit 10, and the planting unit 10 that rotates up and down sequentially receives the seedlings P from the seedling pot 16 and the split hoppers 27 a and 27 b move in the front-rear direction.
