The seedling division openings 25, 25 ... Are punched. Reference numeral 26 denotes a rotating case, which is mounted at this angular shaft portion with the tip end side of the drive shaft 5 as an angular axis so as to rotate integrally with the drive shaft 5.

Reference numeral 27 denotes a metal, which is fastened to the vertical case 4 with a bolt, supports the drive shaft 5 via a bearing, and has a metal tip end side extending into the rotary case 26. 28 is a sun gear, which is the rotating case 26
It is housed inside and is fixed to the metal 27 with the key 29 so as not to rotate, and the axis of the drive shaft 5 and the center of the sun gear 28 are arranged so that the pitch circle is eccentric with respect to the drive shaft 5. It is provided in a state where it is misaligned.

A counter eccentric gear 30 meshes with the sun gear 28. Reference numeral 31 denotes an eccentric planetary gear integrally provided with a cylindrical outer shaft 31a,
It meshes with the counter eccentric gear 30, and one end of the outer shaft 31 a projects to the outside of the rotating case 26. Reference numeral 32 denotes a transplant case, which is composed of a case body 32a, a mounting body 32b and a cap 32c, and an inverted U-shaped seedling transplanting claw 33 is attached to the front end portion of the case body 32a.

Reference numeral 34 designates a seedling pushing tool which operates so as to rapidly separate the seedlings held by the seedling transplanting claws 33 at the time of transplanting the seedlings. The side is inside the case main body 32a, and is attached to the interlocking member 36 which is supported inside the case main body 32a by a pin 35 and rotates. A cam floor 36a that contacts a cam body described later is integrally provided at the base end of the interlocking member 36.

Reference numeral 37 denotes a cam body, the outer peripheral surface of which is formed into a spiral portion, a perfect circle portion, and a step portion.
8 is integrally provided, and the tip of the inner shaft 38 is attached to the angular shaft 38a.
Is formed. Then, in order to assemble the cam body 37 to the case body 32a, the bearing 39 is attached to the mounting body 32b, the inner shaft 38 is inserted into the hole of the bearing 39 from the outside, and the root of the cam body is attached to the bearing. After being received by 39, the mounting body 32b may be fixed to the case main body 32a with bolts 40, 40 as mounting tools.

Then, with the case body 32a, the mounting body 32b and the cam body 37 assembled in this manner, the inner shaft 38
Is inserted into the hole of the outer shaft 31a from the outside. At this time,
On the inner wall surface of the rotating case 26, the tip end side angular shaft 38a of the inner shaft 38 is formed.
The inner shaft 38 is provided with a square hole 41 as an engaging portion into which the
Is configured not to rotate. Further, a mounting body 32b is inserted through the outer peripheral surface of the outer shaft 31a, and the outer shaft 31a and the mounting body 32b are mounted by a cotter pin 42 so as to prevent them from coming off and rotating.

Reference numeral 43 denotes a spring, which is provided inside the cap 32c covering the upper part of the case body 32a so as to lower the rod 34a of the seedling pushing tool 34. Reference numeral 44 indicates a leveling float. Next, the operation of the above example will be described. The seedling is stored in the seedling tank 7 and the transplanter side is leveled with the towing vehicle.
Pulls the paddy in contact with the surface soil surface of the paddy field and transmits power to each operating part in the transplantation transmission case 1.

Then, the seedling tank 7 is reciprocated right and left,
The lower end side of the seedling in the seedling tank 7 is received by the seedling receiving frame 24 and slides. Then, the seedlings on the lower side portion are successively fed to the seedling dividing port 25. On the other hand, when the rotating case 26 is rotated by the drive shaft 5, the counter eccentric gear 30 and the eccentric planetary gear 31 in the rotating case are rotated by the sun gear 2.
The planetary gear 31 is rotated while rotating around 8
The transplantation case 32 is rotated by the outer shaft 31a integrated with the transplantation case 32. Further, since the cam body 37 is integrated with the rotating case 26 via the inner shaft 38, the transplant case 32
There is a gap in the operation of. Therefore, the interlocking member 36
The cam floor 36a of the above comes into contact with the cam body 37 and rotates around this, and the seedling pushing tool 34 is pulled up against the spring 43 and stopped, and then the cam floor 36a.
Is rapidly lowered by the spring 43 when it reaches the stepped portion of the cam body.

That is, the lower end of the seedling transplanting nail 33 is actuated by drawing a transplanting locus C, but when the seedling transplanting nail 33 intervenes in the seedling tank 7 from above, the seedling extruding tool 34 stops above and seedling transplanting is performed. This state is maintained until the nail 33 plunges into the surface soil surface of the paddy field, and when the nail 33 plunges into the surface soil surface, the seedling pushing tool 3 is pressed by the spring 43.
4 rapidly moves down, releasing the seedlings it was holding.
After that, when the seedling transplanting nail 33 starts to move upward, the seedling pushing tool 34 is pulled up again by the cam body 37 and the interlocking member, and the seedling tank 7
When it plunges into, it will be in a stopped state.

In this way, the seedlings fed to the seedling dividing port 25 by the two seedling transplanting tools are sequentially divided and carried to the soil surface for transplantation. Therefore, in this implanting device, when the implant case 32 is substantially attached to the rotating case 26, the outer shaft 31a is firmly supported by the rotating case 26 in a freely rotatable state, and the inner shaft is attached to the central portion of the outer shaft 31a. 38 is inserted and the square hole 41 on the inner wall surface of the rotating case 26 is inserted.
Since it is configured to hold the transplant case 32 in a predetermined posture by the gear transmission mechanism, it is compact as a whole, and the transplant case 32 is properly operated without rattling. Will be transplanted in a proper posture without being disturbed.

Further, the case body 32 of the transplant case 32
A mounting body 32b is attached to a bolt 40 as a mounting tool.
Since it is configured to be clamped and fixed in the left-right direction of the machine, the width of the transplanting device in the left-right direction of the machine can be made small, and a small and lightweight seedling planting machine can be obtained. Furthermore,
By attaching and detaching the cotter pin 42 between the outer shaft 31a and the attachment body 32b, the implant case 32 is attached to the rotary case 26.
It is extremely easy to attach and remove.
