Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a transplant device having two or more transplant tools attached to the side of a rotating case.

(Prior Art) Conventionally, as disclosed in Japanese Patent Publication No. 17806/1983, a transplant device is attached to the outside of a rotating case and is attached to a shaft which is transmitted by a transmission mechanism inside the rotating case separately from the rotation of the rotating case. There is a transplant device in which a transplant nail that opens and closes is attached to the transplant tool. However, in this conventional transplant device, the transplant tool is small compared to the rotating case, and the transplant nail and the main body of the transplant tool are arranged with a considerable distance from each other in the front and rear.

That is, the entire length of the transplanting tool, in which the pair of transplanting claws pinch out the seedlings from the seedling tank side, transfer them to the lower soil surface, and release them, was provided within the station of the rotating case.

(Problems to be Solved by the Invention) In the conventional transplanting device, the transplant claws that operate to open and close cannot be made long unless the rotating case is made larger.At this time, if the rotating case is made larger, the seedling outlet side of the seedling tank becomes Raise it higher towards L,
It is necessary to make a large distance between the front and back of the center of the rotating case, which not only requires a larger transplanter but also increases the transmission load, making it impractical.

(Means for Solving the Problems) The present invention takes the following technical means to solve the problems of the prior art described above.

That is, the present invention provides a plurality of locations on the side of the rotating case (28) that are spaced a certain distance from the rotational axis (A) of the rotating case (28) as appropriate as the rotating case (26) rotates. A shaft (31a) is provided which is transmitted and rotated at the same rotation speed as that of the rotation case (28) while the rotation is shifted, and the case (32a) of the seedling transplanter (32) is attached to this shaft (31a).
At the same time, a cam mechanism is installed in the rotating case (26) that operates at least one of the pair of transplanted claws (33a) and (33b) attached to this case (32a) to widen or shorten the gap between the claws. ) and the shaft (31a), and the transplanted nails (33a) and (33b) to be attached to the case (32a) (1) other transplant cases whose distal ends are adjacent to each other; The structure of the implant device is such that it extends to the outer surface of the implant and intervenes.

(Operations and Effects of the Invention) The present invention provides the rotating case (26) with the above configuration.
When the is rotated by transmission, the transplant device (3
2) operates in a vertically long closed loop-shaped transplant locus, and along with this, the pair of transplant claws (33a) and (33b) are opened and closed by the action of the cam mechanism to transfer the seedlings to the seedling tank. Divide from the side and transplant to the soil surface.

At this time, in this invention, the distal ends of the pair of transplanted claws (33a) and (33b) that operate to open and close extend to the side of the adjacent transplantation tool (32) when drawing the transplant trajectory,

In addition, (42) in the figure shows the leveling float.

Next, the operation of the upper side will be explained.

The seedlings are stored in the seedling tank (7), and the towing vehicle body pulls the transplanter side with the soil leveling float (42) in contact with the topsoil surface of the paddy field, and power is applied to each operating part in the transplant transmission case (1). introduce.

Then, the seedling tank (7) is reciprocated from side to side, and the lower end of the seedling in the seedling tank (7) is received by the seedling receiving frame (20) and slides into contact with the seedling receiving frame (20). The seedlings from the lower part will be brought out one after another.

On the other hand, when the rotating case (26) is rotated by the drive shaft (5), the counter eccentric gear (3
0) and the eccentric planet gear (31) are the sun gear (28)
The planetary gear (31)
The transplant device (32) will be rotated by the shaft (31a) that is integrated with the shaft (31a). In addition, the cam body (37) is connected to the cam shaft (38
) and is integral with the rotating case (26), so there is a shift in the operation of the transplanter (32).

Therefore, a part of the cam floor of the interlocking member (38) comes into contact with the cam body (37) and rotates around it.
The shaft (34) to which the transplanted claw (33b) is attached and the spring (3)
5), the transplanted claw (33b) moves toward the fixed transplanted claw (33a) and remains in a stopped state, and then, when a part of the cam floor reaches the stepped part of the cam body (37). The transplanted nail (33b) is rapidly fixed with the spring (35) against the transplanted nail (33a).
) will open.

That is, both lower ends of the transplanted nails (33a) and (33b) are operated while drawing the transplantation trajectory (d), but the transplanted nails (33b)
) intervenes into the seedling tank (7) from above, it is in a stopped state where it is opened at a predetermined interval with respect to the fixed transplant claw (33a), and when dividing seedlings of a predetermined width, the claw is further opened from this state. It operates so that the distance between (33a) and (33b) becomes narrower to divide and hold the seedlings. Then, while maintaining this state, when the transplanted nail (3) is inserted into the topsoil surface, the spring (35)
3b) rapidly opens from the fixed transplanted claw (33a) and releases the seedling that it was holding. After that, the transplanted nail (33a)
, When (33b) starts to move upward, the gap between the transplanted claws becomes slightly narrowed, and when the seedlings are pushed into the tank (7), the cam body (
37), the seedlings will be pinched and separated.

In this way, the two seedling transplanting tools feed out the seedlings to the seedling dividing opening (25), and the seedlings are successively divided, carried to the soil surface, and transplanted.

In this way, the seedling transplanting work is carried out, and when separating the seedlings from the seedling tank (7), the transplanting claws (33a) and (33b) that open and close extend out from the rotating case (2G). Even when the seedlings are separated in the same state and transplanted to the soil surface, the seedlings can be separated by plunging deep into the soil surface and transplanted reliably.

During the inactive state until the seedling moves up after transplanting and plunges into the primary seedling tank (7), the other transplant A that is currently transplanting the seedling
Since the transplant claw that opens and closes the outer surface of (32) can pass through, the transplant function can be fully demonstrated without increasing the size of the two-turn case (28), and reliable transplantation can be performed.

As shown in FIG. 5, the case (32a) of the transplant device (32) can be attached to the shaft (31a) by attaching the metal (32b) for attachment to the outside of the case (32a). However, in this case, the shaft (31a) must not be made cylindrical, but the camshaft (38) side must be made cylindrical, which is the opposite of the previous example.
