DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a 1'/F planting device of a transplanter in which a seedling planting tool is attached to a one-turn case.

Prior Art There is a one-night transplanting device for a transplanter as described in Japanese Patent Publication No. 49-31773.

Problems to be Solved by the Invention In the conventional device, in order to fix the support shaft of the tooth width to the side surface of the rotating case, a screw is formed on one end of the support shaft itself, the screw is made to protrude from the rotating case, and the screw is tightened with a nut 1-. It was configured.

However, this type of mounting structure for the spindle has the drawback that it is difficult to maintain the airtightness inside the rotating case, and the spindle may become loose due to loosening of the screws, causing it to rotate. Attaching the cam support shaft is done by the cam! I+
There was a problem in that the mechanism became unstable and accurate planting was not possible. In addition, if the conventional structure is used to attach the cam shaft to the rotary case, the thickness of the support part of the spindle on the rotary case side will be increased because the support I field will protrude from the rotary case side across the rotary case. There was a problem in that the weight of the five-turn case itself increased because it was necessary to prevent the support shaft from collapsing by making it larger.

Means for Solving the Problems In order to solve the above problems, the present invention has the following configuration.

That is, in this invention, the rotation case 22 is attached to the planting drive shaft 23 which protrudes outward from the planting transmission case 18 and is transmitted and rotated.
A sun gear 29 whose pitch circle is not V≦circle from the axis (c) of the drive shaft is installed in the rotating case 22 so as to rotate integrally with the lψ axis 23. The cylinder 1IIll131a is attached to the case 1128 side so as not to rotate, and is rotated integrally with the planetary gear 31 which is transmitted and rotated from the sun gear 29 side. This cylinder 11t1 is made to protrude toward the 18 side.
The planting case 35 is attached to 31a, and the rotating case 22
The planting case 3 passes through the inside of the cylinder shaft 31a.
The base of the camshaft 32 that protrudes into the rotating case 2
The seedling planting device is made up of one g plate 33 fixed to the outer surface of the second planting transmission case side.

Effects and Effects of the Invention According to the present invention, in a structure in which the planting case is attached to the opposite side of the transmission case with the nucleus of the rotating case which is located on the side of the planting transmission rRI+ case and is transmitted and rotated, the cam in the planting case is Since the camshaft 32 to which the camshaft is attached is attached to the thin plate 33 that is fixed to the outer surface of the rotating case on the anti-planting case side, the camshaft does not fall, and moreover,

In the figure, 51 is a ground leveling float in the center, and 52 is a leveling float on both left and right sides.

To explain the operation of the upper side, when seedlings are placed on each seedling mounting table 19a to L9e and each part is rotated by the engine 4, the passenger tractor 1 is propelled by the rotation of the front shaft 2 and the rear shaft 3, and the rice transplanter 1
The load is partially received and towed by the soil leveling floats 51 and 52, and the power is transferred from the PTO shaft 11 via the transmission/drive shaft 12 to the main transmission case 8 side to the planting transmission case 18.
The power is transmitted to the input shaft inside. And the main planting clutch 45
The drive shaft 43 is transmitted and rotated through the drive shaft 43, and the planting drive shaft 23.
23... is rotated. Then, each rotating case 22a
22e rotates, and with this rotation, the counter planetary gear 30.30 is planetarily rotated around the sun gear 29, and the planetary gear 31.31 meshing with this is rotated. Therefore, the metal 60 fixed to the cylindrical shaft 31a integral with the i-star gear 31, 31 by the knot turbine 40
The fixed planting case main body 35 is attached to the rotating case 22a through the
~22e, and the rotating cases 22a~22
Of course, the camshaft 32, 32 which is integral with e is not rotated by the gear 31, so the planting case main body 35 has an eccentric pitch circle of the sun gear 29 with respect to the push-out operation cam 36 fixed to this camshaft 32. Therefore, it is rotated while the circumferential speed fluctuates. Therefore, interlocking rod 3
7 is swung by the cam 36, and the extrusion shaft 38 is moved downward.

Then, the partitioning claw 3 attached to the planting case body 35
The tip side of 9 operates while drawing the planting trajectory (A), and the seedling holder +h
It intervenes one after another from above into the seedling dividing openings 218 to 21e of Di21, and divides the seedlings in the seedling mounting tables 19a to 19e, which reciprocate from side to side, one by one, to the field leveled by the leveling floats 51 and 52. I'm going to plant it. That is, when the seedling extrusion shaft 38 is located above the planting case 35, the seedling is separated from the seedling mounting table, and when the seedling is thrust into the field, a part of the cam floor of the cam 36 and the interlocking rod 37 is separated. When the spring 42 comes off, the seedling is rapidly pushed into the soil.

In this embodiment, since two seedling planting tools 34 are attached to the rotating case 35, seedling planting can be performed at high speed.

When the seedling planting is to be stopped next time, such as when turning, the planting clutch lever 14 is operated to push in the clutch pin 49 via the wire 50, and the driven clutch body 47 is pushed in.
It is only necessary to contact the cam (b) of the fixed position stop E cam 47a. Then, the driven clutch body 47 moves against the spring 48, and the clutch pawl of the driven clutch body 47 is disengaged from the clutch pawl of the drive clutch gear 46, and the rotation of the drive shaft 43 is stopped at that position.

At this time, the fixed position stop cam 47a is connected to one rotating case 3.
Since the number of seedling planting tools 34 corresponding to the number of seedling planting tools 34 attached to the 1
Even though the two seedling planting tools 34 are attached to one rotating case 35, the seedling planting tools 34 split the seedlings from the seedling table and plant them after the stop operation is applied. No unexpected situations occur.

The embodiment of transmission formation shown in FIG.
Planting drive shaft 2 installed at the rear end of a, 18b, 18c
3 is divided into left and right to form 23a and 23b, and these planting drive shafts 23a and 23b are connected by an intermediate pin shaft that is inserted through the axis of the planting drive shaft and can rotate freely, and to this, the same planting drive shafts are attached to the left and right. Claratis Prokera 1 with a single clutch pawl on the phase
