There was a problem that the number of seedlings was different for each planting article.

[Technical means for solving problems]

In order to solve the above-mentioned problems of the conventional art, the present invention provides a drive shaft 28 rotatably provided in a transmission case 19.
The rotary case 29 is attached to the rotary case 29, and an implanter drive shaft 34 rotated by the transmission mechanism A provided in the rotary case 29 is provided on the distal end side of the rotary case 29.
In the transplantation device in which the main body of the transplantation instrument 35 is attached to 4, the engaging pawl 31a is provided on the sun transmission member 31 of the transmission mechanism A,
A member 3 having an engaging claw 30c that engages with the engaging claw 31a.
0 is provided in the transmission case 19 so as to be rotationally adjustable and fixed, and the engaging portions of the engaging claws 31a and 30c are arranged in a portion sealed by an oil seal 46 provided between the case and the member 30. It is a device.

〔The invention's effect〕

According to this invention, the sun transmission member 31 of the transmission mechanism A can be rotationally adjusted through the engaging claws 30c and 31a by the member 30 which is provided on the transmission case 19 so as to be rotationally adjustable. The posture can be easily adjusted, and even if the posture of the implant is different for each implant due to part processing errors and assembly errors, the posture of the implant of each implant can be easily corrected to the same level. It is possible to solve the problem of the conventional example that the number of planted seedlings differs for each article.

The member 30 and the sun transmission member 31 are engaged with each other by the engaging claw 30.
Since they are connected via c and 31a, it is possible to easily assemble the respective members and the rotary case 29 to the machine body. Further, since the engaging portions of the engaging claws 31a and 30c are arranged in the portion sealed by the oil seal 46 provided between the case and the member 30, foreign matter such as mud in the engaging portions is caught. To avoid abnormal wear,
With a simple structure, proper seedling planting work can be performed over a long period of time.

Next, the operation of the above example will be described. When seedlings are placed on the seedling tank 20 and each part is rotated by the engine 10, the passenger towing vehicle 1 is propelled by the rotation of the front wheels 5 and the rear wheels 7, and the transplanter 1
The eight parts are partially loaded by the leveling floats 22, 23, 23 and pulled, and the power is transmitted from the front transmission case 3 side to the input shaft in the transmission case 19 via the transmission shaft. In this way, the power is transmitted from the input shaft in the transmission case 19 to the drive shaft 28 via an appropriate transmission route. Then, each rotating case 29 rotates, the counter planetary gears 32, 32 are planetarily rotated around the sun gear 31, and the planetary gears 33, 33 meshing with the counter planetary gears 32 are rotated. Therefore, the implanter drive shaft 3 provided integrally with the planetary gears 33, 33 is provided.
The implant main body 35a is rotated via the attachment 4 and the mounting bracket 42. In addition, the cam body 39 integrally attached to the rotating case 29 via the boss portion 39a is rotated while being displaced with respect to the rotation of the implant body 35a. The seedling pushing fork 37 is moved up and down.

That is, the tip side of the seedling dividing claw 36 operates along the transplanting locus P, and the seedlings to be fed to the seedling dividing ports 27, 27, ... The seedlings are forcibly transferred one after another, and when the seedling splitting claws 36 plunge into the soil surface at the lowermost end (at the position P1), the seedling pushing fork 37 just pushes down the seedlings by the action of the spring 40 to transplant.

Then, when there is a difference in the amount of seedlings split by the seedling splitting claws 36, 36 of the two transplanters 35, 35 attached to the rotating case 29 due to a processing error or an assembly error of the parts, or the seedling transplanting posture is bad. , The implant main body 35a is rotationally adjusted with respect to the implant drive shaft 34, and the two implants 35, 35
It is advisable to adjust the size and the intervention angle of each of the seedling splitting claws 36, 36 that intervene in the seedling splitting mouth 27 so that they are the same. For this adjustment, loosen the bolts 43 and attach the mounting bracket 4
The attachment angle between the implant body 2 and the implanter body 35a may be adjusted, but since this adjustment can be performed outside the implanter body 35a, the operation is extremely easy.

Further, when the seedling dividing claw 36 is displaced laterally with respect to the seedling dividing opening 27 of the seedling receiving plate 26 during seedling division, the cotter pin 44 is loosened and the transplant tool body 35a is appropriately moved in the axial direction. Then, the cotter pin 44 may be driven again for adjustment.

Further, the two implanters 3 attached to the rotating case 29
After adjusting the tip of each of the seedling dividing claws 36 and 36 of 5, 35 to draw the same locus P as described above, this time, each locus P of each planting article is changed to each seedling dividing port. The members 30 ... Of the rotating cases 29 ... so that they are the same for 27 ...
The bolts 30b ... Are loosened and the arm 30d of the member 30 is held to rotate and adjust the member 30 so that the loci P are the same, and then the bolts 30b are tightened again. By doing so, all the transplanting tools 35 for each planting article have the same locus with respect to the respective seedling dividing ports 27, so that the amount of seedlings is all the same, and good seedling planting work can be performed.
