Subsequently, a known individual seedling separation / sorting and feeding mechanism,
That is, the row-shaped seedlings fed from the row-shaped seedling separating mechanism h are separated into individual seedlings, sorted into good seedlings and bad seedlings, and only good seedlings are sent to the seedling planting mechanism in the next stage. The individual seedling separation / sorting and feeding mechanism k is replaced by the transplanter chassis c having the above-mentioned configuration.
I will explain the situation installed in.

The individual seedling separation / sorting and feeding mechanism k has the above-mentioned 4
The row seedling separating mechanism h of the stand is provided in a 1: 1 relationship, and the row seedlings fed from the row seedling separating mechanism h are conveyed to the individual separating section 29. An individual that receives the seedlings individually separated by the horizontal conveyor 30 and its individual separating unit 29, sorts them into good seedlings and bad seedlings while transporting them, and sends only the good seedlings to the vertical sandwiching conveyor 31. It is composed of a seedling transfer and selection conveyor 32 (FIG. 5).

This individual seedling separation / sorting and feeding mechanism k mounts the transmission 33, which drives each of the above-mentioned conveyors, by attaching members 34 and 34 'to the front lateral member 6 of the upper machine casing b and the lower machine casing a. It is attached to and supported by the front frame 3 .

In the row-shaped seedling horizontal transfer conveyor 30, the row-shaped seedling receiving side conveyor frame 30 'is separated from the individual separating section 29.
With respect to the conveyor frame 30 ″ on the side, a new configuration is provided in which the horizontal bending shaft 35 is bent upright at a right angle to stand up and maintain that state (FIG. 4, FIG.
5). Usually, the above-mentioned conveyor frame 3 on the row-side seedling receiving side
0'is laid below the space j formed between the row-shaped seedling separating mechanisms h, h as described above, and stands up in the space j due to the bending. It is set at a required relative position along the side surface of the moved row-shaped seedling separating mechanism h (Figs. 3 to 5).

Next, the seedling planting mechanism m which constitutes the transplantation unit together with the above-mentioned row-shaped seedling separating mechanism h and the individual seedling separating and selecting and feeding mechanism k will be described.

The seedling planting mechanism m is a front end of a movable frame n which is rotatably supported at its front end with respect to a traction drive shaft 36 horizontally extending in parallel with the front frame 3 of the lower machine frame a of the transplanter chassis c. The rolling corta n'is pivotally supported on the
The grooving device 37 and the planting wheel 38 are pivotally supported 38 ',
A pair of left and right compression wheels 41, 41 are pivotally supported on a compression wheel bracket 40 attached so that the relative relationship with the movable frame n can be adjusted up and down by operating the implantation depth adjustment handle 39.
The planting wheel 38 releases the seedling p received from the vertical sandwiching conveyor 31 into the groove created by the grooving device 37, and the compression wheel 41.
Is to be planted continuously by suppressing the surrounding soil, and in this respect, the seedling planting mechanism m is the same as the conventionally known seedling planting mechanism.

However, first, the seedling planting mechanism m is as follows.
Instead of hoisting the rear side on the upper machine frame b of the transplanter chassis c with a spring, on the contrary, the spring is made to act within the set range so as to follow the height of the field, and secondly, This is new in that neither the row-shaped seedling separating mechanism h nor the individual seedling separating and feeding mechanism k is mounted.

Now, this point will be described in more detail. Four
2 is an inverted L-shaped bracket attached to the compression wheel bracket 40, 43 is a pivot attached to the pivot pot bracket 44 attached to the intermediate horizontal member 8 of the upper machine frame b, and 45 is the inverted L-shaped bracket 42. Horizontal piece 42 '
It is inserted from below and is suspended by a suspension nut 46 on the pivot 43 by a suspension bolt, and a required margin s'is held between the bolt head 45 'and the horizontal piece 42'. Reference numeral 47 denotes a regulation tube fitted to the hanging bolt 45 above the horizontal piece 42 ', and 48 denotes this regulation tube 4
7 is an upper limit setting nut that is screwed into the suspension bolt 45 on the upper side of 7, and holds a required margin s ″ between the upper limit setting nut 48 and the restriction cylinder 47. 4
Reference numeral 9 is a compression spring fitted to the suspension bolt 45 in a state in which the restriction cylinder 47 and the upper limit setting nut 48 are included, 50 is a compression spring adjustment handle, and 51 is a cover cylinder.

As described above, the movable frame n of the seedling planting mechanism m holds the required margin s ″ between the upper limit setting nut 48 and the regulating cylinder 47, so that the traction drive shaft 36 is centered. Further, the rear side thereof can be raised and rotated within the range of the margin s ″ while maintaining the relative relationship between the grooving device 37, the planting wheel 38, and the compression wheel 41.
Since a required margin s'is held between the second horizontal piece 42 'and the bolt head 45', the rear side of the traction drive shaft 36 is the center, and the rear side of the grooving device 37, the planting wheel 38, and the crusher are compressed. While maintaining the relative relationship of the wheels 41, the wheels 41 can be rotated downward in the range of the margin s'.

The upward or downward rotation of the movable frame n, that is, the vertical rotation occurs in response to ups and downs or unevenness of the field, and the seedling p is attached to the planting wheel 38 of the seedling planting mechanism m.
The vertical sandwiching conveyor 31 of the above-mentioned individual seedling separation / selection feeding mechanism k that is delivered is mounted on the transplanter chassis c. Therefore, depending on the size of the vertical rotation, the planting wheel 38 and the vertical sandwiching conveyor 31 are provided. There is a possibility that an appropriate correspondence relationship of the delivery part of the conveyor 31 may be broken, and delivery of the seedling p may be hindered.

However, according to the seedling planting mechanism m having the above construction, the planting wheel 38 is moved to the seedling wheel 38 by moving the suspension bolt 45 up and down with respect to the pivot 43 by the suspension nut 46 according to the situation in the field. The receiving opening can be adjusted so as to always face the seedling delivery portion of the vertical sandwiching conveyor 31,
The seedling p can be delivered properly.
