Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 is a riding four-wheel type traveling vehicle body, and a rice transplanting device 3 is mounted on a rear portion of the traveling vehicle body via a lift mechanism 2 so as to be able to move up and down. The rice transplanter 3 has a frame main body 4 which is also elongated in the left-right direction and also serves as a transmission case, and three side frames 5, 6, 7 extending rearward from the frame main body 4.

A seedling mounting table 8 is supported on the frame body 4 so as to incline in a forward leaning posture and reciprocate in the left-right direction. The side frames 5, 6 and 7 have support shafts 9 having a length substantially the same as that of the frame body 4 below the respective base end portions.
Are pivotally supported along the length direction of the frame body 4, and one end of four connecting arms 10 are fixed to the support shaft 9 at substantially equal intervals. At the other end of these four connecting arms 10,
Three leveling floats 11, 12, 13 are pivotally attached via pins 14. The connecting arms 10 pivotally mount the floats 11 and 13 at the left and right ends thereof and the float 12 at the two inner arms, and do not overlap vertically with respect to the side frames 5, 6 and 7. It is arranged on the support shaft 9 so as to be located laterally, and therefore, the connecting arm 10 and each leveling float 1
The pivot points (fulcrums) of 1,12,13 are also side frames 5,6.
It does not overlap with 7 vertically.

The tips of the side frames 5, 6 and 7 are bent in a plane L shape, and two seedling planting tools 15 are attached to each of the side frames 5 and 7 and one to the side frame 6 at this bent portion. There is. Seedling attachment 15 attached to the side frame 6 in the center
Is mounted at a position where the rear left and right central portion of the leveling float 12 is cut forward by a predetermined width in the left and right, that is, corresponding to a single-row planting groove portion. Further, two seedling planting tools 15 attached to each of the side frames 5 and 7 are provided on each side of the leveling floats 11 and 13.

Each of these seedling planting tools 15 moves up and down so as to face the inclined lower end portion of the seedling placing table 8 and takes out the mat-like seedlings placed on the seedling placing table 8 one by one from the seedling taking-out port. It is designed to be planted on the rice field. And each said leveling float 11,1
The pivotal positions of the connecting arms 10, 10 ... With respect to 2, 13 are slightly rearward of the tips of the seedling planting devices 15, 15 ,.

The leveling floats 11, 12, 13 are provided with a support height adjusting device 16. This adjusting device 16 is attached to the operation arm 17 having one end fixed to the support shaft 9 and the adjustment lever 18 fixed to the other end, and to the side portion of the side frame 6 to which the seedling planting tool 15 is not attached, The adjusting lever 18 is configured to include a shift plate 19 that is vertically displaced and locked, and by moving the adjusting lever 18 up and down along the shift plate 19 and locking the same, the supporting height of the leveling floats 11, 12, and 13 is increased. The height is adjusted at the same time.

Another embodiment of the present invention shown in FIG. 3 is a side frame 6
The tip of each is made into a plane T shape and seedling planting tools 15 are provided on both sides thereof, one seedling planting tool 15 is provided on the side frame 7, and the side frame 7 side opposite to the seedling planting tool 15 is shifted. Board 19
And the same as the embodiment of FIG. 1 except that the adjusting lever 18 is provided.

In the rice transplanter having such a configuration, the rice transplanter 3 is slid on the rice field while being pulled and driven by the traveling vehicle body 1.
Will carry out 5 rice planting operations at once. At the time of this rice planting work, it is necessary to adjust the implantation depth of the seedlings planted by the seedling planting tool 15 depending on the size of the seedlings, the hardness of the rice field, etc., but this adjustment is performed by the support height adjusting device 16.

First, move the adjustment lever 18 along the shift plate 19,
The support shaft 9 is rotated via the operation arm 17. For example, when the adjustment lever 18 is lowered downward in FIG. 2, the support shaft 9 is rotated clockwise, and accordingly, the connecting arm 9 is rotated. 10 also rotates in the same direction and simultaneously pushes down the leveling floats 11, 12, 13 downwards about the pin 14 and separates it from the side frames 5, 6, 7 so that the planting depth of the seedling becomes correspondingly shallow. On the contrary, when the adjustment lever 18 is raised upward, the support shaft 9 rotates counterclockwise, and the leveling floats 11, 12, 13 are raised upward to approach the side frames 5, 6, 7 and The planting depth becomes deep.

When the leveling floats 11, 12, and 13 are moved up and down, in the embodiment, the connecting arm 10 and the connecting position of the connecting arm 10 and the pin 14, that is, the fulcrum of the leveling floats 11, 12, and 13 are the side frames 5, 6, and 7. Since the side frames 5, 6, 7 do not interfere with the vertical movement of the leveling floats 11, 12, 13 since they are located on the side of the plant, the vertical movement range can be widened and the depth of planting of seedlings can be adjusted. The width is getting wider.

Further, since the leveling float 12 is supported by the pair of connecting arms 10 and 10 with the single-row planting groove interposed therebetween, the vertical movement thereof is stably performed. Further, the adjusting lever 18 and the shift plate 19 of the supporting height adjusting device 16, that is, the supporting height adjusting device 16
Is provided in the unused side space of the side frame 6 or 7 and is projected to the rear of the rice planting device 3, so that it is not necessary to separately provide a place for installing the adjusting device 16, and the operation is easy to perform.

〔The invention's effect〕

As described above, according to the apparatus for mounting the leveling float in the rice transplanter of the present invention, the seedling planting equipment 15, 15, ... And the float 11,
12 and 13 are arranged alternately in the width direction and each leveled float 11,1
Since the connecting arms 10, 10 are pivotally supported by the connecting arms 10, 10, ... When adjusting the vertical movement of the ground leveling floats 11, 12, 13, no unbalanced load is applied to the connecting arms 10, 10 ... The support shaft 9 is smoothly rotated, and the leveling performance of each leveling float 11, 12, 13 is improved.

Moreover, since the leveling floats 11, 12, 13 are pivotally attached to the left and right sides near the seedling planting position by the seedling planting tools 15, 15, ..., the floats 11, 12, 13 are moved up and down. When the planting depth is adjusted, the leveling floats 11, 12, 13 will rotate back and forth around the pivotal part, so the seedling planting depth will not change and will be uniform. By eliminating the horizontal inclination of the leveling float 12 having the groove, the seedling planting depth is not varied and the seedling planting performance is improved.
