It has been. The transport stand 45 is made of a plate bent in a U-shape, and thus has left and right leg portions 46 and 46 and a bottom portion 47 connecting the lower ends of these leg portions, and the upper end portions of the leg portions 46 and 46. And is fixed to the bracket 42. As shown in FIGS. 3 to 5, the grounding stand 40 is in the use position and the transportation stand 45 is not usually attached, but the transportation stand 45 is disposed slightly rearward inside the grounding stand 40. . That is, both leg portions 46, 46 of the transport stand 45 are arranged so as to pass through the front portion of the portion C between the left and right floats 16l, 16r and the central float 16c. The mounting of the transportation stand 45 is not limited to the bracket 42 for the vertical frame 43 but may be another frame body.

  Since the stand 22 of the passenger rice transplanter 1 has the above-described configuration, it is in a state in which the transportation stand is removed as shown in FIG. 6 except during transportation. When the planting operation is paused or stored, the stand rod 37 is positioned and fixed at the lowered use position. That is, the positioning pin 33 is inserted into the pin hole 44 above the stand rod 37 and the pin hole of the support cylinder 32 and positioned. In this state, the left and right stand rods 37, 37 are located slightly in front of the inner corners of the left and right floats 16l, 16r, and the ground plate 41 at the lower end thereof is grounded with a relatively wide space in the left-right direction. Thus, the planting device 9 is stably supported.

  When the riding rice transplanter 1 is used for planting, the positioning pin 33 moves against the spring 39 and is pulled out from the pin hole 44 above the stand rod 37, and the stand rods 37, 37 are moved upward (see FIG. 7). In the vicinity of the upper limit position where the rising portion of the ground plate 41 contacts the support cylinder 32, the positioning pin 33 is inserted into the pin hole of the support cylinder 32 and the storage pin hole 38 of the stand rod 37. Thereby, the stand rod 37 is positioned and fixed at the storage position which is the upper position and stored.

  When the passenger rice transplanter 1 is transported on a loading platform such as a truck, the transport stand 45 is attached to the frame body 42 with bolts 50 as shown in FIG. At this time, if the stand rod 37 is moved downward to keep the grounding stand 40 in use, the work becomes easy. Then, the positioning pin 33 is removed from the pin hole 44 which is the use position, the stand rod 37 is moved upward, and the pin 33 is inserted into the storage pin hole 38 to be positioned. In this state, the transport stand 45 has both legs 46, 46 located at the front of the portion C between the central float 16c and the left and right floats 16l, 16r, and without interfering with the float 16 or the like. Support. The transport stand 45 includes a bottom portion 47 that connects the lower ends of both leg portions 46, 46, and the upper portion of the leg portion 46 is fixed to a bracket 42 for fixing the vertical frame 43, and has a high strength consisting of a frame structure. Even if an impact acts during transportation, the planting device 9 is stably supported. Moreover, since the said transport stand 45 is attached only at the time of transport, it does not interfere with the fertilization nozzle 17, the leveling device 20, etc., and supports the planting apparatus 9 stably, without hitting a loading platform etc.

  The stand 22 such as the stand rod 37 is disposed in the vicinity of the portion C between the central float 16c and the left and right floats 16l and 16r in the front part of the left and right planter cases 30, and effectively uses a narrow space where various devices are congested. It is arranged using. Even when the ground plate 41 having a predetermined length may interfere with the cover 21a of the leveling roller 21 or the like when the stand rod 37 is moved to the raised storage position or the lowered use position, the stand rod 37 is rotated. Thus, the ground plate 41 can be moved while avoiding interference with the roller cover 21a.

  The riding rice transplanter 1 is a 4-row planting rice transplanter, but the stand 22 is not limited to 4-row planting but can be applied to a 4-plant or more multi-planting rice transplanter. Moreover, although the said stand 22 was applied and applied to the riding rice transplanter, it is applicable not only to this but another transplanter similarly.
