In the rice transplanter installed in the left and right machines, the outer hoppers (371) (372) and the feeding case (381) (382) are detachably attached, and the left and right machine outer hoppers (371) (372) and the feeding case (381) ( 382) is stored inside the traveling vehicle (1) to reduce the left and right width, and the traveling vehicle (1) can be transported without removing the fertilizer (36), and the hopper (371) (372) outside the left and right devices ) And the feeding case (381) (382) can be easily transferred to the fertilization work position or the storage position, the fertilizer (36) is installed in the traveling vehicle (1), and the fertilizer (36) is provided with an air tank. (42) 421) (422) are provided, and supply air for conveying the fertilizer delivered from the feeding cases (38) (381) (382) is supplied from the air tanks (42) (421) (422) and extends in the left-right direction. The left and right air tanks (421) and (422) are rotatably provided at the end of the central air tank (42) to be turned, and the left and right air tanks (421) and (422) are folded to fold the left and right full widths of the air tanks (42), (421) and (422). This reduces the problem of causing the air tanks (421) and (422) to collide with a truck bed during transportation. Further, an auxiliary step (125), which is a stage for supporting the removed hoppers (371) (372) and the feeding cases (381) (382) outside the left and right machines, is provided on the traveling vehicle (1), and the removed hopper (371 ) (372) and the feeding case (381) (382) do not need to be transported alone, the handling operation of the hopper (371) (372) and the feeding case (381) (382) is simplified, and in the middle of transportation. It is configured so that breakage can be easily prevented.
[0028]
Furthermore, as shown in FIG. 25, when removing the left and right feeding cases (381) and (382) to reduce the left and right width of the fertilizer section (36), the conveyance hoses (40) and (40) outside the left and right machines are connected to the joint (69 The left and right air tanks (421) and (422) are folded with the joints (69) and (69) attached to the left and right air tanks (421) and (422). The end of the removed transfer hose (40) is detachably engaged and supported by the pin (142) in the opening (141) of the auxiliary seedling mounting table (140) on the upper end side, and the seedling mounting table (16) is supported. The side marker (145) is detachably locked to the support column (143) via the marker hook (144), and the hose hook (146) is fixed to the marker hook (144) to remove the transport hose (4 ) Is configured so as to lock the support to the intermediate said hose hook (146).
[0029]
As is clear from the above, a receiving member (146) for removing the conveying hose (40) for conveying fertilizer and supporting it at the position is provided in the planting part (15), and the conveying hose (40) is separated from the fertilizer (36). Even if it carries out, it can carry out accommodation support of the planting part (15) easily by the auxiliary seedling mounting stand (146) which is a receiving member, and can prevent easily that a conveyance hose (40) is damaged at the time of transport. At the same time, an auxiliary seedling stand (140) or a hose hook (146) is provided in the entire left and right width when the right and left widths of the planting part (15) and the air tanks (42), (421) and (422) are reduced. The removal end of the transfer hose (40) can be accommodated within the entire left and right width of the planting part (15) by folding the left and right ends of the platform (16) to reduce the left and right width. Prevents contact with the loading platform and damage It is sea urchin configuration.

【The invention's effect】
The invention of claim 1 As is apparent from the above examples, the rice transplanters providing a fertilizer portion which are juxtaposed a plurality of sets of hoppers and feeding the case in the lateral direction to the traveling vehicle, positioned outside the left and right sides of the vehicle The pair of the hopper and the feeding case to be attached are detachably attached to the pair of the hopper and the feeding case adjacent thereto by bolts, and the left and right outer hoppers and the feeding case are set on the left and right sides of the traveling vehicle. A platform for mounting is provided so as to be located inside the set of the left and right outer hoppers and the feeding case when in the fertilization work position, and each of the platforms has the left and right outer hoppers and the feeding case. The bolt that fastens the set and the set of the hopper and the feeding case adjacent to the set is configured to fix the set of the left and right outer hoppers and the drawing case after the removal. It is.
According to this structure, remove the set of the left and right outboard of hot Pas及 beauty feeding case, the lateral width of the fertilizer portion can decrease low, Ru can carry vehicle without removing the fertilization unit.
In addition, each pedestal provided in the traveling vehicle has left and right outer hoppers after being removed by the bolts that fasten the left and right outer hopper and feeding case groups and the adjacent hopper and feeding case group. Since the set of the feeding case is fixed, there is no need to transport the left and right outer hoppers and the feeding case set separately, and the handling operation of the hopper and the feeding case set can be simplified. There is an effect that it is possible to easily prevent damage during transportation.
[0031]
Further, with the invention of claim 2, it is So設fertilization portion traveling vehicle, provided Eatan click fertilization unit, supplying Eatan click or al a carrier air for conveying the manure delivered feeding cases or al, those in Eatan click end of the central that extends in the lateral direction is provided right and left Eatan click rotatably, by scaled down the left and right entire width of the entire air tank folded left and right Eatan click, during transportation truck bed, etc. an effect that can eliminate the problem of colliding a lateral Eatan click on.
