The seedling mount 33 is configured by a plate-like member, and is disposed so as to be inclined in a front-to-back direction and a low state in a side view of the body. On the rear surface of the seedling mount 33, a mounting surface on which the seedling mat is placed is formed according to the number of planting arms (the number of rice transplanters). Since the rice transplanter 1 of this embodiment is a six-planted rice transplanter, six mounting surfaces are formed.

Next, an embodiment in which the tablet terminal 40 is arranged near the steering handle 13 of the rice transplanter 1 will be described. The tablet terminal 40 is a general tablet terminal provided with a display device capable of input operation. For example, when the rice transplanter 1 performs automatic traveling, a traveling route is displayed, or switching operation between automatic traveling and manual traveling is performed. It is something to do.

Hereinafter, the main part of the present invention will be described. As shown in FIG. 3, the tablet terminal 40 is disposed on the side of the steering handle 13 and in the installation area A between the bonnet 16 and the spare seedling stage 17 on the left and right sides. That is, the tablet terminal 40 is installed on the path between the bonnet 16 and the spare seedling stage 17. Moreover, the tablet terminal 40 can arrange | position upward from the lower end position of the dashboard 15, and can reduce the eyes | visual_axis movement from the various operation tools and monitor panel which were provided on the dashboard 15. FIG. Thereby, when introducing the tablet terminal 40 as a driving | operation operation apparatus, it can be made the layout which is hard to get tired for a driver | operator. That is, as a guideline for installing the tablet terminal 40, it is preferable to set the tablet terminal 40 above the lower end position of the dashboard 15 in consideration of ensuring visibility and influence on driving operation.

On the other hand, if the tablet terminal 40 is disposed too far, it may affect the front vision, so that it is not preferable to install the steering terminal 13 far beyond the height. That is, from the viewpoint of ensuring visibility and ensuring workability, it is preferable that the installation area A of the tablet terminal 40 is an area that extends approximately from the dashboard 15 to the side. In addition, by disposing the tablet terminal 40 in a lateral region of the steering handle 13, the operation of the steering handle 13 is not hindered.

As described above, the installation area A of the tablet terminal 40 is a space between the bonnet 16 and the spare seedling stage 17, so when adding the spare seedling mat placed on the preliminary seedling stage 17, When getting in and out of the front of the aircraft with the front of the aircraft 1 approaching the heel, it is necessary to pass through the space. For this reason, in this embodiment, the support structure which supports the tablet terminal 40 is devised. In other words, the tablet terminal 40 is arranged in the installation area A when it is used, and is retracted from the installation area A when the tablet terminal 40 is not used so that the space can be opened.

For example, as shown in FIG. 4, the holding portion that can hold the joint portion 41 and the tablet terminal 40 that can be rotated (rotated in the front-rear direction of the rice transplanter 1) around a vertically extending axis (the rear frame 18). By using the support frame 43 having the part 42 and attaching it to the frame 18 of the preliminary seedling stage 17, it is possible to switch between the use position arranged in the installation area A and the retreat position retracted from the installation area A. is there. The joint portion 41 is detachably attached to the frame 18.
The holding part 42 extends in a horizontal direction from the joint part 41 and has a holding tool for holding the tablet terminal 40 at the tip thereof.

Further, a plurality of fixing holes 44 are provided in the frame 18 in the vertical direction, and an arbitrary fixing hole 44 of the frame 18 of the preliminary seedling stage 17 is selected as the mounting position of the support frame 43 (that is, the mounting position of the joint portion 41). Thus, it is possible to easily adjust the vertical position of the tablet terminal 40.

As described above, according to the support structure of the present embodiment, the tablet terminal 40 is disposed between the left and right directions of the bonnet 16 and the spare seedling stage 17 (installation area A), and the seedling work of the spare seedling mat is performed. When passing through the space, the space between the bonnet 16 and the spare seedling stage 17 can be made as a passage by folding the support frame 43 toward the spare seedling stage 17. Accordingly, the tablet terminal 40 as a large-sized display device can be secured without deteriorating the access to the spare seedling stage 17 while reducing the workability, while ensuring a sufficient front view when the rice transplanter 1 is traveling. It is possible to arrange well.

Furthermore, the expandability to the existing model can be improved by attaching the support frame 43 to the frame 18 of the spare seedling stage 17 having a relatively high degree of design freedom. Further, since the support frame 43 can be attached to any attachment position of the frame 18, the tablet terminal 40 is arranged at an optimum position according to the physique and posture of the driver by adjusting in the height direction. It is possible.

In the example illustrated in FIG. 4, the embodiment in which the support frame 43 of the tablet terminal 40 is provided with the joint portion 41 that rotates in the front-rear direction has been described. However, as the support structure that supports the tablet terminal 40, the tablet terminal 40 is installed. As long as it can move from the position in the area A to the folded position, it is not limited to this. For example, it may be a multi-joint support structure, or may be attached to the bonnet 16 side instead of the spare seedling stage 17 side.

The support structure 50 shown in FIG. 5 includes a tilt part 51 that tilts in the front-rear direction around the horizontal direction, in addition to the joint part 41 that rotates in the front-rear direction around the vertical direction and the holding part 42 that holds the tablet terminal 40. Is provided. Since the support structure 50 includes the tilt part 51, the tablet terminal 40 can be tilted and supported. Thereby, the tablet terminal 40 can be tilted toward the driver, and visibility can be improved. Note that the tilt unit 51 may be incorporated in the holding unit 42.

A support structure 60 shown in FIG. 6 includes a first joint 61 and a second joint 62 that rotate in the front-rear direction around the vertical direction, and a third joint 63 that can tilt the tablet terminal 40 freely in a three-dimensional direction. And comprising. The third joint portion 63 includes a spherical joint member, and holds the tablet terminal 40 so as to be tiltable in a three-dimensional direction. Thus, the support structure 60 has two joints of the first joint portion 61 and the second joint portion 62 as joints for position adjustment, so that the range of position adjustment can be expanded and more appropriate. It becomes possible to arrange the tablet terminal 40 at the position. At the same time, the support structure 60 includes a third joint portion 63 as a joint for tilting the tablet terminal 40 three-dimensionally. The support structure 60 not only tilts the tablet terminal 40 in the front-rear direction but also has a multi-joint structure that can freely adjust the angle of the tablet terminal 40, thereby improving the visibility of the tablet terminal 40 as a display device. As a result, the operability of the rice transplanter 1 can be improved.

In the above example, the tablet terminal 40 is attached to the spare seedling stage 17 side, but it can also be attached to the bonnet 16 side. In this case, the same support structure as described above can be adopted. Furthermore, it is good also as a structure which supports the tablet terminal 40 from both the preliminary seedling stand 17 side and the bonnet 16 side.

The present invention can be used for a paddy field work machine in which a display device is newly arranged near the steering handle.
