With reference to FIGS. 1 and 2, the overall structure of the rice transplanter 1 which is an example of a power receiving work machine is demonstrated. The rice transplanter 1 is provided with a traveling machine 2 and a planting machine 3 attached to the rear part, and performs planting work with the planting machine 3 while traveling by the traveling machine 2. As the rice harvesting working machine, similarly to the rice transplanter 1, any working machine that performs a traveling body and a specific work may be provided, and a seeding machine, a transplanter, a rice field management working machine, and the like are exemplified.

The traveling body 2 includes an engine 4, a transmission 5 for shifting power from the engine 4, a body frame 6 supporting the engine 4 and the transmission 5, an engine 4 and Front wheels 7 and rear wheels 8 driven by power transmitted from the transmission 5 are provided.

Power from the engine 4 and the transmission 5 is transmitted to the front axle case 9 and the rear axle case 10, respectively. While the front axle case 9 is supported by the front part of the body frame 6, the front wheels 7 are supported at both left and right ends. Similarly, while the rear axle case 10 is supported by the rear portion of the body frame 6, the rear wheels 8 are supported at both left and right ends thereof. The upper part of the body frame 6 is covered with the step 11, and the operator can move on the step 11.

A driver's seat 12 is disposed in the front and middle part of the traveling body 2, and a steering wheel 13, operating pedals 14, a dashboard 15, and the like are formed in front of the driver's seat 12. A steering wheel 13 and a dashboard 15 are formed on a bonnet 16 covering the engine 4 . In the dashboard 15, in addition to the steering wheel 13, operating tools for various operations, such as a front gear lever and a steering stop switch, are arranged and a monitor panel displaying work information. On both sides of the front of the step 11, a preliminary seedling platform 17 is formed. The preliminary seedling mount table 17 is disposed at a left-right facing position with the bonnet 16 interposed therebetween. The preliminary seedling platform 17 is supported by front and rear frames 18 formed upward from the side ends of the step 11 .

The planting machine 3 is connected to the traveling body 2 via a lifting link mechanism 20 . The lifting link mechanism 20 includes a pair of right and left upper and lower links 21 and 22, a lifting cylinder, and the like. The lower link 22 and the upper link 21 are rotated by the lifting cylinder, and the planting machine 3 is moved up and down.

The planting machine 3 includes a planting arm 31, a planting tank 32, a seedling mount 33, a float 34, and the like. The planting tank 32 is attached to the planting arm 31 . The planting implement 3 is driven by a PTO shaft extending rearward from the transmission 5 . More specifically, power is transmitted from the PTO shaft to the planting transmission case 36 formed in the planting machine 3 via the planting center case 35, and from the planting transmission case 36 the planting arm ( 31), power is distributed to the planting tank 32.

The planting arm 31 rotates by the motive power transmitted from the planting transmission case 36. Seedlings are supplied to the planting tank 32 from the seedling mount 33 . With the rotational movement of the planting arm 31, the planting tank 32 is inserted into the field, and seedlings are planted so as to reach a predetermined planting depth. In addition, in this embodiment, although the rotary type planting tank is employ|adopted, you may use a crank type thing.

The seed mounting table 33 is constituted by a plate-like member, and is disposed so as to be inclined upward in a height-to-height bottom when the body is viewed from the side. On the back side of the seedling mount table 33, a mounting surface for mounting seedling mats is formed according to the number of planting arms (the number of rice transplanters). Since the rice transplanter 1 of this embodiment is a rice transplanter of a six-row planting machine, six mounting surfaces are formed.

Next, an embodiment in which the tablet terminal 40 is disposed near the steering wheel 13 of the rice transplanter 1 will be described. The tablet terminal 40 is a general tablet terminal equipped with a display device capable of input operation, and displays a travel route when the rice transplanter 1 automatically travels, for example, or switches between automatic travel and manual travel. to do or do.

Hereinafter, the main part of this invention is demonstrated. As shown in FIG. 3 , the tablet terminal 40 is disposed on the side of the steering wheel 13 in an installation area A between the bonnet 16 and the left and right preliminary seedling mounts 17 . In short, the tablet terminal 40 is installed on the passage between the bonnet 16 and the preliminary seedling mount 17 . In addition, by arranging the tablet terminal 40 above the lower end of the dashboard 15, it is possible to reduce eye movement from various operation tools formed on the dashboard 15 and the monitor panel. In this way, even when introducing the tablet terminal 40 as a driving operation device, it is possible to make a layout that does not easily fatigue the driver. That is, as a criterion for installing the tablet terminal 40, it is preferable to set it above the lower end of the dashboard 15 in consideration of ensuring visibility and affecting driving operation.

On the other hand, if the tablet terminal 40 is disposed too upward, it may affect the front view, so it is not preferable to install the tablet terminal 40 far beyond the height of the steering wheel 13. In short, from the viewpoints of securing visibility and ensuring workability, it is preferable to set the tablet terminal 40 as an area (A) that generally extends from the dashboard 15 toward the side. In addition, by setting the tablet terminal 40 to the side area of the steering wheel 13, the operation of the steering wheel 13 is not obstructed.

As described above, since the installation area A of the tablet terminal 40 is a space between the bonnet 16 and the preliminary seedling mounting table 17, the preliminary seedling mat placed on the preliminary seedling mounting table 17 When adding or bringing the front of the rice transplanter 1 close to the vicinity of the ridge and getting on and off from the body front side, it is necessary to pass through the space. For this reason, in the present embodiment, a support structure for supporting the tablet terminal 40 is being studied. That is, a structure is adopted in which the tablet terminal 40 is placed in the installation area A when in use, and is evacuated from the installation area A when not in use to vacate the space.

For example, as shown in Fig. 4, the joint part 41 and the tablet terminal 40 that can rotate (rotate in the front-rear direction of the rice transplanter 1) around an axis extending in the vertical direction (frame 18 on the rear side). is attached to the frame 18 of the preliminary seedling mount 17 using the support frame 43 having the holding portion 42 capable of holding the , the use position disposed in the installation area A, and the installation area ( It is possible to switch to the retracted retract position from A). The joint portion 41 is attached to the frame 18 in a freely detachable manner.

The holding portion 42 extends from the joint portion 41 in the horizontal direction, and has a holding tool for holding the tablet terminal 40 at its tip.

In addition, a plurality of fixing holes 44 are formed in the vertical direction in the frame 18, and the frame of the preliminary seedling mount 17 ( By selecting an arbitrary fixing hole 44 in 18), 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 bonnet 16 and the preliminary seed mount table 17 in the left-right direction (in the installation area A), and When passing through the space, such as during the seedling addition operation of the seedling mat, the space between the bonnet 16 and the preliminary seedling mounting table 17 is passed by folding the support frame 43 toward the preliminary seedling mounting table 17 side. can be emptied as As a result, the tablet terminal 40 as a large-sized display device can be satisfactorily secured without impairing access to the preliminary seedling mount 17 and without deteriorating workability while sufficiently securing a front view when the rice transplanter 1 is traveling. it is possible to place

In addition, by attaching the support frame 43 to the frame 18 of the preliminary seedling mount table 17 with a relatively high degree of design freedom, expandability with respect to existing models can be improved. In addition, since the support frame 43 can be attached to an arbitrary mounting position of the frame 18, it is better to arrange the tablet terminal 40 in an optimal position according to the driver's physique or posture by adjusting in the height direction. It is made possible.

In the example shown in FIG. 4 , the embodiment in which the joint portion 41 that rotates in the front-back direction is formed in the support frame 43 of the tablet terminal 40 has been described, but as a support structure for supporting the tablet terminal 40 , as long as the tablet terminal 40 can be moved from the position within the installation area A to the folded position, it is not limited to this. For example, it is good also as a multi-joint support structure, and you may attach it not to the side of the preliminary seedling mount table 17, but to the side of the bonnet 16.

The support structure 50 shown in FIG. 5 includes a joint portion 41 that rotates in the forward and backward directions centering on the vertical direction and a holding portion 42 for holding the tablet terminal 40, as well as a front and back rotation centering on the horizontal direction. It is provided with a tilting part 51 that is tilted in the direction. The support structure 50 can support the tablet terminal 40 with a tilt by providing the tilt portion 51 . In this way, the tablet terminal 40 can be tilted toward the driver, and visibility can be improved. In addition, you may insert the tilt part 51 into the holding part 42.

The support structure 60 shown in FIG. 6 can freely tilt the first joint portion 61 and the second joint portion 62 rotating in the forward and backward directions around the vertical direction, and the tablet terminal 40 in a three-dimensional direction. A third joint portion 63 is provided. The third joint portion 63 includes a spherical joint member and holds the tablet terminal 40 so as to be able to tilt in the three-dimensional direction. In this way, the support structure 60 has two joints, the first joint part 61 and the second joint part 62, as joints for position control, so that the range of position control can be widened, and a more appropriate position can be obtained. It becomes possible to place the tablet terminal 40 on the . In addition, the support structure 60 includes a third joint portion 63 as a joint for three-dimensionally stiffening the tablet terminal 40 . The support structure 60 not only tilts the tablet terminal 40 forward and backward, but also has a multi-joint structure capable of freely adjusting the angle of the tablet terminal 40, thereby improving the visibility of the tablet terminal 40 as a display device. It can improve, and by extension the operability of the rice transplanter 1 can be improved.

In addition, in the above example, the tablet terminal 40 is attached to the side of the preliminary seedling stand 17, but it is also possible to attach it to the bonnet 16 side. Even in that case, the same support structure as described above can be employed. Moreover, it is good also as a structure which supports the tablet terminal 40 from both the side of the preliminary seedling mount table 17, and the side of the bonnet 16.
