Detailed Description

Referring to fig. 1 and 2, the overall configuration of a rice transplanter 1 as an example of a paddy field working machine will be described. The rice transplanter 1 includes: the traveling machine body 2 and the planting machine 3 attached to the rear part of the traveling machine body 2 travel through the traveling machine body 2 and planting work is performed by the planting machine 3. As the paddy field working machine, as in the case of the rice transplanter 1, any working machine may be used as long as it has a travel machine body and performs a specific work, and a seeding machine, a transplanting machine, a paddy field management working machine, and the like can be cited.

The traveling machine body 2 includes: an engine 4, a transmission 5 that changes the speed of power from the engine 4, a body frame 6 that supports the engine 4 and the transmission 5, front wheels 7 and rear wheels 8 that are driven by the power transmitted from the engine 4 and the transmission 5, and the like.

The power from the engine 4 and the transmission 5 is transmitted to the front axle case 9 and the rear axle case 10, respectively. The front axle box 10 is supported on the front portion of the body frame 6, and the front wheels 7 are supported on both right and left end portions of the front axle box 9. Similarly, the rear axle box 10 is supported at the rear of the body frame 6, and the rear wheels 8 are supported at both right and left ends of the rear axle box 10. The upper portion of the body frame 6 is covered by the pedal 11, and the operator can move on the pedal 11.

The driver seat 12 is disposed at a front-rear middle portion of the travel machine body 2, and is provided with: a steering wheel 13, an operating pedal 14, an instrument panel 15, and the like. The steering wheel 13 and the dashboard 15 are provided with: and a hood 16 that covers the engine 4. The instrument panel 15 is provided with, in addition to the steering wheel 13: various operation tools for operation such as a main gear lever and a furrow stop switch, and a monitoring panel for displaying operation information. Preliminary seedling stages 17 are provided on both front sides of the pedal 11. The preliminary seedling stage 17 is disposed: the right and left opposing positions sandwiching the engine cover 16. The preliminary seedling stage 17 is supported by: a front and rear frame 18 provided upward from a side end of the pedal 11.

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

The planting work machine 3 includes: planting arms 31, planting claws 32, seedling platforms 33, floats 34, and the like. Planting claw 32 is attached to planting arm 31. The planting work machine 3 is driven by a PTO shaft extending rearward from the transmission case 5. More specifically, the power is transmitted from the PTO shaft to the planting transmission case 36 provided in the planting work machine 3 through the planting center case 35, and the power is distributed from the planting transmission case 36 to the planting arms 31 and the planting claws 32.

Planting arm 31 is rotated by power transmitted from planting transmission case 36. The seedling is supplied from the seedling table 33 to the planting claws 32. The planting claws 32 are inserted into the field along with the rotation of the planting arms 31, and the seedlings are planted so as to reach a predetermined planting depth. In the present embodiment, a rotary planting claw is used, but a clutch type planting claw may be used.

The seedling table 33 is formed of a plate-like member, and is disposed so as to be inclined in a front-high and rear-low manner when viewed from the side of the machine body. On the rear surface of the seedling stage 33, in accordance with the number of planting arms (the number of rows of the planting machine), there are formed: a carrying surface for carrying the seedling raising mat. The rice transplanter 1 of the present embodiment is a 6-row rice transplanter, and thus 6 placement surfaces are formed.

Next, the following description is given: an embodiment in which a flat terminal 40 is disposed in the vicinity of a steering wheel 13 of a rice planting machine 1. The tablet terminal 40 is: a general tablet terminal provided with a display device for inputting operations is used, for example, for displaying a travel route when performing automatic travel of the rice planting machine 1 or performing switching operation between automatic travel and manual travel.

The main part of the present invention is explained below. As shown in fig. 3, the tablet terminal 40 is configured to: the steering wheel 13 is provided at a location a laterally of the steering wheel between the engine cover 16 and the right and left preliminary seedling stages 17. That is, the tablet terminal 40 is provided at: on the path between the engine cover 16 and the preliminary seedling stage 17. Further, by disposing the tablet terminal 40 at a position above the lower end position of the instrument panel 15, it is possible to reduce the movement of the line of sight away from various operation tools or monitor panels provided on the instrument panel 15. Accordingly, when the tablet terminal 40 as the driving operation device is introduced, a layout design that is less likely to be fatigued to the driver can be presented. That is, as a reference for setting the tablet terminal 40, it is preferable to set: is located above the lower end position of the dash panel 15.

On the other hand, if the tablet terminal 40 is disposed too far upward, the front view is impaired, and therefore, it is preferable to set the height of the steering wheel 13 not to be greatly increased. That is, from the viewpoint of ensuring visibility and ensuring workability, it is preferable that the installation location a of the tablet terminal 40 is a region extending substantially laterally from the instrument panel 15. Further, by setting the arrangement of the tablet terminal 40 in the side region of the steering wheel 13, the operation of the steering wheel 13 is not hindered.

As described above, since the installation place a of the flat bed terminal 40 is the space between the engine hood 16 and the preliminary seedling table 17, it is necessary to pass the space when replenishing the preliminary seedling mat placed on the preliminary seedling table 17 or when approaching a furrow in front of the rice transplanter 1 and getting on and off from the front side of the body. Thus, in the present embodiment, a supporting structure for supporting the tablet terminal 40 is carefully studied. That is, the following structure is adopted: when the tablet terminal 40 is used, the tablet terminal 40 is disposed at the installation location a, and when not used, the tablet terminal 40 is retracted from the installation location a, so that the space can be made free.

For example, as shown in fig. 4, the support frame 43 has: a joint 41 that can rotate (rotate in the forward and backward directions of the rice transplanter 1) around a shaft (rear frame 18) extending in the vertical direction, and a holding portion 42 that can hold the flat plate terminal 40 are attached to the frame 18 of the preliminary seedling table 17 using the support frame 43, and thus can be switched between a use position, which is disposed at the installation site a, and a retracted position, which is a position retracted from the installation site a. The joint 41 is detachably attached to the frame 18.

The holding portion 42 extends horizontally from the joint portion 41, and includes at the tip of the holding portion 42: and a holder for holding the tablet terminal 40.

Further, the frame 18 is provided with a plurality of fixing holes 44 in the vertical direction, and the vertical position of the tablet terminal 40 can be easily adjusted by selecting any of the fixing holes 44 in the frame 18 of the preliminary seedling stage 17 as the mounting position of the support frame 43 (i.e., the mounting position of the joint portion 41).

As described above, according to the support structure of the present embodiment, the tablet terminal 40 is disposed between the engine hood 16 and the preliminary seedling stage 17 in the left-right direction (installation position a), and thus, when the space needs to be passed through during the work of replenishing the preliminary seedling mat, the space between the engine hood 16 and the preliminary seedling stage 17 can be made free as a passage by folding the support frame 43 to the side of the preliminary seedling stage 17. Accordingly, the front view of the rice transplanter 1 during traveling can be sufficiently secured, and the trouble of moving to the preliminary seedling stage does not occur, so that the tablet terminal 40 as a large-sized display device can be disposed well without lowering the workability.

Further, by attaching the support frame 43 to the frame 18 of the preliminary seedling table 17 having a relatively high degree of freedom in design, the expandability in attaching to the existing model can be improved. Further, since the support frame 43 can be attached to any attachment position on the frame 18, the tablet terminal 40 can be adjusted in the height direction to be disposed at an optimum position in accordance with the physique, posture, or the like of the driver.

In the example shown in fig. 4, the embodiment in which the joint portion 41 that rotates in the front-rear direction is provided on the support frame 43 of the tablet terminal 40 has been described, but the support structure for supporting the tablet terminal 40 is not limited to this as long as the tablet terminal 40 can be moved from the position in the installation location a to the folded position. For example, the support structure may be a multi-joint support structure, and may be attached not to the preliminary seedling stage 17 but to the engine hood 16.

The support structure 50 shown in fig. 5 includes, in addition to the joint portion 41 that rotates in the front-rear direction about the vertical direction and the holding portion 42 that holds the tablet terminal 40: and an inclined part 51 inclined in the front-rear direction with the horizontal direction as the center. By providing inclined portion 51, support structure 50 can support tablet terminal 40 so as to tilt tablet terminal 40. Accordingly, the tablet terminal 40 can be tilted toward the driver, and visibility can be improved. In addition, the inclined portion 51 may be assembled to the holding portion 42.

The support structure 60 shown in fig. 6 includes: a first joint 61 and a second joint 62 that rotate in the front-rear direction with the vertical direction as the center, and a third joint 63 that allows the tablet terminal 40 to freely tilt in the three-dimensional direction. The third joint portion 63 includes a spherical joint member, so that the tablet terminal 40 can be held to be tiltable in three dimensions. In this way, the support structure 60 has 2 joints, i.e., the first joint portion 61 and the second joint portion 62, as joints for position adjustment, and thus the range of position adjustment can be expanded, and the tablet terminal 40 can be disposed at a more appropriate position. In addition, the support structure 60 further includes a third joint 63 as a joint for three-dimensionally tilting the tablet terminal 40. The support structure 60 is arranged to: not only the planar terminal 40 is inclined in the front-rear direction, but also the angle of the planar terminal 40 can be freely adjusted, so that the visibility of the planar terminal 40 as a display device can be improved, and the operability of the rice transplanter 1 can be further improved.

In the above example, the flat bed terminal 40 is attached to the preliminary seedling stage 17 side, but may be attached to the engine hood 16 side. In this case, the same support structure as described above may be employed. Further, it is also possible to provide: the flat terminal 40 is supported from both sides of the preliminary seedling table 17 and the engine hood 16.
