[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in Fig. 1 to Fig. 5, a riding type rice transplanter 1 as a transplanter has a traveling body 4 supported by front wheels 2 and rear wheels 3, and a center pole 5 is provided in front of the traveling body 4, and an engine E (see Fig. 4) covered by a bonnet cover 6 is mounted on it. Behind the bonnet cover 6, a driving operation section 9 is provided, which includes a steering wheel 7 and a driver's seat 8 where an operator sits. In addition, a planting work machine 11 is connected to the rear of the traveling body 4 via a lifting link mechanism 10 so that it can be raised and lowered.
[0010] The planting machine 11 has a seedling platform 12 on which mat seedlings are placed, and a planting device 13 that picks up the seedlings from the seedling platform 12 and plants them in the field, and below the planting device 13 are multiple floats 15 for leveling the field. One of these multiple floats 15 is a sensing float that controls the elevation of the planting machine 11 according to the field conditions during work and adjusts the planting depth.
[0011] The power of the engine E, which serves as a drive source that outputs driving force, is transmitted to the rear wheels 3 via a rear axle case (not shown) disposed between the rear wheels 3, and is then transmitted to the planting machine 11 via a planting clutch (not shown). This drives the planting machine 11, and the planting device 13 picks up one seedling per plant from the mat of seedlings on the seedling carrying table 12 and transplants them continuously into the field.
[0012] As shown in Fig. 4, the bonnet cover 6 is supported rotatably about a rotation shaft 6a extending in the left-right direction, and is configured to be movable between a closed position (position shown in Fig. 5) that covers the engine E and an open position (position shown in Fig. 5) that exposes the engine E. By opening the bonnet cover 6 from the closed position to the open position, it is possible to access the engine room ER around the engine E, and maintenance inside the engine room ER can be performed.
[0013] In addition, on both the left and right sides of the planting machine 11, there are provided line-drawing markers 16 that draw a travel indicator (travel reference line) in the field for the next planting process by swinging them out to the unplanted side of the field, and the line-drawing markers 16 are configured so that they can be raised and lowered between the swing-out position and the storage position by a marker motor (not shown). Note that by running the rice transplanter 1 with the center pole 5 aligned with the travel indicator formed by the line-drawing marker 16 located at the swing-out position, it becomes easy to move the rice transplanter 1 in a straight line.
[0014] As shown in Figures 2, 6(a) and 6(b), 7 and 9, a display panel 20 is disposed below the steering wheel 7, and a pair of left and right direction lamps 21L and 21R, a fuel gauge 21a as a fuel indicator showing the remaining fuel level, and the like are disposed on the display panel 20. An operation panel 30 is disposed behind the display panel 20. A main shift lever 31 is disposed to the left of the operation panel 30, and an auxiliary shift lever 32 and an engine control lever 33 are disposed to the right of the operation panel 30. A combination switch 34 capable of operating the headlights, horn and direction indicators of the traveling body 4 is disposed in front of the main shift lever 31.
[0015] The main speed change lever 31 can be operated forward and backward to change the traveling speed of the traveling body 4 steplessly, and has forward, neutral, and reverse speed change regions. The sub-speed change lever 32 can be operated forward and backward to change the traveling speed of the traveling body 4 in two stages, and can be positioned at one of a working position selected when performing planting work in a field, a traveling position selected when traveling on a paved surface, and a neutral position. The engine control lever 33 can be operated forward and backward to adjust the rotation speed of the engine E.
[0016] On the operation panel 30, a switch assembly 35 having a plurality of switches and LED lamps, a starter switch 36 for starting the engine E, a jog dial switch 37, etc. are arranged. The jog dial switch 37 is operated by the operator when adjusting and confirming various settings displayed on the display panel 20.
[0017] In addition, a work machine operation lever 28 that protrudes to the right from the side surface of the steering column cover is provided between the starter switch 36 and the jog dial switch 37. The work machine operation lever 28 is configured to be tiltable in the vertical and longitudinal directions, is biased to a neutral position by a biasing member (not shown) or the like, and is configured to return to the neutral position after being tilted in the vertical or longitudinal directions.
[0018] The switch assembly 35 is provided with a planting switch 35a and an automatic planting switch 35b. When the planting switch 35a is pressed and turned ON, each part related to the planting work is activated. That is, when the planting switch 35a is ON, the work machine operation lever 28 is operated in the up and down direction to raise and lower the planting work machine 11, raise and lower the line drawing marker 16, and turn on and off the planting clutch that disconnects the power transmission from the engine E to the planting work machine 11. When the planting switch 35a is OFF, the work machine operation lever 28 is operated in the up and down direction to raise and lower the planting work machine 11. The direction lamps 21L and 21R indicate the direction of the line drawing marker 16 when the planting switch 35a is ON, and indicate the direction of the rotation of the rice transplanter 1 when the planting switch 35a is OFF.
[0019] In addition, the automatic planting mode is turned on and off by pressing the automatic planting switch 35b. When the automatic planting mode is ON, a series of operations performed when the rice transplanter 1 turns is performed automatically. For example, when the automatic planting mode is ON and the steering wheel 7 is rotated a predetermined angle or more, the control unit of the rice transplanter 1 determines that the rice transplanter 1 has started turning. When the control unit determines that the rice transplanter 1 has started turning, the planting clutch is disengaged and the planting implement 11 rises. Then, when the rice transplanter 1 finishes turning, the planting implement 11 descends and the planting clutch is engaged.
[0020] In addition, a navigation system is provided as an option for the rice transplanter 1, and the navigation system can be retrofitted to the rice transplanter 1. The navigation system is composed of a positioning device that measures the position and direction of the rice transplanter 1 using a Global Navigation Satellite System (GNSS), a steering unit that automatically steers the front wheels 2 by controlling the steering operation of the steering wheel 7 with a motor or the like, and a tablet terminal 100 (see FIG. 12).
[0021] For example, the positioning device is fixed to the frame of the traveling machine body 4, and the steering unit is stored in a steering column cover located below the steering wheel 7. Note that instead of a tablet terminal as a mobile terminal, a smartphone or a smart watch may be applied. Also, navigation software is pre-installed on the tablet terminal.
[0022] By starting the navigation software on the tablet terminal, the guidance screen shown in Fig. 8 can be displayed. As shown in Fig. 8, the guidance screen displays a mark 87a indicating the vehicle's position, as well as the satellite reception status, a compass indicating the direction, a route error 87b, a working distance and area, a satellite reception status, etc., and also includes a point A generation button 87c, a point B generation button 87d for route generation, a reset button for resetting the route using the current position as the reference position, a route correction button, a tracking ability button, etc.
[0023] When the automatic planting mode is ON, the steering unit controls the steering wheel 7 so that the rice transplanter 1 travels straight along a straight, linear path set using the navigation system. For example, when the operator operates the A point generation button 87c and the B point generation button 87d during teaching travel to determine the reference line of the work path, the rice transplanter 1 obtains position information and direction information of the positions where these buttons are operated, and determines the reference line. Then, the linear path along which the rice transplanter 1 travels back and forth is determined along the reference line.
[0024] 2, 9 and 10, a tablet holder 40 is provided between the display panel 20 and the steering wheel 7. The tablet holder 40 is detachably supported by a panel cover 41 of the traveling body 4 with a knob bolt, a screw or the like. The tablet holder 40, which serves as a holding member and a cover, has a flat portion 42, and a plurality of (four in this embodiment) protruding portions 43, 44, 45, 46 protruding upward from the flat portion 42, and positioning portions 47L, 47R, 48L, 48R.
[0025] The flat surface 42 is formed on a flat plane and is inclined at a predetermined angle with respect to the horizontal plane. The protruding portions 43, 44, 45, 46 are formed to have a substantially triangular cross section, and the upper surfaces of these protruding portions 43, 44, 45, 46 form flat placement portions 43a, 44a, 45a, 46a on which the tablet terminals are placed. The positioning portions 47L, 47R position the tablet terminals in the left-right direction by restricting the left-right movement of the tablet terminals placed on the placement portions 43a, 44a, 45a, 46a. The positioning portions 48L, 48R abut against the lower portions of the tablet terminals placed on the placement portions 43a, 44a, 45a, 46a, thereby holding the tablet terminals and positioning the tablet terminals in the front direction (rear direction).
[0026] As described above, the flat portion 42 is inclined at a predetermined angle with respect to the horizontal plane, and the placement portions 43a, 44a, 45a, 46a also extend parallel to the flat portion 42. Therefore, the tablet terminals placed on the placement portions 43a, 44a, 45a, 46a abut against the positioning portions 48L, 48R due to their own weight, and are held by the placement portions 43a, 44a, 45a, 46a and the positioning portions 48L, 48R.
[0027] As shown in Figs. 10 and 11, a panel cover 41 serving as a cover member is provided with a substantially rectangular maintenance opening 41a, and the maintenance opening 41a communicates with the engine room ER through a space within the panel cover 41. Here, as shown in Fig. 4, a radiator 50 for cooling the engine E is disposed behind the engine E in the engine room ER. The radiator 50 is provided with fins through which the cooling water heated by cooling the engine E circulates, and the cooling water is cooled by cooling the fins with a cooling fan or outside air. As shown in Fig. 11, a water supply port 51 for supplying the cooling water to the radiator 50 is provided at a position facing the maintenance opening 41a. The water supply port 51 is covered by a water supply cap 51a, and when supplying the cooling water from the water supply port 51, the water supply cap 51a is removed. Note that even if the maintenance opening 41a is covered by the water supply cap 51a, it still faces the maintenance opening 41a.
[0028] In addition, fuse boxes 52, 53, 54, a cigarette lighter socket 55, etc. are provided at a position facing the maintenance opening 41a. As shown in Figs. 10 and 11, the tablet holder 40 is configured to be able to open and close the maintenance opening 41a, and in this embodiment, the maintenance opening 41a is opened by removing the tablet holder 40 from the panel cover 41. That is, by removing the tablet holder 40 from the panel cover 41, the water supply port 51, which is covered by the water supply cap 51a, is exposed to the outside of the traveling machine body 4 through the maintenance opening 41a. Then, an operator can replenish the radiator 50 with cooling water from the water supply port 51 by removing the water supply cap 51a.
[0029] 11, the groove portion 59 has a first groove 42d formed along the edge of the maintenance opening 41a, a second groove 42a communicating with the first groove 42d and extending rearward, a third groove 42b extending leftward from the rear end of the second groove 42a, and a fourth groove 42c communicating with the left end of the third groove 42b, passing between the combination switch 34 and the guide of the main shift lever 31, and extending to the side surface 41b of the panel cover 41.
[0030] When rain or other water gets on the periphery of the tablet holder 40, the first groove 42d is provided to prevent the water from passing through the first groove 42d and entering the maintenance opening 41a. The water that flows into the first groove 42d passes through the second groove 42a, the third groove 42b, and the fourth groove 42c, is guided to the side surface 41b of the panel cover 41, and is configured to fall down from the rice transplanter 1 along the side surface 41b. Such a flow of drainage is indicated by dashed arrows in Figures 10 and 11.
[0031] 10 to 12, a notch 56 is provided as an opening at the top of the flat surface 42 of the tablet holder 40. The notch 56 is an opening for routing a wiring 57 connectable to the tablet terminal 100 toward the maintenance opening 41a when the tablet holder 40 is attached to the panel cover 41. The wiring 57 is used, for example, to charge the tablet terminal 100. The notch 56 is covered from above by a canopy 56a provided on the panel cover 41, thereby preventing water from entering the notch 56.
[0032] As described above, in this embodiment, the display panel 20 is disposed in front of the steering wheel 7, and a maintenance opening 41a is provided between the display panel 20 and the operation panel 30, and the maintenance opening 41a is configured to be covered by the tablet holder 40.
[0033] Here, FIG. 2 is a plan view of the rice transplanter 1 as viewed from above, and FIG. 6(a) is a view of the display panel 20 as viewed from the viewpoint 60 of an operator seated in the driver's seat 8 as shown in FIG. 5. As shown in FIG. 2, in this embodiment, the display panel 20 is disposed in front of the steering wheel 7 so as not to overlap the steering wheel 7 in a plan view. Also, as shown in FIG. 5, the lower end 66 of the display panel 20 is located above the lower end 67 of the steering wheel 7. Therefore, as shown in FIG. 6(a), the steering wheel 7 and the display panel 20 do not overlap from the operator's viewpoint, and the visibility of the display panel 20 can be improved.
[0034] Furthermore, an operation panel 30 on which a starter switch 36 and the like are provided is disposed behind the display panel 20, but the display panel 20 has a larger inclination angle with respect to the horizontal plane than the operation panel 30. That is, as shown in FIG. 7, an angle θ1 between the display panel 20 and a horizontal plane 65 is larger than an angle θ2 between the operation panel 30 and the horizontal plane 65. This is because the display panel 20 is disposed forward so that the steering wheel 7 and the display panel 20 do not overlap from the viewpoint of the operator, and the inclination angle (angle θ1) of the display panel 20 is made larger so that the display panel 20 is easily visible to the operator. This can further improve the visibility of the display panel 20.
[0035] The space created between the display panel 20 and the operation panel 30 by providing the display panel 20 forward is utilized as a space for placing a tablet terminal and a space for maintenance. That is, a tablet holder 40 used for placing a tablet terminal is provided between the display panel 20 and the operation panel 30, and a flat surface 42 of the tablet holder 40 is also used as a lid for covering a maintenance opening 41a provided in a panel cover 41. The maintenance opening 41a is provided behind the display panel 20, in front of the operation panel 30, and below the steering wheel 7.
[0036] As shown in FIG. 2, the tablet holder 40 is disposed behind the display panel 20 and below the steering wheel 7 so that at least a part of the tablet holder 40 overlaps with the steering wheel 7 in a plan view. The tablet holder 40 has a flat portion 42, and protruding portions 43, 44, 45, 46 protruding upward from the flat portion 42 and positioning portions 47L, 47R, 48L, 48R. The tablet terminals placed on the placement portions 43a, 44a, 45a, 46a formed by the upper surfaces of the protruding portions 43, 44, 45, 46 are positioned by the positioning portions 47L, 47R, 48L, 48R, so that they will not fall even if the traveling machine body 4 shakes during planting work. In this way, the tablet terminals are held by the tablet holder 40, and planting work can be performed while viewing the information displayed on the tablet terminals, thereby improving usability. The tablet terminals held by the tablet holder 40 can be viewed from the space within the frame of the steering wheel 7 from the viewpoint of the worker.
[0037] Furthermore, since the maintenance opening 41a is connected to the engine room ER, the flat surface 42 covering the maintenance opening 41a may be heated by heat in the engine room ER. However, in this embodiment, the placement sections 43a, 44a, 45a, and 46a are configured by the upper surfaces of the convex sections 43, 44, 45, and 46 so that a gap is formed between the tablet terminal and the flat surface 42 when the tablet terminal is placed on the placement sections 43a, 44a, 45, and 46. This makes it difficult for heat to be transferred from the flat surface 42 to the tablet terminal, and also makes it possible to exhaust heat from the tablet terminal through the gap between the tablet terminal and the flat surface 42, thereby preventing the tablet terminal from generating excessive heat.
[0038] The maintenance opening 41a is used for replacing fuses in the fuse boxes 52, 53, 54 and for refilling the radiator 50 with cooling water from the water inlet 51, and the maintenance opening 41a can be easily accessed by removing the tablet holder 40 from the panel cover 41. This improves maintainability.
[0039] In particular, in this embodiment, as shown in Fig. 4, the rotation shaft 6a of the bonnet cover 6 covering the engine room ER is disposed below the display panel 20 and above the radiator 50. Therefore, even if the bonnet cover 6 is opened from the closed position to the open position around the rotation shaft 6a, the space between the bonnet cover 6 and the engine E and the radiator 50 cannot be made large, and there is a problem in maintainability when performing work such as replenishing cooling water to the radiator 50. However, in this embodiment, since the water supply port 51 is disposed to face the maintenance opening 41a, the cooling water can be easily replenished from the water supply port 51 by simply removing the tablet holder 40 from the panel cover 41 without opening or closing the bonnet cover 6, and maintainability can be improved.
[0040] Furthermore, maintenance of the electrical components provided below the operation panel 30 and inside the panel cover 41 can be performed through the maintenance opening 41a. Therefore, the electrical components of the operation panel 30 can be replaced and the harness can be attached and detached without removing the panel cover 41 or the cover body below the operation panel 30, improving maintainability.
[0041] Furthermore, the panel cover 41 is provided with a groove 59 that prevents water from entering the maintenance opening 41a, and the groove 59 can be used to drain water to the side surface 41b of the panel cover 41. Furthermore, the upper part of the tablet holder 40 is provided with a notch 56 for routing a wire 57 connectable to a tablet terminal toward the maintenance opening 41a. Therefore, for example, power can be taken from the cigarette lighter socket 55, and the tablet terminal held in the tablet holder 40 can be charged via the wire 57. <Other embodiments>
[0042] In the present embodiment, the tablet holder 40 has the flat portion 42, the convex portions 43, 44, 45, 46, and the positioning portions 47L, 47R, 48L, 48R, but is not limited thereto. In other words, the shape of the tablet holder 40 is not limited, and for example, at least one of the convex portions 43, 44, 45, 46 and the positioning portions 47L, 47R, 48L, 48R may be omitted.
[0043] In the present embodiment, the tablet holder 40 is detachably supported on the panel cover 41 by a knob bolt or the like, but this is not limiting. For example, the tablet holder 40 may be supported on the panel cover 41 so as to be openable and closable about a rotation axis, and the maintenance opening 41a may be exposed when the panel cover 41 is opened, and the maintenance opening 41a may be covered when the panel cover 41 is closed.
[0044] In the present embodiment, the maintenance opening 41a is covered by the tablet holder 40 that holds the tablet terminal, but the present invention is not limited to this. For example, the maintenance opening 41a may be covered by a cover member that is not configured to hold a tablet terminal. The cover member may be composed of a whiteboard, a small item holder, or the like. In addition, instead of the tablet holder 40, a smartphone holder capable of holding a smartphone may be applied. Furthermore, as shown in FIG. 12, mounting members 58L, 58R such as snap fits may be detachably provided on the positioning portions 47L, 47R of the tablet holder 40, respectively, and a whiteboard or a quick response may be attached to the tablet holder 40 by the mounting members 58L, 58R. The quick response is a manual that briefly describes the operation method of the rice transplanter 1. In addition, a tablet terminal may be placed on the placement portions 43a, 44a, 45a, 46a while a whiteboard or a quick response is attached to the tablet holder 40 by the mounting members 58L, 58R. In this case, the tablet terminal can be inserted into and removed from the placement sections 43a, 44a, 45a, and 46a from the front side with the whiteboard and quick response device attached to the tablet holder 40. Furthermore, the whiteboard, quick response device, and small items may be placed directly on the placement sections 43a, 44a, 45a, and 46a of the tablet holder 40.
[0045] In addition, in the present embodiment, the upper tank of the radiator 50 is directly supplied with cooling water from the water supply port 51, but the present invention is not limited to this. For example, the water supply port 51 may be provided in a reservoir tank provided beside the radiator 50, and the upper tank of the radiator 50 may be supplied with cooling water from the reservoir tank.
[0046] In the present embodiment, the groove 59 is configured to continue to the side surface 41b of the panel cover 41, but is not limited thereto. For example, the groove 59 may be configured to continue to the rear surface or the right side surface of the panel cover 41.
[0047] In the present embodiment, the bonnet cover 6 is configured to be rotatable about the rotation shaft 6a, but this is not limited thereto. For example, the bonnet cover 6 may be configured to be detachable from the traveling machine body 4.
[0048] In the present embodiment, the notch 56 for passing the wiring 57 is provided in the upper part of the flat surface portion 42 of the tablet holder 40, but the present invention is not limited to this. For example, instead of providing the notch 56 in the flat surface portion 42, a notch for passing the wiring 57 may be provided in the maintenance opening 41a. The notch is an area that is not covered by the flat surface portion 42 of the tablet holder 40. [Explanation of symbols]
