[0006] The above-mentioned work machines sometimes operate by manned autonomous driving with a driver aboard, and sometimes operate by unmanned autonomous driving without a driver aboard. A work machine is desired that allows easy reading of the information terminal display in either manned or unmanned autonomous driving mode. Summary of the Invention

[0007] The present invention provides a working machine that can easily identify the display of an information terminal in either manned or unmanned automatic driving.

[0008] The operating machine provided by the present invention has:

[0009] A machine body that performs work travel by automatic driving; a riding-type driving part that is equipped with the machine body; and an information terminal that is provided in the driving part and displays information, wherein the information terminal is supported on a supporting member in a state in which its posture can be changed around the vertical axis of the machine body between an inward posture and an outward posture, wherein the inward posture is a posture of the information terminal facing the inside of the driving part, and the outward posture is a posture of the information terminal facing the outside of the machine body.

[0010] According to this structure, by changing the position of the information terminal supported by the support member to face inward, the information terminal display is easily visible from the driver's seat. By changing the position of the information terminal supported by the support member to face outward, the information terminal display is easily visible from outside the vehicle. The information terminal display is easily visible from both the driver's seat and outside the vehicle, making it easy to read the information displayed on the information terminal in both manned and unmanned autonomous driving situations.

[0011] In the present invention, it is preferred that

[0012] The information terminal is supported by the support member in a state where the installation angle thereof can be changed around the horizontal axis.

[0013] According to this structure, the orientation of the information terminal can be changed vertically by changing the mounting angle of the information terminal relative to the support member. Even when the operator's line of sight is at different heights or angles, the information terminal display can be easily viewed by changing the orientation of the information terminal, making it easier to recognize the information displayed on the information terminal.

[0014] In the present invention, it is preferred that

[0015] The connecting member connecting the information terminal to the supporting member includes: a first connecting member portion, which is connected to the supporting member in a manner that can be rotated and adjusted around the vertical axis of the body, so that the information terminal can change its direction around the vertical axis of the body relative to the supporting member; and a second connecting member portion, which is connected to the first connecting member portion in a manner that can change the installation angle around the horizontal axis, so that the information terminal can change its installation angle relative to the supporting member, and the swing radius of the first connecting member portion around the vertical axis of the body is shorter than the swing radius of the second connecting member portion around the horizontal axis.

[0016] The angular range of the information terminal's swing about the vertical axis of the machine body to change between the inward and outward positions is set to be larger than the angular range of its swing about the horizontal axis to change the mounting angle. When changing between the inward and outward positions, the information terminal swings at a swing radius of the first connecting member portion that is shorter than the swing radius of the second connecting member portion. This makes it easier to prevent the information terminal from contacting surrounding components during the position change. When changing the mounting angle, the information terminal swings at a swing radius of the first connecting member portion that is longer than the swing radius of the first connecting member portion. This facilitates fine adjustment of the information terminal's mounting angle.

[0017] In the present invention, it is preferred that

[0018] The supporting member is a pipe support, and the electric wires connected to the information terminal are routed in a state of passing through the interior of the support.

[0019] According to this structure, since the electric wires are covered by the support, the support can be effectively used as a cover for the electric wires to protect the electric wires at low cost.

[0020] In the present invention, it is preferred that

[0021] The device is provided with a swing limiting mechanism for limiting the swing range of the information terminal around the vertical axis of the body.

[0022] When the information terminal is routed through the interior of the support, the wires may be significantly twisted and damaged when the terminal is swung about its vertical axis over a wide range. With this structure, the swing limiting mechanism limits the swing range of the terminal, limiting the swinging of the terminal to a range that suppresses twisting of the wires. Since twisting of the wires is suppressed even when the terminal changes direction, the support effectively serves as a cover for the wires while preventing damage to the wires.

[0023] In the present invention, it is preferred that

[0024] The vehicle comprises a steering wheel for steering the vehicle body and a shift lever for changing the travel speed of the vehicle body, wherein the information terminal and the shift lever are separately provided on both sides of the steering wheel.

[0025] According to this structure, compared with a case where both the shift lever and the information terminal are arranged on one of the two lateral sides of the steering wheel, the shift lever and the information terminal can be located closer to the steering wheel. Since both the shift lever and the information terminal can be located closer to the steering wheel, the shift lever can be easily operated and the information terminal can be easily viewed even when the driver is seated.

[0026] In the present invention, it is preferred that

[0027] The device comprises a remote control unit capable of remotely controlling the machine body, and a connecting member connected to the information terminal and the support member to connect the information terminal to the support member, wherein the connecting member comprises a bracket capable of holding the remote control unit.

[0028] With this structure, when the remote control is held in the bracket, it is supported by the connecting member via the bracket, allowing the remote control to be placed next to the information terminal. For example, when riding in the cab, the remote control can be placed next to the information terminal, making it easy to operate without having to hold it.

[0029] In the present invention, it is preferred that

[0030] The stand portion is configured to hold the remote controller in a state in which the operation surface of the remote controller is oriented in the same direction as the display surface of the information terminal.

[0031] According to this structure, for example, when riding in the driving part, by holding the remote operating part on the bracket part, the remote operating part will be held next to the information terminal with the operating surface of the remote operating part and the display surface of the information terminal facing the same direction. Therefore, there is no need to hold the remote operating part with hands, and the remote operating part can be operated while observing the display of the information terminal, so it is easy to operate the remote operating part.

[0032] In the present invention, it is preferred that

[0033] The connecting member is connected to the supporting member in a state of being swingable about the axis in the vertical direction of the body, and the information terminal is connected to the supporting member in a manner of being able to change its posture about the axis in the vertical direction of the body.

[0034] When the remote control is held in the bracket, it is supported by the connecting member via the bracket. Even if the information terminal changes its position, the remote control swings relative to the information terminal, maintaining a fixed position relative to the information terminal. Even if the information terminal changes its position, the positional relationship between the remote control and the information terminal remains unchanged, making operation and observation of the remote control and the information terminal easy.

DETAILED DESCRIPTION

[0045] Hereinafter, an embodiment as an example of the present invention will be described with reference to the drawings.

[0046] It should be noted that, in the following description, the body of the rice transplanter (an example of a "working machine") will be Figure 1 、 Figure 2 The direction of the arrow F shown is set as the "front direction of the body", the direction of the arrow B is set as the "backward direction of the body", the direction of the arrow U is set as the "upward direction of the body", the direction of the arrow D is set as the "downward direction of the body", and Figure 1 The direction of the paper surface side and Figure 2 The direction of the arrow L shown is set as "the left direction of the machine body". Figure 1 The direction of the back side of the paper and Figure 2 The direction of the arrow R is defined as the "right direction of the machine body." The left-right direction of the machine body corresponds to the lateral width direction of the machine body.

[0047] Figure 1 、 Figure 2 The rice transplanter shown here can perform rice seedling transplanting work by manual driving and automatic driving. The automatic driving can be performed in two modes: a manned automatic driving mode with an operator on board the driving part and an unmanned automatic driving mode without an operator on board the driving part.

[0048] 〔Overall structure of rice transplanter〕

[0049] like Figure 1 、 Figure 2As shown, the rice transplanter includes a machine body 3 supported by a pair of left and right driven and steerable front wheels 1 and a pair of left and right driven rear wheels 2. A power unit 6 is provided at the front of the machine body 3. The power unit 6 includes an engine 4, an engine hood 5, and other components. The output of the engine 4 is input to a continuously variable transmission 8 via a main clutch 7, from which it is transmitted to the front and rear wheels 1 and 2. A ride-on cab 9 is provided at the rear of the machine body 3. The cab 9 includes a steering wheel 10 for steering the front wheels 1, a driver's seat 11, a shift lever 12, and an information terminal 13. The shift lever 12 is swung to shift the continuously variable transmission 8, thereby changing the drive speed of the front and rear wheels 1 and 2, thereby changing the travel speed of the machine body 3. A rice seedling planting device 14, an example of a working device, is connected to the rear of the machine body 3. The rice seedling planting device 14 is connected to the machine body 3 via a linkage mechanism 15. The link mechanism 15 swings up and down by extending and retracting the hydraulic cylinder 15a, thereby raising and lowering the seedling planting device 14 between a lowered operating state and an elevated non-operating state. A reserve seedling storage device 16 is provided on both lateral sides of the driving portion 6. This reserve seedling storage device 16 stores reserve seedlings to be supplied to the seedling planting device 14 on multiple layers of seedling racks 16a.

[0050] [About autonomous driving]

[0051] A positioning unit 17 that receives radio waves from a satellite of the global navigation satellite system to obtain the position information of the body 3 and a control unit (not shown) connected to the positioning unit 17 are mounted on the body 3. The control unit includes a microcomputer for automatic driving, etc. In this embodiment, the positioning unit 17 is provided in the upper front part of the driving part 9. Figure 1 、 Figure 2 As shown, the support frame 18 of the positioning unit 17 is connected to the left and right support posts 16b of the seedling storage device 16. The positioning unit 17 is held by the support frame 18 on the support posts 16b. The control unit is connected to the driving control device that operates the front wheels 1, the continuously variable transmission 8, etc., and the operation control device that operates the seedling planting device 14.

[0052] Along the periphery of the farmland, the driver manually operates the rice transplanter to drive without performing any work. A farmland map is generated by driving around the periphery. The driving path for the work is preset. In the manned automatic driving mode and the unmanned automatic driving mode, the control unit controls the driving operation device based on the position information obtained by the positioning unit 17 and the preset driving path, and the machine body 3 automatically drives along the set driving path. In the unmanned automatic driving, the remote control unit 40 (see Figure 8 ) to start automatic driving.

[0053] 〔Information Terminal〕

[0054] like Figure 1 、 Figure 2 As shown, the driving unit 9 is provided with an information terminal 13. In this embodiment, the information terminal 13 and the shift lever 12 are located on either side of the steering wheel 10. Compared to placing both on one side of the steering wheel 10, the information terminal 13 and the shift lever 12 are located closer to the steering wheel 10, making them easier to see and operate from the driver's seat 11. In this embodiment, the information terminal 13 is located on the right side of the steering wheel 10, and the shift lever 12 is located on the left side of the steering wheel 10. However, the information terminal 13 may be located on the left side of the steering wheel 10, and the shift lever 12 may be located on the right side of the steering wheel 10.

[0055] The information terminal 13 has Figure 3 The display surface 13a shown displays information required for the automated rice seedling transplanting operation. In this embodiment, the display surface 13a is a touch panel. The information terminal 13 includes a graphical interface that displays information such as map information of the work site to the operator and allows the operator to input operations via the touch panel.

[0056] like Figure 1 As shown in FIG. 1 , the information terminal 13 is supported by a support member 20 located on the driving portion 9 along the vertical direction of the machine body. Figure 4 、 Figure 5 、 Figure 6 As shown, the information terminal 13 is supported by the support member 20 via a connecting member 21 connecting the information terminal 13 and the support member 20 .

[0057] like Figure 4 、 Figure 5 、 Figure 6 As shown, the connecting member 21 includes a first connecting member portion 22 connected to the upper portion of the supporting member 20 on the supporting member side and a second connecting member portion 23 connected to the information terminal 13 .

[0058] like Figure 5 、 Figure 6 As shown, the first connecting member portion 22 includes an upper plate portion 22a formed at the top of the first connecting member portion 22, a lower plate portion 22b formed at the bottom of the first connecting member portion 22, and a transverse plate portion 22c formed at the lateral end of the first connecting member portion 22. The upper plate portion 22a is provided with an upper connecting hole 22d. The inner diameter of the upper connecting hole 22d is set to be smaller than the outer diameter of the support member 20. The lower plate portion 22b is provided with a lower connecting hole 22e. The inner diameter of the lower connecting hole 22e is set to be larger than the outer diameter of the support member 20.

[0059] like Figure 4 、 Figure 5 、 Figure 6As shown, the first connecting member 22 is externally fitted to the support member 20 from above through the lower connecting hole 22e. The upper plate portion 22a abuts against the upper end portion 20a of the support member 20 around the upper connecting hole 22d and is supported by the support member 20 from below. The upper plate portion 22a is supported by the support member 20, thereby positioning the first connecting member 22 in the vertical direction relative to the support member 20. The threaded shaft portion 24a of the first screw member 24 passes through the through-hole of the annular member 25 and the upper connecting hole 22d and engages with the threaded hole member 26 of the support member 20. As a result, the first screw member 24 presses the upper plate portion 22a through the annular member 25, and the upper plate portion 22a is fastened to the support member 20 by the first screw member 24.

[0060] One end side portion (not shown) of the second connecting member portion 23 is connected to the information terminal 13 inside the rear cover 13b provided on the back of the information terminal 13, thereby connecting the second connecting member portion 23 to the information terminal 13. The other end side portion 23a of the second connecting member portion 23 extends from the rear cover 13b and is connected to the horizontal plate portion 22c of the first connecting member portion 22, thereby connecting the second connecting member portion 23 to the first connecting member portion 22.

[0061] like Figure 4 、 Figure 6 As shown, the other end side portion 23a of the second connecting member portion 23 is connected to the horizontal plate portion 22c of the first connecting member portion 22 in the following manner: the other end side portion 23a is engaged with a fulcrum shaft 27 provided on the horizontal plate portion 22c, and the other end side portion 23a of the second connecting member portion 23 is fastened to the horizontal plate portion 22c by a second screw member 28. The threaded shaft portion 28a of the second screw member 28 passes through the mounting angle adjustment hole 23b of the arc-shaped elongated hole provided in the other end side portion 23a and engages with a threaded hole member 29 provided on the horizontal plate portion 22c, thereby fastening the other end side portion 23a to the horizontal plate portion 22c by the second screw member 28.

[0062] The first screw 24 is operated toward the loosening side to release the fastening of the first connecting member 22 to the supporting member 20, thereby allowing the connecting member 21 to swing with the vertical axis P of the supporting member 20 as the swing fulcrum. The first connecting member 22 or the handheld information terminal 13 is held by the hand and the connecting member 21 is swung around the vertical axis P of the body. As a result, the information terminal 13 is swung around the vertical axis P of the body. The posture of the information terminal 13 supported by the supporting member 20 is in the inward posture facing the inside of the driving part 9 (refer to FIG. Figure 1 The posture changes between the outward posture toward the outside of the body and the outward posture toward the outside of the body. As the outward posture, the outward posture toward the outside of the body, the outward posture toward the front of the body (see Figure 1) and an outward posture that is obliquely outward between the outward posture toward the lateral outside of the body and the outward posture toward the front outside of the body.

[0063] In the case of manned autonomous driving, the information terminal 13 is positioned inwardly, with the display surface 13a of the information terminal 13 facing the interior of the cab 9, making it easier for the operator in the cab 9 to see the display on the information terminal 13. In the case of unmanned autonomous driving, the information terminal 13 is positioned outwardly, with the display surface 13a of the information terminal 13 facing the exterior of the vehicle, making it easier for the operator outside the vehicle to see the display on the information terminal 13.

[0064] The second screw member 28 is operated toward the loosening side to release the fastening of the second connecting member portion 23 to the first connecting member portion 22, thereby allowing the second connecting member portion 23 to swing with the horizontal axis Y of the fulcrum shaft 27 as the swing fulcrum. The handheld information terminal 13 swings the second connecting member portion 23 around the horizontal axis Y of the fulcrum shaft 27, thereby swinging the information terminal 13 around the horizontal axis Y relative to the support member 20, and the installation angle of the information terminal 13 around the horizontal axis Y relative to the support member 20 changes. In other words, the vertical direction of the information terminal 13 changes. The change in the installation angle of the information terminal 13 can be performed within the adjustment range set according to the length of the installation angle adjustment hole 23b. Even if the height and angle of the operator's line of sight are different, it is easy to observe the display of the information terminal 13 by changing the vertical direction of the information terminal 13.

[0065] [Swing limiting mechanism]

[0066] In this embodiment, the support member 20 is a pipe support. Figure 5 、 Figure 6 As shown, the wires 33 connected to the information terminal 13 are routed as follows: they extend from the rear cover 13b of the information terminal 13 toward the outside of the information terminal 13, pass through a wiring hole 20b provided in the support column, and then pass downward through the interior of the support column to the control unit. When the information terminal 13 swings about the vertical axis P of the machine body, the wires 33 twist. The swing range of the information terminal 13 is limited by a swing limiting mechanism 30, which is arranged to span the first connecting member 22 and the support member 20, to prevent damage to the wires 33.

[0067] like Figure 4 、 Figure 6 、 Figure 7 As shown, the swing restriction mechanism 30 includes a stopper 31 provided on the support member 20 and a positioning pin 32 provided on the first coupling member portion 22 .

[0068] In the swing restriction mechanism 30, when the information terminal 13 swings toward the interior of the cab 9, the positioning pin 32 abuts the first operating portion 31a of the stopper 31, preventing further swinging of the information terminal 13. When the information terminal 13 swings toward the exterior of the vehicle body, the positioning pin 32 abuts the second operating portion 31b of the stopper 31, preventing further swinging of the information terminal 13. The swing range of the information terminal 13 is determined by the range of movement of the positioning pin 32. In this embodiment, the swing range of the information terminal 13 is set to approximately 180 degrees.

[0069] like Figure 4 、 Figure 5 、 Figure 6 As shown, the connecting member 21 connecting the information terminal 13 to the support member 20 includes a first connecting member portion 22 and a second connecting member portion 23. The first connecting member portion 22 is supported on the support member 20 so as to be rotatable about the vertical axis P of the machine body, allowing the information terminal 13 to change its position between an inward position and an outward position about the vertical axis P of the machine body. The second connecting member portion 23 is supported at the free end of the first connecting member portion 22 so as to be swingable about the horizontal axis Y, allowing the information terminal 13 to change its installation angle relative to the support member 20 about the horizontal axis Y.

[0070] The angular range within which the information terminal 13 can swing about the vertical axis P of the machine body to change between the inward and outward positions is set by the swing limiting mechanism 30, while the angular range within which the information terminal 13 can swing about the horizontal axis Y to change the mounting angle is set by the mounting angle adjustment hole 23b. The angular range within which the information terminal 13 can swing to change between the inward and outward positions is set to be larger than the angular range within which the information terminal 13 can swing to change the mounting angle.

[0071] like Figure 4 、 Figure 5 As shown, the first connecting member 22, which allows the information terminal 13 to change its position between an inward and outward position, has a swing radius L1 about the vertical axis P of the machine body that is shorter than the swing radius L2 about the horizontal axis Y of the second connecting member 23, which allows the information terminal 13 to change its installation angle. When changing its position, the information terminal 13 swings at a swing radius L1 that is shorter than the swing radius L2, thereby easily preventing the information terminal 13 from contacting surrounding components during the position change. When changing its installation angle, the information terminal 13 swings at a swing radius L2 that is longer than the swing radius L1, thereby facilitating fine adjustment of the installation angle of the information terminal 13.

[0072] Remote control unit

[0073] Rice transplanter with Figure 8The remote control member 40 shown can be used to remotely control the rice transplanter. In the unmanned automatic driving mode, the remote control member 40 is operated to start the automatic driving.

[0074] like Figure 8 As shown, the operating surface 40a of the remote control 40 is equipped with seven buttons and two indicators. The first button 41 is the power on / off button. The second button 42, when pressed single-handedly, temporarily stops the machine 3 while maintaining the automatic driving mode. Furthermore, pressing the second button 42 simultaneously with the function button 48 stops the machine 3, ending the automatic driving mode. The engine is not stopped at this time. The third button 43 accelerates the machine 3 with a single press, and moves the machine 3 forward at a slight speed when pressed simultaneously with the function button 48. The fourth button 44 decelerates the machine 3 with a single press, and moves the machine 3 backward at a slight speed when pressed simultaneously with the function button 48. The fifth button 45 starts automatic driving by pressing simultaneously with the function button 48. The sixth button 46 starts planting by pressing simultaneously with the function button 48. The first indicator 49a indicates the remaining battery level; as the battery level decreases, the display color changes from green to red. The second indicator 49b indicates whether communication is on or off. That is, the second indicator 49b indicates that the remote operating element 40 has been operated. In addition, the second indicator 49b may also be configured to display information indicating that the operation by the remote operating element 40 has been accepted by the control system of the rice transplanter.

[0075] like Figure 5 、 Figure 6 As shown, the connecting member 21 includes a bracket portion 50 capable of holding the remote control unit 40. In this embodiment, the bracket portion 50 is attached to the first connecting member portion 22 of the connecting member 21. The bracket portion 50 may also be attached to the second connecting member portion 23 of the connecting member 21. Attaching the bracket portion 50 to the first connecting member portion 22 is accomplished by attaching the bracket portion 50, which is manufactured separately from the first connecting member portion 22, to the first connecting member portion 22 using fastening screws. By holding the remote control unit 40 on the connecting member 21, the remote control unit 40 can be operated without having to hold it manually.

[0076] In detail, Figure 5 、 Figure 6As shown, the bracket portion 50 includes an operating element accommodating space 55 formed by a bottom wall 51, a front wall 52, an inner wall 53, and left and right transverse walls 54. The remote operating element 40 is held by the bracket portion 50 by inserting it from above into the operating element accommodating space 55. The remote operating element 40 can be removed from the bracket portion 50 by pulling it upward from the operating element accommodating space 55. A notch 56 is provided across the front wall 52 and bottom wall 51. A buffer 57 is attached to the inner wall 53. The buffer 57 presses the remote operating element 40 against the front wall 52 to prevent it from loosening.

[0077] like Figure 3 As shown, the bracket portion 50 is configured to hold the remote operating element 40 in a state where the operating surface 40a of the remote operating element 40 is oriented in the same direction as the display surface 13a of the information terminal 13. The remote operating element 40 is held on the bracket portion 50 in a state that allows easy operation of the remote operating element 40 while viewing information displayed on the information terminal 13. Therefore, the remote operating element 40 is easy to operate.

[0078] [Other Implementation Methods]

However, the present invention is not limited thereto and the information terminal 13 may be provided on the left side of the steering wheel 10 or in front of the steering wheel 10 .

[0080] (2) In the above embodiment, the information terminal 13 and the shift lever 12 are provided on both lateral sides of the steering wheel 10 . However, both the information terminal 13 and the shift lever 12 may be provided on either lateral side of the steering wheel 10 .

[0081] (3) In the above-mentioned embodiment, in order to enable the posture of the information terminal 13 to be changed, a structure is adopted in which the information terminal 13 is supported on the supporting member 20 in a swingable manner. However, instead of the above-mentioned structure, a structure may be adopted in which, for example, the supporting member 20 is divided into a terminal side portion for connecting the information terminal 13 and a body side portion, and the terminal side portion is supported on the body side portion in a rotatable manner, or a structure in which the supporting member 20 as a whole is supported on the body in a rotatable manner.

[0082] (4) In the above embodiment, an example is shown in which the information terminal 13 is supported so that the installation angle can be changed. However, the information terminal 13 may not be supported so that the installation angle can be changed.

[0083] (5) In the above embodiment, the supporting member 20 is an example of a pipe support. However, the supporting member 20 may be a non-pipe support such as a round bar, a square bar, or an angled member. Furthermore, even if the supporting member 20 is a pipe support, wiring may be employed so that the electric wire 33 does not pass through the interior of the support.

Furthermore, even if the bracket portion 50 is provided, a configuration may be employed in which the remote operating element 40 is held in a state in which the operating surface 40a of the remote operating element 40 is oriented in a direction different from the display surface 13a of the information terminal 13.

[0086] (8) In the above-described embodiment, the swing radius L1 of the first connecting member 22 for changing the position of the information terminal 13 between the inward position and the outward position is set to be shorter than the swing radius L2 of the second connecting member 23 for changing the mounting angle of the information terminal 13. However, the present invention is not limited to this.
