Description

[Technical Field]

[0001] The present invention relates to a work machine. [Background technology]

[0002] As shown in Patent Document 1, there is a work machine (rice transplanter) that is equipped with a machine body that performs work by autonomous driving, a ride-on driver's unit mounted on the machine body, and an information terminal mounted on the driver's unit that displays information. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-108606 Summary of the Invention [Problem to be solved by the invention]

[0004] The above-mentioned work machine may be operated in a manned, automatic driving mode with a driver in the driver's section, or in an unmanned, automatic driving mode without a driver in the driver's section. In both cases, there is a demand for a work machine that allows the display on an information terminal to be easily recognized.

[0005] The present invention provides a work machine in which the display on an information terminal is easy to read in both manned and unmanned automatic driving modes. [Means for solving the problem]

[0006] The working machine according to the present invention comprises: The vehicle is equipped with a machine that performs work travel by automatic driving, a ride-on driver's unit provided on the machine, and an information terminal provided on the driver's unit that displays information, and the information terminal is supported on a support member in a state in which its position can be changed around the machine's vertical axis between an inward position facing the inside of the driver's unit and an outward position facing outside the machine.

[0007] According to this configuration, by changing the orientation of the information terminal supported by the support member from an inward orientation, the display of the information terminal becomes easier to see from the driver's section, and by changing the orientation of the information terminal supported by the support member from an outward orientation, the display of the information terminal becomes easier to see from outside the aircraft. Because the display of the information terminal is easy to see from both the driver's section and outside the aircraft, the information displayed by the information terminal is easy to recognize in both manned and unmanned automatic driving.

[0008] In the present invention, The information terminal is preferably supported by the support member in a state in which the mounting angle thereof can be changed around a horizontal axis.

[0009] According to this configuration, the orientation of the information terminal can be changed up or down by changing the mounting angle of the information terminal relative to the support member. Even if the height or angle of the worker's line of sight is different, changing the orientation of the information terminal up or down makes the display of the information terminal easier to see, making it easier to recognize the information displayed by the information terminal.

[0010] In the present invention, The connecting member connecting the information terminal to the support member is provided with a first connecting member portion that is connected to the support member so as to be rotatable around the vertical axis of the body, allowing the orientation of the information terminal relative to the support member to be changed around the vertical axis of the body, and a second connecting member portion that is connected to the first connecting member portion so as to be able to change the mounting angle around the horizontal axis, allowing the mounting angle of the information terminal relative to the support member to be changed, and it is preferable that 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.

[0011] The angular range over which the information terminal swings about the aircraft's vertical axis to change its attitude between an inward and outward orientation is set wider than the angular range over which it swings about the horizontal axis to change the mounting angle, but because the information terminal swings with a swing radius of the first connecting member part that is shorter than the swing radius of the second connecting member part when changing its attitude between an inward and outward orientation, it is easy to avoid contact with components around the information terminal when changing its attitude.When changing the mounting angle, the information terminal swings with a swing radius of the first connecting member part that is longer than the swing radius of the first connecting member part, making it easy to fine-tune the mounting angle of the information terminal.

[0012] In the present invention, It is preferable that the support member is a support pole made of a pipe, and that the electric wires connected to the information terminal are routed so as to pass through the inside of the support pole.

[0013] According to this configuration, the electric wires are covered by the support posts, and therefore the support posts can be used as covers for the electric wires to protect the electric wires at low cost.

[0014] In the present invention, It is preferable that a swing restriction mechanism be provided for restricting the range of swing of the information terminal about the vertical axis of the machine body.

[0015] In devices where the electric wires are routed through the support pillar, when the information terminal is swung over a wide swing range around the vertical axis of the device, the electric wires may be significantly twisted and damaged. With this configuration, the swing restriction mechanism can restrict the swing range of the information terminal so that the information terminal can be swung only within a swing range that suppresses twisting of the electric wires. Since twisting of the electric wires can be suppressed even when the orientation of the information terminal is changed, damage to the electric wires can be prevented while utilizing the support pillar as a cover for the electric wires.

[0016] In the present invention, It is preferable that the vehicle is provided with a steering wheel for steering the vehicle and a speed change lever for changing the vehicle's traveling speed, and that the information terminal and the speed change lever are provided on either side of the steering wheel.

[0017] With this configuration, compared to when both the gear shift lever and the information terminal are provided on one of the two sides of the steering wheel, both the gear shift lever and the information terminal can be positioned at a shorter distance from the steering wheel. Because both the gear shift lever and the information terminal can be positioned at a relatively short distance from the steering wheel, it is easy to operate the gear shift lever and to see the information terminal while sitting in the driver's seat.

[0018] In the present invention, It is preferable that the device is provided with a remote control device that can remotely control the aircraft, and a connecting member that is connected to the information terminal and the support member and connects the information terminal to the support member, and that the connecting member is provided with a holder portion that can hold the remote control device.

[0019] According to this configuration, when the remote control is held in the holder, the remote control is supported by the connecting member via the holder, so that the remote control can be installed near the information terminal. For example, when the driver is in the driver's compartment, the remote control can be installed near the information terminal and operated without having to hold it in his / her hand, making it easier to operate the remote control.

[0020] In the present invention, It is preferable that the holder portion is configured to be able to hold the remote control device in a state in which the orientation of the operation surface of the remote control device and the orientation of the display surface of the information terminal are the same.

[0021] According to this configuration, for example, when the driver is in the driver's section, the remote control device is held in the holder section, so that the remote control device is held near the information terminal with the operating surface of the remote control device and the display surface of the information terminal facing in the same direction. This makes it easy to operate the remote control device, as it can be operated without holding it in one's hand and while looking at the display of the information terminal.

[0022] In the present invention, It is preferable that the connecting member is connected to the support member in a state in which it can swing about the vertical axis of the machine body, and that the information terminal is connected to the support member so that its position can be changed about the vertical axis of the machine body.

[0023] When the remote control is held in the holder, the remote control is supported by the connecting member via the holder, and even if the position of the information terminal is changed, the remote control swings around the information terminal, maintaining a constant position relative to the information terminal. Even if the position of the information terminal is changed, the positional relationship between the remote control and the information terminal does not change, making the remote control and the information terminal easy to operate and view.

[0025] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will now be described with reference to the accompanying drawings. In the following description, with regard to the body of a rice transplanter (an example of a "working machine"), the direction of arrow F shown in Figures 1 and 2 will be referred to as the "forward direction of the body," the direction of arrow B as the "rearward direction of the body," the direction of arrow U as the "upward direction of the body," the direction of arrow D as the "downward direction of the body," the direction towards the front of the page in Figure 1 and the direction of arrow L shown in Figure 2 as the "leftward direction of the body," and the direction towards the back of the page in Figure 1 and the direction of arrow R in Figure 2 as the "rightward direction of the body." The left-right direction of the body corresponds to the width direction of the body.

[0026] The rice transplanter shown in Figures 1 and 2 performs seedling planting work by manual and automatic driving. Automatic driving is possible in both manned automatic driving mode, where an operator is in the driver's section, and unmanned automatic driving mode, where the work vehicle is not in the driver's section.

[0027] [Overall view of rice transplanter] As shown in Figures 1 and 2, the rice transplanter includes a body 3 supported by a pair of steerable front wheels 1 (left and right) and a pair of steerable rear wheels 2 (left and right). A driving unit 6, including an engine 4 and an engine hood 5, is mounted at the front of the body 3. The output of the engine 4 is input to a continuously variable transmission 8 via a main clutch 7, and then transmitted from the continuously variable transmission 8 to the front wheels 1 and rear wheels 2. A driver's unit 9 is mounted at the rear of the body 3. The driver's unit 9 includes a steering wheel 10 for steering the front wheels 1, a driver's seat 11, a gearshift lever 12, and an information terminal 13. The gearshift lever 12 is pivoted to change the speed of the continuously variable transmission 8, thereby changing the drive speed of the front wheels 1 and rear wheels 2, thereby changing the traveling speed of the body 3. A seedling planting device 14, an example of a working device, is connected to the rear of the body 3. The seedling planting device 14 is connected to the body 3 via a link mechanism 15. The seedling planting device 14 is raised and lowered between a lowered working state and an elevated non-working state by the link mechanism 15 being swung up and down by the extension and contraction of a hydraulic cylinder 15a. On both sides of the drive unit 6, there are provided spare seedling storage devices 16 which can store spare seedlings to be supplied to the seedling planting device 14 by placing them on multiple upper and lower seedling shelves 16a.

[0028] [About autonomous driving] The machine body 3 is equipped with a positioning unit 17 that receives radio waves from satellites of the Global Navigation Satellite System to acquire position information for the machine body 3, and a control unit (not shown) connected to the positioning unit 17. The control unit includes an automatic driving microcomputer and the like. In this embodiment, the positioning unit 17 is provided in a front upper portion of the driving section 9. As shown in FIGS. 1 and 2, a support frame 18 for the positioning unit 17 is connected to the support columns 16b of the left and right spare seedling storage devices 16. The positioning unit 17 is held on the support columns 16b via the support frame 18. The control unit is connected to a travel operation device that operates the front wheels 1 and the continuously variable transmission 8, etc., and an operation operation device that operates the seedling planting device 14.

[0029] The rice transplanter is manually operated by the driver to travel along the perimeter of the field without performing any work. A field map is generated by this perimeter travel, and a travel route for work travel is set in advance. In the manned automatic travel mode and the unmanned automatic travel mode, the control unit controls the travel operation equipment based on the position information acquired by the positioning unit 17 and the preset travel route, and the machine body 3 automatically travels along the set travel route. In the unmanned automatic travel mode, automatic travel is started by operating the remote control device 40 (see Figure 8).

[0030] [Information terminal] As shown in Figures 1 and 2, an information terminal 13 is provided in the driver's section 9. In this embodiment, the information terminal 13 and the gearshift lever 12 are provided on both sides of the steering wheel 10. The information terminal 13 and the gearshift lever 12 are located closer to the steering wheel 10 than if both were provided on one side of 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 provided on the right side of the steering wheel 10 and the gearshift lever 12 is provided on the left side of the steering wheel 10, but it is also possible to provide the information terminal 13 on the left side of the steering wheel 10 and the gearshift lever 12 on the right side of the steering wheel 10.

[0031] The information terminal 13 is provided with a display surface 13a shown in Fig. 3, and information required for automatic planting of seedlings is displayed on the display surface 13a. In this embodiment, the display surface 13a is a touch panel. The information terminal 13 is provided with a graphic interface that displays information to the worker, such as map information of the work area, and allows the worker to input operations via the touch panel.

[0032] 1, the information terminal 13 is supported by a support member 20 located in the driver's section 9 along the vertical direction of the aircraft body. More specifically, as shown in FIGS. 4, 5, and 6, the information terminal 13 is supported by the support member 20 via a connecting member 21 that connects the information terminal 13 and the support member 20.

[0033] As shown in Figures 4, 5, and 6, the connecting member 21 has a first connecting member portion 22 on the support member side that is connected to the upper part of the support member 20, and a second connecting member portion 23 that is connected to the information terminal 13.

[0034] 5 and 6, the first connecting member portion 22 includes an upper plate portion 22a formed at the upper portion of the first connecting member portion 22, a lower plate portion 22b formed at the lower portion of the first connecting member portion 22, and a horizontal plate portion 22c formed at a horizontal end portion of the first connecting member portion 22. An upper connecting hole 22d is formed in the upper plate portion 22a. The inner diameter of the upper connecting hole 22d is set smaller than the outer diameter of the support member 20. A lower connecting hole 22e is formed in the lower plate portion 22b. The inner diameter of the lower connecting hole 22e is set larger than the outer diameter of the support member 20.

[0035] 4, 5, and 6, the first connecting member portion 22 is fitted onto the support member 20 from above via 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 received from below by the support member 20. The upper plate portion 22a is received by the support member 20, thereby positioning the first connecting member portion 22 in the up-down direction relative to the support member 20. The screw shank 24a of the first screw device 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 provided in the support member 20, whereby the first screw device 24 presses the upper plate portion 22a via the annular member 25, and the upper plate portion 22a is tightened and fixed to the support member 20 by the first screw device 24.

[0036] The second connecting member 23 is connected to the information terminal 13 by having one end side portion (not shown) connected to the information terminal 13 inside the rear cover 13b provided on the back of the information terminal 13. The second connecting member 23 is connected to the first connecting member 22 by having the other end side portion 23a extending out from the rear cover 13b and connected to the horizontal plate portion 22c of the first connecting member 22.

[0037] 4 and 6, 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 by engaging the other end side portion 23a with a fulcrum shaft 27 provided on the horizontal plate portion 22c and fastening the other end side portion 23a to the horizontal plate portion 22c with a second screw device 28. The threaded shank 28a of the second screw device 28 passes through the installation angle adjustment hole 23b, which is an elongated circular arc hole provided in the other end side portion 23a, and engages with a threaded hole member 29 provided in the horizontal plate portion 22c, whereby the other end side portion 23a is fastened and fixed to the horizontal plate portion 22c with the second screw device 28.

[0038] By loosening the first screw 24 and releasing the fastening of the first connecting member portion 22 to the support member 20, the connecting member 21 can be swung around the vertical axis P of the support member 20 as a swing fulcrum. By holding the first connecting member portion 22 or the information terminal 13 and swinging the connecting member 21 around the vertical axis P of the machine body, the information terminal 13 is swung around the vertical axis P of the machine body, and the orientation of the information terminal 13 supported by the support member 20 changes between an inward orientation facing the inside of the driver's unit 9 (see the solid line in FIG. 1 ) and an outward orientation facing outward from the machine body. The outward orientation can be selected from an outward orientation facing laterally outward from the machine body, an outward orientation facing forward outward from the machine body (see the two-dot chain line in FIG. 1 ), and an outward orientation diagonally outward between the outward orientation facing laterally outward from the machine body and the outward orientation facing forward outward from the machine body.

[0039] In the case of manned automatic driving, for example, by changing the orientation of information terminal 13 to an inward orientation, display surface 13a of information terminal 13 faces the inside of driving unit 9, making it easier for an operator positioned in driving unit 9 to see the display on information terminal 13. In the case of unmanned automatic driving, for example, by changing the orientation of information terminal 13 to an outward orientation, display surface 13a of information terminal 13 faces outward from the vehicle, making it easier for an operator positioned outside the vehicle to see the display on information terminal 13.

[0040] By loosening the second screw 28 and releasing the fastening of the second connecting member 23 to the first connecting member 22, the second connecting member 23 can be swung around the horizontal axis Y of the fulcrum shaft 27 as a swing fulcrum. Holding the information terminal 13 and swinging the second connecting member 23 around the horizontal axis Y of the fulcrum shaft 27 causes the information terminal 13 to swing around the horizontal axis Y relative to the support member 20, changing the mounting angle of the information terminal 13 around the horizontal axis Y relative to the support member 20. In other words, the vertical orientation of the information terminal 13 changes. The mounting angle of the information terminal 13 can be changed within an adjustment range set by the length of the mounting angle adjustment hole 23b. Changing the vertical orientation of the information terminal 13 makes the display on the information terminal 13 easier to see, even when the height or angle of the worker's line of sight is different.

[0041] [Swing restriction mechanism] In this embodiment, the support member 20 is a pipe support. As shown in Figures 5 and 6, the electric wires 33 connected to the information terminal 13 are routed so that they exit the information terminal 13 from the rear cover 13b of the information terminal 13 to the outside of the information terminal 13, pass through a wiring hole 20b provided in the support, enter the inside of the support, and then pass downward through the inside of the support toward the control unit. When the information terminal 13 is swung around the vertical axis P of the device, the electric wires 33 are twisted. The swing range of the information terminal 13 is restricted by a swing restriction mechanism 30 provided between the first connecting member part 22 and the support member 20, thereby preventing damage to the electric wires 33.

[0042] As shown in FIGS. 4, 6 and 7, the swing restriction mechanism 30 includes a stopper 31 provided on the support member 20 and a positioning pin 32 provided on the first connecting member part 22.

[0043] In the swing restriction mechanism 30, when the information terminal 13 swings toward the inside of the driver's unit 9, the positioning pin 32 hits the first acting portion 31a of the stopper 31, preventing further swing of the information terminal 13, and when the information terminal 13 swings toward the outside of the machine body, the positioning pin 32 hits the second acting portion 31b of the stopper 31, preventing further swing of the information terminal 13. The swing range of the information terminal 13 is set by the movement range of the positioning pin 32. In this embodiment, the swing range of the information terminal 13 is set to approximately 180 degrees.

[0044] 4, 5, and 6, the connecting member 21 that connects 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 device 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 device body. The second connecting member portion 23 is supported on the free end of the first connecting member portion 22 so as to be swingable about the horizontal axis Y, allowing the mounting angle of the information terminal 13 to the support member 20 to be changed about the horizontal axis Y.

[0045] The angular range over which the information terminal 13 can be swung about the aircraft's vertical axis P to change its attitude between an inward facing attitude and an outward facing attitude is set by the swing restriction mechanism 30, and the angular range over which the information terminal 13 can be swung about the horizontal axis Y to change the mounting angle is set by the mounting angle adjustment hole 23b. The angular range over which the information terminal 13 can be swung to change its attitude between an inward facing attitude and an outward facing attitude is set wider than the angular range over which the information terminal 13 can be swung to change the mounting angle.

[0046] 4 and 5, the swing radius L1 of the first connecting member part 22 about the vertical axis P of the aircraft, which is used to change the attitude of the information terminal 13 between an inward attitude and an outward attitude, is set to be shorter than the swing radius L2 of the second connecting member part 23 about the horizontal axis Y, which is used to change the mounting angle of the information terminal 13. When changing its attitude, the information terminal 13 swings with a swing radius L1 that is shorter than the swing radius L2, making it easy to avoid contact with components around the information terminal 13 when changing its attitude. When changing the mounting angle, the information terminal 13 swings with a swing radius L2 that is longer than the swing radius L1, making it easy to fine-tune the mounting angle of the information terminal 13.

[0047] [Remote control device] The rice transplanter is equipped with a remote control device 40 shown in Figure 8, and the rice transplanter can be remotely controlled using the remote control device 40. In the unmanned automatic traveling mode, automatic traveling is started by operating the remote control device 40.

[0048] As shown in FIG. 8, seven buttons and two indicators are provided on the operation surface 40a of the remote control device 40. The first button 41 is a power ON / OFF button. The second button 42, when pressed once, pauses the machine 3 while maintaining the automatic travel mode. Furthermore, when pressed simultaneously with the function button 48, the second button 42 stops the machine 3 and ends the automatic travel mode. The engine is not stopped at this time. The third button 43, when pressed once, accelerates the machine 3, and when pressed simultaneously with the function button 48, moves the machine 3 forward at a slow speed. The fourth button 44, when pressed once, decelerates the machine 3, and when pressed simultaneously with the function button 48, moves the machine 3 backward at a slow speed. The fifth button 45, when pressed simultaneously with the function button 48, starts automatic travel. The sixth button 46, when pressed simultaneously with the function button 48, starts planting work. The first indicator 49a indicates the remaining battery charge, and when the remaining battery charge becomes low, the display color changes from green to red. The second indicator 49b indicates whether communication is ON or OFF. In other words, the second indicator 49b indicates that the remote control device 40 has been operated. The second indicator 49b can also display that an operation by the remote control device 40 has been accepted by the control system of the rice transplanter.

[0049] 5 and 6, the connecting member 21 is provided with a holder portion 50 capable of holding the remote control device 40. In this embodiment, the holder portion 50 is provided on the first connecting member portion 22 of the connecting member 21. The holder portion 50 can also be provided on the second connecting member portion 23 of the connecting member 21. The holder portion 50 is provided on the first connecting member portion 22 by connecting the holder portion 50, which is manufactured separately from the first connecting member portion 22, to the first connecting member portion 22 with a connecting screw. By holding the remote control device 40 on the connecting member 21, the remote control device 40 can be operated without holding it in the hand.

[0050] 5 and 6, the holder section 50 has an operating tool storage space 55 formed by a bottom wall 51, a front wall 52, a rear wall 53, and left and right side walls 54. The remote control device 40 is held by the holder section 50 when it is inserted into the operating tool storage space 55 from above. The remote control device 40 can be removed from the holder section 50 by pulling it upward out of the operating tool storage space 55. A cutout section 56 is provided across the front wall 52 and the bottom wall 51. A cushioning material 57 is attached to the rear wall 53. The cushioning material 57 presses the remote control device 40 against the front wall 52 to prevent the remote control device 40 from rattling.

[0051] 3, the holder 50 is configured to hold the remote controller 40 with the operating surface 40a of the remote controller 40 facing the same direction as the display surface 13a of the information terminal 13. The remote controller 40 is held in the holder 50 in a state that makes it easy to operate while viewing information displayed on the information terminal 13, making it easy to operate the remote controller 40.

[0052] [Another embodiment] (1) In the above embodiment, an example is shown in which the information terminal 13 is provided on the right side of the steering wheel 10, but this is not limited to this, and it may also be provided on the left side of the steering wheel 10 or in front of the steering wheel 10.

[0053] (2) In the above embodiment, an example is shown in which the information terminal 13 and the shift lever 12 are provided on both sides of the steering wheel 10, but both the information terminal 13 and the shift lever 12 may be provided on either side of the steering wheel 10.

[0054] (3) In the above-described embodiment, a configuration was adopted in which the information terminal 13 was supported by the support member 20 in a swingable manner to enable the attitude of the information terminal 13 to be changed. However, instead of this, for example, it is possible to adopt a configuration in which the support member 20 is divided into a terminal side portion to which the information terminal 13 is connected and an aircraft side portion, and the terminal side portion is rotatably supported by the aircraft side portion, or a configuration in which the entire support member 20 is rotatably supported by the aircraft.

[0055] (4) In the above embodiment, an example was shown in which the information terminal 13 was supported so that the mounting angle could be changed, but the mounting angle may not be changeable.

[0056] (5) In the above embodiment, the support member 20 is a pipe support, but the support member 20 may be a round bar, a square bar, an angle bar, or other material other than a pipe support. Furthermore, even if the support member 20 is a pipe support, the electric wire 33 may be wired so as not to pass through the inside of the support.

[0057] (6) In the above embodiment, an example in which the swing restriction mechanism 30 is provided is shown, but the swing restriction mechanism 30 may not be provided.

[0058] (7) In the above-described embodiment, an example in which the holder unit 50 is provided is shown, but the holder unit 50 may not be provided. Furthermore, even if the holder unit 50 is provided, the remote control 40 may be held in a state in which the orientation of the operation surface 40a of the remote control 40 and the orientation of the display surface 13a of the information terminal 13 are different.

[0059] (8) In the above embodiment, the swing radius L1 of the first connecting member part 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 part 23 for changing the mounting angle of the information terminal 13. However, this is not limited to this. For example, the swing radius L1 may be set to be longer than the swing radius L2, or the swing radius L1 and the swing radius L2 may be set to be equal. [Industrial Applicability]

[0060] The present invention is not limited to rice transplanters, but can also be applied to various types of work machines such as tractors and pesticide sprayers. [Explanation of symbols]
