Summary of the Invention

Problems to be Solved by the Invention

[0004] In the rice transplanter described in Patent Document 1, the display unit is arranged in front of the steering wheel (on the side opposite to the driver's seat). In this configuration, the steering wheel exists in the line-of-sight direction when an operator sitting on the driver's seat views the display unit. Therefore, there is a concern that the visibility of the display unit is hindered by the steering wheel, and the visibility of the display unit may decrease. In addition, the body shapes (for example, height, seat height, etc.) of the operators sitting on the driver's seat vary. Therefore, if the installation angles of the display unit and the operation unit are fixed, there is a possibility that it may be difficult for some operators to view the display unit and operate the operation unit.

[0005] The present invention has been made to solve the above problems, and an object thereof is to provide a work vehicle that can improve the visibility when an operator sits on the driver's seat and views the display unit, and can realize the postures of the display unit and the operation unit suitable for the operator.

Means for Solving the Problems

[Modes for carrying out the invention]

[0009] Embodiments of the present invention will be described with reference to the drawings. For the convenience of the following explanation, unless otherwise specified, directions will be defined as follows. First, the direction of travel of the traveling body 2 of the rice transplanter 1 (left direction in Figure 1) will be referred to as the front (forward), and the opposite direction will be referred to as the rear (rear). Also, the left side of the traveling body 2 in the direction of travel will be referred to as the left (leftward), and the right side in the direction of travel will be referred to as the right (rightward). Furthermore, the direction of gravity will be referred to as the up and down direction, with the upstream side as the up (upward) and the downstream side as the down (downward). In the drawings, the front will be indicated by the symbol "F", the rear by "B", the left by "L", the right by "R", the up by "U", and the down by "D" as needed. Note that the upstream side refers to the starting point side when the direction is indicated by an arrow, and is synonymous with the upstream side. Also, the downstream side refers to the ending point side when the direction is indicated by an arrow, and is synonymous with the downstream side.

[0010] Furthermore, the display unit 28 and the operation unit 29, which will be described later, will be explained using the up, down, left, and right directions when the display unit 28 is viewed from a direction perpendicular to the display screen, and the operation unit 29 will also be explained using the up, down, left, and right directions when the operation unit 29 is viewed from the direction in which the buttons are pressed.

[0011] <1. Overview of the rice transplanter> FIG. 1 is a side view showing a schematic configuration of a rice transplanter 1 which is an example of a work vehicle according to an embodiment of the present invention. The rice transplanter 1 includes a traveling body 2 and a planting unit 3.

[0012] The traveling body 2 is supported by left and right front wheels 1a and left and right rear wheels 1b. An engine 1c as a drive source is mounted on the traveling body 2. The power output from the engine 1c is transmitted to a driven part via a transmission part 1d. The driven part includes the front wheels 1a and the rear wheels 1b, and also includes the planting unit 3. Therefore, the above-described transmission part 1d includes a PTO (Power Take Off) shaft for driving the planting unit 3.

[0013] The traveling body 2 includes a driver's seat 21 and an operation column 22. The driver's seat 21 is provided near the center in the front-rear direction on the traveling body 2. The driver's seat 21 is supported on the floor 2f of the traveling body 2 via a support base 20. An accelerator pedal (shift pedal), a brake pedal, etc. are also arranged on the floor 2f.

[0014] The operation column 22 is arranged in front of the driver's seat 21, and members operated by an operator (driver, operator) seated on the driver's seat 21 are arranged thereon. For example, a steering wheel 22a for an operator to operate the direction in which the rice transplanter 1 travels is arranged on the operation column 22. That is, the rice transplanter 1 includes a steering wheel 22a arranged in front of the driver's seat 21. In addition to the steering wheel 22a, various levers and switches (buttons) are arranged on the operation column 22, which will be described later. The operation column 22 is provided at the upper rear of a bonnet 23 arranged on the front side of the traveling body 2. The above-described engine 1c is arranged below the inside of the bonnet 23.

[0015] In the mobile unit 2, spare seedling trays 24 for holding spare seedling mats are provided on both the left and right sides of the bonnet 23. In this embodiment, four spare seedling trays 24 are provided on each side of the bonnet 23, spaced apart in the vertical direction. The number of spare seedling trays 24 can be changed as appropriate.

[0016] Two vertically extending support columns 25 are provided on each of the left and right sides of the bonnet 23. On both the left and right sides of the bonnet 23, the support columns 25 are spaced apart in the front-to-back direction. Each spare seedling tray 24 located on the right side of the bonnet 23 is rotatably attached to the two support columns 25 located on the right side of the bonnet 23 via mounting members 24a (see Figure 2). Similarly, each spare seedling tray 24 located on the left side of the bonnet 23 is rotatably attached to the two support columns 25 located on the left side of the bonnet 23 via mounting members 24a. Each spare seedling tray 24 on the right side of the bonnet 23 can be folded towards the bonnet 23 by rotating its right end upwards. Similarly, each spare seedling tray 24 on the left side of the bonnet 23 can be folded towards the bonnet 23 by rotating its left end upwards.

[0017] A positioning unit 27 is positioned at the top of each support column 25 via a support frame 26. The positioning unit 27 is provided to acquire the vehicle's position information by receiving radio signals transmitted from positioning satellites, as well as to communicate wirelessly with an external remote monitoring device.

[0018] A display unit 28 and an operating unit 29 are located on the right side of the hood 23, more specifically, to the right of the steering wheel 22a. Details of the display unit 28 and the operating unit 29 will be described later.

[0019] The planting unit 3 is connected to the rear of the traveling machine 2 via a lifting mechanism 4 so as to be able to move up and down. The lifting mechanism 4 includes a top link 41, a lower link 42, and a lifting cylinder 43. The top link 41 and the lower link 42 connect the traveling machine 2 and the planting unit 3. The lifting cylinder 43 is connected to the lower link 42. For example, by operating the planting lifting lever 233 (see Figure 2) on the operating column 22, the lifting cylinder 43 is extended and retracted, causing the lower link 42 to rotate and the top link 41 to rotate. This allows the planting unit 3 to be raised and lowered relative to the traveling machine 2.

[0020] The planting unit 3 includes a seedling loading device 31 on which a seedling mat is placed, and a seedling planting mechanism 32. The seedling planting mechanism 32 picks up one seedling from the seedling mat placed on the seedling loading device 31 and plants the picked-up seedling in the field (soil). The planting unit 3 is further provided with a rotor 33 and markers 34 that can be extended to the left and right. The rotor 33 is provided to level the rough field surface (e.g., headland) after turning. The left and right markers 34 are provided to form a trajectory on the field surface that will serve as a reference for travel in the next stroke. The planting unit 3 is further provided with a float for detecting the condition (hardness) of the field surface, and a rake for detecting the height of the field surface, etc.

[0021] In the traveling machine 2, a fertilizer application device 5 is provided between the driver's seat 21 and the planting unit 3. The fertilizer application device 5, driven by a fertilizer application motor, dispenses a predetermined amount of fertilizer stored in a hopper and supplies it to the field.

[0022] <2. Regarding switches, etc. on the control column> In this embodiment, some of the various switches operated by the worker seated in the driver's seat 21 during work are arranged as an operating unit 29 to the right of the steering wheel 22a, while the remaining switches and levers are arranged in the operating column 22. Below, in order to clearly distinguish them from the switches arranged in the operating unit 29, the switches and levers arranged in the operating column 22 will be briefly described.

[0023] Figure 2 is a perspective view of the operating column 22 from a diagonal rearward angle. In addition to the steering handle 22a described above, the operating column 22 also houses the main gear shift lever 221. The main gear shift lever 221 is located behind (towards the front of) the steering handle 22a and extends to the left. The main gear shift lever 221 is used to switch the direction of travel of the rice transplanter 1 (forward / neutral / reverse).

[0024] On the operation column 22, diagonally below the main gear lever 221 (towards the driver's seat 21), from left to right, are arranged the following components in order: seedling splicing switch 222, planting row stopper switch 223, key switch 224, sensitivity adjustment dial 225, speed setting dial 226, speed lock switch 227, and buzzer stop button 228.

[0025] The seedling transfer switch 222 is pressed when replenishing seedling mats from the spare seedling tray 24 to the seedling tray of the seedling loading device 31 in the planting unit 3. Pressing the seedling transfer switch 222 disables the operation of the accelerator pedal and cuts off the power transmission from the engine 1c to the planting unit 3. Furthermore, the rotation speed of the engine 1c is reduced.

[0026] The planting row stop switch 223 is a switch for stopping the planting of seedlings in a predetermined row, that is, stopping the operation of the planting claws of the seedling planting mechanism 32 and the seedling feeding belt of the seedling loading device 31. In this embodiment, four planting row stop switches 223 are provided in a row. For example, in a configuration for planting eight rows of seedlings, pressing the leftmost planting row stop switch 223 stops the planting of rows 1 and 2. Pressing the second planting row stop switch 223 from the left stops the planting of rows 3 and 4. Pressing the third planting row stop switch 223 from the left stops the planting of rows 5 and 6. Pressing the fourth planting row stop switch 223 from the left (the rightmost) stops the planting of rows 7 and 8.

[0027] A key for starting or stopping engine 1c is inserted into the key switch 224. The sensitivity adjustment dial 225 is operated to adjust the sensitivity of the hydraulic control (lifting / lowering control) according to the hardness (softness) of the field surface. For example, in a soft field, turning the dial to increase the sensitivity (make it more sensitive) adjusts the float to float slightly higher. Conversely, in a hard field, turning the dial to decrease the sensitivity (make it less sensitive) adjusts the float to sink slightly lower.

[0028] The speed setting dial 226 is used to set the maximum speed when the accelerator pedal is pressed. The speed lock switch 227 is used to lock the vehicle speed at a desired speed. The buzzer stop button 228 is used to stop the warning sound.

[0029] In the operating column 22, a combination switch 229 is located to the right of the steering wheel 22a and diagonally in front of the sensitivity adjustment dial 225. The combination switch 229 includes switches for turning the left and right turn signals on and off, switches for turning the work lights on and off, and a switch for sounding the horn.

[0030] In the operation column 22, to the right of the combination switch 229 and diagonally in front of the speed setting dial 226, is the edge-shift button 230. The edge-shift button 230 is used to move the seedling tray of the planting unit 3 to the edge. Further diagonally in front of the edge-shift button 230 is the hydraulic changeover switch 231. The hydraulic changeover switch 231 is used to turn the hydraulic control (lifting and lowering control) of the planting unit 3 on and off. To the right of the hydraulic changeover switch 231 is the robot button 232. The robot button 232 is used to enable robot operation (fully automated, unmanned operation) when the rice transplanter 1 has a robot operation function, and is provided as needed.

[0031] In the operation column 22, the planting lifting lever 233 is positioned diagonally in front of the buzzer stop button 228. The planting lifting lever 233 is used to raise and lower the planting unit 3, turn the planting (clutch) on and off, and operate the marker 34.

[0032] The switches and levers described above, located on the operating column 22, are positioned around the steering handle 22a, taking into consideration the ease of use for the operator. Note that the arrangement of the switches and levers shown in Figure 2 is just one example and is not limited to this arrangement.

[0033] In addition, a cover portion 234 is positioned diagonally in front of the steering handle 22a in the operating column 22. A handle portion 234a extending vertically is provided on the upper surface of the cover portion 234. For example, three handle portions 234a are provided and are spaced apart in the left-right direction. Note that the number of handle portions 234a is not limited to the three mentioned above and can be set arbitrarily.

[0034] The lid 234 is detachably positioned to cover the upper opening of a small item storage compartment (not shown) located inside the operating column 22. By grasping the handle 234a and removing the lid 234, the operator can insert and remove small items (e.g., cutters, scissors, etc.) into the small item storage compartment. Furthermore, when the lid 234 is attached to the small item storage compartment, the operator's portable terminal can be placed between adjacent handles 234a.

[0035] Furthermore, a connection connector for connecting to a portable memory may be provided inside the small parts storage compartment described above. Then, a data file (for example, a fertilization map) stored in the portable memory may be read via the connection connector and stored in the storage unit 100 (see Figure 9) of the rice transplanter 1.

[0036] In the operation column 22, cup holders 235 are provided on both the left and right sides of the lid 234. The cup holders 235 accommodate and support beverage containers such as PET bottles and cups. The cup holders 235 may also have the function of accommodating and supporting the operator's mobile device.

[0037] <3. Display and Operation Panel> As shown in Figure 2, the rice transplanter 1 is equipped with a support section 60. The support section 60 supports the display unit 28 and the operating unit 29. The support section 60 is attached to two support columns 25 located on the right side of the bonnet 23. Details of the support section 60 will be described later. Because the display unit 28 is supported by the support section 60, the display unit 28 is positioned to the right of the steering wheel 22a. In other words, the rice transplanter 1 is equipped with a display unit 28 located to the side of the steering wheel 22a.

[0038] By positioning the display unit 28 to the side of the steering wheel 22a, the operator seated in the driver's seat 21 can view the display unit 28 without it being obstructed by the steering wheel 22a. This improves the visibility of the display unit 28.

[0039] The control unit 29 is provided separately from the display unit 28 and is supported by a support unit 60. The control unit 29 is positioned below the display unit 28. Because the control unit 29 is supported by the support unit 60, the control unit 29 is positioned to the right of the steering handle 22a. In other words, the rice transplanter 1 is equipped with a control unit 29 positioned to the side of the steering handle 22a, separate from the display unit 28. The details of the display unit 28 and the control unit 29 will be described below.

[0040] (3-1. Regarding the display unit) Figure 3 is an enlarged perspective view showing the display unit 28 and the operation unit 29 shown in Figures 1 and 2. The display unit 28 has a main body 281 and a display back cover 282. The display back cover 282 is attached to the back of the main body 281 (opposite the display screen) and supports the main body 281. The display back cover 282 is supported by the support unit 60 via a support bracket 283 (see Figures 10 and 11).

[0041] The main unit 281 comprises an information display unit 281A and a push button 281B. The information display unit 281A is, for example, a liquid crystal display device capable of color display and displays various types of information. The information display unit 281A may be composed of other display devices such as an organic EL (electro-luminescence) display.

[0042] 《3-1-1. Pressure Button》 Figure 4 is a front view of the main body 281 of the display unit 28, viewed from a direction perpendicular to the display screen of the information display unit 281A. The push buttons 281B are buttons that are physically pressed by the operator. The push buttons 281B are an example of an input unit 50 that receives various instruction inputs from the operator. Five push buttons 281B are arranged in a row at the top of the information display unit 281A. In the example in Figure 4, the push buttons 281B include a toggle button B1, an error list display button B2, a work setting button B3, a home button B4, and a back button B5. The toggle button B1, error list display button B2, work setting button B3, home button B4, and back button B5 are arranged from left to right in this order. Note that the number and arrangement of the push buttons 281B are not limited to the example in Figure 4.

[0043] Each time the toggle button B1 is pressed, the measurement start mark M1 (see Figure 5) displayed on the central display unit 281A1 of the information display unit 281A switches in the order of "A", "B", and "C". Details of the measurement start mark M1 will be described later. When the error list display button B2 is pressed, a list of errors that have occurred so far is displayed on the central display unit 281A1. The work setting button B3 is a button for setting work-related settings. When a predetermined item displayed on the central display unit 281A1 is selected using the select dial 284 (described later), pressing the work setting button B3 will directly transition to a screen for detailed settings of the above item.

[0044] Pressing the home button B4 transitions the display screen of the central display unit 281A1 to the home screen shown in Figure 5. Pressing the back button B5 transitions the current display screen of the central display unit 281A1 to the higher-level screen in the hierarchical structure.

[0045] 《3-1-2. Select Dial》 A select dial 284 is provided on the right side of the display back cover 282. In other words, the select dial 284 is located to the side of the display unit 28. The select dial 284 is also an example of an input unit 50. For example, by turning the select dial 284 clockwise or counterclockwise, the operator can select from multiple setting information to be displayed on the information display unit 281A or transition between display screens. The setting information mentioned above refers to, for example, information related to the settings of the rice transplanter 1. Examples of setting information will be described later. Furthermore, by pressing the select dial 284, it is possible to input an instruction to confirm the selected item.

[0046] Thus, the rice transplanter 1 is equipped with an input unit 50 for receiving instructions from the operator and for selecting setting information to be displayed on the display unit 28 (particularly the information display unit 281A). The input unit 50 also includes a push button 281B and a select dial 284 that can be rotated and pressed. Because the rice transplanter 1 is equipped with an input unit 50, the operator can make various settings by operating the input unit 50. In addition, setting information can be selected and displayed on the display unit 28 according to the operation of the input unit 50.

[0047] The top and right sides of the select dial 284 are covered by the dial cover 284a. The dial cover 284a may be positioned to cover only the top of the select dial 284, or it may be positioned to cover the top, right sides, and bottom of the select dial 284. In other words, it is sufficient that at least the top of the select dial 284 is covered by the dial cover 284a. In this case, the dial cover 284a not only protects the select dial 284 from rain, but also reduces the risk of the operator coming into contact with the select dial 284 when there is no intention to turn it. For example, when an operator moves the seedling mat of the spare seedling tray 24 to the seedling tray at the rear, the dial cover 284a prevents any part of the operator's body from coming into contact with the select dial 284.

[0048] Furthermore, if the lower part of the select dial 284 is covered by the dial cover 284a, rainwater may accumulate in the portion of the dial cover 284a that faces the select dial 284 downwards. For this reason, it is desirable that the dial cover 284a be shaped to cover at least the upper part of the select dial 284 and leave the lower part of the select dial 284 open, as shown in Figures 3 and 4.

[0049] As described above, the push button 281B, which serves as the input unit 50, is provided on the main body 281 of the display unit 28, and the select dial 284 is provided on the right side of the display back cover 282 of the display unit 28. In other words, the input unit 50 is integrally provided with the display unit 28. In this configuration, the display unit 28 is supported by the support unit 60, which will be described later, and no matter what rotational position the display unit 28 is positioned in, the positional relationship between the display unit 28 and the input unit 50 is maintained. Therefore, the operator can easily operate the input unit 50 regardless of the rotational position of the display unit 28.

[0050] 《3-1-3. Information display section》 As shown in Figure 4, the information display unit 281A has a central display unit 281A1 and a peripheral display unit 281A2.

[0051] <3-1-3-A. Peripheral Display Section> The peripheral display unit 281A2 is positioned around the central display unit 281A1. Icons (marks) corresponding to various types of information are illuminated on the peripheral display unit 281A2. This presents the operator with the information corresponding to the illuminated icon. The design and color of the displayed icons can be set as appropriate.

[0052] The information displayed on the peripheral display unit 281A2, that is, the information corresponding to the above icons, includes, for example, the following:

[0053] The information displayed on the left side of the information display unit 281A includes: work impossible error (illuminates when work is impossible), movement speed (for example, illuminates when moving at high speed), straight-line assist & PTO interlocking function ON, simple turning function ON, left marker deployed, etc. Straight-line assist refers to the function that allows the rice transplanter 1 to move in a straight line automatically without the operator operating the steering handle 22a. Simple turning refers to the function that allows the rice transplanter 1 to turn automatically. In simple turning, the operator operates the pedals.

[0054] The information displayed on the right side of the information display unit 281A includes warnings (illuminated when a warning is issued), on / off status of the fertilizer applicator 5, on / off status of the insecticide and fungicide sprayer, on / off status of the herbicide sprayer, and right marker deployment. The insecticide and fungicide sprayer and herbicide sprayer are optional devices that can be attached to the rice transplanter 1, and when attached, the corresponding icons are illuminated.

[0055] In this embodiment, the icons of the peripheral display unit 281A2 are displayed to the left and right of the central display unit 281A1, but the icons may also be displayed above and below the central display unit 281A1.

[0056] <3-1-3-B. Central display section> Figure 5 is an explanatory diagram showing an example of various information displayed on the central display unit 281A1. The central display unit 281A1 simultaneously displays measurement information P1, setting information P2, and status information P3. The display screen in Figure 5 is also referred to as the home screen.

[0057] Measurement information P1 is information measured as the work by the rice transplanter 1 progresses. For example, measurement information P1 includes information on the number of seedling mats used, the work area, and the amount of fertilizer used. Measurement information P1 is calculated by the control unit 90 (see Figure 9), which will be described later, based on the number of seedling mats used detected by the sensor unit 70 (see Figure 9), the vehicle's position detected by the positioning unit 27, and the rotation speed of the fertilizer motor detected by the sensor unit 70.

[0058] Measurement information P1 is displayed together with the measurement start point mark M1. The measurement start point mark M1 is a mark that indicates an arbitrary measurement start point set by the operator. There are three types of measurement start point mark M1 available, for example, "A", "B", and "C". By pressing the switch button B1 (see Figure 4), the measurement start point mark M1 is switched and displayed in the order of "A", "B", and "C". When "A" is displayed as the measurement start point mark M1, the information measured from the measurement start point corresponding to "A" is displayed as measurement information P1. Similarly, when "B" is displayed as the measurement start point mark M1, the information measured from the measurement start point corresponding to "B" is displayed as measurement information P1. Also, when "C" is displayed as the measurement start point mark M1, the information measured from the measurement start point corresponding to "C" is displayed as measurement information P1.

[0059] Setting information P2 is information related to the settings of the rice transplanter 1. For example, in the example in Figure 5, when seedling quantity assist is set to "on", each setting value such as the number of seedling mats per predetermined area, rotor depth, planting depth, and fertilizer application amount per predetermined area is displayed as setting information P2. Each of the above setting values ​​is set by selecting a predetermined item by rotating and pressing the select dial 284, and then selecting and confirming a numerical value by rotating and pressing the select dial 284.

[0060] The setting information P2 is displayed below the measurement information P1, simultaneously with (next to) the measurement information P1. This allows the operator to simultaneously check the setting information P2 and the measurement information P1 by looking at the display unit 28 (central display unit 281A1) while working with the rice transplanter 1. Therefore, compared to a configuration where the setting information P2 and the measurement information P1 are displayed on different screens, for example, the troublesome operation of switching between display screens is eliminated.

[0061] The configuration information P2 includes page markers M2. Page markers M2 indicate which page of the entire screen the screen currently displayed on the central display unit 281A1 corresponds to. In the example in Figure 5, it indicates that the screen currently displayed is page 1 / 4 (page 1 of 4 pages). In other words, the number of dots indicated by page markers M2 represents the total number of pages, and the position of the blacked-out dot from the left edge indicates the number of pages being displayed. Note that if any warning is to be displayed, a warning message may be displayed instead of page markers M2.

[0062] Status information P3 is information about the status of the rice transplanter 1. For example, as shown in Figure 5, status information P3 includes fuel level information P31, hour meter P32, straight-line assist setting information P33, communication information P34, and time information P35. Status information P3 is displayed above measurement information P1 and simultaneously with (next to) measurement information P1.

[0063] Fuel level information P31 shows the remaining fuel level. Hour meter P32 shows the operating time since the rice transplanter 1 was purchased. Straight-line assist setting information P33 shows whether the straight-line assist function is on or off. The on / off status of the straight-line assist function is indicated, for example, by the illumination / exiting of the corresponding icon, or by displaying the above icon in a different color. Time information P35 shows the current time.

[0064] Communication information P34 indicates the positioning method (RTK / DGNSS) used by the positioning unit 27 (see Figure 1) and the quality of communication with the positioning satellite. RTK refers to the Real-Time Kinematic method, and DGNSS refers to the Differential GNSS (Global Navigation Satellite System) method. In Figure 5, DGNSS is indicated by the notation GNSS. The quality of communication is indicated as follows: For example, when communication is good, the positioning satellite icon included in communication information P34 is displayed in green; when communication is poor, the icon is displayed in red; and when communication is between good and poor, the icon is displayed in yellow. Note that the color used to display the icon is not limited to the colors described above and may be set as appropriate.

[0065] In this embodiment, the setting information P2 is displayed below the measurement information P1, but the setting information P2 may also be displayed above the measurement information P1 (for example, between the measurement information P1 and the status information P3). Alternatively, for example, the measurement information P1 may be displayed to the left of the central display unit 281A1, and the setting information P2 may be displayed to the right of the central display unit 281A1. In other words, in the central display unit 281A1, the measurement information P1 and the setting information P2 may be displayed simultaneously (side by side) in the vertical or horizontal direction.

[0066] (3-2. Regarding the control panel) As shown in Figure 3, the control unit 29 includes a first control unit 291, a second control unit 292, and an operation support unit 293. The first control unit 291 receives input for settings related to the automatic movement of the rice transplanter 1. The second control unit 292 receives instructions for predetermined operations to the rice transplanter 1. The second control unit 292 is located to the right of the first control unit 291. In other words, the first control unit 291 and the second control unit 292 are arranged side by side in the left-right direction. The second control unit 292 may also be located to the left of the first control unit 291.

[0067] The operation support section 293 supports the operation section 29. Specifically, the operation support section 293 has a first operation support section 293A and a second operation support section 293B. The first operation support section 293A supports the first operation section 291 from below. The second operation support section 293B supports the second operation section 292 from below. The first operation support section 293A and the second operation support section 293B are constructed as separate parts, but may be constructed as an integral part. The details of the first operation section 291 and the second operation section 292 will be described below.

[0068] 《3-2-1. 1st operation section》 Figure 6 is a front view of the first operating section 291 as seen from the direction in which the buttons are pressed. The first operating section 291 includes an AUTO button 2911, an A button 2912, and a B button 2913. The A button 2912 and the B button 2913 are arranged side by side below the central AUTO button 2911.

[0069] The AUTO button 2911 is used to instruct the start of automatic operation of the rice transplanter 1 based on satellite positioning. Buttons A 2912 and B 2913 are pressed when creating a reference line that will serve as the basis for automatic operation. For example, when the satellite signal positioning level is good (for example, when lamp L1 is lit green), moving the rice transplanter 1 to the work start position and pressing button A 2912 completes the registration of point A (lamp L2 lights up). Then, moving the rice transplanter 1 to the work end position of the process and pressing button B 2913 completes the registration of point B (lamp L3 lights up). The control unit 90, described later, then creates a line segment connecting points A and B as the reference line. When the operator manually turns the rice transplanter 1 and presses the AUTO button 2911 at a predetermined timing, lamp L4 around the AUTO button 2911 lights up, and automatic operation of the rice transplanter 1 begins. In other words, the rice transplanter 1 automatically starts moving along the reference line. From there, the rice transplanter 1 repeatedly performs manual turning and automatic movement.

[0070] Figure 7 is a front view showing another example of the first operating unit 291. In addition to the configuration in Figure 6, the first operating unit 291 may further have a left button 2914 and a right button 2915. The left button 2914 is pressed when making fine adjustments by shifting the reference line to the left by a predetermined amount. The right button 2915 is pressed when making fine adjustments by shifting the reference line to the right by a predetermined amount. The operation related to automatic driving is the same as the operation of the first operating unit 291 in Figure 6.

[0071] 《3-2-2.Second operation section》 Figure 8 is a front view of the second operating unit 292 as seen from the direction of button pressing. The second operating unit 292 is also called a multi-switch because it has multiple switches. Specifically, the second operating unit 292 has a planting unit rotation interlocking function on / off button 2921, a rotor on / off button 2922, a planting depth "shallow" setting button 2923, a planting depth "deep" setting button 2924, a rotor "shallow" setting button 2925, a rotor "deep" setting button 2926, a one-shot button 2927, and a marker storage button 2928. These are all press buttons for items that the operator wants to operate immediately.

[0072] The planting unit rotation linkage function on / off button 2921 is a button for setting the planting unit rotation linkage function on or off. The planting unit rotation linkage function is a function that automatically raises and lowers the planting unit 3, turns the planting clutch on / off (starts / stops planting), and deploys / retracts the marker 34 in response to the operator's operation of the steering handle 22a. Each time the planting unit rotation linkage function on / off button 2921 is pressed, the planting unit rotation linkage function is switched on or off. When the planting unit rotation linkage function is set to "on", the lamp in the upper right of the planting unit rotation linkage function on / off button 2921 lights up. Note that in Figure 8, the planting unit rotation linkage function on / off button 2921 is labeled "Sukoyaka Turn On / Off", but this is just an example, and other labels may be used.

[0073] The rotor on / off button 2922 is used to turn the rotor 33 on or off, that is, to set whether or not to use the rotor 33. Each time the rotor on / off button 2922 is pressed, the rotor 33 is switched on or off. When the rotor 33 is set to "on", the rotor 33 moves to a preset height position, and the lamp to the upper right of the rotor on / off button 2922 lights up.

[0074] The "shallow" planting depth setting button 2923 and the "deep" planting depth setting button 2924 are buttons for adjusting the planting depth. Each press of the "shallow" planting depth setting button 2923 reduces the planting depth by a predetermined amount. Conversely, each press of the "deep" planting depth setting button 2924 increases the planting depth by a predetermined amount.

[0075] The rotor "shallow" setting button 2925 and the rotor "deep" setting button 2926 are buttons for adjusting the height (depth) of the rotor 33. Each time the rotor "shallow" setting button 2925 is pressed, the depth of the rotor 33 is set to be shallower (higher) by a predetermined amount. Conversely, each time the rotor "deep" setting button 2926 is pressed, the depth of the rotor 33 is set to be deeper (lower) by a predetermined amount.

[0076] When the one-shot button 2927 is pressed, the planting unit 3 moves to a preset height. When the marker storage button 2928 is pressed, the left and right markers 34 are retracted.

[0077] As described above, the operation unit 29 includes a first operation unit 291 and a second operation unit 292. In this configuration, the operator can set up automatic driving by operating the first operation unit 291. The operator can also make the rice transplanter 1 perform predetermined actions by operating the second operation unit 292.

[0078] Furthermore, the first operating section 291 and the second operating section 292 are arranged side by side (in the left-right direction), resulting in a unified arrangement of the operating section 29 as a whole. This makes it easier for the operator to operate both the first operating section 291 and the second operating section 292.

[0079] <4. Regarding the configuration of the control system> Figure 9 is a block diagram showing the configuration of the control system of the rice transplanter 1. In addition to the display unit 28 and operation unit 29 described above, the rice transplanter 1 further includes a sensor unit 70, an actuator unit 80, a control unit 90, and a storage unit 100.

[0080] The sensor unit 70 is a collection of sensors that detect predetermined information in the rice transplanter 1. For example, sensors that detect the rotation speed of the axle of the rice transplanter 1, sensors that detect the rotation speed of the star wheel provided on the seedling tray of the seedling tray 31 (see Figure 1), and sensors that detect the rotation speed of the fertilizer motor of the fertilizer applicator 5 are included in the sensor unit 70.

[0081] The actuator section 80 is a collection of mechanisms that operate various parts of the rice transplanter 1. For example, the lifting mechanism 4, the height adjustment mechanism for the rotor 33, the fertilizer application drive mechanism (including the fertilizer motor) of the fertilizer application device 5, the left and right tilt adjustment mechanism for the seedling loading device 31, and the deployment mechanism for the marker 34 are all included in the actuator section 80. The actuator section 80 also includes actuators for automatic driving. Actuators for automatic driving refer to various actuators that are operated during automatic driving, and include, for example, the actuator that steers the steering wheel 22a and the actuator that changes the speed of the transmission device of the transmission section 1d.

[0082] The control unit 90 is composed of an electronic control unit, also known as an ECU (Electronic Control Unit), and controls the drive of each part of the rice transplanter 1. For example, the operation of the traveling body 2 (forward, reverse, stop, and turn, etc.) and the operation of the planting unit 3 (lifting, lowering, driving, and stopping, etc.) are controlled by the control unit 90. The control unit 90 also controls the automatic driving actuators included in the actuator unit 80 so that the rice transplanter 1 travels along a predetermined travel path, based on the vehicle position information measured by the positioning unit 27. Furthermore, the control unit 90 controls the display of the display unit 28 based on the operation of the input unit 50 and the operation unit 29. The control unit 90 can control each part of the rice transplanter 1 by executing the operation program stored in the storage unit 100.

[0083] The control unit 90 can acquire predetermined information based on the detection results from the sensor unit 70. For example, the control unit 90 can calculate the travel distance of the rice transplanter 1 based on the number of rotations of the axle per unit time. The control unit 90 can also calculate the amount of seedling mat used based on the number of rotations of the star wheel.

[0084] The memory unit 100 is a memory that stores various types of information and is composed of RAM (Random Access Memory), ROM (Read Only Memory), non-volatile memory, etc. The memory unit 100 stores the operation program of the control unit 90, information detected by the sensor unit 70, various setting values ​​set by the operation of the input unit 50 (for example, the select dial 284) and the operation unit 29, and so on.

[0085] <5. Regarding the support structure> Next, the details of the support section 60 that supports the display unit 28 and the operation unit 29 will be described. Figure 10 is a perspective view showing the schematic configuration of the support section 60. Figure 11 is an exploded perspective view of the display unit 28, the operation unit 29, and the support section 60. As shown in Figures 10 and 11, the support section 60 has a first shaft section 61, a second shaft section 62, and a support body section 63.

[0086] The first shaft portion 61 extends horizontally and supports the display portion 28 so that it can rotate vertically. Here, the horizontal direction is any direction perpendicular to the vertical direction. Therefore, the horizontal direction may be the left-right direction, or it may be a direction that is perpendicular to the vertical direction and intersects with the left-right direction. In the following explanation, the horizontal direction will be described as the left-right direction.

[0087] The first shaft portion 61 is made up of bolts or the like that extending in the left-right direction. The first shaft portion 61 is provided by passing through two upper through holes 631a in the support body portion 63 and two through holes (not shown) provided in the support bracket 283 of the display unit 28 in the left-right direction, and is fixed with nuts. The support bracket 283 is fixed to the display back cover 282 of the display unit 28 with bolts or the like. The two upper through holes 631a are provided in the support body portion 63, on the upper part of the two upper support pieces 631, respectively. Each upper support piece 631 is positioned on both the left and right sides of the support bracket 283, sandwiching the support bracket 283 from both sides. The lower ends of each upper support piece 631 are connected in the left-right direction by the first connecting portion 633. The first connecting portion 633 is provided with a first hole portion 633a that passes through in the vertical direction.

[0088] The second shaft portion 62 extends horizontally and supports the operating portion 29 so that it can rotate vertically. For example, the second shaft portion 62 is made up of a bolt or the like that extends horizontally. The second shaft portion 62 is positioned below the first shaft portion 61 and parallel to the first shaft portion 61. The second shaft portion 62 is provided by passing through two lower through holes 632a provided in the support body portion 63 and a plurality of openings 293p provided in the operating support portion 293 in the horizontal direction. The two lower through holes 632a are provided in the support body portion 63, respectively, in two lower support pieces 632. The two lower support pieces 632 sandwich the supported portion 293C provided in the operating support portion 293 from the left and right directions. The supported portion 293C is provided at the bottom of the first operating support portion 293A and the second operating support portion 293B of the operating support portion 293. Each lower support piece 632 is connected in the left-right direction by the second connecting portion 634.

[0089] The support body 63 supports the first shaft portion 61 and the second shaft portion 62. The first shaft portion 61 is inserted into the upper through hole 631a of each upper support piece 631, and the second shaft portion 62 is inserted into the upper through hole 631a of each lower support piece 632, thereby supporting the first shaft portion 61 and the second shaft portion 62 by the support body 63.

[0090] The first connecting portion 633 of the support body 63 is connected to the third connecting portion 635 via the second connecting portion 634. The third connecting portion 635 is positioned parallel to the first connecting portion 633 and below it. The third connecting portion 635 is provided with a second hole 635a that penetrates in the vertical direction. The first connecting portion 633, the second connecting portion 634, and the third connecting portion 635 are formed as thin plates, but their thickness, size, shape, etc., can be changed as appropriate.

[0091] As shown in Figure 10, the support body 63 is attached to the mounting frame 65 via the arm 64. The mounting frame 65 is positioned extending in the front-rear direction. The mounting frame 65 is attached to two front and rear support columns 25 located on the right side of the bonnet 23 (see Figures 1 and 2) via mounting fixtures 65a.

[0092] The arm 64 has an arm body 641 and a flat plate 642. The arm body 641 extends diagonally upward relative to the mounting frame 65. Hereinafter, the direction in which the arm body 641 extends will also be referred to as the longitudinal direction. As shown in Figure 11, the arm body 641 has a recessed portion 641a that extends longitudinally and has a semicircular or U-shaped cross-section. The communication cable CA (see Figure 10) is routed through the recessed portion 641a. The communication cable CA refers to the bundle of wiring (harness) connecting the display unit 28, the operation unit 29, and the select dial 284 (see Figure 3, etc.) and the control unit 90 (see Figure 9). With the cable CA housed in the recessed portion 641a, the flat plate 642 is placed over the recessed portion 641a and fixed with bolts, etc., so that the cable CA is routed through the inside of the arm 64. This reduces the flapping of the cable CA.

[0093] A first insertion portion 6411 is provided at one end of the arm body portion 641, and a second insertion portion 6412 is provided at the other end. The first insertion portion 6411 is located above the second insertion portion 6412. The first shaft insertion portion 6411 is provided with a first insertion hole 6411a through which the third shaft portion 66 is inserted. The first insertion hole 6411a penetrates the first insertion portion 6411 in the vertical direction. The second insertion portion 6412 is provided with a second insertion hole 6412a through which the fourth shaft portion 67 is inserted. The second insertion hole 6412a penetrates the second insertion portion 6412 in the vertical direction.

[0094] The first insertion portion 6411 of the arm 64 is positioned between the first connecting portion 633 and the third connecting portion 635 of the support body portion 63. A bolt, which serves as the third shaft portion 66, is inserted vertically into the second hole 635a of the third connecting portion 635, the first insertion hole 6411a of the first insertion portion 6411, and the first hole 633a of the first connecting portion 633, and tightened with a nut. As a result, the support body portion 63 is mounted so as to be rotatable in the left-right direction relative to the arm 64, with the third shaft portion 66 as its axis.

[0095] The second insertion portion 6412 of the arm 64 is rotatably attached to the rear end portion 651 of the mounting frame 65. More specifically, the second insertion hole 6412a of the second shaft insertion portion 6412 is aligned with a hole (not shown) provided in the rear end portion 651 of the mounting frame 65, and a bolt serving as the fourth shaft portion 67 is inserted vertically into the hole and the second insertion hole 6412a and tightened with a nut. As a result, the arm 64 is mounted to the mounting frame 65 so as to be rotatable in the left-right and front-back directions around the fourth shaft portion 67.

[0096] Figures 12A and 12B are side views showing the display unit 28 and the operation unit 29 before and after changing their orientation relative to the support unit 60 (particularly the support body 63). As described above, the display unit 28 is rotatably supported on the first shaft 61, and the first shaft 61 is supported on the support body 63. This makes it possible to change the orientation of the display unit 28 relative to the support body 63. Specifically, by loosening the nut attached to the bolt of the first shaft 61, the display unit 28 can be rotated vertically relative to the support body 63, with the horizontally extending first shaft 61 as the central axis. By tightening the nut at a predetermined vertical rotation position of the display unit 28, the display unit 28 is held in that rotation position.

[0097] Similarly, the operating unit 29 is rotatably supported on the second shaft 62, and the second shaft 62 is supported on the support body 63. This makes it possible to change the orientation of the operating unit 29 relative to the support body 63. Specifically, by loosening the nut attached to the bolt of the second shaft 62, the operating unit 29 can be rotated vertically relative to the support body 63, with the horizontally extending second shaft 62 as the central axis. Moreover, the operating unit 29 can be rotated vertically independently of the vertical rotation of the display unit 28. By tightening the nut at a predetermined vertical rotation position of the operating unit 29, the operating unit 29 is held in that rotation position. Furthermore, if the first operating section 291 and the second operating section 292 of the second operating section 29 are configured as separate components, and the first operating support section 293A and the second operating support section 293B are configured as separate components, it becomes possible to rotate the first operating section 291 and the second operating section 292 independently, thereby making their vertical rotation positions different from each other.

[0098] Figures 13A and 13B are schematic plan views showing the state before and after the display unit 28 and the operation unit 29 rotate around the third shaft 66. As described above, the support body 63 is mounted so as to be rotatable in the left-right direction relative to the arm 64 around the third shaft 66. Therefore, by loosening the nuts attached to the bolts of the third shaft 66, the display unit 28, the operation unit 29, and the support body 63 can be rotated integrally in the left-right direction relative to the arm 64 around the third shaft 66. By tightening the nuts to fix the display unit 28 and the operation unit 29 at predetermined rotational positions relative to the arm 64, the display unit 28 and the operation unit 29 are held in those rotational positions.

[0099] Figure 14 is a schematic plan view showing the state after the display unit 28 and the operating unit 29 have rotated around the fourth shaft 67 from the state shown in Figure 13A. As described above, the arm 64 is mounted to the mounting frame 65 so as to be rotatable in the left-right and front-back directions around the fourth shaft 67. Therefore, by loosening the nut attached to the bolt of the fourth shaft 67, the display unit 28, the operating unit 29, the support body 63, and the arm 64 can be rotated integrally around the fourth shaft 67 in the left-right and front-back directions relative to the mounting frame 65. By tightening the nut to fix the arm 64 at a predetermined rotational position relative to the mounting frame 65, the display unit 28 and the operating unit 29 are held in that rotational position.

[0100] As described above, the display unit 28 and the operation unit 29 are each supported by the support unit 60 in a manner that allows their orientation to be changed.

[0101] In this configuration, the orientation of the display unit 28 and the control unit 29 can be changed separately according to the body shape (e.g., height) of the worker seated in the driver's seat 21 (see Figure 1, etc.) (see Figures 12A and 12B). Therefore, the display unit 28 can be positioned in a way that is easy for the worker seated in the driver's seat 21 to see, and the control unit 29 can be positioned in a way that is easy for the worker to operate. In other words, the orientation of the display unit 28 and the control unit 29 can be adjusted to suit the worker seated in the driver's seat 21 (suitable for the worker's body shape).

[0102] In particular, because the display unit 28 can change its orientation relative to the support unit 60, the effect of improving the visibility of the display unit 28 by positioning it to the side of the steering wheel 22a can be obtained regardless of the operator's physique (especially height). In this respect, the configuration of this embodiment, in which the orientation of the display unit 28 can be changed, is more effective than a configuration in which the orientation of the display unit 28 is fixed.

[0103] From the viewpoint of ensuring that the display unit 28 and the operation unit 29 are positioned appropriately according to the worker's physique, it is desirable that the display unit 28 and the operation unit 29 can each be rotated vertically to change their orientation. In this respect, as in this embodiment, it is desirable that the display unit 28 and the operation unit 29 are each supported by the support unit 60 so as to be rotatable vertically.

[0104] In particular, from the viewpoint of reliably realizing a configuration in which the support portion 60 supports the display portion 28 so as to be rotatable in the vertical direction and supports the operation portion 29 so as to be rotatable in the vertical direction, it is desirable that the support portion 60 has the following configuration. That is, it is desirable that the support portion 60 has a first shaft portion 61 that supports the display portion 28 so as to be rotatable in the vertical direction, a second shaft portion 62 that supports the operation portion 29 so as to be rotatable in the vertical direction, and a support body portion 63 that supports the first shaft portion 61 and the second shaft portion 62.

[0105] As shown in Figures 1 and 2, the rice transplanter 1 is equipped with a support column 25. The support column 25 is located, for example, on the right side of the bonnet 23, that is, to the side of the operating column 22 where the steering handle 22a is located, and supports the spare seedling tray 24. In order to reliably realize the configuration in which the display unit 28 and the operating unit 29 are located to the side of the steering handle 22a, it is desirable that the support portion 60 that supports the display unit 28 and the operating unit 29 be arranged as follows. That is, it is desirable that the support portion 60 be attached to the support column 25 (via a mounting frame 65).

[0106] <6. Supplementary Information> In this embodiment, an example has been described in which the second shaft portion 62 of the support portion 60 is positioned below the first shaft portion 61, but the embodiment is not limited to this example. For example, the second shaft portion 62 may be positioned above the first shaft portion 61. In other words, the second shaft portion 62 may be positioned offset vertically from the first shaft portion 61. When the second shaft portion 62 is positioned above the first shaft portion 61, the operating portion 29, which is rotatably supported by the second shaft portion 62, is positioned above the display portion 28, which is rotatably supported by the first shaft portion 61. Therefore, it can also be said that the operating portion 29 only needs to be positioned offset vertically from the display portion 28.

[0107] In this embodiment, an example has been described in which the display unit 28 and the operation unit 29 are positioned to the right of the steering wheel 22a, but the arrangement is not limited to this. For example, to accommodate left-handed workers, the display unit 28 and the operation unit 29 may be positioned to the left of the steering wheel 22a.

[0108] In this embodiment, an example has been described in which the support section 60 that supports the display unit 28 and the operation unit 29 is attached to the support column 25 that supports the spare seedling tray 24, but the invention is not limited to this example. For example, a dedicated support column may be erected on the floor 2f of the traveling machine body 2, and the support section 60 may be attached to the support column.

[0109] In this embodiment, a rice transplanter 1 was used as an example of a work vehicle, but the work vehicle is not limited to a rice transplanter 1. For example, the configuration described in this embodiment can also be applied to agricultural work vehicles such as tractors, combine harvesters, and seedling transplanters, as well as civil engineering and construction work vehicles and snowplows.

[0110] <7. Addendum> The work vehicle described in this embodiment can also be described as follows:
