Modes for Carrying Out the Invention

[0024] Hereinafter, the directions indicated by the arrows U, D, F, B, L, and R in the figures will be defined as the upward, downward, forward, backward, leftward, and rightward directions, respectively, for the description.

[0025] Hereinafter, the walking-type management machine 10 according to the first embodiment of the present invention will be described.

[0026] The walking-type management machine 10 shown in FIG. 1 includes a body frame 11, tires 12, an engine 13, a fuel tank 14, a bonnet 15, a cover 16, a transmission case 17, a rotary 18, a resistance bar 19, a work plate 20, a clutch mechanism 21, a handle frame 22, a handle connecting portion 23, a handle 24, a clutch lever 25, a display mechanism 26, and the like.

[0027] The body frame 11 is a member formed by appropriately bending a plate material. The body frame 11 is supported by a pair of left and right tires 12. The engine 13 is placed on the body frame 11. The fuel tank 14 is arranged behind the engine 13. The engine 13 and the fuel tank 14 are covered by the bonnet 15. On the left side of the engine 13, a cover 16 that covers the clutch mechanism 21 for transmitting the power of the engine 13 to the transmission case 17 is provided.

[0028] The transmission case 17 is a case that houses a speed change mechanism 17a for transmitting the power from the engine 13 to the tires 12 and the rotary shaft 17b. The rotary 18 includes tilling claws 18a fixed to the rotary shaft 17b and a tilling cover 18b that covers the tilling claws 18a from above. The resistance bar 19 and the work plate 20 are attached to the tilling cover 18b.

[0029] The clutch mechanism 21 is for switching the transmission of power from the engine 13 to the speed change mechanism 17a (the tires 12 and the tilling claws 18a). As the clutch mechanism 21 of the present embodiment, a so-called belt tension clutch that can transmit power by applying tension to a belt wound around a pulley is assumed.

[0030] Above the tilling cover 18b, a handle frame 22 is arranged. The handle frame 22 is a frame for supporting the handle 24. The handle frame 22 is formed to extend rearward and upward. At the rear upper end of the handle frame 22, the handle 24 is attached via a handle connecting part 23.

[0031] The handle 24 is for the user to operate the walking type management machine 10. The handle 24 is formed to extend rearward and upward from the handle connecting part 23. As shown in FIG. 2, the handle 24 is formed in a substantially triangular frame shape in plan view. The handle 24 is formed by appropriately bending a member having a substantially circular cross section. The handle 24 includes side portions 24a, a rear portion 24b, and a cross member 24c.

[0032] The side portion 24a shown in FIG. 2 is a portion constituting the left and right side portions of the handle 24. The side portions 24a extend rearward (rearward and upward) from the handle connecting part 23 so as to be spaced apart from each other in the left and right directions.

[0033] The rear portion 24b is a portion constituting the rear portion of the handle 24. The rear portion 24b extends in the left and right directions so as to connect the rear ends of the left and right side portions 24a. The rear portion 24b is gripped by the fingers of the user.

[0034] The cross member 24c is a portion connecting the middle portions in the front - rear direction of the left and right side portions 24a. The cross member 24c is provided so as to be located rearward of the central portion in the front - rear direction of the handle 24. By providing the cross member 24c, the handle 24 can be strengthened.

[0035] The clutch lever 25 shown in FIGS. 1 and 2 is a lever capable of operating the clutch mechanism 21. The clutch lever 25 is connected to the clutch mechanism 21 via a cable (not shown). The clutch lever 25 is provided between the middle parts in the front-rear direction of the left and right side parts 24a (behind the transverse part 24c). As shown in FIG. 1, when the user operates the clutch lever 25 to grip it, the clutch lever 25 rotates clockwise in a left side view with respect to the left and right side parts 24a. Also, when the user releases the hand from the clutch lever 25, the clutch lever 25 automatically returns to the position before the operation.

[0036] The display mechanism 26 is for displaying predetermined information (such as information regarding the inclination angle of the walking type management machine 10). The configuration of the display mechanism 26 will be described later.

[0037] The walking type management machine 10 configured as described above has the clutch lever 25 operated, so that tension is applied to the belt and the clutch mechanism 21 is actuated. Thereby, the power from the engine 13 is transmitted to the tire 12 and the rotating shaft 17b via the transmission mechanism 17a. Thus, the walking type management machine 10 can cultivate the field A by rotating the tilling claws 18a while traveling as shown in FIG. 3. Also, during tilling, the resistance bar 19 can be inserted into the field A to generate resistance, and the forward speed and tilling depth of the walking type management machine 10 can be adjusted. In this way, the walking type management machine 10 can perform the tilling operation.

[0038] Also, when the operation of the clutch lever 25 of the walking type management machine 10 is released, the clutch lever 25 automatically returns to the position before the operation, the application of tension to the belt is stopped, and the operation of the clutch mechanism 21 is stopped. Thereby, the rotation of the tire 12 and the tilling claws 18a is stopped, and the tilling operation can be terminated. Thus, in this embodiment, an example is shown in which a so-called dead man type clutch is adopted as the clutch mechanism 21, which operates while the user is gripping the clutch lever 25 and stops operating when the hand is released and the operation of the clutch lever 25 is released.

[0039] In addition, in this embodiment, an example of performing tillage work using the rotary tiller 18 has been described. However, the walking-type management machine 10 can be equipped with various other work implements to perform various operations (for example, ridging work, multi-operation, land leveling work, etc.).

[0040] Here, when performing work using the walking-type management machine 10, it is assumed that the walking-type management machine 10 will tilt according to the work. For example, when performing tillage work using the rotary tiller 18 as in the walking-type management machine 10 of this embodiment, since the tillage claws 18a enter the ground, the rear part of the walking-type management machine 10 tilts downward. In particular, since the walking-type management machine 10 of this embodiment is equipped with tires 12 for traveling on the field A, it tilts so as to rotate in the clockwise direction in a left side view (see FIG. 3) around the contact point between the tire 12 and the field A. The depth of tillage of the field A by the tillage claws 18a (tillage depth D) becomes deeper as the tilt angle α of the walking-type management machine 10 with respect to the front-rear direction increases. The user can till the field A at a desired tillage depth D (for example, a tillage depth D suitable for the crops cultivated in the field A) by moving the handle 24 up and down to adjust the tilt angle α of the walking-type management machine 10.

[0041] However, when a user who is not familiar with the operation of the machine performs tillage work, there is a concern that the above-described adjustment of the tillage depth D (tilt angle α) cannot be performed appropriately. Furthermore, when a user who is not familiar with the operation of the machine performs tillage work, it is expected that it will be difficult not only to adjust the tillage depth D but also to keep the vehicle body of the walking-type management machine 10 horizontally level left and right. Therefore, the walking-type management machine 10 according to this embodiment is provided with a display mechanism 26 to make it easier for users who are not familiar with the operation of the machine, etc. to adjust the tillage depth D (tilt angle α) and the tilt angle β (see FIG. 4) of the walking-type management machine 10 with respect to the left-right direction. The display mechanism 26 will be described below.

[0042] The display mechanism 26 is for displaying information regarding the tilt angles α and β (hereinafter referred to as "angle information"). The angle information includes various information regarding the tilt angles α and β. For example, the angle information includes not only the values of the tilt angles α and β themselves, but also various information such as the tillage depth D calculated from the tilt angles α and β, a standard for whether the tilt angles α and β are suitable for a predetermined operation, and a notification prompting adjustment of the tilt angles α and β.

[0043] As shown in FIGS. 1, 2, and 5, the display mechanism 26 includes a terminal 27 and a mounting portion 28.

[0044] The terminal 27 can input and output various information. The terminal 27 can be a portable and small-sized one. As the terminal 27, for example, a smartphone (mobile phone) can be adopted. Also, the terminal 27 is not limited to a smartphone, and various terminals such as a tablet terminal can be adopted. The terminal 27 is provided on the handle 24 via the mounting portion 28 described later. As shown in FIG. 5(b), the terminal 27 includes a speaker 27a, a tilt sensor 27b, a touch panel 27c, and a control means 27d.

[0045] The speaker 27a is for outputting sound.

[0046] The tilt sensor 27b is for detecting the tilt of the terminal 27. As the tilt sensor 27b, an appropriate gyro sensor or the like can be adopted. The tilt sensor 27b can detect the tilt angle of the terminal 27 with respect to an arbitrary direction (for example, the tilt angle with respect to the front-rear direction, the tilt angle with respect to the left-right direction, etc.).

[0047] The touch panel 27c shown in FIG. 5 is for inputting and outputting information. The touch panel 27c can display predetermined information. Also, various information can be input to the touch panel 27c by a touch operation of the user.

[0048] The control means 27d is for controlling the terminal 27. The control means 27d is mainly composed of an arithmetic processing unit such as a CPU and a storage device in which programs executable by the arithmetic processing unit are stored. The control means 27d is electrically connected to the speaker 27a, the tilt sensor 27b, and the touch panel 27c.

[0049] The control means 27d can cause the speaker 27a to output a predetermined sound by transmitting a signal to the speaker 27a. Further, the control means 27d can acquire the tilt angle of the terminal 27 by receiving a signal from the tilt sensor 27b. As will be described later, the control means 27d can calculate (detect) the tilt angles α and β of the vehicle body based on the acquired tilt angle of the terminal 27. The control means 27d can cause the touch panel 27c to display desired information by transmitting a signal to the touch panel 27c. Further, the control means 27d can acquire the operation result of the touch panel 27c by receiving a signal from the touch panel 27c.

[0050] The attachment portion 28 shown in FIGS. 1 and 2 can attach the terminal 27. The attachment portion 28 is provided on the steering wheel 24. In the present embodiment, an example in which the attachment portion 28 is provided at the center in the left - right direction of the cross - frame portion 24c is shown. The attachment portion 28 can detachably attach the terminal 27. As an attachment mode of the terminal 27 by the attachment portion 28, for example, a mode of attaching the terminal 27 by sandwiching the side portion of the terminal 27 with an appropriate arm can be adopted. Also, for example, a mode of attaching the terminal 27 using a magnet or a mode of attaching the terminal 27 with an appropriate belt (band) or the like can also be adopted.

[0051] The attachment portion 28 can attach the terminal 27 with the touch panel 27c facing rearward (rear - upper). Thereby, the touch panel 27c of the terminal 27 attached to the attachment portion 28 can be directed toward the user operating the walking - type management machine 10 (in a direction visible to the user).

[0052] Using the terminal 27 attached to the vehicle body as described above, the tilt angles α and β of the walking-type management machine 10 can be detected. Specifically, for example, with the walking-type management machine 10 placed on a horizontal ground (a state where the tires 12 and the tilling claws 18a are in contact with the horizontal ground) as a reference, the tilt of the walking-type management machine 10 is detected by the tilt sensor 27b, thereby enabling the detection of the tilt angles α and β. Further, based on the detected tilt angle α and the origin of the walking-type management machine 10 (for example, the dimensions and positional relationships of the tires 12 and the rotary tiller 18, etc.), the tillage depth D of the walking-type management machine 10 can be calculated (estimated).

[0053] In the display mechanism 26 configured as described above, by causing the touch panel 27c of the terminal 27 to display a display screen 30 as shown in FIG. 6, information (angle information) regarding the tilt angles α and β can be displayed. Hereinafter, the display screen 30 will be described.

[0054] The display screen 30 is a screen for displaying angle information. For example, when the user performs an appropriate operation using the touch panel 27c, the control means 27d generates the display screen 30 and displays it on the touch panel 27c. The display screen 30 includes a selection section 31, a target display section 32, a first tilt angle display section 33, and a second tilt angle display section 34.

[0055] The selection section 31 is a part for selecting the type of crop to be cultivated in the field A. The selection section 31 is configured to be operable by tapping. When the selection section 31 is tapped, a plurality of crop types that can be selected by the user are displayed on the display screen 30.

[0056] Here, in the terminal 27, the type of crop, the value of the tillage depth D suitable for the crop, and the inclination angle α of the walking type management machine 10 when performing tillage work at the tillage depth D are stored in advance in an associated manner. FIG. 5(c) shows an example of the values such as the tillage depth D stored in the terminal 27. In the example shown in FIG. 5(c), the types of crops (especially vegetables) are classified into categories of "root vegetables", "leafy vegetables", and "fruit vegetables", and the suitable tillage depth D and the like for each are shown. Note that the numerical values in the figure are described as an example for explanation, and actually, based on experiments and the like, the values suitable for each crop are determined.

[0057] When the selection unit 31 shown in FIG. 6 is tapped, a plurality of crop types shown in FIG. 5(c) are displayed, and the user can select any crop. When the user selects a desired crop (the crop to be cultivated in field A) by a tap operation, the selected crop is displayed on the selection unit 31.

[0058] The target display unit 32 is a part that displays the inclination angle α at which tillage work can be performed at the tillage depth D suitable for cultivating the crop displayed on the selection unit 31. The display of the target display unit 32 is appropriately updated by the control means 27d according to the selection of the crop type on the selection unit 31. Specifically, when a crop is selected on the selection unit 31, the control means 27d acquires the inclination angle (see FIG. 5(c)) stored in association with the crop selected on the selection unit 31. By causing the control means 27d to display the thus acquired inclination angle α on the target display unit 32, the target value of the inclination angle α corresponding to the selection on the selection unit 31 can be displayed.

[0059] The first inclination angle display unit 33 is a part that displays the inclination angle α of the vehicle body with respect to the front-rear direction detected by the inclination sensor 27b. An illustration 33a, a scale 33b, an auxiliary line 33c, and a line 33d are displayed on the first inclination angle display unit 33.

[0060] The illustration 33a is an image schematically showing how the walking type management machine 10 looks when viewed from the side. By appropriately tilting and displaying this image, the user can intuitively understand how the walking type management machine 10 is tilted with respect to the front-rear direction.

[0061] The scale 33b indicates the value of the tilt angle α. The scale 33b is displayed on the left and right sides of the illustration 33a respectively. The scale 33b in FIG. 6 sets the tilt angle α of the vehicle body to 0 when the walking type management machine 10 is placed on a horizontal ground. Also, the scale 33b indicates the value of the tilt angle α, with the direction in which the tillage depth D increases (clockwise direction in FIG. 6) being "+", and the direction in which the tillage depth D decreases (counterclockwise direction in FIG. 6) being "-".

[0062] The auxiliary line 33c indicates the direction of the line 33d when the tilt angle α is 0.

[0063] The line 33d indicates the tilt angle α of the vehicle body detected by the tilt sensor 27b. The line 33d is displayed across the illustration 33a, pointing to the left and right scales 33b. The line 33d is displayed so as to tilt at an angle corresponding to the detected tilt angle α.

[0064] The display of the illustration 33a and the line 33d of the first tilt angle display unit 33 configured as described above is updated by the control means 27d. Specifically, the control means 27d acquires (detects) the tilt angle α of the vehicle body every predetermined short time (for example, 0.1 second to 1 second), and changes the direction of the line 33d so as to indicate the acquired tilt angle α. Also, the control means 27d tilts and displays the illustration 33a in accordance with the tilt of the line 33d. In this way, the control means 27d can display the tilt angle α of the vehicle body in real time.

[0065] The second tilt angle display unit 34 is a part that displays the tilt angle β of the vehicle body with respect to the left - right direction detected by the tilt sensor 27b. The second tilt angle display unit 34 has an illustration 34a, a scale 34b, an auxiliary line 34c, and a line 34d displayed thereon.

[0066] Illustration 34a is an image schematically showing the rotary 18 as viewed from the back. By appropriately tilting and displaying this image, the user can intuitively understand the state in which the walking type management machine 10 is tilted in the left - right direction.

[0067] The scale 34b indicates the value of the tilt angle β. The scale 34b is displayed on the left and right sides of the illustration 34a respectively. The scale 34b in FIG. 6 sets the tilt angle β of the vehicle body in the state where the walking type management machine 10 is placed on a horizontal ground to 0. Also, the scale 34b indicates the value of the tilt angle β, with the direction of tilting downward to the right being "+", and the direction of tilting downward to the left being "-".

[0068] The auxiliary line 34c indicates the direction of the line 34d when the tilt angle β is 0.

[0069] The line 34d indicates the tilt angle β of the vehicle body detected by the tilt sensor 27b. The line 34d is displayed across the illustration 34a so as to point to the left and right scales 34b. The line 34d is displayed at an angle tilted according to the detected tilt angle β.

[0070] The display of the illustration 34a and the line 34d of the second tilt angle display unit 34 configured as described above is updated in real - time by the control means 27d, similar to the case of the first tilt angle display unit 33.

[0071] By visually recognizing the display screen 30 as described above, the user can easily grasp the tilt angles α and β of the vehicle body. For example, when the vehicle body tilts in the front-rear direction during tilling work, the tilt angle α detected by the tilt sensor 27b is reflected in the first tilt angle display section 33. Therefore, the user can easily grasp the tilt angle α of the vehicle body by visually recognizing the first tilt angle display section 33 (the value of the scale 33b indicated by the line 33d). As a result, the user can easily adjust the tilt angle α, and thus can easily adjust the tilling depth D. In this way, the display mechanism 26 can improve the convenience of operating the walking type management machine 10.

[0072] Furthermore, the target display section 32 of the display screen 30 displays a tilt angle α that results in a tilling depth D suitable for cultivating the crop. The user can cultivate the field A at an appropriate tilling depth D according to the crop by adjusting the tilt angle α of the vehicle body by moving the handle 24 up and down so that the tilt angle α displayed in the first tilt angle display section 33 becomes the value displayed in the target display section 32.

[0073] Also, the user can easily grasp the tilt angle β in the left-right direction of the vehicle body by visually recognizing the second tilt angle display section 34. Also, if the posture of the walking type management machine 10 is adjusted so that the angle displayed in the second tilt angle display section 34 becomes a desired angle (for example, 0°), tilling work can be performed in a stable posture.

[0074] Also, the user can select an arbitrary crop from a plurality of crops by touching and operating the selection section 31. As a result, the user can perform appropriate tilling work for each crop.

[0075] As described above, the display mechanism 26 of the walking type management machine 10 (management machine) according to the present embodiment includes an inclination sensor 27b (inclination angle detection unit) that detects the inclination angles α and β of the vehicle body of the walking type management machine 10 including the rotary 18 and the handle 24, and a touch panel 27c (display unit) that displays information (angle information) regarding the inclination angles α and β of the vehicle body detected by the inclination sensor 27b.

[0076] By configuring in this way, the convenience of driving the walking type management machine 10 can be improved. That is, the user can easily grasp the posture (inclination angles α and β) of the walking type management machine 10 by checking the information regarding the inclination angles α and β of the walking type management machine 10 displayed on the touch panel 27c, and can easily perform the driving of the walking type management machine 10 (particularly, the adjustment of the tillage depth D).

[0077] Further, the information includes the inclination angles α and β of the vehicle body.

[0078] By configuring in this way, the convenience of driving the walking type management machine 10 can be improved. That is, by grasping the specific values of the inclination angles α and β, more precise driving of the walking type management machine 10 becomes possible.

[0079] Further, the information includes a standard (inclination angle displayed on the target display unit 32) indicating whether the inclination angle α of the vehicle body is suitable for a predetermined operation.

[0080] By configuring in this way, the convenience of driving the walking type management machine 10 can be improved. That is, the user can easily adjust the inclination angle α of the walking type management machine 10 with reference to the displayed standard (target display unit 32).

[0081] Further, the walking type management machine 10 according to the present embodiment includes the display mechanism 26.

[0082] By configuring in this way, the convenience of driving the walking type management machine 10 can be improved.

[0083] Further, the walking-type management machine 10 further includes tires 12.

[0084] By configuring in this way, it becomes easier to define the inclination angle α (tillage depth D) starting from the contact point between the tire 12 and the field A. By adjusting the posture of the vehicle body based on the inclination angle α defined in this way as a reference, it becomes possible to easily control the tillage depth D.

[0085] Note that the inclination sensor 27b according to the present embodiment is one form of implementation of the inclination angle detection unit according to the present invention. Further, the touch panel 27c according to the present embodiment is one form of implementation of the display unit according to the present invention.

[0086] As described above, the first embodiment of the present invention has been described. However, the present invention is not limited to the above configuration, and various modifications are possible within the scope of the invention described in the claims.

[0087] For example, in the present embodiment, an example in which the attachment portion 28 is provided on the lateral frame portion 24c of the handle 24 is shown. However, it is not limited to such a mode. For example, the attachment portion 28 may be provided on the side portion 24a, or may be provided on the fuel tank 14, the bonnet 15, or the like. That is, as long as the user can visually recognize the touch panel 27c, the position where the attachment portion 28 is provided can be arbitrarily changed.

[0088] Also, it is possible to adopt a configuration in which the terminal 27 notifies the user about driving (particularly, adjustment of the tilt angles α and β). For example, the control means 27d calculates the difference between the detected tilt angle α and the tilt angle displayed on the target display unit 32, and when the difference exceeds a predetermined threshold, a configuration can be adopted in which a notification is given to prompt adjustment of the tilt angle α. As a method of notification in this case, for example, a predetermined message (such as "Please raise the vehicle body slightly forward") is displayed on the touch panel 27c, or the message is output as voice from the speaker 27a. There is also a method of notification by changing sounds and tones such as warning sounds and notification sounds. By adjusting the tilt angle α according to this notification, the user can easily adjust the tillage depth D.

[0089] Thus, the information includes a notification that prompts the user to adjust the tilt angle α of the vehicle body so that the tilt angle α of the vehicle body becomes a tilt angle suitable for a predetermined operation.

[0090] By configuring in this way, the convenience of driving the walking-type management machine 10 can be improved. That is, the user can easily adjust the tilt angle α of the walking-type management machine 10 to a tilt angle suitable for a predetermined operation by adjusting the tilt angle α of the walking-type management machine 10 according to the notification.

[0091] Also, FIG. 6 shows an example of displaying the tilt angles α and β on the touch panel 27c, but the angle information displayed on the touch panel 27c is not limited to the tilt angles α and β.

[0092] For example, in the first modification shown in Fig. 7(a), a screen is shown in which the tillage depth D is displayed instead of the tilt angle α. Specifically, in the target display unit 42 of the first modification, the tillage depth D (see Fig. 5(c)) suitable for cultivating the crop displayed in the selection unit 31 is displayed. Further, the value of the tillage depth D is displayed on the scale 43b. The control means 27d calculates the tillage depth D of the walking type management machine 10 from the detected tilt angle α, and changes the direction of the line 33d according to this tillage depth D. The user can grasp the tillage depth D by visually recognizing the scale 43b indicated by the line 33d.

[0093] As described above, the information includes a value obtained by converting the tilt angle α of the vehicle body into the working depth (tillage depth D) by the working machine mounted on the walking type management machine 10.

[0094] By configuring in this way, the convenience of driving the walking type management machine 10 can be improved. That is, the user can easily grasp the tillage depth D by the rotary tiller 18, and can easily drive the walking type management machine 10 (particularly, adjustment of the tillage depth D).

[0095] Also, for example, in the second modification shown in Fig. 7(b), a screen is shown in which the type of crop is displayed instead of the tilt angle α. Specifically, in the second modification, the name of the crop is appropriately displayed on the scale 53b indicating the tillage depth D (tilt angle α) suitable for that crop. The control means 27d changes the direction of the line 33d according to the detected tilt angle α. The user can intuitively adjust the tillage depth D by adjusting the tilt angle α of the walking type management machine 10 so that the line 33d points to the scale 53b showing the desired crop.

[0096] Further, the display screen 30 shown in Figs. 6 and 7 is an example, and the display methods of the tilt angles α and β, the tillage depth D, etc. are not limited to this. For example, the illustrations shown in Fig. 6 etc. are an example and can be arbitrarily changed. Also, instead of using illustrations, it is also possible to display only specific numerical values such as the tilt angles α and β and the tillage depth D.

[0097] Also, the control means 27d is configured to detect the tilt angles α and β using a gyro sensor (tilt sensor 27b), but other types of sensors (e.g., an acceleration sensor) may be used to detect the tilt angles α and β.

[0098] Further, the control means 27d may be configured to be able to arbitrarily adjust (zero point adjustment) the value that serves as a reference for the detection of the tilt angles α and β by the tilt sensor 27b. For example, in this embodiment, the tilt angles α and β are detected based on the state where the walking type management machine 10 is placed on a horizontal ground. However, when the farm field A itself is inclined as a whole, it is also possible to detect the tilt angles α and β based on the inclination of the farm field A. As a result, the tillage depth D can be accurately calculated based on the tilt angles α and β. Also, by performing zero point adjustment as appropriate, it is possible to suppress deterioration in the detection accuracy of the tilt angles α and β by the tilt sensor 27b.

[0099] In this embodiment, an example is shown in which a terminal 27 in which a tilt sensor 27b for detecting the tilt angles α and β of the vehicle body and a touch panel 27c for displaying information regarding the tilt angles α and β are integrated is used. However, the present invention is not limited to this. For example, it is also possible to separately provide the tilt sensor 27b and the touch panel 27c (display unit).

[0100] In this embodiment, as the names of the crops, classifications of vegetables ("root vegetables", "leafy and stem vegetables", "fruit vegetables") are exemplified. However, the present invention is not limited to this, and any name can be used. For example, not limited to the above classifications, it is also possible to use classifications classified based on any criteria, or more specific vegetable variety names, etc. Also, not limited to vegetables, it is possible to use the names of various other crops. Furthermore, instead of the names of the crops, it is also possible to use the names of the operations (tillage operation, mulching operation, etc.).

[0101] Next, with reference to FIGS. 8 to 10, the walking type management machine 10 according to the second embodiment will be described.

[0102] The walking-type management machine 10 according to the second embodiment is different from the display mechanism 26 according to the first embodiment in the configuration of the display mechanism 126.

[0103] The display mechanism 126 is for displaying the tilt angle α with respect to the front-rear direction of the vehicle body. As shown in FIGS. 8 and 9, the display mechanism 126 includes a level 127 and a mounting portion 128.

[0104] The level 127 is for displaying the tilt angle α. The level 127 is provided on the steering wheel 24 via a mounting portion 128 described later. The level 127 includes a case 127a, a bubble tube 127b, and a label 127c.

[0105] The case 127a forms the outer shape of the level 127. The case 127a is formed in a substantially rectangular parallelepiped shape capable of accommodating the bubble tube 127b.

[0106] The bubble tube 127b is a transparent container filled with a liquid leaving a bubble. The bubble tube 127b is housed in the case 127a and provided so that the bubble can be visually recognized from above. A reference line L127 for indicating the magnitude of the inclination (tilt angle α) is marked on the bubble tube 127b.

[0107] The label 127c is for indicating the tilt angle α suitable for each crop. Information for identifying the crop (the name of the crop type) is described on the label 127c. A plurality of labels 127c are provided and are appropriately attached so as to point to the reference line L127 indicating the tilt angle α suitable for each crop.

[0108] The mounting portion 128 is capable of mounting the level 127. The mounting portion 128 is composed of a pair of front and rear plate members that can be fitted to the cross-member 124c and can be detachably attached to the cross-member 24c. In the present embodiment, an example in which the mounting portion 128 is attached to the central portion in the left-right direction of the cross-member 24c of the steering wheel 24 is shown.

[0109] The level 127 of the display mechanism 126 configured as described above is provided so as to be parallel (horizontal) with respect to the front-rear direction in a state where the walking-type management machine 10 is placed on a horizontal ground (a state where the tires 12 and the tilling claws 18a are in contact with the horizontal ground). At this time, the air bubble of the level 127 is located between the two inner front-rear reference lines L127 (see Fig. 9(a)).

[0110] When performing tilling work with the walking-type management machine 10, the tilling claws 18a enter the field A, and the vehicle body of the walking-type management machine 10 inclines with respect to the front-rear direction. When the vehicle body inclines with respect to the front-rear direction, the orientation of the level 127 changes according to the inclination angle α, and as shown in Fig. 10, the air bubble in the air bubble tube 127b moves.

[0111] Therefore, by visually recognizing the level 127, the user can easily grasp the inclination angle α of the vehicle body. Thereby, the user can adjust the inclination angle α, and thus can easily adjust the tilling depth D. In this way, the display mechanism 126 can improve the convenience of operating the walking-type management machine 10. Thus, in the second embodiment, the level 127 also serves as an inclination angle detection unit that detects the inclination angle α of the vehicle body and a display unit that displays information regarding the inclination angle.

[0112] Also, as described above, the label 127c indicates the inclination angle α (tilling depth D) suitable for cultivating crops. Therefore, by visually recognizing the air bubble tube 127b and the label 127c, the user can easily grasp whether tilling work is being performed at an inclination angle α (tilling depth D) suitable for the crops. Also, if the inclination angle α of the vehicle body is adjusted so that the position indicated by the label 127c coincides with the position of the air bubble, the field A can be tilled at a tilling depth D suitable for the crops.

[0113] The second embodiment of the present invention has been described above. However, the present invention is not limited to the above configuration, and various modifications are possible within the scope of the invention described in the claims.

[0114] For example, although the level 127 is configured to display the tilt angle α in the longitudinal direction of the vehicle body, it is not limited thereto, and the tilt angle β in the lateral direction (see FIG. 4) may be displayed. In this case, by installing the level 127 such that the bubble tube 127b faces the lateral direction, the tilt angle β can be displayed. Further, by providing two levels 127 capable of respectively displaying the tilts in the longitudinal and lateral directions, the tilt angles α and β in the longitudinal and lateral directions of the vehicle body may be respectively displayed.

[0115] Further, the level 127 is not limited to the one exemplified in the second embodiment, and various types can be adopted. For example, a digital level or a level (round level) capable of detecting a 360-degree tilt not limited to the longitudinal and lateral directions can be used.

[0116] Also, an example in which a label 127c with the name of the crop is provided on the level 127 has been shown, but the present invention is not limited thereto. For example, by providing a label 127c with the numerical values of the tilt angle and the tillage depth on the level 127, the user can grasp the specific values of the tilt angle α of the vehicle body and the tillage depth D.

[0117] In each of the above embodiments, the walking type management machine 10 equipped with the tire 12 has been described as an example, but the present invention is not limited thereto, and it can also be applied to a walking type management machine 10 not equipped with the tire 12. Further, regardless of whether the tire 12 is provided or not, around the contact point between the resistance bar 19 and the field A, the user can cultivate the field A at a desired tillage depth D (for example, a tillage depth D suitable for the crop cultivated in the field A) by moving the handle 24 up and down to adjust the tilt angle α of the walking type management machine 10. However, in the case of the walking type management machine 10 equipped with the tire 12, since the walking type management machine 10 tilts according to the tillage depth D around the tire 12 that contacts the surface (ground) of the field A, the correlation between the tilt angle α and the tillage depth D becomes high, and thus it becomes easier to grasp the tillage depth D from the tilt angle α. Therefore, the present invention is preferably applied to the walking type management machine 10 equipped with the tire 12.

[0118] In addition, in each of the above-described embodiments, the walking-type management machine 10 equipped with the rotary 18 has been described as an example. However, the display mechanisms 26 and 126 can be applied not only to the rotary 18 but also to the walking-type management machine 10 equipped with various other working machines. For example, by applying the display mechanism 26 to the walking-type management machine 10 equipped with a ridging machine or a leveling board, the user can easily grasp whether the tilt angles α and β of the vehicle body of the walking-type management machine 10 are appropriate and constant, etc., and the driving convenience can be improved.

[0119] In addition, in each of the above-described embodiments, an example of displaying the tilt angle α and the tillage depth D of the walking-type management machine 10 using the display mechanisms 26 and 126 has been shown. However, the method of displaying the tilt angle α and the like is not limited to this. For example, by describing indications (scales, numbers, symbols, etc.) serving as references for the tilt angle α and the tillage depth D on the side surface of the rotary 18 or the resistance bar 19 and confirming the positional relationship between the indication and the ground, etc., it is also possible to grasp the tilt angle α and the like. Further, it is also possible to hang a pendulum on the walking-type management machine 10 (vehicle body) and display the tilt angle α and the like from the inclination between the pendulum and the vehicle body.
