[0039] Hereinafter, an embodiment of the passenger management machine 1 of the present invention will be described.

[0040] Figure 1 It is a side view showing one embodiment of the passenger management machine 1.

[0041] like Figure 1 As shown, the riding cultivating machine 1 includes a traveling vehicle 1A and a working machine 1B mounted on the traveling vehicle 1A. The riding cultivating machine 1 allows an operator to ride on the traveling vehicle 1A and perform work (agricultural work) on a field using the working machine 1B.

[0042] like Figure 1 to Figure 4As shown, the traveling vehicle 1A includes a vehicle body 2 and a traveling device 3 that supports the vehicle body 2 so as to be able to travel.

[0043] In this embodiment, the front side ( Figure 1 The arrow A1 direction) is set as the front, and the rear side ( Figure 1 Arrow A2 direction) is set to the rear, and the left side ( Figure 2 arrow B1 direction) to the left, and the right side ( Figure 2 The arrow B2 direction) is set to the right for explanation. Figure 1 The horizontal direction perpendicular to the arrow A3 direction is set as the vehicle width direction (refer to Figure 2 In addition, the direction away from the vehicle body 2 in the vehicle width direction B3 is called the vehicle width direction outer side, and the direction close to the vehicle body 2 in the vehicle width direction is called the vehicle width direction inner side.

[0044] like Figure 1 As shown, the vehicle body 2 includes a prime mover 5 , a clutch housing 6 , a connecting frame 7 , and a transmission 8 .

[0045] The prime mover 5 is, for example, an engine, more specifically, a diesel engine. The clutch housing 6 is connected to the rear of the prime mover 5. The clutch housing 6 accommodates a flywheel that reduces and stabilizes the change in the rotational force of the prime mover 5 and a clutch that can transmit the power of the prime mover 5 transmitted via the flywheel in an on-off manner. The connecting frame 7 connects the clutch housing 6 to the transmission 8. The transmission 8 accommodates a speed change device that changes the speed of the power transmitted via the clutch. The prime mover 5, the clutch housing 6, the connecting frame 7, and the transmission 8 are integrally connected to form a vehicle body frame 9.

[0046] The travel device 3 includes a front wheel 3F and a rear wheel 3R. Figure 2 As shown, the front wheel 3F includes a left front wheel 3FL arranged on the left side of the vehicle body 2 and a right front wheel 3FR arranged on the right side of the vehicle body 2. The rear wheel 3R includes a left rear wheel 3RL arranged on the left side of the vehicle body 2 and a right rear wheel 3RR arranged on the right side of the vehicle body 2.

[0047] like Figure 1 , Figure 2 As shown, the vehicle body 2 has a front axle frame 10 fixed to the lower portion of the prime mover 5. The front axle frame 10 supports a front axle box 11. The front axle box 11 accommodates a front axle 12 connected to the front wheel 3F.

[0048] like Figure 2 , Figure 6As shown, the front axle frame 10 includes a left frame 10L, a right frame 10R, a front frame 10F, and an intermediate frame 10M. The left frame 10L is fixed to the lower left portion of the prime mover 5. The right frame 10R is fixed to the lower right portion of the prime mover 5. The left frame 10L and the right frame 10R extend in parallel to each other in the front-to-back direction. The front frame 10F connects the front end of the left frame 10L with the front end of the right frame 10R. The intermediate frame 10M connects the middle portion of the left frame 10L in the front-to-back direction with the middle portion of the right frame 10R in the front-to-back direction. A counterweight 27 is installed at the front of the front frame 10F.

[0049] The driver's seat 4 is mounted on the rear part of the vehicle body 2. The driver's seat 4 is provided between the left rear wheel 3RL and the right rear wheel 3RR. A steering wheel 13 for steering the steering wheel (the front wheel 3F in this embodiment) is provided in front of the driver's seat 4. A mounting device 14 for detachably mounting the working machine 1B is provided at the rear part of the vehicle body 2. The mounting device 14 is composed of a three-point linkage mechanism, and has an upper link 14A and two lower links 14B. The mounting device 14 enables the working machine 1B to be raised and lowered relative to the vehicle body 2. For example, a transplanter for vegetables (onions, etc.) can be installed on the mounting device 14 as the working machine 1B. However, the working machine 1B is not limited to a transplanter as long as it is a device for working on the field. In addition, the working machine 1B can also be mounted on the front part of the vehicle body 2.

[0050] A hood 15 is provided in front of the driver's seat 4. The hood 15 is mounted on the vehicle body frame 9 so as to cover the prime mover 5. The hood 15 can be opened upward. Specifically, when the hood 15 is opened, the front portion is raised with the rear portion as a fulcrum (see Figure 1 virtual line).

[0051] like Figure 2 As shown, a step 16 is provided on the side and in front (diagonally in front and on the side) of the driver's seat 4. The step 16 includes a first step 16L and a second step 16R. The first step 16L is provided on one side (left side) of the driver's seat 4 in the vehicle width direction. The second step 16R is provided on the other side (right side) of the driver's seat 4 in the vehicle width direction.

[0052] A first rising portion 17L is provided in front of the first pedal 16L. The first rising portion 17L is located in the left front of the driver's seat 4. Figure 1 , Figure 4 The first pedal 16L is provided with a pedal shaft of a clutch pedal 18. A foot stepping portion 19 for an operator (driver) to step on when getting on or off the vehicle is provided on the left side of the first pedal 16L.

[0053] A second rising portion 17R is provided in front of the second pedal 16R. The second rising portion 17R is located in front of the right side of the driver's seat 4 and rises obliquely toward the upper front. The pedal shafts of the brake pedals 20L and 20R pass through the second rising portion 17R.

[0054] like Figure 5 As shown, the traveling vehicle 1A has a steering device 21. The steering device 21 has a steering wheel 13, a steering shaft 22 that rotates with the rotation of the steering wheel 13, and an auxiliary mechanism (power steering mechanism) 23 that assists the steering of the steering wheel 13. The auxiliary mechanism 23 includes a hydraulic pump P1, a control valve 24 supplied with working oil discharged from the hydraulic pump P1, and a steering cylinder 25 that works through the control valve 24. The control valve 24 is an electromagnetic valve that works based on a control signal, for example, a 3-position switching valve that can be switched by the movement of a slide valve or the like. In addition, the control valve 24 can also be switched by the steering of the steering shaft 22. The steering cylinder 25 is connected to an arm (knuckle arm) 26 that changes the direction of the front wheels 3FL and 3FR.

[0055] When the steering wheel 13 is operated, the switching position and the opening of the control valve 24 are switched according to the operation of the steering wheel 13, and the piston rod of the steering cylinder 25 moves leftward or rightward according to the switching position and the opening of the control valve 24. Thus, the steering direction (steering direction) of the front wheel 3F can be changed. However, the configuration of the steering device 21 is not limited to the above configuration.

[0056] like Figure 1 to Figure 4 As shown in FIG. 1 , the traveling vehicle 1A includes a position detection device 30 for detecting the position (traveling position) of the traveling vehicle 1A (vehicle body 2 ). The position detection device 30 is attached to a support body 40 described later and supported by the vehicle body 2 .

[0057] The position detection device 30 receives a signal from a positioning satellite and detects the position of the vehicle body 2 based on the received signal. That is, the position detection device 30 is a device that detects the position information of the vehicle body 2 using a satellite positioning system (GNSS: Global Navigation Satellite System). As a satellite positioning system, for example, GPS (Global Positioning System) can be used. As a positioning method using a positioning satellite system, for example, a positioning method using an RTK (Real Time Kinematic) method can be used.

[0058] The position detection device 30 is a device that detects its own position (including positioning information of latitude and longitude) through a satellite positioning system. That is, the position detection device 30 receives signals (position of the positioning satellite, transmission time, correction information, etc.) sent from the positioning satellite, and detects the position (latitude, longitude) based on the received signal. The position detection device 30 preferably detects the position corrected based on the correction signal from the base station (reference station) as its own position (latitude, longitude), and the base station can receive signals from the positioning satellite. In addition, the position detection device 30 may also have an inertial measurement device such as a gyro sensor and an acceleration sensor, and detects the position corrected by the inertial measurement device as its own position.

[0059] like Figure 5 As shown, the traveling vehicle 1A includes a control device 31 .

[0060] The control device 31 is connected to a position detection device 30, a travel detection device 32 of a travel system, and an operation detection device 33 of an operation system. Therefore, the control device 31 can obtain the position detected by the position detection device 30, the detection value detected by the travel detection device 32, and the detection value detected by the operation detection device 33. The travel detection device 32 is, for example, a crank sensor, a cam sensor, an engine rotation sensor, an accelerator sensor, a vehicle speed sensor, a steering angle sensor, etc. The operation detection device 33 is, for example, a lever detection sensor, a PTO rotation sensor, etc.

[0061] The control device 31 controls the travel system and the working system in the travel vehicle 1A. For example, the control device 31 controls the rotation speed of the prime mover 5 (engine), the vehicle speed, the steering angle of the steering device 21, etc. based on the detection value detected by the travel detection device 32. In addition, the control device 31 controls the lifting and lowering of the lifting device for lifting the working machine installed on the travel vehicle 1A, the PTO rotation speed, etc. based on the detection value detected by the working detection device 33.

[0062] The control device 31 includes a steering control unit 34. The steering control unit 34 is composed of electric and electronic components provided in the control device 31, a program incorporated in the control device 31, and the like.

[0063] The steering control unit 34 (control device 31) can automatically control (automatic steering control) the steering of the traveling vehicle 1A based on the set planned traveling route (planned traveling path). Figure 5As shown, the traveling vehicle 1A has, for example, a switch (command switch) 35 for enabling or disabling the automatic steering control. The command switch 35 is connected to the control device 31. The command switch 35 is a switch that can be switched to ON / OFF. When it is ON, the automatic steering control is enabled, and when it is OFF, the automatic steering control is disabled. In addition, the command switch 35 is provided near the driver's seat 4 and can be operated by an operator (driver).

[0064] When the automatic steering control is effective, the steering control unit 34 sets the switching position and the opening degree of the control valve 24 so that at least the running position (the position detected by the position detection device 30) of the running vehicle 1A (the vehicle body 2) matches the planned running route. In other words, when the automatic steering control is effective, the control device 31 sets the moving direction and the moving amount (the steering direction and the steering angle of the front wheel 3F) of the piston rod of the steering cylinder 25 so that the running position of the running vehicle 1A matches the planned running route.

[0065] Specifically, when the automatic steering control is effective, the steering control unit 34 compares the driving position of the driving vehicle 1A (vehicle body 2) detected by the position detection device 30 with the position indicated by the scheduled driving route (scheduled driving position), and when the driving position coincides with the scheduled driving position, the steering angle and steering direction of the steering wheel 13 in the steering device 21 (the steering angle and steering direction of the front wheels 3F) are not changed but maintained (the opening and switching position of the control valve 24 are not changed but maintained). In addition, when the driving position does not coincide with the scheduled driving position, the steering control unit 34 changes the steering angle and / or steering direction of the steering wheel 13 in the steering device 21 (changes the opening and / or switching position of the control valve 24) so ​​that the deviation (offset) between the driving position and the scheduled driving position is zero.

[0066] When the automatic steering control is invalid, the steering control unit 34 sets the steering direction and steering angle of the front wheels 3F, the vehicle speed, etc. based on the operator's operation (operation of the steering wheel 13 by the operator, operation of the accelerator by the operator, etc.). That is, the operator can manually change the direction of the traveling vehicle 1A (vehicle body 2) through the steering control unit 34.

[0067] like Figure 5 As shown, the traveling vehicle 1A includes a display device 36. The display device 36 is disposed, for example, near the driver's seat 4. The operator can visually check and operate the display device 36 while sitting in the driver's seat 4. The display device 36 is a device capable of displaying various information, and includes a display unit (screen) 36a composed of a liquid crystal panel, a touch panel, or the like.

[0068] The display device 36 includes a baseline setting unit 36b and a driving setting unit 36c. The baseline setting unit 36b and the driving setting unit 36c are composed of electrical and electronic components provided in the display device 36, programs incorporated into the display device 36, etc. The baseline setting unit 36b sets a baseline that serves as a reference during driving. The driving setting unit 36c performs settings related to the driving of the driving vehicle 1A. The driving setting unit 36c sets a planned driving route of the driving vehicle 1A (vehicle body 2) based on the baseline set by manual driving. The display unit 36a (display device 36) can display the planned driving route.

[0069] The display device 36 includes a storage unit 36d. The storage unit 36d is a non-volatile memory or the like. When the reference line is set by making the vehicle 1A travel straight, the starting position and the ending position of the reference line are stored in the storage unit 36d. Specifically, when the vehicle 1A is located at the work start position, the path setting button 36e (see FIG. 36A ) displayed on the display device 32 is pressed. Figure 5 ), the starting point is stored (registered) in the storage unit 36d as the position information obtained by the satellite positioning system. Next, the driving vehicle 1A is manually operated to travel straight, and the work is performed using the work machine, and the route setting button 36e is pressed at the end position of the work at the end of the field. Then, the end point is stored (registered) in the storage unit 36d as the position information, and the reference line of the straight line connecting the starting point and the end point is stored (registered) in the storage unit 36d. The planned driving route is set to any number in parallel with the reference line according to the area of ​​the field, etc.

[0070] The above-described traveling vehicle 1A can travel along the planned traveling route by automatically steering the vehicle body 3 based on the planned traveling route through the automatic steering control of the steering control unit 28 .

[0071] Next, the support body 40 that supports the position detection device 30 will be described.

[0072] like Figure 1 to Figure 3 As shown, the support body 40 supports the position detection device 30 above the hood 15. By supporting the position detection device 30 above the hood 15, it is difficult for the signal from the positioning satellite to be blocked, and the receiving sensitivity can be improved. The position detection device 30 is arranged above the hood 15 and is more rearward than the front axle 12. In addition, the position detection device 30 is arranged at a rearward position than the center of the hood 15 in the front-to-back direction (close to the rear of the hood 30). Thus, as Figure 1 As shown by the virtual line, when the hood 15 is opened, interference between the hood 15 and the position detection device 30 can be avoided.

[0073] like Figure 3 , Figure 7 , Figure 8As shown, the support body 40 has a pair of pillars and a connecting portion 40C. The pair of pillars includes a first pillar 40L and a second pillar 40R. The first pillar 40L, the second pillar 40R, and the connecting portion 40C constituting the support body 40 are formed of a hollow tube (circular tube).

[0074] The work vehicle 2 does not include a rollover protection system (ROPS) for protecting an operator sitting on the driver's seat 4 from overturning, and the support body 40 does not correspond to the rollover protection system.

[0075] The first support column 40L is erected on one side (left side) of the vehicle body 2 in the vehicle width direction. The second support column 40R is erected on the other side (right side) of the vehicle body 2 in the vehicle width direction. The first support column 40L and the second support column 40R are erected in front of the driver's seat 4 and in the rear of the front axle 12. Figure 1 In the example shown, the first support 40L and the second support 40R extend vertically upward from the vehicle body 2 , but may be inclined forward or backward. The connecting portion 40C extends in the vehicle width direction and connects the upper ends of the first support 40L and the second support 40R above the hood 15 .

[0076] The position detection device 30 is installed on the connection portion 40C. The position detection device 30 is installed on the upper part of the connection portion 30C. Figure 2 As shown in FIG. 1 , the position detection device 30 and the connection portion 40C are arranged at a position where they overlap in a plan view.

[0077] like Figure 7 , Figure 8 As shown, a mounting portion 41 for mounting the position detection device 30 is provided at the upper portion of the connecting portion 40C. The mounting portion 41 is arranged at the center of the connecting portion 40C in the vehicle width direction. The mounting portion 41 has a pair of support plates 41L, 41R and a loading plate 41U. The position detection device 30 is mounted on the upper surface of the loading plate 41U by means of bolts or the like. The support plate 41L is fixed to the left portion of the lower surface of the loading plate 41U by welding or the like. The support plate 41R is fixed to the right portion of the lower surface of the loading plate 41U by welding or the like. The support plates 41L, 41R are arranged parallel to each other with a gap in the vehicle width direction. The support plates 41L, 41R are fixed to the upper portion of the connecting portion 40C by welding or the like. Specifically, the support plates 41L, 41R have arc-shaped notches 41a (refer to Figure 1 ), the notch 41a is welded along the outer peripheral surface of the connecting portion 40C.

[0078] The position detection device 30 includes a device body 30a and an antenna 30b. The height of the connection portion 40C is set so that the height of the position detection device 30 (specifically, the height of the upper surface of the device body 30a) is 2 m or less from the ground.

[0079] like Figure 1As shown in FIG. 1 , the height of the position detection device 30 is higher than the height of the upper end of the driver's seat 4 (the upper end of the backrest), and is higher than the height of the sight line of the operator sitting on the driver's seat 4. Thus, the operator's field of vision in front is not blocked by the position detection device 30. In addition, the height of the position detection device 30 is higher than the height of the upper end of the steering wheel 13.

[0080] The upper and lower parts of the support body 40 are formed of independent parts. Specifically, the support body 40 has a lower part 401 and an upper part 402, and is formed by combining the lower part 401 and the upper part 402.

[0081] The lower portion 401 is composed of the lower portion of the first support 40L and the lower portion of the second support 40R. The lower portion 401 includes a tube that constitutes the lower portion of the first support 40L and a tube that constitutes the lower portion of the second support 40R. The upper portion 402 includes a connecting portion 40C, an upper portion of the first support 40L, and an upper portion of the second support 40R. The upper portion 402 is composed of a single tube that is bent into a gate shape (inverted U shape). That is, the connecting portion 40C, the upper portion of the first support 40L, and the upper portion of the second support 40R that constitute the upper portion 402 are composed of a single tube.

[0082] The lower portion 401 is mounted on the vehicle body 2. The upper portion 402 is detachably mounted on the lower portion 401. Figure 7 As shown, a small diameter portion 402a having an outer diameter smaller than the inner diameter of the lower portion 401 is formed at the lower portion of the upper portion 402. The small diameter portion 402a of the upper portion 402 is inserted from the upper end of the lower portion 401 and fixed with a fastener (bolt, nut) 51, so that the upper portion 402 can be detachably mounted on the lower portion 401.

[0083] like Figure 6 , Figure 8 , Fig. 9 As shown, the first pillar 40L has a first longitudinal portion 40La and a first transverse portion 40Lb. The first longitudinal portion 40La extends in the up-down direction. The first transverse portion 40Lb extends from the lower end of the first longitudinal portion 40La toward the inner side (right side) in the vehicle width direction. The first transverse portion 40Lb is provided at the lower end of the first pillar 40L. In other words, the first transverse portion 40Lb extending toward the inner side (right side) in the vehicle width direction is provided at the lower end of the first pillar 40L.

[0084] The second support column 40R has a second longitudinal portion 40Ra and a second transverse portion 40Rb. The second longitudinal portion 40Ra extends in the up-down direction. The second transverse portion 40Rb extends from the lower end of the second longitudinal portion 40Ra toward the inner side (left side) in the vehicle width direction. The second transverse portion 40Rb is provided at the lower end of the second support column 40R. In other words, the second transverse portion 40Rb extending toward the inner side (left side) in the vehicle width direction is provided at the lower end of the second support column 40R.

[0085] like Figure 2 , Figure 4 , Figure 6 , Fig.11 As shown, the lower portion (lower portion 401) of the support body 40 is mounted to the vehicle body 2 (specifically, the front axle frame 10) via a first bracket 45 and a second bracket 46. The first bracket 45 is mounted on one side (left side) of the vehicle body 2 in the vehicle width direction. The second bracket 46 is mounted on the other side (right side) of the vehicle body 2 in the vehicle width direction.

[0086] The first bracket 45 protrudes outward in the vehicle width direction (toward the left) from the left portion of the front axle frame 10. The second bracket 46 protrudes outward in the vehicle width direction (toward the right) from the right portion of the front axle frame 10.

[0087] like Figure 2 As shown, the first bracket 45 and the second bracket 46 are arranged behind the front axle 12. The first bracket 45 and the second bracket 46 are covered with the hood 15 above. In other words, the first bracket 45 and the second bracket 46 are entirely overlapped with the hood 15 in a plan view.

[0088] like Figure 6 to Figure 11 As shown, the first bracket 45 has a first lower plate 45a, a first front plate 45b, a first rear plate 45c, and a first side plate 45d. Fig. 9 As shown, the first lower plate 45a has a first horizontal portion 45a1 and a first vertical portion 45a2. The first horizontal portion 45a1 is arranged in a manner that one surface faces upward and the other surface faces downward. The first vertical portion 45a2 is bent from the left end of the first horizontal portion 45a1 and extends downward. The first front plate 45b is connected to the front edge of the first lower plate 45a. The first rear plate 45c is connected to the rear edge of the first lower plate 45a. The first front plate 45b and the first rear plate 45c are arranged parallel to each other with a gap in the front-to-back direction. The first side plate 45d is arranged in a manner that one surface faces left and the other surface faces right. One surface of the first side plate 45d is connected to the right ends of the first front plate 45b, the first rear plate 45c, and the first lower plate 45a.

[0089] The second bracket 46 has a second lower plate 46a, a second front plate 46b, a second rear plate 46c, and a second side plate 46d. Fig. 9As shown, the second lower plate 46a has a second horizontal portion 46a1 and a second vertical portion 46a2. The second horizontal portion 46a1 is configured in a manner that one surface faces upward and the other surface faces downward. The second vertical portion 46a2 is bent from the right end of the second horizontal portion 46a1 and extends downward. The second front plate 46b is connected to the front edge of the second lower plate 46a. The second rear plate 46c is connected to the rear edge of the second lower plate 46a. The second front plate 46b and the second rear plate 46c are configured parallel to each other with a gap in the front-to-back direction. The second side plate 46d is configured in a manner that one surface faces right and the other surface faces left. One surface of the first side plate 45d is connected to the left ends of the first front plate 45b, the first rear plate 45c, and the first lower plate 45a.

[0090] like Figure 6 As shown, the first side plate 45d of the first bracket 45 is detachably mounted to the left frame 10L of the front axle frame 10 by means of a fastener (bolts and nuts) 52. The second side plate 46d of the second bracket 46 is detachably mounted to the right frame 10R of the front axle frame 10 by means of a fastener (bolts and nuts) 53. However, the first bracket 45 and the second bracket 46 may be mounted to the vehicle body frame 9 (e.g., the side lower portion of the prime mover 5).

[0091] like Figure 6 , Figure 8 , Fig. 9 As shown in FIG. 1 and FIG. 2 , a first lateral portion 40Lb of the first support column 40L is fixed to the first lower plate 45a of the first bracket 45. The first lateral portion 40Lb extends to the right while abutting against the upper surface (one surface of the first horizontal portion 45a1) of the first lower plate 45a of the first bracket 45, and the right end portion abuts against the left surface (one surface) of the first side plate 45d. The first lateral portion 40Lb is fixed to the first bracket 45 by welding or the like. Thus, the lower portion of the first support column 40L is fixed to the first bracket 45.

[0092] The second lateral portion 40Rb of the second support 40R is fixed to the second lower plate 46a of the second bracket 46. The second lateral portion 40Rb extends to the left while abutting against the upper surface (one surface of the second horizontal portion 46a1) of the second lower plate 46a of the second bracket 46, and the left end portion abuts against the right surface (one surface) of the second side plate 46d. The second lateral portion 40Rb is fixed to the second bracket 46 by welding or the like. Thus, the lower portion of the second support 40R is fixed to the second bracket 46.

[0093] like Figure 1 to Figure 4 As shown, the support body 40 has reinforcements 42 and 43 for connecting the pillars (the first pillar 40L and the second pillar 40R) to the vehicle body 2. The reinforcements 42 and 43 include a main reinforcement 42 and a sub-reinforcement 43.

[0094] like Figure 6 , Figure 8 to Figure 10 As shown, the main reinforcement 42 includes a first main reinforcement 42L and a second main reinforcement 42R. The first main reinforcement 42L is a member that reinforces the first pillar 40L, and the second main reinforcement 42R is a member that reinforces the second pillar 40R.

[0095] like Figure 6 to Figure 10 As shown, the sub-reinforcement 43 includes a first sub-reinforcement 43L and a second sub-reinforcement 43R. The first sub-reinforcement 43L is a member that reinforces the first pillar 40L from a different direction from the first main reinforcement 42L. The second sub-reinforcement 43R is a member that reinforces the second pillar 40R from a different direction from the second main reinforcement 42R.

[0096] Hereinafter, the first main reinforcement 42L and the first sub-reinforcement 43L may be collectively referred to as a “first reinforcement”, and the second main reinforcement 42R and the second sub-reinforcement 43R may be collectively referred to as a “second reinforcement”.

[0097] The first reinforcement (the first main reinforcement 42L and the first sub-reinforcement 43L) and the second reinforcement (the second main reinforcement 42R and the second sub-reinforcement 43R) connect the lower portion 401 of the pillar 40 to the vehicle body 2 .

[0098] like Figure 1 , Figure 2 , Figure 4 As shown, the main reinforcement 42 extends from the vertical middle portion of the pillar (the first pillar 40L, the second pillar 40R) (specifically, the vertical middle portion of the lower portion 401) toward the vehicle body 2 in the rear direction (specifically, diagonally downward and rearward). The first main reinforcement 42L connects the vertical middle portion of the first pillar 40L to the vehicle body 2. The second main reinforcement 42R connects the vertical middle portion of the second pillar 40R to the vehicle body 2.

[0099] like Figure 6 , Figure 8 As shown in FIG. 1 and FIG. 2 , one end (upper end) of the first main reinforcement 42L is connected to the first pillar 40L. Specifically, one end of the first main reinforcement 42L is connected to the first longitudinal portion 40La of the first pillar 40L. The first longitudinal portion 40La is provided with a protruding piece 44L protruding toward the rear, and one end of the first main reinforcement 42L is connected to the protruding piece 44L by a fastener (bolt and nut 54).

[0100] like Figure 1 , Fig.12 , Fig.13As shown in the figures, the other end (lower end) of the first main reinforcement 42L is connected to the first step 16L. Specifically, the other end of the first main reinforcement 42L is connected to the first rising portion 17L of the first step 16L. More specifically, the other end of the first main reinforcement 42L is connected to the first rising portion 17L of the first step 16L via the first connecting material 61L.

[0101] like Figure 6 , Fig.13 As shown, the first connecting material 61L includes a front plate 61a, a rear plate 61b, a lower plate 61c, and an upper plate 61d. The front plate 61a and the rear plate 61b are arranged at a distance in the front-to-rear direction and extend in parallel with each other in the vehicle width direction. The lower plate 61c connects the lower end of the front plate 61a with the lower end of the rear plate 61b. The upper plate 61d extends forward from the upper end of the rear plate 61b toward the front plate 61a. Fig.13 As shown, the upper plate 61 d abuts against the lower surface of the upper portion of the first rising portion 17L and is fastened to the lower surface by a fastener (bolt and nut) 55 .

[0102] The other end of the first main reinforcement 42L is connected to the front plate 61a via the first connecting member 62L. Fig.12 , Fig.13 As shown, the first connecting component 62L is composed of a first component 621L and a second component 622L. The first component 621L has a longitudinal plate portion 621La and a transverse plate portion 621Lb. One surface of the longitudinal plate portion 621La faces forward, and the other surface faces backward. The other surface of the longitudinal plate portion 621La abuts against the front plate 61a, and is connected to the front plate 61a of the first connecting material 61L by a fastener (bolts and nuts) 56. The second component 622L is plate-shaped, with one surface facing left and the other surface facing right. The second component 622L abuts against the longitudinal plate portion 621La and the transverse plate portion 621Lb of the first component 621L, and is integrated with the first component 621L by welding or the like.

[0103] like Fig.12 , Fig.13 As shown, a connecting piece 42La is provided at the other end of the first main reinforcement 42L, and the connecting piece 42La is connected to the second part 622L of the first connecting member 62L by a fastener (bolt and nut) 57. Thus, the first main reinforcement 42L is connected to the first connecting material 61L (front plate 61a) via the first connecting member 62L. In addition, the first main reinforcement 42L is connected to the first rising portion 17L of the first step 16 via the first connecting material 61L.

[0104] like Figure 6 , Figure 8As shown in FIG. 1 and FIG. 2 , one end of the second main reinforcement 42R is connected to the second pillar 40R. Specifically, one end of the second main reinforcement 42R is connected to the second longitudinal portion 40Ra of the second pillar 40R. The second longitudinal portion 40Ra is provided with a protruding piece 44R protruding toward the rear, and one end of the second sub-reinforcement 43R is connected to the protruding piece 44R by a fastener (bolt and nut) 58.

[0105] The other end of the second main reinforcement 42R is connected to the second step 16R. The connection structure between the other end of the second main reinforcement 42R and the second step 16R is the same as the connection structure between the other end of the first main reinforcement 42L and the first step 16L, so only the main points are described without detailed illustration and description.

[0106] like Figure 2 As shown, the other end of the second main reinforcement 42R is connected to the second rising portion 17R of the second step 16R. Specifically, the other end of the second main reinforcement 42R is connected to the second rising portion 17R of the second step 16R via the second connecting material 61R (see Figure 6 to Figure 8 ) is connected to the second rising portion 17R of the second pedal 16R. The second connecting member 61R has the same configuration as the first connecting member 61L. Specifically, the second connecting member 61R has a shape symmetrical to the first connecting member 61L across the center of the vehicle body 2 in the vehicle width direction.

[0107] like Figure 6 , Figure 8 , Fig.10 As shown, a connecting piece 42Ra is provided at the other end of the second main reinforcement 42R, and the connecting piece 42Ra is connected to the second connecting component 62R by a fastener (bolt and nut) 59. The structure of the second connecting component 62R is the same as that of the first connecting component 62L. Specifically, the shape of the second connecting component 62R is symmetrical to the first connecting component 62L across the center of the vehicle width direction of the vehicle body 2. The second connecting component 62R is connected to the second connecting material 61R by a fastener (bolt and nut) 60. Thus, the second main reinforcement 42R is connected to the second connecting material 61R via the second connecting component 62R. In addition, the second main reinforcement 42R is connected to the second rising portion 17R of the second pedal 16 via the second connecting material 61R.

[0108] As described above, the first main reinforcement 42L for reinforcing the first support 40L is connected to the first step 16 via the first connecting material 61L. In addition, the second main reinforcement 42R for reinforcing the second support 40R is connected to the second step 16 via the second connecting material 61R. Therefore, the first support 40L and the second support 40R can be reinforced by supporting from the rear (diagonally lower rear) by the first main reinforcement 42L and the second main reinforcement 42R. As a result, the strength (rigidity) of the support body 40 against the force applied from the front can be improved.

[0109] In addition, the first main reinforcement 42L and the second main reinforcement 42R may be configured to extend forward (specifically, diagonally downwardly forward) from the middle portion of the pillars 40L and 40R in the vertical direction toward the vehicle body 2. In this case, since the first main reinforcement 42L and the second main reinforcement 42R are configured to support and reinforce the first pillar 40L and the second pillar 40R from the front (diagonally downwardly forward), the strength (rigidity) of the support body 40 against the force applied from the rear can be increased.

[0110] like Figure 3 , Figure 4 As shown, the sub-reinforcement 43 extends from the vertical middle portion of the pillar (the first pillar 40L, the second pillar 40R) (specifically, the vertical middle portion of the lower portion 401) toward the vehicle body 2 in the vehicle width direction. The first sub-reinforcement 43L connects the vertical middle portion of the first pillar 40L to the vehicle body 2. The second sub-reinforcement 43R connects the vertical middle portion of the second pillar 40R to the vehicle body 2.

[0111] like Figure 8 As shown in FIG. 1 and FIG. 2 , the main reinforcement 42 and the sub-reinforcement 43 are connected to the pillars 40L and 40R at positions offset in the vertical direction. Specifically, the main reinforcement 42 is connected to the pillars 40L and 40R at a position above the sub-reinforcement 43 .

[0112] like Fig. 9 As shown, one end (upper end) of the first auxiliary reinforcement 43L is connected to the first longitudinal portion 40La, and the other end (lower end) is connected to the first transverse portion 40Lb and the first bracket 45 (first side plate 45d). One end (upper end) of the second auxiliary reinforcement 43R is connected to the second longitudinal portion 40Ra, and the other end (lower end) is connected to the second transverse portion 40Rb and the second bracket 46 (second side plate 46d).

[0113] The first sub-reinforcement 43L can reinforce the first pillar 40L from a different direction from the first main reinforcement 42L, that is, the vehicle width direction. In addition, the second sub-reinforcement 43R can reinforce the second pillar 40R from a different direction from the second main reinforcement 42R, that is, the vehicle width direction. Thus, the first pillar 40L and the second pillar 40R are reinforced from both the front-rear direction and the vehicle width direction, and the strength (rigidity) of the support body 40 can be greatly improved.

[0114] In addition, the support body 40 preferably includes both the main reinforcement 42 and the sub-reinforcement 43 as reinforcements, but it is sufficient to include at least one of the reinforcements. In addition, when the main reinforcement 42 is included, it is preferred to include both the first main reinforcement 42L and the second main reinforcement 42R, but it is sufficient to include at least one of the main reinforcements. In the case of the sub-reinforcement 43, it is preferred to include both the first sub-reinforcement 43L and the second sub-reinforcement 43R, but it is sufficient to include at least one of the sub-reinforcements.

[0115] According to the passenger management machine 1 of the above-described embodiment, the following effects are achieved.

[0116] The passenger management machine 1 comprises: a traveling vehicle 1A, which has a vehicle body 2, a driver's seat 4 mounted on the vehicle body 2, and a hood 15 arranged in front of the driver's seat 4; a working machine 1B installed on the traveling vehicle 1A; a position detection device 30 that detects the position of the vehicle body 2 based on a signal from a positioning satellite; and a support body 40 that supports the position detection device 30 above the hood 15, the support body 40 having: a pair of pillars 40L, 40R respectively erected on one side and the other side of the vehicle width direction of the vehicle body 2; a connecting portion 40C connecting the upper ends of the pair of pillars 40L, 40R; and reinforcements 42, 43 that connect the pillars 40L, 40R to the vehicle body 2.

[0117] According to this configuration, since the support body 40 is provided with a structure in which the pillars 40L and 40R are reinforced by the reinforcement members 42 and 43, the position detection device 30 can be reliably supported on the vehicle body 2 by the support body 40. In addition, by supporting the position detection device 30 above the hood 15, it is difficult for the signal from the positioning satellite to be blocked, and the receiving sensitivity can be improved.

[0118] The reinforcement includes a main reinforcement 42 extending forward or rearward from the vertical midpoint of the pillars 40L, 40R toward the vehicle body 2 , and a sub-reinforcement 43 extending in the vehicle width direction from the vertical midpoint of the pillars 40L, 40R toward the vehicle body 2 .

[0119] According to this configuration, the main reinforcement 42 can improve the strength of the support body 40 against the force in the front-rear direction, and the sub-reinforcement 43 can improve the strength of the support body 40 against the force in the vehicle width direction. Therefore, the support body 40 can stably and reliably support the position detection device 30.

[0120] In addition, the main reinforcement 42 and the sub-reinforcement 43 are connected to the pillars 40L and 40R at positions offset in the up-down direction.

[0121] According to this configuration, since the pillars 40L and 40R are supported and reinforced at a plurality of positions in the vertical direction, it is possible to prevent stress concentration from occurring on a portion of the support body 40 , and the support body 40 can be effectively reinforced.

[0122] In addition, the main reinforcement 42 is connected to the pillars 40L and 40R at a position above the sub-reinforcement 43 .

[0123] According to this configuration, the sub-reinforcement 43 can reinforce the support body 40 against the force in the vehicle width direction, and the main reinforcement 42 can effectively reinforce the support body 40 against the force in the front-rear direction, which is a direction in which the support body 40 is more likely to fall than in the vehicle width direction.

[0124] In addition, the pillars 40L and 40R include a first pillar 40L erected on one side of the vehicle body 2 in the vehicle width direction and a second pillar 40R erected on the other side of the vehicle body 2 in the vehicle width direction, and the reinforcement includes a first reinforcement 42L and 43L connecting the middle part of the first pillar 40L in the vertical direction to the vehicle body 2 and a second reinforcement 42R and 43R connecting the middle part of the second pillar 40R in the vertical direction to the vehicle body 2.

[0125] According to this configuration, the pillars 40L and 40R can be reinforced by the reinforcements 42 and 43 on both the one side and the other side in the vehicle width direction of the vehicle body 2 , so that the strength of the support body 40 is improved.

[0126] In addition, the passenger management machine 1 includes: a travel device 3, including front wheels 3F and rear wheels 3R, which support the vehicle body 2 in a travelable manner; a front axle frame 10 that supports the front axle 12 connected to the front wheels 3F; and brackets 45 and 46 that are installed on the front axle frame 10 and fix the lower parts of the pillars 40L and 40R.

[0127] According to this configuration, since the lower portions of the pillars 40L and 40R are attached to the front axle frame 10 via the brackets 45 and 46 , the lower portions of the pillars 40L and 40R can be reliably and stably attached to the vehicle body 2 .

[0128] In addition, the lower end portion of the sub-reinforcement 43 is fixed to the brackets 45 and 46 .

[0129] According to this configuration, since the lower end portion of the sub-reinforcement 43 is attached to the front axle frame 10 via the brackets 45 and 46 , the pillars 40L and 40R can be reliably reinforced by the stable sub-reinforcement 43 .

[0130] Further, at the lower end portions of the pillars 40L and 40R, lateral portions 40Lb and 40Rb extending toward the vehicle width direction inner side and fixed to the brackets 45 and 46 are provided.

[0131] According to this configuration, since the contact portions between the lower ends of the pillars 40L and 40R and the brackets 45 and 46 can be ensured to be long, the lower ends of the pillars 40L and 40R can be fixed to the brackets 45 and 46 with high strength.

[0132] In addition, the lower end portion of the sub-reinforcement 43 is fixed to the lateral portions 40Lb and 40Rb.

[0133] According to this configuration, since the vertical intermediate portions and the lateral portions 40Lb and 40Rb of the pillars 40L and 40R are connected by the sub-reinforcement 43 , the rigidity of the pillars 40L and 40R can be increased.

[0134] The passenger management machine 1 includes a step 16 provided on the side and in front of the driver's seat 4 . One end of the main reinforcement 42 is connected to the pillars 40L and 40R, and the other end is connected to the step 16 .

[0135] According to this configuration, since the pillars 40L and 40R are connected to the pedal 16 via the main reinforcement 42, the force applied from the front of the pillars 40L and 40R can be received by the highly rigid pedal 16. Therefore, the strength (rigidity) of the pillars 40L and 40R against the force from the front can be greatly improved.

[0136] In addition, the support body 40 has a lower portion 401 mounted on the vehicle body 2 and an upper portion 402 detachably mounted on the lower portion 401, the lower portion 401 includes the lower portion of the first pillar 40L and the lower portion of the second pillar 40R, and the upper portion 402 includes the connecting portion 40C, the upper portion of the first pillar 40L, and the upper portion of the second pillar 40R.

[0137] According to this configuration, the support body 40 can be divided into the upper portion 402 and the lower portion 401 , so that the support body 40 can be easily attached to and removed from the vehicle body 2 .

[0138] In addition, the reinforcements 42 and 43 connect the lower portion 402 to the vehicle body 2 .

[0139] According to this configuration, since the lower portions 402 of the pillars 40L and 40R are supported by the reinforcements 42 and 43 , the portions near the bases of the pillars 40L and 40R can be effectively reinforced by the reinforcements 42 and 43 .

[0140] In addition, the first support 40L, the second support 40R, and the connection portion 40C are formed of a circular pipe.

[0141] According to this configuration, the support body 40 can be configured by using a round pipe, which is lightweight and has high strength.

[0142] The above describes one embodiment of the present invention, but it should be considered that the embodiment disclosed this time is illustrative in all aspects and not restrictive. The scope of the present invention is not indicated by the above description, but by the claims, and is intended to include all changes within the meaning and scope equivalent to the claims.
