Description

The present invention relates to a rolling machine, and in particular to a rolling machine equipped with a rolling management device for managing rolling work.

Conventionally, rolling machines equipped with a rolling compaction management device for managing rolling compaction work are known. For example, Patent Document 1 describes a rolling compaction machine equipped with a case that houses a receiver that inputs and processes location information signals received by an antenna and outputs them as location information, a power supply unit that supplies power to the receiver, an arithmetic processing unit that processes the location information output from the receiver, and a display unit that displays the results of the arithmetic processing as rolling compaction management information.

Japanese Patent Application Laid-Open No. 2019-002199

However, in the configuration described in Patent Document 1, the arithmetic processing unit, display unit, and storage case are located on the lifting step, which may hinder the driver's movement when boarding the compaction machine. In other words, to prevent a decrease in work efficiency, it is preferable that the components of the compaction management device be installed in a position that avoids the driver's line of movement as much as possible. In particular, in a compaction machine equipped with a pair of steering wheels, where the driver can operate either steering wheel, installing the components of the compaction management device in the driver's line of movement may contribute to a decrease in work efficiency. On the other hand, if the components of the compaction management device are located too far from the driver's seat to avoid being in the driver's line of movement, the driver will not be able to easily access the compaction management device, which may also result in a decrease in work efficiency.
The present invention has been made in consideration of these problems, and its purpose is to provide a compaction machine that can suppress the decline in the operator's work efficiency caused by the installation of components of a compaction management device.

To achieve the above object, the rolling machine of the present invention comprises a vehicle body, a floor attached to the vehicle body and extending in the vehicle width direction, a first operating device attached to one side of the floor in the vehicle width direction and including a first steering wheel attached to the front of the floor and a first operating seat attached to the rear of the floor corresponding to the first steering wheel, a second operating device attached to the other side of the floor in the vehicle width direction and including a second steering wheel attached to the front of the floor and a second operating seat attached to the rear of the floor corresponding to the second steering wheel, and a rolling management device for managing the rolling work, wherein the rolling management device includes a management terminal that displays rolling management information for the vehicle body, and the management terminal is installed between the first operating device and the second operating device.

This invention makes it possible to prevent a decrease in the operator's work efficiency caused by the installation of components of a rolling compaction management device.

One embodiment of the present invention will be described below with reference to the drawings. In the following description, the front-to-rear and left-to-right directions are expressed relative to the driver seated in the driver's seat of the rolling compaction machine. Note that the left-to-right direction is the same as the vehicle width direction of the rolling compaction machine, and therefore the vehicle width direction will be referred to as the left-to-right direction in the following description.

(First embodiment)
Fig. 1 is a perspective view showing a macadam roller as a rolling machine according to a first embodiment. Fig. 2 is a side view of the macadam roller of Fig. 1, and Fig. 3 is a top view of the macadam roller of Fig. 1. The macadam roller 1A shown in Figs. 1 to 3 is a rolling machine for performing rolling work (compaction work) on a predetermined work area such as a road surface or ground. As shown, the macadam roller 1A includes a vehicle body 10, a rolling roller 11, a lift step 12, a floor plate 13, a driver's seat 14, a seat support base 15, a canopy 16, an operating console 17, a pair of steering wheels 18, and a rolling management device 30 (see Fig. 4).

(Body)
The vehicle body 10 comprises a front vehicle body 10a and a rear vehicle body 10b. The front vehicle body 10a and the rear vehicle body 10b are connected via an articulation mechanism, and by driving a steering cylinder (not shown) provided in the front vehicle body 10a, the front vehicle body 10a and the rear vehicle body 10b bend horizontally around the articulation mechanism, thereby making the vehicle body 10 bendable. An engine room is defined inside the front vehicle body 10a, and equipment related to an engine and an HST (Hydraulic Static Transmission) powered by the engine is installed in the engine room.

(compaction roller)
The compaction rollers 11 are rollers used to compact road surfaces, ground, etc., and include a front compaction roller 11a and a rear compaction roller 11b. The front compaction roller 11a is made up of a pair of metal drums and is rotatably supported on the left and right sides of the front vehicle body 10a. The rear compaction roller 11b is made up of a single metal drum and is rotatably supported by support arms provided on the left and right sides of the rear vehicle body 10b. Each compaction roller 11 is driven by a built-in hydraulic motor for travel, which causes the vehicle body 10 to travel.

(Steps and floor plates)
The steps 12 are provided on the left and right sides of the front body 10a, and are used by the driver of the macadam roller 1A to place his or her feet when boarding. The floor plate 13 is a frame extending horizontally. The floor plate 13 is provided with a floor 13a extending alongside the steps 12 in the left-right direction. The floor 13a is used by the driver seated in the driver's seat 14 to place his or her feet, and also serves as a path for the driver to move left and right.

(Driver's seat)
The driver's seat 14 is provided at the rear of the floor 13a. As shown in FIGS. 1 to 3 , a seat support base 15 that supports the driver's seat 14 is fixed to the floor plate 13, and the upper surface of the seat support base 15 serves as an installation surface 15a for mounting the driver's seat 14. In this embodiment, as shown in the drawings, a pair of driver's seats 14 are fixed to the installation surface 15a of the seat support base 15 at a distance from each other in the left-right direction. That is, the driver's seats 14 include a first driver's seat 141 located on the right side in the left-right direction and a second driver's seat 142 located on the left side in the left-right direction. The first driver's seat 141 is provided corresponding to the first steering wheel 181 of the pair of steering wheels 18. The second driver's seat 142 is provided corresponding to the second steering wheel 182 of the pair of steering wheels 18.

(Canopy)
The canopy 16 is a roof member placed over the driver's seat 14. Note that the canopy 16 is not shown in FIG. 3 . The canopy 16 is supported by legs 162 rotatably connected to a canopy stand 161, which is fixed to the installation surface 15a of the seat support base 15 so as to be positioned between the pair of driver's seats 14. The canopy 16 can be switched between a used state in which it is positioned over the driver's seat 14 and a folded, unused state (see FIGS. 5 and 6 ) by rotating the legs 162 relative to the canopy stand 161. In addition, an antenna 5 of the rolling compaction management device 30, which will be described later, is attached to the canopy 16.

(Operation console)
The operation console 17 is provided at the front of the floor 13a. A pair of steering wheels 18 for operating the travel direction of the macadam roller 1A are mounted on the operation console 17. The operation console 17 is also equipped with a forward/reverse lever 19 (see FIG. 5) for switching between forward and reverse travel of the vehicle body 10, a brake pedal 20 (see FIG. 5) for braking the vehicle body 10, an on-board monitor (not shown) for displaying information about the vehicle body 10 such as the speed and engine RPM of the vehicle body 10, various switches (not shown), and the like. In the example shown in this embodiment, the on-board monitor (not shown) and the various switches are covered by a cover 21 disposed between the pair of steering wheels 18.

(Steering)
The pair of steering wheels 18 are arranged side by side on the operation console 17 with a gap between them in the left-right direction. That is, the pair of steering wheels 18 include a first steering wheel 181 provided on one side of the floor 13a in the left-right direction and in the front of the floor 13a, and a second steering wheel 182 provided on the other side of the floor 13a in the left-right direction (vehicle width direction) and in the front of the floor 13a. The first steering wheel 181 and the first operator's seat 141 are provided in corresponding positions (opposite positions) to each other and constitute a first operating device 25 of the macadam roller 1A. Furthermore, the second steering wheel 182 and the second operator's seat 142 are provided in corresponding positions (opposite positions) to each other and constitute a second operating device 26 of the macadam roller 1A. This allows the driver to perform compaction work using either the first operating device 25 or the second operating device 26, and allows the driver to easily grasp the compaction status of the left and right sides of the macadam roller 1A.

(Rolling compaction management device)
The rolling compaction management device 30 is a device for managing the compaction work performed by the macadam roller 1A. Specifically, the rolling compaction management device 30 is used, for example, to calculate the area compacted by the macadam roller 1A, the number of compactions performed, etc., and display the calculation results to the driver, to allow the driver to input information from form data including various information related to the compaction work, and to issue instructions for starting and ending the compaction work. Figure 4 is a block diagram showing the configuration and electrical connections of the rolling compaction management device 30. As shown in Figure 4, the rolling compaction management device 30 includes an antenna 5, a management unit 40, and a management terminal 50.

Antenna 5 is a GNSS antenna that receives positioning signals (location information signals) from positioning satellites using the GNSS (Global Navigation Satellite System). As described above, antenna 5 is attached to the canopy 16. If the macadam roller 1A does not have a canopy 16, antenna 5 can be attached in a position where there are no obstacles around, and especially no obstacles above, that could obstruct reception of the positioning signal. Antenna 5 outputs the positioning signal to the receiver 41 of the management unit 40, which will be described later.

The management unit 40 includes a receiver 41 and a power supply 42. The receiver 41 receives the positioning signal received by the antenna 5, calculates the position of the macadam roller 1A's body 10, and outputs the calculated position to the management terminal 50. The power supply 42 is a stabilized power supply that supplies power to the receiver 41. Power is supplied to the power supply 42 from an onboard power supply 66 (see Figure 4), which will be described later. The rolling compaction management device 30 also includes a storage case 43 (see Figures 1 to 3) as a housing, and the management unit 40 is removably stored in the storage case 43.

The management terminal 50 is a computer having an arithmetic processing unit 51 and a display unit 52, and displays compaction management information for the vehicle body 10. The management terminal 50 may be, for example, a notebook computer or a tablet computer. The arithmetic processing unit 51 processes the current position information of the macadam roller 1A obtained from the management unit 40 (described below) to calculate the area compacted by the macadam roller 1A and the number of times that area has been compacted. The arithmetic processing unit 51 also generates report data containing various information related to the compaction work, linking it to the results of the arithmetic processing. The display unit 52 is a touch-panel monitor attached to the arithmetic processing unit 51. The display unit 52 is electrically connected to the arithmetic processing unit 51 and displays the results of the arithmetic processing unit 51, i.e., compaction management information such as the area compacted by the macadam roller 1A and the number of times that area has been compacted, to the driver. The display unit 52 also accepts input from the driver, such as information required to generate the above-mentioned report data and instructions to start and end compaction work, and outputs this to the arithmetic processing unit 51.

As shown in FIG. 4, the antenna 5, management terminal 50, and management unit 40 are electrically connected via connectors 61 and 62. Although not shown, in this embodiment, connectors 61 and 62 are connected by storing the management unit 40 in a storage case 43. The antenna 5 and management terminal 50 are also electrically connected to an onboard control device 65, which performs overall control and is mounted on the vehicle body 10, and an onboard power supply unit 66. By connecting connectors 61 and 62, positioning signals from the antenna 5 and information such as the operating status of the macadam roller 1A are input to the receiver 41, and the receiver 41 outputs position information obtained by processing the positioning signals to the management terminal 50. Furthermore, the power supply unit 42 and the onboard power supply unit 66 can exchange power with each other via connectors 61 and 62.

(Installation configuration of rolling compaction management device)
Next, the installation configuration of the rolling compaction management device 30 on the macadam roller 1A will be described. First, as shown in Figures 1 and 3, the management terminal 50 is installed between the first operating device 25 and the second operating device 26. More specifically, the management terminal 50 is placed in the center in the left-right direction of the sheet support base 15, i.e., between the first operating seat 141 and the second operating seat 142, and is installed on the installation surface 15a, with the display unit 52 facing upward.

The management terminal 50 is installed on the installation surface 15a so that it can rotate and adjust its angle. Figure 5 is an explanatory diagram showing the initial state of the management terminal 50, and Figure 6 is an explanatory diagram showing the management terminal 50 rotated from the initial state to a usage state. Note that for the sake of explanation, Figures 5 and 6 omit the illustration of the first operator's seat 141 located on the right side. As shown in Figure 5, the management terminal 50 is provided with a pair of left and right connecting portions 55 on the back surface 50a opposite the display unit 52, and a pair of left and right support portions 151 are provided on the installation surface 15a of the seat support base 15 at positions corresponding to the connecting portions 55. The connecting portions 55 are provided near the end of the management terminal 50 on the side opposite the floor 13a. The management terminal 50 is connected to the support portions 151 by the connecting portions 55 so that it can rotate around a horizontal axis. As shown in Figure 5, in the initial state, the management terminal 50 maintains its orientation so that the screen of the display unit 52 faces vertically upward.

As shown in FIG. 6 , the management terminal 50 can be rotated around the connecting portion 55 and the support portion 151 as a pivot point, so that the floor 13a-side end of the management terminal 50 moves upward, thereby adjusting the angle of the display unit 52 screen to be closer to the driver seated in the driver's seat 14. In this case, the canopy stand 161 is used as a stopper, making it easy to adjust the management terminal 50 to the desired angle without the need for a dedicated stopper. If the macadam roller 1A does not have a canopy 16, a dedicated stopper can be provided separately on the installation surface 15a. In this embodiment, since the macadam roller 1A has a canopy 16, when the canopy 16 is folded and not in use, the legs 162 are positioned above the management terminal 50, as shown in FIGS. 5 and 6 . Therefore, the management terminal 50 is installed at a height that does not interfere with the legs 162 of the canopy 16 when not in use.

Next, the installation configuration of the management unit 40, i.e., the installation configuration of the storage case 43, will be described. The storage case 43 that stores the management unit 40 is installed behind the driver's seat 14, as shown in Figures 1 to 3. More specifically, the storage case 43 is installed behind the first driver's seat 141, which is located on the right side in the left-right direction. The storage case 43 may also be installed behind the second driver's seat 142, which is located on the left side in the left-right direction.

Figure 7 is an explanatory diagram showing a storage case 43 installed on the back of the first operator's seat 141. As shown in the figure, a case support member 70 that supports the storage case 43 is provided on the back of the first operator's seat 141. The case support member 70 has a bottom plate portion 71 that supports the storage case 43 and an attachment portion 72 that rises upward from the bottom plate portion 71. One attachment portion 72 rises from each of the left and right ends of the bottom plate portion 71. At the upper end of the case support member 70, the attachment portion 72 is connected to a handrail pipe 81 that extends around the operator's seat 14 via a clamp 73 and a bolt and nut. Furthermore, the case support member 70 is connected to a handrail pipe 82 that extends around the first operator's seat 141 via a clamp 74 and a bolt and nut on the underside of the bottom plate portion 71. Note that if the pipe 82 is located further forward, a clamp 74 may be attached near the lower end of the attachment portion 72 in the same orientation as the clamp 73 and connected to the pipe 82. This eliminates the need to position the bottom plate 71 above the pipe 82, and depending on the routing position of the pipe 82, the case support member 70 and therefore the storage case 43 can be positioned further downward.

The storage case 43 is placed via two spacers 45 on the bottom plate portion 71 of the case support member 70, which is attached to the back of the first operator's seat 141 as described above. The storage case 43 is then connected to the case support member 70 by a number of bolts 83 that penetrate the bottom portion 43a, spacers 45, and bottom plate portion 71, and a number of nuts 84 that are positioned on the underside of the bottom plate portion 71 and into which each bolt 83 is screwed.

As shown in FIG. 7 , the storage case 43 has an access opening 431 formed on the outward-facing side in the left-right direction for removing the management unit 40. The management unit 40 is housed within the storage case 43 so that it can slide freely relative to the bottom 43a, and the management unit 40 can be easily removed from the storage case 43 via the access opening 431. Although not shown in FIG. 7 , a door 432 that can be opened and closed is attached to the access opening 431, as shown in FIGS. 1 and 2 . When the management unit 40 does not need to be removed, the access opening 431 is closed by the door 432. In the configuration shown in FIG. 7 , the height from the ground to the storage case 43 is approximately 1.9 meters. Therefore, when removing the management unit 40 from the storage case 43 for maintenance or other purposes, personnel can access the storage case 43 from the ground using a tool such as a stepladder and open and close the door 432.

As shown in FIG. 7 , the storage case 43 has an opening 433 formed on its top surface. The opening 433 allows the driver to access the receiver 41 inside the storage case 43. Although not shown, the receiver 41 is equipped with buttons that the driver uses to operate the receiver 41, lamps that indicate the operating status of the receiver 41, a monitor, and the like. Through the opening 433, the driver can, for example, turn the receiver 41 on and off, perform various settings, and check when an error occurs, and can also check the settings of the receiver 41 or the details of any errors that have occurred by checking the lamps and monitor. Although not shown in FIG. 7 , the opening 433 is equipped with a door 434 that can be opened and closed, as shown in FIG. 1 . When the driver does not need to access the management unit 40, the door 434 closes the opening 433.

(Effects of the first embodiment)
As described above, the macadam roller 1A of the first embodiment includes the vehicle body 10, the floor 13a provided on the vehicle body 10 and extending in the left-right direction (vehicle width direction), the first operating device 25 provided on one side of the floor 13a in the left-right direction and including a first steering wheel 181 provided in the front of the floor 13a and a first operating seat 141 provided in the rear of the floor 13a corresponding to the first steering wheel 181, the second operating device 26 provided on the other side of the floor 13a in the left-right direction and including a second steering wheel 182 provided in the front of the floor 13a and a second operating seat 142 provided in the rear of the floor 13a corresponding to the second steering wheel 182, and a rolling compaction management device 30 for managing the rolling work. The rolling compaction management device 30 includes a management terminal 50 that displays rolling management information for the vehicle body 10, and the management terminal 50 is installed between the first operating device 25 and the second operating device 26.

With this configuration, the management terminal 50 of the rolling compaction management device 30 is installed between the first operating device 25 and the second operating device 26, allowing the driver to board the floor 13a from either the left or right step 12. In other words, the management terminal 50 can be positioned to avoid the driver's line of movement as much as possible. Furthermore, whether the driver is seated in the first operating seat 141 or the second operating seat 142, the driver can easily access the management terminal 50 and operate it via the display unit 52. Therefore, with the macadam roller 1A of the first embodiment, it is possible to prevent a decrease in the driver's work efficiency caused by the installation of components of the rolling compaction management device 30.

The management terminal 50 is installed between the first operator's seat 141 and the second operator's seat 142, on the installation surface 15a of the first operator's seat 141 and the second operator's seat 142.

With this configuration, the management terminal 50 is installed on the installation surface 15a of the driver's seat 14, eliminating the need to mount the management terminal 50 on the floor 13a. As a result, the management terminal 50 is prevented from interfering with the driver's movement on the floor 13a, particularly between the first driver's device 25 and the second driver's device 26. Furthermore, the driver can easily access the management terminal 50 whether he or she is seated in the first driver's seat 141 or the second driver's seat 142.

Furthermore, as described above, the management terminal 50 is positioned at a height that does not interfere with the legs 162, i.e., near the installation surface 15a. By positioning the management terminal 50 between the pair of driver's seats 14 and near the installation surface 15a in this way, the field of vision of the driver performing compaction work using the management terminal 50 is not obstructed, ensuring good visibility for the driver.

However, if the macadam roller 1A does not have a canopy 16, or if there is no interference between the legs 162 and the management terminal 50, the height position of the management terminal 50 is not limited to that exemplified in this embodiment. For example, legs may be provided between the rear surface 50a of the management terminal 50 and the installation surface 15a, and the length of the legs may be adjusted to install the management terminal 50 at a desired height. The management terminal 50 may also be installed at a desired height by attaching it to the legs 162 of the canopy 16 via an attachment member (not shown). However, it is preferable that the attachment member does not obstruct the driver's view. When installing the management terminal 50 away from the installation surface 15a, it is preferable that the management terminal 50 be positioned at least below the upper ends 14a of the backrests of the first and second driver's seats 141 and 142 (see Figures 5 and 6). This ensures good driver visibility.

In addition, in the first embodiment, the management terminal 50 can be rotated to adjust its angle. This configuration allows the driver to rotate the management terminal 50 and easily adjust the angle to make the screen easier to view. As mentioned above, even when the management terminal 50 is installed away from the installation surface 15a, it is preferable that the management terminal 50 be configured to be able to rotate and adjust its angle.

In addition, in the first embodiment, the rolling compaction management device 30 includes a receiver 41 that calculates the position information of the vehicle body 10 based on the positioning signal (position information signal) received by the antenna 5, a management unit 40 having a power supply device 42 that supplies power to the receiver 41, and a storage case 43 that stores the management unit 40, and the storage case 43 is installed behind either the first driver's seat 141 or the second driver's seat 142.

With this configuration, the management unit 40 is not mounted on the step 12 or floor 13a, which prevents the storage case 43 from interfering with the movement of the driver, particularly when moving across the floor between the first operating device 25 and the second operating device 26. Furthermore, by installing the storage case 43 behind the driver's seat 14, the driver seated in the driver's seat 14 can easily access the management unit 40 inside the storage case 43.

In addition, in the first embodiment, the storage case 43 has an outlet 431 formed on the side facing outward in the left-right direction for removing the management unit 40.

With this configuration, as described above, personnel can access the storage case 43 from the ground using a tool such as a stepladder, and easily remove the receiver 41 and power supply unit 42 from the storage case 43 through the access port 431.

Second Embodiment
Next, a second embodiment will be described with reference to Figure 8. Figure 8 is a perspective view showing a macadam roller as a rolling machine according to the second embodiment. The macadam roller 1B shown in Figure 8 differs from the macadam roller 1A according to the first embodiment in the installation configuration of the storage case 43 and the management terminal 50. The other configuration of the macadam roller 1B is the same as that of the macadam roller 1A, so the same components are denoted by the same reference numerals and detailed description will be omitted.

As shown in Figure 8, in the macadam roller 1B, the storage case 43 that stores the management unit 40 is installed on the installation surface 15a of the seat support base 15 between the first operator's seat 141 and the second operator's seat 142. At this time, as shown in the figure, the storage case 43 is installed horizontally with the access opening 431 (see Figure 7) and door 432 facing forward. This allows the management unit 40 to be easily removed from the storage case 43 through the access opening 431. Also, in the macadam roller 1B, the management terminal 50 is installed on top of the storage case 43 with the screen of the display unit 52 facing upward. Note that, in the second embodiment as well, it is preferable that the management terminal 50 be rotatable to adjust the angle.

(Effects of the second embodiment)
With this configuration, the storage case 43 and the management terminal 50 are not mounted on the driver's path of movement, i.e., on the step 12 or the floor 13a. As a result, the movement of the driver, particularly when moving on the floor between the first operating device 25 and the second operating device 26, is prevented from being hindered by the storage case 43 and the management terminal 50. Furthermore, because the storage case 43 and the management terminal 50 are installed between the first operating seat 141 and the second operating seat 142, the driver seated in the operating seat 14 can easily access the management unit 40 and the management terminal 50. Therefore, the macadam roller 1B of the third embodiment can prevent a decrease in the driver's work efficiency caused by the installation of components of the rolling compaction management device 30.

In addition, because the storage case 43 and management terminal 50 are installed on the installation surface 15a in a stacked position, the driver's field of vision is not obstructed by the storage case 43 and management terminal 50, ensuring the driver's visibility.

Furthermore, when the storage case 43 and management terminal 50 are installed on the installation surface 15a in a stacked manner, the legs 162 are likely to interfere with the management unit 40 and management terminal 50 when the canopy 16 is not in use. Therefore, although not shown in Figure 8, it is preferable that the legs 162 be bent so as to avoid the management unit 40 and management terminal 50.

(Third embodiment)
Next, a third embodiment will be described with reference to Figure 9. Figure 9 is a perspective view showing a macadam roller as a rolling machine according to the third embodiment. The macadam roller 1C shown in Figure 9 differs from the macadam roller 1A in the installation position of the management terminal 50. Since the other configuration of the macadam roller 1C is the same as that of the macadam roller 1A, the same components are assigned the same reference numerals and detailed description will be omitted.

As shown in Figure 9, in the macadam roller 1C, the management terminal 50 is installed on the operation console 17. The operation console 17 has a mounting panel (mounting surface) 171 to which a cover 21 is attached, which covers the first steering wheel 181, the second steering wheel 182, the on-board monitor (not shown), and various switches, and a front panel 172 extending downward from the mounting panel 171. As illustrated in Figures 5 and 6, the cover 21 is configured to protrude slightly toward the floor 13a beyond the front panel 172.

The management terminal 50 is installed in the horizontal center of the front panel 172 so that the screen of the display unit 52 faces the driver's seat 14. Therefore, in the third embodiment, the management terminal 50 is also located between the first operating device 25 and the second operating device 26. More specifically, the management terminal 50 is installed on the operation console 17 below the mounting panel 171 to which the first steering wheel 181, the second steering wheel 182, and the cover 21 are attached. In the example shown in FIG. 9, the cover 21 extends to the horizontal center of the operation console 17 (see FIG. 3), so the management terminal 50 is located below the cover 21. As described above, the cover 21 protrudes slightly toward the floor 13a beyond the front panel 172. In the mounted state shown in FIG. 9, the management terminal 50 is preferably installed on the front panel 172 so that it does not protrude toward the floor 13a beyond the cover 21.

The management terminal 50 is mounted on the operation console 17 so that it can be rotated relative to the front panel 172 and pulled out above the floor 13a. Figure 10 is a perspective view showing the management terminal 50 of the third embodiment in a rotated state. For example, the upper end of the back surface 50a of the management terminal 50 may be provided with the connecting portion 55 illustrated in Figures 5 and 6, and the front panel 172 may be provided with the support portion 151 illustrated in Figures 5 and 6, and the management terminal 50 may be connected so that it can rotate around a horizontal axis. As a result, as shown in Figure 10, the upper end of the management terminal 50 can be used as a pivot point to rotate the lower end of the management terminal 50 in a lifting direction, adjusting the angle so that it is closer to the driver. Furthermore, as shown in Figure 10, a retractable support member 90 may be provided on the floor plate 13 to support the back surface 50a of the management terminal 50 when it is rotated.

(Effects of the third embodiment)
With this configuration, the management terminal 50 is not mounted on the driver's path of movement, i.e., on the step 12 or the floor 13a, and therefore the movement of the driver, particularly when moving on the floor between the first operating device 25 and the second operating device 26, is prevented from being hindered by the management terminal 50. Furthermore, since the management terminal 50 is installed in the center of the operation console 17 in the left-right direction, the driver seated in the driver's seat 14 can easily access the management terminal 50. Therefore, with the macadam roller 1C of the third embodiment, it is possible to prevent a decrease in the driver's work efficiency caused by the installation of the components of the compaction management device 30.

The management terminal 50 is also installed on the operation console 17 below the mounting panels 171 of the first steering wheel 181 and the second steering wheel 182. This configuration ensures that the driver's field of vision is not obstructed and ensures good visibility for the driver.

The management terminal 50 can also be rotated and pulled out from the operation console 17 above the floor. This configuration allows the driver to rotate the management terminal 50 and pull it out to a position closer to the driver's seat 14 at their own discretion when entering information via the management terminal 50 or when they want to view the screen closer.

This concludes the description of the embodiments, but the aspects of the present invention are not limited to the first to third embodiments. The configurations of the first to third embodiments may be combined as appropriate. For example, in the macadam roller 1C of the third embodiment, the storage case 43 may be installed on the installation surface 15a of the seat support base 15 between a pair of operator seats 14, as in the macadam roller 1B of the second embodiment.

In addition, in the first to third embodiments, a pair of operator seats 14 are installed on the seat support base 15. However, if the canopy stand 161 is not installed and both the storage case 43 and the management terminal 50 are not installed on the seat support base 15 as in the macadam roller 1C of the third embodiment, a bench seat extending in the left-right direction may be installed on the installation surface 15a of the seat support base 15.
