In the tire roller disclosed in Patent Document 1, dirt, dust, etc. inside the water tank or the like may enter the spray nozzle or the water nozzle and cause clogging.

When the spray nozzle or water nozzle becomes clogged in this way, the operator needs to temporarily interrupt the compaction operation and replace the spray nozzle or water nozzle. Therefore, the operator needs to have spare spray nozzles and water nozzles (spare parts) in advance for replacing the spray nozzles and water nozzles. However, when preparing spare parts, if you do not store them properly, you will not be able to replace them immediately when necessary, and even if you replace them, the nozzle will already be clogged with dust and the replaced spare parts will not be used. There may be a situation where this is not possible. If this happens, there is a risk that the compaction work will have to be interrupted.

The present invention has been made in view of these problems, and its purpose is to provide spare parts for rolling work-related parts used in a rolling machine during rolling work in an appropriate state. Our goal is to provide compaction machines.

In order to achieve the above object, the rolling machine of the present invention is formed surrounded by a frame that constitutes the frame of the machine body, an engine that drives the rolling compaction roller is supported and housed in the frame, and a cover is provided.

As a result, the mounting member to which the spare parts are attached is placed in the engine room of the aircraft so that at least the upper side can be opened and closed by the cover, so the operator can easily carry out rolling pressure without having to carry spare parts on hand. It is now possible to prepare for the failure of work-related parts, and for example, even when the aircraft is parked outdoors for a long period of time, it is possible to prevent water, dust, etc. from adhering to spare parts. .

In another aspect, the air blower is disposed in the engine room and generates cooling air that flows in the longitudinal direction of the aircraft body in the engine room, and the mounting member is installed in the engine room in the longitudinal direction of the aircraft body. It is preferable that it be extended to.

As a result, the blower generates cooling air that flows in the longitudinal direction of the aircraft in the engine room, and the mounting member to which the spare parts are attached is installed in the engine room so as to extend in the longitudinal direction of the aircraft. The mounting member to which the spare parts are attached can be placed in the engine room without interfering with the cooling air flowing in the longitudinal direction of the aircraft body.

In another aspect, the mounting member is a flat plate member that is erected on the frame at a position facing a side wall of the cover on either side in the left-right direction in the engine room, and the spare part is: It is preferable that the flat plate member be disposed on a surface facing outside of the fuselage.

As a result, by arranging the spare parts in a position on the mounting member where the flow of cooling air from the blower is relatively small, dust contained in the cooling air flowing in the engine compartment by the blower does not hit the spare parts. This makes it possible to effectively suppress clogging of spare parts due to dust, etc. Further, when the engine cover is opened, the operator can easily attach and detach the spare parts attached to the attachment member from outside the aircraft body.

In another aspect, the attachment member is a flat plate member that is erected on the frame and extends in the front-rear direction of the aircraft body, and the flat plate member has at least two upper and lower attachment parts to which the spare parts are attached.

<First embodiment>
Hereinafter, a first embodiment of the present invention will be described based on the drawings.

Referring to FIG. 1, a top view of a fuselage 1 is shown. The body 1 is a tire roller including a front wheel (compaction roller) 3 and a rear wheel 5. The front wheels 3 and the rear wheels 5 are rubber rolling rollers that can compact the ground with optimal surface pressure. Here, for example, three front wheels 3 are arranged side by side in the left-right direction of the aircraft body 1.

The fuselage 1 is equipped with a spray device 11 and a drive device 13. The spraying device 11 sprays water and a liquid agent stored in a water tank and a liquid agent tank (not shown) onto the front wheels 3 and rear wheels 5 to suppress adhesion of paving material to the front wheels 3 and rear wheels 5. It is a device. This spray device 11 has a supply pipe 21, a water spray nozzle (component related to compaction work) 23, and a spray nozzle (component related to compaction work) 25.

The supply piping 21 is configured to supply water and liquid agent sucked up from a water tank and a liquid agent tank by a pump (not shown) to the water spray nozzle 23 and the spray nozzle 25, respectively. The water nozzle 23 is a nozzle that atomizes and sprays water supplied to the front wheels 3 via the supply pipe 21. The spray nozzle 25, like the water spray nozzle 23, is a nozzle that atomizes and sprays the liquid agent supplied to the front wheels 3 via the supply pipe 21. These water nozzles 23 and spray nozzles 25 are arranged near each front wheel 3. Further, the water spray nozzle 23 and the spray nozzle 25 are configured to be detachable from the supply piping 21 by an operator without using tools or the like.

The drive device 13 is a device that generates driving force for at least one of the front wheels 3 and the rear wheels 5, and is disposed in the engine room 7. This drive device 13 has an engine 31, a radiator 33, and a cooling fan (air blower) 35. The engine 31 is an internal combustion engine that operates by burning fuel stored in a fuel tank (not shown). The radiator 33 is a cooling device that cools the engine 31 by circulating cooling water flowing through a water jacket (not shown) formed inside the engine 31 and exchanging heat with the atmosphere.

The cooling fan 35 is a fan that rotates using the driving force generated when the engine 31 operates, and circulates air from the front to the rear of the aircraft. As a result, the drive device 13 generates driving force by operating the engine 31, and also drives the cooling fan 35 to pass air from the front of the aircraft through the radiator 33, thereby reducing the heat generated when the engine 31 is operating. It is possible to cool with a radiator 33.

Here, the engine room 7 is formed by surrounding the frame 2 on the side and lower surfaces of the body 1 in the longitudinal and lateral directions. Further, the engine room 7 is covered with an engine cover 9 that can be opened and closed on the upper side. The engine cover 9 has a side wall 9a and is connected to the frame 2 via, for example, a hinge (not shown) provided at the front end, and can be opened and closed by rotating around the front end. Therefore, the engine room 7 is closed by closing the engine cover 9, and opened by opening the engine cover 9. By opening the engine room 7 in this way, the operator can perform maintenance on the drive device 13 and the like.

As the cooling fan 35 is driven as described above, a wind (cooling wind) W flowing from the front of the aircraft toward the rear is generated in the engine room 7 . The wind W forms a mainstream in the center of the aircraft body 1 in the left-right direction, and the flow velocity is high. The air flowing by this wind W not only cools the cooling water circulating through the engine 31 in the radiator 33 but also lowers the atmospheric temperature in the engine room 7. Therefore, in the engine room 7, even when the engine cover 9 is closed, the atmospheric temperature can be lowered by the wind W generated by the cooling fan 35.

Referring to FIG. 2, a view of the spare parts unit 40 and its surroundings is shown from the front of the aircraft. Further, referring to FIG. 3, there is shown an exploded perspective view of the spare parts unit 40 viewed from the front upper left. As shown in FIGS. 2 and 3, a spare parts unit 40 is disposed in the engine room 7 on the left side in the left-right direction of the aircraft body 1, in other words, at a position away from the mainstream of the wind W. Specifically, the spare parts unit 40 is attached to the frame 2 so as to be located on the outer side of the fuselage than the drive device 13, and is covered by the engine cover 9 when the engine cover 9 is closed.

This spare parts unit 40 includes a base 41, a preliminary watering nozzle (spare part) 43, and a preliminary spray nozzle (spare part) 45. Hereinafter, for convenience of explanation, the water sprinkling nozzle 23 and the spray nozzle 25 that are attached to the spray device 11 and used are also referred to as the used water spray nozzle 23 and the used spray nozzle 25 in order to distinguish them from the preliminary water spray nozzle 43 and the preliminary spray nozzle 45. say.

The base 41 includes a mounting member 51, a locking member (attached portion) 53, and a label 54. The mounting member 51 is made of a flat plate member, and has a mounting portion 60 and a fixing portion 61 formed by cutting and bending a steel plate, for example, and a screw hole 63 and an inclined portion 65 are formed in the mounting portion 60.

The mounting member 51 is configured to extend in the same direction as the flow of wind W from the front to the rear of the fuselage generated by the cooling fan 35, that is, in the front-rear direction of the fuselage 1, and is located inside the engine room 7 and located near the engine cover 9. It is arranged near the side wall 9a. As a result, the mounting member 51 is located at a position that is deviated from the center of the engine room 7 in the left-right direction and is deviated from the mainstream of the wind W, and the mounting portion 60 is located along the flow of the wind W. be arranged so as not to interfere with

The fixing part 61 is a flat plate part extending from the lower end of the mounting part 60 at right angles to the left side of the body. This fixing portion 61 is fixed to a pedestal 2a attached to the frame 2 with bolts 55. Therefore, the mounting member 51 is erected on the frame 2 via the pedestal 2a, and the fixing part 61 is fixed to the pedestal 2a, so that the mounting part 60 is perpendicular to the pedestal 2a and thus to the frame 2. It is configured. The attachment member 51 can be easily attached to and detached from the body 1 by attaching and detaching the bolts 55. For example, seven screw holes 63 are formed, each forming a female screw portion.

Referring to FIG. 4, a front view of spare parts unit 40 is shown. The screw holes 63 are configured in two rows: an upper row L1, which is an upper row, and a lower row L2, which is a lower row. Three screw holes 63 are formed in the upper row L1, and four screw holes 63 are formed in the lower row L2. That is, a smaller number of screw holes 63 are provided in the upper row L1 than in the lower row L2, and the screw holes 63 in the upper row L1 are arranged in a so-called zigzag pattern above between the adjacent screw holes 63 in the lower row L2. It will be located. Note that the screw hole 63 in the center of the screw holes 63 in the upper row L1 when viewed in the front-rear direction of the fuselage 1 is not used in this example, so it is covered with a blind cover 63a.

The inclined portions 65 are formed on both the front and rear sides of the attachment portion 60 when viewed in the longitudinal direction of the body 1. The inclined portions 65 are inclined at, for example, 45 degrees with respect to the upper side of the mounting portion 60. Thereby, the mounting member 51 can improve the visibility and maintainability of the drive device 13 for the operator when the operator performs maintenance of the drive device 13 or the like.

The locking member 53 is a member that locks the pre-watering nozzle 43 and the pre-spray nozzle 45 on the left side in the left-right direction of the machine body 1. The screw hole 63 is located on a surface facing outward (a surface facing the inner surface of the side wall 9a of the engine cover 9) and is fixed in a screw hole 63. Here, the left surface of the mounting portion 60 in the left-right direction of the fuselage 1 is further away from the mainstream of the wind W compared to the right-hand surface of the fuselage 1 in the left-right direction, and is further separated from the mainstream of the wind W by the mounting portion 60. , it is a surface where there is little flow of wind W. This locking member 53 includes a hexagonal portion 71, a male screw portion 73, and a locking portion 75.

The hexagonal portion 71 is formed in a shape corresponding to the head of a hexagonal bolt. The male threaded portion 73 is a threaded portion having a shape corresponding to the lower neck of a hexagonal bolt, and the pitch etc. correspond to the threaded hole 63. As a result, the locking member 53 can be firmly fixed to the mounting member 51 by screwing the male threaded portion 73 into the screw hole 63 from the left side in the left-right direction of the fuselage 1 and tightening the hexagonal portion 71 with a hex wrench or the like. be.

The locking portion 75 includes a cylindrical portion extending from the hexagonal portion 71 to the side opposite to the male threaded portion 73, and a cylindrical portion extending radially outward from the tip of the cylindrical portion at a constant angle with respect to the axial center of the cylindrical portion. and arc-shaped claws that protrude and extend point-symmetrically within the range. The preliminary watering nozzle 43 and the preliminary spray nozzle 45 are locked and unlatched to this locking portion 75 . Specifically, according to FIG. 4, the locking part 75 is rotated clockwise around the central axis of the cylindrical part so that the locking part 75 and the preliminary spray nozzle 43 are rotated clockwise around the central axis of the columnar part. The preliminary watering nozzle 43 and the preliminary spray nozzle 45 can be locked to the locking portion 75 by releasing the locking state with the preliminary water spray nozzle 43 and the preliminary spray nozzle 45 and rotating it counterclockwise.

The preliminary watering nozzle 43 and the preliminary spraying nozzle 45 have the same structure as the used watering nozzle 23 and the used spraying nozzle 25, respectively. Specifically, according to FIG. 3, the pre-watering nozzle 43 includes a nozzle support 81, a nozzle portion 83, and a knob 85. The nozzle support body 81 is a tapered hollow member whose one end is locked to the locking part 75 and whose other end can support the nozzle part 83 and supply water to the nozzle part 83. From this, when the preliminary watering nozzle 43 is locked to the not-shown locking part of the supply pipe 21 instead of the used watering nozzle 23, the nozzle support 81 directs water from the supply pipe 21 toward the nozzle part 83. Distribution is possible (see Figure 1). The nozzle portion 83 is a nozzle that can discharge water in the form of mist when water is supplied from the supply pipe 21 via the nozzle support 81 . The knob 85 is a flat plate-shaped portion extending radially outward from the nozzle support 81 .

Therefore, by replacing the used watering nozzle 23, the preliminary watering nozzle 43 locks one end of the nozzle support 81 with the supply pipe 21, so that the water supplied from the supply pipe 21 is atomized by the nozzle part 83. can be sprayed onto the front wheels 3. Further, since the knob 85 is formed on the preliminary watering nozzle 43, the operator can easily rotate the preliminary watering nozzle 43 using the knob 85. Thereby, the operator can lock and unlatching the preliminary watering nozzle 43 to and from the locking portion (not shown) of the supply pipe 21 and the locking portion 75 of the locking member 53 without using any tools.

The preliminary spray nozzle 45 has the same structure as the preliminary water spray nozzle 43, except that the nozzle portion 83 of the preliminary water spray nozzle 43 has a shape optimized for spraying a liquid agent, so a description thereof will be omitted here.

Here, according to FIG. 4, as described above, the screw holes 63 in the upper row L1 are located above between the adjacent screw holes 63 in the lower row L2. Therefore, the locking members 53 (upper attached portions) in the upper row L1 are located above between the adjacent locking members 53 (lower attached portions) in the lower row L2.

The label 54 is a seal member that is located near each of the locking members 53 to which the preliminary watering nozzle 43 and the preliminary spray nozzle 45 are attached, and is attached to the attachment portion 60. This label 54 includes, for example, descriptions such as "water spray nozzle" and "spray nozzle" so that the operator can distinguish between the preliminary water spray nozzle 43 and the preliminary spray nozzle 45.

Next, the effects of the spare parts unit 40 according to the first embodiment will be explained.
When clogging occurs in the used water sprinkler nozzle 23 and the used spray nozzle 25, the operator replaces the used water sprinkler nozzle 23 and the used spray nozzle 25 with the preliminary watering nozzle 43 and the preliminary spray nozzle 45. Therefore, by disposing the spare parts unit 40 in the machine body 1, the operator can avoid clogging of the used water sprinkler nozzle 23 and the used spray nozzle 25 without having to carry the preliminary watering nozzle 43 and the preliminary spraying nozzle 45 at hand. You can prepare.

In particular, compaction machines such as the machine body 1 are more often rented to operators from rental companies and used than other construction machines. Therefore, for the rental business, by installing the spare parts unit 40 in the aircraft 1, when renting the aircraft 1 to an operator, the preliminary water nozzle 43 and the preliminary spray nozzle 45 can be rented separately from the aircraft 1. This trouble can be eliminated. On the other hand, the operator can prepare for clogging of the used water sprinkler nozzle 23 and the used spray nozzle 25 without losing the preliminary water spray nozzle 43 and the preliminary spray nozzle 45 lent to the rental company.

In the compaction machine according to the present invention, the engine 31 is formed surrounded by the frame 2 that constitutes the frame of the machine body 1, and is supported by and housed in the frame 2, and the engine 31 that drives the front wheels 3 and the rear wheels 5. In a rolling compaction machine comprising an engine room 7 whose upper side is covered at least by an engine cover 9 so as to be openable and closable, and a water spray nozzle 23 and a spray nozzle 25 used during compaction work in the machine body 1, the water spray nozzle 23 and the spray nozzle 25 are used. It has a preliminary watering nozzle 43 and a preliminary spraying nozzle 45 that are used as backups for the spraying nozzle 25, and a mounting member 51 to which these preliminary watering nozzle 43 and preliminary spraying nozzle 45 are attached, and the mounting member 51 is installed in the engine room 7. It is arranged so as to be covered by an engine cover 9.

Therefore, by disposing the mounting member 51 to which the preliminary water spray nozzle 43 and the preliminary spray nozzle 45 are attached in the engine room 7 of the aircraft body 1 so that at least the upper side is covered by the engine cover 9 so as to be openable and closable, the operator can It is possible to prepare for clogging of the used water spray nozzle 23 and the used spray nozzle 25 without having to carry the preliminary water spray nozzle 43 and the preliminary spray nozzle 45 at hand, and when the aircraft 1 is parked outdoors for a long time. However, it is possible to prevent water, dust, etc. from adhering to the pre-watering nozzle 43 and the pre-spraying nozzle 45.

The cooling fan 35 disposed in the engine room 7 generates wind W flowing in the engine room 7 in the longitudinal direction of the aircraft 1, and the mounting member 51 extends in the longitudinal direction of the aircraft 1. , the mounting member 51 to which the preliminary watering nozzle 43 and the preliminary spray nozzle 45 are attached is arranged in the engine room 7 without interfering with the wind W flowing in the longitudinal direction of the aircraft body 1 inside the engine room 7 by the cooling fan 35. I can do it.

Further, since the mounting member 51 is disposed on the frame 2 so as to be on the left side in the engine room 7, that is, on the outside in the left-right direction of the fuselage 1 perpendicular to the longitudinal direction of the fuselage 1, the cooling fan 35 The mounting member 51 can be provided at a position away from the mainstream of the wind W in which there is relatively little wind W flowing in the longitudinal direction of the aircraft body 1 in the room 7, and the wind W flowing in the longitudinal direction of the aircraft body 1 in the engine room 7 is further increased. The mounting member 51 to which the preliminary water spray nozzle 43 and the preliminary spray nozzle 45 are attached can be disposed in the engine room 7 without interfering with the engine room.

Furthermore, by disposing the mounting member 51 on the left side in the engine room 7, the operator can move the preliminary water nozzle 43 and the preliminary spray nozzle 45 attached to the mounting member 51 to the aircraft body when the engine cover 9 is opened. It can be easily attached and detached from the outside, especially from the left side of the fuselage.

The mounting member 51 is a flat plate member that is erected on the frame 2 at a position facing the side wall 9a of the engine cover 9 on the left side in the left-right direction in the engine room 7, and the preliminary water nozzle 43 and the preliminary spray nozzle 45 are Since the mounting member 51 is disposed on the surface facing the outside of the fuselage 1, dust contained in the wind W flowing in the engine room 7 by the cooling fan 35 does not hit the preliminary watering nozzle 43 and the preliminary spray nozzle 45. Therefore, clogging of the pre-watering nozzle 43 and the pre-spraying nozzle 45 due to dust or the like can be effectively suppressed.

The mounting portion 60 of the mounting member 51 made of a flat plate member is provided with a plurality of locking members 53 to which the preliminary watering nozzles 43 and the preliminary spraying nozzles 45 are attached, and the locking members 53 are arranged in rows L1 in the horizontal direction. , L2, and the number of locking members 53 included in the upper row L1 of the rows L1 and L2 is smaller than the number of locking members 53 included in the lower row L2, and Since the locking member 53 is located above between the adjacent locking members 53 of the lower row L2, the area of the upper side of the mounting member 51 formed to provide a plurality of locking members 53 is smaller than the area of the lower side. Thus, the inclined portions 65 can be provided on both the front and rear sides of the mounting portion 60. By making the area of the upper side of the mounting member 51 smaller than the area of the lower side, the mounting member 51 can be used to make the operator's work easier when the operator is servicing the drive device 13 etc. in the engine room 7. Disturbances can be reduced.

Furthermore, by positioning the locking member 53 included in the upper row L1 above between the adjacent locking members 53 in the lower row L2, the preliminary watering nozzle 43 and the preliminary spray nozzle 45 can be connected to the locking portion 75. When rotating the base 41 to lock or release the lock, the vertical height of the base 41 can be kept low while ensuring sufficient space for the knob 85 to rotate.

As parts related to compaction work, a used water sprinkling nozzle 23 and a used spray nozzle 25 for sprinkling water on the front wheels 3 are used, and as spare parts, a preliminary watering nozzle 43 and a spare are used as spare parts for the used water sprinkling nozzle 23 and the used spray nozzle 25. Since the spray nozzle 45 is used, spares of the water spray nozzle 23 and the spray nozzle 25, which are replaced particularly frequently, can be attached to the mounting member 51 and managed.

<Second embodiment>
The second embodiment will be described below based on FIG. 5. Note that descriptions of the configurations and effects common to the first embodiment will be omitted, and only portions that are different from the first embodiment will be described here.

Referring to FIG. 5, a diagram of the spare parts unit 140 and its surroundings according to the second embodiment as viewed from the front of the aircraft body is shown. The spare parts unit 140 according to the second embodiment is different from the spare parts unit 40 according to the first embodiment in that an upper plate member 147 is provided.

The upper plate member 147 is a flat plate member that extends from the side wall 9a of the engine cover 9 to the right in the left-right direction of the fuselage 1 and extends in the front-rear direction. When the engine cover 9 is in the closed state, the right end 147a of the upper plate member 147 is located on the right side above the mounting member 51. Further, the upper plate member 147 moves upward in conjunction with the engine cover 9 when the engine cover 9 is changed from the closed state to the open state.

As a result, in the spare parts unit 140, when the engine cover 9 is in the closed state, the preliminary water nozzle 43 and the preliminary spray nozzle 45 are covered from above by the upper plate member 147, and furthermore, the mounting member 51 and the cover 9 are connected to the left and right sides. By covering the pre-watering nozzle 43 and the pre-spray nozzle 45 from above and from the left and right, the spare parts unit 140 can more reliably cover the pre-watering nozzle including dust falling from above. 43 and the pre-spray nozzle 45 can be protected. Further, the upper plate member 147 moves upward in conjunction with the engine cover 9 when the engine cover 9 is opened from the closed state. Therefore, when the operator locks and disengages the pre-watering nozzle 43 and the pre-spray nozzle 45 from the mounting member 51, the upper plate member 147 does not get in the way, and the operator can perform the work easily.

As described above, in the compaction machine according to the second embodiment, the engine cover 9 includes the upper plate member 147 that covers the preliminary water spray nozzle 43 and the preliminary spray nozzle 45 from above when the engine cover 9 is in the closed state. , it is possible to further suppress dust contained in the wind W flowing in the engine room 7 from falling on the preliminary water nozzle 43 and the preliminary spray nozzle 45 when the engine cover 9 is in the closed state. can.

In particular, the mounting member 51 is disposed on the left side in the engine room 7, and the preliminary watering nozzle 43 and the preliminary spray nozzle 45 are disposed on the left side of the mounting member 51, so that the side wall 9a of the engine cover 9, the mounting member 51 and the upper plate member 147 can cover the preliminary watering nozzle 43 and the preliminary spray nozzle 45 from the left-right direction and the vertical direction of the body 1.

<Third embodiment>
The third embodiment will be described below based on FIG. 6. Note that descriptions of the configurations and effects common to the second embodiment will be omitted, and only portions that are different from the second embodiment will be described here.

Referring to FIG. 6, there is shown a perspective view of the spare parts unit 240 according to the third embodiment, viewed from the front upper left. The spare parts unit 240 according to the third embodiment is different from the spare parts unit 40 according to the first embodiment and the spare parts unit 140 according to the second embodiment in that a guard (windbreak plate) 265 is formed on the mounting member 251. They differ in that they are

The guard 265 is a flat plate portion extending leftward in the left-right direction from the front end of the attachment member 251 in the longitudinal direction of the body 1, and is formed by bending the front side of the attachment member 251. In other words, the guard 265 is configured to extend from the end of the mounting member 251 on the upstream side of the wind W to the side where the preliminary watering nozzle 43 and the preliminary spray nozzle 45 are provided. The left end 265a of the guard 265 extends to the vicinity of the side wall 9a of the engine cover 9 (see FIG. 5).

As a result, in the spare parts unit 240, the guard 265 extending from the upstream end of the wind W of the mounting member 251 toward the preliminary watering nozzle 43 side and the preliminary spray nozzle 45 side is formed, so that the preliminary watering nozzle 43 And, without directly exposing the preliminary spray nozzle 45 to dust contained in the wind W, it is possible to suppress dust from adhering to the preliminary watering nozzle 43 and the preliminary spray nozzle 45. Further, as described in the second embodiment, by covering the preliminary water spray nozzle 43 and the preliminary spray nozzle 45 with the upper plate member 147, the side wall 9a of the engine cover 9, the mounting member 251, and the upper plate member 147 can cover the preliminary water spray nozzle. 43 and the preliminary spray nozzle 45 can be covered from the left and right and up and down directions of the machine body 1, and further covered by the guard 265 from the front side in the longitudinal direction of the machine body 1, so that dust and the like can be better removed from the preliminary water spray nozzle 43 and the preliminary spray nozzle 45. can be prevented from adhering to.

As explained above, in the compaction machine according to the third embodiment, the attachment member 251 is located at the upstream side of the wind W flowing in the longitudinal direction of the machine body 1, and the preliminary watering nozzle 43 side and the preliminary spray nozzle 45 side. Since the extending guard 265 is provided, dust contained in the wind W flowing in the engine room 7 by the cooling fan 35 can be suppressed from adhering to the preliminary water spray nozzle 43 and the preliminary spray nozzle 45. Note that in the third embodiment, changes to the second embodiment have been described, but a guard 265 may be formed on the mounting member 51 of the first embodiment.

<Fourth embodiment>
The fourth embodiment will be described below based on FIG. 7. Note that descriptions of the configurations and effects common to the first embodiment will be omitted, and only portions that are different from the first embodiment will be described here.

Referring to FIG. 7, a front view of a spare parts unit 340 according to a fourth embodiment is shown. The spare parts unit 340 according to the fourth embodiment mainly differs from the spare parts unit 40 according to the first embodiment in the arrangement and attachment of the locking member 353, the preliminary watering nozzle 43, and the preliminary spray nozzle 45 in the upper row L1. The positions of the upper end 351a of the member 351 and the inclined portion 365 on the rear side in the longitudinal direction of the body 1 are different.

The locking member 353 of the upper row L1 according to the fourth embodiment is located at the front in the longitudinal direction of the fuselage 1 and lower in the vertical direction compared to the locking member 53 in the upper row L1 according to the first embodiment. . Here, the rotation range S of the knob 85 when attaching and detaching the preliminary watering nozzle 43 and the preliminary spray nozzle 45 to and from the locking member 353 is, for example, the rotation range S of the knob 85 when the preliminary watering nozzle 43 and the preliminary spraying nozzle 45 are held in a horizontal state. This is the range in which the knob 85 rotates when rotated clockwise by 45 degrees when viewed from the page 7.

The rotation range S of this knob 85 is, for example, upward from the horizontal on the front side and downward from the horizontal on the rear side. In other words, the lower front side and upper rear side of the knob 85 are outside the rotation range S. Therefore, in the fourth embodiment, compared to the locking member 53 of the upper row L1 according to the first embodiment, the locking member 353 of the upper row L1 is set to the front lower side of the locking member 53 of the lower row L2. It can be brought close to the locking member 53.

Therefore, while the locking members 53 and 353 are positioned so that the rotation ranges S when attaching and detaching the preliminary watering nozzle 43 and the preliminary spray nozzle 45 to and from the locking member 353 do not overlap with each other, the locking member 353 is operated in the first embodiment. By locating the upper end 351a of the mounting member 351 and the inclined portion 365 on the rear side in the longitudinal direction of the fuselage 1, the positions of the upper end 351a of the mounting member 351 and the inclined portion 365 on the rear side in the longitudinal direction of the fuselage 1 can be changed from those of the first embodiment by locating the upper end 351a of the mounting member 351 and the inclined portion 365 on the rear side in the longitudinal direction of the fuselage 1. It can be located on the lower side and the front side in comparison. Thereby, the mounting member 351 according to the fourth embodiment can be formed smaller than the mounting member 51 according to the first embodiment.

This completes the explanation of the rolling press according to the present invention, but the present invention is not limited to the above embodiments, and can be modified without departing from the gist of the invention.
For example, in this embodiment, the case where the rolling machine is a tire roller has been described as an example, but the rolling machine may be another rolling machine such as a macadam roller or a small vibrating roller.

Furthermore, in this embodiment, the spare parts are the preliminary watering nozzle 43 and the preliminary spray nozzle 45, and the spare parts units 40, 140, and 240 to which the preliminary watering nozzle 43 and the preliminary spray nozzle 45 can be attached and detached have been described. It may also be a brush, scraper, etc. that removes dirt and the like attached to the front wheels 3 and rear wheels 5, and the spare parts unit may be configured to be able to attach these.

Further, in the third embodiment, the guard 265 is provided so as to extend from the front end of the mounting member 251, but the guard may be provided so as to extend from the side wall 9a of the engine cover 9 toward the front end of the mounting member 251.
