Description

  The present invention relates to a rolling machine used for road surface paving work, and more particularly to a structure of a water storage tank that stores water used for watering a rolling roller and watering the road surface after rolling.

  In general, when pavement work is performed on a road surface, a rolling machine such as a vibration roller vehicle or a tire roller vehicle is used. This type of compaction machine is equipped with a compaction roller that also serves as a wheel on the front and rear sides of the vehicle body, and the pavement material is compacted by the compaction roller while running on a road surface paved with a paving material such as an asphalt mixture. Hereinafter, this operation is referred to as rolling). During pavement construction, water spraying to the rolling roller for the purpose of preventing adhesion of paving material to the rolling roller, or water spraying to the road surface for the purpose of promoting cooling and hardening of the road surface after rolling is performed. A large amount of water used for these applications is stored in a water storage tank provided in the compaction machine.

  Since the water stored in the water storage tank is supplied to the nozzle installed at a predetermined position on the vehicle body through the pipe and is used for water spraying to the rolling roller and the road surface, the installation location of the water storage tank on the vehicle body is For example, the degree of freedom is high compared to a mechanical configuration such as a power train. For this reason, the layout of the power train or the like is usually determined in preference, and the installation position of the water storage tank is determined from the surplus space. For example, in the technique described in Patent Document 1, the rear rolling roller of the vehicle body is determined. A water storage tank is installed directly above.

Japanese Patent Laid-Open No. 10-82014

  However, in the technique of the above-mentioned Patent Document 1, as shown in FIG. 1, since the water storage tank is located on the vehicle body so that it is difficult to replenish water by being installed directly above the rear rolling roller. Has occurred. In other words, tap water, river water, pond water, etc. are used as water to be supplied to the water storage tank. In any case, water supplied from the water tap or pump is supplied through the hose. It is carried out by pouring into the water inlet. However, since the water tank itself is installed at a high position and the water supply port is provided at the top of the water storage tank, the water supply port is very high for the worker, especially for small workers. However, even if it was visible, the tip of the hose could barely reach the water supply port. For this reason, the water discharged from the hose cannot be determined well at the water supply port, and the water that has deviated from the water supply port rebounds on the surface of the water storage tank and falls on the worker. Was very difficult to perform and was also a work with discomfort.

  In order to facilitate water injection to the water supply port, there are measures to enlarge the water supply port of the water storage tank or open the water supply port diagonally sideways. It cannot be completely prevented from escaping. In addition, there is a measure to provide a step directly under the water storage tank of the compaction machine in order to improve the accessibility to the water supply port. However, the addition of the step increases the cost, and the step protruding to the side of the vehicle body May worsen the handling of the rolling machine. Therefore, a drastic countermeasure has been demanded conventionally.

  The present invention has been made to solve such problems, and the object of the present invention is to cause problems such as cost increase even when the water storage tank is installed at a high position on the vehicle body. To provide a water storage tank structure for a rolling compaction machine that can prevent the situation where water poured from a hose or the like deviates from the water supply port and falls to the worker, and can easily perform water replenishment work. It is in.

  In order to achieve the above object, a first aspect of the present invention is to provide a water storage tank installed on the airframe and provided with a water supply port at the top, and a rolling roller or road surface provided in the airframe with water stored in the water storage tank. In a rolling compactor equipped with water spray means for spraying water on at least one side, a drainage groove is recessed on the surface of the water storage tank so as to surround the water supply port, and the drainage groove is extended downward to penetrate the frame of the fuselage. A water repellency preventing member is provided in the water storage tank so as to communicate with the lower part of the machine body through the drainage port provided and to correspond to at least the periphery of the water supply port of the drainage groove.

  Therefore, when water is supplied to the water supply port of the water storage tank by a hose or the like, the water that has escaped from the water supply port collides with the surrounding water splash preventing member and is prevented from being rebounded, and then guided inside the drainage groove to be discharged to the discharge port. Is discharged to the lower part of the aircraft. Therefore, even if water deviates from the water supply port, it is possible to prevent the worker from getting down, and since it is not always necessary to pour all the water into the water supply port, the water supply operation can be easily performed.

The invention according to claim 2 is a water-absorbing sheet in which the water repellency preventing member allows water to permeate therein, and is disposed in the drainage groove.
Therefore, the water that has escaped from the water supply port permeates the water absorbing sheet and is prevented from rebounding.
The invention according to claim 3 is a mesh panel in which the water splash preventing member is deenergized while allowing water to permeate, and is disposed on the surface of the water storage tank so as to cover the drainage groove and between the bottom surface of the drainage groove. The gap is formed.

Therefore, the water that has escaped from the water supply port is extinguished when passing through the mesh panel, and rebounding at the bottom surface of the drainage groove is prevented.
According to a fourth aspect of the present invention, the water storage tank is accommodated in a tank accommodating portion provided in the frame of the fuselage, and the upper portion of the tank is in a state where the bottom surface and one side surface are in contact with the bottom surface and one side surface in the tank accommodating portion. The drainage groove is protruded upward from the storage portion, and extends from the periphery of the water supply port of the water storage tank to the bottom surface through one side surface, and is closed by the bottom surface and one side surface of the tank storage portion. A passage extending to a drain outlet penetrating the bottom surface is formed, and a water splash preventing member is disposed in a portion exposed to the outside from the tank housing portion of the drain groove.

Accordingly, since the drainage groove is closed on the bottom surface and one side surface of the tank housing portion on the lower side of the water splash preventing member, the water storage tank has a closed cross-sectional shape that is difficult to remove. Instead of this, it is only necessary to provide a recessed drainage groove with an open cross-sectional shape that is easy to punch out, and the water storage tank can be easily formed.
According to a fifth aspect of the present invention, the tank accommodating portion is positioned above the rear pressure roller provided at the rear of the fuselage, the drainage port on the bottom surface of the tank accommodating portion is directly above the rear pressure roller, and the rear pressure is reduced. It is located on the opposite side of the worker's standing position when water is supplied to the water supply port across the roller shaft.

  Accordingly, the water discharged from the drainage port falls on the rear rolling roller and falls on the road surface opposite to the standing position of the worker who is replenishing water along the outer circumferential surface of the rear rolling roller. . For this reason, not only the water that has deviated from the water supply port is prevented from falling on the worker, but also the operator's feet are not wetted by the water discharged from the drain port.

  As described above, according to the water storage tank structure of the compaction machine according to the first aspect of the present invention, the water splash preventing member is disposed around the water supply port of the water storage tank to prevent the water splashing off the water supply port. Since it is discharged from the discharge port to the lower part of the fuselage through the guide groove, a hose etc. can be used even if the water storage tank is installed at a high position of the fuselage, avoiding adverse effects such as cost increase Thus, it is possible to prevent the situation where the water poured from the water deviates from the water supply port and falls on the worker, so that the water supply operation can be easily performed.

According to the water storage tank structure of the rolling machine of the second aspect of the invention, in addition to the first aspect, the water-absorbing sheet that permeates water can surely prevent the water from rebounding.
According to the water storage tank structure of the rolling machine of the third aspect of the invention, in addition to the first aspect, the rebounding of the water can be reliably prevented by the mesh panel that is deenergized while allowing the water to permeate.
According to the water storage tank structure of the rolling compaction machine of the invention of claim 4, in addition to claim 1, the water storage tank is formed by closing the drainage groove on the bottom surface and one side surface of the tank housing portion to function as a passage. Can be easily implemented, and as a result, the manufacturing cost can be reduced.

  According to the water storage tank structure of the rolling machine of the fifth aspect of the invention, in addition to the fourth aspect, the water discharged from the drainage port is transferred along the outer peripheral surface of the rolling pressure roller so that the operator's feet get wet. This prevents the water from being replenished more comfortably.

[First Embodiment]
Hereinafter, a first embodiment in which the present invention is embodied in a water storage tank structure of a vibration roller will be described.
FIG. 1 is a front view showing the vibration roller of this embodiment, and FIG. 2 is a side view of the vibration roller as seen from the rear.
The vehicle body of the vibration roller is composed of a front vehicle body 2 having a front roller roller 1 and a rear vehicle body 4 having a rear roller roller 3, and the front vehicle body 2 and the rear vehicle body 4 are center pins. 5 are connected in an articulated manner that can be bent in the horizontal direction, and the vehicle is turned by bending each other. The front rolling roller 1 is composed of a metal drum having a length substantially corresponding to the vehicle width, and is rotatably supported by a pair of left and right support arms 6 extending downward from the front vehicle body 2. The rear rolling roller 3 is composed of a total of four rubber tires, left and right, and is rotatably supported by an axle 7 provided on the rear vehicle body 4.

  The front vehicle body 2 is equipped with devices such as an engine and a hydraulic pump as a power unit. Although not shown, the hydraulic oil discharged from the hydraulic pump by driving the engine includes a traveling motor connected to the axle 7 and a front portion. It is supplied to a vibration motor provided in the rolling roller 1. When the hydraulic oil is supplied, the traveling motor rotates the front roller 1 and the rear roller 3 to drive the vibration roller, and the vibration motor vibrates the front roller 1 when rolling the road surface. To do.

An operation console 9 having a steering 8 is installed at a front position on the rear vehicle body 4, and a seat 10 is installed on the rear side of the operation console 9. An operator seated on the seat 10 runs the vibration roller by operating the steering 8 and the accelerator pedal or the brake pedal under the foot, and performs rolling of the road surface by the front portion 1 and the rear rolling roller 3 during pavement work.
The vehicle body frame 12 constituting the rear vehicle body 4 forms a box-shaped tank housing portion 13 directly below and behind the seat 10, and the tank housing portion 13 opens upward on the rear side of the seat 10, The bottom surface 13 a is positioned on the rear rolling roller 3. As will be described in detail later, a water storage tank 14 is installed in the tank housing portion 13. ) Are connected via a pipe and a water supply pump. Water is stored in the water storage tank 14, and water in the water storage tank 14 is supplied to each sprinkling nozzle by a water supply pump for the purpose of preventing the pavement material from adhering to the front and rear rolling rollers 1 and 3 during pavement work. Water is sprayed onto the rollers 1 and 3 and the road surface.

Note that reference numeral 16 in FIG. 2 denotes lights including a direction indicator and a brake lamp.
Next, the structure of the water storage tank 14 which is a characteristic part of the present invention will be described.
3 is a partial plan view showing the water storage tank of the vibration roller, FIG. 4 is a partial side view showing the water storage tank, FIG. 5 is a cross-sectional view taken along the line V-V of FIG. It is the VI-VI sectional view taken on the line of FIG. 4 which shows the fixed location of a tank.

  As shown in FIGS. 3 to 5, the water storage tank 14 basically has a rectangular parallelepiped shape corresponding to the opening of the tank housing portion 13 and is disposed in the tank housing portion 13. It protrudes and is located behind the seat 10. A buffering rubber 21 is bonded to the bottom surface 13a and the rear surface 13b in the tank housing portion 13, and the bottom surface 14a of the water storage tank 14 abuts against the bottom surface 13a of the tank housing portion 13 via these rubbers 21, thereby storing the water. The rear surface 14 b (one side surface) of the tank 14 is in contact with the rear surface 13 b (one side surface) of the tank housing portion 13. In the tank accommodating part 13, the lower part of the water storage tank 14 is extended toward the front to form an extending part 14c. As a result, the dead space of the tank accommodating part 13 directly under the seat 10 is formed by the extending part 14c. It is effectively used to increase the amount.

  Two regulating pieces 22 are welded to the bottom surface 13a of the tank housing portion 13 at intervals on the left and right sides, and these regulating pieces 22 abut against the left and right sides of the water storage tank 14 to regulate the movement in the left and right directions. Yes. A bracket 23 is fixed to the bottom surface of the tank housing portion 13 with bolts 23a and nuts 23b. The bracket 23 abuts against the extended portion 14c of the water storage tank 14 from the front and is located between the rear surface 13b of the tank housing portion 13 and the rear surface 13b. Thus, the movement of the water storage tank 14 in the front-rear direction is restricted, and the upper end of the bracket 23 bent backward is brought into contact with the extending portion 14c from above to prevent the water tank 14 from floating. As shown in FIGS. 4 and 6, a pair of brackets 24 are fixed to the rear surface 13b of the tank housing portion 13 with bolts 24a and nuts 24b with a space left and right, and the upper end of the bracket 24 bent forward is the water storage tank. 14 is brought into contact with a latching portion 14d provided in a recessed manner on the rear surface 14b of the rear surface 14b from above so as to prevent lifting. With the above configuration, the water storage tank 14 is fixed in the tank housing portion 13.

  A water supply port 25 having a detachable cap 25a is provided on the upper surface 14e of the water storage tank 14, and as shown in FIG. 2, the horizontal position of the water supply port 25 is offset to the left with respect to the vehicle body center. . A drainage groove 26 having a predetermined depth is formed in the upper surface 14e of the water storage tank 14 so as to surround the water supply port 25, and the drainage groove 26 extends rearward on the upper surface 14e of the water storage tank 14 as shown in FIG. The rear surface 14b is extended to the bottom surface 14a. The upper surface 14e of the water storage tank 14 is slightly inclined so as to be lowered rearward, and the bottom surface 26a in the drain groove 26 is also inclined at the same angle. The water storage tank 14 is manufactured by blow molding using a thermoplastic resin as a material. At this time, the water supply port 25 and the drainage groove 26 are also integrally formed. However, the manufacturing method of the water storage tank 14 is not limited to this, and the type and forming method of the resin material may be changed, or a part obtained by press forming a steel plate may be welded and manufactured.

  As shown in FIGS. 2 and 4, the left and right width of the drainage groove 26 is maintained at a constant width at a portion exposed to the outside from the tank accommodating portion 13 of the upper surface 14 e and the rear surface 14 b of the water storage tank 14, and rapidly decreases below the drainage groove 26. After that, it extends to the bottom surface 14a with a constant width. A drain hole 27 (drain port) is formed through the bottom surface 14 a of the water storage tank 14 and the bottom surface 13 a of the tank housing portion 13 so as to correspond to the drainage groove 26. It communicates with the pressure roller 3 side. As shown in FIG. 4, the drain hole 72 is located immediately above the left inner ring of the rear rolling roller 3 in the left-right direction, and more than the axial center C of the rear rolling roller 3 in the front-rear direction as shown in FIG. It is located on the front side by the offset amount α, in other words, on the opposite side of the operator's standing position when performing the water replenishment operation across the axis C.

  A water absorbing sheet 28 (water repellent prevention member) is disposed in the drain groove 26 at a wide portion extending from the upper surface 14 e to the rear surface 14 b of the water storage tank 14. The water absorption sheet 28 has a shape corresponding to the drainage groove 26 as shown in FIGS. 3 and 4, and is bent at a substantially right angle corresponding to the upper surface 14e and the bottom surface 14b of the water storage tank 14 as shown in a side view of FIG. The engaging hole 28 a penetrating in the upper part is fitted into the water supply port 25 so as to be held in the drainage groove 26. The thickness of the water absorbent sheet 28 is slightly thinner than the depth of the drainage groove 26, and the lower end of the water absorbent sheet 28 is inserted between the bottom surface 26 a of the drainage groove 26 and the rear surface 13 b of the tank housing portion 13 from above. The fixing of the water absorbing sheet 28 is not limited to this. For example, the water absorbing sheet 28 may be bonded to the bottom surface 26a of the drainage groove 26 with an adhesive.

As a result, the entire portion of the drainage groove 26 from the water supply port 25 to the drain hole 27 that is exposed to the outside from the tank housing portion 13 is covered with the water absorbent sheet 28, and the lower portion of the drain housing 26 is covered with the tank housing portion 13. A passage extending to the drain hole 27 is formed by being blocked by the inner surface (the rear surface 13a and the bottom surface 13b).
The water absorbent sheet 28 of the present embodiment is made of a material having a high water absorption, for example, a sponge. However, the material of the water absorbing sheet 28 is not limited to this, and for example, a cloth woven with hemp or the like, or a nonwoven fabric may be used. Further, as will be apparent from the following description, the action of the water absorbing sheet 28 is to impinge the collided water into the inside and suppress the rebound, so that it has a certain thickness as in the present embodiment. Is desirable.

Next, the operation of the water storage tank structure of the vibration roller configured as described above will be described.
As described above, water is supplied to the water storage tank 14 prior to the construction in order to perform watering from the roller water spray nozzle 15 and the road surface water spray nozzle to the rollers 1 and 3 and the road surface after rolling. The Water supply is performed by pouring water from the hose into the water supply port 25 of the water storage tank 14. As is apparent from FIG. 1, the water storage tank 14 itself is installed at a high position on the rear rolling roller 3. In addition, the water supply port 25 is provided at the top of the water storage tank 14. For this reason, in the technique of Patent Document 1 described as the prior art, the water that has come out of the hose cannot be well defined in the water supply port 25, and the water that has escaped from the water supply port 25 falls on the operator. . Therefore, instead of preventing the water from the hose from escaping from the water supply port 25 as in the conventional measures, the problem is solved by preventing the water deviated from the water supply port 25 from falling on the operator. This is the embodiment.

  That is, although water from the hose may escape from the water supply port 25, the diverted water collides with the water absorption sheet 28 around the water supply port 25, and the water absorption sheet 28 made of sponge does not repel the collided water. Infiltrate. The water that has permeated the water absorbent sheet 28 is guided to the drainage groove 26, moves downward so as to follow the inclination of the bottom surface 26 a, then moves downward, and drops into the drainage groove 26 from the lower end of the water absorbent sheet 28. The dropped water moves downward in the drainage groove 26 closed by the inner surface of the tank housing portion 13 and then moves forward, and is discharged downward through the drain hole 27 and onto the left inner ring of the rear roller 3. Fall. Since the drop position at this time is the front side of the axis C, the water travels along the outer peripheral surface of the rear rolling roller 3 and is on the road surface ahead, that is, the standing position of the worker who is replenishing water. Falls on the opposite road surface.

  For this reason, it is possible to prevent a situation where water deviated from the water supply port 25 falls on the worker, and also the water discharged from the drain hole 27 does not wet the operator's feet, resulting in water replenishment work. Can be carried out comfortably. In particular, in the vibrating roller as in the present embodiment, the outer peripheral surface of the rear rolling roller 3 has a rectangular cross section for the purpose of rolling the road surface, so that the outer peripheral surface is transmitted as compared with a tire having a normal arc cross section. The water does not easily escape to the left and right, and the above effect can be obtained by reliably guiding the water on the road surface ahead.

  Further, even if the water deviates from the water supply port 25 in this way, there is no influence on the operator, and therefore it is not always necessary to pour all the water into the water supply port 25. Therefore, the conventional work such as changing the shape of the water supply port 25 or increasing the number of steps is unnecessary, and even if the water supply port 25 of the water storage tank 14 is at a high position for the worker, the water supply operation is extremely difficult. It can be easily implemented.

Further, below the lower end of the water absorbent sheet 28, the drainage groove 26 is closed by the rear surface 13 a and the bottom surface 13 b of the tank housing portion 13 to function as a passage. For this reason, the water storage tank 14 does not need to be provided with a closed cross-sectional passage that is difficult to remove for guiding water, and is instead provided with a drain groove 26 that has an open cross-sectional shape and can be easily removed. Just do it. Therefore, the water storage tank 14 can be molded by a simple molding method such as blow molding, and the manufacturing cost can be reduced.
[Second Embodiment]
Next, a second embodiment in which the present invention is embodied in a water tank structure of another vibration roller will be described.

The basic configuration of the vibrating roller of the present embodiment is the same as that described in the first embodiment, and the difference is in the structure around the water storage tank 14. Therefore, the same member numbers are assigned to the components having the same configuration, the description thereof is omitted, and differences will be described mainly.
FIG. 7 is a partial side view of the water storage tank 14 of the vibration roller of this embodiment as viewed from the rear, and FIG. 8 is a cross-sectional view taken along the line VIII-VIII of FIG. Also in the present embodiment, the shape of the water storage tank 14 including the drainage groove 26 and the state of installation in the tank housing portion 13 are the same as in the first embodiment, and the difference is the water absorbing sheet 28 of the first embodiment. Instead, a mesh panel 31 (water splash preventing member) is provided in the drainage groove 26.

  As described in the first embodiment, the drainage groove 26 is formed across the upper surface 14e, the rear surface 14b, and the bottom surface 14a of the water storage tank 14, and the portion of the drainage groove 26 exposed to the outside from the inside of the tank accommodating portion 18. A mesh panel 31 is disposed so as to cover. That is, the mesh panel 31 is bent at a substantially right angle corresponding to the upper surface 14e and the bottom surface 14b of the water storage tank 14 as shown in a side view of FIG. 8, and the front end and the left and right ends are stored in water as shown in FIGS. Overlaid on the surface of the tank 14.

  9 is a perspective view showing the mesh panel 31, FIG. 10 is an exploded perspective view showing the mesh panel 31, and FIG. 11 is a cross-sectional view taken along the line XI-XI in FIG. 7 showing the fixing location of the mesh panel 31 to the water storage tank 14. is there. The mesh panel 31 includes a surrounding frame body 32 and a net member 33 stretched on the frame body 32. The frame body 32 is made of a steel plate such as a PL material (SS400) or a stainless steel plate, and is pressed into a rectangular frame shape bent at a substantially right angle, and screw holes 32a for attachment are provided therethrough at predetermined intervals. In the case of steel materials, plating treatment or painting treatment is applied to prevent corrosion. The net member 33 is manufactured by plain weaving of a stainless steel wire, has a square shape slightly larger than the inside of the frame body 32, and has an escape hole 33a through which the water supply port 25 of the water storage tank 14 is inserted. ing. The mesh member 33 is spot welded at a predetermined interval with its periphery superimposed on the surface of the frame 31a (the welded portion is indicated by WD in FIG. 11).

  The mesh panel 31 configured as described above is disposed with the front end and the left and right ends of the frame body 32 overlapped on the surface of the water storage tank 14, and the water supply port 25 of the water storage tank 14 is formed by the mesh member 33 of the mesh panel 31. It protrudes upward through the escape hole 33a, and the cap 25a can be removed to supply water arbitrarily. As shown in FIG. 11, a thick portion 34 and a screw hole 35 are formed on the surface of the water storage tank 14 so as to correspond to each screw hole 32 a of the frame body 32, and each via the screw holes 32 a of the frame body 32. The mesh panel 31 is fixed to the surface of the water storage tank 14 by screwing the screws 36 into the screw holes 35.

  As a result, the portion of the drainage groove 26 exposed to the outside from the tank accommodating portion 13 is covered with the mesh material 33 of the mesh panel 31 except for the water supply port 25, and between the bottom surface 26 a of the drainage groove 26 and the mesh material 33. A gap L corresponding to the depth of the drainage groove 26 is formed. The lower end of the mesh panel 31 is inserted from above between the rear surface 14b of the water storage tank 14 and the rear surface 13b of the tank housing portion 13.

  In the present embodiment, the gap L between the bottom surface 26a of the drainage groove 26 and the net member 33 is set to 20 mm, and the horizontal interval Lx and the vertical interval Ly of each wire constituting the net member 33 are both in the range of 1 to 3 mm. Is set in. As will be apparent from the following description, the action of the mesh panel 31 is to deenergize while allowing the water entering and exiting the drainage groove 26 to pass through. Each requirement L, Lx, Ly is set.

  Note that the configuration of the mesh panel 31 is not limited to the above, and can be arbitrarily changed as long as it has corrosion resistance and strength that can withstand the collision of the hose nozzle and the like. Therefore, for example, the mesh material 33 is twilled, the material is changed to a synthetic resin material, or the expanded metal formed by stitching the steel sheet with a staggered cut is formed as the material of the mesh material 33. You may do it. If the material has a certain degree of rigidity, such as expanded metal, the expanded metal itself may be directly fixed to the surface of the water storage tank without using the frame 32. Further, the requirements L, Lx, and Ly are not necessarily limited to the above and can be arbitrarily changed.

Next, the operation of the water storage tank structure of the vibration roller configured as described above will be described.
As in the first embodiment, this embodiment also has the idea of preventing the water from flowing away from the water supply port 25 and preventing the deviated water from falling on the operator, but prevents the water from falling down. The principle is different. That is, the water that has escaped from the water supply port 25 collides with the net member 33 of the surrounding mesh panel 31 and is deactivated when it flows through the countless stitches and flows into the drainage groove 26. For this reason, most of the water that has passed through the stitches does not rebound on the bottom surface 26 a of the drainage groove 26, and moves down to the drain hole 27 by being guided in the drainage groove 26 after following the inclination of the bottom surface 26 a as it is. After that, as described in the first embodiment, it travels along the outer peripheral surface of the rear rolling roller 3 and falls on the road surface opposite to the operator's standing position.

  On the other hand, although a part of the water that flows into the drainage groove 26 through the mesh member 33 of the mesh panel 31 rebounds at the bottom surface 26a, the momentum is weak, and even if it rebounds and reaches the mesh member 33, it is knitted again. Since it is further de-energized when passing through, it does not scatter to the outside and fall on the operator. As a result, all the water deviated from the water supply port 25 does not fall on the worker, does not wet the operator's feet, and can replenish the water comfortably, and the water from the hose is supplied to the water supply port. Since there is no problem even if it deviates from 25, the water supply operation can be carried out very easily.

  This is the end of the description of the embodiment. However, the embodiment of the present invention is not limited to this embodiment. For example, in each of the embodiments described above, the water tank structure of the vibration roller is embodied. However, the application target is not limited to this, and the rolling machine including the water tank 14 for watering the road surface and the pressure roller. Any change can be made. Therefore, for example, it may be embodied as a water tank structure of a tire roller or a Macadam roller. Needless to say, the mounting position of the water storage tank 14 is not limited to the above-described embodiments. For example, the water storage tank 14 may be mounted on the front vehicle body 2.

  In the first embodiment, the water absorbing sheet 28 is disposed in the drain groove 26 of the water storage tank 14, and in the second embodiment, the mesh panel 31 is disposed so as to cover the drain groove 26. The drainage groove 26 is not necessarily required and may be omitted. For example, in the first embodiment, the water absorption sheet 28 may be simply attached to the surface of the water storage tank 14 so as to surround the water supply port 25. In the second embodiment, a gap is formed on the surface of the water storage tank 14 via a spacer. The mesh panel 31 may be simply fixed in the formed state. However, as is apparent from the description of each embodiment, the drainage groove 26 is used to guide the water that has penetrated the water absorbent sheet 28 or the water that has passed through the stitches of the mesh panel 31 downward, so that the operator can get water. Therefore, the embodiment in which the drainage groove 26 is formed is most desirable.

  Further, in each of the above-described embodiments, water dripping from the lower end of the water absorbent sheet 28 or water flowing into the drainage groove 26 through the mesh panel 31 is passed from the drainage groove 26 through the drain hole 27 to the rear rolling roller 3. After being discharged upward, it is dropped onto the road surface along the outer peripheral surface of the rear rolling roller 3, but it is not always necessary to configure in this way. For example, water may be discharged directly from the drain hole 27 to the road surface, or the drainage groove 28 may be formed up to the lower end of the water absorbent sheet 28 or the mesh panel 31, and water may be discharged directly from the open end to the road surface. May be. In these cases, the water guiding action by the rear rolling roller 3 is not obtained, but since the water is guided downward by the drainage groove 26, it is possible to reliably prevent the operator from getting water.
