Description

[Technical field]

[0001] The present invention relates to a rolling machine equipped with a liquid agent spraying nozzle that sprays a liquid agent onto a rolling wheel, and a liquid agent tank that stores the liquid agent. [Background technology]

[0002] Conventionally, there is known a technology relating to a rolling machine equipped with a liquid agent spraying nozzle that sprays a liquid agent as an adhesion prevention agent to prevent paving materials such as asphalt from adhering to rolling wheels, and a liquid agent tank that stores the liquid agent. For example, Patent Document 1 describes a rolling machine in which the liquid agent tank is mounted on the rear of the vehicle body from the driver's seat. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6113109 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the configuration of Patent Document 1, the liquid agent tank is mounted on the rear of the vehicle body from the driver's seat, so the driver sitting in the driver's seat cannot check the amount of liquid agent stored in the liquid agent tank while driving unless he or she significantly changes their posture or line of sight, and in order to visually check the amount of stored liquid, the driver must climb onto the floor where the driver's seat is located, making it difficult to smoothly and easily check the amount of hydraulic oil during pre-start inspections, etc. As a result, it is possible that maintenance of the liquid agent cannot be performed appropriately, and that the liquid agent cannot be properly sprayed onto the rolling wheels.

[0005] The present invention has been made in consideration of such problems, and its object is to provide a rolling machine that makes it easy to check the amount of liquid stored in the liquid tank. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the rolling compaction machine of the present invention is a rolling compaction machine comprising a driver's seat, a front rolling wheel provided in front of the driver's seat, a liquid agent spraying nozzle for spraying a liquid agent onto the front rolling wheel, and a liquid agent tank for storing the liquid agent, wherein the liquid agent tank is provided above the front rolling wheel and is provided so that at least a portion of the liquid agent tank is exposed toward the driver's seat, and the portion of the liquid agent tank exposed toward the driver's seat includes a liquid level indicator that shows the liquid level of the liquid agent stored in the liquid agent tank.

[0009] [First embodiment] An embodiment of the present invention will be described below with reference to the drawings. Fig. 1 is a perspective view showing a tire roller as a rolling machine of the first embodiment. Fig. 2 is a right side view showing the tire roller, and Fig. 3 is a plan view showing the tire roller. In the following description, the vehicle front-rear direction, left-right direction (i.e., vehicle width direction), and up-down direction are defined with reference to a driver riding on the tire roller 1.

[0010] Three rubber front rolling wheels 3f (rolling wheels) that also serve as running wheels are arranged in parallel in the left-right direction at the front of the body 2 of the tire roller 1, and are supported by the body 2 via a yoke 3 so as to be steerable. In addition, four rubber rear rolling wheels 3r that also serve as running wheels are arranged in parallel in the left-right direction at the rear of the body 2, and are supported by the body 2 via axles (not shown).

[0011] On the right side of the vehicle body 2, approximately in the center in the vehicle front-rear direction, a floor 4 is formed by a floor plate, and on the left side, a step-like step 5 is formed by cutting out the left side of the vehicle body 2, and an operator can get on and off the vehicle body 2 via the step 5. An operating console 8 equipped with a steering wheel 6 and a forward / reverse lever 7 is installed on the front side of the floor 4, and a driver's seat 9 is installed on the rear side. A water supply pump 10 is installed adjacent to the left side of the driver's seat 9, and a ladder 11 is installed on the right side of the driver's seat 9. A roof 13 is supported directly above the driver's seat 9 via a roof stand 12, and the above forms a driver's cab 14 on the right side of the vehicle body 2. The operator seated in the driver's seat 9 operates the steering wheel 6, the forward / reverse lever 7, and the pedal 15 on the floor 4 to run the tire roller 1, and during paving work, the front rolling wheels 3f and the rear rolling wheels 3r compact the paving material laid on the road surface. The water supply pump 10 is also used when replenishing water to a water storage tank 24 (see the shaded area in FIG. 2) from a nearby pond, river, or the like.

[0012] A water sprinkler nozzle 17 and a liquid agent spray nozzle 18 are provided near the top of the front roller 3f and the rear roller 3r, respectively, and are connected to a water storage tank 24 and a liquid agent tank 60 provided in the vehicle body 2, respectively. Although not shown, three water storage tanks 24 are provided in the vehicle body 2 in a line in the vehicle width direction. During paving work, in order to prevent adhesion of paving material or mud to the outer peripheral surfaces of the front roller 3f and the rear roller 3r, water stored in the water storage tank 24 is sprayed from the water sprinkler nozzle 17 to the upper part of each outer peripheral surface, or a liquid agent (solvent) that is an adhesion prevention agent stored in the liquid agent tank 60 (schematically shown in Figs. 2 and 3) is sprayed from the liquid agent spray nozzle 18. This prevents part of the paving material from adhering to the front roller 3f and the rear roller 3r.

[0013] An engine room 20 equipped with an openable / closable engine hood 19 is defined in front of the operation console 8 on the vehicle body 2, and although not shown, an HST (Hydro Static Transmission) is mounted inside the engine room 20. Since the configuration of the HST is well known, only an outline will be described; it is a hydraulic system that uses hydraulic oil from a hydraulic pump driven by the engine to drive hydraulic actuators of various hydraulic devices installed in various parts of the vehicle body 2. This HST drives the rear rolling wheels 3r and steers the front rolling wheels 3f.

[0014] The vehicle body 2 has fender shields 25, 26 that cover the left and right front rolling wheels 3f from above. The fender shield 25 is attached to the right side surface 20a of the engine room 20, and the fender shield 26 is attached to the left side surface 20b of the engine room 20. The right fender shield 25 is provided with a liquid agent tank 60, and a headlight 23 is provided in front of it. A gap S (FIG. 2) is formed between the front rolling wheel 3f and the right fender shield 25 so that the liquid agent spray nozzle 18 is exposed toward the driver's seat 9. Furthermore, an opening 21 is formed between the right fender shield 25 and the vehicle body 2 in front of the driver's seat 9 on the vehicle body 2 to ensure visibility for the operator. The opening 21 is formed by dividing the right side of the engine room 20 of the vehicle body 2 into front and rear parts, and the divided front structure becomes the fender shield 25. The left side of opening 21 is defined by the right side surface of engine compartment 20, the rear side of opening 21 is defined by an inclined cutout surface 2a formed in vehicle body 2, the front side of opening 21 is defined by the lower part of fender shield 25, and the right side of opening 21 is open to the right.

[0015] The opening 21 communicates the driver's seat 9 side with the back surface 60a of the liquid tank 60, and also communicates the driver's seat 9 side with the gap S between the right front rolling wheel 3f and the fender shield 25. As a result, as shown by the solid arrow in FIG. 2, the driver sitting in the driver's seat 9 can visually check the back surface 60a of the liquid tank 60 and the gap S between the front rolling wheel 3f and the fender shield 25 from the eye point P. As a result, the driver can visually check the situation around the upper part of the front rolling wheel 3f through the opening 21, for example, the state of adhesion of paving material and mud to the outer peripheral surface of the front rolling wheel 3f, and the state of spraying of water and solvent from each nozzle 17, 18. In addition, the degree of wetness of the outer peripheral surface of the front rolling wheel 3f can be visually checked, so that it is possible to judge whether water is being sprayed or not based on the degree of wetness.

[0016] The front roller 3f that the operator can see is limited to the rightmost one, but the state of adhesion of paving material and mud to all the front rollers 3f can be considered to be approximately equal. In addition, since the circuits of the water spray nozzles 17 of each front roller 3f are the same system, the water spraying state can be considered to be approximately equal, and similarly, since the circuits of the liquid spray nozzles 18 are the same system, the solvent spraying state can be considered to be approximately equal. Therefore, by visually checking the rightmost front roller 3f, the status of the other front rollers 3f can also be grasped.

[0017] Next, the configurations of the right fender shield 25 and the liquid tank 60 will be described with reference to Figs. 4 to 7. Fig. 4 is an exploded perspective view showing the liquid tank of the first embodiment. Fig. 5 is a perspective view of the vicinity of the fender shield 25 of the pneumatic tire roller 1, viewed from the front right side and above. Fig. 6 is a perspective view showing the attached state of the liquid tank 60 of the first embodiment. Fig. 7 is a perspective view of the pneumatic tire roller 1, viewed from the rear right side. Fig. 8 is a perspective view of the pneumatic tire roller 1, viewed from the rear side and above.

[0018] The fender shield 25 includes a bracket 30, a tank body 40, and a cover 50. The bracket 30 is a frame body formed of a metal material and having a U-shaped cross section, which has a front plate 31 and side plates 32 and 33. The front plate 31 forms the front surface of the fender shield 25. The front plate 31 is formed with an opening 31a for attaching the headlight 23. The side plates 32 and 33 are arranged opposite each other and extend rearward from both ends of the front plate 31 in the vehicle width direction. One side plate 32 is fastened to the right side surface 20a forming the engine room 20 of the vehicle body 2 by using bolts and nuts. A space is formed between the front plate 31 of the bracket 30 and the tank body 40. The lower surface of the space is not closed, and an operator can use this space to attach the headlight 23 or perform maintenance on the liquid agent tank 60.

[0019] The tank body 40 is formed of a metal material and has a front plate 41, an upper plate 42, a lower plate 43 (FIG. 7), and a rear plate 44. The tank body 40 is disposed between the side plates 32, 33 of the bracket 30, and is joined to the side plates 32, 33 at both ends in the vehicle width direction. As a result, the space surrounded by the side plates 32, 33 and the tank body 40 becomes a storage space for storing the liquid agent. Therefore, the liquid agent tank 60 is composed of the side plates 32, 33 of the bracket 30 and the tank body 40. The upper plate 42 of the tank body 40 is provided with a liquid agent supply port 45 for supplying the liquid agent into the liquid agent tank 60, and a detachable cap 47 is attached to the liquid agent supply port 45.

[0020] In addition, the liquid agent spraying pump 62 is attached to the front plate 41 of the tank body 40 by bolt fastening via a flat plate-shaped mounting member 46. This makes it possible to save space in the engine room 20 compared to the case where the liquid agent spraying pump 62 is provided in the engine room 20. The liquid agent spraying pump 62 is an electric pump for supplying the liquid agent stored in the liquid agent tank 60 to the liquid agent spraying nozzle 18, and is connected to a power source (not shown) mounted on the vehicle body 2. As shown in FIG. 6, the liquid agent spraying pump 62 has a suction hose 63 connected to the inside of the liquid agent tank 60 and pumps up the liquid agent in the liquid agent tank 60. In addition, the liquid agent spraying pump 62 has a discharge hose 64 extended into the engine room 20 via the side plate 32 of the bracket 30 and the right side surface 20a of the engine room 20, and is connected to a circuit for spraying the liquid agent arranged in the engine room 20. In addition, in the above circuit, a switching solenoid valve provided between the liquid agent spraying pump 62 and the liquid agent spraying nozzle 18, a drain device for discharging the liquid agent to the outside, etc. are arranged. As a result, the liquid agent pumped up from the liquid agent spraying pump 62 is supplied to the liquid agent spraying nozzle 18 via the above circuit.

[0021] As shown in Fig. 5, the cover 50 has an upper surface portion 51 and a side surface portion 52 made of a metal material, and is an L-shaped cross-sectional cover that covers the bracket 30 and the tank body 40 from above and from the outside in the vehicle width direction. The upper surface portion 51 of the cover 50 is fastened to the front plate 31 of the bracket 30 and the back plate 44 of the tank body 40 by bolts. As shown in Fig. 7, both the upper surface portion 51 and the side surface portion 52 of the cover 50 extend rearward in the vehicle front-rear direction beyond the back plate 44 of the tank body 40. More specifically, the upper surface portion 51 and the side surface portion 52 extend rearward in the vehicle front-rear direction beyond a liquid level indicator portion 65 described later, i.e., toward the driver's seat 9.

[0022] In the liquid agent tank 60 configured as above, the back plate 44 of the tank body 40, i.e., the back surface 60a of the liquid agent tank 60, is provided so as to be exposed toward the driver's seat 9. A liquid level indicator 65 is provided on the back surface 60a. In the first embodiment, the liquid level indicator 65 is a level gauge 70 as a liquid level gauge. The level gauge 70 has a colorless and transparent cylinder 71 extending in the vertical direction, and the upper end and the lower end of the cylinder 71 are fastened to the back surface plate 44 by bolts. The level gauge 70 communicates with the inside of the liquid agent tank 60 through passages formed at the upper end and the lower end, and displays the liquid level (level) of the liquid agent stored in the liquid agent tank 60 by the liquid agent flowing in from inside the liquid agent tank 60. The level gauge 70 is disposed on the outer side in the vehicle width direction than the outer end 3fa of the front rolling wheel 3f in the vehicle width direction, as shown by the dashed line and the solid line arrow in FIG. 8.

[0023] As described above, the tire roller 1 (rolling machine) of the first embodiment includes the driver's seat 9, the front rolling wheel 3f provided in front of the driver's seat 9, a liquid agent spraying nozzle 18 that sprays a liquid agent onto the front rolling wheel 3f, and a liquid agent tank 60 that stores the liquid agent. The liquid agent tank 60 is provided above the front rolling wheel 3f and is provided so that at least a portion of it is exposed toward the driver's seat 9, and the portion of the liquid agent tank 60 exposed toward the driver's seat 9 (back surface 60a) includes a liquid level indicator 65 that indicates the liquid level of the liquid agent stored in the liquid agent tank 60.

[0024] With this configuration, the driver seated in the driver's seat 9 can visually check the liquid level display unit 65 on the back surface 60a of the liquid tank 60, so that the driver can easily check the amount of liquid stored in the liquid tank 60 even while the tire roller 1 is in operation. In addition, for example, even when the driver or other workers are on the ground, the liquid level display unit 65 can be easily visually checked. This makes it possible to suppress forgetting to perform pre-work inspection, and to avoid insufficient maintenance of the liquid. In addition, even if the driver forgets to check the amount of stored liquid before getting on the floor 4 where the driver's seat is located, the liquid level display unit 65 can be checked even after sitting on the driver's seat as described above. Furthermore, since the inspector does not need to get on and off the floor 4 where the driver's seat is located to check the amount of stored liquid, the burden on the inspector can be reduced and the work efficiency of the inspection work can be improved. Therefore, according to the tire roller 1 of the embodiment, it is possible to easily check the amount of stored liquid in the liquid tank 60.

[0025] The liquid level display unit 65 is a level gauge 70 (liquid level gauge) attached to the back surface 60a. With this configuration, even if the liquid agent tank 60 is made of a metal material, the liquid level display unit 65 can be provided using the level gauge 70.

[0026] The tire roller 1 also includes a fender shield 25 that covers the front rolling wheel 3f from above, the liquid agent spraying nozzle 18 is disposed above the front rolling wheel 3f, and a gap S is formed between the fender shield 25 and the front rolling wheel 3f so that the liquid agent spraying nozzle 18 is exposed toward the driver's seat 9. With this configuration, the driver seated in the driver's seat 9 can visually check the state of spraying of the liquid agent from the liquid agent spraying nozzle 18 through the gap S.

[0027] In addition, the level gauge 70 (liquid level display unit 65) is provided on the outer side in the vehicle width direction than the front rolling wheels 3f. This configuration makes it possible to prevent mud splashes caused by the front rolling wheels 3f and water or liquid agent sprayed from each nozzle 17, 18 from adhering to the level gauge 70.

[0028] The fender shield 25 also includes a liquid agent tank 60 and a cover 50 that covers the liquid agent tank 60 from above, and an upper surface portion 51 of the cover 50 extends toward the driver's seat 9 side beyond the liquid level display portion 65. With this configuration, the upper surface portion 51 of the cover 50 can be used as a rain or sunshade for the level gauge 70 attached to the back panel 44, and the upper surface portion 51 can also prevent dust and other dirt from adhering to the level gauge 70 from above.

[0029] Moreover, the cover 50 covers the side panel 33 of the liquid agent tank 60 and includes a side portion 52 that extends toward the driver's seat 9 side beyond the liquid level display unit 65. With this configuration, the side portion 52 of the cover 50 can prevent dust and other dirt from adhering to the level gauge 70 attached to the back panel 44 from the outside in the vehicle width direction.

[0030] [Second embodiment] Next, a liquid tank according to a second embodiment will be described with reference to Figs. 9 to 11. Fig. 9 is a perspective view showing the liquid tank according to the second embodiment. Fig. 10 is a perspective view showing the attached state of the liquid tank according to the second embodiment. Fig. 11 is a perspective view showing the back side of the liquid tank according to the second embodiment. In the second embodiment, the tire roller 1 has the same configuration as the first embodiment except for the liquid tank 80 shown in Figs. 9 to 11, so the same configuration will not be described and the same reference numerals will be used.

[0031] The liquid agent tank 80 is formed in a housing shape using a colorless, transparent or translucent resin material. As in the first embodiment, the liquid agent spraying pump 62 is attached to the front surface 81 of the liquid agent tank 80 by bolting via a flat mounting member 46. In addition, a liquid agent supply port 85 for supplying the liquid agent into the liquid agent tank 80 is provided on the upper surface 82 of the liquid agent tank 80, and a removable cap 87 is attached to the liquid agent supply port 85. In addition, rectangular recesses 88 are formed over the front surface 81, the upper surface 82, and the lower surface 83 near both ends in the vehicle width direction of the liquid agent tank 80 in the attached state. As shown in FIG. 10, a band-shaped fixing device 89 is wound around each recess 88. Both ends of each fixing device 89 are attached to a rear panel 90 described later.

[0032] A back plate 90 that forms the back surface of the fender shield 25 is provided on the back surface 80a of the liquid agent tank 80. The back plate 90 is formed of a metal material and covers the back surface 80a of the liquid agent tank 80 from the rear side in the vehicle front-rear direction. The back plate 90 is disposed between the side plates 32 and 33 of the bracket 30, and is joined to the side plates 32 and 33 at both ends in the vehicle width direction. In addition, as shown in FIG. 11, the back plate 90 has an opening 92 that exposes a part of the back surface 80a of the liquid agent tank 80 to the driver's seat 9 side. Therefore, the driver seated in the driver's seat 9 can visually check the back surface 80a of the liquid agent tank 80 through the opening 92, and can check the position of the liquid surface in the liquid agent tank 80 formed of a colorless, transparent or translucent resin material. In other words, the back surface 80a of the liquid agent tank 80 and the opening 92 form a liquid surface display unit 95 in the second embodiment.

[0033] As described above, the liquid agent tank 80 of the second embodiment is formed of a transparent or semi-transparent resin material, and the fender shield 25 includes a back plate 90 that covers the back surface 80a of the liquid agent tank 80, and the back plate 90 has an opening 92 that exposes a part of the back surface 80a of the liquid agent tank 80 to the driver's seat 9 side. With this configuration, as in the first embodiment, the driver can easily check the amount of liquid agent stored in the liquid agent tank 80 even while the tire roller 1 is in operation. In addition, even when the driver or other workers are on the ground, the liquid level display unit 95 can be easily viewed. Therefore, it is possible to easily check the amount of liquid agent stored in the liquid agent tank 80, perform maintenance of the liquid agent more appropriately, and more appropriately spray the liquid agent to the front rolling wheels 3f. In addition, the liquid agent tank 80 can be formed of a resin material, which can reduce weight and suppress the occurrence of corrosion such as rust.

[0034] Although the description of the embodiment is finished above, the aspect of the present invention is not limited to this embodiment. For example, the rolling machine is not limited to the tire roller 1, but may be a vibrating roller, a macadam roller, a tamping roller, or the like. In addition, the liquid agent tanks 60, 80 may be arranged above the front rolling wheel 3f so that at least a part of them is exposed toward the driver's seat 9, not limited to the back surface 60a, 80a, and the liquid level display units 65, 95 may be provided on the part of the liquid agent tanks 60, 80 exposed toward the driver's seat 9.

[0035] In the first embodiment, the level gauge 70 may be capable of at least checking the amount of hydraulic oil in the liquid tank 60, and the cylindrical body 71 may not be colorless. The level gauge 70 may be attached on the inner side in the vehicle width direction than the outer end 3fa of the front rolling wheel 3f in the vehicle width direction, as long as it is visible to the driver seated in the driver's seat 9.

[0036] In the second embodiment, the liquid agent tank 60 may be made of a resin material that is not necessarily colorless, as long as it allows at least the amount of hydraulic oil in the liquid agent tank 60 to be confirmed. The opening 92 forming the liquid level indicator 95 may be formed only outside the vehicle width direction outer end 3fa of the front rolling wheel 3f. This can prevent mud splashing by the front rolling wheel 3f and water and liquid agent sprayed from each nozzle 17, 18 from adhering to the back surface 80a of the liquid agent tank 80 through the opening 92.

[0037] Furthermore, the top surface portion 51 and the side surface portion 52 of the cover 50 do not have to extend beyond the liquid level indicating portions 65, 95 to the driver's seat 9 side. [Explanation of symbols]
