[0005] In view of these problems, an object of the present invention is to provide a system, an apparatus, and a method for quickly removing and collecting unwanted materials on road surfaces. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention has the following features: The present invention is a road surface waste material removal system for sucking and removing waste material present on a road surface, and includes a compressed air jetting unit for jetting compressed air toward the road surface, a suction duct for sucking in waste material that has been splashed off the road surface by the compressed air jetted from the compressed air jetting unit, a suction cart on which the compressed air jetting unit and suction duct are installed, a hose connected to the suction duct, a negative pressure generator connected to the hose for generating negative pressure in the suction duct, a tank for collecting the waste material sucked in by the negative pressure generator, and a compressor for sending compressed air to the compressed air jetting unit.

[0007] Preferably, the compressed air ejection section is capable of ejecting compressed air intermittently.

[0008] Preferably, the compressed air jet is attached to the inner wall of the suction duct.

[0009] Preferably, a plurality of compressed air jetting portions are attached to the inner wall of the suction duct.

[0015] Preferably, the tank has an angle-shaped plate member provided with a vibration device therein.

[0016] Preferably, the tank has an openable bottom.

[0017] The present invention also provides a method for removing unwanted road surface material by sucking it up and removing it, comprising a compressed air ejection step for ejecting compressed air toward the road surface, a suction step for sucking in unwanted material that has been splashed off the road surface by the compressed air ejected in the compressed air ejection step using negative pressure inside a suction duct, and a recovery step for recovering the unwanted material sucked in in the suction step into a tank via a hose.

[0018] The present invention also provides a suction trolley used in a road surface waste removal system for sucking up and removing waste material present on the road surface, comprising a compressed air ejection unit for ejecting compressed air toward the road surface, a suction duct for sucking up waste material that has been splashed off the road surface by the compressed air ejected from the compressed air ejection unit, and a trolley on which the compressed air ejection unit and suction duct are installed.

[0024] By arranging the compressed air jetting sections at intervals of approximately 90 degrees, approximately 90 degrees, and approximately 180 degrees, there will be no compressed air jetting section at approximately 180 degrees in the direction of travel, making it possible to smoothly collect unwanted materials.

[0025] If the compressed air ejection section is adjustable in height or angle, the compressed air can be directed at the unwanted materials from an appropriate height or angle depending on the condition of the collected materials, making it easier to collect the unwanted materials.

[0026] If the lower part of the suction duct is made flexible, it becomes easier to collect unwanted materials regardless of the road surface conditions.

[0027] By providing a suction direction compressed air jet, unwanted materials can be forcefully sent towards the hose.

[0028] Providing a hose carrier makes the work easier.

[0029] If a mountain-shaped plate member (with a vibrator) is installed inside the tank, bridge formation can be prevented and unwanted materials can be easily collected.

[0030] Making the bottom of the tank retractable makes it easier to collect unwanted materials.

[0031] These and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. [Brief explanation of the drawings]

[0033] As shown in FIGS. 1A and 2, the road surface waste removal system 1 includes a suction cart 2, a hose 3, a compressor 4, a negative pressure generating device (blower) 5, a recovery duct 6, and a tank . The compressor 4, negative pressure generator 5, recovery duct 6, and tank 7 are placed on the bed of a truck using a crane or the like, but this is not limited to this. A dedicated vehicle equipped with the compressor 4, negative pressure generator 5, recovery duct 6, and tank 7 may also be used. As shown in Fig. 1B, the suction cart 2 can be placed next to the negative pressure generator 5 of the vehicle (or next to the compressor 4 or tank 7, or any other available space). This allows the suction cart 2 to be loaded onto the vehicle, driven to the work site, and then unloaded from the vehicle as shown in Fig. 1A to begin work.

[0034] As shown in Figures 3 to 5, the suction cart 2 includes a base 20, three wheels 21, suction ducts 22 and 23, an under-mirror 24, a handrail 25, an air manifold block 26, three compressed air outlets 27a, 27b, and 27c, three inner wall surface plates 28a, 28b, and 28c, position adjustment L-shaped brackets 29a, 29b, and 29c, and a plurality of adjustment bolts 30. The wheels 21 are fitted with well-known stoppers 21a as needed.

[0035] As shown in FIG. 2, the negative pressure generator 5 generates negative pressure to suck up the unwanted material below the suction cart 2 via the hose 3 and collect it from the collection duct 6 into the tank 7 . 2, the compressed air generated by the compressor 4 is connected to cocks provided on the air manifold 26, and the compressed air can be ejected from the tips of the compressed air ejection portions 27a, 27b, and 27c. The amount of compressed air ejected from each of the compressed air ejection portions 27a, 27b, and 27c can be adjusted by adjusting the opening and closing amount of the corresponding cock.

[0036] The compressed air ejectors 27a, 27b, and 27c may be devices that simply eject compressed air, or devices that eject compressed air intermittently in pulses. An example of a device that ejects compressed air intermittently is the "Pulse Blow" by Koganei Corporation, but this is not limited thereto.

[0037] A suction duct 22 is attached to the underside of the base 20 via an upper flange. The suction duct 22 has a cylindrical duct body 22b with a flange at its top, and a bellows-like flexible duct 22a provided at the bottom of the duct body 22b.

[0038] Inner wall surface plates 28a, 28b, and 28c are attached to the inner wall of duct main body 22b at intervals of approximately 90 degrees, approximately 90 degrees, and approximately 180 degrees. Position adjustment L-shaped brackets 29a, 29b, and 29c are attached to inner wall surface plates 28a, 28b, and 28c, respectively. Position adjustment L-shaped brackets 29a, 29b, and 29c each have an elongated hole and are attached with a plurality of adjustment bolts 30 so that the compressed air ejection portions 27a, 27b, and 27c can be adjusted up and down in position.

[0039] As a result, the compressed air ejection parts 27a, 27b, 27c are attached so that their height positions can be adjusted inside the suction duct 22. However, the means for adjusting the positions is not limited to the structure shown in the drawing. Furthermore, horizontal elongated holes may be provided in addition to the vertical elongated holes, so that the angles of the compressed air ejection parts 27a, 27b, and 27c can be adjusted.

[0040] In FIG. 3, the piping for supplying air from the air manifold 26 is simply shown, but it may be arranged in an appropriate position.

[0041] A suction duct 23 is provided on the upper surface of the base 20. The suction duct 23 is connected to the base 20 and the suction duct 22 via a flange, as shown in Fig. 4. In Fig. 4, the suction duct 23 is shown as being fixed laterally offset to connect to the hose 3, but this is not intended to be limiting.

[0042] Three wheels 21 are attached to the platform 20. Stoppers 21 may be attached to the wheels 21 as needed, but as stoppers are well known means, they will not be described in detail. The work vehicle can move the suction cart 2 while holding onto the handrail 25.

[0043] If oil, gasoline, diesel, or other substances leak onto the road surface, a work vehicle sprinkles a general-purpose liquid road surface absorbent onto the oil, etc., and mixes it with a shovel or other tool, allowing the components to be absorbed by the absorbent. Next, while operating the negative pressure generator 5 and the compressor 4 (or operating them at an appropriate timing), the worker moves the suction duct 22 of the suction cart 2 to above the adsorbent. Then, while compressed air is sprayed from the compressed air jetting portions 27a, 27b, and 27c (or, depending on the device, compressed air is sprayed intermittently), the suction force of the negative pressure generating device 5 is used to recover the adsorbent material that has adsorbed oil, etc., into the tank 7 through the suction ducts 22, 23 and the hose 3.

[0044] A plate member 71 with a mountain-shaped cross section is attached inside the tank 7, and a mechanism has been introduced to prevent the collected waste material from solidifying into an arch shape, a phenomenon known as bridging. Furthermore, to further ensure that bridging is prevented, a vibration device 72 such as an electric or hydraulic motor is attached to the bottom of the plate member 71, and the plate member 71 is vibrated at appropriate times to reliably prevent bridging.

[0045] 2, the lower part of the tank 7 is formed by a bottom member 73 that opens and closes by lowering an opening / closing lever 70. Any known technology can be used for opening and closing the lower part of the tank, so a detailed description will be omitted. The unwanted materials collected in the tank 7 are disposed of by opening and closing the bottom member 73 and then being placed in a bag or the like.

[0046] In this embodiment, compressed air is sprayed onto the road surface, so that any adsorbent that has gotten into gaps in the road surface, such as asphalt or concrete, is bounced off by the force of the compressed air being sprayed, and the adsorbent in the gaps and any oil that has not been completely adsorbed are also sucked up.

[0047] If the adsorbent material is sucked in using only the negative pressure from the negative pressure generator 5 without injecting compressed air, only the material present on the surface of the road surface will be sucked in, and it will be difficult to suck in material that has gotten into gaps. However, with this embodiment, it is possible to suck in material even deep inside gaps. If unwanted materials deep in the gaps are not sucked up, for example, if it rains afterwards, oil or the like after a traffic accident may float up to the road surface, which is extremely dangerous. Therefore, the suction deep into the gaps achieved by this embodiment can be said to be extremely effective.

[0048] Next, optional configurations will be described. As shown in Figure 4, the suction duct 23 is connected to the compressor 4 and is provided with a suction direction compressed air ejection section 31 for ejecting compressed air in the suction direction (the direction of the arrow in Figure 4) inside the suction duct 23. The suction direction compressed air jetting portion 31 sends the floating adsorbent, etc., towards the hose 3 more quickly, thereby enabling the adsorbent, etc., to be sucked in reliably.

[0049] Furthermore, if the hose 3 is long, it may be difficult to handle. Therefore, a hose carrier 8 for carrying the hose 3 may be used. As shown in FIG. 6, the hose carrier has a structure in which three wheels 80 each having a stopper 81 are attached to the underside of a base 84. Two inverted U-shaped frames 83 are provided on the top surface of the platform 84, through which the hose 3 is passed. Also, handrails 82, 82 are provided on the left and right sides to facilitate movement as needed.

[0050] The structure shown in Figure 4 is merely one example, but in this way, the waste removal system 1 may be provided with a movable hose carrier 8 for carrying the hose 3, which makes it easier to handle the hose 3 and improves work efficiency.

[0051] Furthermore, in the above embodiment, the adsorbent is used to adsorb oil and the like, but it is also effective for absorbing broken glass, metal fragments, and the like that are scattered on the road surface.

[0052] In this embodiment, the compressed air jet unit is provided on the inner wall of the suction duct, but it can also be provided on the outer wall to eject unwanted material that has fallen into gaps in the road surface. Therefore, the compressed air jet unit is preferably attached to the inner wall of the suction duct, but may also be attached to the outer wall.

[0053] Although the present invention has been described in detail above, the above description is merely illustrative of the present invention in all respects and is not intended to limit its scope. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention. Each of the constituent elements of the invention disclosed in this specification is considered to be an independent, stand-alone invention. Inventions that combine the constituent elements in any manner are also included in the present invention. The specific expressions in this specification are merely examples, and the present invention also includes those that conceptualize these exemplary expressions. [Industrial Applicability]
