Definitions

  • the present invention relates to asphalt compactors, and more particularly, to a device for recirculating water for cleaning the drum surface of asphalt compactors.
  • Asphalt compactors are mobile vehicles used to compact asphalt in the construction of roads and foundations. Such compactors are generally equipped with two steel drums, one at each end of the machine. It is required that the exterior surface of drums used on such asphalt compactors should be properly watered and cleaned to prevent adherence of particles or other material during their use.
  • Water sprays and wipers are typically used for this purpose. Water sprays are to wet the drum surface, providing a coolant and lubricant to give protection, while wipers are to apply cleaning of the drum surface and to evenly distribute water across the drum surface. A partial coverage of water across the drum surface, occurring from a plugged or damaged water spray nozzle or through evaporation, causes a section of the drum surface to become dried. In that case, it is more likely that particles could adhere to the surface. This would jeopardize the finish requirements for the job and require rework of that section of the jobsite.
  • FIG. 1 shows a typical drum surface lubricating and cleaning device used on asphalt compactors having a water spray 101 and a spring-loaded wiper 102 which is in contact with the surface of drum 103.
  • a water tank 104 mounted on the frame is a water tank 104 joined to a pump (not shown) such that the pump is adapted to cause the water in the tank 104 to move into the spray 101 through a tube 105.
  • the present invention has been developed with attention paid to these problems encountered in the above-described related techniques. Therefore, the objects of the present invention include providing a device for cleaning the drum surface of asphalt compactors wherein the water wastage can be reduced, refilling period is longer, and eventually the machine can run continuously for longer hours.
  • the present invention employs the following arrangement.
  • a device for cleaning a drum surface of an asphalt compactor which has a water tank fixed to a body of the compactor, and a partition member installed in the tank and dividing the tank into an upper main tank section and a lower secondary tank section.
  • the lower secondary tank section has an opening formed at the front face facing to the drum, while all other sides are closed and air-tight.
  • the opening of the secondary tank section is tightly plugged by a scraper which is made of water absorbing, resilient and breathable material, including some water absorbing polymers or organic sponge like material such as Cocomat made from coir of coconut husks. The scraper is in contact with the drum surface.
  • the tube enables the upper main tank section to communicate with the lower secondary tank section.
  • the tube extends from the bottom of the lower secondary tank section to the top of the upper main tank section.
  • the floor of the secondary tank section is tapered toward the opened front face.
  • the water spreads on the drum and flows over the drum to come in contact with the scraper which will then absorb the water. Because of the tapered shape of the bottom of the secondary tank section, excess water in the scraper slowly leaks and it will be collected in the secondary tank section. Since this collected water can be reused, refilling period is longer, and eventually the machine can run continuously for longer hours.
  • FIG. 1 is a perspective view of a typical drum surface lubricating and cleaning device used on asphalt compactors
  • FIG. 2 is a schematic side view of the entire configuration of an asphalt compactor
  • FIG. 3a is a perspective view of a drum surface cleaning device according to an embodiment of the invention.
  • FIG. 3b is a section view of a drum surface cleaning device according to an embodiment of the invention
  • FIG. 2 illustrates the schematic configuration of an entire asphalt compactor.
  • a compactor 201 is composed of a front drum 202, a rear drum 203, a front body 204 and a rear body 205.
  • a driver’s seat 206 is mounted either on front body 204 or on rear body 205.
  • Two bodies 204, 205 are connected with each other by means of a pivot joint 207 so the vehicle can be steered.
  • Water sprays 208a, 208b and wipers 209a, 209b are provided for front drum 202 and rear drum 203, respectively.
  • FIG. 3a and 3b illustrate a drum surface cleaning device of asphalt compactors according to one embodiment of the present invention.
  • a water tank 301 is fixed to a body of the compactor adjacent to a drum 302.
  • the width of the water tank 301 is similar to that of the drum 302.
  • a partition member 303 is installed in the water tank 301.
  • the partition member 303 divides the tank 301 into an upper main tank section 301a and a lower secondary tank section 301b. It is preferable that the secondary tank section 301b is constructed as an integral part of the tank 301.
  • the tank 301 is generally air tight except for the front face of the secondary tank section 301b facing to the drum 302.
  • the front face of the secondary tank section 301b has an opening. The opening is tightly plugged by a scraper 304.
  • the scraper 304 is made of water absorbing, resilient and breathable material, including some water absorbing polymers or organic sponge like material such as Cocomat made from coir of coconut husks.
  • the outer end of the scraper 304 is exposed and resiliently contacts the surface of the drum 302.
  • the scraper 304 is made to cover the entire width of the drum 302 as well.
  • Protrusions 308a, 308b are formed on the floor and on the ceiling of the secondary tank section 301b, respectively, in order to securely put the inner end of the scraper 304 on a regular position.
  • the floor of the secondary tank section 301b is tapered toward the opened front face. That is, the floor of the secondary tank section 301b has an uphill slope toward the opened front face.
  • a tube 305 is installed between the upper main tank section 301a and the lower secondary tank section 301b.
  • the tube 305 enables the upper main tank section 301a to communicate with the lower secondary tank section 301b.
  • the tube 305 extends from the bottom of the lower secondary tank section 301b to the top of the upper main tank section 301a. Due to such design of the tube 305, the flow of water from the upper main tank section 301a to the lower secondary tank section 301b is prevented. Namely, water can only flow from the lower secondary tank section 301b to the upper main tank section 301.
  • Reference numerals 306a, 306b are water spray nozzles installed on a water spray tube extending along the width of drum 302.
  • Reference numeral 307 is an eccentric weight installed in the drum 302 to give a vibratory impact when the drum 302 rotates.
  • Reference numeral 309 is a water filling cap.
  • the tank 301 In an initial state of use, the tank 301, particularly the upper main tank section 301a, is filled with water.
  • the drum 302 rotates and the water pump (not shown) is activated to cause the water in the tank 301 to move to the spray nozzles 306a, 306b.
  • the sprayed water flows over the surface of the drum 302, and comes in contact with the scraper 304.
  • the water collected in the secondary tank section 301b is recirculated to the main tank section 301a through the tube 305 when the pump is activated. Namely, the tank 301 is being kept airtight except for the opened front face of the secondary tank section 301b which is plugged by the scraper 304. Since the scraper 304 is breathable, the pump generates a suction force which forces the water collected in the secondary tank section 301b to flow into the main tank section 301a.
  • water can be recirculated and reused. Consequently, refilling period is longer, and the machine can run continuously for longer hours. Additionally, water collected in the secondary tank can be used for other external usages by using a water tape or so.
  • drum surface cleaning devices according to the present invention are not limited to asphalt compactors shown in the embodiments, but can be widely used for various road surface compacting machinery.
  • the device for cleaning a drum surface of an asphalt compactor according to the present invention is useful in a compaction machine wherein the water wastage can be reduced, refilling period is longer, and eventually the machine can run continuously for longer hours.
