Title of Invention | A CHIP SEALER VEHICLE WITH A COMBINED AGGREGATE BIN |
---|---|
Abstract | Synchronized chip sealer vehicle includes a truck chassis, an asphalt tank, a chip hopper, an asphalt spraying system, and a chip spreading system. The combined aggregate bin includes two parts: a stationary hopper and a moveable bin, which are connected by using a rotating shaft. The lift mechanism is connected to the bottom of the moveable bin. The chip sealer vehicle does not utilize the traditional dumping method used by conventional chip sealer vehicles by raising the entire hopper body for dumping. Therefore, the chip sealer vehicle can properly work under height- restricted conditions, such as when under an overpass, cable lines, or inside tunnels. In addition, its center of gravity also is moved forward to ensure a more safer and stable drive condition. Moreover, the hopper can also be designed to be bigger for meeting specific requirements. |
Full Text | BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a road maintenance equipment, and in particularly, to a hopper system for a chip sealer vehicle. The Prior Arts For the sake of progress and economic development of society, transportation now plays a very important role in every part of our lives. A good road pavement structure usually consists of subgrade, prime coat, seal coat, hot mix asphalt (HMA), and surface course. The seal coat and the surface course application procedures are vital to the pavement quality. Synchronized surface dressing technology is the latest technology. The asphalt and the chips are sprayed and spreaded at the same time to achieve a maximum surface wrappage to the chips for improving wearability, skid resistance, water-proofing, and consequently prolonging the road's service life, and achieving cost reductions. The chip sealer vehicle utilizing synchronized surface dressing technology is currently the more advanced system used today. In Europe, above 95% road pavements have adopted this synchronized technology and machinery; the chip sealer vehicle includes a truck chassis, an asphalt tank, a hopper, an asphalt spraying system, and a chip spreading system. During use, the asphalt system sprays the asphalt simultaneously as the hopper raises one end to dump the chips under the control of the chip spreading system. When the hopper is raised to a 45°angle in order to completely dump the chips, the center of gravity is shifted to the back, and is normally led to weight imbalance and thus creating trouble during driving. On the other hand, the raised hopper during operation has a relatively substantial height; therefore, it is also not suitable for used under overpass, cable lines, or inside tunnels. 2 SUMMARY OF THE INVENTION The chip sealer vehicle according to the present invention overcomes the shortcomings of the existing synchronized surface dressing equipments to provide a safer drive, and a broader application range to more construction sites. The present invention improves upon the hopper system of the traditional chip sealer vehicle. The hopper, according to the present invention, comprises a two-part hopper system, which includes a stationary hopper and a moveable bin. The moveable bin is placed inside the stationary hopper; and they are movably connected by a rotating shaft. At the bottom of the movable bin, the moveable bin is connected to the lift mechanism. Usually, the moveable bin is placed at the bottom of the stationary hopper. During use, chips are loaded to the hopper; and the truck is driven to the construction site. Later, the chip spreading system is then started. The chips inside the stationary hopper ar3e dumped to the chip spreader. As the stationary hopper is approaching empty, the lift mechanism is actuated, and the moveable bin is raised to dump the chips into the stationary hopper slowly until the moveable bin is empty. At the same time, the asphalt is sprayed to the road. The advantage of the present invention is that it changes the dumping method for the aggregate hopper of raising the entire hopper body. The chip sealer vehicle according to the present invention can work in reduced headroom. In addition, its center of gravity is also moved forward to ensure a safer and more stable drive. Moreover, the hopper can be designed to be bigger for meeting specific requirments of the user. The chip sealer vehicle according to the present invention can be used for the seal coat, surface course, anti-wear material paving, layer paving, and the spraying or 3 spreading of asphalt and chips under certain specialized circumstances, respectively. It is suitable for use for various grades of road construction, with good quality and high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS The present invention will be apparent to those skilled in the art by reading the following detailed description of an embodiment thereof, with reference to the attached drawings, in which: Fig.i Structural layout of a chip sealer vehicle according to an embodiment of the present invention;. Fig.2 Side view of a combined aggregate bin according to the embodiment; and Fig.3 A perspective view of a moveable bin according to the embodiment. truck chassis, ٱ 2 ٱ asphalt tank, (3) combined aggregate bin, (4) asphalt spraying system, (5) chip spreading system, (31) hydraulic ram seat, (32) lift mechanism, (33) moveable bin, (34) stationary hopper, (35) rotating shaft DETAILED DESCRIPTION OF THE EMBODIMENT The illustration of the present invention are provided in conjunction with schematic diagrams hereafter: A chip sealer vehicle according to an embodiment of the present invention comprises of a truck chassis 1, an asphalt tank 2, a stationary hopper 34, a moveable bin 33, a lift mechanism 32, an asphalt spraying system 4, and a chip spreading system 5. The "dustpan" shaped moveable bin 33 is disposed inside the stationary hopper 34, in which the front and top portions are open (as shown in 4 Fig.3). The moveable bin 33 is movably connected to the stationary hopper 34 by using the rotating shaft 35. And one end of the lift mechanism 32 (the main part of the lift mechanism 32 is a hydraulic ram seat 31) is connected to the bottom of the moveable bin 33. The other end of the hydraulic ram is movably connected to the hydraulic ram seat 31 disposed at the side beam fixed on the chassis 1. The asphalt spraying system 4 and the chip spreading system 5 are located at the lower back portion of the stationary hopper 3. 5 WE CLAIM: 1. A chip sealer vehicle, comprising: a truck chassis (l); an asphalt tank (2); a combined aggregate bin (3); an asphalt spraying system (4); and a chip spreading system (5), wherein the combined aggregate bin (3) is comprised of a stationary hopper (34) and a moveable bin (33); the moveable bin (33) is disposed inside the stationary hopper (34). the moveable bin (33) is connected to the stationary hopper (34) by using the rotating shaft (35), and one end of the lift mechanism (32) is connected to the bottom of the moveable bin. 6 2. The chip sealer vehicle as claimed in claim 1, wherein the lift mechanism (32) is a hydraulic ram, and one end of the hydraulic ram is connected to the bottom of the moveable bin (33), and the other end of the hydraulic ram is connected to the hydraulic ram seat (31) disposed at a side beam which is fixed on the chassis (1). Synchronized chip sealer vehicle includes a truck chassis, an asphalt tank, a chip hopper, an asphalt spraying system, and a chip spreading system. The combined aggregate bin includes two parts: a stationary hopper and a moveable bin, which are connected by using a rotating shaft. The lift mechanism is connected to the bottom of the moveable bin. The chip sealer vehicle does not utilize the traditional dumping method used by conventional chip sealer vehicles by raising the entire hopper body for dumping. Therefore, the chip sealer vehicle can properly work under height- restricted conditions, such as when under an overpass, cable lines, or inside tunnels. In addition, its center of gravity also is moved forward to ensure a more safer and stable drive condition. Moreover, the hopper can also be designed to be bigger for meeting specific requirements. |
