Description

Technical Field

[0001] This invention relates to the field of municipal engineering, and in particular to an asphalt paving device for highway engineering. Background Technology

[0002] Asphalt is a dark brown, complex mixture composed of hydrocarbons of varying molecular weights and their non-metallic derivatives. It is a high-viscosity organic liquid, mostly existing in liquid or semi-solid petroleum form, with a black surface, and is soluble in carbon disulfide and carbon tetrachloride. Asphalt is a waterproof, moisture-proof, and corrosion-resistant organic cementing material. It can be mainly classified into three types: coal tar pitch, petroleum asphalt, and natural asphalt. Coal tar pitch is a byproduct of coking. Asphalt is primarily used in coatings, plastics, rubber industries, and road paving.

[0003] Some municipal roads need to be paved with asphalt to facilitate vehicle traffic. In the process of paving asphalt roads, asphalt paving equipment is required. However, the existing asphalt paving equipment uses separate drive equipment for the movement, asphalt leveling and asphalt mixing. This results in a large number of devices, a high damage rate and high cost. Furthermore, the asphalt in the existing asphalt paving equipment may cause blockages when the asphalt is poured, making it difficult to spread the asphalt evenly. Summary of the Invention

A first rotating shaft is vertically fixedly installed on the output shaft of the first rotary motor. The bottom end of the first rotating shaft extends into the storage bin and is fixedly installed with a first mixing blade. A paving roller is horizontally provided in the middle of the bottom of the base. Drive wheels are provided at both ends of the rear side of the bottom of the base. A linkage mechanism is provided between the first rotating shaft, the paving roller, and the two drive wheels. A discharge port is provided at the bottom of the storage bin and on the top of the base. A baffle is rotatably connected inside the discharge port.

A drive mechanism for driving the second rotating shaft to rotate is provided on the side of the base. A uniform feeding mechanism is provided at the bottom of the base.

[0007] By incorporating a first mixing blade, the first rotary motor is activated during asphalt paving to drive the first rotating shaft, which in turn drives multiple first mixing blades to rotate, thereby mixing the asphalt in the storage tank and ensuring that the asphalt remains uniform.

[0008] In a preferred embodiment, the storage tank is fixedly installed on one side of the top of the base, and a battery and a controller are fixedly installed side by side on the other side of the top of the base. A push rod is welded obliquely to one side of the storage tank. Support legs are vertically welded to both ends of the front side of the bottom of the base. Steering wheels are screwed to the bottom of the two support legs. An L-shaped mounting plate is welded to the top of the storage tank. The first rotary motor is vertically fixedly installed at the bottom of the horizontal part of the L-shaped mounting plate. The first rotating shaft is rotatably connected to the storage tank. Multiple first stirring blades are provided and are evenly distributed on the surface of the part of the first rotating shaft located inside the storage tank.

[0009] The battery powers the controller, the first rotary motor, the second rotary motor, and the electric slide. The controller controls the opening and closing of the first rotary motor, the second rotary motor, and the electric slide. Two steering wheels facilitate the change of direction of the entire device. The L-shaped mounting plate provides support for the first rotary motor.

[0010] In a preferred embodiment, the linkage mechanism includes a first belt and a second belt. A second support plate is horizontally welded to the middle of one side of the storage bin. A vertical driven shaft is vertically rotatably connected to the middle of the second support plate. The first belt connects between the first rotating shaft and the vertical driven shaft. A third support plate is vertically welded to both ends of the middle of the bottom of the base. A leveling roller is horizontally rotatably connected between the two third support plates. A first horizontal driven shaft is horizontally welded to one end of the leveling roller. The first horizontal driven shaft passes through one of the third support plates and is rotatably connected to the third support plate.

A horizontal shaft passes through and is rotatably connected to the first support plate. Two drive wheels are fixedly installed at both ends of the horizontal shaft. A second horizontal driven shaft is horizontally welded to the center of the side of one of the drive wheels. The second belt connects between the first horizontal driven shaft and the second horizontal driven shaft.

[0011] With a linkage mechanism, the first rotating shaft drives the vertical driven shaft to rotate via the first belt. The vertical driven shaft drives the first driving bevel gear to rotate. The first driving bevel gear drives the first horizontal driven shaft to rotate via the first driven bevel gear. The first horizontal driven shaft drives the paving roller to rotate, thereby paving the asphalt. The first horizontal driven shaft drives the second horizontal driven shaft to rotate via the second belt. The second horizontal driven shaft drives the two drive wheels to rotate via the horizontal shaft, thereby driving the entire device forward. Thus, with only one drive device, asphalt can be mixed, the entire device can be driven forward, and asphalt can be paved, reducing equipment wear rate and cost, and the device has stronger linkage.

[0012] In a preferred embodiment, the drive mechanism includes a second rotary motor, which is horizontally fixedly mounted on the middle of one side of the base. A drive shaft is horizontally fixedly mounted on the top end of the output shaft of the second rotary motor. The drive shaft extends into the base and the baffle.

A second driven bevel gear is welded to the middle of the second rotating shaft. The second driving bevel gear and the second driven bevel gear mesh. Multiple second stirring blades are provided, and the multiple second stirring blades are evenly distributed on the top and bottom surfaces of the second rotating shaft.

[0013] Equipped with a drive mechanism, when asphalt needs to be laid, the second rotary motor is started to drive the drive shaft to rotate. The drive shaft drives the baffle to rotate, thus exposing the discharge port. The asphalt in the storage tank is discharged from the discharge port. The drive shaft also drives the second active bevel gear to rotate. The second active bevel gear drives the second rotating shaft to rotate through the second driven bevel gear, which in turn drives the second mixing blade to rotate. Together with the continuous rotation of the baffle, the discharged asphalt is stirred and cleared, preventing asphalt from clogging the discharge port.

[0014] In a preferred embodiment, the uniform feeding mechanism includes an electric slide table and a feeding hose. The electric slide table is horizontally fixedly installed on the front side of the bottom of the base. The top end of the feeding hose is connected to the bottom of the feeding port. An L-shaped connecting rod is fixedly installed at the output end of the electric slide table. A fixing ring is adhered to the outside of the feeding hose. The bottom end of the L-shaped connecting rod is welded to one side of the fixing ring.

[0015] With a uniform feeding mechanism, during the asphalt feeding process, the electric slide table is activated to drive the bottom end of the feeding hose to move back and forth through the L-shaped connecting rod and the fixing ring, thereby spreading the asphalt evenly on the road. After being flattened by the paving roller, the asphalt is ensured to be evenly spread on the road.

[0016] As can be seen from the above, the asphalt paving device for highway engineering provided by the present invention can mix asphalt, drive the entire device forward, and pave asphalt with only one drive device, reducing equipment wear rate and cost, and the device has stronger linkage; the rotation of the second mixing blade, together with the continuous rotation of the baffle, mixes and clears the asphalt being fed, preventing asphalt from blocking the feeding port; the asphalt is evenly laid on the highway, and then leveled with the paving roller to ensure that the asphalt is evenly laid on the highway.
