Description

Technical Field

[0001] This invention relates to the technical field of asphalt concrete, specifically to asphalt concrete processing methods. Background Technology

[0002] Asphalt concrete is a mixture of asphalt and aggregates in a certain proportion. It is now widely used for road paving and has the advantages of smooth surface, seamlessness, comfortable driving, low vibration, low noise, wear resistance, dust-free and easy cleaning, short construction period, simple maintenance and repair, recyclability, and suitability for phased construction. However, when processing asphalt concrete, it is necessary to add sand and gravel for mixing. Directly crushed sand and gravel will contain some impurities, which will affect the quality of asphalt concrete processing.

[0003] While existing equipment can screen gravel of different sizes and mix it with heated asphalt, and can process asphalt concrete by controlling the ratio between the two, existing equipment does not have the function of cleaning the gravel before mixing it with asphalt. Directly adding crushed and screened gravel to asphalt will affect the adhesion between the gravel and asphalt, thus affecting the quality of the asphalt concrete and failing to meet the requirements. Therefore, an asphalt concrete processing method is proposed. Summary of the Invention

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. This invention utilizes a motor in the mixing mechanism to drive a cam to rotate. The cam's rotation intermittently pushes a slider on the side of the rotating wheel to slide inside the storage bin, intermittently conveying heated asphalt from the storage bin to the mixing chamber. Simultaneously, the movement of the moving block drives the upper screen plate and the outlet to move, intermittently adding cleaned gravel into the mixing chamber. The rotation of the first gear drives the first rotating shaft to rotate, which in turn drives a fixed column to rotate inside the rotating shell. The fixed column, through a groove on its surface, causes the mixing blade at one end of the sliding rod to flip, thoroughly mixing the gravel with the heated asphalt. This improves the efficiency of asphalt concrete processing and reduces the labor intensity of workers.

[0022] 2. In this invention, the rotation of the first rotating shaft drives the connecting block to rotate, which in turn drives the moving rod to move. The moving rod, through the first universal joint, drives the first sliding sleeve to move. The movement of the first sliding sleeve drives the moving block at one end of the folding rod to move. The moving block drives the limiting post to move. The movement of the limiting post drives the second gear to mesh and rotate with the rack inside the V-groove. The rotation of the second gear drives the second rotating shaft to rotate. The rotation of the second rotating shaft drives the water nozzle below the second sliding sleeve to extend and retract while spraying water to clean the sand and gravel. This improves the efficiency of the water nozzle in cleaning the sand and gravel. At the same time, the wastewater after cleaning can flow into the water tank through the outlet, allowing the wastewater to be recycled and saving water resources.

[0023] 3. In this invention, the upper screen plate and the outlet rotate in opposite directions. The rotation of the upper screen plate can transfer the surface gravel to the inside of the mixing tank, while the rotation of the outlet can discharge wastewater. At the same time, the rotation of the upper screen plate drives the lower corrugated plate to move, which comes into contact with the upper corrugated plate driven by the rotation of the outlet. This causes the upper screen plate and the outlet to vibrate, preventing impurities left after cleaning from clogging the device. Meanwhile, the contact between the support rod and the convex plate can drive the hopper to vibrate, which can prevent gravel from clogging the discharge port below the hopper, thus avoiding affecting the processing efficiency of subsequent asphalt concrete and improving the service life of the device.

[0051] like Figure 5 As shown, the feeding assembly 300 includes an upper screen plate 301, which is located above the moving block 209. A feeding plate 305 is rotatably connected to the rear of the upper screen plate 301 via a pin. A feeding hopper 10 is provided above the feeding plate 305.

A lower wedge block 309 is provided behind the upper wedge block 308. An outlet 304 is fixedly connected above the lower wedge block 309.

[0052] like Figure 5As shown, the side of the upper screen plate 301 is fixedly connected to the lower wave plate 302 by a pin, the side of the outlet 304 is fixedly connected to the upper wave plate 303 by a pin, a water tank 7 is provided below the outlet 304, and support frames 8 are arranged at four corners below the water tank 7. The lower end of the support frame 8 is fixedly connected to the working box 1. Two sets of rotating gears 310 and racks 311 are symmetrically arranged along the upper screen plate 301.

[0053] Furthermore, the piston cylinder 12 is connected to the interior of the mixing tank 6, and the interior of the water outlet pipe 13 and the water inlet pipe 16 are both equipped with one-way valves. The surface of the fixed column 107 is provided with an arc-shaped groove. The discharge pipe 3 is connected to the interior of the mixing tank 6. The shape of the hopper 10 is trapezoidal. The water storage plate 211 is fixedly connected to the hopper 10. The rack 311 slides on the support plate on the side of the water tank 7. The second rotating shaft 214 is connected to the interior of the V-groove 212.

[0054] Working principle: After installation, the heated, viscous asphalt is first added to the storage tank 5, and then crushed and screened gravel is added to the hopper 10. The discharge pipe 3 is blocked by a baffle 4. Then, the motor 101 is started, driving the incomplete gear 104 to rotate. The incomplete gear 104 meshes and drives the first gear 105 to rotate, which in turn drives the turntable 103 to rotate. The rotation of the turntable 103 drives the fixed frame 102 to rotate, while the motor 101 rotates simultaneously. The cam 111 rotates intermittently, which drives the rotating wheel 112 to move. The rotating wheel 112 drives the slider 113 to slide inside the storage box 5. While the slider 113 is sliding, it drives the spring column 114 to move. The spring column 114 drives the scraper 115 to slide inside the storage box 5. The scraper 115 is limited by the limiting rod 116, which can transport the heated asphalt to the top of the feed pipe 9. The heated asphalt can be intermittently added into the mixing tank 6 through the feed pipe 9.

[0055] When the first gear 105 rotates, it drives the connecting block 201 to rotate. The connecting block 201 drives the moving rod 202 to move through the hinge ball. The moving rod 202 drives the first universal joint 203 to move. The first universal joint 203 drives the rectangular column 204 to move left and right through the hinge ball. The left and right movement of the rectangular column 204 drives the first sliding sleeve 205 to move. The movement of the first sliding sleeve 205 drives the folded rod 208 to move. The movement of the folded rod 208 drives the moving block 209 to move. The movement of the moving block 209 drives the upper screen plate 301 to rotate around the rotating gear 305. The shaft of 10 rotates, and the upper screen plate 301 drives the feed plate 305 to move below the feed hopper 10 via the pin. This blocks the feed inlet below the feed hopper 10, preventing sand and gravel from continuing to fall from the feed hopper 10 through the feed plate 305 onto the surface of the upper screen plate 301. At the same time, the first sliding sleeve 205 drives the piston rod 14 to slide inside the piston cylinder 12 via the second universal joint 206, which can draw water from the water tank 7 into the water storage plate 211. The movement of the moving block 209 drives the limit post 210 to move, and the movement of the limit post 210 drives the limit post 210 to move. The second gear 213 meshes and rotates inside the V-groove 212. When water inside the water storage plate 211 is transferred to the spray nozzle 216 via the second rotating shaft 214, the rotation of the second gear 213 drives the second rotating shaft 214 to rotate as well. The rotation of the second rotating shaft 214 drives the spray nozzle 216 to rotate. Because the spray nozzle 216 slides inside the second sliding sleeve 215, it can reciprocate and extend during rotation. The sprayed water can thoroughly clean the sand and gravel on the surface of the upper screen plate 301. When the cleaned impurities pass through... After the mesh filters the water, the upper screen plate 301 rotates, which drives the rotating gear 310 to rotate. The rotating gear 310 rotates, which drives the rack 311 to move. The rack 311 moves, which drives the upper wedge block 308 to push the lower wedge block 309 to move. The lower wedge block 309 moves, which drives the outlet 304 to rotate, so that the wastewater after cleaning can be discharged into the water tank 7. Then, the water inside the water tank 7 is filtered by the filter plate 15 on the side of the water tank 7. The filtered water is then transported to the piston cylinder 12 through the water inlet pipe 16 and reused repeatedly.

[0056] After the gravel is cleaned, the upper screen plate 301 rotates to a certain angle to add the gravel into the mixing tank 6. At the same time, the first gear 105 rotates, driving the first rotating shaft 106 to rotate. The first rotating shaft 106 rotates, driving the fixed column 107 to rotate. The fixed column 107 drives the slide rod 108 to flip on the surface of the rotating shell 109 through the sliding groove on its surface. The slide rod 108 rotates, driving the mixing blade 110 to rotate. The rotation of the mixing blade 110 can mix and stir the asphalt and gravel that have fallen into the mixing tank 6, which can fully bind the two together and improve the quality of asphalt concrete manufacturing.

[0057] As the washed gravel slides from the surface of the upper screen plate 301 into the mixing tank 6, the first sliding sleeve 205 intermittently pushes the feeding plate in front of the upper screen plate 301 through the ball above to make it vibrate, so that the gravel can be evenly sprinkled into the mixing tank 6 and fully mixed with the asphalt, thus avoiding accumulation and insufficient contact with the asphalt.

[0058] Furthermore, when the connecting block 201 drives the moving rod 202 to move, the other end of the moving rod 202 pushes the sliding plate 207 to slide inside the working box 1 through the hinge ball. The sliding of the sliding plate 207 drives the support rod 306 to move back and forth. The movement of the support rod 306 contacts the convex plate 307, which can drive the hopper 10 to vibrate. This can prevent a large amount of sand and gravel from blocking the discharge port below the hopper 10. Moreover, when the upper screen plate 301 and the outlet 304 rotate in opposite directions at the same time, the upper wave plate 303 on the side of the outlet 304 contacts the lower wave plate 302 on the side of the upper screen plate 301, causing them to vibrate. This can make the sand and gravel cleaner.

[0059] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the scope and spirit of the invention, the scope of which is defined by the claims and their equivalents.
